Subcommittee Reviews Legislation to Improve Weather Forecasting (Subcommittee on Environmen, House of Representatives, USA)

MAY 23, 2013

Washington, D.C. – The Subcommittee on Environment today held a hearing to examine ways to improve weather forecasting at the National Oceanic and Atmospheric Administration (NOAA).  Witnesses provided testimony on draft legislation that would prioritize weather-related research at NOAA, in accordance with its critical mission to protect lives and property through enhanced weather forecasting. The hearing was timely given the recent severe tornadoes in the mid-west and super-storms like Hurricane Sandy.

Environment Subcommittee Chairman Chris Stewart (R-Utah): “We need a world-class system of weather prediction in the United States – one, as the National Academy of Sciences recently put it, that is ‘second to none.’ We can thank the hard-working men and women at  NOAA and their partners throughout the weather enterprise for the great strides that have been made in forecasting in recent decades.  But we can do better. And it’s not enough to blame failures on programming or sequestration or lack of other resources. As the events in Moore, Oklahoma have demonstrated, we have to do better. But the good news is that we can.”

Experts within the weather community have raised concern that the U.S. models for weather prediction have fallen behind Europe and other parts of the world in predicting weather events.The Weather Forecasting Improvement Act, draft legislation discussed at today’s hearing, would build upon the down payment made by Congress following Hurricane Sandy and restore the U.S. as a leader in this field through expanded computing capacity and data assimilation techniques.

Rep. Stewart: “The people of Moore, Oklahoma received a tornado warning 16 minutes before the twister struck their town. Tornado forecasting is difficult but lead times for storms have become gradually better. The draft legislation would prioritize investments in technology being developed at NOAA’s National Severe Storms Laboratory in Oklahoma, which ‘has the potential to provide revolutionary improvements in… tornado… warning lead times and accuracy, reducing false alarms’ and could move us toward the goal of being able to ‘warn on forecast.’”

The following witnesses testified today:

Overheated rhetoric on climate change doesn’t make for good policies (Washington Post)

By Lamar Smith, Published: May 19, 2013

Lamar Smith, a Republican, represents Texas’s 21st District in the U.S. House and is chairman of the House Committee on Science, Space and Technology.

Climate change is an issue that needs to be discussed thoughtfully and objectively. Unfortunately, claims that distort the facts hinder the legitimate evaluation of policy options. The rhetoric has driven some policymakers toward costly regulations and policies that will harm hardworking American families and do little to decrease global carbon emissions. The Obama administration’s decision to delay, and possibly deny, the Keystone XL pipeline is a prime example.

The State Department has found that the pipeline will have minimal impact on the surrounding environment and no significant effect on the climate. Recent expert testimony before the House Committee on Science, Space and Technology confirms this finding. In fact, even if the pipeline is approved and is used at maximum capacity, the resulting increase in carbon dioxide emissions would be a mere 12 one-thousandths of 1 percent (0.012 percent). There is scant scientific or environmental justification for refusing to approve the pipeline, a project that the State Department has also found would generate more than 40,000 U.S. jobs.

Contrary to the claims of those who want to strictly regulate carbon dioxide emissions and increase the cost of energy for all Americans, there is a great amount of uncertainty associated with climate science. These uncertainties undermine our ability to accurately determine how carbon dioxide has affected the climate in the past. They also limit our understanding of how anthropogenic emissions will affect future warming trends. Further confusing the policy debate, the models that scientists have come to rely on to make climate predictions have greatly overestimated warming. Contrary to model predictions, data released in October from the University of East Anglia’s Climate Research Unit show that global temperatures have held steady over the past 15 years, despite rising greenhouse gas emissions.

Among the facts that are clear, however, are that U.S. emissions contribute very little to global concentrations of greenhouse gas, and that even substantial cuts in these emissions are likely to have no effect on temperature. Data from the Energy Information Administration show, for example, that the United States cut carbon dioxide emissions by 12 percent between 2005 and 2012 while global emissions increased by 15 percent over the same period.

Using data from the Intergovernmental Panel on Climate Change (IPCC), a Science and Public Policy Institute paper published last month found that if the United States eliminated all carbon dioxide emissions, the overall impact on global temperature rise would be only 0.08 degrees Celsius by 2050.

Further confounding the debate are unscientific and often hyperbolic claims about the potential effects of a warmer world. In his most recent State of the Union address, President Obama said that extreme weather events have become “more frequent and intense,” and he linked Superstorm Sandy to climate change.

But experts at the National Oceanic and Atmospheric Administration have told the New York Times that climate change had nothing to do with Superstorm Sandy. This is underscored by last year’s IPCC report stating that there is “high agreement” among leading experts that trends in weather disasters, floods, tornados and storms cannot be attributed to climate change. While these claims may make for good political theater, their effect on recent public policy choices hurts the economy.

Last spring the Environmental Protection Agency proposed emissions standards that virtually prohibit new coal-fired power plants. As we await implementation of these strict new rules, additional regulations that will affect existing power plants, refineries and other manufactures are sure to follow. Analyses of these measures by the American Council for Capital Formation, which studies economic and environmental policy, show that they will raise both electricity rates and gas prices — costing jobs and hurting the economy — even as the EPA admits that these choices will have an insignificant impact on global climate change (a point former EPA administrator Lisa Jackson confessed during a Senate hearing in 2009).

Instead of pursuing heavy-handed regulations that imperil U.S. jobs and send jobs (and their emissions) overseas, we should take a step back from the unfounded claims of impending catastrophe and think critically about the challenge before us. Designing an appropriate public policy response to this challenge will require that we fully assess the facts and the uncertainties surrounding this issue, and that we set aside the hyped rhetoric.

Climate research nearly unanimous on human causes, survey finds (The Guardian)

Of more than 4,000 academic papers published over 20 years, 97.1% agreed that climate change is anthropogenic

A survey of thousands of peer-reviewed papers in scientific journals has found 97.1% agreed that climate change is caused by human activity.

Authors of the survey, published on Thursday in the journal Environmental Research Letters, said the finding of near unanimity provided a powerful rebuttal to climate contrarians who insist the science of climate change remains unsettled.

The survey considered the work of some 29,000 scientists published in 11,994 academic papers. Of the 4,000-plus papers that took a position on the causes of climate change only 0.7% or 83 of those thousands of academic articles, disputed the scientific consensus that climate change is the result of human activity, with the view of the remaining 2.2% unclear.

The study described the dissent as a “vanishingly small proportion” of published research.

“Our findings prove that there is a strong scientific agreement about the cause of climate change, despite public perceptions to the contrary,” said John Cook of the University of Queensland, who led the survey.

Public opinion continues to lag behind the science. Though a majority of Americans accept the climate is changing, just 42% believed human activity was the main driver, in a poll conducted by the Pew Research Centre last October.

“There is a gaping chasm between the actual consensus and the public perception,” Cook said in a statement.

The study blamed strenuous lobbying efforts by industry to undermine the science behind climate change for the gap in perception. The resulting confusion has blocked efforts to act on climate change.

The survey was the most ambitious effort to date to demonstrate the broad agreement on the causes of climate change, covering 20 years of academic publications from 1991-2011.

In 2004, Naomi Oreskes, an historian at the University of California, San Diego,surveyed published literature, releasing her results in the journal Science. She too came up with a similar finding that 97% of climate scientists agreed on the causes of climate change.

She wrote of the new survey in an email: “It is a nice, independent confirmation, using a somewhat different methodology than I used, that comes to the same result. It also refutes the claim, sometimes made by contrarians, that the consensus has broken down, much less ‘shattered’.”

The Cook survey was broader in its scope, deploying volunteers from theSkepticalScience.com website to review scientific abstracts. The volunteers also asked authors to rate their own views on the causes of climate change, in another departure from Oreskes’s methods.

The authors said the findings could help close the gap between scientific opinion and the public on the causes of climate change, or anthropogenic global warming, and so create favourable conditions for political action on climate.

“The public perception of a scientific consensus on AGW [anthropogenic, ie man-made, global warming] is a necessary element in public support for climate policy,” the study said.

However, Prof Robert Brulle, a sociologist at Drexel University who studies the forces underlying attitudes towards climate change, disputed the idea that educating the public about the broad scientific agreement on the causes of climate change would have an effect on public opinion – or on the political conditions for climate action.

He said he was doubtful that convincing the public of a scientific consensus on climate change would help advance the prospects for political action. Having elite leaders call for climate action would be far more powerful, he said.

“I don’t think people really want to come around to grips with the fact that climate change is a highly ideological issue and it is not amenable to the information deficit model,” he said.

“The information deficit model, this idea that if you just pile on more information people will get convinced, is just completely inadequate, he said. “It strengthens the people who actually read and pay attention but it is certainly not going to change or shift the opinions of others.”

Jon Krosnick, professor in humanities and social sciences at Stanford university and an expert on public opinion on climate change, said: “I assume that sceptics would say that there is bias in the editorial process so that the papers ultimately published are not an accurate reflection of the opinions of scientists.”

“It’s happening now… The village is sinking” (The Guardian)

Residents of Newtok, Alaska, know they must evacuate, but who will pay the $130m cost of moving them?

One afternoon in the waning days of winter, the most powerful man in Newtok, Alaska, hopped on a plane and flew 1,000 miles to plead for the survival of his village. Stanley Tom, Newtok’s administrator, had a clear purpose for his trip: find the money to move the village on the shores of the Bering Sea out of the way of an approaching disaster caused by climate change.

Newtok was rapidly losing ground to erosion. The land beneath the village was falling into the river. Tom needed money for bulldozers to begin preparing a new site for the village on higher ground. He needed funds for an airstrip, He came back from his meetings in Juneau, the Alaskan state capital, with expressions of sympathy – but nothing in the way of the cash he desperately needed. “It’s really complicated,” he said. “There are a lot of obstacles.”

Those obstacles – financial, legal and a supremely frustrating bureaucratic process – had slowed down the move for so long that some in Newtok, which is about 400 miles south of the Bering Strait that separates the US from Russia, feared they would be stuck as the village went down around them, houses swallowed up by the river.

“It’s really alarming,” said Tom, slumped in an armchair a few hours after his return to the village. “I have a hard time sleeping, and I’m getting up early in the morning. I am worried about it every day.”

The uncertainty was tearing the village apart. It also began to turn the village against Tom.

Over the winter, a large group of villagers decided that their administrator was not up to the job. By the time he returned from this particular trip, the dissidents had voted to replace the village council and to sack Tom – a vote that he ignored.

“The way I see it, we need someone who knows how to do the work,” said Katherine Charles, one of Tom’s most vocal critics. “I feel like we are being neglected. We are still standing here and we don’t know when we are going to move. For years now we have been frustrated. I have to ask myself: why are we even still here?”

It’s been more than a decade since Tom took charge of running Newtok, and leading the village out of climate disaster to higher ground.

The ground beneath Newtok is disappearing. Natural erosion has accelerated due to climate change, with large areas of land lost to the Ninglick river each year. A study by the Army Corps of Engineers found the highest point in the village would be below water level by 2017. The proximity of the threat to Newtok means that its villages are likely to be America’s first climate refugees.

Officials in Anchorage say Tom has worked tirelessly to move the village out of the way of a rampaging river. Among the relatively small circle of bureaucrats and lawyers who concern themselves with the problems of small and remote indigenous Alaskan villages, the Newtok administrator has a stellar reputation. He has won leadership awards from Native American groups in the rest of the country.

Tom said he hoped to make a big push this summer, acquiring heavy equipment that locals could use to begin moving some of the existing houses over to the new village site at Mertarvik nine miles to the south.

“It’s really happening right now. The village is sinking and flooding and eroding,” he said. He said he was planning to move his own belongings to the new village site this summer – and that villagers should start doing the same.

But Tom, despite his lobbying missions to Juneau and strong reputation with government officials, has failed to inject federal and state officials with that same sense of urgency.

Melting permafrost, sea-level rise, erosion – these are some of the worst consequences of climate change for Alaska. But none of those elements in Newtok’s slow destruction are recognised as disasters under existing legislation.

That means there is no designated pot of money set aside for those affected communities – unlike cities or towns destroyed by floods or tornados.

We weren’t thinking of climate change when federal disaster relief legislation was passed.

“We weren’t thinking of climate change when federal disaster relief legislation was passed,” said Robin Bronen, a human rights lawyer in Anchorage who has made a dozen visits to Newtok. “Our legal system is not set up. The institutions that we have created to respond to disasters are not up to the task of responding to climate change.”

In Bronen’s view, Congress needed to rewrite existing disaster legislation to take account of climate change. Communities needed to be able to access those disaster funds — if not to rebuild in place, which is not feasible in Newtok’s case, then to move.

The authorities also had responsibility under the treaty agreements with indigenous Alaskan tribes to guarantee the safety and wellbeing of indigenous communities, she argued.

“This is completely a human rights issue,” Bronen said. “When you are talking about a people who have done the least to contribute to our climate crisis facing such dramatic consequences as a result of climate change, we have a moral and legal responsibility to respond and provide the funding needed so that these communities are not in danger.”

Until then, however, it was up to Tom to find new ways to prise funds out of an unresponsive bureaucracy. It turned out that he had a knack for it.

Government officials praised Tom for finding other sources of funds, such as development grants, and putting them to use for building the new village site. But it has been a laborious process for the remote village to find its way through the different funding agencies and a maze of competing regulations.

As Tom found out, each agency had its own set of rules. The state government would not build a school for fewer than 10 children. The federal government would not build an airstrip at a village without a post office. But the rules, from Newtok’s vantage point, appeared to have at least one point in common. They seemed to conspire against the village ever getting its move off the ground.

In 2011, Alaska’s government published a timetable for Newtok’s move, setting out dates for building an emergency centre, housing, an airstrip – all items on Tom’s list. Two years later, the plan is already behind schedule and the official who oversaw that original timetable said there was little chance of getting back on track.

Newtok is something that is probably going to play out over several decades unless it reaches a dire point where something has to be done immediately to keep the people safe

“Newtok is something that is probably going to play out over several decades unless it reaches a dire point where something has to be done immediately to keep the people safe,” said Larry Hartig, who heads Alaska’s Department of Environmental Conservation.

Officially, the government of Alaska remains committed to helping Newtok and all the other indigenous Alaskan villages that are threatened by climate change.

Almost all of Alaska’s indigenous villages – more than 180 – are experiencing the effects of climate change, including severe flooding and erosion. Some may be able to hold back rivers and sea, but others will have to move. About half a dozen villages, including Newtok, face extreme risks.

“I am not going to tell any community that they are not going to survive. If the residents want to survive, we will help them,” said Mead Treadwell, the state’s lieutenant governor.

But the cost of relocating just one village — Newtok — could run as high as $130m, according to an estimate by the Army Corps of Engineers. That’s more than $350,000 per villager. Multiply that by half a dozen, or several more times, and the cost of protecting indigenous Alaskan villages from climate change soon soars into the billions.

So far, Newtok has received a total of about $12m in state funds over the past four years, according to George Owletuck, a consultant hired by Tom to help with the move. Much of that has already gone, to build a barge landing, a few new homes, and an emergency evacuation centre – in case the village does not manage to move in time.

