Rajendra Pachauri: “A ciência foi deixada de lado na COP” (O Estado de São Paulo)

JC e-mail 4398, de 05 de Dezembro de 2011.

Se ela estivesse no centro do debate sobre mudanças climáticas, ações não poderiam ser adiadas, afirma o cientista indiano Rajendra Pachauri, presidente do Painel Intergovernamental sobre Mudanças Climáticas (IPCC).

O cientista indiano Rajendra Pachauri, de 71 anos, presidente do Painel Intergovernamental sobre Mudanças Climáticas (IPCC), acompanha com frustração a 17.ª Conferência do Clima da ONU, a COP-17. O pesquisador, que concedeu entrevista ao Estado em uma pequena sala VIP no centro de convenções de Durban, avalia que a ciência e os alertas dados pelos cientistas não estão no centro das negociações climáticas.

Para ele, não é necessariamente fundamental garantir a segunda fase do Protocolo de Kyoto nessa reunião, mas é preciso que haja avanços independentemente do acordo que seja escolhido. “Gostaria que houvesse uma forma de tornar a ciência sobre clima uma parte mais central nas discussões nas negociações. Porque pelo menos assim você poderia dizer que não se pode adiar as ações por muito tempo. E tomar medidas pode ser realmente atraente, e não caro”, afirma. A reunião segue até sexta-feira.

Apesar dos alertas do IPCC e do recente relatório especial sobre eventos extremos que mostram os impactos das mudanças climáticas, o avanço nas negociações é muito lento. Como o senhor avalia essa situação?
Nas negociações que estão acontecendo aqui, nós não podemos perder de vista a ciência das mudanças climáticas. Você mencionou corretamente que recentemente publicamos um relatório especial sobre eventos extremos e desastres e como podemos avançar na adaptação (preparação para esses eventos). Eu gostaria de ver uma discussão muito mais focada nessas questões, e o que a comunidade global pode fazer para lidar com esses impactos.

O senhor acha importante focar mais em adaptação?
Acho que precisamos lidar com os dois, adaptação e mitigação (cortes de emissões de gases-estufa). Porque nós não teremos capacidade de nos adaptar a todos os impactos. Podemos nos adaptar a algumas situações, mas, depois de um certo tempo, fica muito difícil e caro fazer isso. Então, precisamos olhar para a mitigação também. Neste ano apresentamos um relatório sobre energias renováveis que claramente mostra que é possível usar muito mais energias renováveis e, com mais pesquisas em seu desenvolvimento, os custos podem cair. O que estou dizendo é que eu gostaria que houvesse uma forma de tornar a ciência sobre clima uma parte mais central nas discussões nas negociações. Porque pelo menos assim você poderia dizer que não se pode adiar as ações por muito tempo. E que tomar medidas pode ser realmente atraente, e não caro.

A ciência então não está no centro da discussão hoje?
Não parece estar. Não estou envolvido diretamente na negociação, mas a acompanho e não vejo a ciência no centro do debate.

As pessoas costumam dizer que os cientistas do IPCC eram radicais e pessimistas. Mas em dois anos novos estudos podem mostrar que a situação é ainda mais perigosa do que o previsto?
Não sei, ainda estamos trabalhando nesse relatório. No relatório especial sobre eventos extremos e desastres, nós apontamos as áreas em que ainda não temos muitas evidências e também as em que as evidências claramente mostram que ondas de calor aumentarão, assim como os eventos de precipitações extremas e a elevação do nível do mar – e isso é uma ameaça a áreas costeiras. Trouxemos todas as informações com um grande cuidado, de forma robusta. Ninguém pode dizer que alguém dentro do IPCC é radical.

Ao contrário, eu ia perguntar se os cientistas não estavam sendo cautelosos demais no relatório de 2007.
Temos muito mais evidências hoje, muito mais pesquisas publicadas sobre mudanças climáticas. E o IPCC funciona com a avaliação de pesquisas publicadas (o IPCC não faz as próprias pesquisas). E, agora, temos muito mais estudos do que nos anos anteriores ao quarto relatório do IPCC, de 2007. Certamente, estamos num nível muito melhor agora. É claro que em algumas partes do mundo temos grandes lacunas, não temos estudos em todos os locais e isso ocorre principalmente nos países mais vulneráveis.

A discussão em Durban tem focado muito no Protocolo de Kyoto. Em sua opinião, é importante ter um segundo período de compromisso de Kyoto? Ou podemos fazer outro tipo de acordo?
É muito difícil dizer, há uma diversidade enorme de opções que podem ser aceitas. Mas eu gostaria de ver um avanço, qualquer que seja a direção tomada, com Kyoto ou outra coisa. E, de novo, se houvesse um foco na ciência, talvez as pessoas veriam que há urgência em agir e as decisões seriam tomadas mais rapidamente.

O senhor acredita que países emergentes como China, Índia e Brasil devem fazer mais, já que são grandes emissores?
Não poderia dizer isso, mas de vou lembrar que as responsabilidades de acordo com a convenção do clima são comuns, mas diferenciadas (os países industrializados, maiores emissores históricos, têm as maiores responsabilidades). E é por isso que essas negociações acontecem. Se olharmos nos últimos 20 anos desde que a convenção do clima foi criada, o mundo não fez o suficiente. E as emissões ainda estão aumentando. Então, não tenho muita certeza se o que tivemos até agora foi realmente muito efetivo. E talvez o que precisamos agora é de algo mais efetivo, que vá de encontro ao objetivo de evitar interferência antropocêntrica (humana) no sistema climático. Que é o objetivo principal da Convenção do Clima da ONU.

Em 2009, pouco antes da COP-15, tivemos o episódio que ficou conhecido como Climategate, quando e-mails de cientistas foram expostos. O senhor tem medo de hackers ou grampos telefônicos?
Tudo isso é crime, e uma pessoa não pode ficar com medo e deixar de fazer o que se espera dela. Temos de continuar nosso trabalho e é isso que estamos tentando fazer.

Mas o senhor recebe ameaças?
Sim, mas eu prefiro não falar sobre elas.

O que o IPCC aprendeu com o erro do Himalaia?
Em primeiro lugar, deixe-me colocar esse erro em perspectiva. Tínhamos 3 mil páginas de relatório e milhares de dados. E uma única informação em que cometemos o erro, de que as geleiras do Himalaia desapareceriam em 2035, não estava no sumário técnico, no sumário para os tomadores de decisão nem no relatório síntese. Estava apenas no relatório principal, que é essencialmente científico, não é para os tomadores de decisão. Então, de nenhuma maneira estávamos tentando chamar a atenção dos tomadores de decisão para esse dado errado. Francamente, não sabíamos do erro. Agora temos procedimentos mais fortes, mais passos a seguir, um protocolo de correção. Tudo isso vai nos ajudar a lidar com uma situação como essa muito melhor no futuro.

O senhor acha que o trabalho se tornando mais burocrático, com mais revisões e correções, pode afastar os cientistas do IPCC?
Nossa instituição tem uma responsabilidade com a sociedade. Então, se nós não temos um sistema em que um erro possa ser corrigido, então claramente há um déficit. É nossa responsabilidade buscar um sistema em que erros, uma vez que apareçam, possam ser investigados e depois corrigidos. E não tínhamos isso no passado.

E os cientistas continuam querendo se ligar ao IPCC, é importante para suas carreiras?
Absolutamente. Não sei a respeito das carreiras, mas com certeza pelo senso de orgulho profissional. Para o 5.º Relatório do IPCC tivemos um número recorde de nomeações. Cerca de 3 mil nomeações, das quais elegemos 831. O número foi pelo menos 50% maior do que tivemos no 4.º relatório. E isso mostra que a comunidade científica se entusiasma em trabalhar com o IPCC.

Acha que a crise econômica está impactando as negociações e as ações dos governos?
Eu acho que sim. Mas é por isso que eu acho que a primazia da ciência deve ser mantida. Vamos encarar a questão: a crise econômica deve ser resolvida em dois, três, quatro anos, algo assim. Mas o problema das mudanças climáticas está aqui para todo o sempre. Então, não podemos nos cegar por considerações de curto prazo.

O que o senhor espera da Rio+20?
O que vai ser a reunião é difícil de prever. Mas eu espero que marque um ponto de virada em nossa forma de pensar e em nossas atitudes. Já é hora de olhar para as implicações no longo prazo do que estamos fazendo e tomar algumas decisões. Eu espero a Rio+20 marque uma mudança na forma de pensar da raça humana.

Secretária da ONU diz que ações são respostas à ciência – A secretária executiva da Convenção do Clima da ONU, Christiana Figueres, negou ao Estado que a ciência não ocupe posição central nas negociações. “Se a ciência não dissesse que temos um problema, não estaríamos aqui. A convenção existe precisamente em resposta à ciência e a convenção sempre está atenta aos seus progressos.” Segundo ela, a convenção acompanhará o 5º Relatório do IPCC, a ser publicado em 2013 e 2014.

US will not air climate change episode of Frozen Planet (New Statesman)

Posted by Samira Shackle – 17 November 2011 13:38

BBC defends decision to give world TV channels the option of dropping the final episode of David Attenborough’s series.

An episode of David Attenborough’s Frozen Planet series that looks at climate change will not be aired in the US, where many are sceptical about global warming.

Seven episodes of the multi-million-pound nature documentary series will be aired in Britain. However, the series has been sold to 30 world TV networks as a package of only six episodes. These networks then have the option of buying the seventh “companion” episode — which explores the effect man is having on the natural world — as well as behind the scenes footage.

The six-episode series has been sold to 30 broadcasters, ten of which have declined to use the climate change episode, “On Thin Ice”, including the US.

In America, the series is being aired by the Discovery channel, which insists that the final episode has been dropped because of a “scheduling issue”.

Regardless of their reasoning, environmental campaigners have criticised the BBC’s decision to market the episode separately as “unhelpful”. And it has caused controversy across the board. The Telegraph‘s headline (“BBC drops Frozen Planet’s climate change episode to sell show better abroad”) sums up how the news has been received.

However, the BBC have defended the decision, claiming that it is more to do with a difference in style in this episode than its content. Caroline Torrance, BBC Worldwide’s Director of Programme Investment, wrote in a blog that the first six episodes “have a clear story arc charting a year in our polar regions”, adding:

Although it is filmed by the same team and to the same production standard, this programme is necessarily different in style.

Having a presenter in vision requires many broadcasters to have the programme dubbed, ultimately giving some audiences a very different experience.

Audiences are currently enjoying incredible footage of the natural world; it would be a shame for them to leave without a sense of the danger it faces.

Corporations spending billions to exert ‘undue influence’ to prevent global climate action: report (Canada.com)

BY MIKE DE SOUZA, POSTMEDIA NEWS NOVEMBER 23, 2011

A handful of multinational corporations are “exerting undue influence” on the political process in Canada, the U.S. and other key nations to delay international action on climate change, alleges a new report released Tuesday by Greenpeace International.

The report documents a series of alleged lobbying and marketing efforts led by major corporations and industry associations, representing oil and gas companies as well as other major sources of pollution in Canada, the U.S., Europe and South Africa, which is hosting an international climate-change summit that begins next Monday.

South of Canada’s borders, industry stakeholders are investing about $3.5 billion per year to lobby the U.S. government on a variety of issues, as well as financing American politicians who “deny” scientific evidence linking human activity to dangerous changes in the atmosphere that contribute to global warming, estimates the report, titled: Who’s holding us back? How carbon intensive industry is preventing effective climate legislation.

“Carbon-intensive corporations and their networks of trade associations are blocking policies that aim to transition our societies into green, sustainable, low risk economies,” said the report, authored by Greenpeace staff from around the world, based on national lobbying registries and other public records from government and industry.

“These polluting corporations often exert their influence behind the scenes, employing a variety of techniques, including using trade associations and think-tanks as front groups; confusing the public through climate denial or advertising campaigns; making corporate political donations; as well as making use of the ‘revolving door’ between public servants and carbon-intensive corporations.”

The report raises questions about activities of energy industry companies including Shell, Koch Industries and Eskom, as well as BASF — a chemical products company, BHP Billiton — a mining company, and ArcelorMittal, a steel company created from a merger that followed the takeover of Canadian-based Dofasco by Europe-based Arcelor.

Most nations at the upcoming international summit in Durban, South Africa, have publicly said they hope to extend targets to reduce pollution under the Kyoto Protocol, the world’s only legally-binding treaty on global warming. But Canada, along with Japan and Russia, has openly indicated that it plans to walk away from the agreement which set targets for developed nations between 2008 and 2012 as a first step toward stabilizing greenhouse gas emissions in the atmosphere.

“Canada goes to Durban with a number of countries sharing the same objectives and that is to put Kyoto behind us and to encourage all nations and all major emitting countries to embrace a new agreement to reduce greenhouse gas in a material way,” Environment Minister Peter Kent said Tuesday in the House of Commons in response to questions from NDP environment critic Megan Leslie.

Representatives of the Canadian Association of Petroleum Producers, one of the lobby groups singled out in the report, have explained it supports balanced climate and energy policies that allow for growth of all energy sources to meet rising demands in the decades to come. But meantime, the association says its member companies are already adapting to new policies and pollution taxes from jurisdictions such as Alberta and British Columbia, while investing in new technologies to prepare for stronger standards in the future.

Natural deposits in Western Canada, also known as the oilsands, are believed to contain one of the largest reserves of oil in the world, but they require large amounts of energy, land and water to extract the fuel from the ground, with an annual global warming footprint that has almost tripled since 1990. The annual greenhouse gas emissions from this sector are now greater than those of all cars on Canadian roads and almost as much as the pollution from all light-duty trucks or sport utility vehicles driven in Canada.

The Canadian lobby group has opposed policies in jurisdictions such as the U.S. and the European Union that would discourage consumption of fuel derived from the oilsands or other sources that have a heavier footprint than conventional sources of oil.

The report highlights say the federal and Alberta governments have also been partners in a taxpayer-funded “advocacy strategy” led by Canada’s Foreign Affairs Department to fight international climate-change policies and “promote the interests of oil companies.”

Prime Minister Stephen Harper’s government and its Liberal predecessors have repeatedly pledged to regulate pollution from the industry without following through on their commitments. Kent also promised to introduce a plan to tackle emissions from the oilsands sector this year, but later retreated on the commitment.

“The reason that Canada has actually made it in here (the report), is because the Harper government has acted with and on behalf of tarsands companies to undermine international action on climate change,” said Greenpeace Canada climate and energy campaigner Keith Stewart. “When we look at this globally, if we’re serious about avoiding climate catastrophe, we can’t afford to let the Harper government and the tarsands industry grow the markets of dirty oil at the expense of cleaner alternatives.”

The report highlighted a pattern of industry lobby groups and chambers of commerce running advertising campaigns against any proposals to tackle climate change by warning people in the general public that their respective countries were acting alone and would kill jobs by adopting measures to reduce pollution. It also noted that some companies, which claim to defend action on climate change, are actively supporting industry associations that are seeking to undermine progress on the issue.

The Greenpeace report also coincides with the mysterious release on Tuesday of emails from a British-based climate research unit that was at the heart of controversy prior to a 2009 climate change summit when the stolen correspondence was used by climate skeptics to allege an international conspiracy by scientists to mislead the planet about the consequences of rising greenhouse gas emissions.

A series of independent inquiries have dismissed the conspiracy theories and cleared the scientists involved of any wrongdoing, but those responsible for stealing the emails were never caught.

SUMMARY OF THE 34TH SESSION OF THE INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (Earth Negotiations Bulletin)

Volume 12 Number 522 – Monday, 21 November 2011

The 34th session of the Intergovernmental Panel on Climate Change (IPCC) was held from 18-19 November 2011 in Kampala, Uganda. The session was attended by more than two hundred participants, including representatives from governments, the United Nations, and intergovernmental and observer organizations. Participants focused primarily on the workstreams resulting from the consideration of the InterAcademy Council (IAC) Review of the IPCC processes and procedures, namely those on: procedures, conflict of interest policy, and communications strategy.

The Panel adopted the revised Procedures for the Preparation, Review, Acceptance, Adoption, Approval and Publication of IPCC Reports, as well as the Implementation Procedures and Disclosure Form for the Conflict of Interest Policy. The Panel also formally accepted the Summary for Policy Makers (SPM) of the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX), approved by WGs I and II at their joint meeting from 14-17 November 2011. Delegates also addressed issues such as the programme and budget, matters related to other international bodies, and progress reports.

A BRIEF HISTORY OF THE IPCC

The IPCC was established in 1988 by the World Meteorological Organization (WMO) and the UN Environment Programme (UNEP). Its purpose is to assess scientific, technical and socio-economic information relevant to understanding the risks associated with human-induced climate change, its potential impacts, and options for adaptation and mitigation. The IPCC does not undertake new research, nor does it monitor climate-related data, but it conducts assessments on the basis of published and peer-reviewed scientific and technical literature.

The IPCC has three Working Groups (WGs): WGI addresses the scientific aspects of the climate system and climate change; WGII addresses the vulnerability of socio-economic and natural systems to climate change, impacts of climate change and adaptation options; and WGIII addresses options for limiting greenhouse gas emissions and mitigating climate change. Each WG has two Co-Chairs and six Vice-Chairs, except WGIII, which for the Fifth Assessment cycle has three Co-Chairs. The Co-Chairs guide the WGs in fulfilling the mandates given to them by the Panel and are assisted in this task by Technical Support Units (TSUs).

The IPCC also has a Task Force on National Greenhouse Gas Inventories (TFI). TFI oversees the IPCC National Greenhouse Gas Inventories Programme, which aims to develop and refine an internationally agreed methodology and software for the calculation and reporting of national greenhouse gas emissions and removals, and to encourage the use of this methodology by parties to the United Nations Framework Convention on Climate Change (UNFCCC). The Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) is an entity set up to address WG needs for data, especially WGII and WGIII. The TGICA facilitates distribution and application of climate change related data and scenarios, and oversees a Data Distribution Centre, which provides data sets, scenarios of climate change and other environmental and socio-economic conditions, and other materials.

The IPCC Bureau is elected by the Panel for the duration of the preparation of an IPCC assessment report (approximately six years). Its role is to assist the IPCC Chair in planning, coordinating and monitoring the work of the IPCC. The Bureau is composed of climate change experts representing all regions. Currently, the Bureau comprises 31 members: the Chair of the IPCC, the Co-Chairs of the three WGs and the Bureau of the TFI (TFB), the IPCC Vice-Chairs, and the Vice-Chairs of the three WGs. The IPCC Secretariat is located in Geneva, Switzerland, and is hosted by the WMO.

IPCC PRODUCTS: Since its inception, the IPCC has prepared a series of comprehensive assessments, special reports and technical papers that provide scientific information on climate change to the international community and are subject to extensive review by experts and governments.

The IPCC has so far undertaken four comprehensive assessments of climate change, each credited with playing a key role in advancing negotiations under the UNFCCC: the First Assessment Report was completed in 1990; the Second Assessment Report in 1995; the Third Assessment Report in 2001; and the Fourth Assessment Report (AR4) in 2007. At its 28th session in 2008, the IPCC decided to undertake a Fifth Assessment Report (AR5) to be completed in 2014.

The latest Assessment Reports are structured into three volumes, one for each WG. Each volume is comprised of a SPM, a Technical Summary and an underlying assessment report. All assessment sections of the reports undergo a thorough review process, which takes place in three stages: a first review by experts; a second review by experts and governments; and a third review by governments. Each SPM is approved line-by-line by each respective WG. The Assessment Report also includes a Synthesis Report (SYR), highlighting the most relevant aspects of the three WG reports, and a SPM of the SYR, which is approved line-by-line by the Panel. More than 450 lead authors, 800 contributing authors, 2500 expert reviewers and 130 governments participated in the elaboration of the AR4.

In addition to the comprehensive assessments, the IPCC produces special reports, methodology reports and technical papers, focusing on specific issues related to climate change. Special reports prepared by the IPCC include: Aviation and the Global Atmosphere (1999); Land Use, Land-use Change and Forestry (2000); Methodological and Technical Issues in Technology Transfer (2000); Safeguarding the Ozone Layer and the Global Climate System (2005); Carbon Dioxide Capture and Storage (2005); Renewable Energy Sources and Climate Change Mitigation (SRREN) (2011); and, most recently, the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) (2011). Technical papers have been prepared on Climate Change and Biodiversity (2002) and on Climate Change and Water (2008), among others.

The IPCC also produces methodology reports or guidelines to assist countries in reporting on greenhouse gases. The IPCC Guidelines for National Greenhouse Gas Inventories were first released in 1994 and a revised set was completed in 1996. Additional Good Practice Guidance reports were approved by the Panel in 2000 and 2003. The latest version, the IPCC Guidelines on National Greenhouse Gas Inventories, was approved by the Panel in 2006.

For all this work and its efforts to “build up and disseminate greater knowledge about manmade climate change, and to lay the foundations that are needed to counteract such change,” the IPCC was awarded the Nobel Peace Prize, jointly with former US Vice President Al Gore, in December 2007.

