Two dozen scientists, authors, and world and national figures answered two questions: What is your greatest worry about climate change? What gives you hope? Here are some of their answers, condensed for space.

JANE LUBCHENCO, Former administrator, National Oceanic and Atmospheric Administration

I worry about oceans becoming more corrosive, decimating both fisheries and coral reefs. Oceans have already become 30 percent more acidic since the beginning of the Industrial Revolution; if business-as-usual carbon emissions continue, oceans are likely to be 150 percent more acidic by the end of this century. Yikes!

I take heart in knowing that social change can happen very rapidly once a tipping point is reached, that young people are bringing new passion and creativity to the issue, and that climate change is being seen increasingly as the moral issue it is.

TENZIN GYATSO, 14th Dalai Lama of Tibet

The worst possible aspect of climate change is that it will be irreversible and irrevocable. Therefore, there is the urgency to do whatever we can to protect the environment while we can.

When I was young, even I did not really think about the environment, nor did I hear much about it from others. Today, more and more people are trying to take action. We are beginning to look at this planet as our only home, and I am hopeful that this will lead to the generation of a genuine sense of universal responsibility. We can do this.

MICHAEL R. BLOOMBERG, Former mayor of New York City and special United Nations envoy for cities and climate change

Something like 90 percent of the world’s cities are on coasts, and in most places, the most vulnerable people in those cities will feel the worst impacts. We have a responsibility to do something about that. We can’t afford to sit back, cross our fingers and hope for the best.

A tremendous amount of progress is being made by cities all around the world. Cities account for some 70 percent of the emissions that cause climate change, so together they can make a big difference. In New York City back in 2007, we set a goal of reducing our carbon footprint 30 percent by 2030, and we got to a 19 percent reduction in just six years.

Mayors have powers they can use to address climate change immediately. They have control over many of the things that create emissions — like transportation and buildings — and they can invest in infrastructure. They’re not interested in turning the issue into a big political fight. They’re the ones most directly responsible for people’s safety and welfare — and they recognize the dangers of inaction.

JEFFREY SACHS, Director, Earth Institute of Columbia University

The oil industry has lobbied Washington to a state of paralysis, and as is so often true, greed is at the root of the crisis, with the politicians getting in line to feed at the oil trough. The climate deniers are not the real problem. Their transparent propaganda and misdirections are laughable; their scientific ignorance is impossible to miss. The real problem is the cowardice and greed of those who absolutely know better, both in government and industry.

We are living in an age of technological breakthroughs that could transform the world economy to a low-carbon energy system by midcentury. Solar, wind, geothermal, carbon sequestration, safe nuclear energy, and energy efficiency are all part of the mix. The oil industry should cooperate, rather than faking it or dodging it as until now.

BARBARA KINGSOLVER, Novelist; author of the memoir “Animal, Vegetable, Miracle

My fear: Catastrophic extinction. We don’t get to make natural laws. Natural law made us, and it ultimately will unmake us. What makes me very sad is that we’re going to take so many species down with us.

My hope: We in the United States finally seem to be coming to the table after decades of either denial or argument. It seems as if denial as a political strategy has run its course and that we are stepping up to our responsibilities. I hope that’s true.

ALAN I. LESHNER, Chief executive, American Association for the Advancement of Science

Ideology and intuition sometimes appear to be trumping science. So people deny the evidence even as it increases. I fear that the pace at which the public understands that the climate is changing, and puts pressure on the political system, will be too slow.

We are seeing that communicating scientific knowledge has had an effect, and that makes me happy! The deniers have less and less credibility as the public understands the scientific consensus more and more.

NEIL DeGRASSE TYSON, Director, Hayden Planetarium

I find that to worry about things is to invest emotional energy in ways that do not lead to change. Always better to do something about a problem than to worry about it.

What I expect will happen in the coming decades is that beachfront real estate, some of the most expensive in the housing marketplace, will become overrun by storm surges with enough frequency that it will force the wealthiest class (who might have previously been in denial of the phenomenon) to recognize the problem and take action, actions they can take since they are typically captains of industry and are in power and in control.

JERRY BROWN, Governor of California

A huge challenge of climate change lies in the fact that for its solution, countries all over the world must collaborate in ways that are entirely unprecedented.

Each nation-state has to be fully engaged and take decisive steps outside the conventional economic comfort zone. And that requires more statesmanship that is currently in evidence in any of those countries. The mythology of the market and economistic view of life has to be transcended so people understand that a decent and sustainable quality of life requires a very different philosophy than the one that governs contemporary societies.

Here in California, we’re leading the nation in the economic recovery and the creation of jobs, and we are pioneering climate change strategies across a broad front. We have a robust cap-and-trade system. We have a goal of one-third renewable energy in the electricity sector; we’re already at 22 percent. We have the strictest building standards in the world. We have a goal of over a million electric vehicles; we’ve got our first 100,000! We have a certain momentum in California. There are other states where this is also true.

JAMES E. HANSEN, Climate scientist, emeritus director at NASA Goddard Institute for Space Studies

The reason it’s a really dangerous situation is that the climate system does not respond quickly to the forces we apply to it. That means that we have not witnessed the impact of the gases we’ve already added to the atmosphere. We’re waiting for the public to see enough to demand effective government response.

The public doesn’t see that much yet, but there’s more in the pipeline. We are pumping energy into the ocean at a rapid rate; that energy is accumulating, and its biggest impact is going to be on ice shelves. The sea level will go up many meters. That means all coastal cities will be doomed if we stay on fossil fuel business as usual.

The upside is that the only policy that will work is making the price of fossil fuels match their cost. We have an organization determined to focus on exactly that issue: the Citizens Climate Lobby. It’s growing rapidly. Things are changing. But not fast enough.

MARIO J. MOLINA, Co-recipient of the 1995 Nobel Prize for his research on the chemistry of the ozone layer

What worries me most is the irrationality of certain interest groups preventing society from addressing the problem. Republicans in Congress are preventing action on an efficient solution such as a carbon tax.

There is a solution at hand. It doesn’t cost as much as the deniers claim. The Montreal Protocol [on ozone depletion] showed that you could solve such global problems. It would have been much more expensive not to solve it.

ELIZABETH KOLBERT, Author of “The Sixth Extinction: An Unnatural History

For the last 10,000 years or so, the climate’s been relatively stable. But if you start imagining a world with a constantly changing climate, one where, say, rainfall patterns shift dramatically every few decades, then you begin to realize how dependent we all are on that stability. And the world we’re creating is that constantly changing one.

So I worry about just about everything, starting with the basics. There are 7.2 billion people on the planet right now, and we all need to eat.

Hopefulness or a lack of it is really not the issue here. We’ve already caused a lot of damage; there’s a lot of warming that’s in effect baked into the system. We’re capable of causing a great deal more damage, and we’re also capable of limiting that damage. That’s the choice at this point, and we need to face up to that.

J. MARSHALL SHEPHERD, Former president, American Meteorological Society

It bothers me that people think there’s a big debate in science when there isn’t. Being concerned about climate change is not some whim. When I go to the mall or to Walmart, people ask, “Do you really believe in climate change?” That’s like asking, “Do you believe in gravity?” I mean, the science is clear.

What gives me optimism is that many of the people who question the science are of an older generation. The kids get it. When I go to my children’s Scout meetings or when I talk to students on campus, they get beyond the misinformation and politics.

THE REV. MITCHELL C. HESCOX, President, Evangelical Environmental Network

Climate change is the greatest moral challenge of our time because it impacts every single soul in the world. In the conservative Christian world in the United States, we’ve gotten caught up in political partisanship. I’d like to see climate change as a Christian issue and not a partisan issue.

We are the stewards of God’s creation. We believe that the earth’s creation belongs to God and that we are charged to care for it.

When we started this [network] five years ago, we had 15,000 people we regularly communicated with on this issue. Today it approaches 400,000. It means that we’re starting to overcome the partisan divide and the tide is slowly turning.

DIANA H. WALL, Director, School of Global Environmental Sustainability, Colorado State University

What keeps me up, the thing that really drives me nuts, is that the rate of change is so fast. I work in one of the most extreme ecosystems on Earth: the Antarctic Dry Valleys. It is the coldest, windiest, driest place on Earth. We’re seeing warming events and very sunny events there, and this is causing a change in the organisms I study. These species have adapted to the conditions there. We don’t know what the impact will be on them or us.

My students give me hope.

MARTIN REES, Astrophysicist, University of Cambridge

I have a lot more fears than hopes. One aspect that particularly troubles me is that economists tend to underprioritize efforts at mitigation of atmospheric carbon, because the really serious downside of inaction won’t be experienced until the 22nd century and beyond. If action is delayed, it may then be too late to avoid irreversible runaway changes.

We shouldn’t discriminate against our fellow humans on grounds of date of birth. The lifetime welfare of the newborn should rate as highly as that of the already middle-aged. Indeed, many philosophers would assign equal value to the rights of those not yet born.

For them, foreclosing the potentialities of all future generations would be so catastrophic that we should strive to reduce even the tiniest probability that this could happen.

CHRISTINE TODD WHITMAN, Former governor of New Jersey and former administrator, Environmental Protection Agency

What keeps me up at night are people who talk in absolutes. It’s the people who say “humans cause it” or “people have no role in it,” full stop. Science is not exact and the truth is in between. By taking the extreme position, they give an opening to the other side, and then people stop listening.

What gives me hope is that there are signs that the American people are beginning to relate some of the frequent weather extremes to climate.

Since 1980 our economy has grown, our population has grown and our energy use has grown, and yet our overall pollution has gone down. We are perfectly capable of implementing environmental regulation without stopping economic growth.

KATHARINE HAYHOE, Director, Climate Science Center, Texas Tech University

What troubles me as a scientist is the potential for vicious feedbacks within the climate system. The warming that we cause through all the carbon we produce could cause a series of cascading impacts that could lead to a much greater warming. The more carbon we produce, the higher the likelihood of these unpredictable risks.

What makes me hopeful are people. I’ve been working with cities, states and regional transportation councils, and none of them have to be convinced of the reality of this problem. I was sitting next to an assistant city manager for Dallas, a town not known for being green, and she blew me away with her list of amazing things Dallas has done to save energy. People are preparing for change.

MARGARET ATWOOD, Poet and novelist, author of “The Year of the Flood

The most worrisome thing is the potential death of the ocean. If it dies, we die.

What gives me hope is that more and more people are aware of the dangers we face, and many smart people are at work on solutions. Our smart brains got us into this. Let’s see if they can get us out.

FREEMAN J. DYSON, Theoretical physicist, Institute for Advanced Study

What worries me is that many people, including scientists and politicians, believe a whole lot of dogmatic nonsense about climate change. The nonsense says that climate change is a terrible danger and that it is something we could do something about if we wanted to. The whole point is to scare people, and this has been done very successfully.

Climate has always been changing, and climate has always been lousy. It has always been a background to existence that on the whole we’ve learned to cope with pretty well. What I feel happy about is that there are a lot of ordinary people with common sense who don’t believe the nonsense.

MARLENE MOSES, Nauru’s ambassador to the United Nations, chairwoman of the Alliance of Small Island States

When I go home and look at the deteriorating situation there — increased droughts, the ocean washing away the coast — I can’t help but be fearful for what the future may hold for Nauru’s children and grandchildren. How will they adapt? Will the international community be there for them? These are most distressing questions to which I don’t yet have answers.

GLORIA STEINEM, Co-founder and former editor, Ms. Magazine

Thinking about climate change used to give me images of the sun burning down and icebergs melting — horrific, but also impersonal and far away. Now I have intimate fears of storms and floods that drive us off this island of Manhattan, and fires that send thousands fleeing — in other words, just an acceleration of what we’re already seeing.

Like millions of others in public opinion polls, I’m willing to lower my standard of living to help create a turning point. We’re waiting for a practical, coordinated, understandable set of instructions that counters the Kochs, the deniers, the profiteers. Meanwhile, we try to do whatever we can.

Somehow, I find comfort in the idea that the earth is a living organism with a will of its own. The global women’s movement gives me hope because women are trying to take control of their own bodies and reproduction, which is even more basic than production. Everything we know says that when women can decide whether and when to have children, growth slows down to a little over replacement level. And that would be the single biggest long-term relief for the environment.

MARY ROBINSON, Former president of Ireland, former United Nations High Commissioner for human rights

I’m a grandmother with five grandchildren. What will they say about what we did or didn’t do?

It’s Not Genghis Khan’s Mongolia (New York Times)

ULAN BATOR, Mongolia — For all of his victories and skills, Genghis Khan always insisted that the god Tengri — the Eternal Blue Sky — deserved the credit for his triumphant success in uniting the vast Mongol Empire in the early 13th century.

Now 21st-century science may be proving him right. Not long ago, researchers studying ancient tree rings found evidence that the Great Khan rose to power during an exceptionally mild 15-year stretch.

Back-to-back years of plentiful rain and favorable temperatures — known as pluvials, the opposite of droughts — promoted vegetation growth, the researchers believe, and that in turn supported the livestock needed to power an army.

“The Mongol Empire pluvial was quite exceptional in its duration,” said Neil Pederson, an ecologist at Harvard Forest in central Massachusetts. “It was the only one in the past 1,000 years that lasted more than 10 years, so it’s really a singular event.”

These days, Mongolia’s climatic tides have been shifting toward another extreme. A 10-year drought and heat wave from 2000 to 2010, according to the tree ring data, was the most severe the country had had in a millennium.

“I’m more and more convinced that the only way we can understand this 21st-century event is within the context of climate change,” said Amy Hessl, a geographer at West Virginia University. “And the human side of that — combined with a constellation of other factors — is going to be incredible.”

Today, Mongolia is largely herders, not warriors. Sandwiched between Russia and China, it has almost three million people in a vast tract of desert and rolling steppe grassland, punctuated by mountains and forests. Climate continues to significantly shape the lives of Genghis Khan’s descendants, around one-third of whom still practice the seminomadic herding of their ancestors, moving their house — traditionally, a dome-shaped tent called a ger — with the seasons.

While televisions and solar panels are a common sight in modern gers, herders still rely on thousands of years of collective knowledge to thrive in the harsh Mongolian environment, where the temperature regularly dips below minus 15 degrees Fahrenheit in winter. Yet the predictable ebb and flow of warmth and cold, rain and snow, has begun to falter in recent years.

“I don’t know why the weather has become unusual, but I’m very worried about it,” said Urgamaltsetsg Suvita, 47, a herder in the Gobi Desert. Summer is hotter and drier and plagued by sandstorms, she said, and winter brings too much snow or too little.

In 2010, an extreme snowstorm killed her flock of livestock — nearly 1,000 animals, including horses, sheep and goats. “Winter is no longer winter,” she said.

Like much of the world, Mongolia is already experiencing the effects of climate change. The country’s average annual temperature has risen more than 3.8 degrees Fahrenheit since 1940; paradoxically, winter months have grown colder over the past 20 years. Streams and lakes have begun to dry up, and fires frequently blaze across millions of acres of steppe and forest.

“The steppe ecosystem is burning and burning and burning,” said Oyunsanaa Byambasuren, a lecturer in forestry at the National University of Mongolia. “But we really don’t have enough specialists or professionals dealing with those issues.”

Dzuds — extreme winter events that cause mass livestock die-offs — also seem to be increasing in frequency and intensity. From 1999 to 2002, a succession of winter dzuds followed by summer droughts killed 30 percentof all livestock in Mongolia, and a 2010 dzud claimed 8.8 million livestock — losses equivalent to 4.4 percent of the country’s economic output.

“Wealth in much of Mongolia is measured in animals,” said Nicole Davi, a research scientist at Lamont-Doherty Earth Observatory and at William Paterson University. “If you lose all of your animals, you lose everything.”

Ayush Ish, 69, has lived in the Gobi Desert all her life. She and her husband lost their flock of goats and sheep in the 2002 dzud and drought, then slowly rebuilt it with the help of 50 animals allocated by the government. But when the 2010 dzud struck, all but 20 died. Around the same time, her husband died as well.

“I don’t know if it will happen again,” she said, tears running down her cheeks. “I can only hope that we’re entering a good period now.”

Like many rural Mongolians who follow a shamanistic belief system, Ms. Ish says that mining — which has recently become widespread around the country — is to blame for the changing weather patterns. Troy Sternberg, a geographer at the University of Oxford, said that “under the Mongolian belief system, the earth and sky are connected, so if you take gold out of the ground, you’re disrupting the natural rhythms of weather and climate.”

Whether or not that is true, the rise of mining — along with overgrazing by herders chasing the cashmere market — has led to wide desertification. Some studies indicate that 70 percent of Mongolia’s grasslands are degraded.

Taken together, these patterns bode ominously for the herders’ way of life. A team of Mongolian and international experts warned in a 2009 report that such trends “may lead to the end of the Mongolian traditional way of animal husbandry as we know it, that at onetime was the very core of the entire nomadic civilization.”

Some herders have already reached that breaking point. After the 1999 to 2002 dzuds alone, 180,000 people moved to the capital, Ulan Bator, in search of a better life. “The movement from a rural, agrarian life to an urban industrial one is not necessarily a bad thing if people are interested in doing other things that are tied to a more diverse economy,” said Maria Fernandez-Gimenez, an ecologist at Colorado State University. “But opportunities and services have to exist to enable that.”

Those who reach the capital usually settle in the ger district, a sprawling, makeshift neighborhood that encircles the city and creeps into the surrounding valleys. Although the skyscrapers of downtown are in eyesight, basic services are luxuries. Families must trek up to a mile to collect water from communal wells, and in winter, they burn coal and garbage to keep warm, helping to make Ulan Bator one of the world’s most polluted cities.

Khishigee Shuurai, 36, moved from western Mongolia to the capital around 15 years ago. In 2002, after losing their flock, her parents joined her in the city. Then her father died of a heart attack. Before that, she said, he frequently expressed a longing to return to the countryside.

For many, however, life here is preferable to the uncertainty and harshness of nomadic herding. Ms. Shuurai, a school custodian and mother of four, does not share her father’s regrets.

She and her husband, a construction worker, have jobs, and they recently got electricity in their ger. Her 7-year-old daughter was honored as the top student in her class, and her 12-year-old son wants to become an engineer.

“There’s many reasons to stay,” she said. “I don’t want to go back.”

5 razões para assistir à Cúpula do Clima de Nova York (Portal do Meio Ambiente)

PUBLICADO 18 SETEMBRO 2014

por Jennifer Morgan*

No próximo dia 23 de setembro, chefes de estado e líderes do sistema financeiro, de empresas e da sociedade civil se reunirão em Nova York na Cúpula do Clima das Nações Unidas de 2014. A reunião será um marco importante no caminho de enfrentamento da crise climática. O Secretário-geral da ONU, Ban Ki-moon, convocou a Cúpula de alto nível para reengajar os líderes mundiais e estimular a ação pelo clima nos níveis nacionais e internacional.

Dezenas de milhares de cidadãos interessados estão aproveitando a oportunidade para organizar a maior marcha pelo clima da história. Durante a semana da Cúpula centenas de organizações organizarão palestras, exibições de cinema documental e outros encontros para apresentar evidências esmagadoras das consequências das alterações climáticas e soluções custo-efetivas para resolver o problema. Novos estudos científicos como a Avaliação Nacional do Clima dos EUA e os últimos relatórios do IPCC iluminaram os riscos de poluição da atmosfera pelo carbono, enquanto novas análises econômicas, incluindo próximo relatório Nova Economia do Clima, do World Resources Institute, devem dissipar a noção de que a ação pelo clima desacelerará o crescimento econômico.

No entanto, esta não é a primeira vez que os governos são convocados para combater as mudanças climáticas. Então, por que vale a pena assistir a esta Cúpula? Aqui estão os porquês:

1) É a primeira vez em cinco anos na qual chefes de estado se reunirão para enfrentar a mudança climática

Esta será a primeira vez em cinco anos – desde as negociações de Copenhague de 2009 – que tantos líderes mundiais se reunirão para discutir a mudança climática. O Secretário-Geral Ban Ki-moon chamou a Cúpula para dar o pontapé inicial de um período de 15 meses de intenso engajamento e negociação pelo clima como tentativa de obter um acordo global em dezembro de 2015. Criar uma boa dinâmica em Nova York será extremamente importante para alcançar esse objetivo.

2) Obama e Xi estarão lá**

Tanto o presidente dos EUA, Barack Obama quanto o presidente chinês, Xi Jinping, líderes dos dois países que mais emitem gases de efeito estufa, participarão da cúpula. Se medidas substantivas de redução das emissões devem ser implantadas, tanto os EUA quanto a China deverão se envolver completamente. É encorajador que os dois países já estejam colaborando em projetos de energia limpa nos níveis de pesquisa, de governo e empresarial por meio de iniciativas como os Centro de Pesquisa de Energia Limpa EUA-China (CERC). Em julho os dois países revelaram oito novos acordos de parceria climática. A presença desses chefes de estado na Cúpula oferece uma oportunidade de continuidade da cooperação.