Officially, federal and state government agencies have spent some $27m getting Mertarvik ready, although a considerable share of that figure, some $6m, did not go directly to the relocation, said Sally Russell Cox, the state official overseeing the move. And there is still no major infrastructure completed at Mertarvik.

Would the government of Alaska commit to picking up the rest of the tab for Newtok and the other villages?

Alaska’s oil revenues have fallen off over the years. In 2012, the state slipped into second place for oil production behind North Dakota. Treadwell admitted the state government would not cover the entire cost of fortifying or moving all of the villages threatened by climate change.

“On the question of is there money to help them with one cheque? That is something there clearly is not,” he said.

Treadwell suggested some of the at-risk villages could raise funds by setting themselves up as hubs for oil companies hoping to drill in Arctic waters.

However, a number of oil companies have put their Arctic drilling plans on hold for 2013 and 2014. Treadwell admitted there was as yet no comprehensive climate change plan for Newtok and other villages. “I think it’s going to be piece by piece with each community and many different pots of money,” he said.

In the case of Newtok, Owletuck, the consultant, had big ideas for financing the move: growing fruit and vegetables hydroponically in green houses, or testing the possibilities of producing biofuels from algae.

He let it be known the village may even have found a mysterious benefactor. Owletuck said he’d had an approach from private individuals, whom he declined to name, wanting to donate $22m to the move.

None of those propositions have materialised, however. And after more than a decade of uncertainty about the future under climate change, the basic infrastructure of Newtok is coming apart.

The impact on Newtok

Snow covers up a lot of Newtok’s flaws: the open sewage pits, the broken board walk over mudflats, some of the abandoned snowmobile wrecks.

Newtok has for years been considered a “distressed village”, with average income of $16,000, well below the rest of the state. Fewer than half of adults in the village have paid work. But even within those dismal measures, conditions have sharply deteriorated in the years since the village has been planning to move.

Aside from the clinic and the school, most buildings are in a state of advanced dilapidation. The floor in the community hall sags like an old mattress. The community laundry is out of order.

In the cramped offices of the traditional council, where Tom works, the furniture dates from the 1970s or 1980s, mid-brown vinyl chairs where the casing has split open, revealing the dirty foam inside. It’s not unheard of to find families of 10 or 12 children living in houses of less than 800 sq ft – and none of those homes have flush toilets or running water.

Early mornings find the men of the household trudging out of their homes with 5 gallon buckets of waste, which get dumped at various spots on the edges of the village, including a small stream.

The diesel-powered generator was nearing the end of its life span. The water treatment plant was shut down last October after people began getting sick. Tom said there was contamination from leaking jet fuel at the airport.

For now, villagers are drawing water from the school, which had a separate system. But the school principal said he would have to cut that off in May to preserve the system for the schoolchildren.

Tom said there was nothing he could do. Government agencies would not fund improvements at the current village site, because of the plan to move. “There is no money to improve our community,” he said. “We are suspended from federal and state agencies and there is no way of improving our lives over here. The agencies do not want to work on both villages at once.”

By last October, frustration with the stalled move and conditions in the village exploded. Villagers accused their own council of failing to hold regular elections, and raised a petition to throw out the leaders and replace Tom.

Some accused him of presiding over a dictatorship in the village. Others speculated that he and the paid consultant, Oweituck, were plotting to rob the relocation funds.

One of the dissidents, a relative newcomer to the village, posted ferocious criticism of Tom on Facebook calling for rebellion.

The dissidents organised elections, voted out the old council and installed their own leaders. Tom ignored the result. “Let them cry all they want,” he said. “I don’t care. They are not going to help my community. I am way ahead of these guys.”

The upheavals in Newtok are sadly familiar to those who have worked with indigenous Alaskan villages confronting climate change. “I don’t think you would find one community that says they are happy with the pace that’s gone on,” said Patricia Cochran, director of the Alaska Native Science Commission.

“To be honest with you, I think the state and the feds have done a terrible job, not only in assessing the conditions that communities are living within but in responding to them,” she said. “Because these communities are listed as threatened and may potentially be relocated, they are not able to get any funds now for infrastructure that is being damaged right now.”

That leaves communities stuck in a limbo that can carry for years or even decades.

That’s what has become of Newtok. The effects are devastating, said Charles. Beyond all her anger she admitted was an all-enveloping fear. “Sometimes I get scared. I’m scared for my own family. How will I take care of them if the relocation doesn’t start right away?”

She had been waiting for years to see the beginnings of any new settlement in rural Alaska rising up on the rocky hill of Mertarvik: the airport, the barge landing, the school, the houses. None of it was there yet, and Charles said she was coming close to despair.

“It’s been going on for I don’t know how long, and I am beginning to lose hope.”

For Insurers, No Doubts on Climate Change (N.Y.Times)

Master Sgt. Mark Olsen/U.S. Air Force, via Associated Press. Damage in Mantoloking, N.J., after Hurricane Sandy. Natural disasters caused $35 billion in private property losses last year.

By EDUARDO PORTER

Published: May 14, 2013

If there were one American industry that would be particularly worried about climate change it would have to be insurance, right?

From Hurricane Sandy’s devastating blow to the Northeast to the protracted drought that hit the Midwest Corn Belt, natural catastrophes across the United States pounded insurers last year, generating$35 billion in privately insured property losses, $11 billion more than the average over the last decade.

And the industry expects the situation will get worse. “Numerous studies assume a rise in summer drought periods in North America in the future and an increasing probability of severe cyclones relatively far north along the U.S. East Coast in the long term,” said Peter Höppe, who heads Geo Risks Research at the reinsurance giant Munich Re. “The rise in sea level caused by climate change will further increase the risk of storm surge.” Most insurers, including the reinsurance companies that bear much of the ultimate risk in the industry, have little time for the arguments heard in some right-wing circles that climate change isn’t happening, and are quite comfortable with the scientific consensus that burning fossil fuels is the main culprit of global warming.

“Insurance is heavily dependent on scientific thought,” Frank Nutter, president of the Reinsurance Association of America, told me last week. “It is not as amenable to politicized scientific thought.”

Yet when I asked Mr. Nutter what the American insurance industry was doing to combat global warming, his answer was surprising: nothing much. “The industry has really not been engaged in advocacy related to carbon taxes or proposals addressing carbon,” he said. While some big European reinsurers like Munich Re and Swiss Re support efforts to reduce CO2 emissions, “in the United States the household names really have not engaged at all.” Instead, the focus of insurers’ advocacy efforts is zoning rules and disaster mitigation.

Last week, scientists announced that the concentration of heat-trapping carbon dioxide in the atmosphere had reached 400 parts per million — its highest level in at least three million years, before humans appeared on the scene. Back then, mastodons roamed the earth, the polar ice caps were smaller and the sea level was as much as 60 to 80 feet higher.

The milestone puts the earth nearer a point of no return, many scientists think, when vast, disruptive climate change is baked into our future. Pietr P. Tans, who runs the monitoring program at the National Oceanic and Atmospheric Administration, told my colleague Justin Gillis: “It symbolizes that so far we have failed miserably in tackling this problem.” And it raises a perplexing question: why hasn’t corporate America done more to sway its allies in the Republican Party to try to avert a disaster that would clearly be devastating to its own interests?

Mr. Nutter argues that the insurance industry’s reluctance is born of hesitation to become embroiled in controversies over energy policy. But perhaps its executives simply don’t feel so vulnerable. Like farmers, who are largely protected from the ravages of climate change by government-financed crop insurance, insurers also have less to fear than it might at first appear.

The federal government covers flood insurance, among the riskiest kind in this time of crazy weather. And insurers can raise premiums or even drop coverage to adjust to higher risks. Indeed, despite Sandy and drought, property and casualty insurance in the United States was more profitable in 2012 than in 2011, according to the Property Casualty Insurers Association of America.

But the industry’s analysis of the risks it faces is evolving. One sign of that is how some top American insurers responded to a billboard taken out by the conservative Heartland Institute, a prominent climate change denier that has received support from the insurance industry.

The billboard had a picture of Theodore Kaczynski, the Unabomber, who asked: “I still believe in global warming. Do you?”

Concerned about global warming and angry to be equated with a murderous psychopath, insurance companies like Allied World, Renaissance Re, State Farm and XL Groupdropped their support for Heartland.

Even more telling, Eli Lehrer, a Heartland vice president who at the time led an insurance-financed project, left the group and helped start the R Street Institute, a standard conservative organization in all respects but one: it believes in climate change and supports a carbon tax to combat it. And it is financed largely with insurance industry money.

Mr. Lehrer points out that a carbon tax fits conservative orthodoxy. It is a broad and flat tax, whose revenue can be used to do away with the corporate income tax — a favorite target of the right. It provides a market-friendly signal, forcing polluters to bear the cost imposed on the rest of us and encouraging them to pollute less. And it is much preferable to a parade of new regulations from the Environmental Protection Agency.

“We are having a debate on the right about a carbon tax for the first time in a long time,” Mr. Lehrer said.

Bob Inglis, formerly a Republican congressman from South Carolina who lost his seat in the 2010 primary to a Tea Party-supported challenger, is another member of this budding coalition. Before he left Congress, he proposed a revenue-neutral bill to create a carbon tax and cut payroll taxes.

Changing the political economy of a carbon tax remains an uphill slog especially in a stagnant economy. But Mr. Inglis notices a thaw. “The best way to do this is in the context of a grand bargain on tax reform,” he said. “It could happen in 2015 or 2016, but probably not before.”

He lists a dozen Republicans in the House and eight in the Senate who would be open to legislation to help avert climate change. He notes that Exelon, the gas and electricity giant, is sympathetic to his efforts — perhaps not least because a carbon tax would give an edge to gas over its dirtier rival, coal. Exxon, too, has also said a carbon tax would be the most effective way to reduce emissions. So why hasn’t the insurance industry come on board?

Robert Muir-Wood is the chief research officer of Risk Management Solutions, one of two main companies the insurance industry relies on to crunch data and model future risks. He argues that insurers haven’t changed their tune because — with the exception of 2004 and 2005, when a string of hurricanes from Ivan to Katrina caused damage worth more than $200 billion — they haven’t yet experienced hefty, sustained losses attributable to climate change.

“Insurers were ready to sign up to all sorts of actions against climate change,” Mr. Muir-Wood told me from his office in London. Then the weather calmed down.

Still, Mr. Muir-Wood notes that the insurance industry faces a different sort of risk: political action. “That is the biggest threat,” he said. When insurers canceled policies and raised premiums in Florida in 2006, politicians jumped on them. “Insurers in Florida,” he said, “became Public Enemy No. 1.”

And that’s the best hope for those concerned about climate change: that global warming isn’t just devastating for society, but also bad for business.

Climate slowdown means extreme rates of warming ‘not as likely’ (BBC)

19 May 2013 Last updated at 17:31 GMT

By Matt McGrath – Environment correspondent, BBC News

The impacts of rising temperature are being felt particularly keenly in the polar regions

Scientists say the recent downturn in the rate of global warming will lead to lower temperature rises in the short-term.

Since 1998, there has been an unexplained “standstill” in the heating of the Earth’s atmosphere.

Writing in Nature Geoscience, the researchers say this will reduce predicted warming in the coming decades.

But long-term, the expected temperature rises will not alter significantly.

“The most extreme projections are looking less likely than before” – Dr Alexander Otto, University of Oxford

The slowdown in the expected rate of global warming has been studied for several years now. Earlier this year, the UK Met Office lowered their five-year temperature forecast.

But this new paper gives the clearest picture yet of how any slowdown is likely to affect temperatures in both the short-term and long-term.

An international team of researchers looked at how the last decade would impact long-term, equilibrium climate sensitivity and the shorter term climate response.

Transient nature

Climate sensitivity looks to see what would happen if we doubled concentrations of CO2 in the atmosphere and let the Earth’s oceans and ice sheets respond to it over several thousand years.

Transient climate response is much shorter term calculation again based on a doubling of CO2.

The Intergovernmental Panel on Climate Change reported in 2007 that the short-term temperature rise would most likely be 1-3C (1.8-5.4F).

But in this new analysis, by only including the temperatures from the last decade, the projected range would be 0.9-2.0C.

IceThe report suggests that warming in the near term will be less than forecast

“The hottest of the models in the medium-term, they are actually looking less likely or inconsistent with the data from the last decade alone,” said Dr Alexander Otto from the University of Oxford.

“The most extreme projections are looking less likely than before.”

The authors calculate that over the coming decades global average temperatures will warm about 20% more slowly than expected.

But when it comes to the longer term picture, the authors say their work is consistent with previous estimates. The IPCC said that climate sensitivity was in the range of 2.0-4.5C.

Ocean storage

This latest research, including the decade of stalled temperature rises, produces a range of 0.9-5.0C.

“It is a bigger range of uncertainty,” said Dr Otto.

“But it still includes the old range. We would all like climate sensitivity to be lower but it isn’t.”

The researchers say the difference between the lower short-term estimate and the more consistent long-term picture can be explained by the fact that the heat from the last decade has been absorbed into and is being stored by the world’s oceans.

Not everyone agrees with this perspective.

Prof Steven Sherwood, from the University of New South Wales, says the conclusion about the oceans needs to be taken with a grain of salt for now.

“There is other research out there pointing out that this storage may be part of a natural cycle that will eventually reverse, either due to El Nino or the so-called Atlantic Multidecadal Oscillation, and therefore may not imply what the authors are suggesting,” he said.

The authors say there are ongoing uncertainties surrounding the role of aerosols in the atmosphere and around the issue of clouds.

“We would expect a single decade to jump around a bit but the overall trend is independent of it, and people should be exactly as concerned as before about what climate change is doing,” said Dr Otto.

Is there any succour in these findings for climate sceptics who say the slowdown over the past 14 years means the global warming is not real?

“None. No comfort whatsoever,” he said.

Câmara de São Paulo aprova envio de torpedo para alertar chuvas (Folha de S.Paulo)

16/05/2013 – 17h01

GIBA BERGAMIM JR., DE SÃO PAULO

Atualizado às 17h54.

A Câmara de São Paulo aprovou um projeto que obriga a prefeitura a enviar mensagens de texto aos celulares dos paulistanos com alertas sobre a chegada de chuvas e de iminentes alagamentos.

De autoria do vereador Ricardo Young (PPS), o projeto agora precisa ser sancionado pelo prefeito Fernando Haddad (PT) para começar a valer.

Hoje, a única maneira de se informar sobre isso é acompanhando o noticiário nas rádios e emissoras de TV ou por meio do site do CGE (Centro de Gerenciamento de Emergências), da prefeitura, que monitora as chuvas na cidade.

O vereador diz que se inspirou em iniciativas do tipo nos Estados Unidos e Europa para dar informações sobre nevascas, por exemplo.

Em 2011, a prefeitura deu início a um projeto semelhante, mas apenas para os moradores da região da favela Pantanal, na zona leste de São Paulo, que sofreu com as enchentes durante quase dois meses inteiros durante o verão.

De acordo com o texto de Young, o município terá que celebrar convênios com empresas de telefonia móvel. As informações terão que ser passadas com antecedência de pelo menos duas horas aos paulistanos.

Segundo o parlamentar, o projeto permitiria que empresas, repartições públicas e escolas pudessem antecipar o fim do expediente para que os paulistanos cheguem em casa antes das chuvas.