IPCC-28: This session was held from 9-10 April 2008, in Budapest, Hungary, with discussions centering on the future of the IPCC, including key aspects of its work programme such as WG structure, main type and timing of future reports, and the future structure of the IPCC Bureau and the TFB. At this session, the IPCC agreed to prepare the AR5 and to retain the current structure of its WGs. In order to enable significant use of new scenarios in the AR5, the Panel requested the Bureau to ensure delivery of the WGI report by early 2013 and completion of the other WG reports and the SYR at the earliest feasible date in 2014. The Panel also agreed to prepare the SRREN Report, to be completed by 2010. Earth Negotiations Bulletin coverage of IPCC 28 can be found at:http://www.iisd.ca/climate/ipcc28

IPCC-29: This session, which commemorated the IPCC’s 20th anniversary, was held from 31 August to 4 September 2008, in Geneva, Switzerland. At this time, the Panel elected the new IPCC Bureau and the TFB, and re-elected Rajendra Pachauri (India) as IPCC Chair. The Panel also continued its discussions on the future of the IPCC and agreed to create a scholarship fund for young climate change scientists from developing countries with the funds from the Nobel Peace Prize. It also asked the Bureau to consider a scoping meeting on the SREX, which took place from 23-26 March 2009 in Oslo, Norway. Earth Negotiations Bulletin coverage of IPCC-29 can be found at: http://www.iisd.ca/climate/ipcc29

IPCC-30: This session was held from 21-23 April 2009 in Antalya, Turkey. At the meeting, the Panel focused mainly on the near-term future of the IPCC and provided guidance for an AR5 scoping meeting, which was held in Venice, Italy, from 13-17 July 2009. The Panel also gathered climate change experts to propose the chapter outlines of WG contributions to the AR5. Earth Negotiations Bulletincoverage of IPCC 30 can be found at: http://www.iisd.ca/climate/ipcc30

IPCC-31: This session was held from 26-29 October 2009 in Bali, Indonesia. Discussions focused on approval of the proposed AR5 chapter outlines developed by participants at the Venice scoping meeting. The Panel also considered progress on the implementation of decisions taken at IPCC 30 regarding the involvement of scientists from developing countries and countries with economies in transition, use of electronic technologies, and the longer-term future of the IPCC. Earth Negotiations Bulletin coverage of IPCC 31 can be found at: http://www.iisd.ca/climate/ipcc31

INTERACADEMY COUNCIL REVIEW: In response to public criticism of the IPCC related to inaccuracies in the AR4 and the Panel’s response, as well as questions about the integrity of some of its members, UN Secretary-General Ban Ki-moon and IPCC Chair Rajendra Pachauri requested the IAC to conduct an independent review of the IPCC processes and procedures and to present recommendations to strengthen the IPCC and ensure the on-going quality of its reports. The IAC presented its results in a report in August 2010. The IAC Review makes recommendations regarding: management structure; a communications strategy, including a plan to respond to crises; transparency, including criteria for selecting participants and the type of scientific and technical information to be assessed; and consistency in how the WGs characterize uncertainty.

IPCC-32: This session, held from 11-14 October 2010 in Busan, Republic of Korea, addressed the recommendations of the IAC Review. The Panel adopted a number of decisions in response to the IAC Review, including on the treatment of grey literature and uncertainty, and on a process to address errors in previous reports. To address recommendations that required further examination, the Panel established task groups on processes and procedures, communications, conflict of interest policy, and management and governance. The Panel also accepted a revised outline for the AR5 SYR. Earth Negotiations Bulletin coverage of IPCC 32 can be found at:http://www.iisd.ca/climate/ipcc32

SRREN: The eleventh session of WGIII met from 5-8 May 2011 in Abu Dhabi, United Arab Emirates, and approved the Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) and its SPM. Discussions focused, among others, on chapters addressing sustainable development, biomass and policy. Key findings of the SRREN include that the technical potential for renewable energies is substantially higher than projected future energy demand, and that renewable energies play a crucial role in all mitigation scenarios.

IPCC-33: The session, held from 10-13 May 2011 in Abu Dhabi, United Arab Emirates, focused primarily on follow-up actions to the IAC Review of the IPCC processes and procedures. The Panel decided to establish an Executive Committee, adopted a Conflict of Interest Policy, and introduced several changes to the rules of procedure. The Panel also endorsed the actions of WGIII in relation to SRREN and its SPM and considered progress on the preparation of the AR5. Earth Negotiations Bulletin coverage of IPCC 33 can be found at: http://www.iisd.ca/vol12/enb12500e.html

SREX: The First joint session of IPCC WGs I and II, which took place on 14-17 November in Kampala, Uganda, accepted the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) and approved its SPM. The SREX addressed the interaction of climatic, environmental and human factors leading to adverse impacts of climate extremes and disasters, options for managing the risks posed by impacts and disasters, and the important role that non-climatic factors play in determining impacts.

IPCC-34 REPORT

IPCC Chair Rajendra Pachauri opened the 34th session of the Intergovernmental Panel on Climate Change on Friday, 18 November 2011, highlighting ongoing work related to the Fifth Assessment Report (AR5) and progress in the implementation of the InterAcademy Council (IAC) recommendations. He also referred to the communications strategy and the need to ensure policy relevance and reach out to policymakers. Pachauri said it was critically important that the results of the Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) and the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) be presented to the United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP) in Durban, South Africa. He emphasized the significance of the meeting being held in Africa, given the findings related to climate change impacts and development challenges in the region, and thanked Uganda for hosting the meeting and Norway for its support.

Norwegian Ambassador Thorbjørn Gaustadsæther highlighted that the SREX is an important tool for understanding, taking actions, and making decisions on managing the risks of extreme events and disasters. He noted that extreme weather events and their negative impacts are apparent everywhere, including in Uganda, for fishermen on the Lake Victoria who experience reduced catch, as well as in his native Norway, which experiences dramatic flooding, shrinking Arctic ice and other events. He said the SREX would be presented to governments at the Durban UNFCCC meeting and would provide a good basis for them to take action. He thanked the Ugandan government for its hospitality and said Norway was pleased to have contributed to the organization of the meeting.

Peter Gilruth, on behalf of UNEP Executive Director Achim Steiner, stressed the potential of the SREX, including as a foundation on which the disaster risk reduction and the climate change communities can build stronger bridges, and as a basis for environment and development work. He noted various UNEP initiatives and assessment reports, including the Programme of Research on Climate Change Vulnerability, Impacts and Adaptation, the fifth Global Environmental Outlook and the Emissions Gap Assessment, and invited delegates to participate in the “Eye on Earth” summit in December to build partnerships on knowledge sharing.

Florin Vladu, on behalf of Christiana Figueres, Executive Secretary of the UNFCCC, updated the plenary on developments in the negotiating process, highlighting the achievements of the Cancun Agreements in establishing an institutional infrastructure, but noting a failure to address the future of the Kyoto Protocol and a mitigation framework. Vladu said that in Durban countries face a challenge to find a viable way forward, but expressed hope that the conference will help build confidence in post-2012 climate finance through clarity on long-term finance and making the Green Climate Fund operational. Vladu highlighted that the UNFCCC process has benefited from an active research dialogue with the IPCC, most recently in the form of a presentation on the SRREN at the Subsidiary Body for Scientific and Technological Advice (SBSTA) session in June 2011. He also noted the special role of the IPCC in the UNFCCC review of the adequacy of the goal of limiting average global temperature below 2 degrees Celsius and the overall progress towards achieving this goal, which is scheduled to commence in 2013. On SREX, he said the report would contribute both to the work of SBSTA, and Adaptation Framework, and work programme on loss and damage, once those become operational.

Noting that this has been a transformative year for the IPCC, Jeremiah Lengoasa, on behalf of World Meteorological Organization (WMO) Secretary-General Michel Jarraud, reaffirmed support for the work of the Panel and emphasized the importance of the IPCC’s work and procedures remaining relevant and timely. He welcomed the AR5 preparations moving ahead as scheduled and stressed that the AR5 will provide a strong basis for decision-making, including in relation to water resources, agriculture and food security. He also highlighted the role of the WMO Global Framework for Climate Services, to be launched in the near future, to further assist in decision-making.

Maria Mutagamba, Minister for Water and Environment, Uganda, expressed warm greetings from the people of Uganda and welcomed delegates to the country traditionally known as the Pearl of Africa. She said that it is with great pride that Uganda continues to participate actively in the work of the IPCC and hosts this meeting, and thanked Norway, which co-funded the session. She said that Uganda has already started experiencing extreme weather events attributed to climate change such as severe droughts, floods and increased frequency of landslides. Highlighting the inevitability of climate change, she noted that her country has adaptation policies in place. On mitigation, she underlined Uganda’s early efforts under the Clean Development Mechanism. She further noted the need to strengthen national meteorological and hydrological services in developing countries and thus expressed support for the WMO Global Framework for Climate Services. She also suggested the IPCC continue to consider the role of indigenous knowledge in areas where peer-reviewed literature is unavailable or insufficient as well as issues of technology transfer to developing countries and dissemination of information.

The Panel then observed a minute of silence for the untimely and sad passing away of Mama Konate, UNFCCC SBSTA Chair and IPCC colleague.

APPROVAL OF THE DRAFT REPORT OF THE 33RD SESSION

The draft report of IPCC-33 (IPCC-XXXIV/Doc. 2, Rev.1) was adopted on Friday morning with a minor editorial amendment. Belgium noted the lack of reference in the meeting minutes to the Expert Meeting on Geoengineering and the participation of media representatives in at that meeting.

SPECIAL REPORT ON EXTREME EVENTS AND DISASTERS

This issue (IPCC-XXXIV/Doc. 21) was taken up by the plenary on Friday morning. The IPCC plenary formally accepted the actions taken at the Joint Session of Working Groups I and II on the SREX, including approving its Summary for Policy Makers (SPM). Underscoring the importance and usefulness of the SREX, Austria said that, among others, this landmark report introduces terminology to be understood both by the risk management and the climate change community, identifies a range of practices and options to reduce risk, and provides clarity on what the most vulnerable sectors, groups and areas are, making it of tremendous use for taking appropriate actions.

PREPARATION OF THE FIFTH ASSESSMENT REPORT (AR5)

The item (IPCC-XXXIV/Doc. 5) was presented to the plenary on Friday afternoon. Chair Pachauri recalled that the Panel had issued a clear mandate to start very early with the AR5 Synthesis Report (SYR), and Leo Meyer, Head of the SYR Technical Support Unit (TSU), reported on process and management issues related to the SYR (IPCC-XXXIV/Doc. 5). Meyer noted, inter alia: the inclusion of the IPCC Vice-Chairs on the SYR writing team since they have responsibilities related to cross-cutting issues; the possibility of a workshop on UNFCCC Article 2, which could feed into the UNFCCC review of the adequacy of the Convention’s ultimate goal; and the suggestion to reduce the time of eight weeks allowed for government comments on the final draft of the SPM to six weeks given the compressed timeline of the SYR.

On the time frame, the US suggested, and the Panel agreed, to seven weeks instead of the six weeks proposed for government comments.

With regard to a possible workshop on UNFCCC Article 2, Chair Pachauri suggested inviting general comments by governments. Emphasizing the importance of the IPCC retaining distance from the policy process, the US, supported by New Zealand, Canada, Saudi Arabia and others, opposed the suggestion. Saudi Arabia underscored that the issue of Article 2 is very sensitive. The Panel agreed to have the Bureau consider the matter at its next meeting.

REVIEW OF THE IPCC PROCESSES AND PROCEDURES

CONFLICT OF INTEREST POLICY: This issue (IPCC-XXXIV/Doc. 8, Rev. 1) was first addressed in the plenary on Friday and then in several meetings of a contact group co-chaired by Andrej Kranjc (Slovenia) and Jongikhaya Witi (South Africa), with Samuel Duffett (UK) as Rapporteur. The workstream on the Conflict of Interest (COI) Policy arose in response to the recommendations made in the IAC Review to develop and adopt a rigorous COI Policy. At IPCC-33 delegates adopted a COI Policy and extended the mandate of the Task Group on COI in order to develop proposals for annexes to the COI Policy covering Implementation Procedures and the Disclosure Form.

Contact group discussions focused on the draft Implementation Procedures prepared by the Task Group. During the group’s first meeting, Co-Chair Kranjc noted that the Task Group held four teleconferences in between sessions and that the WGs already have experience applying the COI Policy on an interim basis. Rapporteur Duffett then explained the proposed decision-making process on COI, noting there would be different procedures for Bureaux members and non-Bureaux members.

The discussions centered on several issues, including: which body determines whether an individual has a COI; the role of the COI Expert Advisory Group; which body is responsible for the final decision in cases of COI; cases of tolerance of COI for non-Bureaux members; and principles for considering COI issues.

On a body to determine whether an individual has a COI, the proposal of the Task Group was to form a special committee comprised of representatives from each of the six WMO regional groups. Some participants noted that implementation of COI policies is a relatively simple and technical procedure and in most cases there is no COI, so it would be an additional burden to establish a new committee and conduct elections for its members. In this regard, they suggested making use of existing bodies and assigning this function to the Executive Committee. They also suggested that the Executive Committee members would be the ones most interested in maintaining the integrity of the IPCC. Others expressed concern about Bureaux members who are part of the Executive Committee making decisions on their own COI. A compromise was reached on establishing a COI Committee composed of voting members of the Executive Committee and representatives of WMO and UNEP, with a recusal clause.

Delegates also developed principles for considering COI issues, introducing those in relation to exploring options for resolution of COI and an appeals procedure. The group added a provision requiring members of bodies involved in considering COI issues to recuse themselves from a discussion on their own COI.

The Task Group proposed that the Expert Advisory Group, which would be comprised of three representatives from WMO and UNEP, review COI forms of Bureaux nominees. However, some expressed a concern about this approach and a change was introduced that the COI Committee consults the Expert Advisory Group when it deems necessary.

Further discussion took place on which body would be responsible for a final decision on COI. An opinion was expressed that all final decisions should be made in plenary; however, others raised concerns about maintaining the confidentiality of personal information in that case. The contact group elaborated on an appeals procedure, assigning a function to the IPCC Bureau to review a COI determination on request by the individual in question.

On COI in relation to non-Bureaux members, several supported some flexibility in this regard as there are too few experts in some areas and those are often involved with industries or organizations. Delegates developed the relevant procedures on the tolerance of COI in such cases.

In the final plenary, the Panel adopted the Implementation Procedures and Disclosure Form for the COI Policy with minor editorial corrections. Chair Pachauri said COI was clearly one of the trickiest and most complex issues to address in relation to the IAC Review.

The US expressed its satisfaction with an “excellent” outcome on COI, in particular regarding the creation of a body that will implement the COI Policy effectively and very soon, composed of those with a strong interest in ensuring the integrity of its outcomes.

Canada noted that the contact group discussions were exceedingly positive and that the Implementation Procedures for the COI Policy will provide an effective process to promote transparency. The Netherlands underlined the enormous importance of the documents on COI for the transparency and integrity of the Panel, and its acceptance by the outside world. Thanking all members of the Task Group, Australia congratulated the plenary on a “groundbreaking” COI mechanism for many international organizations, both in substance and in the procedure of how it was developed.

Secretary Christ asked the plenary how the set of documents on COI should be integrated into IPCC regulations and suggested a paragraph be added that states these documents constitute an appendix to the Principles Governing the IPCC Work. To this, the US replied that more consideration is needed before the documents are elevated to the level of principles and suggested leaving them as standalone documents. The Panel agreed to the suggestion.

Final Decision: In its decision, the Panel, inter alia:

adopts the COI Implementation Procedures and decides that the Procedures will apply to individuals who are subject to the COI Policy;
decides to establish a COI Committee comprising all elected members of the Executive Committee and two additional members with appropriate legal expertise from UNEP and WMO, appointed by those organizations;
decides to establish an Expert Advisory Group on COI and invites the Secretary-General of WMO and the Executive Director of UNEP to select members of the COI Expert Advisory Group and to facilitate the establishment of the COI committee as soon as possible;
notes that the WG and Task Force Bureaux have adopted interim arrangements for dealing with COI issues and that those arrangements are broadly consistent with the COI Policy;
decides that, to ensure a smooth transition, the existing interim arrangements will continue to operate, with respect to individuals who are not Bureau members until the Executive Committee decides that the implementation procedures apply to those individuals;
requests IPCC and TFI Bureaux members to submit a COI Form to the Secretariat within three months;
decides to receive a report on the operation of the COI Expert Advisory Group and the COI Committee within twelve months of their establishment and to review their operations, as appropriate, within twelve months after the next Bureaux election(s); and
notes that the COI Committee will develop its own methods of working and will apply those on an interim basis pending approval by the Panel, and decides that the COI Committee should submit its methods of working to the Panel within twelve months of its establishment.
Implementation Procedures: The Procedures address the following:

The overall purpose of the Implementation Procedures is to ensure that COIs are identified, communicated to the relevant parties and manage to avoid any adverse impact of IPCC balance, products and processes, and also to protect the individual, the IPCC and the public interest.
In their scope, the Implementation Procedures apply to all COIs and all individuals defined in the COI Policy, and compliance with the COI Policy and the Procedures is mandatory.
The Implementation Procedures further set out the review process on COI for IPCC and Task Force Bureaux members prior to and after their appointment. According to this process, the COI Disclosure Forms for all nominees should be submitted to the Secretariat to be reviewed by a COI Committee. The COI Committee may request advice from the Expert Advisory Group on COI. If the COI Committee determines that a nominee has a COI that cannot be resolved, the individual will not be eligible for election to the Bureau.
The Implementation Procedures also outline the review process for Coordinating Lead Authors, Lead Authors, Review Editors and TSUs prior to and after their appointment. In this case, Disclosure Forms are submitted to relevant TSUs and reviewed by WG or Task Force Bureaux. The document defines exceptional circumstances in which a COI in relation to non-Bureaux members may be tolerated, that is when an individual can provide a unique contribution and when a COI can be managed. Such cases should be disclosed. The document also outlines the process to deal with a COI after the appointment of non-Bureaux members, including updating information, review and an appeal procedure.
The Implementation Procedures set out principles for considering COI issues that are applied to all bodies involved in advising on and deciding COI issues. In this regard, they require those bodies to consult the relevant individual regarding potential COIs and explore the resolution options as well as provide for an appeal procedure. The document also requires members of the bodies involved in consideration of COI issues to recuse themselves when being a subject of consideration.
The Implementation Procedures further contain provisions on processing and storage of information to ensure confidentiality of submitted information.
The document further sets out the composition and functions of the COI Committee and Expert Advisory Group on COI.
Annex B to the Implementation Procedures also contains a COI Disclosure Form.
PROCEDURES: This issue (IPCC-XXXIV/Doc. 9, Add. 1) was first introduced in the plenary on Friday and then taken up by a contact group co-chaired by Eduardo Calvo (Peru) and Øyvind Christophersen (Norway), with Arthur Petersen (Netherlands) as Rapporteur. Work centered on the finalization of revisions to the Appendix A to the Principles Governing IPCC Work: Procedures for the Preparation, Review, Acceptance, Adoption, Approval and Publication of IPCC Reports, which started at IPCC-32. The Panel adopted the revised Procedures Appendix in plenary on Saturday, completing the work of the Task Group on Procedures.

Discussions in the contact group centered on the production and treatment of guidance material, the selection of participants to IPCC workshops and expert meetings, matters related to the transparency, quality and efficiency of the review process, anonymous expert review, and SPM approval sessions.

On guidance material, Belgium and others called for stating that guidance material needs to be taken into account in the preparation of the reports in addition to stating what guidance material is, while others cautioned against excessively normative language. The group agreed leave the text as is.

On the selection of participants to IPCC workshops and expert meetings, the group addressed text related to the distinction between these two types of meetings.

On matters related to the transparency, quality and efficiency of the review process, the group considered the Revised Guidance Note on the Role of Review Editors (IPCC-XXXIV/Doc. 9, Add.1) prepared by the WG and TFI Bureaux. The group also addressed the current practice of expanding the number of Review Editors per chapter. After some discussion, the group agreed that there was a need to limit the number of Review Editors to four per chapter.

On text related to open invitations for expert reviewers, recommendations were made to circulate second in addition to First Order Draft Reports by WG/TFB Co-Chairs for review. In relation to inviting as wide a group of experts as possible, Review Editors were added to a list of potentially nominated experts. Text was also added on notifying Government Focal Points when this process starts.

On anonymous expert review, the group discussed the need to ensure the appropriate flexibility and agreed to add text that clarifies that the procedures do not prescribe WGs and the TFI to use either anonymous or named expert reviews. In order to document past experience with anonymous expert reviews by WGIII and the TFI during the AR4, the group agreed to include the Note by the Task Group on Procedures on IPCC Anonymous Expert Review: Past experiences and arguments in favor or against (Appendix 3 of IPCC-XXXIV/Doc. 9) in an annex to the Report of IPCC-34.

On the process for the SPM approval, the group addressed text on the process for sending government comments to the Second Order Draft prior to the plenary approval session of the SPM, bringing the procedures in line with current practice.

During the final plenary, Austria noted that, although important progress was made, there is a need to further strengthen the Procedures, in particular related to the calibrated uncertainty language of assessments, to increase transparency and traceability of the decisions of authors so these can be understood in the future. He also proposed further addressing the management and working rules for the writing teams so they are the same across WGs. With regard to calibrated language, New Zealand drew attention to the existing Guidance Paper on Uncertainties and cautioned against having the Panel decide on this, stressing that this should be the province of the WGs.

The European Union (EU) asked for clarification on whether participating organizations are also considered in the round of comments by governments for SPM approval. Co-Chair Christophersen responded that this was not brought up or considered by the group. The EU noted that it would be useful to introduce this in the future given the EU’s particular character. Australia proposed, and the Panel agreed, to record the EU’s concern in the minutes of the meeting along with Austria’s suggestion.

