3289. Naomi Oreskes, Why Science Failed to Stop Climate Change

By Naomi Oreskes, TomDispatch.com, November 10, 2019
[Note from TomDispatch: Today’s author, Naomi Oreskes, who's done yeoman’s work on climate change issues over the years, has a new book, Why Trust Science? Here are two recommendations for it from figures I admire: Naomi Klein says, “How do we get to the truth? How do we safeguard scientific knowledge (and ourselves) from those whose interests are threatened by it? With her trailblazing work on climate denial and much else, Naomi Oreskes offers an essential perspective on these questions. She tackles them head-on in this clear, utterly compelling book.” Elizabeth Kolbert (author of The Sixth Extinction) agrees, saying the book “should be read by progressives, conservatives, and everyone in between. It’s an important, timely, and utterly compelling book.” Tom]
I saw the piece in the Guardian in July 2018 and must admit I was stunned by it. It wasn’t that, on the issue of climate change, I hadn’t already read plenty of bad news about what was to come for humanity. Somehow, though, this story got to me -- maybe because, once upon a time in another universe, I was a China-scholar-to-be. The headline read: “Unsurvivable heatwaves could strike the heart of China by end of the century.” As a result, the Guardian reported, parts of the heavily populated North China plain -- populated by 400 million people today -- could become “uninhabitable” by 2100 or even earlier.
I mean, tell me that isn’t shocking. Or to jump to the present, what about the recent study that recalibrated what sea-level rise would mean for coastal communities and found, according to the New York Times, that “some 150 million people are now living on land that will be below the high-tide line by midcentury.” That's just 30 years from now!  Look at the accompanying maps in that piece and, as you’ll see, southern Vietnam “could all but disappear.” Talk about “uninhabitable.” The same obviously applies, for example, to parts of Florida (where the president is now moving his residence to escape taxes). That state, after all, has five of the 20 urban areas in this country expected to suffer the most from rising sea levels: Miami, Miami Beach, Panama City, St. Petersburg, and Tampa.
Back in 2013, I coined the term "terrarists" to describe the men who run what may be the most profitable corporations on the planet, giant energy companies like ExxonMobil, Chevron, and Shell,  and to capture what they were doing to the rest of us. Today, Naomi Oreskes, author of the new book Why Trust Science?, offers a genuinely shocking account of how those companies invested significant sums from the money they made broiling this planet and much effort into the promotion of misinformation and disinformation about the harm fossil fuels are doing -- and how effective they’ve been at it. Just look at the Republican Party, once considered the party of the environment and now a party of pyromaniacs. It’s truly a tale from hell, one that threatens the wellbeing of all our children and grandchildren. Tom
The Greatest Scam in History
How the Energy Companies Took Us All
By Naomi Oreskes
It’s a tale for all time. What might be the greatest scam in history or, at least, the one that threatens to take history down with it. Think of it as the climate-change scam that beat science, big time.
Scientists have been seriously investigating the subject of human-made climate change since the late 1950s and political leaders have been discussing it for nearly as long. In 1961, Alvin Weinberg, the director of the Oak Ridge National Laboratory, called carbon dioxide one of the “big problems” of the world “on whose solution the entire future of the human race depends.” Fast-forward nearly 30 years and, in 1992, President George H.W. Bush signed the U.N. Framework Convention on Climate Change (UNFCCC), promising “concrete action to protect the planet.”
Today, with Puerto Rico still recovering from Hurricane Maria and fires burning across California, we know that did not happen. Despite hundreds of scientific reports and assessments, tens of thousands of peer-reviewed scientific papers, and countless conferences on the issue, man-made climate change is now a living crisis on this planet. Universities, foundations, churches, and individuals have indeed divested from fossil fuel companies and, led by a 16-year-old Swedish girl, citizens across the globe have taken to the streets to express their outrage. Children have refused to go to school on Fridays to protest the potential loss of their future. And if you need a measure of how long some of us have been at this, in December, the Conference of Parties to the UNFCCC will meet for the 25th time.
Scientists working on the issue have often told me that, once upon a time, they assumed, if they did their jobs, politicians would act upon the information. That, of course, hasn’t happened. Anything but, across much of the planet. Worse yet, science failed to have the necessary impact in significant part because of disinformation promoted by the major fossil-fuel companies, which have succeeded in diverting attention from climate change and successfully blocking meaningful action.