3) Novas vozes que clamam por maior ação

A maioria dos atuais líderes ainda não estava no poder em 2009, quando da Cúpula de Copenhague. Muitos destes falam abertamente sobre a ameaça que a mudança climática representa para seus países, bem como sobre as oportunidades econômicas que se abrem com a perspectiva de economia de baixo carbono. Estas novas vozes vêm de países de renda média como Chile, Colômbia, Costa Rica e Indonésia onde os governos estão implantando políticas climáticas ambiciosas ou manifestam vontade de fazê-lo. Suas novas visões devem moldar as discussões da cúpula de alto nível.

Também se espera que os países mais pobres apresentem seus desafios e suas contribuições para a solução do problema.

4) Novos compromissos de países, cidades e do setor privado

A Cúpula de um dia será um fórum para a troca de iniciativas entre os países. Durante a manhã acontecerão três sessões simultâneas nas quais os países devem anunciar suas medidas de combate às mudanças climáticas. Os anúncios provavelmente variarão de compromissos de capitalização do Fundo Verde para o Clima, como a contribuição de US$ 1 bilhão feita recentemente pela Alemanha como ajuda aos demais países para sua preparação para os impactos do clima e busca de caminhos de baixo carbono, até ações internas como de alteração de matrizes energéticas desde o carvão às energias renováveis de grande escala.

Os líderes mundiais também podem usar a reunião para se comprometerem a apresentar um rascunho de seus planos climáticos pós-2020 até o mês de março de 2015 (processo conhecido no jargão das negociações como “contribuições intencionais nacionais determinadas” ou INDCs na sigla em inglês) – de modo a incentivar seus colegas a também fazê-lo. O respeito a esse prazo dará aos ‘stakeholders’ nacionais e internacionais a oportunidade de responder e sugerir melhorias antes dos países apresentarem suas propostas definitivas nove meses depois, em Paris.

Finalmente, o encontro oferece uma plataforma para a apresentação de novas e significativas ideias pelos líderes do setor privado e das cidades. Prepare-se para conhecer novos esforços privados e/ou públicos em matéria de energia, cidades de baixo carbono, restauração florestal, transporte, agricultura, finanças e resiliência. Estas novas iniciativas complementarão as ações nacionais envolvendo todos os níveis da sociedade no esforço global para o enfrentamento do problema.

5) A transição global para a energia limpa está remodelando a paisagem da política

A rápida adoção de energias renováveis nos últimos anos mudou o que era considerado viável há apenas cinco anos. Os custos de produção da energia solar caíram 80% e a energia eólica nunca foi tão acessível. Em outubro passado, a Dinamarca produziu mais energia a partir dos ventos do que o total consumido pelo país. A China estabeleceu metas agressivas para energias renováveis para os anos de 2015, 2017 e 2020. Mais e mais empresas elétricas norte americanas estão descobrindo que o vento e o Sol oferecem a forma mais barata para adicionar capacidade de geração adicional. E cerca de 100 países em desenvolvimento têm agora estabelecidas políticas para energia renováveis. O panorama energético em mudança e os fortes benefícios sociais e econômicos da transição para a energia limpa dão argumentos fortes aos líderes dos países e das empresas pela liderança climática.

Uma chance para que os líderes mundiais se comprometam pela ação climática

A Cúpula será um prenúncio para o compromisso dos chefes de estado quanto ao enfrentamento da crise climática no período que leva a Paris e além. Fortes e claros compromissos elevariam a mudança climática na agenda global e preparariam o terreno para o progresso nacional e internacional.

Durante uma reunião de alto nível em Abu Dhabi em maio deste ano, Ban Ki-moon exortou os participantes a “capacitar e motivar os seus líderes nacionais para que tragam anúncios ousados à Cúpula do Clima de setembro… A corrida começou. É hora de liderar”. Em poucas semanas veremos se os líderes estão à altura do desafio.

The ‘Wall Street Journal’ Parade of Climate Lies (Huff Post)

Posted: 09/06/2014 8:21 am EDT Updated: 09/07/2014 10:59 pm EDT

RUPERT MURDOCH

That Rupert Murdoch governs over a criminal media empire has been made clear enough in the UK courts in recent years. That the Wall Street Journal op-ed pages, the latest victim of Murdoch’s lawless greed, are little more than naked propaganda is perhaps less appreciated. The Journal runs one absurd op-ed after another purporting to unmask climate change science, but only succeeds in unmasking the crudeness and ignorance of Murdoch’s henchmen. Yesterday’s (September 5) op-edby Matt Ridley is a case in point.

Ridley’s “smoking gun” is a paper last week in Science Magazine by two scientists Xianyao Chen and Ka-Kit Tung, which Ridley somehow believes refutes all previous climate science. Ridley quotes a sentence fragment from the press release suggesting that roughly half of the global warming in the last three decades of the past century (1970-2000) was due to global warming and half to a natural Atlantic Ocean cycle. He then states that “the man-made warming of the past 20 years has been so feeble that a shifting current in one ocean was enough to wipe it out altogether,” and “That to put the icing on the case of good news, Xianyao Chen and Ka-Kit Tung think the Atlantic Ocean may continue to prevent any warming for the next two decades.”

The Wall Street Journal editors don’t give a hoot about the nonsense they publish if it serves their cause of fighting measures to limit human-induced climate change. If they had simply gone online to read the actual paper, they would have found that the paper’s conclusions are the very opposite of Ridley’s.

First, the paper makes perfectly clear that the Earth is warming in line with standard climate science, and that the Earth’s warming is unabated in recent years. In the scientific lingo of the paper (it’s very first line, so Ridley didn’t have far to read!), “Increasing anthropogenic greenhouse-gas-emissions perturb Earth’s radiative equilibrium, leading to a persistent imbalance at the top of the atmosphere (TOA) despite some long-wave radiative adjustment.” In short, we humans are filling the atmosphere with carbon dioxide from fossil-fuel use, and we are warming the planet.

Second, the total warming is distributed between the land and ocean surface on the one hand and the ocean deep water on the other. The total rise of ocean heat content has continued unabated, while the proportion of heat absorbed at the surface and in the deeper ocean varies over time. Again, in the scientific lingo of the paper, “[T]his forced total OHC [ocean heat content] should be increasing monotonically over longer periods even through the current period of slowed warming. In fact, that expectation is verified by observation …”. In other words, the ocean has continued to warm in line with predictions of just such a phenomenon seen in climate models.

Third, it is the “vertical distribution” of the warming, between the surface and deep water, which affects the warming observed on land and at the sea surface. The point of the paper is that the allocation of the warming vertically varies over time, sometimes warming the surface rapidly, other times warming the deeper ocean to a great extent and the surface water less rapidly. According to the paper, the period of the late 20th century was a period in which the surface was warmed relative to the deeper ocean. The period since 2000 is the opposite, with more warming of the deeper ocean. How do the scientists know? They measure the ocean temperature at varying depths with a sophisticated system of “Argo profiling floats,” which periodically dive into the ocean depths to take temperature readings and resurface to transmit them to the data centers.

So, what is Ridley’s “smoking gun” when you strip away his absurd version of the paper? It goes like this. The Earth is continuing to warm just as greenhouse gas theory holds. The warming heats the land and the ocean. The ocean distributes some of the warming to the surface waters and some to the deeper waters, depending on the complex circulation of ocean waters. The shares of warming of the surface and deeper ocean vary over time, in fluctuations that can last a few years or a few decades.

If the surface warming is somewhat less in recent years than in the last part of the 20th century, is that reason for complacency? Hardly. The warming is continuing, and the consequences of our current trajectory will be devastating unless greenhouse gas emissions (mainly carbon dioxide) are stopped during this century. As Chen and Tung conclude in their Science paper, “When the internal variability [of the ocean] that is responsible for the current hiatus [in warming] switches sign, as it inevitably will, another episode of accelerated global warming should ensue.”

Mr. Murdoch, and the Wall Street Journal, can it be any clearer than this?

The Wall Street Journal downplays global warming risks once again (The Guardian)

Monday 22 September 2014 14.00 BST

The periodical follows the Murdoch media pattern of sowing doubt about climate change threats

As has become the norm for media outlets owned by Rupert Murdoch, just before a half million people participated in the People’s Climate Marcharound the world, The Wall Street Journal published an opinion piece downplaying the risks and threats posed by human-caused global warming. The editorial was written by Steven Koonin, a respected computational physicist who claims to have engaged in “Detailed technical discussions during the past year with leading climate scientists,” but who is himself not a climate scientist.

Koonin did admit that the climate is changing and humans are largely responsible, and noted,

There is well-justified prudence in accelerating the development of low-emissions technologies and in cost-effective energy-efficiency measures.

This is a step in the right direction. Unfortunately, Koonin’s editorial focused almost exclusively on the remaining uncertainties in climate science. Ironically, he stated,

Any serious discussion of the changing climate must begin by acknowledging not only the scientific certainties but also the uncertainties, especially in projecting the future.

But Koonin himself got the certainties wrong. For example, we know that humans are the main cause of the current climate change, responsible for about 100% of the global warming since 1950. However, Koonin’s editorial claimed,

The impact today of human activity appears to be comparable to the intrinsic, natural variability of the climate system itself.

This is simply incorrect. As climate scientist Michael Mann told Climate Science Watch in their thorough response to Koonin’s piece,

The fact is that the actual peer-reviewed scientific research shows that (a) the rate of warming over the past century is unprecedented as far back as the 20,000 years paleoclimate scientists are able to extend the record and (b) that warming can ONLY be explained by human influences.

Indeed, it is the RATE of warming that presents such risk to human civilization and our environment.

Climate scientists Michael Oppenheimer and Kevin Trenberth also took issue with Koonin’s assertion about the impact of human activity, saying,

Warming is well beyond natural climate variability and projected rates of change are potentially faster than ecosystems, farmers and societies can adapt to without major disruptions. Many details remain to be settled, and weather and natural variability will always mask some effects, especially regionally. But economic analysis of these risks supports substantial action beyond “no regrets” strategies. To argue otherwise as Koonin does is to ignore decades of research results.

Koonin primarily focused on the uncertainty in the specific impacts of continued rapid global warming. However, he glossed over the fact that those uncertainties range from generally bad impacts to potentially catastrophic impacts. Even in a best case scenario, climate science research indicates that we anticipate experiencing widespread coral mortality, hundreds of millions of people at risk of increased water stress, more damage from droughts and heat waves and floods, up to 30% of global species at risk for extinction, and declined global food production, for example.

Those are the anticipated impacts if we limit global warming to not much above 2°C warming as compared to pre-industrial levels. Accomplishing that would require intensive efforts to reduce human greenhouse gas emissions, and if we fail, the consequence will be far worse.

The good news is that slowing global warming can be accomplished with minimal economic impact. In fact, economic research consistently shows that reducing greenhouse gas emissions, if done right, is far cheaper than paying for the damages caused by unabated climate change. For example, a revenue-neutral carbon tax could create jobs and grow the economy. Two recent studies by the New Climate Economy Project and the International Monetary Fund likewise found that reducing carbon pollution could grow the economy, as summarized by The Guardian.

As Koonin noted in his piece, risk management is key in determining how to respond to the threats posed by climate change. On the one hand, we have a threat to the entire global climate on which every species on Earth relies, which humans are in the process of destabilizing at a rate more rapid than many species can adapt.

On the other hand, we have concerns about the impacts of climate policy on the economy. However, numerous studies have found that if done right, those policies can grow the economy, and will certainly be cheaper than paying for the damages of unabated climate change.

While uncertainties remain about whether the impacts of climate change will be bad, catastrophic, or somewhere in between, that’s precisely the kind of scenario in which uncertainty is not our friend. When faced with a risk to something so important, humans are usually smart enough to take action to manage that risk. For example, we buy home insurance, we wear seat belts, and fewer people now smoke than in previous generations who were unaware of the associated risks.

It’s critical to grasp not just that there are uncertainties about the impacts of climate change, but what those uncertainties tell us about the range of potential outcomes. It’s easy to simply say “the impacts are uncertain,” but when those uncertainties range from bad to catastrophic, taking action to mitigate the threat is a no-brainer. Additionally, larger uncertainty means that we can’t rule out the most catastrophic potential impacts, and actually makes the case for taking action stronger, as a study published earlier this year showed.

The bottom line is that while there are and always will be uncertainties in climate science that require further research, it’s already been several decades since we’ve understood climate change well enough to justify taking serious action to solve the problem. The longer we wait, the costlier those actions become, and the worse the impacts of human-caused global warming will be. The hundreds of thousands of people who marched yesterday understand that, but the Murdoch media hasn’t caught up yet.

Global Warming’s Terrifying New Math (Rolling Stone)

Three simple numbers that add up to global catastrophe – and that make clear who the real enemy is

If the pictures of those towering wildfires in Colorado haven’t convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States. That followed the warmest May on record for the Northern Hemisphere – the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe.

Meteorologists reported that this spring was the warmest ever recorded for our nation – in fact, it crushed the old record by so much that it represented the “largest temperature departure from average of any season on record.” The same week, Saudi authorities reported that it had rained in Mecca despite a temperature of 109 degrees, the hottest downpour in the planet’s history.

Not that our leaders seemed to notice. Last month the world’s nations, meeting in Rio for the 20th-anniversary reprise of a massive 1992 environmental summit, accomplished nothing. Unlike George H.W. Bush, who flew in for the first conclave, Barack Obama didn’t even attend. It was “a ghost of the glad, confident meeting 20 years ago,” the British journalist George Monbiot wrote; no one paid it much attention, footsteps echoing through the halls “once thronged by multitudes.” Since I wrote one of the first books for a general audience about global warming way back in 1989, and since I’ve spent the intervening decades working ineffectively to slow that warming, I can say with some confidence that we’re losing the fight, badly and quickly – losing it because, most of all, we remain in denial about the peril that human civilization is in.

When we think about global warming at all, the arguments tend to be ideological, theological and economic. But to grasp the seriousness of our predicament, you just need to do a little math. For the past year, an easy and powerful bit of arithmetical analysis first published by financial analysts in the U.K. has been making the rounds of environmental conferences and journals, but it hasn’t yet broken through to the larger public. This analysis upends most of the conventional political thinking about climate change. And it allows us to understand our precarious – our almost-but-not-quite-finally hopeless – position with three simple numbers.

The First Number: 2° Celsius

If the movie had ended in Hollywood fashion, the Copenhagen climate conference in 2009 would have marked the culmination of the global fight to slow a changing climate. The world’s nations had gathered in the December gloom of the Danish capital for what a leading climate economist, Sir Nicholas Stern of Britain, called the “most important gathering since the Second World War, given what is at stake.” As Danish energy minister Connie Hedegaard, who presided over the conference, declared at the time: “This is our chance. If we miss it, it could take years before we get a new and better one. If ever.”

In the event, of course, we missed it. Copenhagen failed spectacularly. Neither China nor the United States, which between them are responsible for 40 percent of global carbon emissions, was prepared to offer dramatic concessions, and so the conference drifted aimlessly for two weeks until world leaders jetted in for the final day. Amid considerable chaos, President Obama took the lead in drafting a face-saving “Copenhagen Accord” that fooled very few. Its purely voluntary agreements committed no one to anything, and even if countries signaled their intentions to cut carbon emissions, there was no enforcement mechanism. “Copenhagen is a crime scene tonight,” an angry Greenpeace official declared, “with the guilty men and women fleeing to the airport.” Headline writers were equally brutal: COPENHAGEN: THE MUNICH OF OUR TIMES? asked one.

The accord did contain one important number, however. In Paragraph 1, it formally recognized “the scientific view that the increase in global temperature should be below two degrees Celsius.” And in the very next paragraph, it declared that “we agree that deep cuts in global emissions are required… so as to hold the increase in global temperature below two degrees Celsius.” By insisting on two degrees – about 3.6 degrees Fahrenheit – the accord ratified positions taken earlier in 2009 by the G8, and the so-called Major Economies Forum. It was as conventional as conventional wisdom gets. The number first gained prominence, in fact, at a 1995 climate conference chaired by Angela Merkel, then the German minister of the environment and now the center-right chancellor of the nation.

Some context: So far, we’ve raised the average temperature of the planet just under 0.8 degrees Celsius, and that has caused far more damage than most scientists expected. (A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.) Given those impacts, in fact, many scientists have come to think that two degrees is far too lenient a target. “Any number much above one degree involves a gamble,” writes Kerry Emanuel of MIT, a leading authority on hurricanes, “and the odds become less and less favorable as the temperature goes up.” Thomas Lovejoy, once the World Bank’s chief biodiversity adviser, puts it like this: “If we’re seeing what we’re seeing today at 0.8 degrees Celsius, two degrees is simply too much.” NASA scientist James Hansen, the planet’s most prominent climatologist, is even blunter: “The target that has been talked about in international negotiations for two degrees of warming is actually a prescription for long-term disaster.” At the Copenhagen summit, a spokesman for small island nations warned that many would not survive a two-degree rise: “Some countries will flat-out disappear.” When delegates from developing nations were warned that two degrees would represent a “suicide pact” for drought-stricken Africa, many of them started chanting, “One degree, one Africa.”

Despite such well-founded misgivings, political realism bested scientific data, and the world settled on the two-degree target – indeed, it’s fair to say that it’s the only thing about climate change the world has settled on. All told, 167 countries responsible for more than 87 percent of the world’s carbon emissions have signed on to the Copenhagen Accord, endorsing the two-degree target. Only a few dozen countries have rejected it, including Kuwait, Nicaragua and Venezuela. Even the United Arab Emirates, which makes most of its money exporting oil and gas, signed on. The official position of planet Earth at the moment is that we can’t raise the temperature more than two degrees Celsius – it’s become the bottomest of bottom lines. Two degrees.

The Second Number: 565 Gigatons

Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere by midcentury and still have some reasonable hope of staying below two degrees. (“Reasonable,” in this case, means four chances in five, or somewhat worse odds than playing Russian roulette with a six-shooter.)

This idea of a global “carbon budget” emerged about a decade ago, as scientists began to calculate how much oil, coal and gas could still safely be burned. Since we’ve increased the Earth’s temperature by 0.8 degrees so far, we’re currently less than halfway to the target. But, in fact, computer models calculate that even if we stopped increasing CO2 now, the temperature would likely still rise another 0.8 degrees, as previously released carbon continues to overheat the atmosphere. That means we’re already three-quarters of the way to the two-degree target.

How good are these numbers? No one is insisting that they’re exact, but few dispute that they’re generally right. The 565-gigaton figure was derived from one of the most sophisticated computer-simulation models that have been built by climate scientists around the world over the past few decades. And the number is being further confirmed by the latest climate-simulation models currently being finalized in advance of the next report by the Intergovernmental Panel on Climate Change. “Looking at them as they come in, they hardly differ at all,” says Tom Wigley, an Australian climatologist at the National Center for Atmospheric Research. “There’s maybe 40 models in the data set now, compared with 20 before. But so far the numbers are pretty much the same. We’re just fine-tuning things. I don’t think much has changed over the last decade.” William Collins, a senior climate scientist at the Lawrence Berkeley National Laboratory, agrees. “I think the results of this round of simulations will be quite similar,” he says. “We’re not getting any free lunch from additional understanding of the climate system.”

We’re not getting any free lunch from the world’s economies, either. With only a single year’s lull in 2009 at the height of the financial crisis, we’ve continued to pour record amounts of carbon into the atmosphere, year after year. In late May, the International Energy Agency published its latest figures – CO2 emissions last year rose to 31.6 gigatons, up 3.2 percent from the year before. America had a warm winter and converted more coal-fired power plants to natural gas, so its emissions fell slightly; China kept booming, so its carbon output (which recently surpassed the U.S.) rose 9.3 percent; the Japanese shut down their fleet of nukes post-Fukushima, so their emissions edged up 2.4 percent. “There have been efforts to use more renewable energy and improve energy efficiency,” said Corinne Le Quéré, who runs England’s Tyndall Centre for Climate Change Research. “But what this shows is that so far the effects have been marginal.” In fact, study after study predicts that carbon emissions will keep growing by roughly three percent a year – and at that rate, we’ll blow through our 565-gigaton allowance in 16 years, around the time today’s preschoolers will be graduating from high school. “The new data provide further evidence that the door to a two-degree trajectory is about to close,” said Fatih Birol, the IEA’s chief economist. In fact, he continued, “When I look at this data, the trend is perfectly in line with a temperature increase of about six degrees.” That’s almost 11 degrees Fahrenheit, which would create a planet straight out of science fiction.

So, new data in hand, everyone at the Rio conference renewed their ritual calls for serious international action to move us back to a two-degree trajectory. The charade will continue in November, when the next Conference of the Parties (COP) of the U.N. Framework Convention on Climate Change convenes in Qatar. This will be COP 18 – COP 1 was held in Berlin in 1995, and since then the process has accomplished essentially nothing. Even scientists, who are notoriously reluctant to speak out, are slowly overcoming their natural preference to simply provide data. “The message has been consistent for close to 30 years now,” Collins says with a wry laugh, “and we have the instrumentation and the computer power required to present the evidence in detail. If we choose to continue on our present course of action, it should be done with a full evaluation of the evidence the scientific community has presented.” He pauses, suddenly conscious of being on the record. “I should say, a fuller evaluation of the evidence.”

