Reunião presencial marca fim da consulta pública do Plano Clima

A sociedade civil contribuiu, por meio de consulta pública, para a atualização do Plano Nacional sobre Mudança do Clima (Plano Clima), o principal instrumento para a implantação da Política Nacional sobre Mudança do Clima. A consulta pública eletrônica ficou aberta de 25 de setembro a 8 de novembro. Nessa quinta-feira (12) aconteceu a última reunião presencial. Durante o período, qualquer cidadão brasileiro pode oferecer suas contribuições, por meio do formulário disponível na internet. Do total de 27 formulários enviados, foram totalizadas 111 contribuições da consulta pública eletrônica. A versão final do plano revisado deve ser apresentada no primeiro trimestre de 2014.

O Ministério do Meio Ambiente (MMA) é o coordenador do Grupo Executivo (GEx) do Comitê Interministerial sobre Mudança do Clima (CIM). Apresentado em 2008 pelo governo federal, o Plano Clima visa incentivar o desenvolvimento e o aprimoramento das ações de mitigação no Brasil, colaborando com o esforço mundial de redução das emissões de gases de efeito estufa, bem como objetiva a criação das condições internas para lidar com os impactos da mudança global do clima (adaptação).

Avaliação

O secretário de Mudanças Climáticas e Qualidade Ambiental do MMA, Carlos Klink, destacou que a consulta pública permitiu incorporar os avanços que aconteceram no Brasil na questão de mudanças do clima e a suas articulações com a negociação internacional. “Isso mostra o tamanho da ambição que o tema mudanças do clima tem dentro do país, pois não é só uma questão internacional, mas também a sociedade brasileira está muito engajada”, enfatizou.

Klink lembra que existem nove planos para mitigação e já está sendo construído o Plano Nacional de Adaptação, previsto para ser concluído até 2015. O tema de mudanças do clima está em destaque no País. “Estamos nos tornando um exemplo internacionalmente e, aqui no Brasil, está criando raízes muito fortes em todos os setores da sociedade”, explicou. Para o secretário, a governança permite um diálogo para construção e elaboração de todos esses planos, com envolvimento de todos os setores dentro e fora do governo. “O documento reflete esse avanço e mostra de maneira sintética esse tremendo trabalho de coordenação”, salientou.

Etapas

A atualização do Plano Clima passou por várias etapas. Desde janeiro, foram realizadas 17 reuniões do Grupo Executivo e sete reuniões do Fórum Brasileiro de Mudanças Climáticas (FBMC). “O fórum é o canal entre a sociedade e o governo para essa questão clima, por isso a gente sempre estimulou que a sociedade usasse o Fórum nas discussões”, explicou o diretor de Climáticas do MMA, Adriano Santhiago.

Segundo ele, vários setores trouxeram contribuições que foram incorporadas no texto apresentado durante a consulta eletrônica. A contribuição da população foi encerrada nesta reunião presencial, na qual participaram representantes do governo, da academia, do setor produtivo e da sociedade civil. O próximo passo é uma discussão governamental para fechar o documento final.

Em 2009, o Congresso Nacional aprovou a Política Nacional sobre Mudança do Clima, com o ineditismo da adoção de vários compromissos nacionais voluntários de redução de emissões. Além disso, foi criado o Fundo Nacional sobre Mudança do Clima e lançados diversos planos setoriais. Outros pontos que merecem destaque são a redução substancial do desmatamento no país, a mudança do perfil das emissões nacionais de gases de efeito estufa e a transformação substantiva da forma como diversos setores, governamentais ou não, se engajaram no esforço para enfrentar a mudança do clima..

O Brasil na COP-19: mais do mesmo? (O Estado de S.Paulo)

JC e-mail 4872, de 10 de dezembro de 2013

Estadão publica artigo assinado por Pedro Motta Veiga e Sandra Polonia Rios

Nas negociações climáticas multilaterais, o Brasil é um ator central, mas que opera aquém de suas potencialidades, em razão de suas opções de política e estratégia negociadora. Exemplo disso foi a estratégia adotada pelo País na COP 19, de Varsóvia, realizada na segunda quinzena de novembro.

O País tem condições naturais e físicas que o colocam entre os principais atores na definição da governança global do clima. Mas as oportunidades que derivam da disponibilidade de capital físico e natural para uma estratégia de crescimento econômico sustentável não são capturadas pelas políticas públicas brasileiras. Esse déficit na incorporação da dimensão ambiental à formulação das políticas de desenvolvimento, combinado a uma histórica resistência a assumir compromissos internacionais que restringiriam a liberdade para implementar políticas públicas, leva a uma postura defensiva e pouco compatível com a posição que o Brasil pode ocupar nos foros multilaterais de negociação do clima.

O Brasil levou para essa COP duas propostas principais: 1) que o Painel Intergovernamental sobre Mudanças Climáticas (IPCC) crie uma metodologia que calcule a “culpa histórica” de cada nação no aumento da temperatura do planeta; e 2) que os governos façam consultas internas com setores da sociedade civil sobre as metas de redução de emissões de gases-estufa.

Não há nada de errado com o estímulo a que os países façam consultas públicas internas, mas a estratégia negociadora brasileira continua ancorada na defesa do princípio de responsabilidades comuns, mas diferenciadas, acordado em Kyoto e que levou ao estabelecimento de metas de redução de emissões de gases de efeito estufa apenas para os países desenvolvidos. É para apoiar a manutenção desse princípio que o Brasil defende a ideia de um levantamento da “culpa histórica” de cada nação no aumento de temperatura do planeta – levantamento cuja função seria servir de base para os compromissos que os países terão de assumir em 2015 para entrar em vigor em 2020. A ideia é de que os países desenvolvidos teriam produzido um estoque muito maior de emissões do que os países em desenvolvimento porque largaram na frente no processo de industrialização.

O tiro pode sair pela culatra. Um cálculo já realizado por um consórcio de respeitadas instituições internacionais – PBL Netherlands Environmental AssessmentAgency, Ecofys e EuropeanCommission’s Joint Research Centre1 (www.pbl.nl) – mostrou que a contribuição relativa dos países em desenvolvimento para as emissões acumuladas durante o período 1850-2010 foi de 48%. Para 2020, a previsão é de que a participação dos países em desenvolvimento ultrapasse a dos desenvolvidos, chegando a 51%.

Evidentemente, esses estudos envolvem decisões quanto a parâmetros e variáveis a serem incluídas. Assim, quando se desconta o progresso tecnológico das emissões históricas, para levar em consideração o fato de que os países em desenvolvimento se beneficiaram de tecnologias que foram desenvolvidas anteriormente pelos já industrializados, a contribuição histórica dos países em desenvolvimento para as emissões acumuladas sobe para 52%.

O fato é que a proposta de medir responsabilidades históricas acumuladas não parece contribuir em nada para superar o atual estado de impasse em que se encontram as negociações climáticas. Como se viu, essa proposta pode acabar contribuindo para reforçar a ideia de que, por causa de seu desempenho recente, os países em desenvolvimento serão em breve os maiores responsáveis – mesmo em termos acumulados – pelo aquecimento global.

Melhor fariam as autoridades brasileiras se buscassem adequar as políticas domésticas aos compromissos já assumidos na Política Nacional sobre Mudança do Clima, que é lei aprovada pelo Congresso Nacional (Lei n.º 12.187/2009). Isso permitiria ao País assumir o papel que lhe cabe na governança global do clima e aproveitar as oportunidades que essa agenda traz para o crescimento econômico.

New Long-Lived Greenhouse Gas Discovered: Highest Global-Warming Impact of Any Compound to Date (Science Daily)

Dec. 9, 2013 — Scientists from U of T’s Department of Chemistry have discovered a novel chemical lurking in the atmosphere that appears to be a long-lived greenhouse gas (LLGHG). The chemical — perfluorotributylamine (PFTBA) — is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate.

Radiative efficiency describes how effectively a molecule can affect climate. This value is then multiplied by its atmospheric concentration to determine the total climate impact.

PFTBA has been in use since the mid-20th century for various applications in electrical equipment and is currently used in thermally and chemically stable liquids marketed for use in electronic testing and as heat transfer agents. It does not occur naturally, that is, it is produced by humans. There are no known processes that would destroy or remove PFTBA in the lower atmosphere so it has a very long lifetime, possibly hundreds of years, and is destroyed in the upper atmosphere.

“Global warming potential is a metric used to compare the cumulative effects of different greenhouse gases on climate over a specified time period,” said Cora Young who was part of the U of T team, along with Angela Hong and their supervisor, Scott Mabury. Time is incorporated in the global warming potential metric as different compounds stay in the atmosphere for different lengths of time, which determines how long-lasting the climate impacts are.

Carbon dioxide (CO2) is used as the baseline for comparison since it is the most important greenhouse gas responsible for human-induced climate change. “PFTBA is extremely long-lived in the atmosphere and it has a very high radiative efficiency; the result of this is a very high global warming potential. Calculated over a 100-year timeframe, a single molecule of PFTBA has the equivalent climate impact as 7100 molecules of CO2,” said Hong.

Geoengineering Approaches to Reduce Climate Change Unlikely to Succeed (Science Daily)

Dec. 5, 2013 — Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all. Two German researchers used a simple energy balance analysis to explain how Earth’s water cycle responds differently to heating by sunlight than it does to warming due to a stronger atmospheric greenhouse effect. Further, they show that this difference implies that reflecting sunlight to reduce temperatures may have unwanted effects on Earth’s rainfall patterns.

The results are now published in Earth System Dynamics, an open access journal of the European Geosciences Union (EGU).

Global warming alters Earth’s water cycle since more water evaporates to the air as temperatures increase. Increased evaporation can dry out some regions while, at the same time, result in more rain falling in other areas due to the excess moisture in the atmosphere. The more water evaporates per degree of warming, the stronger the influence of increasing temperature on the water cycle. But the new study shows the water cycle does not react the same way to different types of warming.

Axel Kleidon and Maik Renner of the Max Planck Institute for Biogeochemistry in Jena, Germany, used a simple energy balance model to determine how sensitive the water cycle is to an increase in surface temperature due to a stronger greenhouse effect and to an increase in solar radiation. They predicted the response of the water cycle for the two cases and found that, in the former, evaporation increases by 2% per degree of warming while in the latter this number reaches 3%. This prediction confirmed results of much more complex climate models.

“These different responses to surface heating are easy to explain,” says Kleidon, who uses a pot on the kitchen stove as an analogy. “The temperature in the pot is increased by putting on a lid or by turning up the heat — but these two cases differ by how much energy flows through the pot,” he says. A stronger greenhouse effect puts a thicker ‘lid’ over Earth’s surface but, if there is no additional sunlight (if we don’t turn up the heat on the stove), extra evaporation takes place solely due to the increase in temperature. Turning up the heat by increasing solar radiation, on the other hand, enhances the energy flow through Earth’s surface because of the need to balance the greater energy input with stronger cooling fluxes from the surface. As a result, there is more evaporation and a stronger effect on the water cycle.

In the new Earth System Dynamics study the authors also show how these findings can have profound consequences for geoengineering. Many geoengineering approaches aim to reduce global warming by reducing the amount of sunlight reaching Earth’s surface (or, in the pot analogy, reduce the heat from the stove). But when Kleidon and Renner applied their results to such a geoengineering scenario, they found out that simultaneous changes in the water cycle and the atmosphere cannot be compensated for at the same time. Therefore, reflecting sunlight by geoengineering is unlikely to restore the planet’s original climate.

“It’s like putting a lid on the pot and turning down the heat at the same time,” explains Kleidon. “While in the kitchen you can reduce your energy bill by doing so, in the Earth system this slows down the water cycle with wide-ranging potential consequences,” he says.

Kleidon and Renner’s insight comes from looking at the processes that heat and cool Earth’s surface and how they change when the surface warms. Evaporation from the surface plays a key role, but the researchers also took into account how the evaporated water is transported into the atmosphere. They combined simple energy balance considerations with a physical assumption for the way water vapour is transported, and separated the contributions of surface heating from solar radiation and from increased greenhouse gases in the atmosphere to obtain the two sensitivities. One of the referees for the paper commented: “it is a stunning result that such a simple analysis yields the same results as the climate models.”

The India Problem (Slate)

Why is it thwarting every international climate agreement?

NOV. 27 2013 12:44 PM

By 

Haze in Mumbai, 2009

India has stalled international greenhouse gas accords because climate change isn’t a winning election issue in the developing country.

Apowerful but unpredictable force is rising in the battle over the future of the climate. It’s the type of powerful force that’s felt when 1.2 billion people clamor for more electricity—many of them trying to light, heat, and refrigerate their ways out of poverty; others throwing rupees at excessive air conditioning and other newfound luxuries. And it’s the type of unpredictable force that’s felt when the government of those 1.2 billion is in election mode, clamoring for votes by brazenly blocking progress at international climate talks.

Hundreds of millions of Indians live in poverty, wielding a tiny per-person carbon footprint when compared with residents of the West and coming out on top of environmental sustainability surveys. But the country is home to so many people that steady economic growth is turning it into a climate-changing powerhouse. It has developed a gluttonous appetite for coal, one of the most climate-changing fuels and the source of nearly two-thirds of the country’s power. India recently overtook Russia to become the world’s third-biggest greenhouse gas polluter, behind China and the United States. (If you count the European Union as a single carbon-belching bloc, then India comes in fourth).

India has been obstructing progress on international climate talks, culminating during the two weeks of U.N. Framework Convention on Climate Change negotiations that ended Saturday in Warsaw. The Warsaw talks were the latest annual get-together for nearly 200 countries trying to thrash out a new climate treaty to replace the Kyoto Protocol.

India’s erraticism at international climate talks is frustrating the West. But it is also starting to anger some developing nations struggling to cope with violent weather, droughts, and floods blamed on climate change.

India’s stance during climate talks is that developed countries should be legally committed to addressing global warming by reducing their greenhouse gas emissions, and that developing countries should do what they say they can do to help out.

But once-clear distinctions between developed and developing countries are blurring. A growing number of developing countries—including low-lying island states in the Pacific and some countries in Africa and Latin America with which India has long been allied—are eyeing the vast, growing, climate-changing pollution being pumped out by China and India. They are wondering why those two countries, and others in the “developing” camp, shouldn’t also be committed to reducing their emissions.

The Warsaw meetings ended with India and China thwarting efforts by the United States, Europe, and others to commit all countries to measures to address greenhouse gas pollution. Instead, countries agreed in Warsaw to announce their “intended contributions” to slow down global warming in 2015, in advance of final meetings planned in Paris to agree on the new climate treaty.

“Developing countries are a varied group at this stage, and there is a growing frustration about the inability to move forward from some of these countries,” said Jake Schmidt, international climate policy director for the Natural Resources Defense Council, who attended the Warsaw meetings. “Some of their anger is directed at the U.S. and Europe, but more and more of their anger is quietly being directed at friends in the developing world that they see as stalling progress.”

And no country has done more than India to stall progress on international climate negotiations during the past two months.

It began last month in Bangkok, when negotiators met to update the Montreal Protocol. Signed in the late 1980s, the protocol saved the ozone layer by ending the use of chlorofluorocarbons in refrigerants, household goods, and industrial products. The problem was, manufacturers often swapped out CFCs for a closely related group of chemicals called hydrofluorocarbons. HFCs don’t hurt the ozone layer, but it turns out that they are potent greenhouse gases. With climate change now the most important global environmental challenge, the United States and a long list of other countries have proposed amending the Montreal Protocol to phase out the use of HFCs.

All seemed to be going well with the plans for those amendments. India and the other members of the Group of 20 endorsed the proposal during September meetings in Russia. A couple of weeks later, Indian Prime Minister Manmohan Singh reiterated the country’s support for the amendments during meetings with President Obama.