Making Climate Change Go Away
Much focus has been put on ExxonMobil’s history of disseminating disinformation, partly because of the documented discrepancies between what that company said in public about climate change and what its officials said (and funded) in private. Recently, a trial began in New York City accusing the company of misleading its investors, while Massachusetts is prosecuting ExxonMobil for misleading consumers as well.
If only it had just been that one company, but for more than 30 years, the fossil-fuel industry and its allies have denied the truth about anthropogenic global warming. They have systematically misled the American people and so purposely contributed to endless delays in dealing with the issue by, among other things, discounting and disparaging climate science, mispresenting scientific findings, and attempting to discredit climate scientists. These activities are documented in great detail in How Americans Were Deliberately Misled about Climate Change, a report I recently co-authoredas well as in my 2010 book and 2014 filmMerchants of Doubt.
A key aspect of the fossil-fuel industry’s disinformation campaign was the mobilization of “third-party allies”: organizations and groups with which it would collaborate and that, in some cases, it would be responsible for creating.
In the 1990s, these allied outfits included the Global Climate Coalition, the Cooler Heads Coalition, Informed Citizens for the Environment, and the Greening Earth Society. Like ExxonMobil, such groups endlessly promoted a public message of denial and doubt: that we weren’t really sure if climate change was happening; that the science wasn’t settled; that humanity could, in any case, readily adapt at a later date to any changes that did occur; and that addressing climate change directly would wreck the American economy. Two of these groups -- Informed Citizens for the Environment and the Greening Earth Society -- were, in fact, AstroTurf organizations, created and funded by a coal industry trade association but dressed up to look like grass-roots citizens’ action organizations.
Similar messaging was pursued by a network of think tanks promoting free market solutions to social problems, many with ties to the fossil-fuel industry. These included the George C. Marshall Institute, the Cato Institute, the Competitive Enterprise Institute, the American Enterprise Institute, and the Heartland Institute. Often their politically motivated contrarian claims were presented in formats that make them look like the scientific reports whose findings they were contradicting.
In 2009, for instance, the Cato Institute issued a report that precisely mimicked the format, layout, and structure of the government’s U.S. National Climate Assessment. Of course, it made claims thoroughly at odds with the actual report’s science. The industry also promoted disinformation through its trade associations, including the American Legislative Exchange Council, the American Petroleum Institute, the U.S. Chamber of Commerce, the National Black Chamber of Commerce, and the National Association of Manufacturers.
Both think tanks and trade organizations have been involved in personal attacks on the reputations of scientists. One of the earliest documented was on climate scientist Benjamin Santer at the Lawrence Livermore National Laboratory who showed that the observed increase in global temperatures could not be attributed to increased solar radiation. He served as the lead author of the Second Assessment Report of the U.N.’s prestigious Intergovernmental Panel on Climate Change, or IPCC, responsible for the 1995 conclusion that “the balance of evidence suggests a discernible human impact on the climate system.” Santer became the target of a vicious, arguably defamatory attack by physicists from the George C. Marshall Institute and the Global Climate Coalition, who accused him of fraud. Other climate scientists, including Michael Mann, Jonathan Overpeck, Malcolm Hughes, Ray Bradley, Katharine Hayhoe, Kevin Trenberth, and, I should note, myself, have been subject to harassment, investigation, hacked emails, and politically motivated freedom-of-information attacks.
How to Play Climate Change for a Fool
When it came to industry disinformation, the role of third-party allies was on full display at the House Committee on Oversight hearings on climate change in late October. As their sole witness, the Republicans on that committee invited Mandy Gunasekera, the founder and president of Energy45, a group whose purpose, in its own words, is to “support the Trump energy agenda.”
Energy45 is part of a group known, bluntly enough, as the CO2 Coalition and is a perfect example of what I’ve long thought of as zombie denialism in which older players spouting industry arguments suddenly reappear in new forms. In this case, in the 1990s and early 2000s, the George C. Marshall Institute was a leader in climate-change disinformation. From 1974-1999, its director, William O’Keefe, had also been the executive vice president and later CEO of the American Petroleum Institute. The Marshall Institute itself closed in 2015, only to re-emerge a few years later as the CO2 Coalition.
