Summer Is Normal. Heat Season Is Deadly. - The Atlantic - 0 views

  • too few Americans think about heat waves, which claim more lives globally than any other weather-related hazard, as a problem for which systematic, long-term preparation is warranted. To protect human life as temperatures soar, we need to conceive of what we might call heat season as a phenomenon distinct from summer—a part of the year that people in much of the country have traditionally viewed with great fondness.
  • Historically, wildfire season in the United States has begun in May and ended in October; however, wildfires raged well into December last year.
  • The annual Atlantic hurricane season formally begins June 1 and ends November 30. The emergence of Tropical Storm Ana on May 22 made 2021 the seventh consecutive year that a storm strong enough to be named formed off-season.

  • Meanwhile, the economic ramifications of heat waves become clearer every year. In 2017, 120-degree heat grounded flights in Phoenix. In Washington, D.C., and London, train service abruptly halted when tracks melted
  • According to the International Labour Organization, heat stress is also projected to reduce total working hours worldwide by 2.2 percent by 2030—“a productivity loss equivalent to 80 million full-time jobs.”
  • The direct physical threat may be most acute in cities, where temperatures on a scorching summer day can vary by as much as 45 degrees from a well-shaded area to one without trees. This is one more way in which poor Americans bear the brunt of broiling temperatures. As noted by the nonprofit American Forests, a map of tree cover in America’s cities is in many cases a map of income and race.
  • Heat season is upon us. We must acknowledge our risks to manage and survive them, and that process begins by calling the silent killer by its real name.

For Europe's Older Population, Heat Is the New Covid - The New York Times - 0 views

  • But for many seniors, heat has become the new Covid. The searing temperatures have settled over the continent like another indiscriminate plague, reinforcing the isolation of many older people and the threats to their health, and pushing governments and social services to take extraordinary steps to try to protect them.
  • As temperatures rise, the threat to Europe’s elderly is now widespread, with southern European nations being joined by others as far north as Belgium in putting heat plans in place
  • For Italy, the extreme heat has forged a pincer with the country’s most pressing demographic trend — an aging population — to present an especially acute crisis. About 24 percent of Italians are over 65, making it the oldest country in Europe, and over 4 million of them live alone.
  • ...9 more annotations...
  • After 2003, Italy became one of the first countries in Europe to put in place a national plan to mitigate the impact of extreme heat, based on the guidelines from the World Health Organization.
  • “Older people with pre-existing illnesses are more vulnerable,” Andrea Ungar, the president of Italy’s Society of Gerontology and Geriatrics, said in a phone interview. “But poverty and isolation also play a crucial role.”
  • Europe’s hottest summer on record, in 2003, left more than 70,000 people dead, by some estimates, and since then Italy has only grown older. It has struggled to adapt.
  • Almost 30 percent of the 61,000 people estimated to have died last summer from extreme heat in Europe were Italians, with age playing a significant factor. The number of Italians over 80 is now about 4.5 million, almost double the number of 20 years ago.
  • The measures include an alert system to warn people to modify their behavior to safeguard their health
  • Days like Wednesday, when the heat wave peaked, are marked in red on the daily bulletin that Italy’s Health Ministry issues to warn residents. Television channels periodically broadcast the ministry’s guidelines, advising people to stay indoors during the hottest hours; to wear light clothes and sunscreen; to drink lots of water, eat fresh fruits and avoid coffee and alcoholic beverages; and to be particularly careful when going outside.
  • The hottest summer on record killed 15,000 in France, the majority of them older people, living alone in city apartments or retirement homes with no air conditioning
  • Last summer, when successive heat waves hit the country, more than 2,800 French people died, some 80 percent over the age of 75
  • Even those who don’t need medical aid, assistance remains crucial and, for many vulnerable people, associations like Caritas are still the most reliable weekly help. Ms. Antonelli, the social worker, carried two cases of slightly fizzy water up two flights of stairs for Francesca Azzarita, a 91-year-old who lives alone with nothing to cool herself but a piece of cardboard to use as a fan