But when international representatives gathered for meetings in Bangkok to actually make the amendments, they were surprised and angered to find the negotiations blocked by India. The country’s environment officials told Indian media that they were worried about the costs associated with switching over to new coolants. What may have worried them even more was the fear of being accused of opening the door for foreign air conditioning and fridge companies to take over domestic markets.

If there’s one thing that no Indian government up for re-election in the current political climate would want, it’s to be seen giving an inch to America on trade.

Then came Warsaw. Extensive negotiations around agriculture had been scheduled for the first of the two weeks of meetings. Farming causes about a fifth of greenhouse gas emissions, due in part to land clearing, energy use, and the methane that bubbles up from rice paddies and is belched out by cattle.

But that’s not what drew farming representatives to Warsaw. Farmers are the hardest hit by changes in the weather—which should help them secure a chunk of the hundreds of billions of dollars in climate aid that a new climate treaty is expected to deliver for poor countries. But India, which is home to farms that are struggling to cope with changing rainfall patterns, spearheaded a maneuver that blocked agricultural negotiations from moving forward. Its negotiators feared that negotiations over farmer adaptation efforts would lead to requests that those farmers also reduce their carbon footprints.

“India has been very clear that agriculture is the mainstay of our population, and we don’t want any mitigation targets there,” said Indrajit Bose, a climate change program manager at the influential Delhi-based Centre for Science and Environment, who attended the Warsaw meetings. “It’s a red line for India, and I think we agree with that.”

During the second week of Warsaw talks, India again blocked progress on HFC reductions, and it worked with China to water down the meeting’s most important agreement on the final day of talks.

Despite instances of Chinese obstructionism at Warsaw, China and the United States have been making headlines during the past week for their blossoming mutual commitment to tackling climate change. Now India appears to be supplanting China as the developing world’s chief climate agitator, even as it takes real steps to boost renewable energy production at home and meet voluntary goals to reduce the “emission intensity” of its economy. (Meanwhile, Japan, Australia, and Canada are taking America’s mantle as the developed world’s chief climate antagonists.)

The India problem isn’t limited to climate talks. Early this year India helped dilute an international agreement that had been crafted to reduce mercury pollution—a major problem with coal-fired power plants.

Before the country’s environment minister was replaced during a mid-2011 Cabinet reshuffle, India had been hailed as a constructive leader during international climate talks. Now it’s being accused of foot-dragging, obstructionism, and flip-flopping.

Recent Indian shenanigans on the global climate stage are partly a reflection of the fact that a federal election will be held in the spring. Such elections are held every five years, and frantic campaigning by long lists of parties occupies many of the months that precede them. In India, despite the country’s acute vulnerability to climate change, the climate is simply not an election issue. BBC polling suggests that 39 percent of Indians have never heard about “climate change.” Indian voters are calling for more affordable energy—not for a reduction in greenhouse gas emissions.

And India, like other developing countries, has been angered by what appears to be reluctance by developed countries to lend a meaningful financial hand as the climate goes awry. A cruel irony of climate change is that the poor countries that did the least to warm the planet are often the hardest hit, vulnerable to rising tides, crop-wilting droughts, and powerful storms. During the talks in Warsaw, Western countries were suddenly balking at previously promised climate aid that would have been worth $100 billion a year by 2020. And developed countries have fobbed off developing countries’ appeals for additional compensation, so-called loss-and-damage payments, when climate change has harmed their people and economies.

It’s not just the electioneering in India that’s causing problems for global climate talks. Another problem seems to be how little press attention the country receives on foreign shores. “There’s not a lot of focus on India anywhere,” said Manish Ram, a renewable-energy analyst for Greenpeace India who attended the Warsaw meetings. “That’s one of the reasons India gets away with doing what it’s been doing.”

Sobre a COP 19 de Varsóvia

JC e-mail 4864, de 28 de novembro de 2013

Resultados de conferência da ONU sobre o clima ficaram abaixo da expectativa, diz Capiberibe

Ele observou que as dificuldades encontradas durante a conferência terminaram por adiar por um dia o encerramento das negociações

O senador João Capiberibe (PSB-AP) comentou nesta quarta-feira (27) a realização da 19ª Conferência Mundial do Clima da Organização das Nações Unidas (ONU), encerrada no último sábado, em Varsóvia. Na avaliação de Capiberibe, os resultados da conferência ficaram abaixo da expectativa, principalmente porque foi mal recebida pelos países desenvolvidos a tese de responsabilidade histórica pelos danos ambientais.

Ele observou que as dificuldades encontradas durante a conferência terminaram por adiar por um dia o encerramento das negociações.

– A conferência, na verdade, deveria ter sido concluída na sexta-feira, e nós aguardamos até as 19h para o encerramento a apresentação do relatório final, que não foi possível em função das enormes contradições que envolvem esse tema. Os negociadores vararam a noite e só foi possível apresentar relatório final no sábado quando já estávamos de volta a nosso país – relatou Capiberibe.

O senador ainda afirmou que as mudanças no clima representam uma crise global que veio para ficar e exige decisões rápidas. Capiberibe destacou o compromisso do Brasil com o desenvolvimento sustentável e classificou o novo Código Florestal como um retrocesso que põe em risco o meio ambiente:

– E do ano passado para cá nós tivemos um aumento de 28% no processo de desmatamento, e isso pode estar ligado – nós não podemos afirmar – ao novo Código Ambiental, que terminou permitindo, anistiando desmatadores, anistiando aqueles que agridem a legislação, anistiando os que cometem crimes ambientais, e isso, evidentemente, estimula o desmatamento – afirmou.

Vanessa Grazziotin: conferência do clima surpreende e obtém avanço na proteção a florestas

O maior avanço alcançado foi o estabelecimento de regras para o pagamento aos países que protegerem suas áreas de florestas, o chamado REDD+

A senadora Vanessa Grazziotin (PCdoB-AM) registrou a participação dela e de outros senadores na 19ª Conferência do Clima da ONU, a COP 19, ocorrida em Varsóvia, na Polônia, na semana passada. Ela se disse surpresa com os resultados de uma reunião em torno da qual “não pairava qualquer expectativa”.

Segundo a parlamentar, o maior avanço alcançado foi o estabelecimento de regras para o pagamento aos países que protegerem suas áreas de florestas, o chamado REDD+. Para ter acesso aos recursos, os países devem reduzir emissões de carbono por desmatamento e degradação florestal.

– É uma mudança de lógica, de paradigma, dentro da própria política internacional sobre mudanças climáticas, já que até então o que tínhamos eram recursos para nações que recuperassem florestas degradadas. Isso é importante para o mundo inteiro, mas em particular para o nosso país, por que temos a maior floresta tropical do mundo e estamos em processo de desenvolvimento – explicou a parlamentar.

Vanessa Grazziotin observou, ainda, que o tema do pagamento pela proteção de florestas ganhou mais importância nas discussões da COP 19 que o do comércio de carbono, por meio do qual países podem pagar a outros pelo excesso de emissão de gases causadores do efeito estufa.

– Isso não ajuda o clima. Então esse debate ficou em plano secundário – assinalou Vanessa Grazziotin. Ela esclareceu que as regras aprovadas em Varsóvia preveem a utilização de dinheiro do Fundo Verde, aprovado em 2010 e que já tem recursos disponíveis a partir deste ano, embora a maior parte das verbas vá ser aportada em 2014.

Vanguarda
A parlamentar pelo Amazonas chamou a atenção para o papel relevante do Brasil no avanço da agenda ambiental. Sétimo no ranking da economia mundial, o país é “uma nação líder” no que se refere a proteção ao meio ambiente. Não só por causa da maior floresta tropical do mundo, mas também das posições importantes que assume nos fóruns internacionais, entre as quais as de fortalecimento do grupo dos 77 países em desenvolvimento e do Basic (Brasil, África do Sul, Índia e China).

O Brasil, observou ainda Vanessa Grazziotin, tem uma meta interna voluntária, em lei, “das maiores do mundo”: de 36% a quase 39% de redução das emissões brasileiras até o ano de 2020, levando-se em conta índices de 1995.

Tanto a Conferência das Partes, realizada na Polônia, como a próxima, que será realizada em Lima, no Peru, serão preparatórias para a 21ª Conferência das Partes, marcada para ocorrer em Paris. Na 21ª Conferência, será elaborada uma nova convenção, pela qual todos países terão regras estabelecidas internacionalmente para a redução de emissão de gases de efeito estufa.

Estiveram em Varsóvia, além de Vanessa Grazziotin, os senadores João Capiberibe (PSB-AP), Sérgio Souza (PMDB-PR) e Anibal Diniz (PT-AC). O grupo participou igualmente de uma reunião da Globe Internacional, entidade ambiental que reúne parlamentares de vários países.

ONGs abandonam conferência do clima (Folha de S.Paulo)

JC e-mail 4860, de 22 de novembro de 2013

É a primeira vez que as principais organizações ambientalistas deixam a reunião da ONU, realizada há 19 anos

Pela primeira vez nos 19 anos de realização das conferências mundiais do clima da ONU, as principais ONGs ambientalistas abandonaram o encontro, que deve acabar na noite de hoje em Varsóvia.

O maior objetivo da conferência é delinear um esboço para um acordo sobre redução de emissões de gases-estufa a ser fechado em 2015.

As ONGs, como Greenpeace, Oxfam e WWF, se dizem insatisfeitas com o ritmo das negociações e com países que voltaram atrás em compromissos ambientais.

Os articuladores estimam que 800 pessoas tenham abandonado a cúpula.

A ausência dos ambientalistas foi rapidamente percebida no Estádio Nacional de Varsóvia, onde acontecem as negociações. Além dos stands vazios, os corredores estavam em silêncio.

“Os governos deram um tapa na cara dos que sofrem com os perigosos impactos das mudanças climáticas”, disse KumiNaidoo, diretor-executivo do Greenpeace.

“Chegamos a um ponto tão difícil, com as coisas tão empacadas, que não havia outra solução. Não estamos abandonando o movimento, apenas essa conferência, que chegou a uma situação insustentável”, disse André Nahur, da WWF-Brasil.

A saída acontece após uma semana considerada de reveses pelos ambientalistas. O Japão anunciou que não vai cumprir suas metas de redução de emissões de gases-estufa e outros países ricos estão relutantes em destinar mais dinheiro à redução dos danos causados pela mudança climática. Na quarta-feira, o presidente da COP-19, MarcinKorolec, perdeu seu emprego como ministro do Meio Ambiente da Polônia.

Ele divulgou uma nota na qual lamenta a saída das ONGs. “Observadores não governamentais sempre mobilizaram os negociadores para maiores ambições.”

A decisão de abandonar as negociações não foi unanimidade. Após a saída do estádio, alguns manifestantes discretamente evitaram entregar seus crachás. “Quero voltar, o ato foi mais uma coisa simbólica”, disse uma ambientalista brasileira.

Enquanto ONGs e diplomatas mantiveram o tom pessimista ontem, o presidente da COP-19 enviou uma declaração à imprensa dizendo que as negociações avançaram.

“Após negociações que duraram a noite toda, atingimos um progresso considerável em financiamento climático. As conversas sobre a forma de um novo acordo global também entraram noite adentro. Estamos chegando perto do sucesso final.”

Something Is Rotten at the New York Times (Huff Post)

By Michael E. Mann

Director of Penn State Earth System Science Center; Author of ‘Dire Predictions’ and ‘The Hockey Stick and the Climate Wars’

Posted: 11/21/2013 7:20 pm

Something is rotten at the New York Times.

When it comes to the matter of human-caused climate change, the Grey Lady’s editorial page has skewed rather contrarian of late.

A couple months ago, the Intergovernmental Panel on Climate Change (IPCC) publishedits 5th scientific assessment, providing the strongest evidence to date that climate change is real, caused by us, and a problem.

Among other areas of the science where the evidence has become ever more compelling, is the so-called “Hockey Stick” curve — a graph my co-authors and I published a decade and a half ago showing modern warming in the Northern Hemisphere to be unprecedented for at least the past 1000 years. The IPCC further strengthened that original conclusion, finding that recent warmth is likely unprecedented over an even longer timeframe.

Here was USA Today on the development:

The latest report from the Intergovernmental Panel on Climate Change, the internationally accepted authority on the subject, concludes that the climate system has warmed dramatically since the 1950s, and that scientists are 95% to 100% sure human influence has been the dominant cause. In the Northern Hemisphere, 1983 to 2012 was likely the warmest 30-year period of the past 1,400 years, the IPCC found.

And here was the Washington Post:

The infamous “hockey stick” graph showing global temperatures rising over time, first slowly and then sharply, remains valid.

And the New York Times? Well we instead got this:

The [Hockey Stick] graph shows a long, relatively unwavering line of temperatures across the last millennium (the stick), followed by a sharp, upward turn of warming over the last century (the blade). The upward turn implied that greenhouse gases had become so dominant that future temperatures would rise well above their variability and closely track carbon dioxide levels in the atmosphere….I knew that wasn’t the case.

Huh?

Rather than objectively communicating the findings of the IPCC to their readers, the New York Times instead foisted upon them the ill-informed views of Koch Brothers-fundedclimate change contrarian Richard Muller, who used the opportunity to deny the report’s findings.

In fact, in the space of just a couple months now, the Times has chosen to grant Muller not just one, but two opportunities to mislead its readers about climate change and the threat it poses.

The Times has now published another op-ed by Muller wherein he misrepresented the potential linkages between climate change and extreme weather–tornadoes to be specific, which he asserted would be less of a threat in a warmer world. The truth is that the impact of global warming on tornadoes remains uncertain, because the underlying science is nuanced and there are competing factors that come into play.

The Huffington Post published an objective piece about the current state of the science earlier this year in the wake of the devastating and unprecedented Oklahoma tornadoes.

That piece accurately quoted a number of scientists including myself on the potential linkages. I pointed out to the journalist that there are two key factors: warm, moist air is favorable for tornadoes, and global warming will provide more of it. But important too is the amount of “shear” (that is, twisting) in the wind. And whether there will, in a warmer world, be more or less of that in tornado-prone regions, during the tornado season, depends on the precise shifts that will take place in the jet stream–something that is extremely difficult to predict even with state-of-the-art theoretical climate models. That factor is a “wild card” in the equation.

So we’ve got one factor that is a toss-up, and another one that appears favorable for tornado activity. The combination of them is therefore slightly on the “favorable” side, and if you’re a betting person, that’s probably what you would go with. And this is the point that I made in the Huffington Post piece:

Michael Mann, a climatologist who directs the Earth System Science Center at Pennsylvania State University, agreed that it’s too early to tell.

“If one factor is likely to be favorable and the other is a wild card, it’s still more likely that the product of the two factors will be favorable,” said Mann. “Thus, if you’re a betting person — or the insurance or reinsurance industry, for that matter — you’d probably go with a prediction of greater frequency and intensity of tornadoes as a result of human-caused climate change.”

Now watch the sleight of hand that Muller uses when he quotes me in his latest Times op-ed:

Michael E. Mann, a prominent climatologist, was only slightly more cautious. He said, “If you’re a betting person — or the insurance or reinsurance industry, for that matter — you’d probably go with a prediction of greater frequency and intensity of tornadoes as a result of human-caused climate change.”

Completely lost in Muller’s selective quotation is any nuance or context in what I had said, let alone the bottom line in what I stated: that it is in fact too early to tell whether global warming is influencing tornado activity, but we can discuss the processes through which climate change might influence future trends.

Muller, who lacks any training or expertise in atmospheric science, is more than happy to promote with great confidence the unsupportable claim that global warming will actuallydecrease tornado activity. His evidence for this? The false claim that the historical data demonstrate a decreasing trend in past decades.

Actual atmospheric scientists know that the historical observations are too sketchy and unreliable to decide one way or another as to whether tornadoes are increasing or not (see this excellent discussion by weather expert Jeff Masters of The Weather Underground).