PROJETOS

Também foi aprovado projeto dos vereadores Antonio Goulart (PSD) e Roberto Trípoli (PV) que permite que os animais de estimação sejam enterrados no mesmo jazigo de seus donos em cemitérios municipais. O projeto irá a segunda votação.

A um ano da Copa do Mundo, os vereadores também deram o título de cidadão paulistano para o presidente da Fifa, Joseph Blatter

Earth’s Current Warmth Not Seen in the Last 1,400 Years or More, Says Study (Science Daily)

Apr. 21, 2013 — Fueled by industrial greenhouse gas emissions, Earth’s climate warmed more between 1971 and 2000 than during any other three-decade interval in the last 1,400 years, according to new regional temperature reconstructions covering all seven continents. This period of humanmade global warming, which continues today, reversed a natural cooling trend that lasted several hundred years, according to results published in the journalNature Geoscience by more than 80 scientists from 24 nations analyzing climate data from tree rings, pollen, cave formations, ice cores, lake and ocean sediments, and historical records from around the world.

“This paper tells us what we already knew, except in a better, more comprehensive fashion,” said study co-author Edward Cook, a tree-ring scientist at Lamont-Doherty Earth Observatory who led the Asia reconstruction.

The study also found that Europe’s 2003 heat wave and drought, which killed an estimated 70,000 people, happened during Europe’s hottest summer of the last 2,000 years. “Summer temperatures were intense that year and accompanied by a lack of rain and very dry soil conditions over much of Europe,” said study co-author Jason Smerdon, a climate scientist at Lamont-Doherty and one of the lead contributors to the Europe reconstruction. Though summer 2003 set a record for Europe, global warming was only one of the factors that contributed to the temperature conditions that summer, he said.

The study is the latest to show that the Medieval Warm Period, from about 950 to 1250, may not have been global, and may not have happened at the same time in places that did grow warmer. While parts of Europe and North America were fairly warm between 950 and 1250, South America stayed relatively cold, the study says. Some people have argued that the natural warming that occurred during the medieval ages is happening today, and that humans are not responsible for modern day global warming. Scientists are nearly unanimous in their disagreement “If we went into another Medieval Warm Period again that extra warmth would be added on top of warming from greenhouse gases,” said Cook.

Temperatures varied less between continents in the same hemisphere than between hemispheres. “Distinctive periods, such as the Medieval Warm Period or the Little Ice Age stand out, but do not show a globally uniform pattern,” said co-author Heinz Wanner, a scientist at the University of Bern. By 1500, temperatures dropped below the long-term average everywhere, though colder temperatures emerged several decades earlier in the Arctic, Europe and Asia.

The most consistent trend across all regions in the last 2,000 years was a long-term cooling, likely caused by a rise in volcanic activity, decrease in solar irradiance, changes in land-surface vegetation, and slow variations in Earth’s orbit. With the exception of Antarctica, cooling tapered off at the end of the 19th century, with the onset of industrialization. Cooler 30-year periods between 830 and 1910 were particularly pronounced during weak solar activity and strong tropical volcanic eruptions. Both phenomena often occurred simultaneously and led to a drop in the average temperature during five distinct 30- to 90-year intervals between 1251 and 1820. Warming in the 20th century was on average twice as large in the northern continents as it was in the Southern Hemisphere. During the past 2000 years, some regions experienced warmer 30-year intervals than during the late 20th century. For example, in Europe the years between 21 and 80 AD were likely warmer than the period 1971-2000.

Carbon bubble will plunge the world into another financial crisis – report (The Guardian)

Trillions of dollars at risk as stock markets inflate value of fossil fuels that may have to remain buried forever, experts warn

The world could be heading for a major economic crisis as stock marketsinflate an investment bubble in fossil fuels to the tune of trillions of dollars, according to leading economists.

“The financial crisis has shown what happens when risks accumulate unnoticed,” said Lord (Nicholas) Stern, a professor at the London School of Economics. He said the risk was “very big indeed” and that almost all investors and regulators were failing to address it.

The so-called “carbon bubble” is the result of an over-valuation of oil,coal and gas reserves held by fossil fuel companies. According to a report published on Friday, at least two-thirds of these reserves will have to remain underground if the world is to meet existing internationally agreed targets to avoid the threshold for “dangerous” climate changeIf the agreements hold, these reserves will be in effect unburnable and so worthless – leading to massive market losses. But the stock markets are betting on countries’ inaction on climate change.

The stark report is by Stern and the thinktank Carbon Tracker. Their warning is supported by organisations including HSBC, Citi, Standard and Poor’s and the International Energy Agency. The Bank of England has also recognised that a collapse in the value of oil, gas and coal assets as nations tackle global warming is a potential systemic risk to the economy, with London being particularly at risk owing to its huge listings of coal.

Stern said that far from reducing efforts to develop fossil fuels, the top 200 companies spent $674bn (£441bn) in 2012 to find and exploit even more new resources, a sum equivalent to 1% of global GDP, which could end up as “stranded” or valueless assets. Stern’s landmark 2006 reporton the economic impact of climate change – commissioned by the then chancellor, Gordon Brown – concluded that spending 1% of GDP would pay for a transition to a clean and sustainable economy.

The world’s governments have agreed to restrict the global temperature rise to 2C, beyond which the impacts become severe and unpredictable. But Stern said the investors clearly did not believe action to curb climate change was going to be taken. “They can’t believe that and also believe that the markets are sensibly valued now.”

“They only believe environmental regulation when they see it,” said James Leaton, from Carbon Tracker and a former PwC consultant. He said short-termism in financial markets was the other major reason for the carbon bubble. “Analysts say you should ride the train until just before it goes off the cliff. Each thinks they are smart enough to get off in time, but not everyone can get out of the door at the same time. That is why you get bubbles and crashes.”

Paul Spedding, an oil and gas analyst at HSBC, said: “The scale of ‘listed’ unburnable carbon revealed in this report is astonishing. This report makes it clear that ‘business as usual’ is not a viable option for the fossil fuel industry in the long term. [The market] is assuming it will get early warning, but my worry is that things often happen suddenly in the oil and gas sector.”

HSBC warned that 40-60% of the market capitalisation of oil and gas companies was at risk from the carbon bubble, with the top 200 fossil fuel companies alone having a current value of $4tn, along with $1.5tn debt.

Lord McFall, who chaired the Commons Treasury select committee for a decade, said: “Despite its devastating scale, the banking crisis was at its heart an avoidable crisis: the threat of significant carbon writedown has the unmistakable characteristics of the same endemic problems.”

The report calculates that the world’s currently indicated fossil fuel reserves equate to 2,860bn tonnes of carbon dioxide, but that just 31% could be burned for an 80% chance of keeping below a 2C temperature rise. For a 50% chance of 2C or less, just 38% could be burned.

Carbon capture and storage technology, which buries emissions underground, can play a role in the future, but even an optimistic scenario which sees 3,800 commercial projects worldwide would allow only an extra 4% of fossil fuel reserves to be burned. There are currently no commercial projects up and running. The normally conservativeInternational Energy Agency has also concluded that a major part of fossil fuel reserves is unburnable.

Citi bank warned investors in Australia’s vast coal industry that little could be done to avoid the future loss of value in the face of action on climate change. “If the unburnable carbon scenario does occur, it is difficult to see how the value of fossil fuel reserves can be maintained, so we see few options for risk mitigation.”

Ratings agencies have expressed concerns, with Standard and Poor’s concluding that the risk could lead to the downgrading of the credit ratings of oil companies within a few years.

Steven Oman, senior vice-president at Moody’s, said: “It behoves us as investors and as a society to know the true cost of something so that intelligent and constructive policy and investment decisions can be made. Too often the true costs are treated as unquantifiable or even ignored.”

Jens Peers, who manages €4bn (£3bn) for Mirova, part of €300bn asset managers Natixis, said: “It is shocking to see the report’s numbers, as they are worse than people realise. The risk is massive, but a lot of asset managers think they have a lot of time. I think they are wrong.” He said a key moment will come in 2015, the date when the world’s governments have pledged to strike a global deal to limit carbon emissions. But he said that fund managers need to move now. If they wait till 2015, “it will be too late for them to take action.”

Pension funds are also concerned. “Every pension fund manager needs to ask themselves have we incorporated climate change and carbon risk into our investment strategy? If the answer is no, they need to start to now,” said Howard Pearce, head of pension fund management at the Environment Agency, which holds £2bn in assets.

Stern and Leaton both point to China as evidence that carbon cuts are likely to be delivered. China’s leaders have said its coal use will peak in the next five years, said Leaton, but this has not been priced in. “I don’t know why the market does not believe China,” he said. “When it says it is going to do something, it usually does.” He said the US and Australia were banking on selling coal to China but that this “doesn’t add up”.

Jeremy Grantham, a billionaire fund manager who oversees $106bn of assets, said his company was on the verge of pulling out of all coal and unconventional fossil fuels, such as oil from tar sands. “The probability of them running into trouble is too high for me to take that risk as an investor.” He said: “If we mean to burn all the coal and any appreciable percentage of the tar sands, or other unconventional oil and gas then we’re cooked. [There are] terrible consequences that we will lay at the door of our grandchildren.”

Segue o Seco (Rolling Stone)

Enquanto a Bahia sofre com “a pior seca dos últimos 50 anos”, os habitantes do sertão se desdobram para superar os percalços. A esperança persiste, mas é minguada como a água da chuva

Por MAÍRA KUBÍK MANO

“Para o carro! para o carro! olha ali, em cima das pedras! Tá vendo?” Não, eu não via nada. A paisagem parecia exatamente a mesma da última meia hora. Toda cor de terra, com uma ou outra catingueira no horizonte e os mandacarus, sempre em maior número, acompanhando o traçado da estrada de chão. “Lembra da cena em que o Fabiano vai tentar pegar um preá? Olha ali!”, o interlocutor insiste, apontando. Vidro abaixado, olhos a postos. Dois bichos pequenos, amarronzados e amendoados, de focinho pontudo, se mexem e se fazem notar. Pronto, lá estão os preás. Júlio César Santos fica satisfeito. Afinal, ele fora parar no sertão justamente depois de ler Vidas Secas.

“Eu sou da Zona da Mata, mas quando li Graciliano Ramos quis vir para cá”, conta Santos, um engenheiro agrônomo que se encantou pela caatinga quando ainda era estudante da Universidade Federal do Recôncavo Baiano (UFRB). Hoje, é chefe do escritório da EBDA (Empresa Baiana de Desenvolvimento Agrícola) em Ipirá, um dos 258 municípios da Bahia em situação de emergência por causa da seca. Junto com outros 17 órgãos e secretarias do governo de Jaques Wagner (PT), a EDBA faz parte do Comitê Estadual de Ações de Convivência com a Seca.

Estamos a caminho da cidade vizinha, Pintadas, onde a estiagem é ainda mais crítica. No percurso, cruzamos quatro rios. Três deles, secos. O céu nublado ao longe parece o prenúncio da mudança. Um chuvisco havia caído naquela madrugada, algo que não acontecia há muito tempo. As marcas ainda estavam na terra, em alguns sulcos rasos que provavelmente abrigaram fios de água corrente. Santos parece aliviado. “Agora precisa chover mais”, diz.

Em uma curva à esquerda surge a casa de Messias e Ginalva Jesus Pereira. A plantação de palmas logo se destaca da monocromia – é verde-escura, com nenhum tom de marrom. Na seca, o vegetal tem sido fonte de alimento imprescindível para garantir a sobrevivência dos animais, que já não têm mais pasto. “O povo vem, visita, admira. Outros ficam com usura”, fala Ginalva, sobrancelhas levantadas, há cerca de 20 anos vivendo naquele roçado.

Como era de se esperar, a conversa envereda para o clima e as gotas que caíram à noite. “Choveu em Ipirá, foi? Ah, aqui foi só uma neblina”, rebate o pequeno Matheus, filho do meio de Ginalva. “Aqui não chove mesmo há três anos. Perdemos dois bezerros e dois umbuzeiros para a seca. Painho está pedindo a Deus para esse resto de palma pegar”, diz, referindo-se a uma área mais distante da casa, plantada há pouco, onde o verde já está quase desbotando.

O cálculo de Matheus não é exagerado. Geralmente, chove na caatinga entre janeiro e maio, justamente a época do plantio. Em 2012, porém, a água não caiu e um período de estiagem emendou no outro, fazendo desta a maior seca dos últimos 50 anos, segundo a Coordenação de Defesa Civil da Bahia (Cordec). A previsão é que ela se estenda por mais um ou dois anos. “Agora, com a chuva, vai ser outra coisa. Vai mudar tudo”, avalia uma experiente Ginalva. Assim como o protagonista Fabiano da obra de Graciliano Ramos, ela sabe que a caatinga ressuscita.

Na casa dela, canos estrategicamente posicionados aguardam a próxima precipitação para recolher a água em cisternas. Enquanto isso não ocorre, Ginalva mantém, por meio de irrigação artificial, a produção – que inclui também feijão de corda, cebolinha, coentro, mamão, batata-doce e quiabo, além da criação de ovinos, caprinos e bovinos. O poço, recém-construído, foi financiado via Pronaf (Programa Nacional de Fortalecimento da Agricultura Familiar) Emergencial.

Assim como Ginalva, outros 6 mil agricultores da região apresentaram projetos para acessar o Programa. Segundo o Banco do Nordeste do Brasil (BNB), foram liberados R$ 10 milhões do Pronaf Emergencial até janeiro de 2013 para os 17 municípios do entorno de Feira de Santana, entre eles Pintadas e Ipirá. “São pequenos agricultores que você vê aqui, solicitando financiamento para plantar palmas ou fazer aguada para recuperar o pasto”, diz José Wilson Junqueira Queiroz, gerente de negócios do BNB. Em todo o Brasil, entre maio e dezembro de 2012, o governo federal autorizou R$ 656,2 milhões em linhas de crédito emergenciais para atender os atingidos pela seca.

“São essas políticas públicas que estão segurando as famílias no campo”, avalia Jeane de Almeida Santiago. Agrônoma que trabalha em uma ONG chamada Fundação Apaeba, ela presta assistência técnica para os produtores de Pintadas, Ipirá, Riachão do Jacuípe, Pé de Serra, Baixa Grande e Nova Fátima, todas na Bahia. “Antes, tinha muito mais gente que ia para São Paulo e outros estados para fazer migração.”

O relato é de alguém que conhece de perto a situação. Jeane nasceu em Pintadas. Estudou na escola agrícola e saiu para fazer curso técnico em Juazeiro e faculdade no Recôncavo Baiano. Voltou quando se formou, querendo transmitir os conhecimentos aprendidos. Olhos vivos e atentos, ela muda o tom e reavalia sua afirmação: “É, mas este ano muitos jovens estão indo. Com a seca, a rentabilidade das propriedades está zero. E as pessoas não vão ficar aqui sem ter dinheiro. Infelizmente, são obrigadas a sair, de coração partido, para São Paulo em busca de trabalho, ver se conseguem mandar dinheiro para a família que ficou aqui manter o rebanho vivo”.