Final Decision: The decision on Procedures addresses the following:

On the IPCC guidance material, the Panel decides that guidance material is a category of IPCC supporting material aimed to guide and assist in the preparation of IPCC reports and Technical Papers. The Panel also clarifies who is responsible and who may commission guidance material.
On selection of participants to IPCC Workshops and Expert Meetings, the Panel elaborates on the distinction between these two types of meetings, including their composition, and establishes that the WG/TFI Bureaux or the IPCC Chair will report to the IPCC Bureau and Panel on the process of selection of participants, including a description of how the selection criteria have been applied.
On matters related to transparency, quality and efficiency of the review process, the IPCC welcomes the revised Guidance Note on Review Editors and finds that the recommendations of the IAC on the Review Editors have been taken adequately into account. The Panel also encourages the implementation of this revised Guidance Note in the AR5 and invites the WG Co-Chairs to monitor progress in their WG progress reports. In addition, the Panel decides that to provide a balanced and complete assessment of current information, each WG/TFI Bureau should normally select two to four Review Editors per chapter and per technical summary of each Report. Furthermore, it decides that the WG/TFI Bureaux shall seek the participation of reviewers encompassing the range of scientific, technical and socio-economic views, expertise, and geographical representation, and shall actively undertake to promote and invite as wide a range of experts as possible.
On anonymous expert review, the Panel decides: not to amend the IPCC Procedures; not to preclude a different approach in the future; and to include the Note by the Task Group on Procedures on IPCC Anonymous Expert Review: Past experiences and arguments in favor or against (Appendix 3 of IPCC-XXXIV/Doc. 9) in an annex to the Report of IPCC-34.
On the process for the SPM approval, the Panel specifies the process for governments submitting written comments prior to the plenary approval session.
GOVERNANCE AND MANAGEMENT: This item (IPCC-XXXIV/Doc. 19) was taken up in the opening plenary on Friday. IPCC Chair Pachauri explained that both Co-Chairs of the Task Group on Governance and Management, David Warrilow (UK) and Taha Zatari (Saudi Arabia) were unable to come to Kampala, and that Task Group Co-Chair Warrilow suggested postponing the consideration of the matter until IPCC-35 and proposed holding IPCC-35 in the middle of 2012 rather than in the second half of the year. The UK explained that this will provide for a prompt response to the IAC recommendations and will allow moving forward with the AR5. The UK also proposed that if holding an earlier session is not possible, two sessions could be held next year instead of one. Several countries highlighted that an earlier meeting should not coincide with preparatory meetings for the United Nations Conference on Sustainable Development (Rio+20) and the Conference itself.

Delegates agreed to postpone the consideration of the item until IPCC-35.

COMMUNICATIONS STRATEGY: This item (IPCC-XXXIV/Doc. 20) was addressed in plenary on Friday. Secretary Christ recalled that IPCC-33 agreed on guidance on a communications strategy and requested the Secretariat to elaborate on the strategy according to that guidance. She noted delays with hiring a senior communications specialist who will not be on board for several months and in this context explained that the Secretariat asked its long-term consultant, Charlie Methven, to help prepare the draft communications strategy in order to respond to the plenary’s request.

Methven then elaborated on the main points of the proposed strategy. Highlighting the unique challenges the IPCC faces, he underlined that the future communications system should be a resource rather than a typical corporate structure. At the same time, he said, it should provide a central communication function and a stronger link between various elements of the IPCC, including the WGs and their TSUs. Noting the already existing ad hoc support on communications across WGs, Methven said these practices should be incorporated to make for a more accountable and coherent structure. He also mentioned that the proposed strategy is achievable within the current level of funding.

Chair Pachauri then requested guidance from the plenary on major pillars of the draft strategy.

Many, including New Zealand, US, Austria and Japan, expressed a deep concern about the delay with hiring a senior communications specialist who should be involved in the development of the strategy. Chair Pachauri explained that the hiring process is conducted according to WMO procedures but an individual had been selected and the discussion is now on a compensation package. He noted that this person cannot start immediately after accepting the offer, and that the selected candidate is not aware of the IPCC process sufficiently to actively contribute to its communications strategy.

Referring to the unique nature of the IPCC, the US highlighted the important role of WG Co-Chairs in communication of relevant products and that the proposed communications structure should not be independent from the WGs. He highlighted in this regard that a senior communication specialist should be facilitative in nature and expressed concern that the Executive Committee had no interaction with candidates for this role. Pachauri explained it was difficult to engage all members of the Executive Committee and that some of them were involved in developing the draft communications strategy.

Austria suggested preparing a Panel’s letter to WMO highlighting the urgency of hiring a communications person for the IPCC. He also suggested there should be a role for governments in the communications strategy, especially when it comes to regional matters. Switzerland underlined the importance of scientific integrity in the communication of the IPCC’s work, which often means “sticking literally to what has been said.” Australia proposed that a strategy should be forward-looking and contain a clear set of communications objectives: what to communicate, to whom and how. Several delegates suggested the document be forwarded to the full Executive Committee and Bureau for discussion.

Pachauri concluded that the draft communications strategy would now be discussed by a small group comprising representatives of the WGs, TFI, Secretariat and consultant Methven before being forwarded to the Executive Committee, Bureau and eventually the plenary.

In the final plenary on Saturday, Belgium recalled its proposal to re-establish a Task Force on Outreach and Communications Strategy, noting that such a Task Force had existed but disappeared when Pachauri became Chair, and to collect written comments by governments to advance the issue. Chair Pachauri supported the proposal and suggested Belgium submit it in written form. On a request for clarification by IPCC Vice-Chair Jean-Pascal van Ypersele, Chair Pachauri confirmed agreement at the Executive Committee meeting to have one of the IPCC Vice-Chairs involved in the group in charge of formulating the communications strategy.

The UK proposed, and the Panel agreed, to circulate the new draft communications strategy for comments and revision before the next session. Chair Pachauri said the Executive Committee will come up with a timetable to do so.

MATTERS RELATED TO UNFCCC AND OTHER INTERNATIONAL BODIES

During the opening plenary session, Chair Pachauri informed the Panel that, in contrast to all previous occasions when the IPCC had addressed the UNFCCC COP in plenary, he had now been asked to only present at SBSTA in Durban. He emphasized that this was an issue of institutions, not of personalities. Many countries expressed their disappointment and underscored the importance of conveying the IPCC’s findings to the COP directly, possibly also at the high-level segment. South Africa noted the concerns expressed on the participation of the IPCC at Durban and assured that the matter would receive proper attention by the upcoming COP Presidency.

A drafting group prepared a letter to the UNFCCC, which was distributed to the Panel for approval. The letter, addressed to the UNFCCC Executive Secretary, expressed the Panel’s disappointment and noted the inappropriateness of the decision, underscoring the strategic importance of having the IPCC address the UNFCCC at the COP level as has been the case since the first COP. The letter called for conveying the message to the current and upcoming COP Presidencies. The US, Saudi Arabia and New Zealand called for reflecting on the wisdom of this mode of communication and proposed Chair Pachauri speak again informally to the UNFCCC Executive Secretary on this matter.

On Saturday morning, Chair Pachauri informed the Panel that, after further communication, the UNFCCC Executive Secretary had written to say that she had consulted with the South African delegation and that, although the opening session of UNFCCC COP 17 will be more of a ceremonial nature, the IPCC would be invited to address the COP on Wednesday, 30 November, when it takes up substantive matters.

RULES OF PROCEDURE FOR THE ELECTION OF THE IPCC BUREAU AND ANY TASK FORCE BUREAU

In plenary on Saturday, Secretary Christ invited the Panel to provide guidance on how provisions arising from the review of IPCC processes and procedures at IPCC-33 and 34 are to be reflected in the revision to Appendix C to the Principles Governing IPCC Work: Rules of Procedure for the Election of the IPCC Bureau and Any Task Force Bureau (IPCC-XXXIV/Doc. 7). New Zealand, with Malaysia and Australia, noted that there was no representative from Region V (South-West Pacific) on the WGIII Bureau, and that the revised text leaves open the possibility that someone from Region V is not on the WGIII Bureau. Australia also highlighted that Region V does not have representation on the Executive Committee and said that these issues should be a high priority for IPCC-36. Secretary Christ said that the Secretariat would distribute a text to governments taking into consideration suggestions from IPCC-33 and 34, and would make this a high priority agenda item for IPCC-36.

IPCC PROGRAMME AND BUDGET AND FINANCIAL PROCEDURES FOR THE IPCC

During Friday’s opening plenary session, Secretary Christ gave an overview of issues related to the IPCC Trust Fund Programme and Budget (IPCC-XXXIV/Doc. 3, Rev.1) and the adoption of the revised “Appendix B to the Principles Governing IPCC Work: Financial procedures for the IPCC” (IPCC-XXXIV/Doc. 4, Corr. 1). She noted the need to address the greater cost of the publication and translation of the SRREN and an additional expert meeting on wetlands by TGICA, and urged resolution on the revised Appendix B in order to allow auditing of IPCC accounts.

The Financial Task Team, co-chaired by IPCC Vice-Chair Ismail A.R. El Gizouli (Sudan) and Nicolas Beriot (France), met to address these issues, convening twice on Friday. On Saturday morning, Co-Chair Beriot presented the deliberations of the Task Team to plenary, noting that the meetings had been well attended. He highlighted changes made to Appendix B, including the addition of a paragraph on the Financial Task Team and the revision of a paragraph that grants authority to the Secretariat to adjust allocations in the event that the IPCC Trust Fund is less than the approved budget. On Appendix B, the WMO and EU queried the implication of the IPCC Trust Fund being administered under International Public Sector Accounting Standards. Secretary Christ clarified that the text was drafted with the WMO legal consul, and expressed hope that in negotiating future agreements with the EU the various financial requirements will be reconciled.

Co-Chair Beriot highlighted two other Financial Task Team recommendations to the Panel in relation to simplifying language on procedural matters in the revised Appendix B no later than IPCC-37 and greater flexibility in financing travel arrangements for experts or members of the Bureau from developing countries. The UK and Austria recommended adding a second plenary session next year in order to have enough time to respond to the IAC Review; however, after further discussion, the Panel agreed that a four-day plenary session would be preferable to two two-day plenary sessions because of both time and resource constraints. New Zealand also suggested that teleconferences can be used for preparation meetings prior the next IPCC session.

Final Decision: In its decision, the Panel, inter alia:

approves the modified 2011 budget with respect to cost-related increases in the translation and publication of the SRREN;
approves the modified 2012 budget, which includes cost-related increases in the preparation of the 2013 IPCC Guidelines on Wetlands;
approves the revised “Appendix B to the Principles Governing IPCC Work: Financial Procedures for the IPCC” (IPCC-XXXIV/Doc. 4, Corr.1) with modifications, which include adding the Financial Task Team and granting authority to the Secretariat to make adjustments to allocations if there is a budget shortfall;
requests the Secretariat simplify language in the revised Appendix B document to improve clarity and readability no later than IPCC-37;
notes the forecast budget for 2013 and the indicative budgets for 2014 and 2015;
urges governments from developed countries to continue providing financial support for travel of experts to IPCC meetings;
requests that countries maintain their contributions in 2011 and 2012 and invites governments, which may be able to do so, to increase their level of contributions to the IPCC Trust Fund or to contribute in case they have not done so; and
endorses the expression of concern regarding the imposition of travel plans and arrangements on some experts or members of the Bureau from developing countries, with little concern to the particular traveler constraints and commitments, and that this be relate to the WMO Secretary-General.
PROGRESS REPORTS

AR5, PROGRESS REPORTS OF WGs I, II AND III: The WG Co-Chairs presented on progress since IPCC-33. WGII Co-Chair Vicente Barros (Argentina) highlighted a range of on-going expert, regional expert and lead author meetings, and Head of WGII TSU Kristie Ebi discussed the draft chapter writing schedule (IPCC-XXXIV/Doc. 10).

Head of WGIII TSU Jan Minx highlighted a range of expert and lead author meetings, and noted changes to the WGIII AR5 schedule and the writing process, which include a review of cross-chapter consistency and a policy to remove inactive authors (IPCC-XXXIV/Doc. 18, Rev.1).

WGI Co-Chair Thomas Stocker discussed a variety of expert meetings, including a Joint Expert Meeting in Lima, Peru, on Geoengineering in June 2011; a second WGI Lead Author meeting held in Brest, France in July 2011, which engaged primarily with cross-chapter issues; and a third Lead Author WGI meeting to be held in Marrakech, Morocco in April 2012. Stocker noted that on 16 December 2011 the First Order Draft of the WGI contribution to the AR5 will become available for an eight-week expert review (IPCC-XXXIV/Doc. 14).

TASK GROUP ON DATA AND SCENARIO SUPPORT FOR IMPACT AND CLIMATE ANALYSIS (TGICA): Due to the absence of TGICA representatives at the meeting, Chair Pachauri referred the plenary to the report of the Task Group (IPCC-XXXIV/Doc. 13).

TASK FORCE ON NATIONAL GREENHOUSE GAS INVENTORIES: TFB Co-Chair Thelma Krug (Brazil) reviewed progress on the 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands (2013 Wetlands Supplement) work programme (IPCC-XXXIV/Doc. 12), and noted that a recent Lead Author meeting in Japan identified the scope and coverage of each chapter and addressed several cross-cutting and interacting issues. A Zero Order Draft is expected to be ready for the first science meeting next year. Co-Chair Krug also highlighted ongoing expert meetings and the success of an open symposium hosted in Japan on 22 August 2011, which aimed to explain the purpose and achievement of the TFI to the public.

SRREN: Head of WGIII TSU Jan Minx introduced this issue (IPCC-XXXIV/Doc. 17), noting the outreach activities and publication process timeline.

CROSS-CUTTING THEMES: IPCC Vice-Chair Hoesung Lee (Republic of Korea) discussed the coordination of cross-cutting themes for the AR5 SYR, highlighting that a questionnaire has been prepared and will be sent to the WGs to gain input into how the IPCC Vice-Chairs should best facilitate this process.

IPCC SCHOLARSHIP PROGRAMME: Secretary Christ updated the plenary on progress with the IPCC Scholarship Programme (IPCC-XXXIV/Doc. 16), noting that a total of nine students and researchers from developing countries had been awarded scholarships for the period 2011-2012. She said these included a postgraduate student from Uganda, Jamiat Nanteza, who would be working on climate-related disaster management issues. Secretary Christ stressed that the Secretariat does not have sufficient capacity to continue fundraising activities as there are no specific funds allocated for that work. She said they have been in contact with the UN Foundation that can conduct fundraising in the US but there would be charges involved.

Chair Pachauri underlined that the Programme had been launched with great success, highlighting many applications from the least developed countries, and said guidance is needed from the plenary on how to keep the Programme going. He said given the number of applications, it would be desirable to award at least 40 to 50 scholarships. The US expressed caution regarding this suggestion as it might require a big commitment from the IPCC leadership and Secretariat. He noted that this might also influence how the IPCC is perceived as an assessment body and recalled that when the Programme was launched there was no expectation this would become a major workstream. Belgium expressed interest in the opinion of the Board of Trustees to the Programme.

Chair Pachauri suggested this matter would be discussed at the Bureau meeting, which would provide a paper with a set of options on further direction for the Programme and ways to reduce the workload burden on the Secretariat, to be presented at the next IPCC session.

TIME AND PLACE OF THE NEXT SESSION

Croatia presented its offer to host the next session in Dubrovnik or elsewhere on the Adriatic Coast at a time to be determined.

Recalling the untimely death of SBSTA Chair Mama Konate, IPCC Vice-Chair van Ypersele called for always scheduling a break between any WG or approval session and a plenary session scheduled back-to-back in a way that, insofar as possible, respects participants’ health and wellbeing.

OTHER BUSINESS AND CLOSING OF THE SESSION

Secretary Christ presented on the outcome of the 16th WMO Congress related to the IPCC. She also noted that WMO had not yet decided on the request by IPCC-32 to WMO to not convert their in-cash contribution into in-kind contribution.

Also, Secretary Christ drew attention to a notification from UN Headquarters that the Republic of South Sudan was admitted as a new Member State by the UN General Assembly on 14 July 2011, and that the official name of the Libyan Arab Jamahiriya had been changed to Libya (IPCC-XXXIV/INF.2). The Panel agreed to reflect these changes in the necessary amendments. South Sudan has therefore become a new member of the IPCC, bringing the total of its members to 195 countries.

In his final remarks, Chair Pachauri thanked the government and people of Uganda for their hospitality and excellent organization of the meeting. The session closed at 4:45 pm with a dance performance celebrating Africa by Francis Hayes, conference officer, and local organizers.

A BRIEF ANALYSIS OF IPCC-34

THE CHALLENGE OF CHANGE

It was just a little over a year ago, in October 2010 in Busan, Republic of Korea, when Sir Peter Williams, Vice-President of The Royal Society, UK, presented the major findings and recommendations of the InterAcademy Council (IAC) review of the IPCC processes and procedures. The review was called for by UN Secretary-General Ban Ki-moon and IPCC Chair Rajendra Pachauri to address major criticisms of the IPCC’s work as a result of the discovery of a small number of serious factual errors in the Fourth Assessment Report, allegations of conflicts of interest among those involved in the assessment, and failure to respond adequately to these charges. The IAC report contained recommendations on reforming IPCC’s management and governance, communications strategy, and processes and procedures.

Since then, the IPCC has been busy addressing these recommendations, enacting changes that it hopes will make it more solid and able to weather the intense public scrutiny and attacks by climate change skeptics. At the same time, the IPCC has had to focus on its work on the Fifth Assessment Report (AR5), the cornerstone of its activities. With the IPCC midway through the AR5 cycle, these changes stand to have an impact on the AR5. It is a useful moment in time to begin to assess how much the decisions taken so far have led to substantive changes in the IPCC. This brief analysis will address these questions.

IMPLEMENTING CHANGE

IPCC-34 came at a time when the most difficult decisions in response to the IAC review have already been taken or are well advanced. A variety of organizational, procedural, governance and policy changes were made prior to the Kampala meeting. These include the establishment of an Executive Committee to provide management oversight and address emerging issues on behalf of the Panel between sessions; limiting the terms of office for key Bureau positions; the development of a conflict of interest policy; and increasing transparency in its procedures, including clarifying the selection of participants at expert meetings, authors and others. Other critical issues that have been tackled include a clear policy for correcting errors, strengthening of the review process, and improved guidance for authors, including on evaluation of evidence and consistent treatment of uncertainty.

This session in Kampala concentrated on completing revisions to the Procedures for the IPCC reports. As a result, the Panel finalized its work on the production and treatment of guidance material, the selection of participants to IPCC workshops and expert meetings, matters related to the transparency, quality and efficiency of the review process, anonymous expert review, and approval sessions for Summaries for Policy Makers.

Perhaps most notably, at this session the IPCC agreed on the Implementation Procedures for the Conflict of Interest Policy, which had been developed at IPCC-33. The agreement represented a source of much satisfaction among participants, who feel that the decision taken here allows for prompt implementation and adequate oversight by those who are most interested in maintaining the integrity of the IPCC—that is, the Panel’s Executive Committee. Importantly, implementation of the new comprehensive Conflict of Interest Policy will contribute to increased transparency of the IPCC process—just what the Panel needs to ensure the credibility of its findings.

To the dismay of many, however, the development and implementation of a comprehensive communications strategy is still incomplete. The IPCC has long acknowledged that its outreach and communication is critically deficient and attempts had been initiated to address it in the past, such as the first IPCC communications strategy in 2005-2006, which included the recruitment of a communications officer. The IAC review reinforced this criticism, finding that communication was a major weakness, and recommended the development of a communications strategy, including guidelines on who should speak on behalf of the IPCC. More than a year later, however, the IPCC still has no strategy in place and has not appointed a senior communications officer. In Kampala, the draft communications strategy was met with wide discontent. Many felt a senior communications professional should have been involved in the preparation of the strategy. In addition, others were concerned that the draft strategy had not been discussed by the Executive Committee prior to its presentation before the IPCC. With both the strategy and the appointment delayed, lack of progress on communications elicited much frustration among participants in Kampala and many others in the climate change community alike, and remains a critical gap in the response of the IPCC to the IAC review.

ASSESSING THE QUALITY OF CHANGE

Although it is too early to judge the transformational extent of the changes introduced in the IPCC as a result of the IAC review, it is useful to note some signs of the effects of these changes.

The most evident and welcome changes relate to increased transparency in the IPCC processes and procedures. There is more transparency and consistency over different stages of the assessment process, including the preparation, review, and endorsement of IPCC reports. There is a policy in place to address real or potential conflict of interest among all participants. There is even a better understanding of how the Panel is run, including its management structure, and roles and responsibilities. All these are critically important.

Changes affecting the quality of management and governance are, however, more difficult to see and assess. Having good rules is the start, but adherence and practice is what makes a difference. The fact that the Executive Committee was not consulted or involved in the recruitment of the senior communications professional came as a surprise to many.

One question was how the changes resulting from the IAC review would affect progress on the AR5. In many ways, the IAC review came at a convenient time for the IPCC—having just completed the Fourth Assessment Report and with the bulk of work concentrated on the Working Groups (WGs) as they initiated the AR5. In fact, many of the changes implemented had already been initiated by the WGs, including on a conflict of interest policy, guidance on the treatment of uncertainties and other guidance on procedures. Even the Executive Committee is a formalization of the previous Executive Team. As to the deliverables, the approval in the space of six months of two timely Special Reports –on Renewable Energy Sources and Climate Change Mitigation and on Managing the Risks of Extreme Events and Disasters to Advance Adaptation (SREX) —comes as evidence that the IAC review has not distracted the IPCC from its core business.