So one is essentially left with the physical reasoning I outlined above. You would think that a physicist would know how to do some physical reasoning. And sadly, in Muller’s case, you would apparently be wrong…

To allow Muller to so thoroughly mislead their readers, not once, but twice in the space of as many months, is deeply irresponsible of the Times. So why might it be that the New York Times is so enamored with Muller, a retired physicist with no training in atmospheric or climate science, when it comes to the matter of climate change?

I discuss Muller’s history as a climate change critic and his new-found role as a media favorite in my book “The Hockey Stick and the Climate Wars” (the paperback was just released a couple weeks ago, with a new guest foreword by Bill Nye “The Science Guy”).

Muller is known for his bold and eccentric, but flawed and largely discredited astronomical theories. But he rose to public prominence only two years ago when he cast himself in theirresistible role of the “converted climate change skeptic”.

Muller had been funded by the notorious Koch Brothers, the largest current funders of climate change denial and disinformation, to independently “audit” the ostensibly dubious science of climate change. This audit took the form of an independent team of scientists that Muller picked and assembled under the umbrella of the “Berkeley Earth Surface Temperature” (unashamedly termed “BEST” by Muller) project.

Soon enough, Muller began to unveil the project’s findings: First, in late 2011, he admitted that the Earth was indeed warming. Then, a year later he concluded that the warming was not only real, but could only be explained by human influence.

Muller, in short, had rediscovered what the climate science community already knew long ago.

summarized the development at the time on my Facebook page:

Muller’s announcement last year that the Earth is indeed warming brought him up to date w/ where the scientific community was in the the 1980s. His announcement this week that the warming can only be explained by human influences, brings him up to date with where the science was in the mid 1990s. At this rate, Muller should be caught up to the current state of climate science within a matter of a few years!

The narrative of a repentant Koch Brothers-funded skeptic who had “seen the light” andappeared to now endorse the mainstream view of human-caused climate change, was simply too difficult for the mainstream media to resist. Muller predictably was able to position himself as a putative “honest broker” in the climate change debate. And he was granted a slew of op-eds in the New York Times and Wall Street Journal, headline articles in leading newspapers, and interviews on many of the leading television and radio news shows.

Yet Muller was in reality seeking to simply take credit for findings established by otherscientists (ironically using far more rigorous and defensible methods!) literally decades ago. In 1995 the IPCC had already concluded, based on work by Ben Santer and other leading climate scientists working on the problem of climate change “detection and attribution”, that there was already now a “discernible human influence” on the warming of the planet.

And while Muller has now admitted that the Earth had warmed and that human-activity is largely to blame, he has used his new-found limelight and access to the media to:

1. Smear and misrepresent other scientists, including not just me and various other climate scientists like Phil Jones of the UK’s University of East Anglia, but even the President of the U.S. National Academy of Sciences himself, Ralph Cicerone.

2. Misrepresent key details of climate science, inevitably to downplay the seriousness of climate change, whether it is the impacts on extreme weather and heat, drought, Arctic melting, or the threat to Polar Bears. See my own debunking of various falsehoods that Muller has promoted in his numerous news interviews e.g. here or here.

3. Shill for fossil fuel energy, arguing that the true solution to global warming isn’t renewable or clean energy. No, not at all! Muller is bullish on fracking and natural gas as the true solution.

To (a) pretend to accept the science, but attack the scientists and misrepresent so many important aspect of the science, downplaying the impacts and threat of climate change, while (b) acting as a spokesman for natural gas, one imagines that the petrochemical tycoon Koch Brothers indeed were probably quite pleased with their investment. Job well done. As I put it in an interview last year:

It would seem that Richard Muller has served as a useful foil for the Koch Brothers, allowing them to claim they have funded a real scientist looking into the basic science, while that scientist– Muller—props himself up by using the “Berkeley” imprimatur (UC Berkeley has not in any way sanctioned this effort) and appearing to accept the basic science, and goes out on the talk circuit, writing op-eds, etc. systematically downplaying the actual state of the science, dismissing key climate change impacts and denying the degree of risk that climate change actually represents. I would suspect that the Koch Brothers are quite happy with Muller right now, and I would have been very surprised had he stepped even lightly on their toes during his various interviews, which he of course has not. He has instead heaped great praise on them, as in this latest interview.

The New York Times does a disservice to its readers when it buys into the contrived narrative of the “honest broker”–Muller as the self-styled white knight who must ride in to rescue scientific truth from a corrupt and misguided community of scientists. Especially when that white knight is in fact sitting atop a Trojan Horse–a vehicle for the delivery of disinformation, denial, and systematic downplaying of what might very well be the greatest threat we have yet faced as a civilization, the threat of human-caused climate change.

Shame on you New York Times. You owe us better than this.

Majority of red-state Americans believe climate change is real, study shows (The Guardian)

Study suggests far-reaching acceptance of climate change in traditionally Republican states such as Texas and Oklahoma

A vast majority of red-state Americans believe climate change is real and at least two-thirds of those want the government to cut greenhouse gas emissions, new research revealed on Wednesday.

The research, by Stanford University social psychologist Jon Krosnick, confounds the conventional wisdom of climate denial as a central pillar of Republican politics, and practically an article of faith for Tea Party conservatives.

Instead, the findings suggest far-reaching acceptance that climate change is indeed occurring and is caused by human activities, even in such reliably red states as Texas and Oklahoma.

“To me, the most striking finding that is new today was that we could not find a single state in the country where climate scepticism was in the majority,” Krosnick said in an interview.

States that voted for Barack Obama, as expected, also believe climate change is occurring and support curbs on carbon pollution. Some 88% of Massachusetts residents believe climate change is real.

But Texas and Oklahoma are among the reddest of red states and are represented in Congress by Republicans who regularly dismiss the existence of climate change or its attendant risks.

Congressman Joe Barton of Texas and Senator Jim Inhofe of Oklahoma stand out for their regular denials of climate change as a “hoax”, even among Republican ranks.

However, the research found 87% of Oklahomans and 84% of Texans accepted that climate change was occurring.

Seventy-six percent of Americans in both states also believed the government should step in to limit greenhouse gas emissions produced by industry.

In addition, the research indicated substantial support for Obama’s decision to use the Environmental Protection Agency to cut emissions from power plants. The polling found at least 62% of Americans in favour of action cutting greenhouse gas emissions from plants.

Once again, Texas was also solidly lined up with action, with 79% of voters supporting regulation of power plants.

The acceptance of climate change was not a result of outreach efforts by scientists, however, or by the experience of extreme events, such as hurricane Sandy, Krosnick said.

His research found no connection between Sandy and belief in climate change or support for climate action.

Instead, he said the findings suggest personal experiences of hot weather – especially in warm states in the south-west – persuaded Texans and others that the climate was indeed changing within their own lifetimes.

“Their experience with weather leaves people in most places on the green side in most of the questions we ask,” he said.

There was some small slippage in acceptance of climate change in north-western states such as Idaho and Utah and in the industrial heartland states of Ohio. But even then at a minimum, 75% believed climate change was occurring.

The findings, represented in a series of maps, were presented at a meeting of the bicameral task force on climate change which has been pushing Congress to try to move ahead on Obama’s green commitments. There was insufficient data to provide findings from a small number of states

Henry Waxman, the Democrat who co-chairs the taskforce, said in a statement the findings showed Americans were ready to take action to cut emissions that cause climate change.

“This new report is crystal clear,” said Waxman. “It shows that the vast majority of Americans – whether from red states or blue – understand that climate change is a growing danger. Americans recognise that we have a moral obligation to protect the environment and an economic opportunity to develop the clean energy technologies of the future. Americans are way ahead of Congress in listening to the scientists.”

Some 58% of Republicans in the current Congress deny the existence of climate change or oppose action to cut greenhouse gas emissions, according to an analysis by the Center for American Progress.

Just 90 companies caused two-thirds of man-made global warming emissions (The Guardian)

Chevron, Exxon and BP among companies most responsible for climate change since dawn of industrial age, figures show

The climate crisis of the 21st century has been caused largely by just 90 companies, which between them produced nearly two-thirds of the greenhouse gas emissions generated since the dawning of the industrial age, new research suggests.The companies range from investor-owned firms – household names such as Chevron, Exxon and BP – to state-owned and government-run firms.The analysis, which was welcomed by the former vice-president Al Goreas a “crucial step forward” found that the vast majority of the firms were in the business of producing oil, gas or coal, found the analysis, which has been accepted for publication in the journal Climatic Change.”There are thousands of oil, gas and coal producers in the world,” climate researcher and author Richard Heede at the Climate Accountability Institute in Colorado said. “But the decision makers, the CEOs, or the ministers of coal and oil if you narrow it down to just one person, they could all fit on a Greyhound bus or two.”Half of the estimated emissions were produced just in the past 25 years – well past the date when governments and corporations became aware that rising greenhouse gas emissions from the burning of coal and oil were causing dangerous climate change.Many of the same companies are also sitting on substantial reserves of fossil fuel which – if they are burned – puts the world at even greater risk of dangerous climate change.Climate change experts said the data set was the most ambitious effort so far to hold individual carbon producers, rather than governments, to account.The United Nations climate change panel, the IPCC, warned in September that at current rates the world stood within 30 years of exhausting its “carbon budget” – the amount of carbon dioxide it could emit without going into the danger zone above 2C warming. The former US vice-president and environmental champion, Al Gore, said the new carbon accounting could re-set the debate about allocating blame for the climate crisis.Leaders meeting in Warsaw for the UN climate talks this week clashed repeatedly over which countries bore the burden for solving the climate crisis – historic emitters such as America or Europe or the rising economies of India and China.Gore in his comments said the analysis underlined that it should not fall to governments alone to act on climate change.”This study is a crucial step forward in our understanding of the evolution of the climate crisis. The public and private sectors alike must do what is necessary to stop global warming,” Gore told the Guardian. “Those who are historically responsible for polluting our atmosphere have a clear obligation to be part of the solution.”Between them, the 90 companies on the list of top emitters produced 63% of the cumulative global emissions of industrial carbon dioxide and methane between 1751 to 2010, amounting to about 914 gigatonne CO2 emissions, according to the research. All but seven of the 90 wereenergy companies producing oil, gas and coal. The remaining seven were cement manufacturers.The list of 90 companies included 50 investor-owned firms – mainly oil companies with widely recognised names such as Chevron, Exxon, BP , and Royal Dutch Shell and coal producers such as British Coal Corp, Peabody Energy and BHP Billiton.Some 31 of the companies that made the list were state-owned companies such as Saudi Arabia’s Saudi Aramco, Russia’s Gazprom and Norway’s Statoil.Nine were government run industries, producing mainly coal in countries such as China, the former Soviet Union, North Korea and Poland, the host of this week’s talks.Experts familiar with Heede’s research and the politics of climate change said they hoped the analysis could help break the deadlock in international climate talks.”It seemed like maybe this could break the logjam,” said Naomi Oreskes, professor of the history of science at Harvard. “There are all kinds of countries that have produced a tremendous amount of historical emissions that we do not normally talk about. We do not normally talk about Mexico or Poland or Venezuela. So then it’s not just rich v poor, it is also producers v consumers, and resource rich v resource poor.”Michael Mann, the climate scientist, said he hoped the list would bring greater scrutiny to oil and coal companies’ deployment of their remaining reserves. “What I think could be a game changer here is the potential for clearly fingerprinting the sources of those future emissions,” he said. “It increases the accountability for fossil fuel burning. You can’t burn fossil fuels without the rest of the world knowing about it.”Others were less optimistic that a more comprehensive accounting of the sources of greenhouse gas emissions would make it easier to achieve the emissions reductions needed to avoid catastrophic climate change.John Ashton, who served as UK’s chief climate change negotiator for six years, suggested that the findings reaffirmed the central role of fossil fuel producing entities in the economy.”The challenge we face is to move in the space of not much more than a generation from a carbon-intensive energy system to a carbonneutral energy system. If we don’t do that we stand no chance of keeping climate change within the 2C threshold,” Ashton said.”By highlighting the way in which a relatively small number of large companies are at the heart of the current carbon-intensive growth model, this report highlights that fundamental challenge.”Meanwhile, Oreskes, who has written extensively about corporate-funded climate denial, noted that several of the top companies on the list had funded the climate denial movement.”For me one of the most interesting things to think about was the overlap of large scale producers and the funding of disinformation campaigns, and how that has delayed action,” she said.The data represents eight years of exhaustive research into carbon emissions over time, as well as the ownership history of the major emitters.The companies’ operations spanned the globe, with company headquarters in 43 different countries. “These entities extract resources from every oil, natural gas and coal province in the world, and process the fuels into marketable products that are sold to consumers on every nation on Earth,” Heede writes in the paper.The largest of the investor-owned companies were responsible for an outsized share of emissions. Nearly 30% of emissions were produced just by the top 20 companies, the research found.By Heede’s calculation, government-run oil and coal companies in the former Soviet Union produced more greenhouse gas emissions than any other entity – just under 8.9% of the total produced over time. China came a close second with its government-run entities accounting for 8.6% of total global emissions.ChevronTexaco was the leading emitter among investor-owned companies, causing 3.5% of greenhouse gas emissions to date, with Exxon not far behind at 3.2%. In third place, BP caused 2.5% of global emissions to date.The historic emissions record was constructed using public records and data from the US department of energy’s Carbon Dioxide Information and Analysis Centre, and took account of emissions all along the supply chain.The centre put global industrial emissions since 1751 at 1,450 gigatonnes.

Um balanço da primeira semana da COP19 (Vitae Civilis)

cop19 ecod 300x183 Um balanço da primeira semana da COP19

Ao fim da primeira semana da CoP19, a sensação de dejá vú é inevitável. Mais uma vez, o negociador filipino foi o responsável pelo discurso mais emocionante. Mais uma vez, o Germanwatch divulga que os países pobres são os mais vulneráveis aos eventos climáticos extremos. Mais uma vez, aliás, temos um evento climático vitimando milhares de pessoas enquanto acontece a conferência. Mais uma vez, temos a divulgação de que estamos vivendo os anos mais quentes da história recente do planeta, de que a quantidade de gases causadores do efeito estufa na atmosfera já está em níveis alarmantes, de que o certo seria deixar as reservas de combustíveis fósseis intocadas…

Mesmo o novo relatório do IPCC chega com um certo gosto de notícia velha. Pois apesar da maior gama de detalhes e da maior certeza científica, basicamente o AR5 confirma que estamos seguindo em uma trajetória que esgotará já em 2030 todo o carbono que poderemos queimar neste século sem alterar perigosamente o clima do planeta. Da mesma forma, a Agência Internacional de Energia (IEA) confirma o exposto por uma forte campanha feita na CoP18 contra os subsídios aos combustíveis fósseis. Segundo a IEA, os governos gastaram US$ 523 bilhões em subsídios aos combustíveis fósseis em 2011 – uma completa inversão de prioridades, do ponto de vista da mudança climática: para cada US$ 1 em apoio às energias renováveis​​, outros US$ 6 estão promovendo combustíveis intensivos em carbono. Parte dos subsídios aos combustíveis fósseis estão acontecendo em países emergentes e em desenvolvimento, haja vista os subsídios à gasolina impostos pelo governo brasileiro à Petrobrás. Mas talvez sejam mais importantes nos países ricos. Pesquisa do Overseas Development Institute, do Reino Unido, mostrou que os subsídios ao consumo de combustíveis fósseis em 11 países da OCDE alcançam o total de US$ 72 bilhões dólares, ou cerca de US$ 112 por habitante adulto destes países.