The comments of Republican committee members offer a sense of just how deeply the climate-change disinformation campaign is now lodged in the heart of the Trump administration and congressional Republicans as 2019 draws to an end and the planet visibly heats. Consider just six of their “facts”:
1) The misleading claim that climate change will be “mild and manageable.” There is no scientific evidence to support this. On the contrary, literally hundreds of scientific reports over the past few decades, including those U.S. National Climate Assessments, have affirmed that any warming above 2 degrees Centigrade will lead to grave and perhaps catastrophic effects on “health, livelihoods, food security, water supply, human security, and economic growth.” The U.N.’s IPCC has recently noted that avoiding the worst impacts of global warming will “require rapid and far-reaching transitions in energy... infrastructure... and industrial systems.”
Recent events surrounding Hurricanes Sandy, Michael, Harvey, Maria, and Dorian, as well as the devastating wildfire at the ironically named town of Paradise, California, in 2018 and the fires across much of that state this fall, have shown that the impacts of climate change are already part of our lives and becoming unmanageable. Or if you want another sign of where this country is at this moment, consider a new report from the Army War College indicating that “the Department of Defense (DoD) is precariously unprepared for the national security implications of climate change-induced global security challenges.” And if the Pentagon isn’t prepared to manage climate change, it’s hard to imagine any part of the U.S. government that might be.
2) The misleading claim that global prosperity is actually being driven by fossil fuels. No one denies that fossil fuels drove the Industrial Revolution and, in doing so, contributed substantively to rising living standards for hundreds of millions of people in Europe, North America, and parts of Asia. But the claim that fossil fuels are the essence of global prosperity today is, at best, a half-truth because what is at stake here isn’t the past but the future. Disruptive climate change fueled by greenhouse gas emissions from the use of oil, coal, and natural gas now threatens both the prosperity that parts of this planet have already achieved and future economic growth of just about any sort. Nicholas Stern, the former chief economist of the World Bank and one of the foremost experts on the economics of climate change, has put our situation succinctly this way: “High carbon growth self-destructs.”
3) A misleading claim that fossil fuels represent “cheap energy.” Fossil fuels are not cheap. When their external costs are included -- that is, not just the price of extracting, distributing, and profiting from them, but what it will cost in all our lives once you add in the fires, extreme storms, flooding, health effects, and everything else that their carbon emissions into the atmosphere will bring about -- they couldn’t be more expensive. The International Monetary Fund estimates that the cost to consumers above and beyond what we pay at the pump or in our electricity bills already comes to more than $5 trillion dollars annually. That’s trillion, not billion. Put another way, we are all paying a massive, largely unnoticed subsidy to the oil, gas, and coal industry to destroy our civilization. Among other things, those subsidies already “damage the environment, caus[e]... premature deaths through local air pollution, [and] exacerbat[e] congestion and other adverse side effects of vehicle use.”
4) A misleading claim about poverty and fossil fuels. That fossil fuels are the solution to the energy needs of the world’s poor is a tale being heavily promoted by ExxonMobil, among others. The idea that ExxonMobil is suddenly concerned about the plight of the global poor is, of course, laughable or its executives wouldn’t be planning (as they are) for significant increases in fossil-fuel production between now and 2030, while downplaying the threat of climate change. As Pope Francis, global justice leader Mary Robinson, and former U.N. Secretary General Ban Ki-Moon -- as well as countless scientists and advocates of poverty reduction and global justice -- have repeatedly emphasized, climate change will, above all, hurt the poor. It is they who will first be uprooted from their homes (and homelands); it is they who will be migrating into an increasingly hostile and walled-in world; it is they who will truly feel the heat, literal and figurative, of it all. A fossil-fuel company that cared about the poor would obviously not be committed, above all else, to pursuing a business model based on oil and gas exploration and development. The cynicism of this argument is truly astonishing.
Moreover, while it’s true that the poor need affordable energy, it is not true that they need fossil fuelsMore than a billion people worldwide lack access (or, at least, reliable access) to electricity, but many of them also lack access to an electricity grid, which means fossil fuels are of little use to them. For such communities, solar and wind power are the only reasonable ways to go, the only ones that could rapidly and affordably be put in place and made available.