So far, though, such calls have had little effect. We’re in the same position we’ve been in for a quarter-century: scientific warning followed by political inaction. Among scientists speaking off the record, disgusted candor is the rule. One senior scientist told me, “You know those new cigarette packs, where governments make them put a picture of someone with a hole in their throats? Gas pumps should have something like that.”

The Third Number: 2,795 Gigatons

This number is the scariest of all – one that, for the first time, meshes the political and scientific dimensions of our dilemma. It was highlighted last summer by the Carbon Tracker Initiative, a team of London financial analysts and environmentalists who published a report in an effort to educate investors about the possible risks that climate change poses to their stock portfolios. The number describes the amount of carbon already contained in the proven coal and oil and gas reserves of the fossil-fuel companies, and the countries (think Venezuela or Kuwait) that act like fossil-fuel companies. In short, it’s the fossil fuel we’re currently planning to burn. And the key point is that this new number – 2,795 – is higher than 565. Five times higher.

The Carbon Tracker Initiative – led by James Leaton, an environmentalist who served as an adviser at the accounting giant PricewaterhouseCoopers – combed through proprietary databases to figure out how much oil, gas and coal the world’s major energy companies hold in reserve. The numbers aren’t perfect – they don’t fully reflect the recent surge in unconventional energy sources like shale gas, and they don’t accurately reflect coal reserves, which are subject to less stringent reporting requirements than oil and gas. But for the biggest companies, the figures are quite exact: If you burned everything in the inventories of Russia’s Lukoil and America’s ExxonMobil, for instance, which lead the list of oil and gas companies, each would release more than 40 gigatons of carbon dioxide into the atmosphere.

Which is exactly why this new number, 2,795 gigatons, is such a big deal. Think of two degrees Celsius as the legal drinking limit – equivalent to the 0.08 blood-alcohol level below which you might get away with driving home. The 565 gigatons is how many drinks you could have and still stay below that limit – the six beers, say, you might consume in an evening. And the 2,795 gigatons? That’s the three 12-packs the fossil-fuel industry has on the table, already opened and ready to pour.

We have five times as much oil and coal and gas on the books as climate scientists think is safe to burn. We’d have to keep 80 percent of those reserves locked away underground to avoid that fate. Before we knew those numbers, our fate had been likely. Now, barring some massive intervention, it seems certain.

Yes, this coal and gas and oil is still technically in the soil. But it’s already economically aboveground – it’s figured into share prices, companies are borrowing money against it, nations are basing their budgets on the presumed returns from their patrimony. It explains why the big fossil-fuel companies have fought so hard to prevent the regulation of carbon dioxide – those reserves are their primary asset, the holding that gives their companies their value. It’s why they’ve worked so hard these past years to figure out how to unlock the oil in Canada’s tar sands, or how to drill miles beneath the sea, or how to frack the Appalachians.

If you told Exxon or Lukoil that, in order to avoid wrecking the climate, they couldn’t pump out their reserves, the value of their companies would plummet. John Fullerton, a former managing director at JP Morgan who now runs the Capital Institute, calculates that at today’s market value, those 2,795 gigatons of carbon emissions are worth about $27 trillion. Which is to say, if you paid attention to the scientists and kept 80 percent of it underground, you’d be writing off $20 trillion in assets. The numbers aren’t exact, of course, but that carbon bubble makes the housing bubble look small by comparison. It won’t necessarily burst – we might well burn all that carbon, in which case investors will do fine. But if we do, the planet will crater. You can have a healthy fossil-fuel balance sheet, or a relatively healthy planet – but now that we know the numbers, it looks like you can’t have both. Do the math: 2,795 is five times 565. That’s how the story ends.

So far, as I said at the start, environmental efforts to tackle global warming have failed. The planet’s emissions of carbon dioxide continue to soar, especially as developing countries emulate (and supplant) the industries of the West. Even in rich countries, small reductions in emissions offer no sign of the real break with the status quo we’d need to upend the iron logic of these three numbers. Germany is one of the only big countries that has actually tried hard to change its energy mix; on one sunny Saturday in late May, that northern-latitude nation generated nearly half its power from solar panels within its borders. That’s a small miracle – and it demonstrates that we have the technology to solve our problems. But we lack the will. So far, Germany’s the exception; the rule is ever more carbon.

This record of failure means we know a lot about what strategies don’t work. Green groups, for instance, have spent a lot of time trying to change individual lifestyles: the iconic twisty light bulb has been installed by the millions, but so have a new generation of energy-sucking flatscreen TVs. Most of us are fundamentally ambivalent about going green: We like cheap flights to warm places, and we’re certainly not going to give them up if everyone else is still taking them. Since all of us are in some way the beneficiaries of cheap fossil fuel, tackling climate change has been like trying to build a movement against yourself – it’s as if the gay-rights movement had to be constructed entirely from evangelical preachers, or the abolition movement from slaveholders.

People perceive – correctly – that their individual actions will not make a decisive difference in the atmospheric concentration of CO2; by 2010, a poll found that “while recycling is widespread in America and 73 percent of those polled are paying bills online in order to save paper,” only four percent had reduced their utility use and only three percent had purchased hybrid cars. Given a hundred years, you could conceivably change lifestyles enough to matter – but time is precisely what we lack.

A more efficient method, of course, would be to work through the political system, and environmentalists have tried that, too, with the same limited success. They’ve patiently lobbied leaders, trying to convince them of our peril and assuming that politicians would heed the warnings. Sometimes it has seemed to work. Barack Obama, for instance, campaigned more aggressively about climate change than any president before him – the night he won the nomination, he told supporters that his election would mark the moment “the rise of the oceans began to slow and the planet began to heal.” And he has achieved one significant change: a steady increase in the fuel efficiency mandated for automobiles. It’s the kind of measure, adopted a quarter-century ago, that would have helped enormously. But in light of the numbers I’ve just described, it’s obviously a very small start indeed.

At this point, effective action would require actually keeping most of the carbon the fossil-fuel industry wants to burn safely in the soil, not just changing slightly the speed at which it’s burned. And there the president, apparently haunted by the still-echoing cry of “Drill, baby, drill,” has gone out of his way to frack and mine. His secretary of interior, for instance, opened up a huge swath of the Powder River Basin in Wyoming for coal extraction: The total basin contains some 67.5 gigatons worth of carbon (or more than 10 percent of the available atmospheric space). He’s doing the same thing with Arctic and offshore drilling; in fact, as he explained on the stump in March, “You have my word that we will keep drilling everywhere we can… That’s a commitment that I make.” The next day, in a yard full of oil pipe in Cushing, Oklahoma, the president promised to work on wind and solar energy but, at the same time, to speed up fossil-fuel development: “Producing more oil and gas here at home has been, and will continue to be, a critical part of an all-of-the-above energy strategy.” That is, he’s committed to finding even more stock to add to the 2,795-gigaton inventory of unburned carbon.

Sometimes the irony is almost Borat-scale obvious: In early June, Secretary of State Hillary Clinton traveled on a Norwegian research trawler to see firsthand the growing damage from climate change. “Many of the predictions about warming in the Arctic are being surpassed by the actual data,” she said, describing the sight as “sobering.” But the discussions she traveled to Scandinavia to have with other foreign ministers were mostly about how to make sure Western nations get their share of the estimated $9 trillion in oil (that’s more than 90 billion barrels, or 37 gigatons of carbon) that will become accessible as the Arctic ice melts. Last month, the Obama administration indicated that it would give Shell permission to start drilling in sections of the Arctic.

Almost every government with deposits of hydrocarbons straddles the same divide. Canada, for instance, is a liberal democracy renowned for its internationalism – no wonder, then, that it signed on to the Kyoto treaty, promising to cut its carbon emissions substantially by 2012. But the rising price of oil suddenly made the tar sands of Alberta economically attractive – and since, as NASA climatologist James Hansen pointed out in May, they contain as much as 240 gigatons of carbon (or almost half of the available space if we take the 565 limit seriously), that meant Canada’s commitment to Kyoto was nonsense. In December, the Canadian government withdrew from the treaty before it faced fines for failing to meet its commitments.

The same kind of hypocrisy applies across the ideological board: In his speech to the Copenhagen conference, Venezuela’s Hugo Chavez quoted Rosa Luxemburg, Jean-Jacques Rousseau and “Christ the Redeemer,” insisting that “climate change is undoubtedly the most devastating environmental problem of this century.” But the next spring, in the Simon Bolivar Hall of the state-run oil company, he signed an agreement with a consortium of international players to develop the vast Orinoco tar sands as “the most significant engine for a comprehensive development of the entire territory and Venezuelan population.” The Orinoco deposits are larger than Alberta’s – taken together, they’d fill up the whole available atmospheric space.

So: the paths we have tried to tackle global warming have so far produced only gradual, halting shifts. A rapid, transformative change would require building a movement, and movements require enemies. As John F. Kennedy put it, “The civil rights movement should thank God for Bull Connor. He’s helped it as much as Abraham Lincoln.” And enemies are what climate change has lacked.

But what all these climate numbers make painfully, usefully clear is that the planet does indeed have an enemy – one far more committed to action than governments or individuals. Given this hard math, we need to view the fossil-fuel industry in a new light. It has become a rogue industry, reckless like no other force on Earth. It is Public Enemy Number One to the survival of our planetary civilization. “Lots of companies do rotten things in the course of their business – pay terrible wages, make people work in sweatshops – and we pressure them to change those practices,” says veteran anti-corporate leader Naomi Klein, who is at work on a book about the climate crisis. “But these numbers make clear that with the fossil-fuel industry, wrecking the planet is their business model. It’s what they do.”

According to the Carbon Tracker report, if Exxon burns its current reserves, it would use up more than seven percent of the available atmospheric space between us and the risk of two degrees. BP is just behind, followed by the Russian firm Gazprom, then Chevron, ConocoPhillips and Shell, each of which would fill between three and four percent. Taken together, just these six firms, of the 200 listed in the Carbon Tracker report, would use up more than a quarter of the remaining two-degree budget. Severstal, the Russian mining giant, leads the list of coal companies, followed by firms like BHP Billiton and Peabody. The numbers are simply staggering – this industry, and this industry alone, holds the power to change the physics and chemistry of our planet, and they’re planning to use it.

They’re clearly cognizant of global warming – they employ some of the world’s best scientists, after all, and they’re bidding on all those oil leases made possible by the staggering melt of Arctic ice. And yet they relentlessly search for more hydrocarbons – in early March, Exxon CEO Rex Tillerson told Wall Street analysts that the company plans to spend $37 billion a year through 2016 (about $100 million a day) searching for yet more oil and gas.

There’s not a more reckless man on the planet than Tillerson. Late last month, on the same day the Colorado fires reached their height, he told a New York audience that global warming is real, but dismissed it as an “engineering problem” that has “engineering solutions.” Such as? “Changes to weather patterns that move crop-production areas around – we’ll adapt to that.” This in a week when Kentucky farmers were reporting that corn kernels were “aborting” in record heat, threatening a spike in global food prices. “The fear factor that people want to throw out there to say, ‘We just have to stop this,’ I do not accept,” Tillerson said. Of course not – if he did accept it, he’d have to keep his reserves in the ground. Which would cost him money. It’s not an engineering problem, in other words – it’s a greed problem.

You could argue that this is simply in the nature of these companies – that having found a profitable vein, they’re compelled to keep mining it, more like efficient automatons than people with free will. But as the Supreme Court has made clear, they are people of a sort. In fact, thanks to the size of its bankroll, the fossil-fuel industry has far more free will than the rest of us. These companies don’t simply exist in a world whose hungers they fulfill – they help create the boundaries of that world.

Left to our own devices, citizens might decide to regulate carbon and stop short of the brink; according to a recent poll, nearly two-thirds of Americans would back an international agreement that cut carbon emissions 90 percent by 2050. But we aren’t left to our own devices. The Koch brothers, for instance, have a combined wealth of $50 billion, meaning they trail only Bill Gates on the list of richest Americans. They’ve made most of their money in hydrocarbons, they know any system to regulate carbon would cut those profits, and they reportedly plan to lavish as much as $200 million on this year’s elections. In 2009, for the first time, the U.S. Chamber of Commerce surpassed both the Republican and Democratic National Committees on political spending; the following year, more than 90 percent of the Chamber’s cash went to GOP candidates, many of whom deny the existence of global warming. Not long ago, the Chamber even filed a brief with the EPA urging the agency not to regulate carbon – should the world’s scientists turn out to be right and the planet heats up, the Chamber advised, “populations can acclimatize to warmer climates via a range of behavioral, physiological and technological adaptations.” As radical goes, demanding that we change our physiology seems right up there.

Environmentalists, understandably, have been loath to make the fossil-fuel industry their enemy, respecting its political power and hoping instead to convince these giants that they should turn away from coal, oil and gas and transform themselves more broadly into “energy companies.” Sometimes that strategy appeared to be working – emphasis on appeared. Around the turn of the century, for instance, BP made a brief attempt to restyle itself as “Beyond Petroleum,” adapting a logo that looked like the sun and sticking solar panels on some of its gas stations. But its investments in alternative energy were never more than a tiny fraction of its budget for hydrocarbon exploration, and after a few years, many of those were wound down as new CEOs insisted on returning to the company’s “core business.” In December, BP finally closed its solar division. Shell shut down its solar and wind efforts in 2009. The five biggest oil companies have made more than $1 trillion in profits since the millennium – there’s simply too much money to be made on oil and gas and coal to go chasing after zephyrs and sunbeams.

Much of that profit stems from a single historical accident: Alone among businesses, the fossil-fuel industry is allowed to dump its main waste, carbon dioxide, for free. Nobody else gets that break – if you own a restaurant, you have to pay someone to cart away your trash, since piling it in the street would breed rats. But the fossil-fuel industry is different, and for sound historical reasons: Until a quarter-century ago, almost no one knew that CO2 was dangerous. But now that we understand that carbon is heating the planet and acidifying the oceans, its price becomes the central issue.

If you put a price on carbon, through a direct tax or other methods, it would enlist markets in the fight against global warming. Once Exxon has to pay for the damage its carbon is doing to the atmosphere, the price of its products would rise. Consumers would get a strong signal to use less fossil fuel – every time they stopped at the pump, they’d be reminded that you don’t need a semimilitary vehicle to go to the grocery store. The economic playing field would now be a level one for nonpolluting energy sources. And you could do it all without bankrupting citizens – a so-called “fee-and-dividend” scheme would put a hefty tax on coal and gas and oil, then simply divide up the proceeds, sending everyone in the country a check each month for their share of the added costs of carbon. By switching to cleaner energy sources, most people would actually come out ahead.

There’s only one problem: Putting a price on carbon would reduce the profitability of the fossil-fuel industry. After all, the answer to the question “How high should the price of carbon be?” is “High enough to keep those carbon reserves that would take us past two degrees safely in the ground.” The higher the price on carbon, the more of those reserves would be worthless. The fight, in the end, is about whether the industry will succeed in its fight to keep its special pollution break alive past the point of climate catastrophe, or whether, in the economists’ parlance, we’ll make them internalize those externalities.

It’s not clear, of course, that the power of the fossil-fuel industry can be broken. The U.K. analysts who wrote the Carbon Tracker report and drew attention to these numbers had a relatively modest goal – they simply wanted to remind investors that climate change poses a very real risk to the stock prices of energy companies. Say something so big finally happens (a giant hurricane swamps Manhattan, a megadrought wipes out Midwest agriculture) that even the political power of the industry is inadequate to restrain legislators, who manage to regulate carbon. Suddenly those Chevron reserves would be a lot less valuable, and the stock would tank. Given that risk, the Carbon Tracker report warned investors to lessen their exposure, hedge it with some big plays in alternative energy.

“The regular process of economic evolution is that businesses are left with stranded assets all the time,” says Nick Robins, who runs HSBC’s Climate Change Centre. “Think of film cameras, or typewriters. The question is not whether this will happen. It will. Pension systems have been hit by the dot-com and credit crunch. They’ll be hit by this.” Still, it hasn’t been easy to convince investors, who have shared in the oil industry’s record profits. “The reason you get bubbles,” sighs Leaton, “is that everyone thinks they’re the best analyst – that they’ll go to the edge of the cliff and then jump back when everyone else goes over.”

So pure self-interest probably won’t spark a transformative challenge to fossil fuel. But moral outrage just might – and that’s the real meaning of this new math. It could, plausibly, give rise to a real movement.

Once, in recent corporate history, anger forced an industry to make basic changes. That was the campaign in the 1980s demanding divestment from companies doing business in South Africa. It rose first on college campuses and then spread to municipal and state governments; 155 campuses eventually divested, and by the end of the decade, more than 80 cities, 25 states and 19 counties had taken some form of binding economic action against companies connected to the apartheid regime. “The end of apartheid stands as one of the crowning accomplishments of the past century,” as Archbishop Desmond Tutu put it, “but we would not have succeeded without the help of international pressure,” especially from “the divestment movement of the 1980s.”

The fossil-fuel industry is obviously a tougher opponent, and even if you could force the hand of particular companies, you’d still have to figure out a strategy for dealing with all the sovereign nations that, in effect, act as fossil-fuel companies. But the link for college students is even more obvious in this case. If their college’s endowment portfolio has fossil-fuel stock, then their educations are being subsidized by investments that guarantee they won’t have much of a planet on which to make use of their degree. (The same logic applies to the world’s largest investors, pension funds, which are also theoretically interested in the future – that’s when their members will “enjoy their retirement.”) “Given the severity of the climate crisis, a comparable demand that our institutions dump stock from companies that are destroying the planet would not only be appropriate but effective,” says Bob Massie, a former anti-apartheid activist who helped found the Investor Network on Climate Risk. “The message is simple: We have had enough. We must sever the ties with those who profit from climate change – now.”

Movements rarely have predictable outcomes. But any campaign that weakens the fossil-fuel industry’s political standing clearly increases the chances of retiring its special breaks. Consider President Obama’s signal achievement in the climate fight, the large increase he won in mileage requirements for cars. Scientists, environmentalists and engineers had advocated such policies for decades, but until Detroit came under severe financial pressure, it was politically powerful enough to fend them off. If people come to understand the cold, mathematical truth – that the fossil-fuel industry is systematically undermining the planet’s physical systems – it might weaken it enough to matter politically. Exxon and their ilk might drop their opposition to a fee-and-dividend solution; they might even decide to become true energy companies, this time for real.

Even if such a campaign is possible, however, we may have waited too long to start it. To make a real difference – to keep us under a temperature increase of two degrees – you’d need to change carbon pricing in Washington, and then use that victory to leverage similar shifts around the world. At this point, what happens in the U.S. is most important for how it will influence China and India, where emissions are growing fastest. (In early June, researchers concluded that China has probably under-reported its emissions by up to 20 percent.) The three numbers I’ve described are daunting – they may define an essentially impossible future. But at least they provide intellectual clarity about the greatest challenge humans have ever faced. We know how much we can burn, and we know who’s planning to burn more. Climate change operates on a geological scale and time frame, but it’s not an impersonal force of nature; the more carefully you do the math, the more thoroughly you realize that this is, at bottom, a moral issue; we have met the enemy and they is Shell.

Meanwhile the tide of numbers continues. The week after the Rio conference limped to its conclusion, Arctic sea ice hit the lowest level ever recorded for that date. Last month, on a single weekend, Tropical Storm Debby dumped more than 20 inches of rain on Florida – the earliest the season’s fourth-named cyclone has ever arrived. At the same time, the largest fire in New Mexico history burned on, and the most destructive fire in Colorado’s annals claimed 346 homes in Colorado Springs – breaking a record set the week before in Fort Collins. This month, scientists issued a new study concluding that global warming has dramatically increased the likelihood of severe heat and drought – days after a heat wave across the Plains and Midwest broke records that had stood since the Dust Bowl, threatening this year’s harvest. You want a big number? In the course of this month, a quadrillion kernels of corn need to pollinate across the grain belt, something they can’t do if temperatures remain off the charts. Just like us, our crops are adapted to the Holocene, the 11,000-year period of climatic stability we’re now leaving… in the dust.

Filmmakers Propose Online “Swarm Offensive” Against Climate Change (Yes!)

Open source software brought us Linux and Wikipedia. Can it help us tackle the challenge of climate change?

by

Coalition Of The Willing from coalitionfilm on Vimeo.

This beautifully animated short video argues that grassroots efforts to deal with climate change can be more effective if they adopt the tactics of open source technology, using databases and social networks to “tap into our collective genius” to tackle the toughest of global challenges.

The art featured in the film was crafted by a group of 24 artists from around the world.

The film characterizes the counterculture of the 1960s as a highly networked and decentralized movement that challenged capitalism—and calls for a similar but more technologically savvy attack on climate change.

And then there’s the scene in which Ronald Reagan literally snorts hippies like cocaine through a twenty-dollar bill.