Essa perversidade econômica estrangula, no nascimento, as inovações tecnológicas que podem contribuir para evitarmos a colisão iminente entre a economia global (e o seu sistema energético) e os limites ecológicos do nosso planeta. Os recentes desenvolvimentos em energia eólica, solar, bio-combustíveis , geotermia, marés, células de combustível e eficiência energética estão aumentando as possibilidades de construção de um cenário energético de baixo carbono. Além de poderem afastar a crise climática, estas tecnologias poderiam abrir novas oportunidades de investimento, fornecer energia a preços acessíveis e sustentar o crescimento. Mas este potencial somente será realizado se os governos perseguirem ativamente políticas industriais sustentáveis. É necessário alinhar o objetivo de mitigação da crise climática com desincentivos para as fontes de energia intensivas em carbono por meio de impostos e apoio a alternativas sustentáveis.

O fim dos subsídios aos combustíveis fósseis precisa ser acompanhado por políticas que favoreçam a transferência de tecnologias limpas. Não podemos deixar de lado o exemplo da China, da Índia e também do Brasil, para onde multinacionais historicamente enviam plataformas de produção sujas e energo-intensivas. Infelizmente, as negociações sobre tecnologia estão entre as mais emperradas – tanto no formato anterior, estabelecido pelo Caminho de Bali, como agora, na chamada Plataforma Durban. Simultaneamente, tomamos conhecimento, pelo WikiLeaks, da Parceria Trans-Pacífica (TPP) referente a patentes e proteção intelectual – acordo que vem sendo negociado secretamente entre líderes de 12 países que concentram 40% do PIB e um terço do comércio global e que visa impor medidas mais agressivas para coibir a quebra de propriedade intelectual.

A discrepância entre o que a ciência recomenda e o que os governos estão promovendo permanece, independente do formato das negociações climáticas. Saímos dos dois trilhos estabelecidos em Bali para a Plataforma Durban, mas os compromissos financeiros ou metas mais agressivas de mitigação não vieram. Na primeira semana da CoP19, os discursos dos negociadores reviveram posicionamentos arcaicos e obstrutivos ao processo. Sim, é certo que já sabíamos que esta não seria uma conferência de grandes resultados. Mas o fato é que os bad guys resolveram ser realmente bad sob a condução complacente de uma presidência que não se constrange em explicitar sua conduta em prol do carvão e demais combustíveis fósseis. Tanto que a Rússia abriu mão de atravancar o processo, guardando suas queixas sobre o processo da UNFCCC para outra ocasião.

Esta outra ocasião pode ser a CoP20, no Peru, para onde as esperanças de negociações mais produtivas se voltam. Antes, porém, haverá a cúpula de Ban Ki Moon, para a qual as lideranças dos países estão convidadas. O objetivo é gerar a sensibilidade política que faltou em Copenhague e tentar definir metas antes da reta derradeira do acordo, em Paris. Esse encontro deve ser precedido e seguido de várias reuniões interseccionais para que os delegados avancem na costura do acordo e para que os itens críticos, como metas de mitigação e financiamento, comecem a adquirir contornos mais concretos.

Em outras palavras, uma agenda consistente de reuniões e o compromisso para apresentar metas no ano que vem são o melhor resultado que podemos esperar de uma conferência que corre o risco de entrar para a História como a CoP do carvão.

Climate change pledges: rich nations face fury over moves to renege (The Guardian)

Typhoon Haiyan raises fear over global warming threat as Philippines leads attack on eve of key talks

 in Warsaw

The Observer, Sunday 17 November 2013

Developing nations have launched an impassioned attack on the failure of the world’s richest countries to live up to their climate change pledges in the wake of the disaster in the Philippines.

With more than 3,600 people now believed to have been killed byTyphoon Haiyan, moves by several major economies to backtrack on commitments over carbon emissions have put the world’s poorest and most wealthy states on a collision course, on the eve of crucial high-level talks at a summit of world powers.

Yeb Sano, the Philippines’ lead negotiator at the UN climate change summit being held this weekend in Warsaw, spoke of a major breakdown in relations overshadowing the crucial talks, which are due to pave the way for a 2015 deal to bring down global emissions.

The diplomat, on the sixth day of a hunger strike in solidarity for those affected by Haiyan, including his own family, told the Observer: “We are very concerned. Public announcements from some countries about lowering targets are not conducive to building trust. We must acknowledge the new climate reality and put forward a new system to help us manage the risks and deal with the losses to which we cannot adjust.”

Munjurul Hannan Khan, representing the world’s 47 least affluent countries, said: “They are behaving irrationally and unacceptably. The way they are talking to the most vulnerable countries is not acceptable. Today the poor are suffering from climate change. But tomorrow the rich countries will be. It starts with us but it goes to them.”

Recent decisions by the governments of AustraliaJapan and Canada to downgrade their efforts over climate change have caused panic among those states most affected by global warming, who fear others will follow as they rearrange their priorities during the downturn.

In the last few days, Japan has announced it will backtrack on its pledge to reduce its emission cuts from 25% to 3.8% by 2020 on the basis that it had to close its nuclear reactors after the 2011 earthquake and tsunami.

Australia, which is not sending a minister to this weekend’s talks,signalled it may weaken its targets and is repealing domestic carbon lawsfollowing the election of a conservative government.

Canada has pulled out of the Kyoto accord, which committed major industrial economies to reducing their annual CO2 emissions to below 1990 levels.

China’s lead negotiator at the Warsaw talks, Su Wei, said: “I do not have any words to describe my dismay at Japan’s decision.” He criticised Europe for showing a lack of ambition to cut emissions further, adding: “They talk about ratcheting up ambition, but rather they would have to ratchet up to ambition from zero ambition.”

When the highest-level talks start at the summit on Monday, due to be attended by representatives from 195 countries, including energy secretary Ed Davey, the developing world will seek confirmation from states such as Britain that they will not follow the path of Japan and others. David Cameron’s comments this weekend in which he backed carbon emission cuts and suggested that there was growing evidence of a link between manmade climate change and disasters such as Typhoon Haiyan, will inevitably be used to pressure others to offer similar assurances.

The developing world also wants the rich western nations to commit to establishing a compensation scheme for future extreme weather events, as the impact of global warming is increasingly felt. And they want firm signals that rich countries intend to find at least $100bn a year by 2020 to help them to adapt their countries to severe climate extremes.

China and 132 nations that are part of the G77 block of developing countries have expressed dismay that rich countries had refused to discuss a proposal for scientists to calculate emissions since the start of the Industrial Revolution.

Ambassador Jose Antonio Marcondes de Carvalho of Brazil, who initially proposed the talks, said: “We were shocked, very much surprised by their rejection and dismissal. It is puzzling. We need to understand why they have rejected it.

“Developing countries are doing vastly more to reduce their emissions than Annexe 1 [rich] countries.”

Members of the Disaster Emergencies Committee, which co-ordinates British aid efforts, also warned leaders that the disaster offers a glimpse of the future if urgent action is not taken.

Aid agencies including Christian Aid, Cafod, Care International, Oxfam and Tearfund said ministers meeting in the Polish capital must act urgently because climate change is likely to make such extreme weather events more common in the future, putting millions more lives at risk.

A Climate-Change Victory (Slate)

If global warming is slowing, thank the Montreal Protocol.

Climate deniers like to point to the so-called global warming “hiatus” as evidence that humans aren’t changing the climate. But according a new study, exactly the opposite is true: The recent slowdown in global temperature increases is partially the result of one of the few successful international crackdowns on greenhouse gases.

Back in 1988, more than 40 countries, including the United States, signed the Montreal Protocol, an agreement to phase out the use of ozone-depleting gases like chlorofluorocarbons. (Today the protocol has nearly 200 signatories.) According to the Environmental Protection Agency, CFC emissions are down 90 percent since the protocol, a drop that the agency calls “one of the largest reductions to date in global greenhouse gas emissions.” That’s a blessing for the ozone layer, but also for the climate. CFCs are a potent heat-trapping gas, and a new analysis published in Nature Geoscience finds that slashing them has been a major driver of the much-discussed slowdown in global warming.

Without the protocol, environmental economist Francisco Estrada of the Universidad Nacional Autónoma de México reports, global temperatures today would be about a tenth of a degree Celsius higher than they are. That’s roughly an eighth of the total warming documented since 1880.

Estrada and his co-authors compared global temperature and greenhouse gas emissions records over the last century and found that breaks in the steady upward march of both coincided closely. At times when emissions leveled off or dropped, such as during the Great Depression, the trend was mirrored in temperatures; likewise for when emissions climbed.

“With these breaks, what’s interesting is that when they’re common that’s pretty indicative of causation,” said Pierre Perron, a Boston University economist who developed the custom-built statistical tests used in the study.

The findings put a new spin on investigation into the cause of the recent “hiatus.” Scientists have suggested that several temporary natural phenomena, including thedeep ocean sucking up more heat, are responsible for this slowdown. Estrada says his findings show that a recent reduction in heat-trapping CFCs as a result of the Montreal Protocol has also played an important role.

“Paradoxically, the recent decrease in warming, presented by global warming skeptics as proof that humankind cannot affect the climate system, is shown to have a direct human origin,” Estrada writes in the study.

The chart below, from a column accompanying the study, illustrates that impact. The solid blue line shows the amount of warming relative to pre-industrial levels attributed to CFCs and other gases regulated by the Montreal Protocol; the dashed blue line is an extrapolation of what the level would be without the agreement. Green represents warming from methane; Estrada suggests that leveling out may be the result of improved farming practices in Asia. The diamonds are annual global temperature averages, with the red line fitted to them. The dashed red line represents Estrada’s projection of where global temperature would be without these recent mitigation efforts.

Estrada said his study doesn’t undermine the commonly accepted view among climate scientists that the global warming effect of greenhouse gases can take years or decades to fully manifest. Even if we cut off all emissions today, we’d still very likely see warming into the future, thanks to the long shelf life of carbon dioxide, the principal climate-change culprit. The study doesn’t let CO2 off the hook: The reduction in warming would likely have been even greater if CO2 had leveled off as much as CFCs and methane. Instead, Estrada said, it has increased 20 percent since the protocol was signed.

Still, the study makes clear that efforts to reduce greenhouse gas emissions—like arecent international plan to phase out hydrofluorocarbons, a group of cousin chemicals to CFCs that are used in air conditioners and refrigerators, and the Obama administration’s move this year to impose strict new limits on emissions from power plants—can have a big payoff.

“The Montreal Protocol was really successful,” Estrada said. And as policymakers and climate scientists gather in Warsaw, Poland, for the latest U.N. climate summit next week, “this shows that international agreements can really work.”

Condições meteorológicas extremas mataram 530 mil e causaram prejuízos de US$ 2,5 trilhões nos últimos 20 anos

Nos últimos 20 anos as condições meteorológicas extremas mataram 530 mil pessoas no mundo, causando prejuízos econômicos que chegam a US$ 2,5 trilhões, de acordo com o Germanwatch, instituição financiada pelo governo alemão. Este ano, somente o supertufão Haiyan, a 24ª tempestade tropical que assolou as Filipinas em 2013, pode ter matado 10 mil pessoas, embora o presidente Benigno Aquino agora negue a informação. Apesar dos números crescentes de fenômenos naturais extremos, muitos especialistas ainda temem traçar uma ligação direta com as mudanças no clima. A pergunta que muitos se fazem é até quando essa negativa vai continuar emperrando uma negociação mais contundente sobre as reduções das emissões de Gases de Efeito Estufa (GEE), ainda apontados como principal motivo das alterações climáticas.

Em 2012, os países mais afetados por desastres naturais foram o Paquistão, o Haiti e justamente as Filipinas, divulgou ontem a Organização das Nações Unidas.

– A tragédia humana causada pelo desdobramento do Haiyan só será capturada em relatórios futuros – afirmou Soenke Kreft, coautor do documento divulgado nos bastidores da 19ª Conferência do Clima (COP-19), que acontece desde a última segunda-feira na Polônia.

Durante a abertura do evento, o delegado filipino Naderev Sano anunciou greve de fome até o final da conferência, e ontem foi seguido por 30 ativistas num ato tido como o mais importante do segundo dia de debates.

– Vamos fazer um jejum em solidariedade à delegação filipina, com as vítimas do tufão, e até que se concretizem ações políticas reais nesta COP-19 – disse Angeli Apparedi, coordenadora da iniciativa que uniu ONGs de todo o mundo para a causa filipina.

Sano lembrou a urgência de medidas concretas contra o aquecimento global para evitar tragédias como a do Haiyan e pediu para que os países desenvolvidos reduzissem as emissões e aumentassem seu comprometimento com o Fundo Verde do Clima, que deveria repassar US$ 100 bilhões aos países em desenvolvimento para a mitigação das emissões e adaptações aos impactos das mudanças climáticas em 2020. Até 30 de julho deste ano, o fundo, que foi criado em 2010, tinha apenas US$ 9 milhões.

Os desastres e o clima
Apesar do receio do mundo científico em afirmar que essas tragédias estão ligadas às mudanças climáticas, alguns efeitos causados pelo aumento das temperaturas do planeta já são apontados como a principal causa da maior intensidade dos ciclones tropicais.

– Uma coisa é bastante concreta – afirmou Will Steffen, diretor-executivo do “Australian National Climate Change Institute” à Reuters. – A mudança climática está causando o aquecimento das águas da superfície, o que, por sua vez, aumenta a energia deste tipo de tempestade.

Ontem, a Organização Meteorológica Mundial (OMM) divulgou que a média mundial de temperatura entre janeiro e setembro deste ano foi meio ponto superior à registrada entre 1961 e 1990, o que faz de 2013 o ano mais quente da História. Além do aquecimento das águas, o aumento do nível do mar também é outro potencializador do tufões, dizem os especialistas. O relatório da OMM apontou que o nível dos mares e oceanos aumenta em média 3,2 milímetros por ano desde 1993.

– Não podemos afirmar que um fenômeno específico está ligado ou não às mudanças climáticas, pois eles naturalmente sempre aconteceram – diz André Ferretti, coordenador de estratégias de conservação da Fundação Grupo Boticário e também do Observatório do Clima, que acompanha as negociações na Polônia. – Mas já é possível dizer que eles estão mais fortes e frequentes por causa das alterações do clima. Infelizmente isso não deve pressionar os governos para um acordo na COP-19.

Resistência a metas globais atrasam acordo
Um encontro que nasce errado, parte de um raciocínio antigo e é encerrado sem conclusões. Este quadro se encaixa em todos os painéis dedicados ao debate sobre as mudanças climáticas realizados nos últimos anos. Para especialistas, a fórmula pode se repetir nesta Convenção do Clima (COP-19).

Os países em desenvolvimento chegaram à Polônia insistindo em uma tese nascida há mais de 15 anos: “Responsabilidades Comuns, Porém Diferenciadas” no combate às mudanças climáticas. Segundo ela, só nações desenvolvidas devem submeter-se a metas para redução das emissões de CO2.

– É um raciocínio muito simplório – ataca Bernardo Baeta Neves Strassburg, diretor-executivo do Instituto Internacional para Sustentabilidade (IIS) e professor do Departamento de Geografia e Meio Ambiente da PUC-Rio. – Desde que este argumento passou a ser usado, Brasil, Índia e China tornaram-se potências mundiais e, por isso, deveriam ter metas obrigatórias para diminuir suas emissões.

Brasil em posição ambígua
Entre os países emergentes, o Brasil seria o mais disposto a aceitar um acordo que limite a emissão de CO2, mas o governo estaria esperando a decisão da China, maior emissora mundial de gases-estufa, que negocia metas mais modestas.

Para Osvaldo Stella, diretor do Programa de Mudanças Climáticas do Instituto de Pesquisa Ambiental da Amazônia (Ipam), o Brasil perdeu força nas conferências internacionais.

– Temos uma posição ambígua – critica. – Estamos entre as maiores economias do mundo, mas nossos problemas estruturais são idênticos aos dos países pobres. Essa contradição dificulta nossa habilidade em negociar.