As one participant noted, the IAC review was not meant to illicit a revolution but an evolution. The significance of the IPCC reforms will only become apparent as new challenges arise. Assessing the quality of change, that is whether the reforms that the IPCC has already undertaken will actually lead to making the Panel stronger in front of the increased public scrutiny, remains to be seen.

Unfortunately, the lack of a comprehensive communications strategy stands in the way of making the Panel’s reforms and its work evident to the outside world. Communicating the complex science of climate extremes and impacts as presented in the SREX could have already benefited from it. That is why most participants see rapid progress on a communications strategy as vital to ensure success in the implementation of the IPCC changes. While progress on the AR5 is going well, the impact of the IPCC’s findings, and consequently its relevance, will be significantly influenced by how it is communication to the outside world.

Roteiro para acordo global sobre o clima (Correio Braziliense)

JC e-mail 4393, de 28 de Novembro de 2011.

Por Connie Hedegaard

Quando ministros e negociadores de todo o mundo se reunirem, a partir de hoje, em Durban (África do Sul) para a Conferência da ONU sobre o Clima, será um momento decisivo para avançarmos no combate internacional contra as alterações climáticas.

Alguns perguntarão: não poderíamos aguardar um pouco e tratar do problema do clima depois de termos resolvido a crise da dívida na Europa, quando houver uma nova retomada do crescimento? A resposta é não. As inundações na Tailândia e as secas no Texas e no Chifre da África são apenas alguns dos mais recentes alertas de que o problema do clima não perdeu o caráter de urgência, porque as alterações climáticas estão se agravando. O recente relatório World Energy Outlook, da Agência Internacional da Energia (AIE), foi mais um sinal de alarme: o tempo está se esgotando e a fatura vai multiplicar-se assustadoramente se não agirmos já.

Portanto, o que podemos conseguir em Durban? Os comentários da comunicação social nos deixam a impressão de que só há uma forma de aferir o êxito: levar os países desenvolvidos a subscreverem um segundo período de compromisso do Protocolo de Kyoto, após o termo do primeiro, em 2012.

Sejamos claros: a UE apoia o Protocolo de Kyoto. Baseamos a nossa legislação nos seus princípios; somos a região do mundo com o objetivo mais ambicioso no âmbito de Kyoto – e estamos a cumpri-lo. Na verdade, estamos a caminho de ultrapassar o nosso objetivo.

Mas o Protocolo de Kyoto baseia-se numa distinção nítida entre países desenvolvidos e países em desenvolvimento e exige medidas apenas aos primeiros. Não lhes parece que a evolução da economia mundial ao longo das últimas duas décadas tem atenuado cada vez mais essa distinção?

Consideremos Cingapura e Coreia do Sul. São fortes economias de exportação, com indústrias competitivas e classificações impressionantes no Índice de Desenvolvimento Humano publicado pelo Programa das Nações Unidas para o Desenvolvimento. Contudo, no Protocolo de Quioto, figuram como países em desenvolvimento. Ou consideremos uma economia emergente dinâmica como o Brasil. Tem indústrias florescentes, recursos naturais imensos e um rendimento per capita visivelmente superior aos da Bulgária ou da Romênia, por exemplo.

Os padrões de poluição estão igualmente colocando em causa a distinção entre países desenvolvidos e países em desenvolvimento. Segundo a AIE, o atual aumento da poluição pelo CO2 é causado principalmente por economias emergentes dependentes do carvão. E essa tendência só irá acentuar-se. Até 2035, 90% do aumento da procura de energia caberão a países não pertencentes à OCDE. No caso da China, por exemplo, as suas emissões relacionadas com a energia triplicaram desde 1990, o que a torna o maior emissor mundial. Em média, um cidadão chinês emite hoje mais do que, por exemplo, um português, um sueco ou um húngaro. Por conseguinte, o mundo simplesmente não pode combater com eficácia as alterações climáticas sem o envolvimento da China e de outras economias emergentes.

Outro problema é que os Estados Unidos não subscreveram Kyoto – nem jamais subscreverão -, além de que o Japão, a Rússia e o Canadá disseram claramente que não tencionam aderir a um segundo período de compromisso. Significa isso, em suma, que, se a União Europeia subscrevesse um segundo período relativo a Kyoto, juntamente com algumas outras economias desenvolvidas, poderia cobrir, no máximo, 16% das emissões mundiais, quando o primeiro período de Kyoto cobria cerca de um terço. Como se pode chamar a isso uma vitória para o clima? Por outras palavras, esse critério não tem hipótese de manter o aumento da temperatura abaixo de 2°C (3,6°F), que a comunidade internacional reconheceu dever ser o nosso objetivo comum.

Para termos hipótese de alcançar aquele objetivo, o que realmente necessitamos é de um quadro de ação mundial por parte de todas as grandes economias, tanto no mundo desenvolvido quanto no mundo em desenvolvimento. Um quadro de ação que verdadeiramente reflita o mundo do século 21, no qual todos os compromissos tenham o mesmo peso jurídico. A União Europeia está aberta a um segundo período de Kyoto, sob condição de que a integridade ambiental de Kyoto seja melhorada e Durban aprove um roteiro e um calendário claros para a conclusão desse quadro nos anos mais próximos e a sua aplicação, ao mais tardar, em 2020.

É minha esperança que todos os países demonstrem a vontade e a liderança política necessárias para se iniciar um tal processo em Durban. Em Copenhague, os dirigentes juraram manter-se abaixo dos 2°C. Soou a hora de provarem que não falavam em vão.

Conferência sobre aquecimento começa sem clima na África do Sul (Folha de São Paulo)

C e-mail 4393, de 28 de Novembro de 2011.

COP-17, que reúne 190 países até o dia 10, não tem o objetivo de conseguir um novo acordo.

Já virou clichê dizer que as conferências do clima nunca alcançam o objetivo desejado. A COP-17 (17ª Conferência das Partes da Convenção do Clima das Nações Unidas), que começa hoje sob o signo da crise econômica, deve romper esse padrão: nela, o próprio objetivo foi diluído. Os diplomatas de 190 países que se reúnem de hoje ao próximo dia 10 em Durban, na África do Sul, não perseguem mais um acordo global contra emissões de gases-estufa. O que está em jogo é a continuidade ou não do acordo que existe hoje, o pífio Protocolo de Kyoto.

Para a diplomacia brasileira, a reunião terá sido um sucesso se as nações desenvolvidas concordarem em prolongar a vida do protocolo até 2020. E um fracasso em Durban traria um ônus extra para o Brasil, que sediará a próxima conferência ambiental da ONU, a Rio +20.

Kyoto, assinado em 1997, previa que os países industrializados cortassem suas emissões em 5,2% em relação a 1990 até 2012. Como se sabe, os EUA ficaram de fora, e o acordo teve impacto virtualmente nulo sobre a concentração global de gases-estufa na atmosfera, que cresceu 7% de 1997 a 2011.

Não há acordo sobre o tipo de regime que possa ampliar o combate às emissões de carbono depois que ele expirar. “Se deixarmos morrer Kyoto, o consenso é que não se vai mais conseguir um acordo desse tipo”, disse o embaixador André Corrêa do Lago, negociador-chefe do Brasil na área de clima.

Ainda mais inútil – O problema é que também há consenso de que um eventual segundo período de compromisso de Kyoto será ainda mais inútil do que o primeiro para o objetivo-mor da convenção: evitar que o planeta aqueça mais de 2°C. Os EUA, principal emissor histórico, não ratificarão Kyoto nunca. Os países emergentes, hoje os maiores emissores do planeta, não têm metas obrigatórias pelo acordo.

E outros países industrializados com obrigações no acordo, como Japão e Rússia, já anunciaram que não participarão de um segundo período: apenas dizem que vão implementar as metas voluntárias de corte de emissões com que se comprometeram na conferência de Copenhague, em 2009.

Corrêa do Lago admite que esse cenário deixa dentro de Kyoto apenas a União Europeia e outros países menores, que somam somente 15% das emissões mundiais. Sem Kyoto, porém, os países em desenvolvimento temem que se perca a diferenciação que obriga os países ricos (que poluíram mais no passado) a fazer mais.

Os países desenvolvidos, por sua vez, apelam para um acordo único. Na semana passada, o ministro do Ambiente britânico, Chris Huhne, defendeu que um tratado legalmente vinculante que envolvesse também os emergentes fosse fechado em 2015. O Brasil – que se obrigou, por lei, a cortar emissões até 2020 – não fecha a porta a um acordo desses. Mas antes os ricos terão de entregar Kyoto.

Outro impasse deve girar em torno do dinheiro que os países ricos prometeram desembolsar para o combate à mudança climática nos pobres: US$ 30 bilhões entre 2010 e 2012 e um Fundo Verde de US$ 100 bilhões por ano a partir de 2020. Com a crise da dívida dos EUA e o colapso financeiro da Europa, os principais doadores, falar em dinheiro para o clima é a proverbial corda em casa de enforcado.

A crise tem feito os países ricos levantarem dúvidas sobre que tipo de verba constitui o Fundo Verde. O discurso dos ricos agora, dizem diplomatas brasileiros, é que o dinheiro do fundo verde deve ser sobretudo privado. “Não foram setores privados que se comprometeram com o dinheiro, portanto eles não poderão ser cobrados”, afirmou o diplomata brasileiro André Odembreit.

É tarde para conter aquecimento, diz análise – Enquanto os diplomatas tentam tirar as negociações internacionais sobre o clima da irrelevância, cientistas alertam que é provavelmente tarde demais para evitar a mudança climática perigosa.

Um relatório divulgado na semana passada pelo Pnuma (Programa das Nações Unidas para o Meio Ambiente) sugere que o planeta terá em 2020, na melhor das hipóteses, 6 bilhões de toneladas de CO₂ “sobrando” no ar em relação ao que precisaria para cumprir a meta de evitar um aquecimento global maior do que 2°C neste século. Para ter mais de 66% de chance de cumprir a meta, seria preciso limitar as emissões de gases-estufa a 44 bilhões de toneladas de CO₂ em 2020.

Hoje elas são de 50 bilhões de toneladas, e permanecerão nessa faixa somente se todos os países cumprirem estritamente as metas mais ambiciosas com as quais disseram que poderiam se comprometer no Acordo de Copenhague, em 2009 -a UE, por exemplo, disse que cortaria 30% de suas emissões em vez dos 20% que prometeu, mas só se outros países aumentassem sua ambição.

Caso pouco seja feito – o que parece o cenário mais provável considerando o contexto político atual -, as emissões atingirão 55 bilhões de toneladas, e o “buraco” para cumprir a meta será de 9 bilhões em vez de 6 bilhões de toneladas de CO2 em 2020. Mesmo a trajetória mais benigna de emissões põe o planeta no rumo de esquentar de 2,5°C a 5°C até 2100.

O relatório do Pnuma, intitulado “Bridging the Gap” (algo como “Tapando o Buraco”), tenta passar uma mensagem positiva: ele afirma que é “tecnicamente possível e economicamente viável” fechar o buraco de 6 bilhões de toneladas até 2020 cortando emissões em vários setores.

A probabilidade de que isso aconteça, porém, é tão pequena que nem os cientistas que elaboraram o documento acreditam nela. “Até a véspera da divulgação do estudo, nós ainda estávamos divididos sobre se deveríamos passar uma mensagem esperançosa ou pessimista”, disse à Folha Suzana Kahn Ribeiro, professora da Coppe-UFRJ e uma das coordenadoras do trabalho.

Na divulgação, porém, prevaleceu a necessidade política do Pnuma de adotar a estratégia da esperança, para estimular os negociadores em Durban a tentar um resultado mais ambicioso.

Can Climate Science Predict Extreme Weather? (Scientific American)

This year’s rash of severe weather is changing climate science. As policymakers call for better information, scientists are scrambling to understand the link between increasing emissions and natural disaster

By Joshua Zaffos and The Daily Climate  | November 2, 2011

DENVER, Colo. – 2011 may well be remembered as the year of extremeweather in the United States, with drought in Texas, floods along the Mississippi River, a freak October snowstorm on the East Coast. Tornadoes alone would make the year memorable, with some 1,270 twisters causing 544 deaths and $25 billion in damages.

The outbreak is reshaping climate science, as researchers hone their abilities to predict severe weather and link the record-shattering destruction to humanity’s increasing emissions.

The goal: To provide better information to policymakers and local officials who must plan for and adapt to changes. “It’s a rapidly developing field,” said Peter Stott, head of climate monitoring and attribution at the Met Office, Britain’s national weather service.

Stott led one of the first studies attributing a single extreme weather event to climate change: The 2003 European heat wave, which killed 40,000 and was the hottest summer on record since 1540.  The study concluded that human influence more than doubled the event’s likelihood.

Last week, a study published in the journal Proceedings of the National Academy of Sciences concluded there was an 80 percent chance that the killer Russian heat wave of 2010 would not have happened without the added push of global warming.

Now, Stott and other researchers are melding weather forecasting skills with pioneering computer models to attribute – or link – individual weather events to climate change. Understanding how climate change influences the weather is increasingly seen as key to predicting natural disasters, Stott said, and the new studies should help policymakers anticipate the conditions and trends associated with weather extremes. “There’s this very strong connection between attribution and prediction,” noted Stott, who spoke on these issues before colleagues last week at the World Climate Research Programme conference here in Denver.

The efforts are steering the next steps of the Intergovernmental Panel on Climate Change, the international body of scientists that reviews and assesses the vast pool of climate research for policymakers worldwide. The next IPCC assessment is due in 2013 – the fifth from the panel since 1990. For the first time it will include “predictions” – near-term and long-term climate forecasts based on actual conditions – instead of “projections” that simulate hypothetical scenarios and carbon emission rates.

The distinction is an advance for climate science and the IPCC, said Kevin Trenberth, who runs the Climate Analysis Section at the National Center for Atmospheric Research in Boulder, Colo.

Previous IPCC assessments have cited projections that are not grounded in current or historical conditions. Instead, policymakers are given “what-if” scenarios, such as how the future climate might react to different greenhouse-gas emissions over the coming decades. The results show changes between two assumed moments in time, Trenberth said, but they lack a starting point tied to observed data and, ultimately, are informed guesses of future carbon dioxide levels and their consequences.

Climate model predictions, on the other hand, are like weather forecasts. They start from a current or historical moment to analyze climate changes. By grabbing more measurements and using new techniques, advanced climate models reveal more clearly how the atmosphere responds to increased water moisture, warmer sea temperatures and melting sea ice, all impacts of increased carbon. Compared to projections, predictions allow scientists to offer near-term climate forecasts, which should help policymakers prepare for potential adaptations in the next few decades.

The change from projections to predictions is made possible in part by a new generation of more powerful computer models. The last IPCC assessment report, published in 2007, made minor mention of feedbacks – environmental processes and interactions that can intensify extreme climate events, said Sonia Seneviratne, a professor at the Swiss Federal Institute of Technology in Zurich, who specializes on the topic. New data have since opened up scientists’ understanding of their importance.

Seneviratne is the lead author of an IPCC special report to be released later this month that focuses on climate change and extreme events. Research in this area has been “substantial and justifies a separate assessment,” she said, adding that it’s particularly a topic of interest for officials concerned with disaster preparedness and risk reduction.

The special report concludes that scientists are “virtually certain” the world will see more extremes in heat and that some places in the world will become “increasingly marginal as places to live,” according to the Associated Press, which obtained a draft. The draft also concludes there is at least a two-in-three chance that man-made global warming has already worsened weather extremes, according to the AP. The document is subject to change and needs approval from diplomats meeting in Uganda mid-month.

There are some caveats to these new climate predictions, however.

Writing in a scientific journal last year, Trenberth warned colleagues that the promise of more accurate representations of climate change will introduce new scientific uncertainties inherent to modeling more complex and realistic situations. Just as weather forecasting evokes its share of skepticism and doubt, climate predictions will likely represent a new communications challenge – and fodder for controversy and criticism – for climate scientists, said Trenberth.

“It’s about communication,” agreed Stott, who is the lead author of the 2013 IPCC report’s section on attribution and detection of climate change. “An understanding of where extreme weather fits into the longer-term picture of a changing climate helps people put this into context, and [whether] this is something that is going to become more common in the future and therefore we need to give more attention and be more prepared for these things.”

Stott and other scientists at a handful of modeling centers worldwide are focusing on the relation between climate change and extreme weather through a new initiative, Attribution of Climate-related Events. Stott says the project will move scientists further along toward forecasting extreme events and mapping the interactions with climate change.

“The goal is to be able to develop the tools and the skills, so we know when we can be confident and provide trustworthy assessments, and to do this in a timely fashion – in the immediate aftermath of a particular situation,” Stott said. “At the moment, we’re not really geared up for that. It’s very much research mode.> We’ve hardly scratched the surface.”

The human cause of climate change: Where does the burden of proof lie? (Wiley)

Dr. Kevin Trenberth advocates reversing the ‘null hypothesis’

The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role.

In response to Trenberth’s argument a second review, by Dr Judith Curry, focuses on the concept of a ‘null hypothesis’ the default position which is taken when research is carried out. Currently the null hypothesis for climate change attribution research is that humans have no influence.

“Humans are changing our climate. There is no doubt whatsoever,” said Trenberth. “Questions remain as to the extent of our collective contribution, but it is clear that the effects are not small and have emerged from the noise of natural variability. So why does the science community continue to do attribution studies and assume that humans have no influence as a null hypothesis?”

To show precedent for his position Trenberth cites the 2007 report by the Intergovernmental Panel on Climate Change which states that global warming is “unequivocal”, and is “very likely” due to human activities.

Trenberth also focused on climate attribution studies which claim the lack of a human component, and suggested that the assumptions distort results in the direction of finding no human influence, resulting in misleading statements about the causes of climate change that can serve to grossly underestimate the role of humans in climate events.

“Scientists must challenge misconceptions in the difference between weather and climate while attribution studies must include a human component,” concluded Trenberth. “The question should no longer be is there a human component, but what is it?”

In a second paper Dr Judith Curry, from the Georgia Institute of Technology, questions this position, but argues that the discussion on the null hypothesis serves to highlight fuzziness surrounding the many hypotheses related to dangerous climate change.

“Regarding attribution studies, rather than trying to reject either hypothesis regardless of which is the null, there should be a debate over the significance of anthropogenic warming relative to forced and unforced natural climate variability,” said Curry.

Curry also suggested that the desire to reverse the null hypothesis may have the goal of seeking to marginalise the climate sceptic movement, a vocal group who have challenged the scientific orthodoxy on climate change.

“The proponents of reversing the null hypothesis should be careful of what they wish for,” concluded Curry. “One consequence may be that the scientific focus, and therefore funding, would also reverse to attempting to disprove dangerous anthropogenic climate change, which has been a position of many sceptics.”

“I doubt Trenberth’s suggestion will find much support in the scientific community,” said Professor Myles Allen from Oxford University, “but Curry’s counter proposal to abandon hypothesis tests is worse. We still have plenty of interesting hypotheses to test: did human influence on climate increase the risk of this event at all? Did it increase it by more than a factor of two?”

Mixed messages on climate ‘vulnerability’ (BBC)

13 November 2011 Last updated at 14:45 GMT

Cyclist in floodThere are concerns that climate change may exacerbate flooding in cities such as Bangkok

One of the most striking new voices on climate change that’s emerged since the UN summit in Copenhagen two years ago is the Climate Vulnerable Forum.

The grouping includes small island states vulnerable to extreme weather events and sea level rise, those with immense spans of low-lying coastline such as Vietnam and Bangladesh, and dry nations of East Africa.

It’s currently holding a meeting in Bangladesh, with UN Secretary-General Ban Ki-moon as the keynote speaker.

These countries feel vulnerable as a result of several types of projected climate impact.

In increasing order of suddenness, there are what you might call “steady-state” impacts such as rising sea levels; increased separation of weather into more concentrated wet periods and dry periods; and a greater occurrence of extreme weather events such as hurricanes, floods, heatwaves and droughts.

But what can science really tell us about these extremes?

While the vulnerable meet in Dhaka, the Intergovernmental Panel on Climate Change (IPCC) will be sitting down in Kampala to answer the question.

For almost a week, government delegates will pore over the summary of the IPCC’s latest report on extreme weather, with the lead scientific authors there as well. They’re scheduled to emerge on Friday with an agreed document.

The draft, which has found its way into my possession, contains a lot more unknowns than knowns.

On the one hand, it says it is “very likely” that the incidence of cold days and nights has gone down and the incidence of warm days and nights has risen globally.

And the human and financial toll of extreme weather events has risen.

Human hand fingered?

But when you get down to specifics, the academic consensus is far less certain.

Glacier, AlaskaEnhanced glacier melt could speed up sea level rise in the coming decades

There is “low confidence” that tropical cyclones have become more frequent, “limited-to-medium evidence available” to assess whether climatic factors have changed the frequency of floods, and “low confidence” on a global scale even on whether the frequency has risen or fallen.

In terms of attribution of trends to rising greenhouse gas concentrations, the uncertainties continue.

While it is “likely” that anthropogenic influences are behind the changes in cold days and warm days, there is only “medium confidence” that they are behind changes in extreme rainfall events, and “low confidence” in attributing any changes in tropical cyclone activity to greenhouse gas emissions or anything else humanity has done.

(These terms have specific meanings in IPCC-speak, with “very likely” meaning 90-100% and “likely” 66-100%, for example.)