“Coalition of the Willing” was produced and directed by the British animator Simon Robson—better known as Knife Party—and written by author Tim Rayner. The art featured in the film was crafted by a group of 24 artists from around the world, including leaders in digital animation such as Decoy, World Leaders, and Parasol Island.

China, the Climate and the Fate of the Planet (Rolling Stone)

If the world’s biggest polluter doesn’t radically reduce the amount of coal it burns, nothing anyone does to stabilize the climate will matter. Inside the slow, frustrating — and maybe even hopeful — struggle to find a new way forward

 By | September 15, 2014

As the sun rises in mid-july over andrews Air Force Base near Washington, D.C., Secretary of State John Kerry climbs quickly – he’s positively bouncing – up the carpeted stairs of his blue-and-white government­issue 757. Kerry is heading to Beijing to talk with Chinese leaders about, among other things, one of President Obama’s top priorities in the waning days of his second term: the urgent need to reduce carbon pollution and limit the damage from climate change. But the rest of the world isn’t cutting Kerry any slack right now – there’s trouble with the elections in Afghanistan, rising conflict in the Middle East and upcoming negotiations with Iran on nuclear weapons. As he ducks into the plane, Kerry is already talking intensely on his cellphone, deeply wired into the global chaos. An aide shoulders his bags as well as a large black case that contains his acoustic guitar, which he takes with him everywhere and often plays late at night when he’s alone in his hotel room.

For nearly a decade, the U.S. and China, the two most powerful nations on the planet, have met every year to talk about how to run the world together. When the talks began in 2006, they focused on issues like currency-exchange rates, trade barriers and China’s never-ending disputes with Taiwan. In 2009, shortly after Obama’s inauguration, the U.S. pushed to add climate change to the mix, hoping that a better understanding between the U.S. and China would lead to a better deal at the Copenhagen climate summit that year. (It didn’t help – mistrust between the countries was a large part of the reason why the talks imploded.)

This year’s U.S. delegation includes many of the administration’s most influential climate hawks – Energy Secretary Ernest Moniz, top climate negotiator Todd Stern and John Podesta, counselor to Obama, who has become the administration’s de facto point man for climate policy. This is the diplomatic equivalent of a full-court press. In the past couple of years, Obama has made some important moves, including investing billions in clean energy, jacking up vehicle-efficiency standards and proposing rules to limit pollution from U.S. coal plants. But climate change is a global issue. Unless the West can persuade other countries to take climate action seriously, nothing any single nation does is going to matter much when it comes to solving the problem.

Except, that is, for China. The blunt truth is that what China decides to do in the next decade will likely determine whether or not mankind can halt – or at least ameliorate – global warming. The view among a number of prominent climate scientists is that if China’s emissions peak around 2025, we may – just barely – have a shot at stabilizing the climate before all hell breaks loose. But the Chinese have resisted international pressure to curb their emissions. For years, they have used the argument that they are poor, the West is rich, and that the high levels of carbon in the atmosphere were caused by America’s and Europe’s 200-year-long fossil­fuel binge. Climate change is your problem, they argued – you deal with it. But that logic doesn’t hold anymore. China is set to become the largest economy in the world this year, and in 2006, it passed the U.S. as the planet’s largest carbon polluter. China now dumps 10 billion tons of CO2 into the atmosphere every year. That number is expected to grow to 15 billion tons by 2030, dwarfing the pollution of the rest of the world. If that happens, then the chances that the world will cut carbon pollution quickly enough to avert dangerous climate change is, according to Kevin Anderson, deputy director of the Tyndall Centre for Climate Change Research in the U.K., “virtually zero.”

John Kerry knows this. He also knows that when the nations of the world gather in Paris next December to try to hammer out a global climate agreement, it may be the last best chance to address this problem before the Years of Living Dangerously begin. Like other climate negotiations held under the banner of the United Nations Framework Convention on Climate Change, the Paris meeting is likely to be warped by 25-year-old grudges and a profound sense of distrust. “But right now, Paris is the only game we have,” one member of the State Department’s climate team told me. “If it fails, there is no Plan B.”

In Beijing, one of Kerry’s goals will be to find out all he can about China’s strategy for Paris – what kind of commitment the Chinese might make, how sincere they are, what tactics they will use. But for Kerry, this is anything but a straightforward conversation, because it’s twisted up in the shadow play of U.S.-China relations, which are marked by suspicion, paranoia and saber rattling on both sides as the U.S. adjusts to China’s rising power in the world. “What we are living through now is the end of 500 years of Western predominance,” historian Niall Ferguson has written. The issue is not whether China will challenge America’s dominance, but when and how.

Shortly before takeoff, Kerry wanders down the aisle to chat. He talks idly about his July 4th celebration and the recent storm damages to his house on Nantucket. But when asked about his expectations for the Beijing summit, he looks grave: “Frankly, we’re not sure where this is all going.” He remembers what happened in Kyoto, Japan, in 1997, when the U.S. was mocked for signing an agreement that the Senate would never ratify, and in Copenhagen in 2009, when Obama arrived at a conference that was supposed to save the world but ended up being gridlocked by squabbles over money and emissions targets. Kerry is determined not to let that happen again.

After 25 years of failed climate negotiations, it’s easy to be cynical about the upcoming talks in Paris. But there are at least three factors that make a meaningful agreement next year possible.

The first is that climate change is no longer a hypothetical problem – it’s happening in real time all around us. Droughts, floods, more destructive storms, weird weather of all sorts – just look out your window. In the latest reports from the Intergovernmental Panel on Climate Change, the world’s top scientists called the fact that the Earth is warming “unequivocal” and stated that humans are the cause of it. Without dramatic action, the planet could warm up as much as 4 degrees Celsius (7.2 F) by the end of the century, which would be catastrophic. As Kerry said of a report last September, “The response must be all hands on deck. It’s not about one country making a demand of another. It’s the science itself demanding action from all of us.”

The second factor is that until now, the biggest obstacle to an international agreement to reduce carbon pollution has been the United States. But that’s starting to change. Thanks to Obama’s recent crackdown on pollution, as well as the boom in cheap natural gas, which has displaced dirty coal, carbon emissions in the U.S. are on the decline. “What the president has done is very important,” says Robert Stavins, director of the Harvard Project on Climate Agreements. “It allows the U.S. to look at other countries and say, ‘Hey, what are you doing?'”

The final reason for hope, paradoxically, is China’s relentless demand for energy. China is in the midst of a profound economic and social transformation, trying to reinvent itself from an economy based on selling cheap goods overseas to an economy based on selling quality consumer goods at home, while keeping growth rates high and cutting dependence on fossil fuels. Energy demand is expected to double by 2030, and at that pace, there is not enough oil, coal and gas in the world to keep their economy humming. So China’s ongoing energy security depends on the nation developing alternative energy sources in a big way. “We need more of everything,” says Peggy Liu, a sustainability leader who works across China. “Wind, solar, a modernized grid. We need to leapfrog over the past and into a clean-energy future.”

China’s leaders are also waking up to the fact that recent decades of hypergrowth, most of it fired by coal, have exacted a steep price. Air pollution in China’s big cities is among the worst in the world; one recent report found that poor air quality contributed to 1.2 million premature deaths in 2010. As Hank Paulson, former Secretary of the Treasury and longtime China observer, has put it, “What is another point of GDP worth, if dirty air is killing people?” Earlier this year, a riot broke out in Zhongtai, a town in eastern China, when protests against a new waste incinerator turned violent, leaving police vehicles torched and at least 39 people injured; in southern China, protests erupted over the construction of a coal-fired power plant. Similar clashes are increasingly frequent in China as pollution-related illnesses rise.

And it’s not just the air that’s a problem in China. More than 20 percent of the country’s farmland is polluted. Sixty percent of its groundwater supply is unfit for human consumption. Rivers are industrial sewers. Last year, 16,000 swollen and rotting dead pigs were found dumped in the Huangpu River near Shanghai.

What looks to be the impacts of climate change are starting to register too. Droughts have become longer and more frequent, forcing China to import ever-increasing amounts of staples like wheat and soy. By one count, 28,000 rivers in China have vanished. China’s southern provinces have the opposite problem: devastating floods as a result of intense rainfall. In addition, much of the coastline, including cities like Shanghai, are highly vulnerable to sea-level rise.

Chinese leaders know this trajectory is unsustainable – economically and politically. Earlier this year, Premier Li Keqiang “declared war” on pollution. Party leaders in China now routinely talk about the importance of “rebalancing the economy” and creating an “ecological civilization.” China Daily, the Communist Party house organ, regularly runs stories about air pollution and toxic waste. While I was in Beijing, I asked U.S. Ambassador to China Max Baucus why the Chinese were now willing to talk so openly about environmental issues. “The fragility of their government,” he said bluntly. “They will have a social revolt on their hands if they don’t come up with a way of dealing with this.”

Pollution from coal plants

So a big push for clean energy makes a lot of sense. In fact, you could easily argue that China has already done far more than the U.S. to transform its energy supply: Including hydropower, renewables now make up 20 percent of the energy mix (compared to 13 percent in the U.S.), a share targeted to double by 2030. China is the largest producer of wind and solar power on the planet. In 2013, nearly 60 percent of new-power generation was renewable. They also have 28 new nuclear plants under construction, more than any other country. Policywise, Chinese leaders have also been innovative. In the U.S., neither a carbon tax nor a cap-and-trade system to put a price on carbon pollution is under serious consideration; in contrast, China’s carbon-trading program, which includes more than 2,000 pollution sources, is the second-largest trading system in the world (after the EU’s). “If China is successful in using market forces to cap carbon and transform its economy, that may be the best shot we have to limit climate change,” says Dan Dudek, vice president of the Environmental Defense Fund.

The problem for China, in a word, is coal: About 70 percent of the country’s electrical power comes from burning dirty rocks. The Chinese consumed nearly 4 billion tons in 2012, almost as much as the rest of the world combined. Like the oil industry in the U.S., the coal industry has enormous sway in China, making it all the more difficult to kick the habit. But as the rising power of the 21st century, China is under enormous political pressure to behave responsibly, lest it be seen as a pariah like Russia. “The choices that Chinese leaders make in the next decade will be absolutely pivotal to solving the climate crisis,” says former Vice President Al Gore. And for China’s economic and social stability, the consequences couldn’t be higher. “Politically, it’s very difficult to be fingered as the one most responsible for a looming catastrophe,” Gore continues. Or, as Harvard’s Stavins says, “If it’s your century, you don’t obstruct – you lead.”

In the decade or so after 9/11, when U.S. foreign policy revolved around hunting down and killing Islamic terrorists, we didn’t make China a priority. Then in 2011, the Obama administration announced an “Asia pivot” in U.S. foreign policy to counter China’s rising influence. Among other things, the U.S. increased its military presence and surveillance missions in the region, stoking suspicion in China that one of the goals of U.S. foreign policy is to “contain” China – both economically and militarily (if it were, the U.S. was certainly not going to admit it).

China’s response only seemed to play into our fears. China had been investing in new long-range missiles, upgrading its navy, and began using its new muscle­ to claim disputed territory in the South China Sea. China has been playing more subtle games, too: blocking access to Google and The New York Times, and having hackers raid computers at a number of U.S. corporations, stealing trade secrets. Foreign-policy journals openly speculate about the possibility of war with China, a suggestion that U.S. officials dismiss as absurd. “If there is a war between the U.S. and China,” argues Cheng Li, director of the China program at the Brookings Institution, “it will not be over economics or security, it will be because of misjudgment and misunderstanding.”

Of course, even the most rabid warmongers realize that a war between the U.S. and China would be disastrous. That’s one reason why leaders on both sides are looking for common ground – and two of the biggest shared interests are climate and energy. “In a relationship fraught with tension, these are places where we can do business,” says Obama’s adviser Podesta.

On the flight to Beijing, there is a lot of talk about what that common ground between the U.S. and China might look like. Granted, climate catastrophe is bad for everyone. But what leverage does the U.S. really have over China? On a practical level, the Chinese would like access to American technology. (“The deal here is that the U.S. will let you buy lots of energy equipment at exorbitant prices,” jokes one journalist on the flight.) But the Chinese also understand that, given the GOP-held Congress, Obama doesn’t have the power to make any big future commitments to cut carbon pollution – and so why should they?

On a more human level, there’s also a lot of nervousness about China’s notorious difficulty as a negotiating partner. “China has a very top-down culture – you have to speak to people right at the top,” one of Kerry’s top advisers tells me. “And they are very motivated on climate, due to air-pollution issues. But it’s hard to get China to do hard things, in part because, unlike other Asian countries, doing things for the greater good is not a big motivation for them.”

The mismatch between the urgency of taking action and the self-destructive diddling of diplomacy is frightening to witness. A few weeks before heading to China with Kerry, I attended a UNFCCC climate conference in Bonn, Germany. The two-week-long meeting, one of several designed to begin mapping out an agreement for Paris next year, was held in the gray, bureaucratic-feeling Maritim Hotel near the banks of the Rhine and attended by nearly 2,000 delegates from more than 180 countries. But neither John Kerry nor Todd Stern was anywhere to be found; the U.S. delegation was headed by Trigg Talley, an affable white-haired man who is one of Stern’s deputies. If Bonn was a preview of how things will go next year in Paris, then you can kiss human civilization goodbye. Because nothing will get done. And if it appears that something might get done, you can be sure that somebody – most likely the Saudis, who are infamous for their ability to throw a monkey wrench into negotiations at the last minute – will do everything they can to derail it.

The sheer tedium of the discussions is difficult to capture, but let me try: During the plenary session on the final day, which was held in a conference room the size of a football field and was supposed to be where important breakthroughs were announced, I listened for hours to delegates from Singapore discuss the kind of formatting that should be used on the proposal and to delegates from Bolivia argue that bullet points should be used, not paragraph breaks. I never heard the words “carbon” or “greenhouse gas” in the entire session (although “adaptation” got tossed around a lot). The most memorable words were spoken by a delegate from South Africa: “We are sheep in need of herding.”

In Bonn, the stench of nearly 25 years of broken promises and failed agreements was palpable. The U.S. was viewed with particular skepticism and disdain, not just because the U.S. signed but then failed to ratify the Kyoto Protocol, but because until this administration, American presidents and congressional leaders never did anything intentional to substantively curb carbon pollution, despite the obvious impacts it would have on poorer nations. “You talk a lot, but you are not sincere,” one Turkish delegate sniffed to me. Trust in U.S. negotiators had been further undermined when documents made public by WikiLeaks and Edward Snowden revealed that the U.S. had been spying on negotiators from other countries before and during Copenhagen, trying to gain intelligence on their positions. The revelations were particularly damning given the good-faith nature of climate negotiations. “After almost 30 years of this kind of thing,” one longtime participant in these talks puts it, “what measure of trust can possibly exist? How do you strike a deal on issues that are central to your country’s survival with someone you think is out to screw you?”

Issues of trust aside, several things are immediately apparent to me in Bonn about the content and design of the agreement that is likely to emerge in Paris next year. One is that it is going to disappoint and anger a lot of people, particularly those who think the job of a climate treaty is to force big polluters to change their ways. The Paris agreement will largely be a “bottom up” treaty, in which each country will put forward a “contribution” for what each is willing to do to reduce carbon pollution. Those contributions will then be reviewed in the future – exactly how and by whom isn’t clear – to make sure each nation is keeping its promise. There will be no legally binding caps on emissions, no mandated “targets” that countries need to reach. In fact, it will not be a treaty at all (a treaty would need to be ratified by the U.S. Senate, which everyone knows will never happen). It will likely be an agreement “with legal force,” which means, basically, that some parts of the agreement might be legally binding in some countries.

However toothless this approach might seem, there is logic behind it. Since Kyoto, international climate efforts have largely failed because they were too prescriptive. Few nations were willing to bow to the demands of an international carbon police. And beyond that, there was no way to enforce carbon limits.

But even if the talks succeed in creating a sustainable basis for international cooperation, whatever emerges from Paris next year is extremely unlikely to put the world on a path that would limit warming to below 2 degrees Celsius (3.6 F), which was enshrined in the Copenhagen Accord as the threshold for dangerous climate change. For that to happen, says the Tyndall Centre’s Kevin Anderson, “global emissions from energy need to reach a peak by around 2020, and then rapidly reduce to zero by 2050 at the latest.” “I’m not giving up hope,” Kerry told me. “Physically, it’s possible. But politically, it will be very difficult.” Podesta is even more blunt. “If we wait until we have a binding international agreement that actually puts us on track for 2 C,” he says, “we’ll hit 2 C before we get an agreement. But we have to get started if we hope to get to the destination.”

The second revelation is that the Paris agreement is likely to be more about money than about carbon. That is not inappropriate: Climate change is, at its base, an environmental-justice issue, in which the rich nations of the world are inflicting damage on the poor ones. One question that has always haunted climate agreements is, how should the victims be compensated? In past U.N. agreements, developed countries have promised aid to poorer nations. But in translating these general commitments into hard numbers, says Elliot Diringer, a climate-policy expert at the Center for Climate and Energy Solutions, “the cash flows really have never been enough.”

In Paris, they will try again. The delivery vehicle of choice is called the Green Climate Fund, which was one of the few concrete accomplishments to come out of Copenhagen. The idea is simple: Rich countries pay into the fund, the fund’s 24-member board examines proposals from developing countries for clean-energy and climate-adaptation projects, and then it awards funds to those it finds worthy.

The Green Climate Fund was born in the closing days of the Copenhagen negotiations, when then-Secretary of State Hillary Clinton tried to lure China and other developing nations into a deal by promising that, in exchange for agreeing to a binding cap on carbon pollution as well as outside monitoring and verification of pollution rates, rich nations like the U.S. would pledge a combined $100 billion a year to help poor nations. Many negotiators thought it was a clever (or not so clever) ploy by the U.S. to make China take the fall for the collapse of the Copenhagen deal, since it was clear that China considers emissions data a state secret and would never allow outsiders to pore through the books. But regardless of the intentions, the deal fell apart. The $100 billion promise lingered, however, and was codified in later agreements. (Although $100 billion sounds like a lot, it’s a small part of the $1 trillion a year that will be necessary to transform the energy system.)

Right now, developed nations have a long way to go to live up to Clinton’s promise. The Green Climate Fund has taken four years to get up and running, and still nobody knows if it will primarily make loans or grants. So far, only Germany has come through with a meaningful pledge, offering $1 billion over the next nine years. Stern says the U.S. is putting “a lot of blood, sweat and tears” into getting the fund set up right, and that the $100 billion a year will come from a variety of sources, including private investment. But if the point of the fund is to demonstrate the commitment of rich nations to help the poor, it will need them to make real financial commitments. “Big new public funds are not viable,” says David Victor, a climate-policy expert at the University of California, San Diego. “This could be a train wreck of false expectations.”

In Bonn, the biggest question on many negotiator’s minds was, “Will China step up?” Despite the fact that China is the biggest carbon emitter on the planet, with the most dynamic economy in the world, the Chinese remain wedded to a 25-year-old idea that China is still a developing country, in the same category as, say, Uganda, and therefore not responsible for taking action. At least, not until the U.S. and the EU – which, with their cumulative emissions, have essentially caused the problem of global warming – take the first step. Among negotiators, China’s stance is widely viewed as a negotiating tactic to lower expectations for action and to allow it to play moral defender for other developing nations, some of whom fear that if China makes a big move, it will increase the pressure on them to do the same.

I got a preview of the kind of arguments U.S. negotiators will face when I bumped into Zou Ji, the deputy director general for the National Center for Climate Change Strategy and International Cooperation and a key member of the Chinese negotiating team, in the lobby of the Maritim Hotel. I asked him if the recent action by Obama to limit pollution from power plants and increase fuel-efficiency standards had changed the dynamics in the negotiations. “It is a good thing,” Ji told me. “But now, America says to us, ‘Your turn to step up.’ Well, we welcome what you have done, but we want to see more action from the U.S. first. It is very clear that Congress is a big constraint for you; Obama can only do what he can do.” Ji argues, accurately, that the U.S. is still the far richer country, and while China’s carbon emissions are enormous, if you break it down to per-capita emissions, the average American is responsible for dumping almost three times as much CO2 into the atmosphere every year as the average Chinese.

I point out to him that this is true, but that cumulative emissions in China will soon dwarf those in the United States.

“China needs to do its part, but right now the U.S. still has huge potential to do more,” he says forcefully. “I have lived in the U.S., where everyone has a clothes dryer and an air conditioner and a big refrigerator and a big house and a big car. In the EU and Japan, they also live well, but people there only consume half the energy Americans do. You do have the capacity to live at the same standard and consume far less – if you choose.”