Strassburg e Stella criticam o modelo do painel da COP, em que as decisões devem ser aceitas por unanimidade.

– É claro que o debate precisa ser democrático, mas questões tão importantes para a Humanidade não podem esbarrar no bloqueio de um determinado tema – ressalta Stella.

Ambos concordam que esta conferência, assim como a COP-20 – que será realizada no ano que vem, no Peru – são fundamentais para que, em 2015, os governantes enfim assinem um acordo que limite as emissões de CO2.

No início da semana, o Painel Intergovernamental de Mudanças Climáticas (IPCC) divulgou algumas adaptações em seu último relatório, concluído em setembro. As mudanças, segundo os cientistas, não são significativas, e foram descobertas após a revisão do documento.

Geoengineering the Climate Could Reduce Vital Rains (Science Daily)

Oct. 31, 2013 — Although a significant build-up in greenhouse gases in the atmosphere would alter worldwide precipitation patterns, a widely discussed technological approach to reduce future global warming would also interfere with rainfall and snowfall, new research shows.

The international study, led by scientists at the National Center for Atmospheric Research (NCAR), finds that global warming caused by a massive increase in greenhouse gases would spur a nearly 7 percent average increase in precipitation compared to preindustrial conditions.

But trying to resolve the problem through “geoengineering” could result in monsoonal rains in North America, East Asia, and other regions dropping by 5-7 percent compared to preindustrial conditions. Globally, average precipitation could decrease by about 4.5 percent.

“Geoengineering the planet doesn’t cure the problem,” says NCAR scientist Simone Tilmes, lead author of the new study. “Even if one of these techniques could keep global temperatures approximately balanced, precipitation would not return to preindustrial conditions.”

As concerns have mounted about climate change, scientists have studied geoengineering approaches to reduce future warming. Some of these would capture carbon dioxide before it enters the atmosphere. Others would attempt to essentially shade the atmosphere by injecting sulfate particles into the stratosphere or launching mirrors into orbit with the goal of reducing global surface temperatures.

The new study focuses on the second set of approaches, those that would shade the planet. The authors warn, however, that Earth’s climate would not return to its preindustrial state even if the warming itself were successfully mitigated.

“It’s very much a pick-your-poison type of problem,” says NCAR scientist John Fasullo, a co-author. “If you don’t like warming, you can reduce the amount of sunlight reaching the surface and cool the climate. But if you do that, large reductions in rainfall are unavoidable. There’s no win-win option here.”

The study appears in an online issue of the Journal of Geophysical Research: Atmospheres, published this week by the American Geophysical Union. An international team of scientists from NCAR and 14 other organizations wrote the study, which was funded in part by the National Science Foundation (NSF), NCAR’s sponsor. The team used, among other tools, the NCAR-based Community Earth System Model, which is funded by NSF and the Department of Energy.

Future carbon dioxide, with or without geoengineering

The research team turned to 12 of the world’s leading climate models to simulate global precipitation patterns if the atmospheric level of carbon dioxide, a leading greenhouse gas, reached four times the level of the preindustrial era. They then simulated the effect of reduced incoming solar radiation on the global precipitation patterns.

The scientists chose the artificial scenario of a quadrupling of carbon dioxide levels, which is on the high side of projections for the end of this century, in order to clearly draw out the potential impacts of geoengineering.

In line with other research, they found that an increase in carbon dioxide levels would significantly increase global average precipitation, although there would likely be significant regional variations and even prolonged droughts in some areas.

Much of the reason for the increased rainfall and snowfall has to do with greater evaporation, which would pump more moisture into the atmosphere as a result of more heat being trapped near the surface.

The team then took the research one step further, examining what would happen if a geoengineering approach partially reflected incoming solar radiation high in the atmosphere.

The researchers found that precipitation amounts and frequency, especially for heavy rain events, would decrease significantly. The effects were greater over land than over the ocean, and particularly pronounced during months of heavy, monsoonal rains. Monsoonal rains in the model simulations dropped by an average of 7 percent in North America, 6 percent in East Asia and South America, and 5 percent in South Africa. In India, however, the decrease was just 2 percent. Heavy precipitation further dropped in Western Europe and North America in summer.

A drier atmosphere

The researchers found two primary reasons for the reduced precipitation.

One reason has to do with evaporation. As Earth is shaded and less solar heat reaches the surface, less water vapor is pumped into the atmosphere through evaporation.

The other reason has to do with plants. With more carbon dioxide in the atmosphere, plants partially close their stomata, the openings that allow them to take in carbon dioxide while releasing oxygen and water into the atmosphere. Partially shut stomata release less water, so the cooled atmosphere would also become even drier over land.

Tilmes stresses that the authors did not address such questions as how certain crops would respond to a combination of higher carbon dioxide and reduced rainfall.

“More research could show both the positive and negative consequences for society of such changes in the environment,” she says. “What we do know is that our climate system is very complex, that human activity is making Earth warmer, and that any technological fix we might try to shade the planet could have unforeseen consequences.”

Scientists Eye Longer-Term Forecasts of U.S. Heat Waves (Science Daily)

Oct. 27, 2013 — Scientists have fingerprinted a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance.

This map of air flow a few miles above ground level in the Northern Hemisphere shows the type of wavenumber-5 pattern associated with US drought. This pattern includes alternating troughs (blue contours) and ridges (red contours), with an “H” symbol (for high pressure) shown at the center of each of the five ridges. High pressure tends to cause sinking air and suppress precipitation, which can allow a heat wave to develop and intensify over land areas. (Credit: Image courtesy Haiyan Teng.)

The new research, led by scientists at the National Center for Atmospheric Research (NCAR), could potentially enable forecasts of the likelihood of U.S. heat waves 15-20 days out, giving society more time to prepare for these often-deadly events.

The research team discerned the pattern by analyzing a 12,000-year simulation of the atmosphere over the Northern Hemisphere. During those times when a distinctive “wavenumber-5” pattern emerged, a major summertime heat wave became more likely to subsequently build over the United States.

“It may be useful to monitor the atmosphere, looking for this pattern, if we find that it precedes heat waves in a predictable way,” says NCAR scientist Haiyan Teng, the lead author. “This gives us a potential source to predict heat waves beyond the typical range of weather forecasts.”

The wavenumber-5 pattern refers to a sequence of alternating high- and low-pressure systems (five of each) that form a ring circling the northern midlatitudes, several miles above the surface. This pattern can lend itself to slow-moving weather features, raising the odds for stagnant conditions often associated with prolonged heat spells.

The study is being published next week in Nature Geoscience. It was funded by the U.S. Department of Energy, NASA, and the National Science Foundation (NSF), which is NCAR’s sponsor. NASA scientists helped guide the project and are involved in broader research in this area.

Predicting a lethal event

Heat waves are among the most deadly weather phenomena on Earth. A 2006 heat wave across much of the United States and Canada was blamed for more than 600 deaths in California alone, and a prolonged heat wave in Europe in 2003 may have killed more than 50,000 people.

To see if heat waves can be triggered by certain large-scale atmospheric circulation patterns, the scientists looked at data from relatively modern records dating back to 1948. They focused on summertime events in the United States in which daily temperatures reached the top 2.5 percent of weather readings for that date across roughly 10 percent or more of the contiguous United States. However, since such extremes are rare by definition, the researchers could identify only 17 events that met such criteria — not enough to tease out a reliable signal amid the noise of other atmospheric behavior.

The group then turned to an idealized simulation of the atmosphere spanning 12,000 years. The simulation had been created a couple of years before with a version of the NCAR-based Community Earth System Model, which is funded by NSF and the Department of Energy.

By analyzing more than 5,900 U.S. heat waves simulated in the computer model, they determined that the heat waves tended to be preceded by a wavenumber-5 pattern. This pattern is not caused by particular oceanic conditions or heating of Earth’s surface, but instead arises from naturally varying conditions of the atmosphere. It was associated with an atmospheric phenomenon known as a Rossby wave train that encircles the Northern Hemisphere along the jet stream.

During the 20 days leading up to a heat wave in the model results, the five ridges and five troughs that make up a wavenumber-5 pattern tended to propagate very slowly westward around the globe, moving against the flow of the jet stream itself. Eventually, a high-pressure ridge moved from the North Atlantic into the United States, shutting down rainfall and setting the stage for a heat wave to emerge.

When wavenumber-5 patterns in the model were more amplified, U.S. heat waves became more likely to form 15 days later. In some cases, the probability of a heat wave was more than quadruple what would be expected by chance.

In follow-up work, the research team turned again to actual U.S. heat waves since 1948. They recognized that some historical heat wave events are indeed characterized by a large-scale circulation pattern that indicated a wavenumber-5 event.

Extending forecasts beyond 10 days

The research finding suggests that scientists are making progress on a key meteorological goal: forecasting the likelihood of extreme events more than 10 days in advance. At present, there is very limited skill in such long-term forecasts.

Previous research on extending weather forecasts has focused on conditions in the tropics. For example, scientists have found that El Niño and La Niña, the periodic warming and cooling of surface waters in the central and eastern tropical Pacific Ocean, are correlated with a higher probability of wet or dry conditions in different regions around the globe. In contrast, the wavenumber-5 pattern does not rely on conditions in the tropics. However, the study does not exclude the possibility that tropical rainfall could act to stimulate or strengthen the pattern.

Now that the new study has connected a planetary wave pattern to a particular type of extreme weather event, Teng and her colleagues will continue searching for other circulation patterns that may presage extreme weather events.

“There may be sources of predictability that we are not yet aware of,” she says. “This brings us hope that the likelihood of extreme weather events that are damaging to society can be predicted further in advance.”

The cultures endangered by climate change (PLOS)

Posted: September 9, 2013

By Greg Downey

The Bull of Winter weakens

In 2003, after decades of working with the Viliui Sakha, indigenous horse and cattle breeders in the Vilyuy River region of northeastern Siberia, anthropologist Susan Crate began to hear the local people complain about climate change:

My own “ethnographic moment” occurred when I heard a Sakha elder recount the age-old story of Jyl Oghuha (the bull of winter). Jyl Oghuha’s legacy explains the 100o C annual temperature range of Sakha’s subarctic habitat. Sakha personify winter, the most challenging season for them, in the form of a white bull with blue spots, huge horns, and frosty breath. In early December this bull of winter arrives from the Arctic Ocean to hold temperatures at their coldest (-60o to -65o C; -76o to -85o F) for December and January. Although I had heard the story many times before, this time it had an unexpected ending… (Crate 2008: 570)

This Sakha elder, born in 1935, talked about how the bull symbolically collapsed each spring, but also its uncertain future:

The bull of winter is a legendary Sakha creature whose presence explains the turning from the frigid winter to the warming spring. The legend tells that the bull of winter, who keeps the cold in winter, loses his first horn at the end of January as the cold begins to let go to warmth; then his second horn melts off at the end of February, and finally, by the end of March, he loses his head, as spring is sure to have arrived. It seems that now with the warming, perhaps the bull of winter will no longer be. (ibid.)

Crate found that the ‘softening’ of winter disrupted the Sakha way of life in a number of ways far less prosaic. The winters were warmer, bringing more rain and upsetting the haying season; familiar animals grew less common and new species migrated north; more snow fell, making hunting more difficult in winter; and when that snow thawed, water inundated their towns, fields, and countryside, rotting their houses, bogging down farming, and generally making life more difficult. Or, as a Sakha elder put it to Crate:

I have seen two ugut jil (big water years) in my lifetime. One was the big flood in 1959 — I remember canoeing down the street to our kin’s house. The other is now. The difference is that in ‘59 the water was only here for a few days and now it does not seem to be going away. (Sakha elder, 2009; in Crate 2011: 184).

(Currently, Eastern Russia is struggling with unprecedented flooding along the Chinese border, and, in July, unusual forest fires struck areas of the region that were permafrost.) As I write this, the website CO2 Now reports that the average atmospheric CO2 level for July 2013 at the Mauna Loa Observatory was 397.23 parts per million, slightly below the landmark 400+ ppm levels recorded in May. The vast majority of climate scientists now argue, not about whether we will witness anthropogenic atmospheric change, but how much and how quicklythe climate will change. Will we cross potential ‘tipping points’, when feedback dynamics accelerate the pace of warming?

While climate science might be controversial with the public in the US (less so here in Australia and among scientists), the effects on human populations are more poorly understood and unpredictable, both by the public and scientists alike. Following on from Wendy Foden and colleagues’ piece in the PLOS special collection proposing a method to identify the species at greatest risk (Foden et al. 2013), I want to consider how we might identify which cultures are at greatest risk from climate change.

Will climate change threaten human cultural diversity, and if so, which groups will be pushed to the brink most quickly? Are groups like the Viliui Sakha at the greatest risk, especially as we know that climate change is already affecting the Arctic and warming may be exaggerated there? And what about island groups, threatened by sea level changes? Who will have to change most and adapt because of a shifting climate? Daniel Lende (2013: 496) has suggested that anthropologists need to put our special expertise to work in public commentary, and in the area of climate change, these human impacts seem to be one place where that expertise might be most useful.

The Sakha Republic

The Sakha Republic where the Viliui Sakha live is half of Russia’s Far Eastern Federal District, a district that covers an area almost as large as India, twice the size of Alaska. Nevertheless, fewer than one million people live there, spread thinly across the rugged landscape. The region contains the coldest spot on the planet, the Verkhoyansk Range, where the average January temperature —average — is around -50O, so cold that it doesn’t matter whether that’s Fahrenheit or Celsius.

The area that is now the Sakha Republic was first taken control by Tsarist Russia in the seventeenth century, a tax taken from the local people in furs. Many early Russian migrants to the region adopted Sakha customs. Both the Tsars and the later Communist governors exiled criminals to the region, which came to be called Yakutia; after the fall of the Soviet Union, the Russian Federation recognised the Sakha Republic. The Sakha, also called Yakuts, are the largest group in the area today; since the fall of the Soviets, many of the ethnic Russian migrants have left.

Sakha speakers first migrated north into Siberia as reindeer hunters, mixing with and eventually assimilating the Evenki, a Tungus-speaking group that lived there nomadically. Then these nomadic groups were later assimilated or forced further north by more sedentary groups of Sakha who raised horses and practiced more intensive reindeer herding and some agriculture (for more information see Susan Crate’s excellent discussion, ‘The Legacy of the Viliui Reinfeer-Herding Complex’ at Cultural Survival). The later migrants forced those practicing the earlier, nomadic reindeer-herding way of life into the most remote and rugged pockets of the region. By the first part of the twentieth century, Crate reports, the traditional reindeer-herding lifestyle was completely replaced in the Viliui watershed, although people elsewhere in Siberia continued to practice nomadic lifestyles, following herds of reindeer.

Today the economy of the Sakha Republic relies heavily on mining: gold, tin, and especially diamonds. Almost a quarter of all diamonds in the world — virtually all of Russia’s production — comes from Sakha. The great Udachnaya pipe, a diamond deposit just outside the Arctic circle, is now the third deepest open pit mine in the world, extending down more than 600 meters.

A new project promises to build a pipeline to take advantage of the massive Chaynda gas field in Sakha, sending the gas eastward to Vladivostok on Russia’s Pacific coast (story in the Siberia Times). The $24 billion Gazprom pipeline, which President Putin’s office says he wants developed ‘within the tightest possible timescale’, would mean that Russia would not have to sell natural gas exclusively through Europe, opening a line for direct delivery into the Pacific.

The Sakha have made the transition to the post-Soviet era remarkably well, with a robust economy and a political system that seems capable of balancing development and environmental safeguards (Crate 2003). But after successfully navigating a political thaw, will the Sakha, and other indigenous peoples of the region, fall victim to a much more literal warming?