5) Misleading assertions about the costs of renewable energy. The cheap fossil fuel narrative is regularly coupled with misleading assertions about the allegedly high costs of renewable energy. According to Bloomberg News, however, in two-thirds of the world, solar is already the cheapest form of newly installed electricity generation, cheaper than nuclear, natural gas, or coal. Improvements in energy storage are needed to maximize the penetration of renewables, particularly in developed countries, but such improvements are happening quickly. Between 2010 and 2017, the price of battery storage decreased a startling 79% and most experts believe that, in the near future, many of the storage problems can and will be solved.
6) The false claim that, under President Trump, the U.S. has actually cut greenhouse gas emissions. Republicans have claimed not only that such emissions have fallen but that the United States under President Trump has done more to reduce emissions than any other country on the planet. One environmental reporter, who has described herself as “accustomed to hearing a lot of misinformation” about climate change, characterized this statement as “brazenly false.” In fact, U.S. CO2 emissions spiked in 2018, increasing by 3.1% over 2017. Methane emissions are also on the rise and President Trump’s proposal to rollback methane standards will ensure that unhappy trend continues.
Science Isn’t Enough
And by the way, when it comes to the oil companies, that’s just to start down a far longer list of misinformation and false claims they’ve been peddling for years. In our 2010 book, Merchants of Doubt, Erik Conway and I showed that the strategies and tactics used by Big Energy to deny the harm of fossil-fuel use were, in many cases, remarkably similar to those long used by the tobacco industry to deny the harm of tobacco use -- and this was no coincidence. Many of the same PR firms, advertising agencies, and institutions were involved in both cases.
The tobacco industry was finally prosecuted by the Department of Justice, in part because of the ways in which the individual companies coordinated with each other and with third-party allies to present false information to consumers. Through congressional hearings and legal discovery, the industry was pegged with a wide range of activities it funded to mislead the American people. Something similar has occurred with Big Energy and the harm fossil fuels are doing to our lives, our civilization, our planet.
Still, a crucial question about the fossil-fuel industry remains to be fully explored: Which of its companies have funded the activities of the trade organizations and other third-party allies who deny the facts about climate change? In some cases, we already know the answers. In 2006, for instance, the Royal Society of the United Kingdom documented ExxonMobil’s funding of 39 organizations that promoted “inaccurate and misleading” views of climate science. The Society was able to identify $2.9 million spent to that end by that company in the year 2005 alone. That, of course, was just one year and clearly anything but the whole story.
Nearly all of these third-party allies are incorporated as 501(c)(3) institutions, which means they must be non-profit and nonpartisan. Often they claim to be involved in education (though mis-education would be the more accurate term). But they are clearly also involved in supporting an industry -- Big Energy -- that couldn’t be more for-profit and they have done many things to support what could only be called a partisan political agenda as well. After all, by its own admission, Energy45, to take just one example, exists to support the “Trump Energy Agenda.”
I’m an educator, not a lawyer, but as one I can say with confidence that the activities of these organizations are the opposite of educational. Typically, the Heartland Institute, for instance, has explicitly targeted schoolteachers with disinformation. In 2017, the institute sent a booklet to more than 200,000 of them, repeating the oft-cited contrarian claims that climate science is still a highly unsettled subject and that, even if climate change were occurring, it “would probably not be harmful.” Of this booklet, the director of the National Center for Science Education said, “It’s not science, but it’s dressed up to look like science. It’s clearly intended to confuse teachers.” The National Science Teaching Association has called it “propaganda” and advised teachers to place their copies in the recycling bin.
Yet, as much as we know about the activities of Heartland and other third-party allies of the fossil-fuel industry, because of loopholes in our laws we still lack basic information about who has funded and sustained them. Much of the funding at the moment still qualifies as “dark money.” Isn’t it time for citizens to demand that Congress investigate this network, as it and the Department of Justice once investigated the tobacco industry and its networks?
ExxonMobil loves to accuse me of being “an activist.” I am, in fact, a teacher and a scholar. Most of the time, I’d rather be home working on my next book, but that increasingly seems like less of an option when Big Energy’s climate-change scam is ongoing and our civilization is, quite literally, at stake. When citizens are inactive, democracy fails -- and this time, if democracy fails, as burning California shows, so much else could fail as well. Science isn’t enough. The rest of us are needed. And we are needed now.