Climate change is amplifying deadly heatwaves - The Washington Post - 0 views

  • Four hundred deaths in the Netherlands. More than 18,000 hospitalizations in Japan. An estimated 169 million people on alert in the United States
  • This isn’t the plot of a disaster movie. The numbers reflect the impact of extreme heat waves that smothered countries around the world in July and early August, a phenomenon that scientists warn will intensify as the Earth warms.
  • “This is not science fiction. It is the reality of climate change,” he said. “It is happening now, and it will worsen in the future without urgent climate action.”
  • ...7 more annotations...
  • In the Netherlands, 400 more people died in the next-to-last week of July than normally would have during a typical summer week, the country’s statistics agency said Friday
  • On the other side of the planet, a heat wave in Japan stretched from July 29 to Aug. 4 and killed at least 57 people, while more than 18,000 others were taken to hospitals, with 100 in serious condition
  • NHK reported that 45 people in Tokyo had died in a week because of the heat.
  • A 2008 study by the Centers for Disease Control and Prevention found that extreme heat events “are the most prominent cause of weather-related human mortality in the U.S., responsible for more deaths annually than hurricanes, lightning, tornadoes, floods, and earthquakes combined.”
  • Climate change would cause illnesses such as asthma and hay fever to become more severe, while wildfires and pollution also posed a risk to respiratory health. Rising temperatures would alter the geographic distribution of disease-carrying insects and pests, endangering new populations.
  • “Climate change is a public health crisis,” Vijay Limaye told The Post. “The science is really strong in telling us that with climate change accelerating, we expect heat waves to be more frequent, more intense and longer.”
  • “As a nation and as a globe, we are not prepared to confront an ever-mounting heat risk in terms of our health,” he said. For example, while air conditioning was known to save lives, Limaye warned that increased reliance on the technology could have a harmful long-term effect if the energy used for cooling continued to come from fossil fuels.

A Hotter World - The New York Times - 0 views

  • India has contributed little to climate change: Home to 18 percent of the world’s population, it has emitted just 3 percent of planet-warming greenhouse gases.
  • It is happening right now: Over the past three months, a heat wave has devastated North India and neighboring Pakistan. Temperatures surpassed 110 degrees Fahrenheit. It is so hot that overheated birds fell out of the sky in Gurgaon, India, and a historic bridge in northern Pakistan collapsed after melting snow and ice at a glacial lake released a torrent of water.
  • Indians have responded by staying indoors as much as possible, particularly during the afternoon hours. The government has encouraged this, pushing schools to close early and businesses to shift work schedules. The measures have kept down deaths — with fewer than 100 recorded so far, an improvement from heat waves years ago that killed thousands.
  • ...6 more annotations...
  • But these measures have costs. Schooling time is cut short, so students learn less. People do not travel to their jobs, so work is less productive. The heat kept some farmers inside and stunted harvests, so crop yields fell and global food prices increased. Social life is disrupted.
  • The geography of poor countries — many are close to the Equator — is not the only reason climate change is such a burden for them. Their poverty is another factor, leaving them with fewer resources to adapt.
  • “Climate change is one of the most profound inequities of the modern era,”
  • There is a paradox to the climate crisis. Because India never fully industrialized, it has not released as many greenhouse gases as the U.S., European nations and other rich countries. But because it has not industrialized, it also has fewer resources to adapt than the richer, polluting nations.
  • Fewer than 10 percent of Indians have air-conditioning at home.
  • The rush for clean energy technologies, like solar and wind power, is an effort to break that tension — to give countries a way to industrialize without the planet-warming pollution. With climate disasters already hitting much of the world, that effort is in a race against time to prevent more crises like India’s.

France Faces 'Most Severe' Drought as Heat Persists in Europe - The New York Times - 0 views

  • Heat waves in Europe are increasing in frequency and intensity at a faster rate than almost any other part of the planet, according to scientists, who say that global warming and other factors like the circulation of the atmosphere and the ocean all play a role.
  • In Germany, more than 100 firefighters battled flames that engulfed parts of Grunewald, a forest in the west of Berlin, after munitions and fireworks exploded at the city’s bomb disposal site on Thursday morning.
  • The drought has been particularly devastating for European agriculture, which was already suffering from an abnormally dry spring season, parching crops, making it harder to feed livestock and raising worries about reduced harvests.

  • n Germany, the Rhine — the country’s most important water transport route — was so low that some ships have been forced to reduce their cargo loads. Uniper, a German power utility, even announced Thursday that it would reduce output from its largest coal-firing power plants because insufficient coal could be shipped to the plant via the Rhine.
  • And in France, which gets about 70 percent of its electricity from nuclear energy, heat waves have hampered power plants because they use water to cool their reactors. Several have been forced to reduce production over the past month, or to exceed normal temperature limits for the water that they release back into natural waterways.
  • “Because of climate change,” he said, “we are going to have to get used to these kinds of episodes.”

Oceans are warming at the same rate as if five Hiroshima bombs were dropped in every se... - 0 views

  • The world's oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second, scientists have said.
  • "The upward trend is relentless, and so we can say with confidence that most of the warming is man-made climate change," said Kevin Trenberth, distinguished senior scientist in the Climate Analysis Section at the National Center for Atmospheric Research.
  • "There are no reasonable alternatives aside from the human emissions of heat trapping gases to explain this heating," Cheng said, adding that to reach this temperature, the ocean would have taken in 228,000,000,000,000,000,000,000 -- or 228 sextillion -- joules of heat.