The United Nations on indigenous people and climate change

This past month, we celebrated the International Day of the World’s Indigenous People (9 August). From 2005 to 2014, the United Nations called for ‘A Decade for Action and Dignity.’ The focus of this year’s observance is ‘Indigenous peoples building alliances: Honouring treaties, agreements and other constructive arrangements’ (for more information, here’s the UN’s website). According to the UN Development Programme, the day ‘presents an opportunity to honour diverse indigenous cultures and recognize the achievements and valuable contributions of an estimated 370 million indigenous peoples.’

The UN has highlighted the widespread belief that climate change will be especially cruel to indigenous peoples:

Despite having contributed the least to GHG [green house gas], indigenous peoples are the ones most at risk from the consequences of climate change because of their dependence upon and close relationship with the environment and its resources. Although climate change is regionally specific and will be significant for indigenous peoples in many different ways, indigenous peoples in general are expected to be disproportionately affected. Indigenous communities already affected by other stresses (such as, for example, the aftermath of resettlement processes), are considered especially vulnerable. (UN 2009: 95)

The UN’s report, State of the World’s Indigenous People, goes on to cite the following specific ‘changes or even losses in the biodiversity of their environment’ for indigenous groups, that will directly threaten aspects of indigenous life:

  • the traditional hunting, fishing and herding practices of indigenous peoples, not only in the Arctic, but also in other parts of the world;

  • the livelihood of pastoralists worldwide;

  • the traditional agricultural activities of indigenous peoples living in mountainous regions;

  • the cultural and ritual practices that are not only related to specific species or specific annual cycles, but also to specific places and spiritual sites, etc.;

  • the health of indigenous communities (vector-borne diseases, hunger, etc.);

  • the revenues from tourism. (ibid.: 96)

For example, climate change has been linked to extreme drought in Kenya where the Maasai, pastoral peoples, find their herds shrinking and good pasture harder and harder to find. For the Kamayurá in the Xingu region of Brazil, less rain and warmer water have decimated fish stocks in their river and made cassava cultivation a hit and miss affair; children are reduced to eating ants on flatbread to stave off hunger.

The UN report touches on a number of different ecosystems where the impacts of climate change will be especially severe, singling out the Arctic:

The Arctic region is predicted to lose whole ecosystems, which will have implications for the use, protection and management of wildlife, fisheries, and forests, affecting the customary uses of culturally and economically important species and resources. Arctic indigenous communities—as well as First Nations communities in Canada—are already experiencing a decline in traditional food sources, such as ringed seal and caribou, which are mainstays of their traditional diet. Some communities are being forced to relocate because the thawing permafrost is damaging the road and building infrastructure. Throughout the region, travel is becoming dangerous and more expensive as a consequence of thinning sea ice, unpredictable freezing and thawing of rivers and lakes, and the delay in opening winter roads (roads that can be used only when the land is frozen). (ibid.: 97)

Island populations are also often pointed out as being on the sharp edge of climate change (Lazrus 2012). The award-winning film, ‘There Once Was an Island,’ focuses on a community in the Pacific at risk from a rise in the sea level. As a website for the film describes:

Takuu, a tiny atoll in Papua New Guinea, contains the last Polynesian culture of its kind.  Facing escalating climate-related impacts, including a terrifying flood, community members Teloo, Endar, and Satty, take us on an intimate journey to the core of their lives and dreams. Will they relocate to war-ravaged Bougainville – becoming environmental refugees – or fight to stay? Two visiting scientists investigate on the island, leading audience and community to a greater understanding of climate change.

Similarly, The Global Mail reported the island nation of Kiribati was likely to become uninhabitable in coming decades, not simply because the islands flood but because patterns of rainfall shift and seawater encroaches on the coastal aquifer, leaving wells saline and undrinkable.

Heather Lazrus (2012: 288) reviews a number of other cases:

Low-lying islands and coastal areas such as the Maldives; the Marshall Islands; the Federated States of Micronesia, Kiribati, and Tuvalu; and many arctic islands such as Shishmaref… and the small islands in Nunavut… may be rendered uninhabitable as sea levels rise and freshwater resources are reduced.

Certainly, the evidence from twentieth century cases in which whole island populations were relocated suggests that the move can be terribly disruptive, the social damage lingering long after suitcases are unpacked.

Adding climate injury to cultural insult

In fact, even before average temperatures climbed or sea levels rose, indigenous groups were already at risk and have been for a while. By nearly every available measure, indigenous peoples’ distinctive lifeways and the globe’s cultural diversity are threatened, not so much by climate, but by their wealthier, more technologically advanced neighbours, who often exercise sovereignty over them.

If we take language diversity as an index of cultural distinctiveness, for example, linguist Howard Krauss (1992: 4) warned in the early 1990s that a whole range of languages were either endangered or ‘moribund,’ no longer being learned by new speakers or young people. These moribund languages, Krauss pointed out, would inevitably die with a speaker who had already been born, an individual who would someday be unable to converse in that language because there would simply be no one else to talk to:

The Eyak language of Alaska now has two aged speakers; Mandan has 6, Osage 5, Abenaki-Penobscot 20, and Iowa has 5 fluent speakers. According to counts in 1977, already 13 years ago, Coeur d’Alene had fewer than 20, Tuscarora fewer than 30, Menomini fewer than 50, Yokuts fewer than 10. On and on this sad litany goes, and by no means only for Native North America. Sirenikski Eskimo has two speakers, Ainu is perhaps extinct. Ubykh, the Northwest Caucasian language with the most consonants, 80-some, is nearly extinct, with perhaps only one remaining speaker. (ibid.)

Two decades ago, Krauss went on to estimate that 90% of the Arctic indigenous languages were ‘moribund’; 80% of the Native North American languages; 90% of Aboriginal Australian languages (ibid.: 5). Although the estimate involved a fair bit of guesswork, and we have seen some interesting evidence of ‘revivals’, Krauss suggested that 50% of all languages on earth were in danger of disappearing.

The prognosis may not be quite as grim today, but the intervening years have confirmed the overall pattern. Just recently, The Times of India reported that the country has lost 20% of its languages since 1961 — 220 languages disappeared in fifty years, with the pace accelerating. The spiffy updated Ethnologue website, based upon a more sophisticated set of categories and more precise accounting, suggests that, of the 7105 languages that they recognise globally, around 19% are ‘moribund’ or in worse shape, while another 15% are shrinking but still being taught to new users (see Ethnologue’s discussion of language status here  and UNESCO’s interactive atlas of endangered languages).

Back in 2010, I argued that the disappearance of languages was a human rights issue, not simply the inevitable by-product of cultural ‘evolution’, economic motivations, and globalisation (‘Language extinction ain’t no big thing?’ – butbeware as my style of blogging has changed a lot since then). Few peoples voluntarily forsake their mother tongues; the disappearance of a language or assimilation of a culture is generally not a path strode by choice, but a lessor-of-evils choice when threatened with chronic violence, abject poverty, and marginalisation.

I’ve also written about the case of ‘uncontacted’ Indians on the border of Brazil and Peru, where Western observers sometimes assume that indigenous peoples assimilate because they seek the benefits of ‘modernization’ when, in fact, they are more commonly the victims of exploitation and violent displacement. Just this June, a group of Mashco-Piro, an isolated indigenous group in Peru that has little contact with other societies, engaged in a tense stand-off at the Las Piedras river, a tributary of the Amazon. Caught on video, they appeared to be trying to contact or barter with local Yine Indians at a ranger station. Not only have this group of the Mashco-Piro fought in previous decades with loggers, but they now find that low-flying planes are disturbing their territory in search of natural gas and oil. (Globo Brasil also released footage taken in 2011 by officials from Brazil’s National Indian Foundation, FUNAI, of the Kawahiva, also called the Rio Pardo Indians, an isolated group from Mato Grosso state.)

In 1992, Krauss pleaded with fellow scholars to do something about the loss of cultural variation, lest linguistics ‘go down in history as the only science that presided obliviously over the disappearance of 90% of the very field to which it is dedicated’ (1992: 10):

Surely, just as the extinction of any animal species diminishes our world, so does the extinction of any language. Surely we linguists know, and the general public can sense, that any language is a supreme achievement of a uniquely human collective genius, as divine and endless a mystery as a living organism. Should we mourn the loss of Eyak or Ubykh any less than the loss of the panda or California condor? (ibid.: 8)

The pace of extinction is so quick that some activists, like anthropologist and attorney David Lempert (2010), argue that our field needs to collaborate on the creation of a cultural ‘Red Book,’ analogous to the Red Book for Endangered Species. Anthropologists may fight over the theoretical consequences of reifying cultures, but the political and legal reality is that even states with laws on the books to protect cultural diversity often have no clear guidelines as to what that entails.

But treating cultures solely as fragile victims of climate change misrepresents how humans will adapt to climate change. Culture is not merely a fixed tradition, calcified ‘customs’ at risk from warming; culture is also out adaptive tool, the primary way in which our ancestors adapted to such a great range of ecological niches in the first place and we will continue to adapt into the future. And this is not the first time that indigenous groups have confronted climate change.

Culture as threatened, culture as adaptation

One important stream of research in the anthropology of climate change shows very clearly that indigenous cultures are quite resilient in the face of environmental change. Anthropologist Sarah Strauss of the University of Wyoming has cautioned that, if we only focus on cultural extinction from climate change as a threat, we may miss the role of culture in allowing people toaccommodate wide variation in the environment:

People are extraordinarily resilient. Our cultures have allowed human groups to colonize the most extreme reaches of planet Earth, and no matter where we have gone, we have contended with both environmental and social change…. For this reason, I do not worry that the need to adapt to new and dramatic environmental changes (those of our own making, as well as natural occurrences like volcanoes) will drive cultures—even small island cultures—to disappear entirely.  (Strauss 2012: n.p. [2])

A number of ethnographic cases show how indigenous groups can adapt to severe climatic shifts. Crate (2008: 571), for example, points out that the Sakha adapted to a major migration northward, transforming a Turkic culture born in moderate climates to suit their new home. Kalaugher (2010) also discusses the Yamal Nenets, another group of Siberian nomads, who adapted to both climate change and industrial encroachment, including the arrival of oil and gas companies that fouled waterways and degraded their land (Survival International has a wonderful photo essay about the Yamal Nenets here.). A team led by Bruce Forbes of the University of Lapland, Finland, found:

The Nenet have responded by adjusting their migration routes and timing, avoiding disturbed and degraded areas, and developing new economic practices and social interaction, for example by trading with workers who have moved into gas villages in the area. (article here)

But one of the most amazing stories about the resilience and adaptability of the peoples of the Arctic comes from Wade Davis, anthropologist and National Geographic ‘explorer in residence.’ In his wonderful TED presentation, ‘Dreams from endangered cultures,’ Davis tells a story he heard on a trip to the northern tip of Baffin Island, Canada:

…this man, Olayuk, told me a marvelous story of his grandfather. The Canadian government has not always been kind to the Inuit people, and during the 1950s, to establish our sovereignty, we forced them into settlements. This old man’s grandfather refused to go. The family, fearful for his life, took away all of his weapons, all of his tools. Now, you must understand that the Inuit did not fear the cold; they took advantage of it. The runners of their sleds were originally made of fish wrapped in caribou hide. So, this man’s grandfather was not intimidated by the Arctic night or the blizzard that was blowing. He simply slipped outside, pulled down his sealskin trousers and defecated into his hand. And as the feces began to freeze, he shaped it into the form of a blade. He put a spray of saliva on the edge of the shit knife, and as it finally froze solid, he butchered a dog with it. He skinned the dog and improvised a harness, took the ribcage of the dog and improvised a sled, harnessed up an adjacent dog, and disappeared over the ice floes, shit knife in belt. Talk about getting by with nothing.

… and there’s nothing more than I can say after ‘… and disappeared over the ice floes, shit knife in belt’ that can make this story any better…

Climate change in context

The problem for many indigenous cultures is not climate change alone or in isolation, but the potential speed of that change and how it interacts with other factors, many human-induced: introduced diseases, environmental degradation, deforestation and resource depletion, social problems such as substance abuse and domestic violence, and legal systems imposed upon them, including forced settlement and forms of property that prevent movement. As Strauss explains:

Many researchers… see climate change not as a separate problem, in fact, but rather as an intensifier, which overlays but does not transcend the rest of the challenges we face; it is therefore larger in scale and impact, perhaps, but not entirely separable from the many other environmental and cultural change problems already facing human societies. (Strauss 2012: n.p. [2])

One of the clearest examples of these intensifier effects is the way in which nomadic peoples, generally quite resilient, lose their capacity to adapt when they are prevented from moving. The Siberian Yamal Nenets makes this clear:

“We found that free access to open space has been critical for success, as each new threat has arisen, and that institutional constraints and drivers were as important as the documented ecological changes,” said Forbes. “Our findings point to concrete ways in which the Nenets can continue to coexist as their lands are increasingly fragmented by extensive natural gas production and a rapidly warming climate.” (Kalaugher 2010)

With language loss in India, it’s probably no coincidence that, ‘Most of the lost languages belonged to nomadic communities scattered across the country’ (Times of India).

In previous generations, if climate changed, nomadic groups might have migrated to follow familiar resources or adopt techniques from neighbours who had already adapted to forces novel to them. An excellent recent documentary series on the way that Australian Aboriginal people have adapted to climate change on our continent — the end of an ice age, the extinction of megafauna, wholesale climate change including desertification — is a striking example (the website for the series, First Footprints, is excellent).

Today, migration is treated by UN officials and outsiders as ‘failure to adapt’, as people who move fall under the new rubric of ‘climate refugees’ (Lazrus 2012: 293). Migration, instead of being recognised as an adaptive strategy, is treated as just another part of the diabolical problem. (Here in Australia, where refugees on boats trigger unmatched political hysteria, migration from neighbouring areas would be treated as a national security problem rather than an acceptable coping strategy.)

For the most part, the kind of migration that first brought the Viliui Sakha to northeastern Siberia is no longer possible. As the Yamal Nenets, for example, migrate with their herds of reindeer, the come across the drills, pipelines, and even the Obskaya-Bovanenkovo railway – the northern-most railway line in the world – all part of Gazprom’s ‘Yamal Megaproject.’  Endangered indigenous groups are hemmed in on all sides, surviving only in geographical niches that were not attractive to their dominant neighbours, unsuitable for farming. AsElisabeth Rosenthal wrote in The New York Times:

Throughout history, the traditional final response for indigenous cultures threatened by untenable climate conditions or political strife was to move. But today, moving is often impossible. Land surrounding tribes is now usually occupied by an expanding global population, and once-nomadic groups have often settled down, building homes and schools and even declaring statehood.

For the Kamayurá, for example, eating ants instead of fish in Brazil’s Xingu National Park, they are no longer surrounded by the vast expanse of the Amazon and other rivers where they might still fish; the park is now surrounded by ranches and farms, some of which grow sugarcane to feed Brazil’s vast ethanol industry or raise cattle to feed the world’s growing appetite for beef.

Now, some of these indigenous groups find themselves squarely in the path of massive new resource extraction projects with nowhere to go, whether that’s in northern Alberta, eastern Peru, Burma, or remnant forests in Indonesia. That is, indigenous peoples have adapted before to severe climate change; but how much latitude (literally) do these groups now have to adapt if we do not allow them to move?

In sum, indigenous people are often not directly threatened by climate change alone; rather, they are pinched between climate change and majority cultures who want Indigenous peoples’ resources while also preventing them from adapting in familiar ways. The irony is that the dynamic driving climate change is attacking them from two sides: the forests that they need, the mountains where they keep their herds, and the soil under the lands where they live are being coveted for the very industrial processes that belch excess carbon into the atmosphere.