When Kerry’s plane lands in Beijing, we immediately jump into a line of SUVs and are whisked away to the Great Wall just north of the city for what one State Department staffer calls “a little cultural sightseeing.” When I visited the wall a few years ago, the air pollution was so bad, I could hardly see 15 feet in front of me; today, it’s clear enough to see the Xishan Mountains, which are 12 miles away at the western edge of the city. Kerry strolls along the wall with Chinese dignitaries, then we motorcade to the Marriott hotel in central Beijing, where the U.S. government has taken over two floors. Security is high: The entrance to the hotel is blocked, and armed agents are everywhere. The biggest concern seems to be Chinese spies; on an earlier trip to China, five members of Todd Stern’s team received spoof e-mails that contained a bot that could have given a hacker control of their computers, and shortly after I check into my hotel, I am told that I can assume my room is bugged and my e-mail is read. Across the street from the hotel is an Apple Store, Gucci, Hermès and, strangely, a coal-fired power plant with clouds and a blue sky painted on the sides, as if to disguise the dirty black rocks burning within.

The next morning, Chinese President Xi Jinping opens the talks at the Diaoyutai State Guesthouse, an elegant retreat in western Beijing. His address to 500 or so American and Chinese dignitaries isn’t exactly a rousing call to action on climate change. Instead, he talks about the importance of keeping the Chinese economy humming, declaring that China needs a peaceful and stable environment “more than ever.” Xi is a tough-looking guy with a Tony Soprano vibe, and his speech leaves no doubt that he sees China as the rising power. “It is natural that China and the U.S. may have different views, and even frictions, on certain issues,” he says. Then he adds, “Confrontation between China and the United States would definitely spell disaster for the two countries and for the wider world.” Xi only mentions climate change once, in a passing reference to it as a significant challenge that both nations face.

Xi, who came to power in 2013, is “a very strong leader for China,” says Cheng Li of the Brookings Institution. Li contrasts him with other recent Chinese leaders, most of whom tended to be pale figures who dutifully rose through the ranks of the Communist Party. Xi, who is 61, rules with authority and efficiency. He grew up the son of a deputy prime minister and revolutionary who was known as an architect of China’s special economic zones, which were important drivers in the liberalization of China. As president, Xi has cracked down on corruption and is a fierce defender of Chinese interests in disputed territories like the South China Sea. He has also toughened up China’s internal security forces (China spends more on domestic security than it does on national defense). But U.S. officials who have had close contact with Xi are impressed by his directness. One White House staffer pointed to a recent agreement to reduce hydrofluorocarbons, a potent greenhouse gas, that Xi worked out with Obama last year. “Xi rolled the Chinese bureaucracy to get that done,” the staffer says. Kerry also sees him as an effective leader. “I had long conversations with Xi while I was chair of the Foreign Relations Committee,” he tells me. “The kind of action we’ve seen in China recently doesn’t happen without his personal commitment.”

When Kerry takes the podium after Xi steps down, he is conciliatory. He reassures Xi and other Chinese leaders in the room that the U.S. does not seek to “contain” China, and that it welcomes the emergence of “a peaceful, prosperous China that . . . chooses to play a responsible role in world affairs.” He, too, talks a lot about economic growth and how “the true measure of our success will not be just whether our countries grow, but how our countries grow.” Kerry continues, “Step by step, we are shifting our focus . . . to the inescapable reality of a clean-energy future.”

When Kerry travels to countries where the U.S. might be perceived to have the upper hand, he can be very blunt about the potential ravages of climate change. A few months ago, in a speech in Jakarta, Indonesia, he called it the “world’s most fearsome” weapon of mass destruction. But Kerry doesn’t say a word here about melting ice caps, rising seas or weapons of mass destruction. Instead, he talks about how clean energy is “the biggest market the world has ever seen.” He talks investment flows, technology sharing and pollution-free prosperity. “Our goal,” Podesta tells me, “is to create a virtuous circle in the Pacific, where they match our ambition, and then we match theirs.”

For the U.S., pushing for action is imperative: If China makes an aggressive move on carbon, it kills a favorite political talking point from climate deniers in Congress. “I can’t tell you how many meetings I’ve sat in where the subject of ‘What is China doing?’ comes up,” says Podesta. “For us, it’s important that we take that objection off the table.”

For the Chinese, beyond the obvious motivation to clean up the air, the question is what they want from the U.S. in return. As Kerry put it to me later, “The Chinese have a lot of stuff they want from us. We have natural gas. We have coal. We have clean-energy technology.” How this bargaining works out is the heart of the negotiations and gets into complex areas like protection of intellectual property rights. In the past, the Chinese simply wanted to buy our technology, copy it and manufacture it more cheaply than anyone else. “But that dynamic has changed,” says one Department of Energy official. “Now the deals are much more about joint ventures and shared investment.”

Later in the day, top members of the U.S. and China delegations meet in a conference room on the second floor for the Joint Session on Climate Change and Clean Energy. It is a stiffly formal scene, with Kerry, Podesta, Stern, U.S. Energy Secretary Moniz and science adviser John Holdren on one side of a long mahogany table, and Chinese leaders, including Vice Premier Wang Yang and lead climate negotiator Xie Zhenhua, on the other side. In this more intimate group, the Chinese are much blunter and more forthright about the risks of climate change. But it isn’t clear if this is because they feel more relaxed or because they are more willing to say what the U.S. wants to hear. State Councilor Yang, who opens the discussion, calls climate change “a common and grave challenge to mankind.” He talks about actions the Chinese government has taken to promote clean energy and efficiency, and he underscores China’s support of the UNFCCC climate negotiations. “We have also maintained close dialogue in consultation on [the U.S.’s and China’s] respective climate-change policies,” he says.

Kerry nods politely and then reads from prepared remarks: “Every one of us in this room is well aware that the climate crisis is one that respects no border. It’s transboundary. It affects the planet.”

The Chinese leaders listen carefully, just as the American team listened carefully to Yang’s remarks, attuned to nuances and gestures that gain trust or lose it, that show respect or haughtiness. And yet, I get the strong sense at this meeting, and at every other one I’ve attended, that 15 levels of chess are being played, that the motives and impulses of each side remain unknowable to the other, and that both sides are making calculations that will shape their careers, their economies and the future of the planet. And always the fear – expressed in the glint of an eye, a moment of hesitation – that each is being played. The Chinese worry that the U.S. won’t keep their word or has a secret plan to thwart their economic growth; the Americans worry that the Chinese are using shady data, and that they are only in it for the money.

Sometimes, the enormous gap between how the Chinese run their country and how the Americans run theirs reveals itself. One of those moments occurs on the second day of the talks in the Great Hall of the People in Tiananmen Square, which is China’s parliamentary chamber. Kerry and Yang appear at a press conference to bestow six “EcoPartnership” awards to American and Chinese organizations that are collaborating on clean-energy and climate solutions. In the context of the talks, it is a small-bore event, with a handful of dignitaries and some Chinese press.

But maybe because of this, Kerry’s remarks at the event are looser and less diplomatic than anything I’ve heard him say earlier. They are also more dangerous politically, because he talks about the one thing the Chinese leadership is most afraid of: the power of social activism. He describes how, in 1970, after 20 million Americans attended Earth Day rallies, public outrage led to the creation of the Environmental Protection Agency, as well as the passage of the Clean Air Act and, later, the Clean Water Act. “So I have seen the power of grassroots action, of local efforts becoming magnified and ultimately creating action at a larger, federal level,” Kerry says, his voice rising. “And I see that same kind of drive, that same kernel of innovation, and of demand for a difference, right here [in China], today.”

Kerry’s larger point is undoubtedly true – there is a rising consciousness of environmental issues in China, a sense that civilized societies don’t let their rivers catch fire. But as Kerry knows very well, there will be no organized demonstrations of millions of people marching on the streets in China, demanding change. If they tried, they would likely be tear-gassed or thrown in jail. Activism, such as it is in China, is either well-behaved and sanctioned by the state, or it is deemed reckless and dangerous and quickly shut down.

After his remarks at the Great Hall of the People, Kerry gets polite applause and then sits down to listen to a boilerplate speech from Yang. If anyone noticed that the secretary of state of the United States had just suggested that a populist movement in the People’s Republic of China could challenge the status quo, it wasn’t apparent.

One person who understands the dangers of social activism as well as anyone is Shuo Li, 27, a climate-policy officer for Greenpeace East Asia. Shortly after Kerry’s talk, I visited Li at Greenpeace’s office in Beijing. A year earlier, Greenpeace had published an investigation into the development of a coal-to-liquids plant in Inner Mongolia. Transforming coal into liquid fuels like diesel (or, in a similar process, natural gas) is expensive and, more importantly, an environmental disaster. Compared with typical refining processes, coal liquefaction produces 14 times the amount of carbon dioxide.

What’s interesting about Greenpeace’s investigation is that it targeted the owner of the plant, Shenhua Group, which is China’s biggest coal producer and a political powerhouse. (“Shenhua is the monster,” Li says.) In the U.S., enviros go after big companies all the time. But in China, this kind of action is unprecedented. As was its effectiveness. Li says the company called in Greenpeace, and Shenhua agreed to quit pumping out groundwater for use in the plant.

I ask Li if this is a sign that Chinese leaders are becoming more tolerant of environmental activism?

“Maybe a little,” Li says. He explains that unlike, say, publicly celebrating the Dalai Lama or arguing for the ethical treatment of the Uighur minority in China, it’s OK to raise questions about environmental problems. “But you have to do it the right way. You can go after local officials or individual power plants.” But, as he points out, there is no clear line between what is acceptable and what is not. “That is something everyone has to discover for themselves,” he says. He adds with a sly smile: “For the government, it is more effective that way.”

But Li knows he’s treading dangerous ground. In 2012, a 65-year-old former forestry official was threatened with five years in prison for publishing and distributing books that questioned the overdevelopment of Hainan Island in southern China. (He received a three-year suspended sentence and a fine.) Two years earlier, one of Beijing’s most respected science reporters, Fang Xuanchang, who earned a reputation for calling bullshit on many government-funded research projects, was brutally beaten on his way home from work. His assailants were never found. The message, as one journalist wrote in Foreign Policy, was clear: “Don’t go there, or you could be next.”

I asked about the rising number of protests around the country against industrial plants found to be dumping chemicals­ into rivers, or protesters throwing bricks at police to halt the construction of a new power plant. “Individual NIMBY actions are acceptable,” Li says. “But when you try to mobilize people on a larger scale, that is when you get in trouble.”

“Trouble, how?”

“You don’t even want to think about it,” Li answers, fear flashing in his eyes.

The rise of China, which was driven by the biggest and fastest industrial revolution the world has ever seen, was fueled almost entirely by coal. And its continued success – not to mention, in many ways, the fate of human civilization – depends on how quickly it can wean itself off this cheap, dirty, abundant fossil fuel. “The big question,” Moniz told me in Beijing, “is how fast they can bend down the curve of coal.”

“Bending down the curve of coal” is geek-speak for reducing dependency on coal. Because coal – by far the most carbon­intensive fossil fuel – will most likely be replaced by cleaner energy sources; in that case, the moment China’s coal consumption plateaus will also be the moment their greenhouse-gas pollution plateaus. And that could be the moment the world begins a transition toward a stable climate.

But the question is: When will that moment occur? In China, this question will not be answered by the invisible hand of the market but, ultimately, by the strong hand of President Xi and other party leaders. Xi and his advisers will make a complex economic and political calculation about how far they want to push clean energy – and whether they want to encourage a shift away from coal by, say, expanding the existing carbon-trading market, passing a straightforward tax on carbon, or simply issuing a dictum that caps the amount of coal the nation can consume. A few weeks before my conversation with Moniz, a respected Chinese academic had speculated that China would cap coal consumption by 2030. “That would be a big step in the right direction,” Gore told me. But as Gore well knows, unless that cap is followed by a radical and almost unimaginable global shift toward zero-carbon energy, it’s not a big enough step to avert climate chaos in the coming decades.

China has already taken a number of measures to move away from coal. It is reportedly closing down 50,000 small coal-fired furnaces and has essentially stopped building new coal plants in big eastern cities like Beijing and Shanghai. In 2020, burning coal will be banned in Beijing. But given the enormity of China’s coal addiction, these are just baby steps compared to what is needed.

And that’s one reason why the Chinese are very interested in natural gas. Natural gas has about half the carbon of coal, and burning it creates much less air pollution. China has the biggest shale-gas reserves in the world and would dearly like to unleash an American-style fracking boom (which is its own kind of environmental nightmare, of course). But the technology used to extract the gas from shale, which was invented in the U.S., is complex and not easy to replicate. In addition, shale gas in China is more deeply buried than in the U.S., and the soil is less porous, making the gas more difficult to extract. And thanks to methane leaks during fracking operations (methane, the principal component of natural gas, is a short-lived but potent greenhouse gas), the climate benefits of natural gas are questionable.

Imagining a fracked-out China is not pretty, but it might beat the alternative – making natural gas out of coal. The process is similar to the coal-to-liquids plant in Inner Mongolia that Greenpeace singled out, and like that process, it is both water- and carbon-intensive. China already has two coal-to-gas plants in operation, with as many as 48 more on the drawing board. Most of them are slated to be built in western China, far from population centers, where Chinese leaders are eager to spur development and provide jobs. But the cost to the atmosphere will be enormous. If all of these plants get built, they will collectively emit more than a billion tons of CO2 each year – more than the entire nation of Germany emitted last year.

Moniz calls coal-to-gas plants in western China “a major issue” for Chinese and U.S. negotiators. “Burning natural gas may help them solve the problem of air pollution,” says Moniz. “But if they get it by manufacturing it from coal, they will be creating another, much larger problem.” And it’s one that impacts everyone on the planet.

The talks ended on a hot, humid afternoon in the Zhongnanhai compound in central Beijing, which houses offices for the Politburo’s most senior members. The compound, which is heavily guarded and closed to the public, is a reminder of China’s Imperial era, with a collection of traditional pavilions scattered around three lovely lakes. Kerry met with Chinese Premier Li Keqiang in the Purple Light Pavilion, a brightly painted pagoda-style building with small porcelain animals on the corners of the roof. Li has none of the bluster – or power – of President Xi, and after exchanging greetings and thank-yous, Kerry seemed eager to hit the road. They spoke in private for a half-hour, then Kerry climbed back into his SUV, and we motorcaded back to the Marriott for a final press conference.

Within minutes, the State Department was e-mailing a list of accomplishments to reporters, including joint U.S.-China demonstration projects on smart grids, technology to capture carbon from coal plants, and new initiatives on forestry and industrial boilers. It was all both important and unimportant, small steps in a long, long march. Later, Kerry would tell me he was impressed by what he’d seen from the Chinese on climate during the trip – “There was no backsliding,” he says. Others on the U.S. team described their sense that key Chinese leaders they’d met were “extraordinarily forward-leaning.”

But huge questions still loom about how far the U.S. and China and every other big polluter on the planet will go to cut emissions. For negotiators who are pushing for a tough agreement with meaningful reductions and clear financial accounting, the biggest fear is not that the U.S. and China won’t agree on key issues, but that they will agree on too much: “We are afraid that the U.S. and China will strike a bargain that makes them both comfortable, but does little or nothing to reduce the risk of climate change,” says Mohamed Adow, senior adviser for Christian Aid, a U.K.-based relief agency that works in many developing nations. “Then the rest of the world will have to decide if they want to go along, or fight for a stronger agreement.”

A few hours later, Kerry and his team jet off to Afghanistan. The world is a big, complicated place, and everyone – even the most committed climate warriors like Kerry – has a lot of other things to think about beyond how much carbon we are dumping into the atmosphere. And that, in a way, is always the problem: There is always something more urgent, more immediately catastrophic to seize the attention of policymakers – and in the coming years, many of the crises that will distract us from dealing with the realities of climate change will largely have been caused by climate change. Through all these short-term emergencies, the Earth will keep warming, the droughts will get worse, food will grow scarce, ice will vanish, the seas will rise, and starting around 2030, climate change will emerge from the background and eventually become the only thing we talk about. It will be the story of the century.

When we get to the Marriott, I walk across the sleek marble lobby with Podesta, who looks uncharacteristically somber. Just before we step into Kerry’s press conference – where he will again underscore the importance of taking action on climate change – I ask Podesta if two days of talks with the Chinese have made him feel more hopeful about Paris next year.

“Yes,” he says. “But it’s going to be a hard road.”

The silence on climate change is deafening. It’s time for us to get loud (The Guardian)

In Dr Seuss’s parable, it take all of Whoville to make enough noise to save their planet. How much will it take to save ours?

theguardian.com, Wednesday 17 September 2014 16.43 BST

All of Dr Seuss’s children’s books – or, at least, the best ones – are sly, radical humanitarian and environmental parables. That’s why, for example, The Lorax was banned in some Pacific Northwest districts where logging was the chief economy.

Or there’s Horton Hears a Who: if you weren’t a child (or reading to a child) recently, it’s about an elephant with acute hearing who hears a cry from a dust speck. He comes to realize the dust speck is a planet in need of protection, and does his best for it.

Of course, all the other creatures mock – and then threaten – Horton for raising an alarm over something they can’t see. (Dissent is an easy way to get yourself ostracized or worse, as any feminist receiving online death threats can remind you.) And though Seuss was reportedly inspired by the situation in post-war Japan when he wrote the book, but its parable is flexible enough for our time.

You could call the scientists and the climate activists of our present moment our Hortons. They heard the cry a long time ago, and they’ve been trying to get the rest of the world to listen. They’ve had to endure attacks, mockery, and lip service … but mostly just obliviousness to what they’re saying and what it demands of us.

Recent polling data suggests most of us do want to see things change. “Two in three Americans (66%) support the Congress and president passing laws to increase energy efficiency and the use of renewable energy as a way to reduce America’s dependence on fossil fuels,” reports the US Climate Action Network. But I hear firsthand from people who aren’t particularly informed and still tell me that they are avoiding thinking about climate because it’s too late.

It is nearly too late, because we’ve know about climate change for 25 years, but the most informed scientists think that we do have a chance and some choices, if we make them now.

To listen to such scientists is an amazing and sometimes terrifying thing: they fully comprehend what systemic collapse means and where we are in that process. They – and others who pay attention to the data – see how terrible the possibilities are, but they also see the possibilities for averting the worst.

Seuss’s Horton was alone. Climate activists in the United States are a minority, but there are vast numbers of people across the world who know how serious the situation is, who are facing it and who are listening and asking for action. Some of them will be with us when the biggest climate march in history takes place on Sunday in New York City – starting on the southern edge one of the nation’s largest urban green spaces, Central Park, running around Times Square and then moving west to the Hudson River – to demand that the UN get serious with this attempt to hammer out a climate change treaty at its summit next week.

A whole lot more people are going to come together to demand that our political leaders do something about climate than have done so before. In a symbolic action, at 12:58pm local time, they will observe a collective couple of minutes of silence dedicated to the past. Wherever you are on Sunday, you can join us in observing that silence and remembering the millions displaced last year by the kinds of floods and storms that climate change augments, or the residents of island nations whose homes are simply disappearing under the waves; the small shellfish whose shells are dissolving or the species that have died out altogether; the elderly and inform who have died in our longer, hotter heatwaves or the people who died in New York’s Hurricane Sandy not quite two years ago.

At 1pm local time, we will face the future, and demand that our leaders face the music. The marchers will make two minutes of noise, and every pot-banger, church-bell-ringer, hornblower and drummer on earth is invited to join in. Churches are invited to ring their bells; synagogues to blow their shofars; mosques to use their loudspeakers; secular humanists to get their brass bands on. Get your own pots and pans, or your trumpets and whistles.

We needed someone to ring the alarm all these decades of inaction. On Sunday don’t wait to hear it from someone else: make some noise yourself. It’s time to start making the future we hope for instead of waiting for the one we fear.

I wish that I could write a pat ending for the story of how we saved the earth, but that is, so to speak, all up in the air right now.

But at the end of Horton Hears a Who, the small people of Whoville decide to make a huge roar so that everyone else could hear them: they all roar and bang and blast, but it takes a boy named Jojo (playing with his yoyo) to add his yapping voice to the roar for them to become audible.

This is our planet: our little blue sphere in the Orion Spur of the Milky Way Galaxy, with the beautifully elaborate systems of birds and insects and weather and flowering plants all working together – or that used to work together, and which are now falling apart. And it’s your voice that’s needed, so raise it on Sunday. Join the roar, so that everyone who wasn’t listening finally has to hear.

• This article was updated on 17 September 2014 to reflect that the the New York City Police Department only granted the People’s Climate March permission to march to Sixth Avenue, and not all the way to the United Nations building on First Avenue.

Brasil precisa ter sistema de monitoramento a longo prazo sobre mudanças climáticas, diz secretário (MCTI)

quarta-feira, 17 de setembro de 2014

Para Carlos Nobre, é central o país ter um conhecimento muito apurado do impacto das mudanças climáticas sobre a economia, a sociedade e o ambiente 

O secretário de Políticas e Programas de Pesquisa e Desenvolvimento do Ministério da Ciência, Tecnologia e Inovação (Seped/MCTI), Carlos Nobre, abriu nesta terça-feira (16) o workshop internacional Desafios para o Monitoramento e a Observação dos Impactos de Mudanças Climáticas, na Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), em Brasília.