3288. How Scientists Got Climate Change So Wrong


By Eugene Linden, The New York Times, November 8, 2019
Credit...Hiroko Masuike/The New York Times
For decades, most scientists saw climate change as a distant prospect. We now know that thinking was wrong. This summer, for instance, a heatwave in Europe penetrated the Arctic, pushing temperatures into the 80s across much of the Far North and, according to the Belgian climate scientist Xavier Fettweis, melting some 40 billion tons of Greenland’s ice sheet.

Had a scientist in the early 1990s suggested that within 25 years a single heatwave would measurably raise sea levels, at an estimated two one-hundredths of an inch, bake the Arctic and produce Sahara-like temperatures in Paris and Berlin, the prediction would have been dismissed as alarmist. But many worst-case scenarios from that time are now realities.

Science is a process of discovery. It can move slowly as the pieces of a puzzle fall together and scientists refine their investigative tools. But in the case of climate, this deliberation has been accompanied by inertia born of bureaucratic caution and politics. A recent essay in Scientific American argued that scientists “tend to underestimate the severity of threats and the rapidity with which they might unfold” and said one of the reasons was “the perceived need for consensus.” This has had severe consequences, diluting what should have been a sense of urgency and vastly understating the looming costs of adaptation and dislocation as the planet continues to warm.

In 1990, the Intergovernmental Panel on Climate Change, the United Nations group of thousands of scientists representing 195 countries, said in its first report that climate change would arrive at a stately pace, that the methane-laden Arctic permafrost was not in danger of thawing, and that the Antarctic ice sheets were stable.

Relying on the climate change panel’s assessment, economists estimated that the economic hit would be small, providing further ammunition against an aggressive approach to reducing emissions and to building resilience to climate change.

As we now know, all of those predictions turned out to be completely wrong. Which makes you wonder whether the projected risks of further warming, dire as they are, might still be understated. How bad will things get?

So far, the costs of underestimation have been enormous. New York City’s subway system did not flood in its first 108 years, but Hurricane Sandy’s 2012 storm surge caused nearly $5 billion in water damage, much of which is still not repaired. In 2017, Hurricane Harvey gave Houston and the surrounding region a $125 billion lesson about the costs of misjudging the potential for floods.

The climate change panel seems finally to have caught up with the gravity of the climate crisis. Last year, the organization detailed the extraordinary difficulty of limiting warming to 2.7 degrees Fahrenheit (1.5 degrees Celsius), over the next 80 years, and the grim consequences that will result even if that goal is met.More likely, a separate United Nations report concluded, we are headed for warming of at least 5.4 degrees Fahrenheit. That will come with almost unimaginable damage to economies and ecosystems. Unfortunately, this dose of reality arrives more than 30 years after human-caused climate change became a mainstream issue.

The word “upended” does not do justice to the revolution in climate science wrought by the discovery of sudden climate change. The realization that the global climate can swing between warm and cold periods in a matter of decades or even less came as a profound shock to scientists who thought those shifts took hundreds if not thousands of years.

Scientists knew major volcanic eruptions or asteroid strikes could affect climate rapidly, but such occurrences were uncommon and unpredictable. Absent such rare events, changes in climate looked steady and smooth, a consequence of slow-moving geophysical factors like the earth’s orbital cycle in combination with the tilt of the planet’s axis, or shifts in the continental plates.