And for the future, the draft gives even less succour to those seeking here a new mandate for urgent action on greenhouse gas emissions, declaring: “Uncertainty in the sign of projected changes in climate extremes over the coming two to three decades is relatively large because climate change signals are expected to be relatively small compared to natural climate variability”.

It’s also explicit in laying out that the rise in impacts we’ve seen from extreme weather events cannot be laid at the door of greenhouse gas emissions: “Increasing exposure of people and economic assets is the major cause of the long-term changes in economic disaster losses (high confidence).

“Long-term trends in normalized economic disaster losses cannot be reliably attributed to natural or anthropogenic climate change.”

The succour only lasts for so long, however.

If the century progresses without restraints on greenhouse gas emissions, their impacts will come to dominate, it forecasts:

  • “It is very likely that the length, frequency and/or intensity of warm spells, including heat waves, will continue to increase over most land areas…
  • “It is likely that the frequency of heavy precipitation or the proportion of total rainfall from heavy falls will increase in the 21st Century over many areas of the globe…
  • “Mean tropical cyclone maximum wind speed is likely to increase…
  • “There is medium confidence that droughts will intensify in the 21st Century in some seasons and areas…
  • “Low-probability high-impact changes associated with the crossing of poorly understood thresholds cannot be excluded, given the transient and complex nature of the climate system.”

The draft report makes clear that lack of evidence or lack of confidence on a particular impact doesn’t mean it won’t occur; just that it’s hard to tell.

Climate a distraction?

It’s impossible to read the draft without coming away with the impression that with or without anthropogenic climate change, extreme weather impacts are going to be felt more and more, simply because there are more and more people on planet Earth – particularly in the swelling “megacities” of the developing world that overwhelmingly lie on the coast or on big rivers close to the coast.

President NasheedPresident Nasheed of the Maldives has warned that climate change may mean the end of his nation

The current Bangkok floods are a case in point.

As UK academic Mike Hulme and others have argued, such events will occur whether exacerbated by climate change or not; and vulnerable societies need protection irrespective of climate change.

He’s argued for a divorce, therefore, between the issues of adaptation, which he says could usefully be added into the overall process of overseas development assistance, and mitigation of emissions.

It’s not proved to be a popular notion with developing world governments, which remain determined to tie the two together in the UN climate process.

Governments of vulnerable countries argue that as developed nations caused the climate change problem, they must compensate those that suffer its impacts with money above and beyond aid.

Developing countries like the fact that under the UN climate process, the rich are committed to funding adaptation for the poor.

Yet as the brief prepared for the Dhaka meeting by the humanitarian charity Dara shows, it isn’t happening anywhere near as fast as it ought to be.

Only 8% of the “fast-start finance” pledged in Copenhagen, it says, has actually found its way to recipients.

It’s possible – no, it’s “very likely” – that the IPCC draft will be amended as the week progresses, and presumably the governments represented at the Climate Vulnerable Forum will be asking their delegates to inject a greater sense of urgency.

Although there are sobering messages, they’re not for everyone.

The warning that “some local areas will become increasingly marginal as places to live or in which to maintain livelihoods” under increased climate impacts, and that “for locations such as atolls, in some cases it is possible that many residents will have to relocate” are, in their understated way, quite chilling.

But very few of the world’s seven billion live on atolls; so will this be enough to provide a wake-up call to other countries?

It’s also possible to argue that extreme weather isn’t really the issue for the small island developing states, or for those with long flat coastlines.

The big issue (which the IPCC is much more confident about) is sea level rise – slow, progressive, predictable; capable of being dealt with in some cases (think the Netherlands) provided the will and money are there.

But capable of wiping a country off the map if those two factors are absent.

This is one of the reasons why the Climate Vulnerable Forum established itself.

They felt that although both developed and developing nations understood vulnerability in theory, they didn’t get the message viscerally.

Whether they will by the end of the week when the IPCC releases the final version, I’m not so sure.

Anthropologists Consider a New Code of Ethics (The Chronicle of Higher Education)

November 20, 2011

By Dan Berrett

Today’s anthropologists are apt to work far away from the unspoiled villages that brought fame to the discipline’s early practitioners.

Instead, they might be in a hospital room observing patients, at a construction site gauging its archaeological significance, or in a corporate office examining organizational behavior, among other scenarios.

Those diverse contexts may explain why it has proved to be no easy job for anthropologists to create a new set of ethical guidelines. After three years spent seeking opinion and working on new guidelines, the American Anthropological Association is moving toward changes that some in the discipline fear will water down anthropologists’ obligations to the people they study.

“Dealing with ethics codes is complicated,” said David H. Price, a member of the committee charged with revising the guidelines. The word was echoed last week by fellow committee members at a panel on ethics at the association’s annual meeting here. Basic ethical principles might seem clear at the outset, but then point to different courses of action depending on the context, said Mr. Price, a professor at Saint Martin’s University, in Washington. “You can start with something simple, like ‘Do no harm,'” he said, and then find yourself hamstrung if those guidelines are written too specifically ­— or lost at sea if they are too vague.

One of the most notable changes in the proposed new code was to remove what many anthropologists call the “prime directive.”

The previous code, which dates to 1998 (though incremental changes have been made since then), told anthropologists that they “have primary ethical obligations to the people, species, and materials they study and to the people with whom they work.”

By many accounts, that directive has meant that an anthropologist’s obligation to his or her research subject can eclipse the goal of acquiring new knowledge. In other words, if research goes against the interests of subjects, then that research ought to be stopped.

The newer version, which the association’s executive board accepted for review at this year’s meeting but did not formally adopt, is more nuanced. It explains that the primary ethical obligation is “to avoid doing harm to the lives, communities, or environments” that anthropologists study.

The shift struck some as important. At other sessions during the annual meeting, several speakers and audience members said they held themselves to a different standard. It was not enough to keep from hurting their subjects. They should advocate for them.

The new code may do little to change that sense of obligation. It persists, in part, because of the assumption that an anthropologist is still that lone researcher closely observing a vulnerable tribe in a remote area, some on the committee said.

“That pure anthropology maybe never existed,” said Dena K. Plemmons, chair of the committee and a research ethicist at the University of California at San Diego. “Our subjects are tremendously diverse and we have diverse responsibilities.”

For example, Simon J. Craddock Lee, an assistant professor of medical anthropology at the University of Texas Southwestern Medical Center at Dallas, said his subjects are “well-paid cancer surgeons who give care to disenfranchised people.”

He has obligations to both groups, he said. “If my subjects are doctors, how do I balance my obligations to the people who are truly vulnerable?”

One audience member suggested that his chief loyalty should be to the person or group who is most at risk of harm among those being studied.

While that might seem straightforward, Mr. Lee replied, everyone—including the poor and vulnerable—has an agenda.

“We can’t assume there’s a David-and-Goliath relationship,” he said. “It’s not clean enough to say you can sort the good sheep from the goats.”

Ethics, or Politics?

The question of clandestine research offered another case in which a seemingly simple principle can become complicated when applied to field work. To some, discouraging clandestine research meant that an anthropologist should never deceive subjects and should always share his or her work publicly.

But Laura A. McNamara, an anthropologist who works for the U.S. Department of Energy’s Sandia National Laboratories, disagreed, saying that some anthropologists study classified information; they cannot make their findings public.

Even deceit can have its place, she added. Nancy Scheper-Hughes, a professor of medical anthropology at the University of California at Berkeley, for example, did research that exposed the organ-trafficking trade. Her work never would have been made public if she had believed that her primary obligation was to her subjects, who were, after all, organ traffickers.

The real problem, Ms. McNamara and her fellow committee members agreed, is not when research is clandestine, but when it is “compartmentalized,” which means a researcher may not know who is using or financing the research, or what the implications will be.

“There is no way you can communicate an informed perspective,” she said.

How anthropologists wield ethical guidelines also came up for scrutiny. Anthropologists push most fervently to revise their ethics when they disagree with the politics underlying controversial research, several speakers noted.

“We go to high Sturm und Drang” about ethics, Ms. McNamara said, when political objections arise about who is doing anthropological research for whom—especially when it’s for the government, corporations, or the rich and powerful. “Ethics becomes conflated with politics in ways that I find profoundly distressing,” she said.

Some anthropologists pushed to revise the ethics code in 2007, said Ms. Plemmons, when acontroversy erupted over the Human Terrain System, a program that embedded anthropologists with United States military units. The association’s executive board disapproved of anthropologists’ involvement in the act of making war, calling it “an unacceptable application of anthropological expertise” which should, instead, serve “the humane causes of global peace and social justice.”

Education and Punishment

Committee members said they also heard from anthropologists who wanted an ethics code that could be enforced. That way, anthropologists who act badly could be punished or cast out of the discipline.

The association once held the power to adjudicate claims of ethical breaches, Mr. Price said. But when he reviewed records of the association’s work from that period, he saw that most claims involved what he called “sleaziness,” or cases in which professors harassed students or took credit for their research. While unethical, those breaches were not specific to anthropology and needed no separate code beyond those that already exist, he said.

Assuming responsibility for adjudicating ethical disputes presented another set of problems, said several speakers. It would mean a new mission and structure for the association, which would have to hire investigators to police wrongdoing and claim the power to credential who gets to call him- or herself an anthropologist. Many times, such complaints can be handled through an institutional review board or a university.

The association has seen first-hand how difficult such investigations can be. In 2001 and 2002, it probed claims of wrongdoing and ethical malpractice against anthropologists and geneticists in the Amazon in the 1960s. The association later published a report finding fault with some of the scholars’ conduct in what became known as the Darkness in El Dorado controversy (after a journalist’s account by that name), only to rescind its own report in 2005.

Besides, the ethics committee surveyed members and learned that most anthropologists are not all that interested in using ethical guidelines as a means to punish each other. What most anthropologists wanted, they said, was some form of general guidance, an educational tool to train future anthropologists.

World headed for irreversible climate change in five years, IEA warns (The Guardian)

If fossil fuel infrastructure is not rapidly changed, the world will ‘lose for ever’ the chance to avoid dangerous climate change

The world is likely to build so many fossil-fuelled power stations, energy-guzzling factories and inefficient buildings in the next five years that it will become impossible to hold global warming to safe levels, and the last chance of combating dangerous climate change will be “lost for ever”, according to the most thorough analysis yet of world energy infrastructure.

Anything built from now on that produces carbon will do so for decades, and this “lock-in” effect will be the single factor most likely to produce irreversible climate change, the world’s foremost authority on energy economics has found. If this is not rapidly changed within the next five years, the results are likely to be disastrous.

“The door is closing,” Fatih Birol, chief economist at the International Energy Agency, said. “I am very worried – if we don’t change direction now on how we use energy, we will end up beyond what scientists tell us is the minimum [for safety]. The door will be closed forever.”

If the world is to stay below 2C of warming, which scientists regard as the limit of safety, then emissions must be held to no more than 450 parts per million (ppm) of carbon dioxide in the atmosphere; the level is currently around 390ppm. But the world’s existing infrastructure is already producing 80% of that “carbon budget”, according to the IEA’s analysis, published on Wednesday. This gives an ever-narrowing gap in which to reform the global economy on to a low-carbon footing.

If current trends continue, and we go on building high-carbon energy generation, then by 2015 at least 90% of the available “carbon budget” will be swallowed up by our energy and industrial infrastructure. By 2017, there will be no room for manoeuvre at all – the whole of the carbon budget will be spoken for, according to the IEA’s calculations.

Birol’s warning comes at a crucial moment in international negotiations on climate change, as governments gear up for the next fortnight of talks in Durban, South Africa, from late November. “If we do not have an international agreement, whose effect is put in place by 2017, then the door to [holding temperatures to 2C of warming] will be closed forever,” said Birol.

But world governments are preparing to postpone a speedy conclusion to the negotiations again. Originally, the aim was to agree a successor to the 1997 Kyoto protocol, the only binding international agreement on emissions, after its current provisions expire in 2012. But after years of setbacks, an increasing number of countries – including the UK, Japan and Russia – now favour postponing the talks for several years.

Both Russia and Japan have spoken in recent weeks of aiming for an agreement in 2018 or 2020, and the UK has supported this move. Greg Barker, the UK’s climate change minister, told a meeting: “We need China, the US especially, the rest of the Basic countries [Brazil, South Africa, India and China] to agree. If we can get this by 2015 we could have an agreement ready to click in by 2020.” Birol said this would clearly be too late. “I think it’s very important to have a sense of urgency – our analysis shows [what happens] if you do not change investment patterns, which can only happen as a result of an international agreement.”

Nor is this a problem of the developing world, as some commentators have sought to frame it. In the UK, Europe and the US, there are multiple plans for new fossil-fuelled power stations that would contribute significantly to global emissions over the coming decades.

The Guardian revealed in May an IEA analysis that found emissions had risen by a record amount in 2010, despite the worst recession for 80 years. Last year, a record 30.6 gigatonnes (Gt) of carbon dioxide poured into the atmosphere from burning fossil fuels, a rise of 1.6Gt on the previous year. At the time, Birol told the Guardian that constraining global warming to moderate levels would be “only a nice utopia” unless drastic action was taken.

The new research adds to that finding, by showing in detail how current choices on building new energy and industrial infrastructure are likely to commit the world to much higher emissions for the next few decades, blowing apart hopes of containing the problem to manageable levels. The IEA’s data is regarded as the gold standard in emissions and energy, and is widely regarded as one of the most conservative in outlook – making the warning all the more stark. The central problem is that most industrial infrastructure currently in existence – the fossil-fuelled power stations, the emissions-spewing factories, the inefficient transport and buildings – is already contributing to the high level of emissions, and will do so for decades. Carbon dioxide, once released,stays in the atmosphere and continues to have a warming effect for about a century, and industrial infrastructure is built to have a useful life of several decades.

Yet, despite intensifying warnings from scientists over the past two decades, the new infrastructure even now being built is constructed along the same lines as the old, which means that there is a “lock-in” effect – high-carbon infrastructure built today or in the next five years will contribute as much to the stock of emissions in the atmosphere as previous generations.

The “lock-in” effect is the single most important factor increasing the danger of runaway climate change, according to the IEA in its annual World Energy Outlook, published on Wednesday.

Climate scientists estimate that global warming of 2C above pre-industrial levels marks the limit of safety, beyond which climate change becomes catastrophic and irreversible. Though such estimates are necessarily imprecise, warming of as little as 1.5C could cause dangerous rises in sea levels and a higher risk of extreme weather – the limit of 2C is now inscribed in international accords, including the partial agreement signed at Copenhagen in 2009, by which the biggest developed and developing countries for the first time agreed to curb their greenhouse gas output.

Another factor likely to increase emissions is the decision by some governments to abandon nuclear energy, following the Fukushima disaster. “The shift away from nuclear worsens the situation,” said Birol. If countries turn away from nuclear energy, the result could be an increase in emissions equivalent to the current emissions of Germany and France combined. Much more investment in renewable energy will be required to make up the gap, but how that would come about is unclear at present.

Birol also warned that China – the world’s biggest emitter – would have to take on a much greater role in combating climate change. For years, Chinese officials have argued that the country’s emissions per capita were much lower than those of developed countries, it was not required to take such stringent action on emissions. But the IEA’s analysis found that within about four years, China’s per capita emissions were likely to exceed those of the EU.

In addition, by 2035 at the latest, China’s cumulative emissions since 1900 are likely to exceed those of the EU, which will further weaken Beijing’s argument that developed countries should take on more of the burden of emissions reduction as they carry more of the responsibility for past emissions.

In a recent interview with the Guardian recently, China’s top climate change official, Xie Zhenhua, called on developing countries to take a greater part in the talks, while insisting that developed countries must sign up to a continuation of the Kyoto protocol – something only the European Union is willing to do. His words were greeted cautiously by other participants in the talks.

Continuing its gloomy outlook, the IEA report said: “There are few signs that the urgently needed change in direction in global energy trends is under way. Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO2 emissions to a new high. Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400bn (£250.7bn).”

Meanwhile, an “unacceptably high” number of people – about 1.3bn – still lack access to electricity. If people are to be lifted out of poverty, this must be solved – but providing people with renewable forms of energy generation is still expensive.

Charlie Kronick of Greenpeace said: “The decisions being made by politicians today risk passing a monumental carbon debt to the next generation, one for which they will pay a very heavy price. What’s seriously lacking is a global plan and the political leverage to enact it. Governments have a chance to begin to turn this around when they meet in Durban later this month for the next round of global climate talks.”

One close observer of the climate talks said the $400bn subsidies devoted to fossil fuels, uncovered by the IEA, were “staggering”, and the way in which these subsidies distort the market presented a massive problem in encouraging the move to renewables. He added that Birol’s comments, though urgent and timely, were unlikely to galvanise China and the US – the world’s two biggest emittters – into action on the international stage.

“The US can’t move (owing to Republican opposition) and there’s no upside for China domestically in doing so. At least China is moving up the learning curve with its deployment of renewables, but it’s doing so in parallel to the hugely damaging coal-fired assets that it is unlikely to ever want (to turn off in order to) to meet climate targets in years to come.”

Energy demand

Energy demand Source: IEAChristiana Figueres, the UN climate chief, said the findings underlined the urgency of the climate problem, but stressed the progress made in recent years. “This is not the scenario we wanted,” she said. “But making an agreement is not easy. What we are looking at is not an international environment agreement — what we are looking at is nothing other than the biggest industrial and energy revolution that has ever been seen.”

Where Did Global Warming Go? (N.Y. Times)

By ELISABETH ROSENTHAL
Published: October 15, 2011

Mark Pernice and Scott Altmann

IN 2008, both the Democratic and Republican candidates for president, Barack Obama and John McCain, warned about man-made global warming and supported legislation to curb emissions. After he was elected, President Obama promised “a new chapter in America’s leadership on climate change,” and arrived cavalry-like at the 2009 United Nations Climate Conference in Copenhagen to broker a global pact.

But two years later, now that nearly every other nation accepts climate change as a pressing problem, America has turned agnostic on the issue.

In the crowded Republican presidential field, most seem to agree with Gov. Rick Perry of Texas that “the science is not settled” on man-made global warming, as he said in a debate last month. Alone among Republicans onstage that night, Jon M. Huntsman Jr. said that he trusted scientists’ view that the problem was real. At the moment, he has the backing of about 2 percent of likely Republican voters.

Though the evidence of climate change has, if anything, solidified, Mr. Obama now talks about “green jobs” mostly as a strategy for improving the economy, not the planet. He did not mention climate in his last State of the Union address. Meanwhile, the administration is fighting to exempt United States airlines from Europe’s new plan to charge them for CO2 emissions when they land on the continent. It also seems poised to approve a nearly 2,000-mile-long pipeline, from Canada down through the United States, that will carry a kind of oil. Extracting it will put relatively high levels of emissions into the atmosphere.

“In Washington, ‘climate change’ has become a lightning rod, it’s a four-letter word,” said Andrew J. Hoffman, director of the University of Michigan’s Erb Institute for Sustainable Development.

Across the nation, too, belief in man-made global warming, and passion about doing something to arrest climate change, is not what it was five years or so ago, when Al Gore’s movie had buzz and Elizabeth Kolbert’s book about climate change, “Field Notes From a Catastrophe,” was a best seller. The number of Americans who believe the earth is warming dropped to 59 percent last year from 79 percent in 2006, according to polling by the Pew Research Group. When the British polling firm Ipsos Mori asked Americans this past summer to list their three most pressing environmental worries, “global warming/climate change” garnered only 27 percent, behind even “overpopulation.”

This fading of global warming from the political agenda is a mostly American phenomenon. True, public enthusiasm for legislation to tackle climate change has flagged somewhat throughout the developed world since the recession of 2008. Nonetheless, in many other countries, legislation to control emissions has rolled out apace. Just last Wednesday, Australia’s House of Representatives passed a carbon tax, which is expected to easily clear the country’s Senate. Europe’s six-year-old carbon emissions trading system continues its yearly expansion. In 2010, India passed a carbon tax on coal. Even China’s newest five-year plan contains a limited pilot cap-and-trade system, under which polluters pay for excess pollution.

The United States is the “one significant outlier” on responding to climate change, according to a recent global research report produced by HSBC, the London-based bank. John Ashton, Britain’s special representative for climate change, said in an interview that “in the U.K., in Europe, in most places I travel to” — but not in the United States — “the starting point for conversation is that this is real, there are clear and present dangers, so let’s get a move on and respond.” After watching the Republican candidates express skepticism about global warming in early September, former President Bill Clinton put it more bluntly, “I mean, it makes us — we look like a joke, right?”

Americans — who produce twice the emissions per capita that Europeans do — are in many ways wired to be holdouts. We prefer bigger cars and bigger homes. We value personal freedom, are suspicious of scientists, and tend to distrust the kind of sweeping government intervention required to confront rising greenhouse gas emissions.

“Climate change presents numerous ideological challenges to our culture and our beliefs,” Professor Hoffman of the Erb Institute says. “People say, ‘Wait a second, this is really going to affect how we live!’ ”

There are, of course, other factors that hardened resistance: America’s powerful fossil-fuel industry, whose profits are bound to be affected by any greater control of carbon emissions; a cold American winter in 2010 that made global warming seem less imminent; and a deep recession that made taxes on energy harder to talk about, and job creation a more pressing issue than the environment — as can be seen in the debate over the pipeline from Canada.

But it is also true that Europe has endured a deep recession and has had mild winters. What’s more, some of the loudest climate deniers are English. Yet the European Union is largely on target to meet its goal of reducing emissions by at least 20 percent over 1990 levels by 2020.