Ação do projeto Diálogos Setoriais entre Brasil e União Europeia, com organização do MCTI e apoio da Embaixada Britânica, o encontro segue até amanhã (17), em busca de identificar desafios e elaborar recomendações para observar impactos de mudanças climáticas, além de induzir a formação de uma rede de pesquisadores e gestores que possa compartilhar conhecimento e contribuir para a estruturação de um sistema brasileiro de monitoramento.

“Consideramos central para o planejamento e as estratégias de desenvolvimento sustentável do Brasil nós termos um conhecimento muito apurado sobre como as mudanças climáticas estão impactando e irão impactar a economia, a sociedade e o ambiente, com ênfase na nossa imensa biodiversidade”, afirmou Nobre. “Nesse sentido, o MCTI, já há alguns anos, começou um projeto, com fundos brasileiros, para desenvolver um conceito, uma ideia, um programa, para monitorar e observar esses impactos”.

Antecipação

Na visão do secretário, estruturar um sistema seria o passo seguinte a iniciativas como a Rede Brasileira de Pesquisas sobre Mudanças Climáticas Globais (Rede Clima), estabelecida em 2008, após a publicação do 4º Relatório do Painel Intergovernamental sobre Mudanças Climáticas (IPCC, na sigla em inglês).

“A Rede Clima tem produzido uma série de resultados, muitos deles na direção de entender impactos”, disse Nobre. “A decorrência desse incipiente e novo conhecimento é ensejar o desenho de um sistema de longo prazo, de décadas de monitoramento, que nos permita nos anteciparmos, para que a sociedade não seja tomada de surpresa quando impactos de fato estiverem ocorrendo.”

O secretário lembrou que o 4º Relatório do IPCC apontou concentração na Europa, nos Estados Unidos e no Japão dos sítios observacionais com estudos de impactos das mudanças climáticas, com raros exemplos na América Latina.

“A situação mudou um pouco para melhor no 5º Relatório, divulgado neste ano, mas nenhum dos sítios apresentados localiza-se no Brasil”, comparou. “Isso já chamou a atenção, porque não temos observações sistêmicas de longo período sobre os impactos nos mais diversos setores de atividades econômicas”.

Para atingir o objetivo de contribuir para o futuro sistema, segundo Nobre, o workshop trouxe especialistas brasileiros e estrangeiros de diversos setores, como agricultura, biodiversidade, ecologia, energia, recursos hídricos, oceanos, saúde e zonas costeiras: “A discussão é muito relevante para o Brasil, porque grande parte do produto econômico do país tem a ver com recursos naturais”.

Origem

Nobre associou a complexidade do sistema à existência de vários motivos desencadeadores de mudanças climáticas. Ele citou três exemplos aplicados ao cenário nacional, divididos por origem antropogênica, local e global.

O primeiro caso diz respeito às savanas tropicais do Brasil Central, onde tradicionalmente há aumento considerável de incêndios de vegetação por ação humana de agosto a outubro, período de seca nessas regiões.

“Isso perturba muito o ambiente biológico do Cerrado, ou seja, os impactos são muito grandes na biodiversidade, mas a fumaça das queimadas também gera um grande problema de saúde pública”, alertou.

De acordo com o secretário, as chuvas na cidade de São Paulo estão entre 30% a 35% maiores, mais volumosas e mais intensas do que 100 anos atrás. “Essa é, principalmente, uma mudança climática de origem local, uma ilha urbana de calor, um impacto da urbanização”, explicou. “O atual cenário agrava a questão dos desastres naturais em uma região por onde transitam 20 milhões de pessoas”.

Acerca da origem global, Nobre cita o 5º Relatório do IPCC, publicado em 2013 e 2014. “O documento sugere, com forte embasamento científico, que a alternância de secas e inundações na Amazônia na última década já seria um resultado das mudanças climáticas globais”, disse. “Particularmente na região da floresta, nós já estamos vendo como detectar, medir e enxergar impactos, como desenhar sistemas que possam de forma precursora sinalizar grandes alterações, de modo que se permita ao setor público, e também aos setores econômicos, se precaverem e adotarem políticas de adaptação”.

Intercâmbio

Presente na abertura do workshop, a secretária de Gestão Pública do Ministério do Planejamento, Orçamento e Gestão (MPOG), Ana Lúcia Amorim, abordou o projeto Diálogos Setoriais, gerido pela pasta, que apoia a realização de estudos nas mais diversas áreas temáticas.

O diplomata português Rui Ludovino, diretor da Delegação da União Europeia no Brasil, lembrou que, desde 2007, o país é parceiro estratégico da Europa. “Temos um acordo de cooperação assinado entre as duas partes que engloba inúmeras áreas, da econômica à tecnológica, da ambiental à social”, observou.

Na opinião da diretora de Ciência e Inovação da Embaixada Britânica, Caroline Cowan, o Brasil inova ao propor a criação de uma rede de monitoramento e observação. “Até agora, não temos no mundo um sistema assim. Vamos ver como podemos trabalhar juntos para estabelecê-lo. Em adaptação a mudanças climáticas, já atuamos bastante com a União Europeia e o Brasil”.

Os debates do workshop devem gerar um documento de recomendações. Entre os palestrantes, estão pesquisadores dos institutos nacionais de Pesquisas Espaciais (Inpe/MCTI) e de Pesquisas da Amazônia (Inpa/MCTI), do Centro de Tecnologia da Informação Renato Archer (CTI/MCTI) e do Centro Comum de Pesquisa da Comissão Europeia (JRC, na sigla em inglês).

Cúpula do Clima da ONU: só teatro ou fatos concretos? (IPS)

17/9/2014 – 01h38

por Thalif Deen, da IPS

cumbreclima Cúpula do Clima da ONU: só teatro ou fatos concretos?

Nações Unidas, 17/9/2014 – A tão comentada Cúpula do Clima, que acontecerá no final deste mês, é apresentada como um dos grandes acontecimentos político-ambientais da Organização das Nações Unidas (ONU) para 2014. Seu secretário-geral, Ban Ki-moon, pediu aos mais de 120 governantes e empresários que participarão da cúpula de um único dia, 23 de setembro, que anunciem iniciativas significativas e substanciais, com promessas de fundos incluídas, “para ajudar o mundo a avançar por um caminho que limite o aquecimento global”.

Segundo a ONU, a cúpula será a primeira ocasião em cinco anos em que os líderes do mundo se reunirão para discutir o que se classifica de desastre ecológico: a mudança climática. Entre as repercussões negativas do aquecimento global estão a elevação do nível do mar, padrões climáticos extremos, acidificação dos oceanos, derretimento de geleiras, extinção de espécies da biodiversidade e ameaças à segurança alimentar mundial, alerta a organização.

Mas o que se pode esperar realmente da conferência deste mês, que provavelmente não durará mais do que 12 horas?

“Um acontecimento de um dia não poderá nunca resolver tudo o que se relaciona com a mudança climática, mas pode ser um ponto de inflexão para demonstrar renovada vontade política de agir”, opinou Timothy Gore, diretor de políticas e pesquisa da campanha Crecede Oxfam International. Alguns líderes políticos aproveitarão a ocasião para fazer isso, mas muitos “parecem decididos a se manterem afastados dos compromissos transformadores necessários”, acrescentou.

Segundo Gore, a cúpula foi pensada como uma plataforma para os novos compromissos de ação em matéria climática, mas existe o risco real de estes não serem grande coisa. “O enfoque colocado nas iniciativas voluntárias em lugar dos resultados negociados significa que não há garantias de que os anúncios que forem feitos na cúpula serão suficientemente sólidos”, acrescentou.

Espera-se que o Fundo Verde para o Clima mobilize cerca de US$ 100 bilhões anuais no Sul em desenvolvimento até 2020, segundo a ONU, mas este ainda não recebeu os fundos que serão entregues aos países em desenvolvimento para que possam implantar suas ações climáticas.

“No dia 23 de setembro veremos como os líderes mundiais não estão à altura do que necessitamos para lidar com a perigosa mudança climática”, apontou à IPS Dipti Bhatnagar, da Amigos da Terra Internacional e da Justiça Ambiental, de Moçambique. As “promessas” que os governos e as empresas farão na Cúpula do Clima serão extremamente insuficientes para abordar a catástrofe climática, ressaltou a ativista.

“A ideia de os governantes assumirem compromissos voluntários e não vinculantes é um insulto para centenas de milhares de pessoas que morrem a cada ano pelos impactos da mudança climática”, afirmou Bhatnagar. “Necessitamos que os países industrializados assumam objetivos de redução de emissões equitativos, ambiciosos e vinculantes, não um desfile de governantes que querem causar boa impressão. Mas este desfile falso é só o que vamos ver nesta cúpula de um dia”, opinou.

No dia 21, dois dias antes da cúpula, centenas de milhares de pessoas farão uma manifestação contra a mudança climática em cidades de todo o mundo. “Nesse dia, estaremos nas ruas de Nova York como parte da maior marcha climática na história, que enviará uma mensagem forte e clara para que os líderes mundiais ajam agora”, explicou Martin Kaiser, líder do projeto Política Climática Mundial, do Greenpeace.

Kaiser sugeriu que as empresas devem anunciar datas concretas a partir das quais operarão com 100% de energia renovável. Além disso, “os governos devem se comprometer a eliminar gradualmente os combustíveis fósseis até 2050 e tomar medidas concretas, como acabar com o financiamento das centrais elétricas movidas a carvão”, destacou. “Também esperamos que os governos anunciem dinheiro novo e adicional para o Fundo Verde para o Clima, a fim de ajudar os países vulneráveis a se adaptarem aos desastres climáticos”, afirmou.

“Precisamos que o Norte industrial entregue fundos públicos seguros, previsíveis e obrigatórios ao Sul em desenvolvimento por intermédio do sistema da ONU”, disse Bhatnagar, da Amigos da Terra Internacional. Os líderes dos países industrializados estão descuidando de sua responsabilidade para evitar as catástrofes climáticas, impulsionados pelos estreitos interesses econômicos e financeiros das elites ricas, da indústria dos combustíveis fósseis e das corporações transnacionais, acrescentou.

“O que se necessita para deter a mudança climática são objetivos de redução de emissões equitativos, ambiciosos e vinculantes dos países desenvolvidos, junto com a transferência de fundos e tecnologia aos países em desenvolvimento. Também precisamos de uma completa transformação de nossos sistemas de energia e alimentos”, enfatizou Bhatnagar.

Nesse sentido, é preciso maior transparência para decidir se os anúncios feitos são coerentes com as últimas conclusões científicas sobre o clima e se protegem os interesses dos mais vulneráveis diante dos impactos climáticos, detalhou Gore. Com relação ao papel do setor privado, “precisamos que os empresários combatem a mudança climática, e estão surgindo bons exemplos de empresas que estão à altura da ocasião”, acrescentou .

No setor de alimentos e bebidas, por exemplo, a Oxfam trabalhou com companhias como Kellogg e General Mills para que estas assumam compromissos de redução das emissões de suas cadeias de fornecimento agrícola, extremamente contaminantes. “Mas, em geral, essa cúpula mostra que há muitas partes do setor privado que ainda não estão à altura, já que as iniciativas que serão apresentadas não cumprem com a  transformação que precisamos”, destacou Gore.

“Isso serve para recordarmos a importância fundamental que tem a forte liderança governamental na mudança climática. As iniciativas voluntárias de baixo para cima não são um substituto da ação real do governo”, afirmou Gore. Envolverde/IPS

When their research has social implications, how should climate scientists get involved? (The Guardian)

Scientists prefer to stick to research, but sometimes further involvement is warranted

Thursday 4 September 2014 14.00 BST

First, at the end of this post is a question to my readers wherein I ask for feedback. So, please read to the end.

Most scientists go into their studies because they want to understand the world. They want to know why things happen; also how to describe phenomena, both mathematically and logically. But, as scientists carry out their research, often their findings have large social implications. What do they do when that happens?

Well traditionally, scientists just “stick to the facts” and report. They try to avoid making recommendations, policy or otherwise, that are relevant to the findings. But, as we see the social implications of various issues grow larger (environmental, energy, medical, etc.) it becomes harder for scientists to sit out in more public discussions about what should be done. In fact, researchers who have a clear handle on the issue and the pros and cons of different choices have very valuable perspectives to provide society.

But what does involvement look like? For some scientists, it may be helping reporters gather information for stories that may appear online, in print, radio, or television. In another manifestation, it might be writing for themselves (like my blog here at the Guardian). Others may write books, meet with legislators, or partake in public demonstrations.

Each of these levels of engagement has professional risks. We scientists need to protect our professional reputations. That reputation requires that we are completely objective in our science. As a scientist becomes more engaged in advocacy, they risk being viewed by their colleagues as non-objective in their science.

Of course, this isn’t true. It is possible (and easy) to convey the science but also convey the importance of taking action. I do this on a daily basis. But I will go further here. It is essential for scientists to speak out. With the necessary expertise to make informed decisions, it is out obligation to society. Of course, each scientist has to decide how to become engaged. We don’t get many kudos for engagement, it takes time and money out of our research, you will never get tenured for having a more public presence, and you will likely receive po)rly-writen hate mail – but it still is needed for informed decision making.

One very public activity some scientists engage in is public events and demonstrations. A large such event is going to occur this September in New York (September 21 – the Peoples’ Climate March). Just a few days before the UN Climate Summit, the Climate March hopes to bring thousands of people from faith, business, health, agriculture, and science communities together. Scientists will certainly be there – and those scientists should be lauded. I am encouraging my colleagues to participate in events like this.

Okay so now the poll (sort of). I have been writing this blog for over a year – something like 60 posts. Approximately half those posts are on actual science, breaking new studies that shed light on our ever expanding understanding of the Earth’s climate. Another sizeable number of posts are on reviews of books, movies, projects, and others. A third category deals with how climate impacts different locations around the globe. In this group, I’ve written about climate change in Uganda, Kenya, and Cameroon – climate change effects that I’ve witnessed with my own eyes. A fourth category that I just started focuses on specific scientists telling how they got into climate change. Finally, I write a few posts on debunking bad science and misguided public statements.

In truth, I prefer the harder science, but frankly these do not get as many page views as the debunking posts. I am here asking for suggested topics of future posts. I have a few in queue but I always look for engaging topics and angles. You can send them to me at my university email address,jpabraham@stthomas.edu. Also, feel free to comment on the current mix of stories. Is 50% hard science the right mix? Is it too much? Too little? Is my writing to technical? Not technical enough? Let me hear your thoughts.

Can Carbon Capture Technology Be Part of the Climate Solution? (Environment 360)

08 SEP 2014

Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels.

by david biello

For more than 40 years, companies have been drilling for carbon dioxide in southwestern Colorado. Time and geology had conspired to trap an enormous bubble of CO2 that drillers tapped, and a pipeline was built to carry the greenhouse gas all the way to the oil fields of west Texas. When scoured with the CO2, these aged wells gush forth more oil, and much of the CO2 stays permanently trapped in its new home underneath Texas.

More recently, drillers have tapped the Jackson Dome, nearly three miles beneath Jackson, Mississippi, to get at a trapped pocket of CO2 for similar

use. It’s called enhanced oil recovery. And now there’s a new source of CO2 coming online in Mississippi — a power plant that burns gasified coal in Kemper County, due to be churning out electricity and captured CO2 by 2015 and sending it via a 60-mile pipeline to oil fields in the southern part of the state.

The Mississippi project uses emissions from burning a fossil fuel to help bring more fossil fuels out of the ground — a less than ideal solution to the problem of climate change. But enhanced oil recovery may prove an important step in making more widely available a technology that could be critical for combating climate change — CO2 capture and storage, or CCS.

As the use of coal continues to grow globally — coal consumption is expected to double from 2000 to 2020 largely due to demand in China and India — some scientists believe the widespread adoption of CCS technology could be key to any hope of limiting global average temperature increase to 2 degrees Celsius, the threshold for avoiding major climate disruption. After all, coal is the dirtiest fossil fuel.

“Fossil fuels aren’t disappearing anytime soon,” says John Thompson, director of the Fossil Fuel Transition Project for the non-profit Clean Air Task Force. “If we’re serious about preventing global warming, we’re going to have to find a way to use those fuels without the carbon going into the atmosphere. It seems inconceivable that we can do that without a significant amount of carbon capture and storage. The question is how do we deploy it in time and in a way that’s cost-effective across many nations?”

The biggest challenge is one of scale, as the potential demand from aging oil fields for CO2 produced from coal-fired power plants is enormous. Thompson estimates that enhanced oil recovery could ultimately consume 33 billion metric tons of CO2 in total, or the equivalent of all the CO2 pollution from all U.S. power plants for several decades. Thompson and other analysts view such large-scale enhanced oil recovery as an important phase in the deployment of CCS technology while replacements for fossil fuels are developed. 

“In the short term, in order to develop the technology, we probably will enable more use of hydrocarbons, which makes environmentally conscious people uncomfortable,” says Chris Jones, a chemical engineer working on CO2 capture at the Georgia Institute of Technology. “But it’s a necessary thing we have to do to get the technology out there and learn how to make it more efficient.”

At the same time, CO2 capture and storage is not as simple as locking away carbon deep underground. As Jones notes, the process will perpetuate fossil fuel use and may prove a wash as far as keeping global warming pollution out of the atmosphere. Then there are the risks of human-caused earthquakes as a result of pumping high-pressure liquids underground or accidental releases as all that CO2 finds its way back to the atmosphere.

“Any solution that doesn’t take carbon from the air is, in principle, not sustainable,” says physicist Peter Eisenberger of the Lamont-Doherty Earth Observatory at Columbia University, who is working on methods to pull CO2 out of the sky rather than smokestacks. He notes that merely avoiding CO2 pollution is not enough and will create political powerhouses—heirs to the energy companies of today—that will entrench such unsustainable technologies “Why spend so much time and energy and ingenuity coming up with solutions that are not really solutions?” he adds.

But the expansion of enhanced oil recovery remains the main front in an intensifying effort to more broadly adopt CCS technology and reduce its price, which is currently the major impediment to its deployment. The need for CO2 storage goes beyond China and the U.S., the world’s two largest polluters. Worldwide, more than 35 billion metric tons of CO2 are being dumped into the atmosphere annually, almost all from the burning of coal, oil, and natural gas. To restrain global warming to the 2 degree C target, more than 100 CCS projects eliminating 270 million metric tons of CO2 pollution annually would have to be built by 2020, according to theInternational Energy Agency. But only 60 are currently planned or proposed and just 21 of those are actually built or in operation.

Those include the Kemper facility and other coal-fired power plants, but also a CCS project under construction at an ethanol refinery in Illinois. A group led by Royal Dutch Shell is building technology to capture the CO2 pollution from tar sands operations in Alberta, Canada, and in Saskatchewan, a $1.2 billion project to retrofit a large coal-fired power plant with CCS technology is expected to open later this year. And there are 34 proposed or operating CCS projects outside of North America, the majority in Asia and Australia. But European countries like Germany have rolled back plans to adopt CCS because of public opposition, dropping the number of European projects from 14 planned in 2011 to just five as of 2014, according to the Global CCS Institute. 

That might conflict with the European Union’s avowed intention to help combat climate change. The U.N. Intergovernmental Panel on Climate Change suggested earlier this year that carbon capture and storage at power plants could prove a critical part of any serious effort to restrain global warming. “We depend on removing large amounts of CO2 from the atmosphere in order to bring concentrations well below 450 [parts-per-million] in 2100,” said Ottmar Edenhofer, an economist at the Potsdam Institute for Climate Impact Research and co-chair of the IPCC’s third working group, which was tasked with figuring out ways to mitigate climate change. Ultimately, he said, keeping a global temperature rise to 2 degrees without any CCS would require phasing out fossil fuels entirely within “the next few decades.”

Yet, from 2007 to 2013, global coal consumption increased from 6.4 billion to 7.4 billion metric tons, and coal use continues to rise. Although renewable energy sources like solar and wind are growing rapidly, they are doing so from a very small base and many energy analysts argue that it will be decades before they can supplant fossil fuels. The time and expense of building nuclear power plants — and public opposition — has also hampered that low-carbon technology’s ability to replace coal burning. And biofuels or electric cars remain a long way from supplanting oil for transportation.

The Obama administration hopes to encourage the development of CO2 capture and use or storage. New rules from the Environmental Protection Agency requiring a 30 percent cut in power plant emissions by 2030 may spur development of CCS technologies. Already, NRG Energy has partnered with a Japanese firm to add CO2 capture to a coal-fired power plant near Houston and use a pipeline to send the captured pollution to nearby oilfields. Dubbed Petra Nova, the $1 billion CCS project is the latest in a series of 19 CO2 capture projects underway or proposed in the U.S. 

The bulk of such CO2 capture and storage experiments may soon shift to China, the world’s largest emitter of CO2. The Chinese and U.S. governments have a cooperative agreement to develop the technology, including partnerships between Chinese power companies like Huaneng and American corporations such as Summit Power, which is developing a CCS power plant in west Texas. In China, the long-awaited GreenGen power plant in Tianjin is still under construction and will capture CO2 for China’s own efforts at enhanced oil recovery. But going forward, the expense of CCS may make the technology even more unpalatable in a developing country like China, which also has plans to turn coal into liquid fuels — a process that, from a climate perspective, is even worse than burning the dirty rock directly.