De fato, o ponto de ônibus de Pintadas estava cheio naquela manhã. A cidade ainda não tem rodoviária e o asfalto que a conecta com o resto do mundo foi inaugurado há apenas um ano, como avisam as placas do governo do estado logo na entrada. Todos aguardavam na calçada o próximo transporte para a capital paulista, malas e parentes em pé, sol a pino. Há cerca de três semanas, Ginalva se despedia ali mesmo do filho mais velho, de 18 anos, que decidiu tentar a vida fora dali. “Me ligou ontem dizendo que já arrumou um emprego numa fábrica. É temporário, mas é um emprego”, ela conta. É a famosa ponte aérea Pintadas-São Paulo.

“O pior é que não temos previsão boa para este ano”, lamenta Jeane. Ela conta que até a palma e o mandacaru, também usados para alimentar o rebanho, começaram a desaparecer, e que a maioria das terras da região está na mão de pequenos agricultores de subsistência ou pecuaristas. “Já faz mais de um ano que o município está dando ração aos animais porque não tem mais pasto. Mas agora a ração esgotou. Você procura e não acha. Quando acha, é um valor que não dá para colocar no orçamento.”

Jeane preocupa-se: “Tem produtores que estão pagando três ou quatro projetos. Vai chegar uma hora que ninguém vai conseguir pegar mais [crédito], de tanto que devem. E aí, não sei como vai ser. Porque a propriedade não está tendo rentabilidade para pagar os empréstimos que já deve. Sem crédito, eu acredito que na zona rural fica impossível.”

“A causa desta seca é a destruição do meio ambiente”, ela sentencia, citando uma pesquisa recente que constata que 90% da mata nativa da região havia desaparecido. “A natureza está respondendo. O território está descoberto. E a partir daí vêm as queimadas. Muitos solos já se perderam ou estão enfraquecidos. O pessoal não tem a cultura de adubar e vão explorando e explorando. Os rios que tínhamos morreram. As nascentes estão desmatadas.”

Em Ipirá, logo ao lado, a realidade é semelhante. No lugar da caatinga, estão os bois. A cena mais comum é ver o gado ou os cavalos amontoados embaixo das poucas árvores que restam para escapar do sol escaldante – cabeça na sombra, lombo de fora. “Ipirá era um município cheio de minifúndios”, explica Orlando Cintra, gerente de Agricultura e Cooperativismo da Prefeitura. “Os grandes criadores começaram a chegar nos anos 1960. Este pessoal comprou a terra barata e empurrou o homem que produzia a batata, a mandioca e a mamona para a periferia daqui ou para São Paulo, Mato Grosso e Paraná.” Outros tantos foram trabalhar no corte da cana-de-açúcar. “Aqui não tinha boi e os pequenos produtores não desmatavam”, continua. “O que criávamos mais era o bode. Foi com a chegada dos grandes fazendeiros que o clima em Ipirá começou a mudar mais rapidamente. Desmataram para plantar capim.”

“A caatinga não é uma área para agropecuária. É para criação de caprinos, ovinos, animais de médio porte. Trouxeram a cultura do Sul, de pecuarista, e todo mundo quis ter fazenda de boi aqui”, completa Meire Oliveira, assessora da Secretaria de Agricultura e Meio Ambiente de Ipirá.

Meire passou a infância na zona rural do município e ainda se lembra do cheiro dessa mata. Conta que, quando criança, fazia burros a partir de umbus: enfiava quatro pedaços de galhinhos na fruta, representando as quatro patas. “Pena que, muitas vezes, quando eu digo para não desmatar, nem meu pai me ouve”, lamenta. Ela parece conhecer todas as plantas da caatinga. Quando encontra um cacto coroa-de-frade, mostra que é possível comer seu fruto, pequenino e vermelho. Caminhando pelas propriedades da região, cruza as cercas de arame farpado com desenvoltura. Pega um punhado de maxixe ainda verde e explica como cozinhá-lo. “Igualzinho a quiabo, sabe?” No sertão, tudo pode ser aproveitado. “A caatinga tem um poder de regeneração incrível”, explica. “A solução seria deixá-la descansar. Algumas áreas no entorno do Rio do Peixe já estão em processo de desertificação.”

Um exemplo de preservação ambiental é o assentamento D. Mathias, que completou sete anos de existência. Ali, a caatinga aos poucos renasce entre bodes, cabras e ovelhas. As árvores são podadas apenas o suficiente para não machucarem os animais, que circulam livremente pelas aroeiras, xique-xiques e umbuzeiros. Organizado pelo Movimento Luta Camponesa (MLC), o símbolo do assentamento é uma família de retirantes desenhada em preto e vermelho. A fila é puxada por uma mulher com uma foice nas mãos. Em seguida vem um homem, com uma enxada nos ombros. Dois filhos, um menino e uma menina seguem-nos de mãos dadas. Por último, um cachorro que, quiçá, se chama Baleia.

Júlio César Santos, dirigente da EBDA, presta assistência aos assentados e explica que os camponeses estão muito atentos às políticas públicas e linhas de crédito oferecidas pelos governos estadual e federal. Com isso, já conseguiram construir casas, comprar uma resfriadeira de leite e ampliar a criação de ovelhas. Entre as últimas iniciativas no local está a plantação adensada de palmas, mais rentável do que a tradicional. Em um primeiro momento, os agricultores não confiaram na técnica e continuaram plantando os cactos distantes uns dos outros, como sempre fizeram. Para contornar as dificuldades, Santos utilizou o “método de Paulo Freire”. Plantou dois roçados: de um lado, as palmas, adensadas; de outro, as tradicionais. Agora, as duas estão crescendo e ele espera, em breve, provar sua teoria. “Tomara que a falta de chuva não queime elas”, diz.

O sucesso do assentamento motivou, há 11 meses, um acampamento no latifúndio vizinho. Leidinaura Souza Santana, ou simplesmente Leila, é uma das moradoras do acampamento Elenaldo Teixeira. “O problema maior aqui é a água para beber e cozinhar. Ficamos quase 15 dias sem água. O caminhão-pipa chegou só ontem”, reclama. “A Embasa [Empresa Baiana de Águas e Saneamento] suspendeu o pipa por causa do rio, que já estava muito baixo, e também porque deu um problema na bomba”, explica Meire, que acompanha a visita. “Tivemos que tomar uma água que não é boa para beber”, murmura Leila.

Leila nasceu em Coração de Maria, ao norte de Feira de Santana. O marido trabalhava como vaqueiro em Malhador, povoado no município de Ipirá, quando souberam dos boatos da ocupação. Vieram logo participar. “Estamos esperando chegar a hora para entrar dentro da fazenda e acabar com o sofrimento. A área já foi atestada como improdutiva. O assentamento aqui do lado é uma maravilha. Me animei de ver que esse pessoal era acampado como a gente. Não desisto, não”, afirma. Meire aproveita para dar uma injeção de ânimo: “Eu acompanhei o outro acampamento desde o começo e era igualzinho. Acho que era até mais quente que este. Este é mais fresco. E olha como estão hoje”.

A conversa acontece na escola do acampamento, onde jovens e adultos são alfabetizados. A pequena construção de palha e madeira da escola fica no início daquela que foi batizada de “Avenida Brasil”, uma sequência bem aprumada de cerca de 15 barracos de lona. Leila acabou de passar para a 4a série do ensino fundamental e soletra o nome para mim. “L-E-I-D-I-N-A-U-R-A.” “Não é com ‘l’, não?”, pergunta Meire. “Não, é com ‘u’ mesmo”, Leila responde.

Em Tamanduá, povoado do entorno de Ipirá, motos e jegues passam com gente e baldes na garupa. Tudo lembra a estiagem. Egecivaldo Oliveira Nunes está à beira da estrada, ao volante do caminhão-pipa estacionado em frente à casa azul e branca. “Só trabalho particular, não trabalho com Exército nem Prefeitura. Pegamos água das barragens porque os açudes estavam secos”, ele conta, afirmando que nos piores dias da seca não “acha tempo” para as entregas solicitadas. O pagamento é por distância, e a cada quilômetro rodado muda o valor: 5 quilômetros são equivalentes a 9 mil litros e custam R$ 80. Quem não puder pagar (como os acampados) pode esperar pela Defesa Civil estadual – que afirma ter investido R$ 4 milhões em caminhões-pipa – ou pelo Exército, que mensalmente abastece de água 137 municípios.

“A cada ano, a seca vem mais intensa e a tendência é sempre durar mais”, lamenta Orlando Cintra, gerente de Agricultura e Cooperativismo de Ipirá. “A perspectiva é a de que em cinco ou seis anos ninguém vá produzir mais nada aqui, na área da agricultura. O clima vem se transformando. A cada ano piora.”

“Já tivemos tantas previsões, e nada”, diz Jeane Santiago. “Passa a previsão de chuva no jornal e as pessoas dizem: ‘Não tenho mais fé, só acredito se eu vir’. O pessoal da zona rural tem simpatias, como ‘se a flor do mandacaru desabrochar é sinal de que vai chover’. Mas todas deram errado até agora. A fé está acabando.” Os mandacarus já florearam. O vermelho-forte chama atenção. Agora é esperar.

Historic First Weather Satellite Image (Discovery)

By Tom Yulsman | April 2, 2013 7:46 pm

The first image ever transmitted back to Earth from a weather satellite. It was captured by TIROS-1. (Image: CIMSS Satellite Blog)

The awesome folks over at the satellite blog of the Cooperative Institute for Meteorological Satellite Studies posted this historic image yesterday — and I just couldn’t let it go without giving it more exposure.

The first weather satellite image ever, it was captured by TIROS-1 on April 1, 1960 — meaning yesterday was the 53rd anniversary of the event.

Okay, that may not be as significant as, say, the 50th anniversary was. But this is still a great opportunity to see how far we’ve come with remote sensing of the home planet.

On the same day that the satellite sent back this image, the U.S. Census Bureau determined that the resident population of the United States was 179,245,000. As I write this post, the bureau estimates the population to be 315,602,806. (By the time you read this, the population will be even larger!)

Thanks in part to the pioneering efforts of TIROS-1, and weather satellites that followed, today we have access to advanced warming of extreme events like hurricanes — a capability that has saved many lives.

“TIROS” stands for Television Infrared Observation Satellite Program. Here’s how NASA describes its mission:

The TIROS Program . . . was NASA’s first experimental step to determine if satellites could be useful in the study of the Earth. At that time, the effectiveness of satellite observations was still unproven. Since satellites were a new technology, the TIROS Program also tested various design issues for spacecraft: instruments, data and operational parameters. The goal was to improve satellite applications for Earth-bound decisions, such as “should we evacuate the coast because of the hurricane?”.

Here is the second image taken by Tiros-1 — 53 years ago today:

Tiros-1 transmitted a second weather image on April 2, 1960, 53 years ago today.

Head over to the CIMSS satellite blog for more details. The post there includes  spectacular comparison images from the SUOMI NPP satellite of the same general area: Maine and the Canadian Maritime provinces. One of them is a “visual image at night,” meaning it was shot under moonlight. You can see the sparkling lights of cities.

It was never going to be easy to face the ecological crisis.  Even back in the 1970s, before climate took center stage, it was clear that we the prosperous were walking far too heavily.  And that “environmentalism,” as it was called, was only going to be a small beginning.  But it was only when the climate crisis pushed fossil energy into the spotlight that the real stakes were widely recognized.  Fossil fuels are the meat and potatoes of industrial civilization, and the need to rapidly and radically reduce their emissions cut right through to the heart of the great American dream.  And the European dream.  And, inevitably, the Chinese dream as well.

Decades later, 81% of global energy is still supplied by the fossil fuels: coal, gas, and oil.[1]  And though the solar revolution is finally beginning, the day is late.  The Arctic is melting, and, soon, as each year the northern ocean lies bare beneath the summer sun, the warming will accelerate.  Moreover, our plight is becoming visible.  We have discovered, to our considerable astonishment, that most of the fossil fuel on the books of our largest corporations is “unburnable” – in the precise sense that, if we burn it, we are doomed.[2]  Not that we know what to do with this rather strange knowledge.  Also, even as China rises, it’s obvious that it’s not the last in line for the promised land.  Billions of people, all around the world, watch the wealthy on TV, and most all of them want a drink from the well of modern prosperity.  Why wouldn’t they?  Life belongs to us all, as does the Earth.

The challenge, in short, is rather daunting.

The denial of the challenge, on the other hand, always came ready-made.  As Francis Bacon said so long ago, “what a man would rather were true, he more readily believes.”  And we really did want to believe that ours was still a boundless world.  The alternative – an honest reckoning – was just too challenging.  For one thing, there was no obvious way to reconcile the Earth’s finitude with the relentless expansion of the capitalist market.  And as long as we believed in a world without limits, there was no need to see that economic stratification would again become a fatal issue.  Sure, our world was bitterly riven between haves and have-nots, but this problem, too, would fade in time.  With enough growth – the universal balm – redistribution would never be necessary.  In time, every man would be a king.

The denial had many cheerleaders.  The chemical-company flacks who derided Rachel Carson as a “hysterical woman” couldn’t have known that they were pioneering a massive trend.  Also, and of course, big money always has plenty of mouthpieces.  But it’s no secret that, during the 20th Century, the “engineering of consent” reached new levels of sophistication.  The composed image of benign scientific competence became one of its favorite tools, and somewhere along the way tobacco-industry science became a founding prototype of anti-environmental denialism.  On this front, I’m happy to say that the long and instructive history of today’s denialist pseudo-science has already been expertly deconstructed.[3]  Given this, I can safely focus on the new world, the post-Sandy world of manifest climatic disruption in which the denialists have lost any residual aura of scientific legitimacy, and have ceased to be a decisive political force.  A world in which climate denialism is increasingly seen, and increasingly ridiculed, as the jibbering of trolls.

To be clear, I’m not claiming that the denialists are going to shut up anytime soon.  Or that they’ll call off their suicidal, demoralizing campaigns.  Or that their fogs and poisons are not useful to the fossil-fuel cartel.  But the battle of the science is over, at least as far as the scientists are concerned.  And even on the street, hard denialism is looking pretty ridiculous.  To be sure, the core partisans of the right will fight on, for the win and, of course, for the money.[4]  And they’ll continue to have real weight too, for just as long as people do not believe that life beyond carbon is possible.  But for all this, their influence has peaked, and their position is vulnerable.  They are – and visibly now – agents of a mad and dangerous ideology.  They are knaves, and often they are fools.[5]

As for the rest of us, we can at least draw conclusions, and make plans.

As bad as the human prospect may be – and it is quite bad – this is not “game over.”  We have the technology we need to save ourselves, or most of it in any case; and much of it is ready to go.  Moreover, the “clean tech” revolution is going to be disruptive indeed.  There will be cascades of innovation, delivering opportunities of all kinds, all around the world.  Also, our powers of research and development are strong.  Also, and contrary to today’s vogue for austerity and “we’re broke” political posturing, we have the money to rebuild, quickly and on a global scale.  Also, we know how to cooperate, at least when we have to.  All of which is to say that we still have options.  We are not doomed.