Connie Hedegaard, the European Union’s commissioner on climate action, told me recently: “Look, it was not a piece of cake here either.”

In fact, many countries in Europe have come to see combating climate change and the move to a “greener” economy as about “opportunities rather than costs,” Mr. Ashton said. In Britain, the low-carbon manufacturing sector has been one of the few to grow through the economic slump.

“One thing I’ve been pleasantly surprised about in the E.U. is that despite the economic and financial crisis, the momentum on climate change has more or less continued,” Mr. Ashton said.

And Conservatives, rather than posing an obstacle, are directing aggressive climate policies in much of the world. Before becoming the European Union’s commissioner for climate action, Ms. Hedegaard was a well-known Conservative politician in her native Denmark. In Britain, where a 2008 law required deep cuts in emissions, a coalition Conservative government is now championing a Green Deal.

In the United States, the right wing of the Republican Party has managed to turn skepticism about man-made global warming into a requirement for electability, forming an unlikely triad with antiabortion and gun-rights beliefs. In findings from a Pew poll this spring, 75 percent of staunch conservatives, 63 percent of libertarians and 55 percent of Main Street Republicans said there was no solid evidence of global warming.

“This has become a partisan political issue here in a way it has not elsewhere,” said Andrew Kohut, president of the Pew Research Center. “We are seeing doubts in the U.S. largely because the issue has become a partisan one, with Democrats” — 75 percent of whom say they believe there is strong evidence of climate change — “seeing one thing and Republicans another.”

Europeans understand the challenges in the United States, though they sound increasingly impatient. “We are very much aware of the political situation in the United States and we don’t say ‘do this,’ when we know it can’t get through Congress,” said Ms. Hedegaard, when she was in New York for the United Nations General Assembly last month. But she added:

“O.K. if you can’t commit today, when can you? When are you willing to join in? Australia is making a cap-and-trade system. South Korea is introducing one. New Zealand and the E.U. have it already. So when is the time? That’s the question for the U.S.”

MEANWHILE, in the developing world, emerging economies like India and China are now pursuing aggressive climate policies. “Two years ago the assumption was that the developed world would have to lead, but now China, India and Brazil have jumped in with enthusiasm, and are moving ahead,” said Nick Robins of HSBC Global Research.

Buffeted by two years of treacherous weather that they are less able to handle than richer nations — from floods in India to water shortages in China — developing countries are feeling vulnerable. Scientists agree that extreme weather events will be more severe and frequent on a warming planet, and insurance companies have already documented an increase.

So perhaps it is no surprise that regard for climate change as “a very serious problem” has risen significantly in many developing nations over the past two years. A 2010 Pew survey showed that more than 70 percent of people in China, India and South Korea were willing to pay more for energy in order to address climate change. The number in the United States was 38 percent. China’s 12th five-year plan, for 2011-2015, directs intensive investment to low carbon industries. In contrast, in the United States, there is “no prospect of moving ahead” at a national legislative level, Mr. Robins said, although some state governments are addressing the issue.

In private, scientific advisers to Mr. Obama say he and his administration remain committed to confronting climate change and global warming. But Robert E. O’Connor, program director for decision, risk and management sciences at the National Science Foundation in Washington, said a bolder leader would emphasize real risks that, apparently, now feel distant to many Americans. “If it’s such an important issue, why isn’t he talking about it?”

Desafios do “tsunami de dados” (FAPESP)

Lançado pelo Instituto Microsoft Research-FAPESP de Pesquisas em TI, o livro O Quarto Paradigma debate os desafios da eScience, nova área dedicada a lidar com o imenso volume de informações que caracteriza a ciência atual

07/11/2011

Por Fábio de Castro

Agência FAPESP – Se há alguns anos a falta de dados limitava os avanços da ciência, hoje o problema se inverteu. O desenvolvimento de novas tecnologias de captação de dados, nas mais variadas áreas e escalas, tem gerado um volume tão imenso de informações que o excesso se tornou um gargalo para o avanço científico.

Nesse contexto, cientistas da computação têm se unido a especialistas de diferentes áreas para desenvolver novos conceitos e teorias capazes de lidar com a enxurrada de dados da ciência contemporânea. O resultado é chamado de eScience.

Esse é o tema debatido no livro O Quarto Paradigma – Descobertas científicas na era da eScience, lançado no dia 3 de novembro pelo Instituto Microsoft Research-FAPESP de Pesquisas em TI.

Organizado por Tony Hey, Stewart Tansley, Kristin Tolle – todos da Microsoft Research –, a publicação foi lançada na sede da FAPESP, em evento que contou com a presença do diretor científico da Fundação, Carlos Henrique de Brito Cruz.

Durante o lançamento, Roberto Marcondes Cesar Jr., do Instituto de Matemática e Estatística (IME) da Universidade de São Paulo (USP), apresentou a palestra “eScience no Brasil”. “O Quarto Paradigma: computação intensiva de dados avançando a descoberta científica” foi o tema da palestra de Daniel Fay, diretor de Terra, Energia e Meio Ambiente da MSR.

Brito Cruz destacou o interesse da FAPESP em estimular o desenvolvimento da eScience no Brasil. “A FAPESP está muito conectada a essa ideia, porque muitos dos nossos projetos e programas apresentam essa necessidade de mais capacidade de gerenciar grandes conjuntos de dados. O nosso grande desafio está na ciência por trás dessa capacidade de lidar com grandes volumes de dados”, disse.

Iniciativas como o Programa FAPESP de Pesquisa sobre Mudanças Climáticas Globais (PFPMCG), o BIOTA-FAPESP e o Programa FAPESP de Pesquisa em Bioenergia (BIOEN) são exemplos de programas que têm grande necessidade de integrar e processar imensos volumes de dados.

“Sabemos que a ciência avança quando novos instrumentos são disponibilizados. Por outro lado, os cientistas normalmente não percebem o computador como um novo grande instrumento que revoluciona a ciência. A FAPESP está interessada em ações para que a comunidade científica tome consciência de que há grandes desafios na área de eScience”, disse Brito Cruz.

O livro é uma coleção de 26 ensaios técnicos divididos em quatro seções: “Terra e meio ambiente”, “Saúde e bem-estar”, “Infraestrutura científica” e “Comunicação acadêmica”.

“O livro fala da emergência de um novo paradigma para as descobertas científicas. Há milhares de anos, o paradigma vigente era o da ciência experimental, fundamentada na descrição de fenômenos naturais. Há algumas centenas de anos, surgiu o paradigma da ciência teórica, simbolizado pelas leis de Newton. Há algumas décadas, surgiu a ciência computacional, simulando fenômenos complexos. Agora, chegamos ao quarto paradigma, que é o da ciência orientada por dados”, disse Fay.

Com o advento do novo paradigma, segundo ele, houve uma mudança completa na natureza da descoberta científica. Entraram em cena modelos complexos, com amplas escalas espaciais e temporais, que exigem cada vez mais interações multidisciplinares.

“Os dados, em quantidade incrível, são provenientes de diferentes fontes e precisam também de abordagem multidisciplinar e, muitas vezes, de tratamento em tempo real. As comunidades científicas também estão mais distribuídas. Tudo isso transformou a maneira como se fazem descobertas”, disse Fay.

A ecologia, uma das áreas altamente afetadas pelos grandes volumes de dados, é um exemplo de como o avanço da ciência, cada vez mais, dependerá da colaboração entre pesquisadores acadêmicos e especialistas em computação.

“Vivemos em uma tempestade de sensoriamento remoto, sensores terrestres baratos e acesso a dados na internet. Mas extrair as variáveis que a ciência requer dessa massa de dados heterogêneos continua sendo um problema. É preciso ter conhecimento especializado sobre algoritmos, formatos de arquivos e limpeza de dados, por exemplo, que nem sempre é acessível para o pessoal da área de ecologia”, explicou.

O mesmo ocorre em áreas como medicina e biologia – que se beneficiam de novas tecnologias, por exemplo, em registros de atividade cerebral, ou de sequenciamento de DNA – ou a astronomia e física, à medida que os modernos telescópios capturam terabytes de informação diariamente e o Grande Colisor de Hádrons (LHC) gera petabytes de dados a cada ano.

Instituto Virtual

Segundo Cesar Jr., a comunidade envolvida com eScience no Brasil está crescendo. O país tem 2.167 cursos de sistemas de informação ou engenharia e ciências da computação. Em 2009, houve 45 mil formados nessas áreas e a pós-graduação, entre 2007 e 2009, tinha 32 cursos, mil orientadores, 2.705 mestrandos e 410 doutorandos.

“A ciência mudou do paradigma da aquisição de dados para o da análise de dados. Temos diferentes tecnologias que produzem terabytes em diversos campos do conhecimento e, hoje, podemos dizer que essas áreas têm foco na análise de um dilúvio de dados”, disse o membro da Coordenação da Área de Ciência e Engenharia da Computação da FAPESP.

Em 2006, a Sociedade Brasileira de Computação (SBC) organizou um encontro a fim de identificar os problemas-chave e os principais desafios para a área. Isso levou a diferentes propostas para que o Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) criasse um programa específico para esse tipo de problema.

“Em 2009, realizamos uma série de workshops na FAPESP, reunindo, para discutir essa questão, cientistas de áreas como agricultura, mudanças climáticas, medicina, transcriptômica, games, governo eletrônico e redes sociais. A iniciativa resultou em excelentes colaborações entre grupos de cientistas com problemas semelhantes e originou diversas iniciativas”, disse César Jr.

As chamadas do Instituto Microsoft Research-FAPESP de Pesquisas em TI, segundo ele, têm sido parte importante do conjunto de iniciativas para promover a eScience, assim como a organização da Escola São Paulo de Ciência Avançada em Processamento e Visualização de Imagens Computacionais. Além disso, a FAPESP tem apoiado diversos projetos de pesquisa ligados ao tema.

“A comunidade de eScience em São Paulo tem trabalhado com profissionais de diversas áreas e publicado em revistas de várias delas. Isso é indicação de qualidade adquirida pela comunidade para encarar o grande desafio que teremos nos próximos anos”, disse César Jr., que assina o prefácio da edição brasileira do livro.

Scientists Find Evidence of Ancient Megadrought in Southwestern U.S. (Science Daily)

ScienceDaily (Nov. 6, 2011) — A new study at the the University of Arizona’s Laboratory of Tree-Ring Research has revealed a previously unknown multi-decade drought period in the second century A.D. The findings give evidence that extended periods of aridity have occurred at intervals throughout our past.

Almost 900 years ago, in the mid-12th century, the southwestern U.S. was in the middle of a multi-decade megadrought. It was the most recent extended period of severe drought known for this region. But it was not the first.

The second century A.D. saw an extended dry period of more than 100 years characterized by a multi-decade drought lasting nearly 50 years, says a new study from scientists at the University of Arizona.

UA geoscientists Cody Routson, Connie Woodhouse and Jonathan Overpeck conducted a study of the southern San Juan Mountains in south-central Colorado. The region serves as a primary drainage site for the Rio Grande and San Juan rivers.

“These mountains are very important for both the San Juan River and the Rio Grande River,” said Routson, a doctoral candidate in the environmental studies laboratory of the UA’s department of geosciences and the primary author of the study, which is upcoming in Geophysical Research Letters.

The San Juan River is a tributary for the Colorado River, meaning any climate changes that affect the San Juan drainage also likely would affect the Colorado River and its watershed. Said Routson: “We wanted to develop as long a record as possible for that region.”

Dendrochronology is a precise science of using annual growth rings of trees to understand climate in the past. Because trees add a normally clearly defined growth ring around their trunk each year, counting the rings backwards from a tree’s bark allows scientists to determine not only the age of the tree, but which years were good for growth and which years were more difficult.

“If it’s a wet year, they grow a wide ring, and if it’s a dry year, they grow a narrow ring,” said Routson. “If you average that pattern across trees in a region you can develop a chronology that shows what years were drier or wetter for that particular region.”

Darker wood, referred to as latewood because it develops in the latter part of the year at the end of the growing season, forms a usually distinct boundary between one ring and the next. The latewood is darker because growth at the end of the growing season has slowed and the cells are more compact.

To develop their chronology, the researchers looked for indications of climate in the past in the growth rings of the oldest trees in the southern San Juan region. “We drove around and looked for old trees,” said Routson.

Literally nothing is older than a bristlecone pine tree: The oldest and longest-living species on the planet, these pine trees normally are found clinging to bare rocky landscapes of alpine or near-alpine mountain slopes. The trees, the oldest of which are more than 4,000 years old, are capable of withstanding extreme drought conditions.

“We did a lot of hiking and found a couple of sites of bristlecone pines, and one in particular that we honed in on,” said Routson.

To sample the trees without damaging them, the dendrochronologists used a tool like a metal screw that bores a tiny hole in the trunk of the tree and allows them to extract a sample, called a core. “We take a piece of wood about the size and shape of a pencil from the tree,” explained Routson.

“We also sampled dead wood that was lying about the land. We took our samples back to the lab where we used a visual, graphic technique to match where the annual growth patterns of the living trees overlap with the patterns in the dead wood. Once we have the pattern matched we measure the rings and average these values to generate a site chronology.”

“In our chronology for the south San Juan mountains we created a record that extends back 2,200 years,” said Routson. “It was pretty profound that we were able to get back that far.”

The chronology extends many years earlier than the medieval period, during which two major drought events in that region already were known from previous chronologies.

“The medieval period extends roughly from 800 to 1300 A.D.,” said Routson. “During that period there was a lot of evidence from previous studies for increased aridity, in particular two major droughts: one in the middle of the 12th century, and one at the end of the 13th century.”

“Very few records are long enough to assess the global conditions associated with these two periods of Southwestern aridity,” said Routson. “And the available records have uncertainties.”

But the chronology from the San Juan bristlecone pines showed something completely new:

“There was another period of increased aridity even earlier,” said Routson. “This new record shows that in addition to known droughts from the medieval period, there is also evidence for an earlier megadrought during the second century A.D.”

“What we can see from our record is that it was a period of basically 50 consecutive years of below-average growth,” said Routson. “And that’s within a much broader period that extends from around 124 A.D. to 210 A.D. — about a 100-year-long period of dry conditions.”

“We’re showing that there are multiple extreme drought events that happened during our past in this region,” said Routson. “These megadroughts lasted for decades, which is much longer than our current drought. And the climatic events behind these previous dry periods are really similar to what we’re experiencing today.”

The prolonged drought in the 12th century and the newly discovered event in the second century A.D. may both have been influenced by warmer-than-average Northern Hemisphere temperatures, Routson said: “The limited records indicate there may have been similar La Nina-like background conditions in the tropical Pacific Ocean, which are known to influence modern drought, during the two periods.”

Although natural climate variation has led to extended dry periods in the southwestern U.S. in the past, there is reason to believe that human-driven climate change will increase the frequency of extreme droughts in the future, said Routson. In other words, we should expect similar multi-decade droughts in a future predicted to be even warmer than the past.

Routson’s research is funded by fellowships from the National Science Foundation, the Science Foundation Arizona and the Climate Assessment of the Southwest. His advisors, Woodhouse of the School of Geography and Development and Overpeck of the department of geosciences and co-director of the UA’s Institute of the Environment, are co-authors of the study.

The Human Cause of Climate Change: Where Does the Burden of Proof Lie? (Science Daily)

ScienceDaily (Nov. 3, 2011) — The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role.

In response to Trenberth’s argument a second review, by Dr Judith Curry, focuses on the concept of a ‘null hypothesis’ the default position which is taken when research is carried out. Currently the null hypothesis for climate change attribution research is that humans have no influence.

“Humans are changing our climate. There is no doubt whatsoever,” said Trenberth. “Questions remain as to the extent of our collective contribution, but it is clear that the effects are not small and have emerged from the noise of natural variability. So why does the science community continue to do attribution studies and assume that humans have no influence as a null hypothesis?”

To show precedent for his position Trenberth cites the 2007 report by the Intergovernmental Panel on Climate Change which states that global warming is “unequivocal,” and is “very likely” due to human activities.

Trenberth also focused on climate attribution studies which claim the lack of a human component, and suggested that the assumptions distort results in the direction of finding no human influence, resulting in misleading statements about the causes of climate change that can serve to grossly underestimate the role of humans in climate events.

“Scientists must challenge misconceptions in the difference between weather and climate while attribution studies must include a human component,” concluded Trenberth. “The question should no longer be is there a human component, but what is it?”

In a second paper Dr Judith Curry, from the Georgia Institute of Technology, questions this position, but argues that the discussion on the null hypothesis serves to highlight fuzziness surrounding the many hypotheses related to dangerous climate change.

“Regarding attribution studies, rather than trying to reject either hypothesis regardless of which is the null, there should be a debate over the significance of anthropogenic warming relative to forced and unforced natural climate variability,” said Curry.

Curry also suggested that the desire to reverse the null hypothesis may have the goal of seeking to marginalise the climate sceptic movement, a vocal group who have challenged the scientific orthodoxy on climate change.

“The proponents of reversing the null hypothesis should be careful of what they wish for,” concluded Curry. “One consequence may be that the scientific focus, and therefore funding, would also reverse to attempting to disprove dangerous anthropogenic climate change, which has been a position of many sceptics.”

“I doubt Trenberth’s suggestion will find much support in the scientific community,” said Professor Myles Allen from Oxford University, “but Curry’s counter proposal to abandon hypothesis tests is worse. We still have plenty of interesting hypotheses to test: did human influence on climate increase the risk of this event at all? Did it increase it by more than a factor of two?”

Ministro participa da inauguração de radar meteorológico do Ceará (Ascom do governo do Ceará)

JC e-mail 4378, de 04 de Novembro de 2011.

Aloizio Mercadante e o governador do Ceará, Cid Gomes, inauguraram o Radar Meteorológico Banda-S, em Quixeramobim (CE). Equipamento ajudará na previsão de secas e cheias.

Previsão de secas e cheias, mudanças climáticas e todos os eventos ligados a meteorologia passam a ser informados pela Fundação Cearense de Meteorologia e Recursos Hídricos (Funceme) com mais previsão, já que agora o órgão conta com um novo equipamento para captação dessas informações.

O novo Radar Meteorológico Banda-S foi inaugurado nesta quinta-feira (3) pelo governador Cid Gomes e o ministro da Ciência e Tecnologia, Aloizio Mercadante. Localizado no Morro de Santa Maria, em Quixeramobim, no Sertão Central, o equipamento vai funcionar como parte da Rede Cearense de Radares (RCR), por meio da integração com o Radar Doppler de Banda X instalado em Fortaleza. “Parece um equipamento aparentemente simples, mas por trás existe uma utilidade inimaginável. A tecnologia pode ser um aliado na melhoria da qualidade de vida da população, que é o nosso compromisso”, destacou Cid Gomes durante a inauguração.

Segundo explicou o governador, o novo equipamento pode informar condições climáticas bem específicas, como por exemplo “que no município de Nova Olinda, no Cariri, choveu cinco milímetros”, exemplificou. “Na medida que uma informação dessas é casada com outras, isso vai ajudar a diagnosticar por exemplo um período de seca ou de cheias. Somos um estado com quase 300 mil pequenos agricultores, e eles precisam de informações concretas para cuidar da colheita. E nisso o Radar vai ser bastante útil”, ressaltou Cid Gomes.

O Radar Banda-S tem capacidade para estimar uma precipitação dentro de um raio de 200 quilômetros. Além disso, pode fazer o monitoramento de sistemas meteorológicos que atuam em um alcance de até 400 quilômetros. Por sua capacidade e localização, também será possível obter informações não só do Ceará, como de vários estados nordestinos. “Esse é um instrumento de planejamento agrícola que vai beneficiar também muitos estados do Nordeste, como Paraíba, Pernambuco, Piauí e Rio Grande do Norte”, lembrou Aloizio Mercadante. O ministro também ressaltou sua importância na prevenção de desastres naturais, como longos períodos de seca ou chuvas bem acima da média. “Precisamos entender porque esses eventos acontecem e prevenir as ações que as mudanças climáticas podem causar”, explicou Mercadante.

Para a instalação do Radar Meteorológico Banda-S foram investidos R$ 14 milhões, sendo R$ 10 milhões partiram do Governo Federal, por meio do Ministério da Ciência e Tecnologia e Inovação (MCTI) e R$ 4 milhões do governo do estado do Ceará. Do total, R$ 12 milhões foram utilizados para a compra do equipamento e o restante (R$ 2 milhões) para a melhoria dos acessos ao local (construção de vias) e alimentação energética.

Segundo lembrou o secretário estadual da Ciência e Tecnologia, René Barreira, a instalação do Radar partiu de uma emenda de Ciro Gomes quando deputado federal, que aliado a sensibilidade do ex-presidente Lula, tornou possível a obra. “Com esse importante equipamento vamos ter um zoneamento agrícola e um controle mais efetivo e técnico dos eventos de grande risco”, ressaltou o secretário.

Fraud Case Seen as a Red Flag for Psychology Research (N.Y. Times)

By BENEDICT CAREY

Published: November 2, 2011

A well-known psychologist in the Netherlands whose work has been published widely in professional journals falsified data and made up entire experiments, an investigating committee has found. Experts say the case exposes deep flaws in the way science is done in a field,psychology, that has only recently earned a fragile respectability.

The psychologist Diederik Stapel in an undated photograph. “I have failed as a scientist and researcher,” he said in a statement after a committee found problems in dozens of his papers.