The technology to capture CO2 is relatively simple, and has been in use since the 1930s. For example, CO2 can be captured from the smokestacks of coal plants, natural gas plants, and even factories by routing the flue gases through an amine chemical bath, which binds the CO2. The chemical is then heated to release the CO2. The CO2 is pressurized to convert it to a liquid, and the liquid is then pumped via pipeline to an appropriate storage site. Those include underground geological formations, such as sandstones or saline aquifers, but also old oil fields, where the CO2 replaces the oil in small pores in the rock left behind by conventional methods and forces it up to the surface. Six percent of U.S. oil already comes from usingenhanced oil recovery, a number that will increase, according to the U.S. Energy Information Administration.

Still, the economic and technological challenges facing CCS are daunting. Much-heralded projects like the CO2 capture and storage demonstration at the Mountaineer Power Plant in West Virginia were abandoned because no one wanted to pay for it. The hardware sits unused next to the hulking power plant’s smokestacks and cooling towers. 

The ultimate challenge is that capturing CO2 from a smokestack costs more than simply dumping it into the atmosphere. Analysts say the simplest way to encourage less pollution and more CO2 capture would be to charge for the privilege of emitting CO2 by imposing a tax on carbon emissions. A price on CO2, if high enough, might make capturing the greenhouse gas look cheap.

Even if that policy change happens, the problem of storing all that CO2 remains, including concerns that the CO2 could escape back into the atmosphere or cause earthquakes. In Algeria, a test to store nearly 4 million metric tons of injected CO2 underground was halted after the gas raised the overlying rock and fractured it. Concerns over such induced seismicity or accidental releases of CO2 have blocked CCS plans in Europe, as have concerns over how to ensure the stored CO2 stays put for millennia.

But storing CO2 underground can work, as Norway’s Sleipner project in the North Sea has demonstrated. At Sleipner, which started capturing and storing CO2 in 1996, more than 16 million metric tons of CO2 have been put in an undersea sandstone formation; the project is funded by Norway’s carbon tax. And around the world, the potential storage resource is gargantuan. The U.S. alone has an estimated 4 trillion metric tons of CO2 storage capacity in the form of porous sandstones or saltwater aquifers, according to the U.S. Department of Energy.

Scientists at Columbia’s Lamont-Doherty Earth Observatory and elsewhere are investigating just how vast the storage potential under the ocean could be. David Goldberg, a marine geophysicist at Lamont, proposes that liquid CO2 could be pumped offshore and injected into the ubiquitous basalt formations found off many of the world’s coastlines. When mixed with water, the CO2 leaches metals out of the basalt and forms a carbonate chalk, Goldberg explains. 

“The goal of the whole CCS exercise is to take CO2, which is volatile, and put it in solid form where it will stay locked away forever,” he adds. Goldberg has calculated that just one such ridge site that runs the north-south length of the Atlantic Ocean could theoretically store all of humanity’s excess CO2 emissions to date. “The magic of being offshore is that you are away from people and away from property.”

There is also basalt on land. In an experiment in Iceland, more than 80 percent of the injected CO2 interacted with the surrounding basalt and converted to rock in less than a year. A similar experiment in Washington State achieved similar results.

In the end, getting off fossil fuels entirely is the only way to control CO2 pollution. But until that happens, CCS could be vital to stave off catastrophic climate change. “Ultimately, we need a thermostat on this planet,” says Klaus Lackner, a Columbia University physicist who is working on pulling the greenhouse gas directly out of the air rather than capturing it from smokestacks. “And we need to control the CO2.”

Correction, September 9, 2014: Previous versions of this article misstated the amount of CO2 storage capacity in porous sandstones or saltwater aquifers in the U.S.; it is 4 trillion metric tons.

World on track to be 4C warmer by 2100 because of missed carbon targets (The Guardian)

Concerns about the short term costs and impacts of investment to address risks is paralysing action on climate changeJonathan Grant

Guardian Professional, Monday 8 September 2014 13.28 BSTHeavy rains in Albuquerque, New Mexico

Global ambitions to reduce emissions are becoming a bit like the resolutions we make to give something up at new year: the intention is sincere, but we don’t always deliver.For the sixth successive year of the PwC Low Carbon Economy Index, the global carbon target has been missed. And inadequate action today means that even steeper reductions are needed in the future. The target is based on projections of economic growth and the global carbon budget set out by the Intergovernmental Panel on Climate Change (IPCC) which gives a reasonable probability of limiting warming to 2C.

Globally, annual reductions need to be five times current levels, averaging 6.2% a year, every year from now to 2100, compared with 1.2% today. At the national level, Australia is at the top of our decarbonisation league of G20 nations, followed by the UK. Both countries had a strong increase in renewable generation, albeit from a low base, combined with slight a reduction in coal use. The US was nearer the bottom as coal use bounced back, retaking a share of the electricity mix from shale gas.

The world is currently on track to burn this century’s IPCC carbon budget within 20 years, and a pathway to 4C of global warming by 2100. For many of us, 2034 is within our working lifetime. It’s within the timeframe of decisions being made today, on long-term investments, on the location of factories and their supply chains. So businesses are making those decisions faced with uncertainty about climate policy and potential impacts of climate change.

It is clear that the gap between what governments are saying about climate change and what they are doing about it continues to widen. While they talk about two degrees at the climate negotiations, the current trend is for a 4C world.

There is little mention of these two degrees of separation in the negotiations, in policy documents, in business strategies or in board rooms. Operating in a changing climate is becoming a very real challenge for UK plc. Some of the biggest names in business are mapping the risks posed by a changing climate to their supply chain, stores, offices and people.

But while the findings question the reality of the 2C target in negotiations, consider two situations in the analysis that demonstrates the strong case for the negotiations’ role in focusing everyone on co-ordinated action on climate change.

First, our analysis shows that the top 10 destinations for the UK’s foreign direct investment in 2011 were exposed to almost $100bn worth of extreme weather losses in 2013. Multi-billion pound UK investments are wrapped up in transport, technology, retail, food and energy sectors, making this an issue on everyone’s doorstep.

Second, co-ordinated, ambitious action to tackle emissions growth should protect business in the long term. It could even be a boost to growth. It would avoid inevitable short-term decisions that may look attractive, such as shutting down a steel operation in a country with a high cost of carbon to move it to another with a lower cost, but merely relocate emissions. And take jobs with them.

The concern about short-term costs and impacts on investment is paralysing our ability to address the long-term climate risks. Perhaps competitiveness is the new climate scepticism. Businesses call for a level playing field on carbon pricing, when it should be seen in the wider context of labour and energy prices, the skills market and wider legislative environment.

There’s a danger when we talk in small numbers – whether they are one or two degrees, or the 6% now required in annual decarbonisation (every year for the next 66 years, by the way), that they sound manageable. The 6% figure is double the rate the UK achieved when we dashed for gas in the 1990s. A shale gas revolution might help, but would need to be accompanied by a revolution in carbon capture and storage and revolutions in renewables, in electric transport, in industrial processes and in our buildings.

The UK’s results are encouraging, even if they fall short of the overall target necessary. Leadership in low carbon for the UK is down in part to policies and investment, partly the structure of our economy, and partly traditional factors such as skills and education. But it’s notable that while the Low Carbon Economy Index shows that the UK’s carbon intensity is lower than many, it is still higher than in France, Argentina or Brazil. It’s a neat encapsulation of a view of the world through a low carbon economy lens, not just a GDP one. The UK’s competitiveness or attractiveness today needs investment to hold on to it for tomorrow.

World falls behind in efforts to tackle climate change: PwC (Reuters)

LONDON Sun Sep 7, 2014 6:24pm EDT

(Reuters) – The world’s major economies are falling further behind every year in terms of meeting the rate of carbon emission reductions needed to stop global temperatures from rising more than 2 degrees this century, a report published on Monday showed.

The sixth annual Low Carbon Economy Index report from professional services firm PwC looked at the progress of major developed and emerging economies toward reducing their carbon intensity, or emissions per unit of gross domestic product.

“The gap between what we are achieving and what we need to do is growing wider every year,” PwC’s Jonathan Grant said. He said governments were increasingly detached from reality in addressing the 2 degree goal.

“Current pledges really put us on track for 3 degrees. This is a long way from what governments are talking about.”

Almost 200 countries agreed at United Nations climate talks to limit the rise in global temperatures to less than 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times to limit heat waves, floods, storms and rising seas from climate change. Temperatures have already risen by about 0.85 degrees Celsius.

Carbon intensity will have to be cut by 6.2 percent a year to achieve that goal, the study said. That compares with an annual rate of 1.2 percent from 2012 to 2013.

Grant said that to achieve the 6.2 percent annual cut would ‎require changes of an even greater magnitude than those achieved by recent major shifts in energy production in some countries.

France’s shift to nuclear power in the 1980s delivered a 4 percent cut, Britain’s “dash for gas” in the 1990s resulted in a 3 percent cut and the United States shale gas boom in 2012 led to a 3.5 percent cut.

GLIMMER OF HOPE

PwC said one glimmer of hope was that for the first time in six years emerging economies such as China, India and Mexico had cut their carbon intensity at a faster rate than industrialized countries such as the United States, Japan and the European Union.

As the manufacturing hubs of the world, the seven biggest emerging nations have emissions 1.5-times larger than those of the seven biggest developed economies and the decoupling of economic growth from carbon emissions in those nations is seen as vital.

Australia had the highest rate of decarbonization for the second year in a row, cutting its carbon intensity by 7.2 percent over 2013.

Coal producer Australia has one of the world’s highest rates of emissions per person but its efforts to rein in the heat-trapping discharges have shown signs of stalling since the government in July repealed a tax on emissions.

Britain, Italy and China each achieved a decarbonization rate of 4-5 percent, while five countries increased their carbon intensity: France, the United States, India, Germany and Brazil.

It is widely acknowledged that the planet’s political leaders and its people are currently failing to take enough action to prevent catastrophic climate change.

Next year, at the United Nations climate change conference in Paris, representatives of all the world’s countries will be hoping to reach a new deal to cut greenhouse gases and prevent the planet overheating dangerously. So far, there are no signs that their leaders have the political will to do so.

To try to speed up the process, the UN secretary general, Ban Ki-moon, has invited world leaders to UN headquarters in New York on 23 September for a grandly-named Climate Summit 2014.

He said at the last climate conference, in Warsaw last year, that he is deeply concerned about the lack of progress in signing up to new legally-binding targets to cut emissions.

If the summit is a success, then it means a new international deal to replace the Kyoto protocol will be probable in late 2015 in Paris. But if world leaders will not accept new targets for cutting emissions, and timetables to achieve them, then many believe that political progress is impossible.

Ban Ki-moon’s frustration about lack of progress is because politicians know the danger we are in, yet do nothing. World leaders have already agreed that there is no longer any serious scientific argument about the fact that the Earth is heating up and if no action is taken will exceed the 2C danger threshold.

It is also clear, Ban Ki-moon says, that the technologies already exist for the world to turn its back on fossil fuels and cut emissions of greenhouse gases to a safe level.

What the major countries cannot agree on is how the burden of taking action should be shared among the world’s 196 nations.

Ban Ki-moon already has the backing of more than half the countries in the world for his plan. These are the most vulnerable to climate change, and most are already being seriously affected.

More than 100 countries meeting in Apia, Samoa, at the third UN conference on small island developing states, in their draft final statement, note with “grave concern” that world leaders’ pledges on the mitigation of greenhouse gases will not save them from catastrophic sea level rise, droughts, and forced migration. “We express profound alarm that emissions of greenhouse gases continue to rise globally.”

Many of them have long advocated a maximum temperature rise of 1.5C to prevent disaster for the most vulnerable nations, such as the Marshall Islands and the Maldives.

The draft ministerial statement says: “Climate change is one of the greatest challenges of our time, and we express profound alarm that emissions of greenhouse gases continue to rise globally.

“We are deeply concerned that all countries, particularly developing countries, are vulnerable to the adverse impacts of climate change and are already experiencing an increase in such impacts, including persistent drought and extreme weather events, sea level rise, coastal erosion and ocean acidification, further threatening food security and efforts to eradicate poverty and achieve sustainable development.”

Speaking from Apia, Shirley Laban, the convenor of the Pacific Islands Climate Action Network, an NGO, said: “Unless we cut emissions now, and limit global warming to less than 1.5C, Pacific communities will reap devastating consequences for generations to come. Because of pollution we are not responsible for, we are facing catastrophic threats to our way of life.”

She called on all leaders attending the UN climate summit in New York to “use this historic opportunity to inject momentum into the global climate negotiations, and work to secure an ambitious global agreement in 2015”.

This is a tall order for a one-day summit, but Ban Ki-moon is expecting a whole series of announcements by major nations of new targets to cut greenhouse gases, and timetables to reach them.

There are encouraging signs in that the two largest emitters – China and the US – have been in talks, and both agree that action is a must. Even the previously reluctant Republicans in America now accept that climate change is a danger.

It is not yet known how many heads of state will attend the summit in person, or how many will be prepared to make real pledges.

At the end of the summit, the secretary general has said, he will sum up the proceedings. It will be a moment when many small island states and millions of people around the world will be hoping for better news.

Activists promise biggest climate march in history (The Guardian)

People’s Climate March in New York and cities worldwide hopes to put pressure on heads of state at Ban Ki-moon summit

Hundreds of thousands of people are expected to take to the streets of New York, London and eight other cities worldwide in a fortnight to pressure world leaders to take action on global warming, in what organisers claim will be the biggest climate march in history.

On 23 September, heads of state will join a New York summit on climate change organised by Ban Ki-moon, the first time world leaders have come together on the issue since the landmark Copenhagen summit in 2009, which was seen as a failure.

The UN secretary general hopes the meeting will inject momentum into efforts to reach a global deal on cutting greenhouse gas emissions by the end of 2015, at a conference in Paris.

Ricken Patel, executive director of digital campaign group Avaaz, one of the organisers of the People’s Climate March on 21 September, said the demonstration was intended to send a signal to those world leaders, who are expected to include David Cameron and Barack Obama, though not heads of state from China and India.

“We in the movement, activists, have failed up until this point to put up a banner and say if you care about this, now is the time, here is the place, let’s come together, to show politicians the political power that is out there on there. Our goal is to mobilise the largest climate change mobilisation in history and the indications are we’re going to get there,” he told the Guardian.

Patel said he expects more than a hundred thousand people at the New York march alone, which will be the focus of the day’s events. Although many of the hundreds of organisations that have committed to taking part are environmental groups, he said not all those attending would be traditional ‘green’ activists.

“There’s a very strong range and diversity of people from all walks of life, including immigrant rights groups, social justice groups. Whoever you are and wherever you are, climate change threatens us all so it brings us together.”

Nearly 400,000 have signed a call on Avaaz’s site, saying they will attend one of the global events, which also include marches in Berlin, Paris, Delhi, Rio and Melbourne.

Patel added: “We’re building for the longterm here. This is about launching a movement that can literally save the world over the longterm. We want to build to last. We recognise that at this stage what needs be done is build political momentum behind this issue – our governments are nowhere near even the planning to reach the agreements needed to keep warming below [temperature rises of] 2C.”

Around 500 adverts will appear on the London tube network from Monday, calling on people to join the march, and advertising has already appeared across the New York subway. In Rio, the organisers have permission to project messages about the march on to the statue of Christ.

In an open letter to be published this week, environment and development groups including Greenpeace, Oxfam and WWF, plus politicians including Green party MP Caroline Lucas and Labour MP Tom Watson, have joined with trade unions and faith groups to call on world leaders to use the UN summit to take action on climate change.

“Politicians all over the world cite a lack of public support as a reason not to take bold action against climate change. So on 21 September we will meet this moment with unprecedented public mobilisations in cities around the world, including thousands of people on the streets of London.

“Our goal is simple – to demonstrate the groundswell of demand that exists for ambitious climate action,” they write.

Celebrities backing the People’s Climate March include model Helena Christensen, musician Peter Gabriel, actor Susan Sarandon, Argentine footballer Lionel Messi and actor Edward Norton.

The previous biggest assembly for a climate march was in Copenhagen in 2009, when tens of thousands of people took to the streets.

Separately on Monday, NGOs Greenpeace, WWF, Green Alliance, RSPB and Christian Aid published a report, Paris 2015: Getting a global agreement on climate change, laying out the level of ambition required for a deal at the UN climate talks in Paris.

Matthew Spencer, Green Alliance’s director, said: “There is a fashionable pessimism about multilateralism which shields people from disappointment but does nothing to protect us from the insecurity that climate change is bringing. Only a strong international agreement can avoid that and give nation states the confidence that they will not be alone as they decarbonise their energy systems.”

How conversion of forests to cropland affects climate (Science Daily)

Date: September 8, 2014

Summary: The conversion of forests into cropland worldwide has triggered an atmospheric change to emissions of biogenic volatile organic compounds that — while seldom considered in climate models — has had a net cooling effect on global temperatures, according to a new study.

The conversion of forests into cropland worldwide has triggered an atmospheric change that, while seldom considered in climate models, has had a net cooling effect on global temperatures, according to a new Yale study.

Writing in the journal Nature Climate Change, Professor Nadine Unger of the Yale School of Forestry & Environmental Studies (F&ES) reports that large-scale forest losses during the last 150 years have reduced global emissions of biogenic volatile organic compounds (BVOCs), which control the atmospheric distribution of many short-lived climate pollutants, such as tropospheric ozone, methane, and aerosol particles.

Using sophisticated climate modeling, Unger calculated that a 30-percent decline in BVOC emissions between 1850 and 2000, largely through the conversion of forests to cropland, produced a net global cooling of about 0.1 degrees Celsius. During the same period, the global climate warmed by about 0.6 degrees Celsius, mostly due to increases in fossil fuel carbon dioxide emissions.

According to her findings, the climate impact of declining BVOC emissions is on the same magnitude as two other consequences of deforestation long known to affect global temperatures, although in opposing ways: carbon storage and the albedo effect. The lost carbon storage capacity caused by forest conversion has exacerbated global warming. Meanwhile, the disappearance of dark-colored forests has also helped offset temperature increases through the so-called albedo effect. (The albedo effect refers to the amount of radiation reflected by the surface of the planet. Light-colored fields, for instance, reflect more light and heat back into space than darker forests.)

Unger says the combined effects of reduced BVOC emissions and increased albedo may have entirely offset the warming caused by the loss of forest-based carbon storage capacity.

“Land cover changes caused by humans since the industrial and agricultural revolutions have removed natural forests and grasslands and replaced them with croplands,” said Unger, an assistant professor of atmospheric chemistry at F&ES. “And croplands are not strong emitters of these BVOCs — often they don’t emit any BVOCs.”

“Without doing an earth-system model simulation that includes these factors, we can’t really know the net effect on the global climate. Because changes in these emissions affect both warming and cooling pollutants,” she noted.

Unger said the findings do not suggest that increased forest loss provides climate change benefits, but rather underscore the complexity of climate change and the importance of better assessing which parts of the world would benefit from greater forest conservation.

Since the mid-19th century, the percentage of the planet covered by cropland has more than doubled, from 14 percent to 37 percent. Since forests are far greater contributors of BVOC emissions than crops and grasslands, this shift in land use has removed about 30 percent of Earth’s BVOC sources, Unger said.

Not all of these compounds affect atmospheric chemistry in the same way. Aerosols, for instance, contribute to global “cooling” since they generally reflect solar radiation back into space. Therefore, a 50 percent reduction in forest aerosols has actually spurred greater warming since the pre-industrial era.

However, reductions in the potent greenhouse gases methane and ozone — which contribute to global warming — have helped deliver a net cooling effect.

These emissions are often ignored in climate modeling because they are perceived as a “natural” part of Earth system, explained Unger. “So they don’t get as much attention as human-generated emissions, such as fossil fuel VOCs,” she said. “But if we change how much forest cover exists, then there is a human influence on these emissions.”

These impacts have also been ignored in previous climate modeling, she said, because scientists believed that BVOC emissions had barely changed between the pre-industrial era and today. But a study published last year by Unger showed that emissions of these volatile compounds have indeed decreased. Studies by European scientists have produced similar results.

The impact of changes to ozone and organic aerosols are particularly strong in temperate zones, she said, while methane impacts are more globally distributed.

The sensitivity of the global climate system to BVOC emissions suggests the importance of establishing a global-scale long-term monitoring program for BVOC emissions, Unger noted.

No more pause: Warming will be non-stop from now on (New Scientist)

18:00 31 August 2014 by Michael Slezak

Enjoy the pause in global warming while it lasts, because it’s probably the last one we will get this century. Once temperatures start rising again, it looks like they will keep going up without a break for the rest of the century, unless we cut our greenhouse gas emissions.

The slowdown in global warming since 1997 seems to be driven by unusually powerful winds over the Pacific Ocean, which are burying heat in the water. But even if that happens again, or a volcanic eruption spews cooling particles into the air, we are unlikely to see a similar hiatus, according to two independent studies.