But we are in extremely serious danger, and it is too late to pretend otherwise.  So allow me to tip my hand by noting Jorgen Randers’ new book, 2052: A Global Forecast for the Next Forty Years.[6]  Randers is a Norwegian modeler, futurist, professor, executive, and consultant who made his name as co-author of 1972’s landmark The Limits to Growth.  Limits, of course, was a global blockbuster; it remains the best-selling environmental title of all times.  Also, Limits has been relentlessly ridiculed (the early denialists cut their teeth by distorting it[7]) so it must be said that – very much contrary to the mass-produced opinions of the denialist age – its central, climate-related projections are holding up depressingly well.[8]

By 2012 (when he published 2052) Randers had decided to step away from the detached exploration of multiple scenarios that was the methodological core of Limits, and to make actual predictions.  After a lifetime of frustrated efforts, these predictions are vivid, pessimistic and bitter.  In a nutshell, Randers doesn’t expect anything beyond what he calls “progress as usual,” and while he expects it to yield a “light green” buildout (e.g., solar on a large scale) he doesn’t think it will suffice to stabilize the climate system.  Such stabilization, he grants, is still possible, but it would require concerted global action on a scale that neither he nor Dennis Meadows, the leader of the old Limits team, see on today’s horizon.  Let’s call that kind of action global emergency mobilization.  Meadows, when he peers forwards, sees instead “many decades of uncontrolled climatic disruption and extremely difficult decline.”[9]  Randers is more precise, and predicts that we will by 2052 wake to find ourselves on a dark and frightening shore, knowing full well that our planet is irrevocably “on its way towards runaway climate change in the last third of the twenty-first century.”

This is an extraordinary claim, and it requires extraordinary evidence.[10]  Such evidence, unfortunately, is readily available, but for the moment let me simply state the public secret of this whole discussion.  To wit: we (and I use this pronoun advisedly) can still avoid a global catastrophe, but it’s not at all obvious that we will do so.  What is obvious is that stabilizing the global climate is going to be very, very hard.  Which is a real problem, because we don’t do hard anymore.  Rather, when confronted with a serious problem, we just do what we can, hoping that it will be enough and trying our best not to offend the rich.  In truth, and particularly in America, we count ourselves lucky if we can manage governance at all.

This essay is about climate politics after legitimate skepticism.  Climate politics in a world where, as Leonard Cohen put it, “everybody knows.”  What does this mean?  In the first place, it means that we’ve reached the end of what might be called “environmentalism-as-usual.”  This point is widely understood and routinely granted, as when people say something like “climate is not a merely environmental problem,” but my concern is a more particular one.  As left-green writer Eddie Yuen astutely noted in a recent book on “catastrophism,” the problems of the environmental movement are to a very large degree rooted in “the pairing of overwhelmingly bleak analysis with inadequate solutions.”[11]  This is exactly right.

The climate crisis demands a “new environmentalism,” and such a thing does seem to be emerging.  It’s final shape is unknowable, but one thing is certain – the environmentalism that we need will only exist when its solutions and strategies stand up to its own analyses.  The problem is that this requires us to take our “overwhelmingly bleak” analyses straight, rather than soft-pedaling them so that our “inadequate solutions” might look good.  Pessimism, after all, is closely related to realism.  It cannot just be wished away.

Soft-pedaling, alas, has long been standard practice, on both the scientific and the political sides of the climate movement.  Examples abound, but the best would have to be the IPCC itself, the U.N’s Intergovernmental Panel on Climate Change.  The world’s premier climate-science clearinghouse, the IPCC is often attacked from the right, and has developed a shy and reticent culture.  Even more importantly, though, and far more rarely noted, is that the IPCC is conservative by definition and by design.[12]  It almost has to be conservative to do its job, which is to herd the planet’s decision makers towards scientific realism.  The wrinkle is that, at this point, this isn’t even close to being good enough, not at least in the larger scheme.  At this point, we need strategic realism as well as baseline scientific realism, and it demands a brutal honesty in which underlying scientific and political truths are clearly drawn and publicly expressed.

Yet when it comes to strategic realism, we balk.  The first impulse of the “messaging” experts is always to repeat their perennial caution that sharp portraits of the danger can be frightening, and disempowering, and thus lead to despair and passivity.  This is an excellent point, but it’s only the beginning of the truth, not the end.  The deeper problem is that the physical impacts of climate disruption – the destruction and the suffering – will continue to escalate.  “Superstorm Sandy” was bad, but the future will be much worse.  Moreover, the most severe suffering will be far away, and easy for the good citizens of the wealthy world to ignore.  Imagine, for example, a major failure of the Indian Monsoon, and a subsequent South Asian famine.  Imagine it against a drumbeat background in which food is becoming progressively more expensive.  Imagine the permanence of such droughts, and increasing evidence of tipping points on the horizon, and a world in which ever more scientists take it upon themselves to deliver desperate warnings.  The bottom line will not be the importance of communications strategies, but rather the manifest reality, no longer distant and abstract, and the certain knowledge that we are in deep trouble.  And this is where the dangers of soft-pedaling lie.  For as people come to see the scale of the danger, and then to look about for commensurate strategies and responses, the question will be if such strategies are available, and if they are known, and if they are plausible.  If they’re not, then we’ll all going, together, down the road “from aware to despair.”

Absent the public sense of a future in which human resourcefulness and cooperation can make a decisive difference, we assuredly face an even more difficult future in which denial fades into a sense of pervasive hopelessness.  The last third of the century (when Randers is predicting “runaway climate change”) is not so very far away.  Which is to say that, as denialism collapses – and it will – the challenge of working out a large and plausible response to the climate crisis will become overwhelmingly important.  If we cannot imagine such a response, and explain how it would actually work, then people will draw their own conclusions.  And, so far, it seems that we cannot.  Even those of us who are now climate full-timers don’t have a shared vision, not in any meaningful detail, nor do we have a common sense of the strategic initiatives that could make such a vision cohere.

The larger landscape is even worse.  For though many scientists are steeling themselves to speak, the elites themselves are still stiff and timid, and show few signs of rising to the occasion.  Each month, it seems, there’s another major report on the approaching crisis – the World Bank, the National Intelligence Council, and the International Energy Agency have all recently made hair-raising contributions – but they never quite get around to the really important questions.  How should we contrive the necessary global mobilization?  What conditions are needed to absolutely maximize the speed of the clean-tech revolution?  By what strategy will we actually manage to keep the fossil-fuels in the ground?  What kind of international treaties are necessary, and how shall we establish them?  What would a fast-enough global transition cost, and how shall we pay for it?  What about all those who are forced to retreat from rising waters and drying lands?  How shall they live, and where?  How shall we talk about rights and responsibilities in the Greenhouse Century?  And what about the poor?  How shall they find futures in a climate-constrained world?  Can we even imagine a world in which they do?

In the face of such questions, you have a choice.  You can conclude that we’ll just have to do the best we can, and then you can have a drink.  Or maybe two.  Or you can conclude that, despite all evidence to the contrary, enough of us will soon awaken to reality.  What’s certain is that, all around us, there is a vast potentiality – for reinvention, for resistance, for redistribution, and for renewal of all kinds – and that it could at any time snap into solidity.  And into action.

Forget about “hope.”  What we need now is intention.

***

About a decade ago, in San Francisco, I was on a PBS talk show with, among others, Myron Ebell, chief of climate propaganda at the Competitive Enterprise Institute.  Ebell is an aggressive professional, and given the host’s commitment to phony balance he was easily able to frame the conversation.[13]  The result was a travesty, but not an entirely wasted time, at least not for me.  It was instructive to speak, tentatively, of the need for global climate justice, and to hear, in response, that I was a non-governmental fraud that was only in it for the money.  Moreover, as the hour wore on, I came to appreciate the brutal simplicity of the denialist strategy.  The whole point is to suck the oxygen out of the room, to weave such a tangle of confusionism and pseudo-debate that the Really Big Question – What is to be done? – becomes impossible to even ask, let alone discuss.

When Superstorm Sandy slammed into the New York City region, Ebell’s style of hard denialism took a body blow, though obviously it has not dropped finally to the mat.  Had it done do, the Big Question, in all its many forms, would be buzzing constantly around us.  Clearly, that great day has not yet come.  Still, back in November of 2012, when Bloomberg’s Business Week blared “It’s Global Warming, Stupid” from its front cover, this was widely welcomed as a overdue milestone.  It may even be that Michael Tobis, the editor of the excellent Planet 3.0, will prove correct in his long-standing, half-facetious prediction that 2015 will be the date when “the Wall Street Journal will acknowledge the indisputable and apparent fact of anthropogenic climate change; the year in which it will simply be ridiculous to deny it.”[14]  Or maybe not.  Maybe that day will never come.  Maybe Ebell’s style of well-funded, front-group denialism will live on, zombie-like, forever.  Or maybe (and this is my personal prediction) hard climate denialism will soon go the way of creationism and far-right Christianity, becoming a kind of political lifestyle choice, one that’s dangerous but contained.  One that’s ultimately more dangerous to the right than it is to the reality-based community.

If so, then at some point we’re going to have to ask ourselves if we’ve been so long distracted by the hard denialists that we’ve missed the parallel danger of a “soft denialism.”  By which I mean the denialism of a world in which, though the dangers of climate change are simply too ridiculous to deny, they still – somehow – are not taken to imply courage, and reckoning, and large-scale mobilization.  This is a long story, but the point is that, now that the Big Question is finally on the table, we’re going to have to answer it.  Which is to say that we’re going to have to face the many ways in which political timidity and small-bore realism have trained us to calibrate our sense of what must be done by our sense of what can be done, which these days is inadequate by definition.

And not just because of the denialists.

George Orwell once said that “To see what is in front of one’s nose needs a constant struggle.”[15]  As we hurtle forward, this struggle will rage as never before.  The Big Question, after all, changes everything.  Another way of saying this is that our futures will be shaped by the effort to avoid a full-on global climate catastrophe.  Despite all the rest of the geo-political and geo-economic commotion that will mark the 21st Century (and there’ll be plenty) it will be most fundamentally the Greenhouse Century.  We know this now, if we care to, though still only in preliminary outline.  The details, inevitably, will surprise us all.

The core problem, of course, will be “ambition” – action on the scale that’s actually necessary, rather than the scale that is or appears to be possible.  And here, the legacies of the denialist age – the long-ingrained habits of soft-pedaling and strained optimism – will weigh heavily.  Consider the quasi-official global goal (codified, for example, in the Copenhagen Accord) to hold total planetary warming to 2°C (Earth surface average) above pre-industrial levels.  This is the so-called “2°C target.”  What are we to do with it in the post-denialist age?  Let me count the complications: One, all sorts of Very Important People are now telling us it’s going to all but impossible to avoid overshooting 2°C.[16]  Two, in so doing, they are making a political and not a scientific judgment, though they’re not always clear on this point.  (It’s probably still technically possible to hold the 2°C line – if we’re not too unlucky – though it wouldn’t be easy under the best of circumstances.)[17]  Three, the 2°C line, which was once taken to be reasonably safe, is now widely seen (at least among the scientists) to mark the approximate point of transition from “dangerous” to “extremely dangerous,” and possibly to altogether unmanageable levels of warming.[18]  Four, and finally, it’s now widely recognized that any future in which we approach the 2°C line (which we will do) is one in which we also have a real possibility of pushing the average global temperature up by 3°C, and if this were to come to pass we’d be playing a very high-stakes game indeed, one in which uncontrolled positive feedbacks and worst-case scenarios were surrounding us on every side.

The bottom line is today as it was decades ago.  Greenhouse-gas emissions were increasing then, and they are increasing now.  In late 2012, the authoritative Global Carbon Project reported that, since 1990, they had risen by an astonishing 58 percent.[19]  The climate system has unsurprisingly responded with storms, droughts, ice-melt, conflagrations and floods.  The weather has become “extreme,” and may finally be getting our attention.  In Australia, according to the acute Mark Thomson of the Institute for Backyard Studies in Adelaide, the crushing heatwave of early 2013 even pushed aside “the idiot commentariat” and cleared the path for a bit of 11th-hour optimism: “Another year of this trend will shift public opinion wholesale.  We’re used to this sort of that temperature now and then and even take a perverse pride in dealing with it, but there seems to be a subtle shift in mood that ‘This Could Be Serious.’”  Let’s hope he’s right.  Let’s hope, too, that the mood shift that swept through America after Sandy also lasts, and leads us, too, to conclude that ‘This Could Be Serious.’  Not that this alone would be enough to support a real mobilization – the “moral equivalent of war” that we need – but it would be something.  It might even lead us to wonder about our future, and about the influence of money and power on our lives, and to ask how serious things will have to get before it becomes possible to imagine a meaningful change of direction.

The wrinkle is that, before we can advocate for a meaningful change of direction, we have to have one we believe in, one that we’re willing to explain in global terms that actually scale to the problem.  None of which is going to be easy, given that we’re fast approaching a point where only tales of existential danger ring true.  (cf the zombie apocalypse).  The Arctic ice, as noted above, offers an excellent marker.  In fact, the first famous photos of Earth from space – the “blue marble” photos taken in 1972 by the crew of the Apollo 17 – allow us to anchor our predicament in time and in memory.  For these are photos of an old Earth now passed away; they must be, because they show great expanses of ice that are nowhere to be found.  By August of 2012 the Arctic Sea’s ice cover had declined by 40%,[20] a melt that’s easily large enough to be visible from space.  Moreover, beneath the surface, ice volume is dropping even more precipitously.  The polar researchers who are now feverishly evaluating the great melting haven’t yet pushed the entire scientific community to the edge of despair, though they have managed to inspire a great deal of dark muttering about positive feedbacks and tipping points.  Soon, it seems, that muttering will become louder.  Perhaps as early as 2015, the Arctic Ocean will become virtually ice free for the first time in recorded history.[21]  When it does, the solar absorptivity of the Arctic waters will increase, and shift the planetary heat balance by a surprisingly large amount, and by so doing increase the rate of  planetary warming.  And this, of course, will not be end of it.  The feedbacks will continue.  The cycles will go on.

Should we remain silent about such matters, for risk of inflaming the “idiot commentariat?”  It’s absurd to even ask.  The suffering is already high, and if you know the science, you also know that the real surprise would be an absence of positive feedbacks.  The ice melt, the methane plumes, the drying of the rainforests – they’re all real.  Which is to say that there are obviously tipping points before us, though we do not and can not know how much time will pass before they force themselves upon our attention.  The real question is what we must do if we would talk of them in good earnest, while at the same time speaking, without despair and effectively, about the human future.

“If, at the beginning, the debate on LTG had seemed to be balanced, gradually the general attitude on the study became more negative. It tilted decisively against the study when, in 1989, Ronald Bailey published a paper in “Forbes” where he accused the authors of having predicted that the world’s economy should have already run out of some vital mineral commodities whereas that had not, obviously, occurred.

Bailey’s statement was only the result of a flawed reading of the data in a single table of the 1972 edition of LTG. In reality, none of the several scenarios presented in the book showed that the world would be running out of any important commodity before the end of the twentieth century and not even of the twenty-first. However, the concept of the “mistakes of the Club of Rome” caught on. With the 1990s, it became commonplace to state that LTG had been a mistake if not a joke designed to tease the public, or even an attempt to force humankind into a planet-wide dictatorship, as it had been claimed in some earlier appraisals (Golub and Townsend 1977; Larouche 1983). By the end of the twentieth century, the victory of the critics of LTG seemed to be complete. But the debate was far from being settled.”