The psychologist, Diederik Stapel, of Tilburg University, committed academic fraud in “several dozen” published papers, many accepted in respected journals and reported in the news media, according to a report released on Monday by the three Dutch institutions where he has worked: the University of Groningen, the University of Amsterdam, and Tilburg. The journal Science, which published one of Dr. Stapel’s papers in April, posted an “editorial expression of concern” about the research online on Tuesday.

The scandal, involving about a decade of work, is the latest in a string of embarrassments in a field that critics and statisticians say badly needs to overhaul how it treats research results. In recent years, psychologists have reported a raft of findings on race biases, brain imaging and even extrasensory perception that have not stood up to scrutiny. Outright fraud may be rare, these experts say, but they contend that Dr. Stapel took advantage of a system that allows researchers to operate in near secrecy and massage data to find what they want to find, without much fear of being challenged.

“The big problem is that the culture is such that researchers spin their work in a way that tells a prettier story than what they really found,” said Jonathan Schooler, a psychologist at the University of California, Santa Barbara. “It’s almost like everyone is on steroids, and to compete you have to take steroids as well.”

In a prolific career, Dr. Stapel published papers on the effect of power on hypocrisy, on racial stereotyping and on how advertisements affect how people view themselves. Many of his findings appeared in newspapers around the world, including The New York Times, which reported in December on his study about advertising and identity.

In a statement posted Monday on Tilburg University’s Web site, Dr. Stapel apologized to his colleagues. “I have failed as a scientist and researcher,” it read, in part. “I feel ashamed for it and have great regret.”

More than a dozen doctoral theses that he oversaw are also questionable, the investigators concluded, after interviewing former students, co-authors and colleagues. Dr. Stapel has published about 150 papers, many of which, like the advertising study, seem devised to make a splash in the media. The study published in Science this year claimed that white people became more likely to “stereotype and discriminate” against black people when they were in a messy environment, versus an organized one. Another study, published in 2009, claimed that people judged job applicants as more competent if they had a male voice. The investigating committee did not post a list of papers that it had found fraudulent.

Dr. Stapel was able to operate for so long, the committee said, in large measure because he was “lord of the data,” the only person who saw the experimental evidence that had been gathered (or fabricated). This is a widespread problem in psychology, said Jelte M. Wicherts, a psychologist at the University of Amsterdam. In a recent survey, two-thirds of Dutch research psychologists said they did not make their raw data available for other researchers to see. “This is in violation of ethical rules established in the field,” Dr. Wicherts said.

In a survey of more than 2,000 American psychologists scheduled to be published this year, Leslie John of Harvard Business School and two colleagues found that 70 percent had acknowledged, anonymously, to cutting some corners in reporting data. About a third said they had reported an unexpected finding as predicted from the start, and about 1 percent admitted to falsifying data.

Also common is a self-serving statistical sloppiness. In an analysis published this year, Dr. Wicherts and Marjan Bakker, also at the University of Amsterdam, searched a random sample of 281 psychology papers for statistical errors. They found that about half of the papers in high-end journals contained some statistical error, and that about 15 percent of all papers had at least one error that changed a reported finding — almost always in opposition to the authors’ hypothesis.

The American Psychological Association, the field’s largest and most influential publisher of results, “is very concerned about scientific ethics and having only reliable and valid research findings within the literature,” said Kim I. Mills, a spokeswoman. “We will move to retract any invalid research as such articles are clearly identified.”

Researchers in psychology are certainly aware of the issue. In recent years, some have mocked studies showing correlations between activity on brain images and personality measures as “voodoo” science, and a controversy over statistics erupted in January after The Journal of Personality and Social Psychology accepted a paper purporting to show evidence of extrasensory perception. In cases like these, the authors being challenged are often reluctant to share their raw data. But an analysis of 49 studies appearing Wednesday in the journal PLoS One, by Dr. Wicherts, Dr. Bakker and Dylan Molenaar, found that the more reluctant that scientists were to share their data, the more likely that evidence contradicted their reported findings.

“We know the general tendency of humans to draw the conclusions they want to draw — there’s a different threshold,” said Joseph P. Simmons, a psychologist at the University of Pennsylvania’s Wharton School. “With findings we want to see, we ask, ‘Can I believe this?’ With those we don’t, we ask, ‘Must I believe this?’ ”

But reviewers working for psychology journals rarely take this into account in any rigorous way. Neither do they typically ask to see the original data. While many psychologists shade and spin, Dr. Stapel went ahead and drew any conclusion he wanted.

“We have the technology to share data and publish our initial hypotheses, and now’s the time,” Dr. Schooler said. “It would clean up the field’s act in a very big way.”

Mathematically Detecting Stock Market Bubbles Before They Burst (Science Daily)

ScienceDaily (Oct. 31, 2011) — From the dotcom bust in the late nineties to the housing crash in the run-up to the 2008 crisis, financial bubbles have been a topic of major concern. Identifying bubbles is important in order to prevent collapses that can severely impact nations and economies.

A paper published this month in the SIAM Journal on Financial Mathematics addresses just this issue. Opening fittingly with a quote from New York Federal Reserve President William Dudley emphasizing the importance of developing tools to identify and address bubbles in real time, authors Robert Jarrow, Younes Kchia, and Philip Protter propose a mathematical model to detect financial bubbles.

A financial bubble occurs when prices for assets, such as stocks, rise far above their actual value. Such an economic cycle is usually characterized by rapid expansion followed by a contraction, or sharp decline in prices.

“It has been hard not to notice that financial bubbles play an important role in our economy, and speculation as to whether a given risky asset is undergoing bubble pricing has approached the level of an armchair sport. But bubbles can have real and often negative consequences,” explains Protter, who has spent many years studying and analyzing financial markets.

“The ability to tell when an asset is or is not in a bubble could have important ramifications in the regulation of the capital reserves of banks as well as for individual investors and retirement funds holding assets for the long term. For banks, if their capital reserve holdings include large investments with unrealistic values due to bubbles, a shock to the bank could occur when the bubbles burst, potentially causing a run on the bank, as infamously happened with Lehman Brothers, and is currently happening with Dexia, a major European bank,” he goes on to explain, citing the significance of such inflated prices.

Using sophisticated mathematical methods, Protter and his co-authors answer the question of whether the price increase of a particular asset represents a bubble in real time. “[In this paper] we show that by using tick data and some statistical techniques, one is able to tell with a large degree of certainty, whether or not a given financial asset (or group of assets) is undergoing bubble pricing,” says Protter.

This question is answered by estimating an asset’s price volatility, which is stochastic or randomly determined. The authors define an asset’s price process in terms of a standard stochastic differential equation, which is driven by Brownian motion. Brownian motion, based on a natural process involving the erratic, random movement of small particles suspended in gas or liquid, has been widely used in mathematical finance. The concept is specifically used to model instances where previous change in the value of a variable is unrelated to past changes.

The key characteristic in determining a bubble is the volatility of an asset’s price, which, in the case of bubbles is very high. The authors estimate the volatility by applying state of the art estimators to real-time tick price data for a given stock. They then obtain the best possible extension of this data for large values using a technique called Reproducing Kernel Hilbert Spaces (RKHS), which is a widely used method for statistical learning.

“First, one uses tick price data to estimate the volatility of the asset in question for various levels of the asset’s price,” Protter explains. “Then, a special technique (RKHS with an optimization addition) is employed to extrapolate this estimated volatility function to large values for the asset’s price, where this information is not (and cannot be) available from tick data. Using this extrapolation, one can check the rate of increase of the volatility function as the asset price gets arbitrarily large. Whether or not there is a bubble depends on how fast this increase occurs (its asymptotic rate of increase).”

If it does not increase fast enough, there is no bubble within the model’s framework.

The authors test their methodology by applying the model to several stocks from the dot-com bubble of the nineties. They find fairly successful rates in their predictions, with higher accuracies in cases where market volatilities can be modeled more efficiently. This helps establish the strengths and weaknesses of the method.

The authors have also used the model to test more recent price increases to detect bubbles. “We have found, for example, that the IPO [initial public offering] of LinkedIn underwent bubble pricing at its debut, and that the recent rise in gold prices was not a bubble, according to our models,” Protter says.

It is encouraging to see that mathematical analysis can play a role in the diagnosis and detection of bubbles, which have significantly impacted economic upheavals in the past few decades.

O futuro da ciência está na colaboração (Valor Econômico)

JC e-mail 4376, de 01 de Novembro de 2011.

Texto de Michael Nielsen publicado no The Wall Street Journal e divulgado pelo Valor Econômico.

Um matemático da Universidade de Cambridge chamado Tim Gowers decidiu em janeiro de 2009 usar seu blog para realizar um experimento social inusitado. Ele escolheu um problema matemático difícil e tentou resolvê-lo abertamente, usando o blog para apresentar suas ideias e como estava progredindo. Ele convidou todo mundo para contribuir com ideias, na esperança de que várias mentes unidas seriam mais poderosas que uma. Ele chamou o experimento de Projeto Polímata (“Polymath Project”).

Quinze minutos depois de Gowers abrir o blog para discussão, um matemático húngaro-canadense publicou um comentário. Quinze minutos depois, um professor de matemática do ensino médio dos Estados Unidos entrou na conversa. Três minutos depois disso, o matemático Terence Tao, da Universidade da Califórnia em Los Angeles, também comentou. A discussão pegou fogo e em apenas seis semanas o problema foi solucionado.

Embora tenham surgido outros desafios e os colaboradores dessa rede nem sempre tenham encontrado todas as soluções, eles conseguiram criar uma nova abordagem para solucionar problemas. O trabalho deles é um exemplo das experiências com ciência colaborativa que estão sendo feitas para estudar desde de galáxias até dinossauros.

Esses projetos usam a internet como ferramenta cognitiva para amplificar a inteligência coletiva. Essas ferramentas são um meio de conectar as pessoas certas com os problemas certos na hora certa, ativando o que é um conhecimento apenas latente.

A colaboração em rede tem o potencial de acelerar extraordinariamente o número de descobertas da ciência como um todo. É provável que assistiremos a uma mudança mais fundamental na pesquisa científica nas próximas décadas do que a ocorrida nos últimos três séculos.

Mas há obstáculos grandes para alcançar essa meta. Embora pareça natural que os cientistas adotem essas novas ferramentas de descobrimento, na verdade eles têm demonstrado uma inibição surpreendente. Iniciativas como o Projeto Polímata continuam sendo exceção, não regra.

Considere a simples ideia de compartilhar dados científicos on-line. O melhor exemplo disso é o projeto do genoma humano, cujos dados podem ser baixados por qualquer um. Quando se lê no noticiário que um certo gene foi associado a alguma doença, é praticamente certo que é uma descoberta possibilitada pela política do projeto de abrir os dados.

Apesar do valor enorme de divulgar abertamente os dados, a maioria dos laboratórios não faz um esforço sistemático para compartilhar suas informações com outros cientistas. Como me disse um biólogo, ele estava “sentado no genoma” de uma nova espécie inteira há mais de um ano. Uma espécie inteira! Imagine as descobertas cruciais que outros cientistas poderiam ter feito se esse genoma tivesse sido carregado num banco de dados aberto.

Por que os cientistas não gostam de compartilhar?

Se você é um cientista buscando um emprego ou financiamento de pesquisa, o maior fator para determinar seu sucesso será o número de publicações científicas que já conseguiu. Se o seu histórico for brilhante, você se dará bem. Se não for, terá problemas. Então você dedica seu cotidiano de trabalho à produção de artigos para revistas acadêmicas.

Mesmo que ache pessoalmente que seria muito melhor para a ciência como um todo se você organizasse e compartilhasse seus dados na internet, é um tempo que o afasta do “verdadeiro” trabalho de escrever os artigos. Compartilhar dados não é algo a que seus colegas vão dar crédito, exceto em poucas áreas.

Há outras áreas em que os cientistas ainda estão atrasados no uso das ferramentas on-line. Um exemplo são os “wikis” criadas por pioneiros corajosos em assuntos como computação quântica, teoria das cordas e genética (um wiki permite o compartilhamento e edição colaborativa de um conjunto de informações interligadas, e o site Wikipedia é o mais conhecido deles).

Os wikis especializados podem funcionar como obras de referência atualizadas sobre as pesquisas mais recentes de um campo, como se fossem livros didáticos que evoluem ultrarrápido. Eles podem incluir descrições de problemas científicos importantes que ainda não foram resolvidos e podem servir de ferramenta para encontrar soluções.

Mas a maioria desses wikis não deu certo. Eles têm o mesmo problema que o compartilhamento de dados: mesmo se os cientistas acreditarem no valor da colaboração, sabem que escrever um único artigo medíocre fará muito mais por suas carreiras. O incentivo está completamente errado.

Para a ciência em rede alcançar seu potencial, os cientistas precisam abraçar e recompensar o compartilhamento aberto de todos os conhecimentos científicos, não só o publicado nas revistas acadêmicas tradicionais. A ciência em rede precisa ser aberta.

The world at seven billion (BBC)

27 October 2011 Last updated at 23:08 GMT

File photograph of newborn babies in Lucknow, India, in July 2009

As the world population reaches seven billion people, the BBC’s Mike Gallagher asks whether efforts to control population have been, as some critics claim, a form of authoritarian control over the world’s poorest citizens.

The temperature is some 30C. The humidity stifling, the noise unbearable. In a yard between two enormous tea-drying sheds, a number of dark-skinned women patiently sit, each accompanied by an unwieldy looking cloth sack. They are clad in colourful saris, but look tired and shabby. This is hardly surprising – they have spent most of the day in nearby plantation fields, picking tea that will net them around two cents a kilo – barely enough to feed their large families.

Vivek Baid thinks he knows how to help them. He runs the Mission for Population Control, a project in eastern India which aims to bring down high birth rates by encouraging local women to get sterilised after their second child.

As the world reaches an estimated seven billion people, people like Vivek say efforts to bring down the world’s population must continue if life on Earth is to be sustainable, and if poverty and even mass starvation are to be avoided.

There is no doubting their good intentions. Vivek, for instance, has spent his own money on the project, and is passionate about creating a brighter future for India.

But critics allege that campaigners like Vivek – a successful and wealthy male businessman – have tended to live very different lives from those they seek to help, who are mainly poor women.

These critics argue that rich people have imposed population control on the poor for decades. And, they say, such coercive attempts to control the world’s population often backfired and were sometimes harmful.

Population scare

Most historians of modern population control trace its roots back to the Reverend Thomas Malthus, an English clergyman born in the 18th Century who believed that humans would always reproduce faster than Earth’s capacity to feed them.

Giving succour to the resulting desperate masses would only imperil everyone else, he said. So the brutal reality was that it was better to let them starve.

‘Plenty is changed into scarcity’

Thomas Malthus

From Thomas Malthus’ Essay on Population, 1803 edition:

A man who is born into a world already possessed – if he cannot get subsistence from his parents on whom he has a just demand, and if the society do not want his labour, has no claim of right to the smallest portion of food.

At nature’s mighty feast there is no vacant cover for him. She tells him to be gone, and will quickly execute her own orders, if he does not work upon the compassion of some of her guests. If these guests get up and make room for him, other intruders immediately appear demanding the same favour. The plenty that before reigned is changed into scarcity; and the happiness of the guests is destroyed by the spectacle of misery and dependence in every part of the hall.

Rapid agricultural advances in the 19th Century proved his main premise wrong, because food production generally more than kept pace with the growing population.

But the idea that the rich are threatened by the desperately poor has cast a long shadow into the 20th Century.

From the 1960s, the World Bank, the UN and a host of independent American philanthropic foundations, such as the Ford and Rockefeller foundations, began to focus on what they saw as the problem of burgeoning Third World numbers.

The believed that overpopulation was the primary cause of environmental degradation, economic underdevelopment and political instability.

Massive populations in the Third World were seen as presenting a threat to Western capitalism and access to resources, says Professor Betsy Hartmann of Hampshire College, Massachusetts, in the US.

“The view of the south is very much put in this Malthusian framework. It becomes just this powerful ideology,” she says.

In 1966, President Lyndon Johnson warned that the US might be overwhelmed by desperate masses, and he made US foreign aid dependent on countries adopting family planning programmes.

Other wealthy countries such as Japan, Sweden and the UK also began to devote large amounts of money to reducing Third World birth rates.

‘Unmet need’

What virtually everyone agreed was that there was a massive demand for birth control among the world’s poorest people, and that if they could get their hands on reliable contraceptives, runaway population growth might be stopped.

But with the benefit of hindsight, some argue that this so-called unmet need theory put disproportionate emphasis on birth control and ignored other serious needs.

“It was a top-down solution,” says Mohan Rao, a doctor and public health expert at Delhi’s Jawaharlal Nehru University.

“There was an unmet need for contraceptive services, of course. But there was also an unmet need for health services and all kinds of other services which did not get attention. The focus became contraception.”

Had the demographic experts worked at the grass-roots instead of imposing solutions from above, suggests Adrienne Germain, formerly of the Ford Foundation and then the International Women’s Health Coalition, they might have achieved a better picture of the dilemmas facing women in poor, rural communities.

“Not to have a full set of health services meant women were either unable to use family planning, or unwilling to – because they could still expect half their kids to die by the age of five,” she says.

India’s sterilisation ‘madness’

Indira Gandhi and her son Sanjay (above) presided over a mass sterilisation campaign. From the mid-1970s, Indian officials were set sterilisation quotas, and sought to ingratiate themselves with superiors by exceeding them. Stories abounded of men being accosted in the street and taken away for the operation. The head of the World Bank, Robert McNamara, congratulated the Indian government on “moving effectively” to deal with high birth rates. Funding was increased, and the sterilising went on.

In Delhi, some 700,000 slum dwellers were forcibly evicted, and given replacement housing plots far from the city centre, frequently on condition that they were either sterilised or produced someone else for the operation. In poorer agricultural areas, whole villages were rounded up for sterilisation. When residents of one village protested, an official is said to have threatened air strikes in retaliation.

“There was a certain madness,” recalls Nina Puri of the Family Planning Association of India. “All rationality was lost.”

Us and them

In 1968, the American biologist Paul Ehrlich caused a stir with his bestselling book, The Population Bomb, which suggested that it was already too late to save some countries from the dire effects of overpopulation, which would result in ecological disaster and the deaths of hundreds of millions of people in the 1970s.

Instead, governments should concentrate on drastically reducing population growth. He said financial assistance should be given only to those nations with a realistic chance of bringing birth rates down. Compulsory measures were not to be ruled out.

Western experts and local elites in the developing world soon imposed targets for reductions in family size, and used military analogies to drive home the urgency, says Matthew Connelly, a historian of population control at Columbia University in New York.

“They spoke of a war on population growth, fought with contraceptive weapons,” he says. “The war would entail sacrifices, and collateral damage.”

Such language betrayed a lack of empathy with their subjects, says Ms Germain: “People didn’t talk about people. They talked of acceptors and users of family planning.”

Emergency measures

Critics of population control had their say at the first ever UN population conference in 1974.

Karan Singh, India’s health minister at the time, declared that “development is the best contraceptive”.

But just a year later, Mr Singh’s government presided over one of the most notorious episodes in the history of population control.

In June 1975, the Indian premier, Indira Gandhi, declared a state of emergency after accusations of corruption threatened her government. Her son Sanjay used the measure to introduce radical population control measures targeted at the poor.

The Indian emergency lasted less than two years, but in 1975 alone, some eight million Indians – mainly poor men – were sterilised.

Yet, for all the official programmes and coercion, many poor women kept on having babies.

And where they did not, it arguably had less to do with coercive population control than with development, just as Karan Singh had argued in 1974, says historian Matt Connelly.

For example, in India, a disparity in birth rates could already be observed between the impoverished northern states and more developed southern regions like Kerala, where women were more likely to be literate and educated, and their offspring more likely to be healthy.

Women there realised that they could have fewer births and still expect to see their children survive into adulthood.

China: ‘We will not allow your baby to live’

Steven Mosher was a Stanford University anthropologist working in rural China who witnessed some of the early, disturbing moments of Beijing’s One Child Policy.

“I remember very well the evening of 8 March, 1980. The local Communist Party official in charge of my village came over waving a government document. He said: ‘The Party has decided to impose a cap of 1% on population growth this year.’ He said: ‘We’re going to decide who’s going to be allowed to continue their pregnancy and who’s going to be forced to terminate their pregnancy.’ And that’s exactly what they did.”

“These were women in the late second and third trimester of pregnancy. There were several women just days away from giving birth. And in my hearing, a party official said: ‘Do not think that you can simply wait until you go into labour and give birth, because we will not allow your baby to live. You will go home alone’.”

Total control

By now, this phenomenon could be observed in another country too – one that would nevertheless go on to impose the most draconian population control of all.

The One Child Policy is credited with preventing some 400 million births in China, and remains in place to this day. In 1983 alone, more than 16 million women and four million men were sterilised, and 14 million women received abortions.

Assessed by numbers alone, it is said to be by far the most successful population control initiative. Yet it remains deeply controversial, not only because of the human suffering it has caused.

A few years after its inception, the policy was relaxed slightly to allow rural couples two children if their first was not a boy. Boy children are prized, especially in the countryside where they provide labour and care for parents in old age.

But modern technology allows parents to discover the sex of the foetus, and many choose to abort if they are carrying a girl. In some regions, there is now a serious imbalance between men and women.

Moreover, since Chinese fertility was already in decline at the time the policy was implemented, some argue that it bears less responsibility for China’s falling birth rate than its supporters claim.

“I don’t think they needed to bring it down further,” says Indian demographer AR Nanda. “It would have happened at its own slow pace in another 10 years.”