It’s hard not to be struck by the bitter tragedy that, in exchange for the resources to which we are addicted, we offer them assimilation. If they get out of the way so that we can drill out the gas or oil under their land or take their forests, we will invite them in join in our addiction (albeit, as much poorer addicts on the fringes of our societies, if truth be told). They have had little say in the process, or in our efforts to mitigate the process. We assume that our technologies and ways of life are the only potential cure for the problems created by these very technologies and ways of life.

In 2008, for example, Warwick Baird, Director of the Native Title Unit of the Australian Human Rights and Equal Opportunity Commission, warned that the shift to an economic mode of addressing climate change abatement threatened to further sideline indigenous people:

Things are moving fast in the world of climate change policy and the urgency is only going to get greater. Yet Indigenous peoples, despite their deep engagement with the land and waters, it seems to me, have little engagement with the formulation of climate change policy little engagement in climate change negotiations ­ and little engagement in developing and applying mitigation and adaptation strategies. They have not been included. Human rights have not been at the forefront. (transcript of speech here)

The problem then is not that indigenous populations are especially fragile or unable to adapt; in fact, both human prehistory and history demonstrate that these populations are remarkably resilient. Rather, many of these populations have been pushed to the brink, forced to choose between assimilation or extinction by the unceasing demands of the majority cultures they must live along side. The danger is not that the indigenous will fall off the precipice, but rather that the flailing attempts of the resource-thirsty developed world toavoid inevitable culture change — the necessary move away from unsustainable modes of living — will push much more sustainable lifeways over the edge into the abyss first.

Secretária-executiva de painel da ONU chora ao falar sobre mudanças climáticas (O Globo)

23 de outubro de 2013

Christiana Figueres, chefe do IPCC, ficou emocionada ao falar sobre impacto das alterações nas futuras gerações em conferência em Londres

Secretária-executiva do Painel Intergovernamental sobre Mudanças Climáticas da ONU (IPCC), a costa-riquenha Christiana Figueres fez uma defesa apaixonada das negociações em torno de um novo acordo global para combater o problema em conferência nesta segunda-feira em Londres. Em seu discurso durante o evento, Figueres reclamou da lentidão nas conversas, mas mostrou-se otimista quanto à possibilidade de em 2015 ser assinado um acerto que obrigue o cumprimento de metas de redução da emissão de gases do efeito estufa pelos principais países poluidores do mundo a partir de 2020.

– Sempre fico frustrada com o ritmo das negociações, nasci impaciente – disse Figueres. – Estamos avançando muito, muito devagar, mas estamos indo na direção certa e é isso que me dá coragem e esperança.

E Figueres manteve o tom apaixonado depois do discurso. Abordada por um repórter da rede britânica de TV BBC, que lhe perguntou sobre o impacto das mudanças climáticas, ela ficou emocionada e chegou a chorar.

– Estou comprometida com (a luta contra) as mudanças climáticas por causa das futuras gerações e não por nós, certo? Nós estamos partindo daqui – disse. – Simplesmente sinto que é totalmente injusto e imoral o que estamos fazendo com as futuras gerações. Estamos condenando elas antes mesmo de elas nascerem. Mas temos uma escolha sobre isso, esta é a questão, temos uma escolha. Se (as mudanças climáticas) forem inevitáveis, então que sejam, mas temos a escolha de tentar mudar o futuro que vamos dar às nossas crianças.

Carbon Cycle Models Underestimate Indirect Role of Animals (Science Daily)

Oct. 16, 2013 — Animal populations can have a far more significant impact on carbon storage and exchange in regional ecosystems than is typically recognized by global carbon models, according to a new paper authored by researchers at the Yale School of Forestry & Environmental Studies (F&ES). 

Wildebeests herd, Serengeti. Scientists found that a decline in wildebeest populations in the Serengeti-Mara grassland-savanna system decades ago allowed organic matter to accumulate, which eventually led to about 80 percent of the ecosystem to burn annually, releasing carbon from the plants and the soil, before populations recovered in recent years.

In fact, in some regions the magnitude of carbon uptake or release due to the effects of specific animal species or groups of animals — such as the pine beetles devouring forests in western North America — can rival the impact of fossil fuel emissions for the same region, according to the paper published in the journal Ecosystems.

While models typically take into account how plants and microbes affect the carbon cycle, they often underestimate how much animals can indirectly alter the absorption, release, or transport of carbon within an ecosystem, says Oswald Schmitz, the Oastler Professor of Population and Community Ecology at F&ES and lead author of the paper. Historically, the role of animals has been largely underplayed since animal species are not distributed globally and because the total biomass of animals is vastly lower than the plants that they rely upon, and therefore contribute little carbon in the way of respiration.

“What these sorts of analyses have not paid attention to is what we call the indirect multiplier effects,” Schmitz says. “And these indirect effects can be quite huge — and disproportionate to the biomass of the species that are instigating the change.”

In the paper, “Animating the Carbon Cycle,” a team of 15 authors from 12 universities, research organizations and government agencies cites numerous cases where animals have triggered profound impacts on the carbon cycle at local and regional levels.

In one case, an unprecedented loss of trees triggered by the pine beetle outbreak in western North America has decreased the net carbon balance on a scale comparable to British Columbia’s current fossil fuel emissions.

And in East Africa, scientists found that a decline in wildebeest populations in the Serengeti-Mara grassland-savanna system decades ago allowed organic matter to accumulate, which eventually led to about 80 percent of the ecosystem to burn annually, releasing carbon from the plants and the soil, before populations recovered in recent years.

“These are examples where the animals’ largest effects are not direct ones,” Schmitz says. “But because of their presence they mitigate or mediate ecosystem processes that then can have these ramifying effects.”

“We hope this article will inspire scientists and managers to include animals when thinking of local and regional carbon budgets,” said Peter Raymond, a professor of ecosystem ecology at the Yale School of Forestry & Environmental Studies.

According to the authors, a more proper assessment of such phenomena could provide insights into management schemes that could help mitigate the threat of climate change.

For example, in the Arctic, where about 500 gigatons of carbon is stored in permafrost, large grazing mammals like caribou and muskoxen can help maintain the grasslands that have a high albedo and thus reflect more solar energy. In addition, by trampling the ground these herds can actually help reduce the rate of permafrost thaw, researchers say.

“It’s almost an argument for rewilding places to make sure that the natural balance of predators and prey are there,” Schmitz says. “We’re not saying that managing animals will offset these carbon emissions. What we’re trying to say is the numbers are of a scale where it is worthwhile to start thinking about how animals could be managed to accomplish that.”

Terrestrial Ecosystems at Risk of Major Shifts as Temperatures Increase (Science Daily)

Oct. 8, 2013 — Over 80% of the world’s ice-free land is at risk of profound ecosystem transformation by 2100, a new study reveals. “Essentially, we would be leaving the world as we know it,” says Sebastian Ostberg of the Potsdam Institute for Climate Impact Research, Germany. Ostberg and collaborators studied the critical impacts of climate change on landscapes and have now published their results inEarth System Dynamics, an open access journal of the European Geosciences Union (EGU).

This image shows simulated ecosystem change by 2100, depending on the degree of global temperature increase: 2 degrees Celsius (upper image) or five degrees Celsius (lower image) above preindustrial levels. The parameter “ (Gamma) measures how far apart a future ecosystem under climate change would be from the present state. Blue colours (lower “) depict areas of moderate change, yellow to red areas (higher “) show major change. The maps show the median value of the “ parameter across all climate models, meaning at least half of the models agree on major change in the yellow to red areas, and at least half of the models are below the threshold for major change in the blue areas. (Credit: Ostberg et al., 2013)

The researchers state in the article that “nearly no area of the world is free” from the risk of climate change transforming landscapes substantially, unless mitigation limits warming to around 2 degrees Celsius above preindustrial levels.

Ecosystem changes could include boreal forests being transformed into temperate savannas, trees growing in the freezing Arctic tundra or even a dieback of some of the world’s rainforests. Such profound transformations of land ecosystems have the potential to affect food and water security, and hence impact human well-being just like sea level rise and direct damage from extreme weather events.

The new Earth System Dynamics study indicates that up to 86% of the remaining natural land ecosystems worldwide could be at risk of major change in a business-as-usual scenario (see note). This assumes that the global mean temperature will be 4 to 5 degrees warmer at the end of this century than in pre-industrial times — given many countries’ reluctance to commit to binding emissions cuts, such warming is not out of the question by 2100.

“The research shows there is a large difference in the risk of major ecosystem change depending on whether humankind continues with business as usual or if we opt for effective climate change mitigation,” Ostberg points out.

But even if the warming is limited to 2 degrees, some 20% of land ecosystems — particularly those at high altitudes and high latitudes — are at risk of moderate or major transformation, the team reveals.

The researchers studied over 150 climate scenarios, looking at ecosystem changes in nearly 20 different climate models for various degrees of global warming. “Our study is the most comprehensive and internally consistent analysis of the risk of major ecosystem change from climate change at the global scale,” says Wolfgang Lucht, also an author of the study and co-chair of the research domain Earth System Analysis at the Potsdam Institute for Climate Impact Research.

Few previous studies have looked into the global impact of raising temperatures on ecosystems because of how complex and interlinked these systems are. “Comprehensive theories and computer models of such complex systems and their dynamics up to the global scale do not exist.”

To get around this problem, the team measured simultaneous changes in the biogeochemistry of terrestrial vegetation and the relative abundance of different vegetation species. “Any significant change in the underlying biogeochemistry presents an ecological adaptation challenge, fundamentally destabilising our natural systems,” explains Ostberg.

The researchers defined a parameter to measure how far apart a future ecosystem under climate change would be from the present state. The parameter encompasses changes in variables such as the vegetation structure (from trees to grass, for example), the carbon stored in the soils and vegetation, and freshwater availability. “Our indicator of ecosystem change is able to measure the combined effect of changes in many ecosystem processes, instead of looking only at a single process,” says Ostberg.

He hopes the new results can help inform the ongoing negotiations on climate mitigation targets, “as well as planning adaptation to unavoidable change.”

Note

Even though 86% of land ecosystems are at risk if global temperature increases by 5 degrees Celsius by 2100, it is unlikely all these areas will be affected. This would mean that the worst case scenario from each climate model comes true.

Native Tribes’ Traditional Knowledge Can Help US Adapt to Climate Change (Science Daily)

Oct. 3, 2013 — New England’s Native tribes, whose sustainable ways of farming, forestry, hunting and land and water management were devastated by European colonists four centuries ago, can help modern America adapt to climate change.

That’s the conclusion of more than 50 researchers at Dartmouth and elsewhere in a special issue of the journal Climatic Change. It is the first time a peer-reviewed journal has focused exclusively on climate change’s impacts on U.S. tribes and how they are responding to the changing environments. Dartmouth also will host an Indigenous Peoples Climate Change Working Group meeting Nov. 4- 5.

The special issue, which includes 13 articles, concludes that tribes’ traditional ecological knowledge can play a key role in developing scientific solutions to adapt to the impacts. “The partnerships between tribal peoples and their non-tribal research allies give us a model for responsible and respectful international collaboration,” the authors say.

Dartmouth assistant professors Nicholas Reo and Angela Parker, whose article is titled “Re-thinking colonialism to prepare for the impacts of rapid environmental change,” said New England settlers created a cascade of environmental and human changes that spread across North America, including human diseases, invasive species, deforestation and overharvest.

The researchers identified social and ecological tipping points and feedback loops that amplify and mitigate environmental change. For example, prior to the arrival of Europeans, old growth deciduous forests were rich with animal and plant resources and covered more than 80 percent of New England. Native peoples helped to sustain this bountiful biodiversity for centuries through their land practices.

“But when indigenous communities were decimated by disease and eventually alienated from their known environments, land tenure innovations based on deep, local ecological knowledge, disappeared,” the researchers say. “Colonists, and their extractive systems aimed at key animal and plant species, became the new shapers of cultural landscapes. Rapid ecological degradation subsequently ensued, and New Englanders created a difficult project of stewarding a far less resilient landscape without help from indigenous land managers who would have known best how to enact ecological restoration measures.”

Today’s tribal members who work with natural resources, such as fisherman, farmers and land managers, can play key roles in devising local and regional strategies to adapt to climate change, the researchers say.

Demissões no Inpe comprometem a previsão do tempo, afirma sindicato (Portal G1, via Agência Ambiente Brasil)

JC e-mail 4825, de 02 de Outubro de 2013.

Se os contratos de 71 funcionários forem suspensos, o Centro de Previsão do Tempo e Estudos Climáticos vai perder mais de um terço da mão de obra

A 10 dias para o fim do prazo determinado pela Justiça para a demissão de servidores contratados irregularmente pelo Instituto Nacional de Pesquisas Espaciais (Inpe), ligado ao Ministério da Ciência, Tecnologia e Inovação (MCTI), o governo federal ainda não definiu a liberação de vagas para abertura de um concurso público. Se os contratos de 71 funcionários forem suspensos a partir de 11 de outubro, o Centro de Previsão do Tempo e Estudos Climáticos (Cptec), em Cachoeira Paulista (SP), vai perder mais de um terço da mão de obra – o centro é o mais avançado em previsão numérica de tempo e clima da América Latina.

O Sindicato dos Servidores Públicos Federais da área de Ciência e Tecnologia no setor Aerospacial (SindCT) cobra agilidade da direção do Inpe e dos Ministérios da Ciência, Tecnologia e Inovação e do Planejamento na solução do problema com o objetivo de tentar suspender temporariamente a decisão judicial. De acordo com a entidade, a previsão do tempo poderá ser comprometida. A direção do Inpe nega que isso vá ocorrer e aguarda a decisão do recurso protolado no Tribunal Regional Federal (TRF-SP) em que pede prolongamento do prazo para solucionar o problema dos contratos irregulares.

O Inpe foi notificado da nulidade dos contratos em 27 agosto e, na ocasião, a sentença definiu prazo de 45 dias para promover as demissões – o prazo termina no próximo dia 10. A ação do Ministério Público Federal (MPF) contesta 111 contratações feitas em caráter emergencial em 2010. Mas segundo Leonel Perondi, diretor do Inpe, um concurso realizado em 2012 possibilitou a substituição dos temporários e, atualmente, a situação se mantém irregular para um grupo de 71 servidores, entre os quais 52 que atuam na previsão do tempo. Outros nove profissionais trabalham no Laboratório de Combustão e Propulsão, onde testes de combustíveis para satélites são realizados. O Cptec tem atualmente um total de 146 servidores.

A maioria dos profissionais que serão desligados são meteorologistas, engenheiros analistas de sistemas e técnicos de computação. Parte dos funcionários que devem ter os contratos suspensos atuam na operação do Tupã, o supercomputador que custou R$ 50 milhões e ampliou a precisão das previsões de fenômenos climáticos extremos, como grandes temporais. O computador é o único no país, segundo o Inpe e, além do Cptec, também fornece informações ao Instituto Nacional Meteorologia (Inmet).

Os contratos dos servidores temporários, caso não houvesse intervenção judicial, terminaria entre os anos de 2014 e 2015. Segundo o instituto, nenhum servidor foi demitido até o momento.

Ameaça de paralisação – O Sindicato dos Servidores Públicos Federais da área de Ciência e Tecnologia no setor Aerospacial (SindCT) cobra agilidade. “Já se passou metade do prazo judicial para que as demissões aconteçam e as vagas não foram liberadas. Essa seria a única possibilidade de tentar suspender a decisão judicial. A previsão do tempo será comprometida, não temos efetivo para operar o Tupã e isso trará consequências a todo país, sobretudo na agricultura”, disse Fernando Morais, vice-presidente do SindCT.

A entidade informou que planeja fazer uma paralisação na próxima sexta-feira (4), envolvendo os 71 demissíveis na tentativa de sensibilizar o governo federal. “Não é possível esperar mais. Estive em Brasília para falar com as autoridades para tentar intervir no problema, mas é preciso que, se liberadas as vagas, esse edital seja lançado no dia seguinte”, afirmou Morais ao G1.