[17] I just wrote “probably still technically possible.”  I could have written “Excluding the small probability of a very bad case, and the even smaller probability of a very good case, it’s probably still technically possible to hold the 2°C line, though it wouldn’t be easy.”  This, however, is a pretty ugly sentence.  I could also have written “Unless we’re unlucky, and the climate sensitivity turns out be on the high side of the expected range, it’s still technically possible to hold the 2°C line, though it wouldn’t be easy, unless we’re very lucky, and the climate sensitivity turns out to be on the low side.”  Saying something like this, though, kind of puts the cart before the horse, since I haven’t said anything about “climate sensitivity,” or about how the scientists think about probability – and of course it’s even uglier.  The point, at least for now, is that climate projections are probabilistic by nature, which does not mean that they are merely “uncertain.”  We know a lot about the probabilities.

Climate Maverick to Retire From NASA (N.Y.Times)

Michael Nagle for The New York Times. James E. Hansen of NASA, retiring this week, reflected in a window at his farm in Pennsylvania.

By 

Published: April 1, 2013

His departure, after a 46-year career at the space agency’s Goddard Institute for Space Studies in Manhattan, will deprive federally sponsored climate research of its best-known public figure.

At the same time, retirement will allow Dr. Hansen to press his cause in court. He plans to take a more active role in lawsuits challenging the federal and state governments over their failure to limit emissions, for instance, as well as in fighting the development in Canada of a particularly dirty form of oil extracted from tar sands.

“As a government employee, you can’t testify against the government,” he said in an interview.

Dr. Hansen had already become an activist in recent years, taking vacation time from NASA to appear at climate protests and allowing himself to be arrested or cited a half-dozen times.

But those activities, going well beyond the usual role of government scientists, had raised eyebrows at NASA headquarters in Washington. “It was becoming clear that there were people in NASA who would be much happier if the ‘sideshow’ would exit,” Dr. Hansen said in an e-mail.

At 72, he said, he feels a moral obligation to step up his activism in his remaining years.

“If we burn even a substantial fraction of the fossil fuels, we guarantee there’s going to be unstoppable changes” in the climate of the earth, he said. “We’re going to leave a situation for young people and future generations that they may have no way to deal with.”

His departure, on Wednesday, will end a career of nearly half a century working not just for a single agency but also in a single building, on the edge of the Columbia University campus.

From that perch, seven floors above the diner made famous by “Seinfeld,” Dr. Hansen battled the White House, testified dozens of times in Congress, commanded some of the world’s most powerful computers and pleaded with ordinary citizens to grasp the basics of a complex science.

His warnings and his scientific papers have drawn frequent attack from climate-change skeptics, to whom he gives no quarter. But Dr. Hansen is a maverick, just as likely to vex his allies in the environmental movement. He supports nuclear power and has taken stands that sometimes undercut their political strategy in Washington.

In the interview and in subsequent e-mails, Dr. Hansen made it clear that his new independence would allow him to take steps he could not have taken as a government employee. He plans to lobby European leaders — who are among the most concerned about climate change — to impose a tax on oil derived from tar sands. Its extraction results in greater greenhouse emissions than conventional oil.

Dr. Hansen’s activism of recent years dismayed some of his scientific colleagues, who felt that it backfired by allowing climate skeptics to question his objectivity. But others expressed admiration for his willingness to risk his career for his convictions.

Initially, Dr. Hansen plans to work out of a converted barn on his farm in Pennsylvania. He has not ruled out setting up a small institute or taking an academic appointment.

He said he would continue publishing scientific papers, but he will no longer command the computer time and other NASA resources that allowed him to track the earth’s rising temperatures and forecast the long-run implications.

Dr. Hansen, raised in small-town Iowa, began his career studying Venus, not the earth. But as concern arose in the 1970s about the effects of human emissions of greenhouse gases, he switched gears, publishing pioneering scientific papers.

His initial estimate of the earth’s sensitivity to greenhouse gases was somewhat on the high side, later work showed. But he was among the first scientists to identify the many ways the planet is likely to respond to rising temperatures and to show how those effects would reinforce one another to produce immense changes in the climate and environment, including a sea level rise that could ultimately flood many of the world’s major cities.

“He’s done the most important science on the most important question that there ever was,” said Bill McKibben, a climate activist who has worked closely with Dr. Hansen.

Around the time Dr. Hansen switched his research focus, in the 1970s, a sharp rise in global temperatures began. He labored in obscurity over the next decade, but on a blistering June day in 1988 he was called before a Congressional committee and testifiedthat human-induced global warming had begun.

Speaking to reporters afterward in his flat Midwestern accent, he uttered a sentence that would appear in news reports across the land: “It is time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here.”

Given the natural variability of climate, it was a bold claim to make after only a decade of rising temperatures, and to this day some of his colleagues do not think he had the evidence.

Yet subsequent events bore him out. Since the day he spoke, not a single month’s temperatures have fallen below the 20th-century average for that month. Half the world’s population is now too young to have lived through the last colder-than-average month, February 1985.

In worldwide temperature records going back to 1880, the 19 hottest years have all occurred since his testimony.

Again and again, Dr. Hansen made predictions that were ahead of the rest of the scientific community and, arguably, a bit ahead of the evidence.

“Jim has a real track record of being right before you can actually prove he’s right with statistics,” said Raymond T. Pierrehumbert, a planetary scientist at the University of Chicago.

Dr. Hansen’s record has by no means been spotless. Even some of his allies consider him prone to rhetorical excess and to occasional scientific error.

He has repeatedly called for trying the most vociferous climate-change deniers for “crimes against humanity.” And in recent years, he stated that excessive carbon dioxide emissions might eventually lead to a runaway greenhouse effect that would boil the oceans and render earth uninhabitable, much like Venus.

His colleagues pointed out that this had not happened even during exceedingly warm episodes in the earth’s ancient past. “I have huge respect for Jim, but in this particular case, he overstated the risk,” said Daniel P. Schrag, a geochemist and the head of Harvard’s Center for the Environment, who is nonetheless deeply worried about climate change.

Climate skeptics have routinely accused Dr. Hansen of alarmism. “He consistently exaggerates all the dangers,” Freeman Dyson, the famed physicist and climate contrarian,told The New York Times Magazine in 2009.

Perhaps the biggest fight of Dr. Hansen’s career broke out in late 2005, when a young political appointee in the administration of George W. Bush began exercising control over Dr. Hansen’s statements and his access to journalists. Dr. Hansen took the fight public and the administration backed down.

For all his battles with conservatives, however, he has also been hard on environmentalists. He was a harsh critic of a failed climate bill they supported in 2009, on the grounds that it would have sent billions into the federal government’s coffers without limiting emissions effectively.

Dr. Hansen agrees that a price is needed on carbon dioxide emissions, but he wants the money returned to the public in the form of rebates on tax bills. “It needs to be done on the basis of conservative principles — not one dime to make the government bigger,” said Dr. Hansen, who is registered as a political independent.

In the absence of such a broad policy, Dr. Hansen has been lending his support to fights against individual fossil fuel projects. Students lured him to a coal protest in 2009, and he was arrested for the first time. That fall he was cited again after sleeping overnight in a tent on the Boston Common with students trying to pressure Massachusetts into passingclimate legislation.

“It was just humbling to have that solidarity and support from this leader, this lion among men,” said Craig S. Altemose, an organizer of the Boston protest.

Dr. Hansen says he senses the beginnings of a mass movement on climate change, led by young people. Once he finishes his final papers as a NASA employee, he intends to give it his full support.

“At my age,” he said, “I am not worried about having an arrest record.”

Survey Shows Many Republicans Feel America Should Take Steps to Address Climate Change (Science Daily)

Apr. 2, 2013 — In a recent survey of Republicans and Republican-leaning Independents conducted by the Center for Climate Change Communication (4C) at George Mason University, a majority of respondents (62 percent) said they feel America should take steps to address climate change. More than three out of four survey respondents (77 percent) said the United States should use more renewable energy sources, and of those, most believe that this change should begin immediately.

The national survey, conducted in January 2013, asked more than 700 people who self-identified as Republicans and Republican-leaning Independents about energy and climate change.

“Over the past few years, our surveys have shown that a growing number of Republicans want to see Congress do more to address climate change,” said Mason professor Edward Maibach, director of 4C. “In this survey, we asked a broader set of questions to see if we could better understand how Republicans, and Independents who have a tendency to vote Republican, think about America’s energy and climate change situation.”

Other highlights from the survey include the following:

  • Republicans and Republican-leaning Independents prefer clean energy as the basis of America’s energy future and say the benefits of clean energy, such as energy independence (66 percent) saving resources for our children and grandchildren (57 percent), and providing a better life for our children and grandchildren (56 percent) outweigh the costs, such as more government regulation (42 percent) or higher energy prices (31 percent).
  • By a margin of 2 to 1, respondents say America should take action to reduce its fossil fuel use.
  • Only one third of respondents agree with the Republican Party’s position on climate change, while about half agree with the party’s position on how to meet America’s energy needs.
  • A large majority of respondents say their elected representatives are unresponsive to their views about climate change.

“The findings from this survey suggest there is considerable support among conservatives for accelerating the transition away from fossil fuels and toward clean renewable forms of energy, and for taking steps to address climate change,” said Maibach. “Perhaps the most surprising finding, however, is how few of our survey respondents agreed with the Republican Party’s current position on climate change.”

The report can be downloaded at: http://climatechangecommunication.org

The report is based on findings from a nationally representative survey conducted by the George Mason University Center for Climate Change Communication. A total of 726 adults (18+) were interviewed between January 12th and January 27th, 2013. The average margin of error for the survey +/- 4 percentage points at the 95% confidence level.

Statistical Physics Offers a New Way to Look at Climate (Science Daily)

Mar. 5, 2013 — Statistical physics offers an approach to studying climate change that could dramatically reduce the time and brute-force computing that current simulation techniques require. The new approach focuses on fundamental forces that drive climate rather than on “following every little swirl” of water or air.

Two views, two approaches to simulation. Computer-generated images of a planet’s “zonal velocity” (the west-to-east component of wind) use direct numerical simulation (the traditional approach, left) and direct statistical simulation. The latter has limits, but its development is at a very early stage. (Credit: Marston lab/Brown University)

Scientists are using ever more complex models running on ever more powerful computers to simulate Earth’s climate. But new research suggests that basic physics could offer a simpler and more meaningful way to model key elements of climate.

The research, published in the journal Physical Review Letters, shows that a technique called direct statistical simulation does a good job of modeling fluid jets, fast-moving flows that form naturally in oceans and in the atmosphere. Brad Marston, professor of physics at Brown University and one of the authors of the paper, says the findings are a key step toward bringing powerful statistical models rooted in basic physics to bear on climate science.

In addition to the Physical Review Letters paper, Marston will report on the work at a meeting of the American Physical Society to be held in Baltimore this later month.

The method of simulation used in climate science now is useful but cumbersome, Marston said. The method, known as direct numerical simulation, amounts to taking a modified weather model and running it through long periods of time. Moment-to-moment weather — rainfall, temperatures, wind speeds at a given moment, and other variables — is averaged over time to arrive at the climate statistics of interest. Because the simulations need to account for every weather event along the way, they are mind-bogglingly complex, take a long time run, and require the world’s most powerful computers.

One practical advantage of the new approach: the ability to model climate conditions from millions of years ago without having to reconstruct the world’s entire weather history.Direct statistical simulation, on the other hand, is a new way of looking at climate. “The approach we’re investigating,” Marston said, “is the idea that one can directly find the statistics without having to do these lengthy time integrations.”

It’s a bit like the approach physicists use to describe the behavior of gases.

“Say you wanted to describe the air in a room,” Marston said. “One way to do it would be to run a giant supercomputer simulation of all the positions of all of the molecules bouncing off of each other. But another way would be to develop statistical mechanics and find that the gas actually obeys simple laws you can write down on a piece of paper: PV=nRT, the gas equation. That’s a much more useful description, and that’s the approach we’re trying to take with the climate.”

Conceptually, the technique focuses attention on fundamental forces driving climate, instead of “following every little swirl,” Marston said. A practical advantage would be the ability to model climate conditions from millions of years ago without having to reconstruct the world’s entire weather history in the process.

The theoretical basis for direct statistical simulation has been around for nearly 50 years. The problem, however, is that the mathematical and computational tools to apply the idea to climate systems aren’t fully developed. That is what Marston and his collaborators have been working on for the last few years, and the results in this new paper show their techniques have good potential.

The paper, which Marston wrote with University of Leeds mathematician Steve Tobias, investigates whether direct statistical simulation is useful in describing the formation and characteristics of fluid jets, narrow bands of fast-moving fluid that move in one direction. Jets form naturally in all kinds of moving fluids, including atmospheres and oceans. On Earth, atmospheric jet streams are major drivers of storm tracks.

For their study, Marston and Tobias simulated the jets that form as a fluid moves on a hypothetical spinning sphere. They modeled the fluid using both the traditional numerical technique and their statistical technique, and then compared the output of the two models. They found that the models generally arrived at similar values for the number of jets that would form and the strength of the airflow, demonstrating that statistical simulation can indeed be used to model jets.

There were limits, however, to what the statistical model could do. The study found that as pace of adding and removing energy to the fluid system increased, the statistical model started to break down. Marston and Tobias are currently working on an expansion of their technique to deal with that problem.

Despite the limitation, Marston is upbeat about the potential for the technique. “We’re very pleased that it works as well as it did here,” he said.

Since completing the study, Marston has integrated the method into a computer program called “GCM” that he has made easily available via Apple’s Mac App Store for other researchers to download. The program allows users to build their own simulations, comparing numerical and statistical models. Marston expects that researchers who are interested in this field will download it and play with the technique on their own, providing new insights along the way. “I’m hoping that citizen-scientists will also explore climate modeling with it as well, and perhaps make a discovery or two,” he said.

There’s much more work to be done on this, Marston stresses, both in solving the energy problem and in scaling the technique to model more realistic climate systems. At this point, the simulations have only been applied to hypothetical atmospheres with one or two layers. Earth’s atmosphere is a bit more complex than that.

“The research is at a very early stage,” Marston said, “but it’s picking up steam.”

Ten Times More Hurricane Surges in Future, New Research Predicts (Science Daily)

Mar. 18, 2013 — By examining the frequency of extreme storm surges in the past, previous research has shown that there was an increasing tendency for storm hurricane surges when the climate was warmer. But how much worse will it get as temperatures rise in the future? How many extreme storm surges like that from Hurricane Katrina, which hit the U.S. coast in 2005, will there be as a result of global warming? New research from the Niels Bohr Institute show that there will be a tenfold increase in frequency if the climate becomes two degrees Celcius warmer.

The results are published in the scientific journal, Proceedings of the National Academy of Science,PNAS.

Tropical cyclones arise over warm ocean surfaces with strong evaporation and warming of the air. The typically form in the Atlantic Ocean and move towards the U.S. East Coast and the Gulf of Mexico. If you want to try to calculate the frequency of tropical cyclones in a future with a warmer global climate, researchers have developed various models. One is based on the regional sea temperatures, while another is based on differences between the regional sea temperatures and the average temperatures in the tropical oceans. There is considerable disagreement among researchers about which is best.