Backlash

In the early 1980s, objections to the population control movement began to grow, especially in the United States.

In Washington, the new Reagan administration removed financial support for any programmes that involved abortion or sterilisation.

“If you give women the tools they need – education, employment, contraception, safe abortion – then they will make the choices that benefit society”

Adrienne Germain

The broad alliance to stem birth rates was beginning to dissolve and the debate become more polarised along political lines.

While some on the political right had moral objections to population control, some on the left saw it as neo-colonialism.

Faith groups condemned it as a Western attack on religious values, but women’s groups feared changes would mean poor women would be even less well-served.

By the time of a major UN conference on population and development in Cairo in 1994, women’s groups were ready to strike a blow for women’s rights, and they won.

The conference adopted a 20-year plan of action, known as the Cairo consensus, which called on countries to recognise that ordinary women’s needs – rather than demographers’ plans – should be at the heart of population strategies.

After Cairo

Today’s record-breaking global population hides a marked long-term trend towards lower birth rates, as urbanisation, better health care, education and access to family planning all affect women’s choices.

With the exception of sub-Saharan Africa and some of the poorest parts of India, we are now having fewer children than we once did – in some cases, failing even to replace ourselves in the next generation. And although total numbers are set to rise still further, the peak is now in sight.

Assuming that this trend continues, total numbers will one day level off, and even fall. As a result, some believe the sense of urgency that once surrounded population control has subsided.

The term population control itself has fallen out of fashion, as it was deemed to have authoritarian connotations. Post-Cairo, the talk is of women’s rights and reproductive rights, meaning the right to a free choice over whether or not to have children.

According to Adrienne Germain, that is the main lesson we should learn from the past 50 years.

“I have a profound conviction that if you give women the tools they need – education, employment, contraception, safe abortion – then they will make the choices that benefit society,” she says.

“If you don’t, then you’ll just be in an endless cycle of trying to exert control over fertility – to bring it up, to bring it down, to keep it stable. And it never comes out well. Never.”

Nevertheless, there remain to this day schemes to sterilise the less well-off, often in return for financial incentives. In effect, say critics, this amounts to coercion, since the very poor find it hard to reject cash.

“The people proposing this argue ‘Don’t worry, everything’ s fine now we have voluntary programmes on the Cairo model’,” says Betsy Hartmann.

“But what they don’t understand is the profound difference in power between rich and poor. The people who provide many services in poor areas are already prejudiced against the people they serve.”

Work in progress

For Mohan Rao, it is an example of how even the Cairo consensus fails to take account of the developing world.

“Cairo had some good things,” he says. “However Cairo was driven largely by First World feminist agendas. Reproductive rights are all very well, but [there needs to be] a whole lot of other kinds of enabling rights before women can access reproductive rights. You need rights to food, employment, water, justice and fair wages. Without all these you cannot have reproductive rights.”

Perhaps, then, the humanitarian ideals of Cairo are still a work in progress.

Meanwhile, Paul Ehrlich has also amended his view of the issue.

If he were to write his book today, “I wouldn’t focus on the poverty-stricken masses”, he told the BBC.

“I would focus on there being too many rich people. It’s crystal clear that we can’t support seven billion people in the style of the wealthier Americans.”

Demography

A tale of three islands

Oct 22nd 2011 | from the print edition

 

IN 1950 the whole population of the earth—2.5 billion—could have squeezed, shoulder to shoulder, onto the Isle of Wight, a 381-square-kilometre rock off southern England. By 1968 John Brunner, a British novelist, observed that the earth’s people—by then 3.5 billion—would have required the Isle of Man, 572 square kilometres in the Irish Sea, for its standing room. Brunner forecast that by 2010 the world’s population would have reached 7 billion, and would need a bigger island. Hence the title of his 1968 novel about over-population, “Stand on Zanzibar” (1,554 square kilometres off east Africa).

Brunner’s prediction was only a year out. The United Nations’ population division now says the world will reach 7 billion on October 31st 2011 (America’s Census Bureau delays the date until March 2012). The UN will even identify someone born that day as the world’s 7 billionth living person. The 6 billionth, Adnan Nevic, was born on October 12th 1999 in Sarajevo, in Bosnia. He will be just past his 12th birthday when the next billion clicks over.

That makes the world’s population look as if it is rising as fast as ever. It took 250,000 years to reach 1 billion, around 1800; over a century more to reach 2 billion (in 1927); and 32 years more to reach 3 billion. But to rise from 5 billion (in 1987) to 6 billion took only 12 years; and now, another 12 years later, it is at 7 billion (see chart 1). By 2050, the UN thinks, there will be 9.3 billion people, requiring an island the size of Tenerife or Maui to stand on.

Odd though it seems, however, the growth in the world’s population is actually slowing. The peak of population growth was in the late 1960s, when the total was rising by almost 2% a year. Now the rate is half that. The last time it was so low was in 1950, when the death rate was much higher. The result is that the next billion people, according to the UN, will take 14 years to arrive, the first time that a billion milestone has taken longer to reach than the one before. The billion after that will take 18 years.

Once upon a time, the passing of population milestones might have been cause for celebration. Now it gives rise to jeremiads. As Hillary Clinton’s science adviser, Nina Fedoroff, told the BBC in 2009, “There are probably already too many people on the planet.” But the notion of “too many” is more flexible than it seems. The earth could certainly not support 10 billion hunter-gatherers, who used much more land per head than modern farm-fed people do. But it does not have to. The earth might well not be able to support 10 billion people if they had exactly the same impact per person as 7 billion do today. But that does not necessarily spell Malthusian doom, because the impact humans have on the earth and on each other can change.

For most people, the big questions about population are: can the world feed 9 billion mouths by 2050? Are so many people ruining the environment? And will those billions, living cheek-by-jowl, go to war more often? On all three counts, surprising as it seems, reducing population growth any more quickly than it is falling anyway may not make much difference.

Start with the link between population and violence. It seems plausible that the more young men there are, the more likely they will be to fight. This is especially true when groups are competing for scarce resources. Some argue that the genocidal conflict in Darfur, western Sudan, was caused partly by high population growth, which led to unsustainable farming and conflicts over land and water. Land pressure also influenced the Rwandan genocide of 1994, as migrants in search of a livelihood in one of the world’s most densely populated countries moved into already settled areas, with catastrophic results.

But there is a difference between local conflicts and what is happening on a global scale. Although the number of sovereign states has increased almost as dramatically as the world’s population over the past half-century, the number of wars between states fell fairly continuously during the period. The number of civil wars rose, then fell. The number of deaths in battle fell by roughly three-quarters. These patterns do not seem to be influenced either by the relentless upward pressure of population, or by the slackening of that pressure as growth decelerates. The difference seems to have been caused by fewer post-colonial wars, the ending of cold-war alliances (and proxy wars) and, possibly, the increase in international peacekeepers.

More people, more damage?

Human activity has caused profound changes to the climate, biodiversity, oceanic acidity and greenhouse-gas levels in the atmosphere. But it does not automatically follow that the more people there are, the worse the damage. In 2007 Americans and Australians emitted almost 20 tonnes of carbon dioxide each. In contrast, more than 60 countries—including the vast majority of African ones—emitted less than 1 tonne per person.

This implies that population growth in poorer countries (where it is concentrated) has had a smaller impact on the climate in recent years than the rise in the population of the United States (up by over 50% in 1970-2010). Most of the world’s population growth in the next 20 years will occur in countries that make the smallest contribution to greenhouse gases. Global pollution will be more affected by the pattern of economic growth—and especially whether emerging nations become as energy-intensive as America, Australia and China.

Population growth does make a bigger difference to food. All things being equal, it is harder to feed 7 billion people than 6 billion. According to the World Bank, between 2005 and 2055 agricultural productivity will have to increase by two-thirds to keep pace with rising population and changing diets. Moreover, according to the bank, if the population stayed at 2005 levels, farm productivity would have to rise by only a quarter, so more future demand comes from a growing population than from consumption per person.

Increasing farm productivity by a quarter would obviously be easier than boosting it by two-thirds. But even a rise of two-thirds is not as much as it sounds. From 1970-2010 farm productivity rose far more than this, by over three-and-a-half times. The big problem for agriculture is not the number of people, but signs that farm productivity may be levelling out. The growth in agricultural yields seems to be slowing down. There is little new farmland available. Water shortages are chronic and fertilisers are over-used. All these—plus the yield-reductions that may come from climate change, and wastefulness in getting food to markets—mean that the big problems are to do with supply, not demand.

None of this means that population does not matter. But the main impact comes from relative changes—the growth of one part of the population compared with another, for example, or shifts in the average age of the population—rather than the absolute number of people. Of these relative changes, falling fertility is most important. The fertility rate is the number of children a woman can expect to have. At the moment, almost half the world’s population—3.2 billion—lives in countries with a fertility rate of 2.1 or less. That number, the so-called replacement rate, is usually taken to be the level at which the population eventually stops growing.

The world’s decline in fertility has been staggering (see chart 2). In 1970 the total fertility rate was 4.45 and the typical family in the world had four or five children. It is now 2.45 worldwide, and lower in some surprising places. Bangladesh’s rate is 2.16, having halved in 20 years. Iran’s fertility fell from 7 in 1984 to just 1.9 in 2006. Countries with below-replacement fertility include supposedly teeming Brazil, Tunisia and Thailand. Much of Europe and East Asia have fertility rates far below replacement levels.

The fertility fall is releasing wave upon wave of demographic change. It is the main influence behind the decline of population growth and, perhaps even more important, is shifting the balance of age groups within a population.

When gold turns to silver

A fall in fertility sends a sort of generational bulge surging through a society. The generation in question is the one before the fertility fall really begins to bite, which in Europe and America was the baby-boom generation that is just retiring, and in China and East Asia the generation now reaching adulthood. To begin with, the favoured generation is in its childhood; countries have lots of children and fewer surviving grandparents (who were born at a time when life expectancy was lower). That was the situation in Europe in the 1950s and in East Asia in the 1970s.

But as the select generation enters the labour force, a country starts to benefit from a so-called “demographic dividend”. This happens when there are relatively few children (because of the fall in fertility), relatively few older people (because of higher mortality previously), and lots of economically active adults, including, often, many women, who enter the labour force in large numbers for the first time. It is a period of smaller families, rising income, rising life expectancy and big social change, including divorce, postponed marriage and single-person households. This was the situation in Europe between 1945 and 1975 (“les trente glorieuses”) and in much of East Asia in 1980-2010.

But there is a third stage. At some point, the gilded generation turns silver and retires. Now the dividend becomes a liability. There are disproportionately more old people depending upon a smaller generation behind them. Population growth stops or goes into reverse, parts of a country are abandoned by the young and the social concerns of the aged grow in significance. This situation already exists in Japan. It is arriving fast in Europe and America, and soon after that will reach East Asia.

A demographic dividend tends to boost economic growth because a large number of working-age adults increases the labour force, keeps wages relatively low, boosts savings and increases demand for goods and services. Part of China’s phenomenal growth has come from its unprecedentedly low dependency ratio—just 38 (this is the number of dependents, children and people over 65, per 100 working adults; it implies the working-age group is almost twice as large as the rest of the population put together). One study by Australia’s central bank calculated that a third of East Asia’s GDP growth in 1965-90 came from its favourable demography. About a third of America’s GDP growth in 2000-10 also came from its increasing population.

The world as a whole reaped a demographic dividend in the 40 years to 2010. In 1970 there were 75 dependents for every 100 adults of working age. In 2010 the number of dependents dropped to just 52. Huge improvements were registered not only in China but also in South-East Asia and north Africa, where dependency ratios fell by 40 points. Even “ageing” Europe and America ended the period with fewer dependents than at the beginning.

A demographic dividend does not automatically generate growth. It depends on whether the country can put its growing labour force to productive use. In the 1980s Latin America and East Asia had similar demographic patterns. But while East Asia experienced a long boom, Latin America endured its “lost decade”. One of the biggest questions for Arab countries, which are beginning to reap their own demographic dividends, is whether they will follow East Asia or Latin America.

But even if demography guarantees nothing, it can make growth harder or easier. National demographic inheritances therefore matter. And they differ a lot.

Where China loses

Hania Zlotnik, the head of the UN’s Population Division, divides the world into three categories, according to levels of fertility (see map). About a fifth of the world lives in countries with high fertility—3 or more. Most are Africans. Sub-Saharan Africa, for example, is one of the fastest-growing parts of the world. In 1975 it had half the population of Europe. It overtook Europe in 2004, and by 2050 there will be just under 2 billion people there compared with 720m Europeans. About half of the 2.3 billion increase in the world’s population over the next 40 years will be in Africa.

The rest of the world is more or less equally divided between countries with below-replacement fertility (less than 2.1) and those with intermediate fertility (between 2.1 and 3). The first group consists of Europe, China and the rest of East Asia. The second comprises South and South-East Asia, the Middle East and the Americas (including the United States).

The low-fertility countries face the biggest demographic problems. The elderly share of Japan’s population is already the highest in the world. By 2050 the country will have almost as many dependents as working-age adults, and half the population will be over 52. This will make Japan the oldest society the world has ever known. Europe faces similar trends, less acutely. It has roughly half as many dependent children and retired people as working-age adults now. By 2050 it will have three dependents for every four adults, so will shoulder a large burden of ageing, which even sustained increases in fertility would fail to reverse for decades. This will cause disturbing policy implications in the provision of pensions and health care, which rely on continuing healthy tax revenues from the working population.

At least these countries are rich enough to make such provision. Not so China. With its fertility artificially suppressed by the one-child policy, it is ageing at an unprecedented rate. In 1980 China’s median age (the point where half the population is older and half younger) was 22 years, a developing-country figure. China will be older than America as early as 2020 and older than Europe by 2030. This will bring an abrupt end to its cheap-labour manufacturing. Its dependency ratio will rise from 38 to 64 by 2050, the sharpest rise in the world. Add in the country’s sexual imbalances—after a decade of sex-selective abortions, China will have 96.5m men in their 20s in 2025 but only 80.3m young women—and demography may become the gravest problem the Communist Party has to face.

Many countries with intermediate fertility—South-East Asia, Latin America, the United States—are better off. Their dependency ratios are not deteriorating so fast and their societies are ageing more slowly. America’s demographic profile is slowly tugging it away from Europe. Though its fertility rate may have fallen recently, it is still slightly higher than Europe’s. In 2010 the two sides of the Atlantic had similar dependency rates. By 2050 America’s could be nearly ten points lower.

But the biggest potential beneficiaries are the two other areas with intermediate fertility—India and the Middle East—and the high-fertility continent of Africa. These places have long been regarded as demographic time-bombs, with youth bulges, poverty and low levels of education and health. But that is because they are moving only slowly out of the early stage of high fertility into the one in which lower fertility begins to make an impact.

At the moment, Africa has larger families and more dependent children than India or Arab countries and is a few years younger (its median age is 20 compared with their 25). But all three areas will see their dependency ratios fall in the next 40 years, the only parts of the world to do so. And they will keep their median ages low—below 38 in 2050. If they can make their public institutions less corrupt, keep their economic policies outward-looking and invest more in education, as East Asia did, then Africa, the Middle East and India could become the fastest-growing parts of the world economy within a decade or so.

Here’s looking at you

Demography, though, is not only about economics. Most emerging countries have benefited from the sort of dividend that changed Europe and America in the 1960s. They are catching up with the West in terms of income, family size and middle-class formation. Most say they want to keep their cultures unsullied by the social trends—divorce, illegitimacy and so on—that also affected the West. But the growing number of never-married women in urban Asia suggests that this will be hard.

If you look at the overall size of the world’s population, then, the picture is one of falling fertility, decelerating growth and a gradual return to the flat population level of the 18th century. But below the surface societies are being churned up in ways not seen in the much more static pre-industrial world. The earth’s population may never need a larger island than Maui to stand on. But the way it arranges itself will go on shifting for centuries to come.

Brasil já pesquisa efeitos da mudança do clima (Valor Econômico)

JC e-mail 4373, de 27 de Outubro de 2011.

As pesquisas em mudança climática no Brasil começam a mudar de rumo. Se há alguns anos o foco estava nos esforços de redução das emissões dos gases-estufa, agora miram a adaptação ao fenômeno.

“Sabemos que nos próximos cinco ou dez anos não há perspectiva para que seja firmado internacionalmente um acordo de redução nas emissões de gases-estufa de grandes proporções, com cortes entre 70% a 80%”, diz o físico Paulo Artaxo, da USP, um estudioso da Amazônia. “Esse panorama é cada vez mais longínquo. Portanto é fundamental que se estudem estratégias de adaptação.”

Em outras palavras, as pesquisas devem se voltar para os efeitos da mudança do clima nos ecossistemas, em ambientes urbanos, em contextos sociais. “Não é uma questão de dinheiro, mas de direcionamento dos estudos”, diz Artaxo, membro do conselho diretor do Painel Brasileiro de Mudança Climática, órgão científico ligado aos ministérios da Ciência e Tecnologia e Ambiente. “O País precisa se preparar mais adequadamente para a mudança climática.”

“É preciso pesquisar mais, por exemplo, as alterações no ciclo hidrológico”, cita Reynaldo Victoria, coordenador do Programa Fapesp de Pesquisa sobre Mudanças Climáticas Globais. “Saber onde vai chover mais e onde vai chover menos”, explica. É um dos braços da pesquisa de Artaxo na Amazônia. “Porque não se quer construir uma hidrelétrica onde choverá muito menos nas próximas décadas”, ilustra o físico.

O programa de mudança climática da Fapesp já conta com investimentos de US$ 30 milhões em projetos na área. É um dos braços mais novos da fundação, mas já está ganhando musculatura. Tem 21 projetos em andamento, 14 contratos novos, dois outros em parceria com instituições estrangeiras, como o britânico Natural Environment Research Council (Nerc) ou a francesa Agence Nationale de la Recherche (ANR). Em dez anos, a previsão é de investimentos de mais de R$ 100 milhões.

As pesquisas começam a se voltar para campos pouco estudados. “Vamos analisar questões críticas para o Brasil”, diz Artaxo. Ele cita, por exemplo, o ciclo de carbono na Amazônia – algo muito mais complexo do que estudar a fotossíntese e a respiração das plantas.

Victoria, que também é professor do Centro de Energia Nuclear Aplicada à Agricultura (Cena-USP), diz que a intenção do programa é mirar campos novos, como entender qual o papel do Atlântico Sul no clima da região Sul do Brasil e Norte da Argentina. Outro exemplo é obter registros históricos na área de paleoclima.

Os impactos na área de saúde também serão mais estudados. Já se sabe que a mudança do clima faz com que doenças que não existiam em determinado lugar, passem a ocorrer. A dengue, por exemplo, encontra ambiente propício em regiões mais quentes. Entre as novas pesquisas de doenças emergentes há o estudo de um tipo de leishmaniose, comum na Bolívia e no Peru, que não existia no Brasil e agora ameaça surgir no Acre. Provocada por um mosquito, a doença causa uma infecção cutânea e pode ser mortal.

Os pesquisadores falaram sobre seus projetos durante a Fapesp Week, evento que faz parte da comemoração pelos 50 anos da Fundação de Amparo à Pesquisa do Estado de São Paulo e terminou ontem, em Washington.

Limite próximo (Fapesp)

Amazônia está muito próxima de um ponto de não retorno para sua sobrevivência, diz Thomas Lovejoy, da George Mason University, no simpósio internacional FAPESP Week (foto: JVInfante Photography/Wilson Center)

27/10/2011

Agência FAPESP – A Amazônia está muito próxima de um ponto de não retorno para sua sobrevivência, devido a uma combinação de fatores que incluem aquecimento global, desflorestamento e queimadas que minam seu sistema hidrogeológico.

A advertência foi feita por Thomas Lovejoy, atualmente professor da George Mason University, no Estado de Virgínia, EUA, no primeiro dia do simpósio internacional FAPESP Week, em Washington, nesta segunda-feira.

O biólogo Lovejoy, um dos mais importantes especialistas em Amazônia do mundo, começou a trabalhar na floresta brasileira em 1965, “apenas três anos depois da fundação da FAPESP”, lembrou.

Apesar de muita coisa positiva ter acontecido nestes 47 anos (“quando pisei pela primeira vez em Belém, só havia uma floresta nacional e uma área indígena demarcada e quase nenhum cientista brasileiro se interessava em estudar a Amazônia; hoje esse situação está totalmente invertida”), também apareceram no período diversos fatores de preocupação.

Lovejoy acredita que restam cinco anos para inverter as tendências em tempo de evitar problemas de maior gravidade. O aquecimento da temperatura média do planeta já está na casa de 0,8 grau centígrado. Ele acredita que o limite aceitável é de 2 graus centígrados e que ele pode ser alcançado até 2016 se nada for feito para efetivamente reduzi-lo.

O objetivo fixado nas mais recentes reuniões sobre o clima em Cancun e Copenhague de limitar o aumento médio da temperatura média global em 2 graus centígrados pode ser insuficiente, na opinião de Lovejoy, devido a essa conjugação de elementos.

De forma similar, Lovejoy crê que 20% de desflorestamento em relação ao tamanho original da Amazônia é o máximo que ela consegue suportar e o atual índice já é de 17% (em 1965, a taxa era de 3%).

A boa notícia, diz o biólogo, é que há bastante terra abandonada, sem nenhuma perspectiva de utilização econômica na Amazônia e que pode ser de alguma forma reflorestada, o que poderia proporcionar certa margem de segurança.