Then, in the 1960s, a few scientists began to focus on an unusual event that took place after the last ice age. Scattered evidence suggested that the post-ice age warming was interrupted by a sudden cooling that began around 12,000 years ago and ended abruptly 1,300 years later. The era was named the Younger Dryas for a plant that proliferated during that cold period.

At first, some scientists questioned the rapidity and global reach of the cooling. A report from the National Academies of Science in 1975 acknowledged the Younger Dryas but concluded that it would take centuries for the climate to change in a meaningful way. But not everyone agreed. The climate scientist Wallace Broecker at Columbia had offered a theory that changes in ocean circulation could bring about sudden climate shifts like the Younger Dryas.

And it was Dr. Broecker who, in 1975, the same year as that National Academies report playing down the Younger Dryas, published a paper, titled “Climatic Change: Are We on the Brink of a Pronounced Global Warming?” in which he predicted that emissions of carbon dioxide would raise global temperatures significantly in the 21st century. This is now seen as prophetic, but at the time, Dr. Broecker was an outlier.

Then, in the early 1990s, scientists completed more precise studies of ice cores extracted from the Greenland ice sheet. Dust and oxygen isotopes encased in the cores provided a detailed climate record going back eons. It revealed that there had been 25 rapid climate change events like the Younger Dryas in the last glacial period.

The evidence in those ice cores would prove pivotal in turning the conventional wisdom. As the science historian Spencer Weart put it: “How abrupt was the discovery of abrupt climate change? Many climate experts would put their finger on one moment: the day they read the 1993 report of the analysis of Greenland ice cores. Before that, almost nobody confidently believed that the climate could change massively within a decade or two; after the report, almost nobody felt sure that it could not.”

In 2002, the National Academies acknowledged the reality of rapid climate change in a report, “Abrupt Climate Change: Inevitable Surprises,” which described the new consensus as a “paradigm shift.” This was a reversal of its 1975 report.

“Large, abrupt climate changes have affected hemispheric to global regions repeatedly, as shown by numerous paleoclimate records,” the report said, and added that “changes of up to 16 degrees Celsius and a factor of 2 in precipitation have occurred in some places in periods as short as decades to years.”

The National Academies report added that the implications of such potential rapid changes had not yet been considered by policymakers and economists. And even today, 17 years later, a substantial portion of the American public remains unaware or unconvinced it is happening.

Were the ice sheets of Greenland and Antarctica to melt, sea levels would rise by an estimated 225 feet worldwide. Few expect that to happen anytime soon. But those ice sheets now look a lot more fragile than they did to the climate change panel in 1995, when it said that little change was expected over the next hundred years.

In the years since data has shown that both Greenland and Antarctica have been shedding ice far more rapidly than anticipated. Ice shelves, which are floating extensions of land ice, hold back glaciers from sliding into the sea and eventually melting. In the early 2000s, ice shelves began disintegrating in several parts of Antarctica, and scientists realized that process could greatly accelerate the demise of the vastly larger ice sheets themselves. And some major glaciers are dumping ice directly into the ocean.

By 2014, a number of scientists had concluded that an irreversible collapse of the West Antarctic ice sheet had already begun, and computer modeling in 2016 indicated that its disintegration in concert with other melting could raise sea levels up to six feet by 2100, about twice the increase described as a possible worst-case scenario just three years earlier. At that pace, some of the world’s great coastal cities, including New York, London and Hong Kong, would become inundated.

Then this year, a review of 40 years of satellite images suggested that the East Antarctic ice sheet, which was thought to be relatively stable, may also be shedding vast amounts of ice.

As the seas rise, they are also warming at a pace unanticipated as recently as five years ago. This is very bad news. For one thing, a warmer ocean means more powerful storms, and die-offs of marine life, but it also suggests that the planet is more sensitive to increased carbon dioxide emissions than previously thought.