Segundo o presidente do Inpe, dois avisos ministeriais solicitando a abertura de concursos ao Ministério do Planejamento, Orçamento e Gestão foram enviados pelo instituto desde novembro do ano passado, mas nenhuma resposta foi obtida. O diretor do Inpe vai a Brasília nesta terça (1º) tentar negociar a liberação das vagas.

Prejuízo – Os dados e informações fornecidos pelo supercomputador Tupã geram previsões meteorológicas diárias e a longo prazo do tempo. As informações são usadas na agricultura, pelas prefeituras e Defesa Civil que recebem alertas de desastres naturais por meio do Centro Nacional de Monitoramento e Alertas de Desastres Naturais (Cemadem) e também pela aviação civil.

O supercomputador não pode ser desligado. “Essa máquina não foi feita para ser desligada, por isso está atrelada a geradores. O desligamento pode resultar em até 3 meses de serviço, envolvendo técnicos especializados, na tentativa de recuperá-lo. Isso vai envolver custos”, informou o vice-presidente do SindCT.

Ele destacou também que a abertura das vagas ameaçadas por meio de concurso público não traria impacto financeiro ao órgão. “Essas pessoas já tem seus salários inclusos na folha de pagamento do Inpe, não muda nada”, destacou.

De acordo com Perondi, a possibilidade de desligamento do supercomputador está descartada. Ele informa que espera que o recurso sensibilize a Justiça quanto ao prolongamento dos prazos e, que paralelamente, tem estudado medidas para manter o serviço de previsão do tempo.

“Acredito que será possível fazermos um termo de ajuste de conduta e mantermos esses profissionais nas suas atividades até a realização do concurso. Não se contempla a possibilidade de parar a previsão, são dados para áreas críticas do país, vamos estudar alternativas para suprir a eventual falta destes profissionais”, disse ao G1. Perondi acredita que o ideal seria prolongar o prazo para a regularização dos contratos em pelo menos um ano. O Inpe recebeu uma série de pedidos de órgãos como do Operador Nacional do Sistema Elétrico (ONS) e da Defesa Civil. Os documentos foram anexados no recurso.

Acusação – As contratações irregulares no Inpe aconteceram durante a gestão de Gilberto Câmara. O SindCT acusa o então gestor de negligenciar as recomendações jurídicas e promover as contratações irregulares. “Existia um parecer desaconselhando essas contratações. Ele criou um imbróglio, nunca brigou pelas vagas, nunca pediu pela abertura de concurso e agora temos esse problema”, denunciou Morais.

Em missão na Alemanha, Câmara entrou em contato com a reportagem nesta terça-feira (1º) e rebateu as acusações. Segundo ele, as contratações já ocorriam antes de sua gestão e as terceirizações questionadas pelo Ministério Público, que ocorreram em 2010, estavam respaldadas por parecer da Advocacia Geral da União (AGU). Ele também encaminhou ao G1 cópia de ofícios solicitando a abertura de vagas para o órgão em 2007 e 2009.

O ex-diretor questionou ainda o modelo de contratação exigido para o Inpe, considerado por ele um prejuízo para o país. “O país precisa do serviço prestado pelo Inpe e não de mais servidores públicos. O melhor regime seria a criação de uma organização social (OS), como ocorre em vários institutos que recebem missões do governo. Não faz sentido contratar servidor público para a vida inteira. Entendo que o interesse público está servido enquanto o Inpe tiver servidores qualificados, exercendo seus cargos”, defendeu.

O último concurso público do Inpe foi realizado em 2012 para o preenchimento de pouco mais de 100 vagas, incluindo a regularização dos 40 profissionais que corriam risco de terem os contratos suspensos. Antes deste concurso, um outro foi realizado em 2004.

A previsão é que até 2015, tendo como base a quantidade de 1.063 funcionários em atividade em 2010, o Inpe tenha uma redução de 36% no efetivo por motivo de aposentadoria. A idade média dos servidores é de 52 anos.

Entenda o caso – De acordo com o procurador Fernando Lacerda Dias, autor da proposta que resultou na anulação dos contratos, o Inpe fez manobras jurídicas proibidas pela lei para contratar pessoal. “Os contratos foram feitos com base em uma lei que autoriza essas contratações sem concurso. Mas é uma legislação específica para contratação temporária e não para funções de rotina, que é o que eles fizeram”, disse ao G1 no último dia 5.

O Inpe, ao longo dos anos, acumulou novas funções na sua área de atuação, mas o aumento de atribuições não foi acompanhado pela renovação de servidores, o que gerou defasagem quantitativa de mão de obra.

Na tentativa de resolver o problema, o órgão passou a contratar servidores terceirizados, com base no decreto 2.271/97. O procedimento é considerado ilegal, porque a terceirização de mão de obra não pode servir para suprir as atividades finalísticas de um órgão público.

Em 2006, a União se comprometeu a substituir gradualmente os funcionários terceirizados irregulares por servidores concursados, mas em 2009, próximo a expiração dos contratos existentes, o Inpe tentou nova contratação de servidores terceirizados.

A terceirização foi negada pelos órgãos internos de assessoramento jurídico do Inpe. Sem ter o concurso público aberto, o órgão alterou a forma jurídica das contratações, realizando processo seletivo para contratação temporária de 111 novos servidores, com base na lei 8.745/93. A manobra também foi considerada ilegal.

Outro lado – O ministro da Ciência e Tecnologia, Marco Antônio Raupp, foi procurado e informou, por meio de sua assessoria de imprensa que a pasta pleiteou a liberação das vagas para a abertura do concurso. A assessoria da pasta recomendou inicialmente que o G1 procurasse o Ministério do Planejamento para obter informações sobre a liberação das vagas,

O Ministério do Planejamento informou por e-mail que autorizou em 2013 o provimento de 832 vagas para o Ministério de Ciência, Tecnologia e Inovação, a quem compete realizar a distribuição das vagas entre seus vários institutos de pesquisa e que autorizações adicionais dependerão de novas tratativas com o MCTI.

Informado sobre o retorno do Ministério do Planejamento nesta quinta-feira (26), a assessoria de imprensa do Ministério de Ciência e Tecnologia não informou até a tarde desta segunda-feira (30) o destino destas vagas liberadas, nem se elas estão disponíveis para o Inpe.

Climate sceptics claim warming pause backs their view (BBC)

26 September 2013 Last updated at 00:47 GMT

By Matt McGrathEnvironment correspondent, BBC News, The Netherlands

Hurricane SandyCome hell or… An increased likelihood of extreme weather events is one predicted outcome of global warming, but some dispute the scale of expected effects

In the run up to a key global warming report, those sceptical of mainstream opinion on climate change claim they are “winning” the argument.

They say a slowing of temperature rises in the past 15 years means the threat from climate change is exaggerated.

But a leading member of the UN’s panel on climate change said the views of sceptics were “wishful thinking”.

Some of what the sceptics are saying is either wishful thinking or totally dishonest”

Prof Jean-Pascal van Ypersele, IPCC

The pause in warming was a distraction, he said, from the growing scientific certainty about long-term impacts.

Prof Jean Pascal van Ypersele spoke to BBC News ahead of the release of a six-yearly status report into global warming by the UN panel known as the Intergovernmental Panel on Climate Change, or IPCC.

Scientists and government representatives are currently meeting in Stockholm, Sweden, going through the dense, 31-page summary of the state of the physical science behind climate change.

When it is released on Friday, the report is likely to state with even greater certainty than before that the present-day, rapid warming of the planet is man-made.

But climate sceptics have focused their attention on the references to a pause or hiatus in the increase in global temperatures since 1998.

The sceptics believe that this slowdown is the most solid evidence yet that mainstream computer simulations of the Earth’s climate – climate models – are wrong.

These computer simulations are used to study the dynamics of the Earth’s climate and make projections about future temperature change.

“The sceptics now have a feeling of being on the winning side of the debate thanks to the pause,” said Marcel Crok, a Dutch author who accepts the idea that human activities warm the planet, but is sceptical about the scale of the effect.

“You are now starting to see a normalisation of climate science. Suddenly mainstream researchers, who all agree that greenhouse gases play a huge role, start to disagree about the cause of the pause.

“For me this is a relief, it is finally opening up again and this is good.”

The view that the sceptics have positively impacted the IPCC is supported by Prof Arthur Petersen, who is a member of the Dutch government team currently examining the report.

“The sceptics are good for the IPCC and the whole process is really flourishing because of this interaction over the past decades,” he told BBC News.

“Our best climate researchers are typically very close to really solid, sceptical scientists. In this sense scepticism is not necessarily a negative term.”

Others disagree.

Bart Verheggen is an atmospheric scientist and blogger who supports the mainstream view of global warming. He said that sceptics have discouraged an open scientific debate.

“When scientists start to notice that their science is being distorted in public by these people who say they are the champions of the scientific method, that could make mainstream researchers more defensive.

“Scientists probably think twice now about writing things down. They probably think twice about how this could be twisted by contrarians.”

Sensitive debate

In 2007, the IPCC defined the range for what’s termed “equilibrium climate sensitivity”. This term refers to the likely span of temperatures that would occur following a doubling of CO2 concentrations in the atmosphere.

The panel’s last report said temperatures were likely to rise within the range of 2C to 4.5C with a best estimate of 3C.

The new report is believed to indicate a range of 1.5C to 4.5C with no best estimate indicated.

Although that might not appear like much of a change, many sceptics believe it exposes a critical flaw.

“In the last year, we have seen several studies showing that climate sensitivity is actually much less than we thought for the last 30 years,” said Marcel Crok.

“And these studies indicate that our real climate shows a sensitivity of between 1.5C and 2C, but the climate models on which these future doom scenarios are based warm up three degrees under a doubling of CO2.”

But other researchers who are familiar with the text believe that the sceptics are reading too much into a single figure.

“Some of what the sceptics are saying is either wishful thinking or totally dishonest,” Prof van Ypersele, who is vice-chair of the IPCC, told BBC News.

“It is just a change in a lower border [of the range of temperature rise]. Even if this turns out to be the real sensitivity, instead of making the challenge extremely, extremely, extremely difficult to meet, it is only making it extremely, extremely difficult.

“Is that such a big change?”

Prof van Ypersele points out that many other aspects of the forthcoming report are likely to give greater certainty to the scale of impacts of a warming world. The predictions for sea level rise are likely to be considerably strengthened from 2007. There is also likely to be a clearer understanding of the state of sea ice.

Who are the climate sceptics?

Although there are only a small number of mainstream scientists who reject the established view on global warming, they are supported by a larger group of well resourced bloggers and citizen scientists who pore through climate literature and data looking for evidence of flaws in the hypothesis.

There are many different shades of opinion in the sceptical orbit. Some such as the group Principia Scientific reject the “myth” of greenhouse gas warming.

There are also political sceptics, such as some members of the Republican party in the US, who argue that climate science is a hoax or a conspiracy.

But there are also sceptical bloggers such as Anthony Watts and Andrew Montford who accept the basic science that adding carbon to the atmosphere can affect the temperature. They contest mainstream findings on the sensitivity of the climate to carbon and the future impacts on temperature.

The Dutch approach to sceptics

With around 20% of the country under sea level, the Dutch have a keen interest in anything that might affect their environment, such as climate change.

But scepticism about the human influence on global warming has been growing in the Netherlands, according to research from the OECD.

In a country where consensus is a key word, the government has taken a more inclusive approach to climate dissenters. To that end, they have funded Marcel Crok to carry out a sceptical analysis of the IPCC report.

In an effort to build bridges between sceptics and the mainstream they are also funding an initiative called climatedialogue.org which serves as a platform for debate on the science of global warming.

IPCC climate report: humans ‘dominant cause’ of warming – and other articles (BBC)

27 September 2013 Last updated at 09:12 GMT

By Matt McGrathEnvironment correspondent, BBC News, Stockholm

Climate change “threatens our planet, our only home”, warns Thomas Stocker, IPCC co-chair

A landmark report says scientists are 95% certain that humans are the “dominant cause” of global warming since the 1950s.

The report by the UN’s climate panel details the physical evidence behind climate change.

On the ground, in the air, in the oceans, global warming is “unequivocal”, it explained.

It adds that a pause in warming over the past 15 years is too short to reflect long-term trends.

The panel warns that continued emissions of greenhouse gases will cause further warming and changes in all aspects of the climate system.

To contain these changes will require “substantial and sustained reductions of greenhouse gas emissions”.

After a week of intense negotiations in the Swedish capital, the summary for policymakers on the physical science of global warming has finally been released.

The first part of an IPCC trilogy, due over the next 12 months, this dense, 36-page document is considered the most comprehensive statement on our understanding of the mechanics of a warming planet.

It states baldly that, since the 1950s, many of the observed changes in the climate system are “unprecedented over decades to millennia”.

Each of the last three decades has been successively warmer at the Earth’s surface, and warmer than any period since 1850, and probably warmer than any time in the past 1,400 years.

“Our assessment of the science finds that the atmosphere and ocean have warmed, the amount of snow and ice has diminished, the global mean sea level has risen and that concentrations of greenhouse gases have increased,” said Qin Dahe, co-chair of IPCC working group one, who produced the report.

Speaking at a news conference in the Swedish capital, Prof Thomas Stocker, another co-chair, said that climate change “challenges the two primary resources of humans and ecosystems, land and water. In short, it threatens our planet, our only home”.

Since 1950, the report’s authors say, humanity is clearly responsible for more than half of the observed increase in temperatures.

Dr Rajendra Pachauri said he was confident the report would convince the public on global climate change

But a so-called pause in the increase in temperatures in the period since 1998 is downplayed in the report. The scientists point out that this period began with a very hot El Nino year.

“Trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends,” the report says.

Prof Stocker, added: “I’m afraid there is not a lot of public literature that allows us to delve deeper at the required depth of this emerging scientific question.

“For example, there are not sufficient observations of the uptake of heat, particularly into the deep ocean, that would be one of the possible mechanisms to explain this warming hiatus.”

“Likewise we have insufficient data to adequately assess the forcing over the last 10-15 years to establish a relationship between the causes of the warming.”

However, the report does alter a key figure from the 2007 study. The temperature range given for a doubling of CO2 in the atmosphere, called equilibrium climate sensitivity, was 2.0C to 4.5C in that report.

In the latest document, the range has been changed to 1.5C to 4.5C. The scientists say this reflects improved understanding, better temperature records and new estimates for the factors driving up temperatures.

In the summary for policymakers, the scientists say that sea level rise will proceed at a faster rate than we have experienced over the past 40 years. Waters are expected to rise, the document says, by between 26cm (at the low end) and 82cm (at the high end), depending on the greenhouse emissions path this century.

The scientists say ocean warming dominates the increase in energy stored in the climate system, accounting for 90% of energy accumulated between 1971 and 2010.

For the future, the report states that warming is projected to continue under all scenarios. Model simulations indicate that global surface temperature change by the end of the 21st Century is likely to exceed 1.5 degrees Celsius, relative to 1850.

Prof Sir Brian Hoskins, from Imperial College London, told BBC News: “We are performing a very dangerous experiment with our planet, and I don’t want my grandchildren to suffer the consequences of that experiment.”

What is the IPCC?

In its own words, the IPCC is there “to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts”.

The offspring of two UN bodies, the World Meteorological Organization and the United Nations Environment Programme, it has issued four heavyweight assessment reports to date on the state of the climate.

These are commissioned by the governments of 195 countries, essentially the entire world. These reports are critical in informing the climate policies adopted by these governments.

The IPCC itself is a small organisation, run from Geneva with a full time staff of 12. All the scientists who are involved with it do so on a voluntary basis.