New model for predicting cyclones

“Instead of choosing between the two methods, I have chosen to use temperatures from all around the world and combine them into a single model,” explains climate scientist Aslak Grinsted, Centre for Ice and Climate at the Niels Bohr Institute at the University of Copenhagen.

He takes into account the individual statistical models and weights them according to how good they are at explaining past storm surges. In this way, he sees that the model reflects the known physical relationships, for example, how the El Niño phenomenon affects the formation of cyclones. The research was performed in collaboration with colleagues from China and England.

The statistical models are used to predict the number of hurricane surges 100 years into the future. How much worse will it be per degree of global warming? How many ‘Katrinas’ will there be per decade?

Since 1923, there has been a ‘Katrina’ magnitude storm surge every 20 years.

10 times as many ‘Katrinas’

“We find that 0.4 degrees Celcius warming of the climate corresponds to a doubling of the frequency of extreme storm surges like the one following Hurricane Katrina. With the global warming we have had during the 20th century, we have already crossed the threshold where more than half of all ‘Katrinas’ are due to global warming,” explains Aslak Grinsted.

“If the temperature rises an additional degree, the frequency will increase by 3-4 times and if the global climate becomes two degrees warmer, there will be about 10 times as many extreme storm surges. This means that there will be a ‘Katrina’ magnitude storm surge every other year,” says Aslak Grinsted and he points out that in addition to there being more extreme storm surges, the sea will also rise due to global warming. As a result, the storm surges will become worse and potentially more destructive.

É preciso insistir e insistir: as grandes cidades brasileiras – mas não apenas elas – precisam criar com urgência políticas do clima que as habilitem a enfrentar com eficiência os “desastres naturais”, cada vez mais frequentes e intensos e que provocam um número cada vez maior de mortos e outras vítimas; precisam arrancar do fundo das gavetas projetos que permitam evitar inundações em áreas urbanas; criar planos diretores que incorporem as novas informações nessa área; rever os padrões de construção, já obsoletos, concebidos em outras épocas, para condições climáticas muito mais amenas – e que se mostram cada vez mais vulneráveis a desabamentos; incorporar as universidades nessa busca de formatos científicos e tecnológicos.

Segundo este jornal (21/2), de 12 locais alagados em uma semana no mês passado na cidade de São Paulo, 11 já sofriam com inundações há 20 anos – entre eles, alguns dos pontos com mais veículos e pessoas, como o Vale do Anhangabaú, a Avenida 23 de Maio, a Rua Turiaçu. E a Prefeitura de São Paulo promete desengavetar 79 obras antienchentes, algumas delas abafadas há 15 anos. Inacreditável. O governo do Estado assegura que vai trabalhar em 14 piscinões (outros 30 caberão a parcerias público-privadas), além de aplicar mais R$ 317 milhões em desassoreamento do Rio Tietê, onde já foi gasto R$ 1,7 bilhão (terá de gastar muito mais enquanto não decidir atuar nas dezenas de afluentes do rio sob o asfalto, que carregam sedimentos, lixo, esgotos, etc.). A população paulistana ficará muito grata – ela e 1 milhão de pessoas que entram e saem diariamente da cidade (Estado, 27/2).

Enquanto não houver uma ação enérgica na área do clima e na revisão dos padrões de construção em toda parte, continuaremos assim, como nas últimas semanas: obra irregular provoca desabamento de prédio na Liberdade e mata pedestre (1.ª/3); edifício de 20 andares desaba no Rio e arrasta mais dois, com 22 mortos (25/1); desabamento de lajes em construção de 13 pavimentos em São Bernardo do Campo mata duas pessoas (6/2); enchente em fábrica mata quatro em Sorocaba; inundação no Rio mata cinco pessoas (8/3); homem salva três pessoas e morre junto com um estudante, levados pela enxurrada durante temporal de cinco horas no Ipiranga, quando caiu um terço da chuva prevista para o mês e fez transbordar o Tamanduateí (11/3); deslizamento na moderna Rodovia dos Imigrantes mata uma pessoa e interrompe o tráfego (22/2), numa chuva de 183,4 milímetros, algumas vezes mais do que o índice médio de chuvas em um mês na região. Até o Arquivo Nacional, no Rio de Janeiro, perdeu mais de 130 caixas de documentos históricos num temporal no centro da cidade (10/3).

Não pode haver ilusões. O Brasil já está em quinto lugar entre os países que mais têm sofrido com desastres climáticos. O Semiárido, em outubro último, teve o mês mais seco em 83 anos, segundo o Operador Nacional do Sistema Elétrico (Estado, 31/10); 10 milhões de pessoas foram atingidas em mais de 1300 municípios. O Painel Intergovernamental sobre Mudanças Climáticas, órgão da Convenção do Clima, este ano só divulgará parte de seu novo relatório, mas seu secretário-geral, Rajendra Pachauri, já adverte que é preciso “espalhar a preocupação”, de vez que, com o aumento da temperatura, até 2050, entre 2 e 2,4 graus Celsius, o nível dos oceanos se elevará entre 0,4 e 1,4 metro – mas poderá ser mais, com o avanço do degelo no Ártico (Guardian, 28/2).

Não é por acaso, assim, que o sistema escolar público dos Estados Unidos já tenha, este ano, incorporado as questões do clima a seu currículo para os alunos. E que o Conselho da União Europeia tenha aprovado 20% do seu orçamento – ou 960 bilhões – para políticas e ações nessa área. Porque as informações são altamente preocupantes. Como as da Organização das Nações Unidas para a Alimentação e a Agricultura (9/3) de que duplicou, de 1970 para cá, a superfície de terras afetadas pela seca no mundo; ou a de que as emissões de dióxido de carbono CO2 por desmatamento, atividades agrícolas e outros formatos, entre 1990 e 2010, cresceram muito – e o Brasil responde por 25,8 bilhões de toneladas equivalentes de CO2, seguido pela Indonésia (13,1 bilhões de toneladas) e pela Nigéria (3,8 bilhões).

Os problemas com o clima, diz a Universidade de Reading (1.º/3), indicam que será preciso aumentar a produtividade na agricultura em 12% a partir de 2016, para compensar as perdas e as mudanças nos ambientes. A vegetação nas latitudes mais ao norte da América está mudando, começa a assemelhar-se à das áreas mais ao sul, segundo a Nasa (UPI, 12/3), que analisou o período 1982-2011; e lembra que as atividades no campo terão de adaptar-se. Também há alterações muito fortes em outras regiões, como nos Rios Tigre e Eufrates, que em sete anos (2003-2010) perderam 144 quilômetros cúbicos de água, equivalentes ao volume do Mar Morto (O Globo, 14/2).

Em toda parte as informações inquietam. Universidades da Flórida, por exemplo (Huffpost Miami, 12/3), alertam que será preciso transplantar três grandes estações de tratamento de esgotos no sul do Estado para evitar que elas fiquem “confinadas em ilhas” em menos de 50 anos, por causa da elevação do nível do mar. O almirante Samuel J. Locklear III, comandante da frota norte-americana no Pacífico, diz que essa elevação do nível dos oceanos “é a maior ameaça à segurança”. E que China e Índia precisam preparar-se para socorrer e evacuar centenas de milhares ou milhões de pessoas.

Retornando ao início deste artigo: as cidades brasileiras não podem adiar o enfrentamento das mudanças do clima, principalmente quanto a inundações e deslizamentos de terras (o Brasil tem mais de 5 milhões de pessoas em áreas de risco). Segundo a revista New Scientist (20/10/2012), 32 mil pessoas morreram no mundo, entre 2004 e 2010, em eventos dessa natureza (em terremotos, 80 mil). Não faltam avisos.

Obama Will Use Nixon-Era Law to Fight Climate Change (Bloomberg)

By Mark Drajem – Mar 15, 2013 12:50 PM GMT-0300

Daniel Acker/Bloomberg. Similar analyses could be made for the oil sands that would be transported in TransCanada Corp.’s Keystone XL pipeline, and leases to drill for oil, gas and coal on federal lands, such as those for Arch Coal Inc. and Peabody Energy Corp.

President Barack Obama is preparing to tell all federal agencies for the first time that they should consider the impact on global warming before approving major projects, from pipelines to highways.

The result could be significant delays for natural gas- export facilities, ports for coal sales to Asia, and even new forest roads, industry lobbyists warn.

“It’s got us very freaked out,” said Ross Eisenberg, vice president of the National Association of Manufacturers, a Washington-based group that represents 11,000 companies such as Exxon Mobil Corp. (XOM) and Southern Co. (SO) The standards, which constitute guidance for agencies and not new regulations, are set to be issued in the coming weeks, according to lawyers briefed by administration officials.

In taking the step, Obama would be fulfilling a vow to act alone in the face of a Republican-run House of Representatives unwilling to pass measures limiting greenhouse gases. He’d expand the scope of a Nixon-era law that was first intended to force agencies to assess the effect of projects on air, water and soil pollution.

“If Congress won’t act soon to protect future generations, I will,” Obama said last month during his State of the Union address. He pledged executive actions “to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.”

Illinois Speech

The president is scheduled to deliver a speech on energy today at the Argonne National Laboratory in Lemont, Illinois. He is pressing Congress to create a $2 billion clean-energy research fund with fees paid by oil and gas producers.

While some U.S. agencies already take climate change into account when assessing projects, the new guidelines would apply across-the-board to all federal reviews. Industry lobbyists say they worry that projects could be tied up in lawsuits or administrative delays.

For example, Ambre Energy Ltd. is seeking a permit from the Army Corps of Engineers to build a coal-export facility at the Port of Morrow in Oregon. Under existing rules, officials weighing approval would consider whether ships in the port would foul the water or generate air pollution locally. The Environmental Protection Agency and activist groups say that review should be broadened to account for the greenhouse gases emitted when exported coal is burned in power plants in Asia.

Keystone Pipeline

Similar analyses could be made for the oil sands that would be transported in TransCanada Corp. (TRP)’s Keystone XL pipeline, and leases to drill for oil, gas and coal on federal lands, such as those for Arch Coal Inc. (ACI) and Peabody Energy Corp. (BTU)

If the new White House guidance is structured correctly, it will require just those kinds of lifecycle reviews, said Bill Snape, senior counsel at the Center for Biological Diversity inWashington. The environmental group has sued to press for this approach, and Snape says lawsuits along this line are certain if the administration approves the Keystone pipeline, which would transport oil from Canada’s tar sands to the U.S. Gulf Coast.

“The real danger is the delays,” said Eisenberg of the manufacturers’ group. “I don’t think the answer is ever going to be ‘no,’ but it can confound things.”

Lawyers and lobbyists are now waiting for the White House’s Council on Environmental Qualityto issue the long bottled-up standards for how agencies should address climate change under the National Environmental Policy Act, signed into law by President Richard Nixon in 1970.

Environmental Impact

NEPA requires federal agencies to consider and publish the environmental impact of their actions before making decisions. Those reviews don’t mandate a specific course of action. They do provide a chance for citizens and environmentalists to weigh in before regulators decide on an action — and to challenge those reviews in court if it’s cleared.

“Each agency currently differs in how their NEPA reviews consider the climate change impacts of projects, as well as how climate change impacts such as extreme weather will affect projects,” Taryn Tuss, a Council on Environmental Quality spokeswoman, said in an e-mail. “CEQ is working to incorporate the public input we received on the draft guidance, and will release updated guidance when it is completed.”

‘Major Shakeup’

The new standards will be “a major shakeup in how agencies conduct NEPA” reviews, said Brendan Cummings, senior counsel for the Center for Biological Diversity in San Francisco.

The White House is looking at requiring consideration of both the increase in greenhouse gases and a project’s vulnerability to flooding, drought or other extreme weather that might result from global warming, according to an initial proposal it issued in 2010. Those full reports would be required for projects with 25,000 metric tons of carbon dioxide equivalent emissions or more per year, the equivalent of burning about 100 rail cars of coal.

The initial draft exempted federal land and resource decisions from the guidance, although CEQ said it was assessing how to handle those cases. Federal lands could be included in the final standards.

The White House guidance itself won’t force any projects to be stopped outright. Instead, it’s likely to prompt lawsuits against federal projects on these grounds, and increase the probability that courts will step in and order extensive reviews as part of the “adequate analysis” required in the law, said George Mannina, an attorney at Nossaman LLP in Washington.

Next Administration

“The question is: Where does this analysis take us?” he said. “Adequate analysis may be much broader than the agency and applicant might consider.”

While the Obama administration’s guidance could be easily rescinded by the next administration, the court rulings that stem from these cases will live on as precedents, Mannina said.

Lobbying groups such as the U.S. Chamber of Commerce, American Petroleum Institute and the National Mining Association weighed in with the White House against including climate in NEPA, a law initially aimed at chemical leaks or air pollution.

“Not only will this result in additional delay of the NEPA process, but will result in speculative and inaccurate modeling that will have direct impacts on approval of specific projects,” the National Mining Association in Washington wrote in comments to the White House in 2010.

Leases Challenged

The group represents Arch Coal (ACI) and Peabody, both based in St. Louis. Leases that theDepartment of Interior issued for those companies to mine for coal in Wyoming are facing lawsuits from environmental groups, arguing that the agency didn’t adequately tally up the effect on global warming from burning that coal.

Given Obama’s pledge to address global warming, “this is a massive contradiction,” said Jeremy Nichols, director of climate at WildEarth Guardians in Denver, which filed lawsuits against the leases.

Arch Coal referred questions to the mining group.

Beth Sutton, a Peabody spokeswoman, said in an e-mail, “We believe the current regulatory approach to surface mine permits is appropriate and protects the environment.”

Since CEQ first announced its proposal, more than three dozen federal approvals were challenged on climate grounds, including a highway project in North Carolina, a methane-venting plan for a coal mine in Colorado, and a research facility in California, according to a chart compiled by the Center for Climate Change Law at Columbia University.

Next Target

The next target is TransCanada (TRP)’s application to build the 1,661-mile (2,673-kilometer) Keystone pipeline. The Sierra Club and 350.org drew 35,000 people to Washington last month to urge Obama to reject the pipeline. Meanwhile, the NEPA review by the State Department included an initial analysis of carbon released when the tar sands are refined into gasoline and used in vehicles.

It stopped short, however, of saying the project would result in an increase in greenhouse gas emissions. With or without the pipeline, the oil sands will be mined and used as fuel, the report said. That finding is likely to be disputed in court if the Obama administration clears the project.

“Keystone is ground zero,” said Snape, of the Center for Biological Diversity. “Clearly this will come into play, and it will be litigated.”

Any actions by the administration now on global warming would pick up on a mixed record over the past four years.

Cap-and-Trade

While Obama failed to get Congress to pass cap-and-trade legislation, the EPA reversed course from the previous administration and ruled that carbon-dioxide emissions endanger public health, opening the way for the agency to regulate it.

Using that finding, the agency raised mileage standards for automobiles and proposed rules for new power plants that would essentially outlaw the construction of new coal-fired power plants that don’t have expensive carbon-capture technology.