The melting of permafrost has also defied expectations. This is ground that has remained frozen for at least two consecutive years and covers around a quarter of the exposed land mass of the Northern Hemisphere. As recently as 1995, it was thought to be stable. But by 2005, the National Center for Atmospheric Research estimated that up to 90 percent of the Northern Hemisphere’s topmost layer of permafrost could thaw by 2100, releasing vast amounts of carbon dioxide and methane into the atmosphere.

For all of the missed predictions, changes in the weather are confirming earlier expectations that a warming globe would be accompanied by an increase in the frequency and severity of extreme weather. And there are new findings unforeseen by early studies, such as the extremely rapid intensification of storms, as on Sept. 1, when Hurricane Dorian’s sustained winds intensified from 150 to 185 miles per hour in just nine hours, and last year when Hurricane Michael grew from tropical depression to major hurricane in just two days.

If the Trump administration has its way, even the revised worst-case scenarios may turn out to be too rosy. In late August, the administration announced a plan to roll back regulations intended to limit methane emissions resulting from oil and gas exploration, despite opposition from some of the largest companies subject to those regulations. More recently, its actions approached the surreal as the Justice Department opened an antitrust investigation into those auto companies that have agreed in principle to abide by higher gas mileage standards required by California. The administration also formally revoked a waiver allowing California to set stricter limits on tailpipe emissions than the federal government.

Even if scientists end up having lowballed their latest assessments of the consequences of the greenhouse gases we continue to emit into the atmosphere, their predictions are dire enough. But the Trump administration has made its posture toward climate change abundantly clear: Bring it on!
It’s already here. And it is going to get worse. A lot worse.

2102. Paris Climate Talks Avoid Scientists’ Idea of ‘Carbon Budget’

By Justin Gillis, The New York Times, November 28, 2015


After two decades of talks that failed to slow the relentless pace of global warming, negotiators from almost 200 countries are widely expected to sign a deal in the next two weeks to take concrete steps to cut emissions.

The prospect of progress, any progress, has elicited cheers in many quarters. The pledges that have already been announced “represent a clear and determined down payment on a new era of climate ambition from the global community of nations,” said Christiana Figueres, executive secretary of the United Nations Framework Convention on Climate Change, in a statement a month ago.

Yet the negotiators gathering in Paris will not be discussing any plan that comes close to meeting their own stated goal of limiting the increase of global temperatures to a reasonably safe level.

They have pointedly declined to take up a recommendation from scientists, made several years ago, that they set a cap on total greenhouse gases as a way to achieve that goal, and then figure out how to allocate the emissions fairly. The pledges countries are making are voluntary, and were established in most nations as a compromise between the desire to be ambitious and the perceived cost and political difficulty of emissions cutbacks.

In effect, the countries are vowing to make changes that collectively still fall far short of the necessary goal, much like a patient who, upon hearing from his doctor that he must lose 50 pounds to avoid life-threatening health risks, takes pride in cutting out fries but not cake and ice cream.

The scientists argue that there is only so much carbon — in the form of exhaust from coal-burning power plants, automobile tailpipes, forest fires and the like — that the atmosphere can absorb before the planet suffers profound damage, with swaths of it potentially becoming uninhabitable.

After years of studying the issue, the experts recommended to climate diplomats in 2013 that they consider the concept of a “carbon budget” to help frame the talks. Yet the idea was quickly dismissed as politically impractical, and more recent pleas from countries like Bolivia to consider it have been ignored.

If any serious push had been made ahead of Paris to divvy up the emissions budget, the negotiators “would have all run screaming from the room,” said Michael A. Levi, an energy expert at the Council on Foreign Relations, in New York. “So that’s not a real alternative.”

The carbon budget will probably not get much attention in Paris for simple reasons.

Wrestling with a budget would, for instance, throw into stark relief the global inequities at the heart of the climate crisis. And it would underscore just how big the problem really is, how costly the delay in tackling it has been and how inadequate the plans being discussed in Paris are for limiting the risks.

Consider, for example, that Europe, the United States and China have offered emissions-reduction pledges that are their most ambitious ever. And yet, if their plans are carried out, a recent analysis suggests those regions will use up most of the remaining room for emissions in the atmosphere, leaving relatively little for the other five billion people on the planet or their descendants.