Masahiro Watanabe of the University of Tokyo in Japan and his colleagues have found that, over the past three decades, the natural ups and downs in temperature have had less influence on the planet’s overall warmth. In the 1980s, natural variability accounted for almost half of the temperature changes seen. That fell to 38 per cent in the 1990s and just 27 per cent in the 2000s.

Instead, human-induced warming is accounting for more and more of the changes from year to year, says Watanabe. With ever-faster warming, small natural variations have less impact and are unlikely to override the human-induced warming.

“The implication is that we will get fewer hiatus periods, or hiatus periods that last for a shorter period,” says Wenju Cai at the CSIRO in Melbourne, Australia, who wasn’t involved in the work.

Stop it

According to another recent study, the current hiatus may be our last for a while. Matthew England and his colleagues at the University of New South Wales in Sydney, Australia, tried to quantify the chance of another pause. “It’s looking to us that it’s probably going to be the last one that we’ll see in the foreseeable future,” says England.

Using 31 climate models, they showed that if emissions keep rising, the chance of a hiatus – a 10-year period with no significant warming – drops to virtually zero after 2030. The current hiatus will probably be followed by rapid warming as the heat trapped in the ocean escapes back into the atmosphere, so we are unlikely to get another decade of no warming before 2030. England believes it could be another century or more before the next hiatus.

But that could change if we slow greenhouse gas emissions now. If we can reach peak global emissions by 2040, the temperature rise will slow by the end of the century, and hiatus periods will become more likely.

Hiatuses can also be triggered by volcanic eruptions that spew particles into the air, reflecting sunlight away from Earth, as happened after the 1991 Mount Pinatubo eruption. But even if a volcano erupts it will make little difference. “After 2030, the rate of global warming is likely to be so fast that even large volcanic eruptions on the scale of Krakatoa are unlikely to drive a hiatus decade,” says team member Nicola Maher.

United Nations predicts climate hell in 2050 with imagined weather forecasts (The Guardian)

‘Reports from the future’ warn of floods, storms and searing heat in campaign for climate change summit

The United Nations is warning of floods, storms and searing heat fromArizona to Zambia within four decades, as part of a series of imagined weather forecasts released on Monday for a campaign publicising a UN climate summit.

“Miami South Beach is under water,” one forecaster says in a first edition of “weather reports from the future“, a series set in 2050 and produced by companies including Japan’s NHK, the US Weather Channel and ARD in Germany.

The UN World Meteorological Organization, which invited well-known television presenters to make videos to be issued before the summit on 23 September, said the scenarios were imaginary but realistic for a warming world.

A Zambian forecaster, for instance, describes a severe heatwave and an American presenter says: “The mega-drought in Arizona has claimed another casualty.”

Some, however, show extreme change. One Bulgarian presenter shows a red map with temperatures of 50C (122F) – far above the temperature record for the country of 45.2C (113F) recorded in 1916.

Climate change is affecting the weather everywhere. It makes it more extreme and disturbs established patterns. That means more disasters; more uncertainty,” the UN secretary general, Ban Ki-moon, said in a statement.

Ban has asked world leaders to make “bold pledges” to fight climate change at the meeting in New York. The summit is meant as a step towards a deal by almost 200 nations, due by the end of 2015, to slow global warming.

A UN report last year concluded it is at least 95% probable that human activities, rather than natural variations in the climate, are the main cause of global warming since 1950.

Scientists are exaggerating the climate change crisis.

There’s no need to reduce carbon dioxide emissions because the benefits of warmer temperatures outweigh the costs.

Over-the-top environmental regulations are linked to such problems as suicide and drug abuse.

These aren’t the ramblings of a right-wing conspiracy theorist, but the opinions expressed at a midsummer retreat for U.S. state legislators held by a powerful U.S. think tank and sponsored by corporations as varied as AT&T and TransCanada, the company behind the controversial Keystone XL pipeline proposal.

Internal documents from this summer’s Dallas meeting of the American Legislative Exchange Council, leaked to a watchdog group, reveal several sessions casting doubt on the scientific evidence of climate change. They also reveal sessions focused on crafting policies that reduce rules for fossil fuel companies and create obstacles for the development of alternative forms of energy.

The meeting, hosted in Dallas from July 30 to Aug. 1, involved a mix of lobbyists, U.S. legislators and climate change contrarians, and was sponsored by more than 50 large corporations, including several that do business in Alberta’s oilsands.

One workshop had the goal of teaching politicians “how to think and talk about climate and energy issues” and provided them with guidance for fighting environmental policies and regulations.

“Legislators are just there as foot soldiers, really,” said Chris Taylor, a Democratic state representative from Wisconsin and a member of ALEC.

Taylor, who said she belongs to the group in order to keep people informed about what it’s doing, said research groups appear to be writing policies presented at the meeting on behalf of corporations that are trying to get rid of obstacles to profit.

“Legislators aren’t coming up with these ideas,” she said.

An ALEC spokeswoman, Molly Fuhs, said in an email to the Star that all of its meetings are meant to bring together members “to discuss and debate model solutions to the issues facing the states,” using principles of limited government, free markets and federalism.

All of the model policies, which must first be introduced by a legislator member, are voted on and approved by a national board made up of 23 state legislators, she added.

“This is to ensure ALEC model policies are driven by, and are reflective of, state legislators’ ideas and the issues facing the states,” she wrote.

The group, founded in 1973, says it has about 2,000 elected Democratic and Republican state legislators in its membership. Its non-partisan status as an educational organization allows it to give U.S. tax receipts to its donors.

With nine separate committees made up of corporate representatives and politicians, the council says it can contribute to as many as 1,000 different policies or laws in a single year. And on average, about 20 per cent of these become laws or policies in areas such as international trade, the environment or health care, it says.

“For more than forty years, ALEC has helped lobbyists from some of the biggest polluters on the planet meet privately with U.S. lawmakers to discuss and model legislation,” said Nick Surgey, research director at U.S. watchdog Center for Media and Democracy.

“ALEC is a big reason the U.S. is so far behind in taking significant action to tackle climate change.”

A separate session on climate change at the ALEC retreat, presented by another educational charity, featured several proposals to discourage development of renewable energy, to stop new American rules to reduce pollution from coal power plants, as well as a “model resolution” in support of Keystone XL, which is seeking approval from the Obama administration.

According to a conference agenda, obtained by the Center for Media and Democracy, this presentation was given by Joseph Bast, president of the Heartland Institute, a Chicago-based conservative think tank. Neither Bast, an author and publisher with an undergraduate degree in economics, nor the institute responded to requests for comment.

Slides from the presentation show that it also challenged established scientific evidence on climate change, while proposing to dismantle the U.S. Environmental Protection Agency.

Other internal ALEC records released by the watchdog show that it previously asked its elected members to publicly speak out in support of Keystone XL, providing them with “information” to include in submissions for the U.S. State Department, which is reviewing the TransCanada project.

“They lobby,” Taylor, the Wisconsin Democrat, said of ALEC. “They come up with model policies. They send emails to legislators. They urge people to support model policies. They send thank-yous when the model policies pass. My goal in going is to make sure it’s not stealth, to make sure people know where these policies come from. And these policies come from big corporations through ALEC.”

The Harper government has also participated in an ALEC event, sending a Canadian diplomat, Canada’s consul general in Dallas, Paula Caldwell St-Onge, to a 2011 conference in New Orleans to promote the Keystone XL pipeline, the oilsands and other fossil fuels. Speaking notes from her presentation don’t mention climate change.

Fuhs, ALEC’s spokeswoman, confirmed that several multinational corporations were among those to sponsor the Dallas conference, including telecommunications giant AT&T, pharmaceutical companies Pfizer and Bayer and energy companies such as Chevron, Devon, Exxon Mobil and TransCanada.

But she stopped responding to questions from the Star after being asked about the internal documents circulated at the meeting and obtained by the watchdog group.

Most of the companies contacted by the Star confirmed they had sponsored the event, explaining that this didn’t necessarily mean they endorsed all of ALEC’s proposed policies.

Alberta-based TransCanada, which sponsored an “Ice Cream Social” event at the ALEC meetings in each of the past two years, downplayed its role.

“I cannot honestly speak to whether or not someone who was a consultant for our company was at the event — because we are not their only client — but no one was directed to be at this event to present views on behalf of TransCanada,” said TransCanada spokesman Shawn Howard. “I can’t be any clearer than that.”

Howard, who said the company’s contributions to ALEC weren’t considered to be charitable donations, said the sponsorship doesn’t mean TransCanada agrees with the organization’s policies.

“Reasonable people wouldn’t expect us to only go to or support things that are a perfect match for our own company’s views and values,” Howard said, noting TransCanada has a climate change policy that includes billions of dollars of investments in renewable energy.

“Sometimes you have to speak to people with different viewpoints to develop better public policy and decisions — that’s just common sense,” Howard said.

A spokesman for ExxonMobil told the Star the company didn’t want to comment about its sponsorship of ALEC, saying that it wasn’t a member of the organization. ALEC’s website lists representatives from 17 organizations on its “private enterprise advisory council” including ExxonMobil, AT&T, Pfizer, as well as Peabody Energy, the largest private-sector coal company in the world.

ALEC declined to explain the role of this “advisory council.”

A spokesman from Devon Energy, Tim Hartley, confirmed that it was “one of the many sponsors” of the Dallas meeting, explaining that the company “generally favours the principles of free markets and limited government that animate ALEC.” But he said he couldn’t discuss specific public policy issues.

“We interact with a variety of stakeholder groups in the course of our business, and we embrace our responsibility to participate in the free and open marketplace of ideas,” said Hartley.

Although she is often critical of ALEC, Taylor, who joined the organization as a legislative member a few years ago, said she doesn’t expect to be kicked out since it is trying to promote its bipartisan nature to preserve its charitable status.

She said energy was a major theme at the Dallas conference, driven by some large corporations, with one corporate representative from Peabody Energy urging the conference to help spark a “political tsunami” against new U.S. EPA regulations proposed to slash pollution from coal power plants.

Peabody Energy didn’t respond to a request for comment.

Surgey, from the Center for Media and Democracy, said one of his biggest concerns about ALEC is its secrecy.

“We have many of our state elected officials going on to these conferences, and yet we’re not allowed to know who they meet with,” said Surgey. “We just know that it’s a very large number of lobbyists from big multinational corporations but ALEC refuses to tell us who’s there.”

ALEC has also sponsored a pair of trips for U.S. politicians to the Alberta oilsands — described as an “oilsands academy” — arranging meetings for the politicians with representatives from TransCanada and Devon Energy, as well as one environmental group, the Pembina Institute, in October 2012.

TransCanada said it doesn’t organize or fund these types of visits, but it assists by freeing up staff to explain operations at facilities.

Sandi Walker, an Alberta government spokeswoman from the provincial department of international and intergovernmental relations, said it hosted 54 trips to the oilsands in 2012, including the fall visit co-ordinated by ALEC as part of ongoing efforts to inform legislators and officials about the industry with “fact-based information” to allow key decision-makers to make informed decisions about energy. Each trip typically cost about $3,000, she said.

She said an ALEC representative had contacted Alberta to set up the meeting, explaining that the province maintains relations with a variety of stakeholders and organizations in the U.S.

Walker said the province is committed to being a leader in greenhouse gas reduction technology by renewing its climate change strategy so that it can effectively reduce emissions at the source, noting it has already implemented a price on carbon emissions for industry.

While TransCanada’s pipeline proposal has popped up on the agenda at multiple ALEC events in recent years, Taylor said that the company’s latest “ice cream social” reminded her of what happened last year when it hosted a similar event.

The ice cream started melting, and in a crowd of skeptics, she joked that she thought this might be accepted as evidence of global warming.

Organização Mundial de Meteorologia lança série de vídeos sobre mudança climática (Fapesp)

Objetivo é sensibilizar sobre os impactos locais do aquecimento global; primeiro episódio prevê o tempo no Brasil no ano de 2050

05/09/2014

Agência FAPESP – A Organização Mundial de Meteorologia (OMM) lançou os primeiros episódios de uma série de vídeos com previsões do tempo projetadas para o ano de 2050. A primeira edição traz a previsão para o dia 8 de junho daquele ano no Brasil, apresentada por Claudia Celli, da RPC-TV, afiliada da TV Globo no Paraná.

O objetivo da iniciativa é sensibilizar as pessoas sobre os impactos locais das mudanças climáticas globais. Os vídeos trazem sempre apresentadores de televisão conhecidos em um determinado país – e os cenários são compatíveis com os projetados no quinto relatório do Painel Intergovernamental de Mudanças Climáticas (IPCC).

No caso do Brasil, a previsão é de muita chuva no sul do país e no oeste da Amazônia. A expectativa é que os níveis de chuva para o mês sejam superados em apenas alguns dias, aumentando o risco de inundações e deslizamentos. Para o Nordeste e o leste da Amazônia, a previsão é de seca.

O lançamento dos vídeos pela OMM ocorre em apoio ao pedido do secretário-geral da Organização das Nações Unidas (ONU), Ban Ki-moon, para que governos, empresários e líderes da sociedade civil concordem em agir para lidar com a mudança climática durante a cúpula climática da ONU, marcada para 23 de setembro, a fim de evitar que se concretizem as previsões dos piores cenários.

“A mudança climática está afetando o tempo em todo lugar. Isso torna o clima mais extremo e modifica os padrões estabelecidos. Isso significa mais desastres; mais incerteza”, diz Ban Ki-moon em uma mensagem no vídeo.

A edição sobre o Brasil traz ainda uma entrevista de Celli com José Marengo, pesquisador do Instituto Nacional de Pesquisas Espaciais (Inpe) e membro do Programa FAPESP de Pesquisa sobre Mudanças Climáticas Globais (PFPMCG).

“Nas regiões tropicais, em basicamente todo o Brasil, os aumentos de temperatura no fim do século poderão ultrapassar os 4º C. Em termos de chuva, o padrão muda um pouco. As previsões mostram reduções de chuva no leste da Amazônia e na região Nordeste e aumento de chuva no oeste da Amazônia e no extremo sul do Brasil”, afirma Marengo no vídeo.

“A resposta tem que ser imediata [às mudanças climáticas globais]. Nas próximas décadas tem que se chegar a um acordo internacional, tipo o Protocolo de Kyoto, para reduzir as emissões de gases de efeito estufa, porque reduzir essas emissões é a única forma de poder reduzir o aquecimento e reduzir os impactos à população”, acrescenta o pesquisador.

O vídeo com a previsão para o Japão também já está no ar. Nesta sexta-feira (05/09), será divulgado o boletim meteorológico para a Dinamarca.

Os outros países que terão vídeos sobre a previsão do tempo em 2050 são: Zâmbia, Burkina Faso, Estados Unidos, Bulgária, Filipinas, Bélgica, África do Sul, Islândia, Alemanha e Tanzânia.

How the IPCC is sharpening its language on climate change (The Carbon Brief)

01 Sep 2014, 17:40

Barometer | Shutterstock

The Intergovernmental Panel on Climate Change (IPCC) is sharpening the language of its latest draft synthesis report, seen by Carbon Brief.

Not only is the wording around how the climate is changing more decisive, the evidence the report references is stronger too, when compared to the  previous version published in 2007.

The synthesis report, due to be published on 2 November, will wrap up the IPCC’s fifth assessment (AR5) of climate change. It will summarise and draw together the information in IPCC reports on the science of climate change, its  impacts and the  ways it can be addressed.

We’ve compared a draft of the synthesis report with that published in 2007 to find out how they compare. Here are the key areas of change.

Irreversible impacts are being felt already

The AR5 draft synthesis begins with a decisive statement that human influence on the climate is “clear”, that recent emissions are the highest in history and that “widespread and consequential impacts” are already being felt.

This opening line shows how much has changed in the way the authors present their findings. In contrast, the 2007 report opened with a discussion of scientific progress and an extended paragraph on definitions.

There are also a couple of clear thematic changes in the 2014 draft. The first, repeated frequently throughout, is the idea that climate change impacts are already being felt.

For instance it says that the height of coastal floods has already increased and that climate-change-related risks from weather extremes such as heatwaves and heavy rain are “already moderate”.

These observations are crystallised in a long section on Article 2 of the UN’s climate change convention, which has been signed by every country of the world. Article 2 says that the objective of the convention is to avoid dangerous climate change.

The AR5 draft implies the world may already have failed in this task:

“Depending on value judgements and specific circumstances, currently observed impacts might already be considered dangerous for some communities.”

The second theme is a stronger emphasis on irreversible impacts compared to the 2007 version. The 2014 draft says:

“Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.”

It says that a large fraction of warming will be irreversible for hundreds to thousands of years and that the Greenland ice sheet will be lost when warming reaches between one and four degrees above pre-industrial temperatures. Current warming since pre-industrial times is about 0.8 degrees celsius.

In effect the report has switched tense from future conditional (“could experience”) to present continuous (“are experiencing”).  For instance it says there are signs that some corals and Arctic ecosystems “are already experiencing irreversible regime shifts” because of warming.

Stronger evidence than before

As well as these thematic changes in the use of language, the AR5 synthesis comes to stronger conclusions in many other areas.

This is largely because the scientific evidence has solidified in the intervening seven years, the IPCC says.

We’ve drawn together a collection of side-by-side statements so you can see for yourself how the conclusions have changed. Some of the shifts in language are subtle – but they are significant all the same.

Climate alarmism or climate realism?

The authors of the latest synthesis report seem to have made an effort to boost the impact of their words. They’ve used clearer and more direct language along with what appears to be a stronger emphasis on the negative consequences of inaction.

The language around relying on adaptation to climate change has also shifted. It now more clearly emphasises the need for mitigation to cut emissions, if the worst impacts of warming are to be avoided.

Some are bound to read this as an unwelcome excursion into advocacy. But others will insist it is simply a case of better presenting the evidence that was already there, along with advances in scientific knowledge.

Government representatives have the chance to go over the draft AR5 synthesis report with a fine toothcomb when they meet during 27-31 October.

Will certain countries try to tone down the wording, as they have been accused of doing in the past? Or will the new, more incisive language make the final cut?

To find out, tune in on 2 November when the final synthesis report will be published.

Water ‘thermostat’ could help engineer drought-resistant crops (Science Daily)

Summary: A gene that could help engineer drought-resistant crops has been identified by researchers. The gene, called OSCA1, encodes a protein in the cell membrane of plants that senses changes in water availability and adjusts the plant’s water conservation machinery accordingly. The findings could make it easier to feed the world’s growing population in the face of climate change. 


Duke University researchers have identified a gene that could help scientists engineer drought-resistant crops. The gene, called OSCA1, encodes a protein in the cell membrane of plants that senses changes in water availability and adjusts the plant’s water conservation machinery accordingly.

“It’s similar to a thermostat,” said Zhen-Ming Pei, an associate professor of biology at Duke.

The findings, which appear Aug. 28 in the journalNature, could make it easier to feed the world’s growing population in the face of climate change.

Drought is the major cause of crop losses worldwide. A dry spell at a crucial stage of the growing season can cut some crop yields in half.

Water shortages are expected to become more frequent and severe if climate change makes rainfall patterns increasingly unreliable and farmland in some regions continues to dry up. Coupled with a world population that is expected to increase by two billion to three billion by 2050, researchers worldwide are looking for ways to produce more food with less water.

Some researchers hope that genetic engineering — in addition to improved farming practices and traditional plant breeding — will add to the arsenal of techniques to help crops withstand summer’s swelter. But engineering plants to withstand drought has proven difficult to do, largely because plants use so many strategies to deal with dehydration and hundreds of genes are involved.

The problem is confounded by the fact that drought is often accompanied by heat waves and other stresses that require different coping strategies on the part of the plant, Pei said.

One way that plants respond to water loss is by boosting the levels of calcium within their cells. The calcium surge acts as an alarm signal that triggers coping mechanisms to help the plant rebalance its water budget. But until now, the molecular machinery that plants use to send this signal — and monitor water availability in general — remained unknown.

Pei and Duke colleagues Fang Yuan, James Siedow and others identified a gene that encodes a protein in the cell membranes of plant leaves and roots, called OSCA1, which acts as a channel that allows calcium to surge into the cell in times of drought.

The gene was identified in Arabidopsis thaliana, a small unassuming plant related to cabbage and canola that is the lab rat of plant research.

Plants with defective versions of the calcium channel don’t send an alarm signal under water stress like normal plants do.

When the researchers grew normal plants and plants with defective versions of the gene side by side in the same pot and exposed them to drought stress, the mutant plants experienced more wilting.

The findings could lead to new ways to help plants thrive when water is scarce.

The team’s next step is to manipulate the activity of the OSCA1 gene and related genes and see how those plants respond to drought — information that could lead to crops that respond more quickly and efficiently to dehydration.

“Plants that enter drought-fighting mode quickly and then switch back to normal growth mode quickly when drought stress is gone should be able to allocate energy more efficiently toward growth,” Pei said.