Environmentalists such as the Natural Resources Defense Council say the most important action next will be the EPA’s rules for existing power plants, the single biggest source of carbon-dioxide emissions. The NEPA standards are separate from those rules, and will affect how the federal government itself is furthering global warming.

“Agencies do a pretty poor job of looking at climate change impacts,” Rebecca Judd, a legislative counsel at the environmental legal group Earthjustice in Washington. “A thorough guidance would help alleviate that.”

Pobre previsão do tempo (Folha de S.Paulo)

Num artigo publicado na Folha em 2010 (http://goo.gl/fLVDJ), João Moreira Salles discutiu a hipervalorização das humanidades no Brasil, em detrimento de disciplinas como matemática, física e engenharia. Um dos efeitos da distorção, acrescento, é a pouca familiaridade –do público, dos intelectuais, da imprensa– com o discurso técnico e científico. E, por consequência, a docilidade com que são aceitas falácias nessas áreas.

Exemplos: propaganda de governo (números para todos os gostos), dietas da moda (pesquisas com todo tipo de metodologia e patrocínio), tratamentos de saúde (custo-benefício muitas vezes discutível) e até planilhas de futebol (nas quais um volante que só dá passes curtos terá índice de acerto maior que um lançador vertical).

De minha parte, resolvi testar um discurso científico bastante presente no cotidiano: o da meteorologia. Durante 28 dias de janeiro último, anotei erros e acertos do “Jornal do Tempo” (http://jornaldotempo.uol.com.br).

Um trabalho leigo, por certo, e consciente de que o serviço em questão não é representativo do setor no país ou no mundo. A home page do “Jornal do Tempo” apresenta dados que são uma média, um resumo –como na previsão da TV– de registros mais detalhados, inclusive em algumas de suas páginas internas.

Ocorre que médias são a face pública da meteorologia, o tal discurso –em tom seguro e cordial– que nos orienta a escolher a roupa de manhã, a levar ou não o guarda-chuva. E aí, assim como alguma lógica basta para perceber furos em trabalhos estatísticos, não é preciso ser expert para afirmar que há muita imprecisão no ramo.

As temperaturas do meu caderninho quase sempre estiveram dentro dos intervalos previstos na véspera (23 em 28 ocorrências). Comparadas à previsão da semana anterior, o índice cai para 17 em 28. Se botarmos lado a lado o intervalo previsto sete dias antes e o previsto no próprio dia, há diferença em 28 de 28.

Já nas condições atmosféricas, cuja conferência é mais difícil –da minha casa em Pinheiros, não tenho como saber se fui traído por uma garoa enquanto dormia ou algo assim–, houve 15 erros em 28.

São coisas aparentemente sem importância: um ou dois graus a mais, sol durante algumas horas num dia “fechado e chuvoso, com poucas trovoadas”. Mas há reparos objetivos senão aos métodos de medição, ao menos à forma como o resultado é exposto.

Assim, cravar uma temperatura única numa cidade como São Paulo, com seus morros e depressões, paraísos verdes e infernos de concreto em 1,5 milhão de quilômetros quadrados, é inexato por princípio. Igualmente a previsão do tempo numa só frase, que contempla tanto o pé d’água rápido e inofensivo quanto o dilúvio e o caos, dependendo da estrutura do bairro onde se está (“sol, alternando com chuva em forma de pancadas isoladas”).

A questão fica mais complexa quando transcende o território do erro, que é humano e aceitável. E da própria meteorologia, aqui citada apenas como sintoma. A autoridade que emana do discurso científico não se limita a influenciar debates acadêmicos sobre química ou astronomia.

Trata-se, também, de um fenômeno das ciências humanas. Seus desdobramentos políticos, econômicos e morais na sociedade como um todo não são desprezíveis. Foram teorias racialistas que justificaram a escravidão. Foi uma doutrina de incentivo à competição tecnológica que criou as armas nucleares.

No caso do aquecimento global, a grande bandeira científica de hoje, antes de tudo há um imperativo de bom senso: é mais inteligente viver de forma harmônica com a natureza, com menos emissão de carbono, desmatamento e desperdício consumista. Também imagino que previsões de climatologia sejam mais precisas do que, digamos, as da moça que descreve as condições do Sudeste inteiro em dez segundos no “Jornal Nacional”. Mas é fato que a revista “Time” alertou sobre a “nova era glacial” em 1974. E deu uma capa célebre, dez anos depois, sobre a hoje contestada ligação entre infarto e gema de ovo.

Os dois textos reproduziam uma conjectura científica influente à época. É recomendável seguir as que o são hoje –afinal, é o que mais próximo temos de certezas fora do fanatismo religioso ou ideológico. Apenas é bom, como dúvida saudável, em qualquer área de conhecimento vendido como infalível, lembrar da pobre previsão do tempo.

When It Rains These Days, Does It Pour? Has the Weather Become Stormier as the Climate Warms? (Science Daily)

Mar. 17, 2013 — There’s little doubt — among scientists at any rate — that the climate has warmed since people began to release massive amounts greenhouse gases to the atmosphere during the Industrial Revolution.

But ask a scientist if the weather is getting stormier as the climate warms and you’re likely to get a careful response that won’t make for a good quote.

There’s a reason for that.

“Although many people have speculated that the weather will get stormier as the climate warms, nobody has done the quantitative analysis needed to show this is indeed happening,” says Jonathan Katz, PhD, professor of physics at Washington University in St. Louis.

In the March 17 online version ofNature Climate Change, Katz and Thomas Muschinksi, a senior in physics who came to Katz looking for an undergraduate thesis project, describe the results of their analysis of more than 70 years of hourly precipitation data from 13 U.S. sites looking for quantitative evidence of increased storminess.

They found a significant, steady increase in storminess on the Olympic Peninsula in Washington State, which famously suffers from more or less continuous drizzle, a calm climate that lets storm peaks emerge clearly.

“Other sites have always been stormy,” Katz says, “so an increase such as we saw in the Olympic Peninsula data would not have been detectable in their data.”

They may also be getting stormier, he says, but so far they’re doing it under cover.

The difference between wetter and stormier

“We didn’t want to know whether the rainfall had increased or decreased,” Katz says, “but rather whether it was concentrated in violent storm events.”

Studies that look at the largest one-day or few-day precipitation totals recorded in a year, or the number of days in which in which total precipitation is above a threshold, measure whether locations are getting wetter, not whether they’re getting stormier, says Katz.

To get the statistical power to pick up brief downpours rather than total precipitation, Muschinski and Katz needed to find a large, fine-grained dataset.

“So we poked around,” Katz says, “and we found what we were looking for in the National Oceanic and Atmospheric Administration databases.”

NOAA has hourly precipitation data going back to 1940 or even further for many locations in the United States. Muschniski and Katz chose 13 sites that had long runs of data and represented a broad range of climates, from desert to rain forest.

They then tested the hypothesis that storms are becoming more frequent and intense by taking different measurements of the “shape” formed by the data points for each site.

Measuring these “moments” as they’re called, is a statistical test commonly used in science, says Katz, but one that hasn’t been applied to this problem before.

“We found a significant steady increase in stormy activity on the Olympic Peninsula,” Katz says. “We know that is real.”

“We found no evidence for an increase in storminess at the other 12 sites,” he said, “but because their weather is intrinsically stormier, it would be more difficult to detect a trend like that at the Olympic Peninsula even if it were occurring.”

The next step, Katz says, is to look at a much large number of sites that might be regionally averaged to reveal trends too slow to be significant for one site.

“There are larger databases,” he says, “but they’re also harder to sift through. Any one site might have half a million hourly measurements over the period we’re looking at, and to get good results. we have to devise an algorithm tuned to the database to filter out spurious or corrupted data.”

You could call that a rainy-day project.

Bombshell: Recent Warming Is ‘Amazing And Atypical’ And Poised To Destroy Stable Climate That Enabled Civilization (Climate Progress)

By Joe Romm on Mar 8, 2013 at 12:44 pm

New Science Study Confirms ‘Hockey Stick’: The Rate Of Warming Since 1900 Is 50 Times Greater Than The Rate Of Cooling In Previous 5000 Years

Temperature change over past 11,300 years (in blue, via Science, 2013plus projected warming this century on humanity’s current emissions path (in red, via recent literature).

A stable climate enabled the development of modern civilization, global agriculture, and a world that could sustain a vast population. Now, the most comprehensive “Reconstruction of Regional and Global Temperature for the Past 11,300 Years” ever done reveals just how stable the climate has been — and just how destabilizing manmade carbon pollution has been and will continue to be unless we dramatically reverse emissions trends.

Researchers at Oregon State University (OSU) and Harvard University published their findings today in the journal Science. Their funder, the National Science Foundation, explains in a news release:

With data from 73 ice and sediment core monitoring sites around the world, scientists have reconstructed Earth’s temperature history back to the end of the last Ice Age.

The analysis reveals that the planet today is warmer than it’s been during 70 to 80 percent of the last 11,300 years.

… during the last 5,000 years, the Earth on average cooled about 1.3 degrees Fahrenheit–until the last 100 years, when it warmed about 1.3 degrees F.

In short, thanks primarily to carbon pollution, the temperature is changing 50 times faster than it did during the time modern civilization and agriculture developed, a time when humans figured out where the climate conditions — and rivers and sea levels — were most suited for living and farming. We are headed for 7 to 11°F warming this century on our current emissions path — increasing the rate of change 5-fold yet again.

By the second half of this century we will have some 9 billion people, a large fraction of whom will be living in places that simply can’t sustain them —  either because it is too hot and/or dry, the land is no longer arable, their glacially fed rivers have dried up, or the seas have risen too much.

We could keep that warming close to 4°F — and avoid the worst consequences — but only with immediate action.

This research vindicates the work of Michael Mann and others showing that recent warming is unprecedented in magnitude, speed, and cause during the past 2000 years — the so-called Hockey Stick — and in fact extends that back to at least 4000 years ago. I should say “vindicates for the umpteenth time” (see “Yet More Studies Back Hockey Stick“).

Lead author Shaun Marcott of OSU told NPR that the paleoclimate data reveal just how unprecedented our current warming is: “It’s really the rates of change here that’s amazing and atypical.” He noted to the AP, “Even in the ice age the global temperature never changed this quickly.”

And the rate of warming is what matters most, as Mann noted in an email to me:

This is an important paper. The key take home conclusion is that the rate and magnitude of recent global warmth appears unprecedented for *at least* the past 4K and the rate *at least* the past 11K. We know that there were periods in the past that were warmer than today, for example the early Cretaceous period 100 million yr ago. The real issue, from a climate change impacts point of view, is the rate of change—because that’s what challenges our adaptive capacity. And this paper suggests that the current rate has no precedent as far back as we can go w/ any confidence—11 kyr arguably, based on this study.

Katharine Hayhoe, an atmospheric scientist at Texas Tech University, told the AP:

We have, through human emissions of carbon dioxide and other heat-trapping gases, indefinitely delayed the onset of the next ice age and are now heading into an unknown future where humans control the thermostat of the planet.

Unfortunately, we have decided to change the setting on the thermostat from “Very Stable, Don’t Adjust” to “Hell and High Water.” It is the single most self-destructive act humanity has ever undertaken, but there is still time to aggressively slash emissions and aim for a setting of “Dangerous, But Probably Not Fatal.”

A Scientist’s Misguided Crusade (N.Y.Times)

OP-ED COLUMNIST

By JOE NOCERA

Published: March 4, 2013 

Last Friday, at 3:40 p.m., the State Department released its “Draft Supplemental Environmental Impact Statement” for the highly contentious Keystone XL pipeline, which Canada hopes to build to move its tar sands oil to refineries in the United States. In effect, the statement said there were no environmental impediments that would prevent President Obama from approving the pipeline.

Two hours and 20 minutes later, I received a blast e-mail containing a statement by James Hansen, the head of the Goddard Institute for Space Studies at NASA — i.e., NASA’s chief climate scientist. “Keystone XL, if the public were to allow our well-oiled government to shepherd it into existence, would be the first step down the wrong road, perpetuating our addiction to dirty fossil fuels, moving to ever dirtier ones,” it began. After claiming that the carbon in the tar sands “exceeds that in all oil burned in human history,” Hansen’s statement concluded: “The public must demand that the government begin serving the public’s interest, not the fossil fuel industry’s interest.”

As a private citizen, Hansen, 71, has the same First Amendment rights as everyone else. He can publicly oppose the Keystone XL pipeline if he so chooses, just as he can be as politically active as he wants to be in the anti-Keystone movement, and even be arrested during protests, something he managed to do recently in front of the White House.

But the blast e-mail didn’t come from James Hansen, private citizen. It specifically identified Hansen as the head of the Goddard Institute, and went on to describe him as someone who “has drawn attention to the danger of passing climate tipping points, producing irreversible climate impacts that would yield a different planet from the one on which civilization developed.” All of which made me wonder whether such apocalyptic pronouncements were the sort of statements a government scientist should be making — and whether they were really helping the cause of reversing climate change.

Let’s acknowledge right here that the morphing of scientists into activists is nothing new. Linus Pauling, the great chemist, was a peace activist who pushed hard for a nuclear test ban treaty. Albert Einstein also became a public opponent of nuclear weapons.

It is also important to acknowledge that Hansen has been a crucial figure in developing modern climate science. In 2009, Eileen Claussen, now the president of the Center for Climate and Energy Solutions, told The New Yorker that Hansen was a “heroic” scientist who “faced all kinds of pressures politically.” Today, his body of work is one of the foundations upon which much climate science is built.

Yet what people hear from Hansen today is not so much his science but his broad, unscientific views on, say, the evils of oil companies. In 2008, he wrote a paper, the thesis of which was that runaway climate change would occur when carbon in the atmosphere reached 350 parts per million — a point it had already exceeded — unless it were quickly reduced. There are many climate change experts who disagree with this judgment — who believe that the 350 number is arbitrary and even meaningless. Yet an entire movement,350.org, has been built around Hansen’s line in the sand.

Meanwhile, he has a department to run. For a midlevel scientist at the Goddard Institute, what signal is Hansen sending when he takes the day off to get arrested at the White House? Do his colleagues feel unfettered in their own work? There is, in fact, enormous resentment toward Hansen inside NASA, where many officials feel that their solid, analytical work on climate science is being lost in what many of them describe as “the Hansen sideshow.” His activism is not really doing any favors for the science his own subordinates are producing.

Finally, and most important, Hansen has placed all his credibility on one battle: the fight to persuade President Obama to block the Keystone XL pipeline. It is the wrong place for him to make a stand. Even in the unlikely event the pipeline is stopped, the tar sands oil will still be extracted and shipped. It might be harder to do without a pipeline, but it is already happening. And in the grand scheme, as I’ve written before, the tar sands oil is not a game changer. The oil we import from Venezuela today is dirtier than that from the tar sands. Not that the anti-pipeline activists seem to care.

What is particularly depressing is that Hansen has some genuinely important ideas, starting with placing a graduated carbon tax on fossil fuels. Such a tax would undoubtedly do far more to reduce carbon emissions and save the planet than stopping the Keystone XL pipeline.

A carbon tax might be worth getting arrested over. But by allowing himself to be distracted by Keystone, Hansen is hurting the very cause he claims to care so much about.