To change that equation, the biggest polluters would have to commit to cutting their emissions at rates that would be difficult to achieve, potentially disruptive to their economies and politically unrealistic.

Moreover, any serious discussion of the carbon budget would amplify a point of serious contention, known as “climate injustice,” in the talks. It refers to the idea that poor countries bear little past responsibility for climate change but are first in line to suffer its consequences, without much capacity to protect themselves.

Many of those same countries want to develop their economies by burning some fossil fuels, but because decades of high emissions by richer countries have created such profound risks, they are under pressure to adopt costlier green energy instead.

The idea of a carbon budget is based on a goal that the nations of the world set for themselves. In hopes of heading off the worst effects of climate change, they agreed in Cancún in 2010 to try to keep the warming of the planet to no more than 3.6 degrees Fahrenheit, or 2 degrees Celsius, above the level that prevailed before the Industrial Revolution.

Many scientists do not believe that such a limit would be particularly safe — it may still cause the sea to rise 20 feet or more, for instance, over a long period — but they agree that going beyond it would certainly be disastrous, precipitating an even larger rise of the sea, catastrophic heat waves, difficulty producing enough food and many other problems.

A series of scientific papers in 2009 demonstrated that limiting the temperature increase to 3.6 degrees Fahrenheit could be achieved by calculating the total amount of carbon dioxide and other greenhouse gases that could be emitted into the atmosphere before emissions needed to stop. The United Nations committee that periodically reviews climate science, the Intergovernmental Panel on Climate Change, highlighted the idea in a report it issued in Stockholm in 2013.

The group calculated a budget that can be thought of as something like — to use another food metaphor — a carbon pie, with the central question being: How can it be carved up fairly?
The problem is that about two-thirds of the pie has already been eaten by a handful of rich countries, plus China. At current rates, the remainder of it will be gone in 30 years or less. Many poor countries are crowding around the table, pleading for a sliver, but the big emitting countries insist on laying claim to most of the rest of the pie.

It is already clear, based on analyses published recently by several groups, that the pledges to cut emissions will come nowhere close to meeting the carbon budget. Many negotiators are pushing for a mechanism in which countries would gradually ratchet up their commitments to cutting greenhouse gases over time. But that would entail more delays, and it is not certain the carbon limit can be met that way.

Given the political realities, some of the scientists involved in devising the budget have resigned themselves to seeing it ignored in this round of negotiations, with the hope that countries will accelerate their efforts in coming years.

Myles R. Allen, a climate scientist at Oxford University and a leading proponent of the budget idea, said it was better for countries to keep negotiating than not. “It was probably the right call to brush it under the carpet for now,” he said.

Though it will be ignored in Paris, the idea of a carbon budget is gaining currency in the broader world of climate-change politics. For instance, the notion is at the heart of the student-led movement urging college endowment funds and other investors to shed their holdings in fossil-fuel companies. The students’ argument is not just that the companies are blocking needed change, but that they represent risky investments, given that much of the fossil fuels they hold as reserves cannot be burned if the world intends to stay within the carbon budget.

The same idea was at the heart of a speech recently by Mark Carney, the head of the Bank of England, who cited the potential economic risks of “unburnable carbon,” as it has become known. It is even an element of a recently disclosed investigation by the New York attorney general, who is studying whether Exxon Mobil and other companies have properly disclosed to investors the possibility that they may not be able to burn all their reserves.
Yet, within a month of the adoption of the carbon budget, as part of the Stockholm report two years ago, the idea of using it in the global negotiations had been dismissed out of hand. “I don’t think it’s possible,” Ms. Figueres, of the Framework Convention on Climate Change, told The Guardian newspaper that fall.

Some country or group of countries may well try to inject the carbon budget into the Paris talks. But most delegates are so unenthusiastic about the concept that it is likely to be quickly dismissed. Dr. Levi, of the Council on Foreign Relations, is among the realists about what can be achieved in the negotiations.

“The only way you can assess foreign policy is by asking, is what we’re getting better than something else?” Dr. Levi said in an interview. “I don’t see a better deal out there.”