  • Oceans serve as a good indicator of the real impact of climate change. Covering almost three quarters of Earth's surface, they absorb the vast majority of the world's heat. Since 1970, more than 90% of the planet's excess heat went into the oceans, while less than 4% was absorbed by the atmosphere and the land, the study said.
  • Rising temperatures also mean ocean waters have less oxygen and are becoming more acidic, which has a major impact on nutrients that feed marine wildlife. For example, when an ocean heat wave struck the waters of Western Australia in 2011, scientists noticed there were fewer dolphin births and the animal's survival rate dropped.
  • "If the leaders of the world changed course, a revolution could take place over about 15 years ... this requires the leaders of China, and the US in particular, along with Europe, to take a strong leadership role and set the stage for the rest of the world to follow," he said.

Losing Earth: The Decade We Almost Stopped Climate Change - The New York Times - 0 views

  • As Malcolm Forbes Baldwin, the acting chairman of the president’s Council for Environmental Quality, told industry executives in 1981, “There can be no more important or conservative concern than the protection of the globe itself.”
  • Among those who called for urgent, immediate and far-reaching climate policy were Senators John Chafee, Robert Stafford and David Durenberger; the E.P.A. administrator, William K. Reilly; and, during his campaign for president, George H.W. Bush.
  • It was understood that action would have to come immediately. At the start of the 1980s, scientists within the federal government predicted that conclusive evidence of warming would appear on the global temperature record by the end of the decade, at which point it would be too late to avoid disaster.

  • If the world had adopted the proposal widely endorsed at the end of the ’80s — a freezing of carbon emissions, with a reduction of 20 percent by 2005 — warming could have been held to less than 1.5 degrees.
  • Action had to be taken, and the United States would need to lead. It didn’t.
  • There can be no understanding of our current and future predicament without understanding why we failed to solve this problem when we had the chance.
  • The first suggestion to Rafe Pomerance that humankind was destroying the conditions necessary for its own survival came on Page 66 of the government publication EPA-600/7-78-019. It was a technical report about coal
  • ‘This Is the Whole Banana’ Spring 1979
  • here was an urgent problem that demanded their attention, MacDonald believed, because human civilization faced an existential crisis. In “How to Wreck the Environment,” a 1968 essay published while he was a science adviser to Lyndon Johnson, MacDonald predicted a near future in which “nuclear weapons were effectively banned and the weapons of mass destruction were those of environmental catastrophe.” One of the most potentially devastating such weapons, he believed, was the gas that we exhaled with every breath: carbon dioxide. By vastly increasing carbon emissions, the world’s most advanced militaries could alter weather patterns and wreak famine, drought and economic collapse.
  • the Jasons. They were like one of those teams of superheroes with complementary powers that join forces in times of galactic crisis. They had been brought together by federal agencies, including the C.I.A, to devise scientific solutions to national-security problems: how to detect an incoming missile; how to predict fallout from a nuclear bomb; how to develop unconventional weapons, like plague-infested rats.
  • Agle pointed to an article about a prominent geophysicist named Gordon MacDonald, who was conducting a study on climate change with the Jasons, the mysterious coterie of elite scientists to which he belonged
  • During the spring of 1977 and the summer of 1978, the Jasons met to determine what would happen once the concentration of carbon dioxide in the atmosphere doubled from pre-Industrial Revolution levels. It was an arbitrary milestone, the doubling, but a useful one, as its inevitability was not in question; the threshold would most likely be breached by 2035.
  • The Jasons’ report to the Department of Energy, “The Long-Term Impact of Atmospheric Carbon Dioxide on Climate,” was written in an understated tone that only enhanced its nightmarish findings: Global temperatures would increase by an average of two to three degrees Celsius; Dust Bowl conditions would “threaten large areas of North America, Asia and Africa”; access to drinking water and agricultural production would fall, triggering mass migration on an unprecedented scale. “Perhaps the most ominous feature,” however, was the effect of a changing climate on the poles. Even a minimal warming “could lead to rapid melting” of the West Antarctic ice sheet. The ice sheet contained enough water to raise the level of the oceans 16 feet.
  • MacDonald explained that he first studied the carbon-dioxide issue when he was about Pomerance’s age — in 1961, when he served as an adviser to John F. Kennedy. Pomerance pieced together that MacDonald, in his youth, had been something of a prodigy: In his 20s, he advised Dwight D. Eisenhower on space exploration; at 32, he became a member of the National Academy of Sciences; at 40, he was appointed to the inaugural Council on Environmental Quality, where he advised Richard Nixon on the environmental dangers of burning coal. He monitored the carbon-dioxide problem the whole time, with increasing alarm.
  • They were surprised to learn how few senior officials were familiar with the Jasons’ findings, let alone understood the ramifications of global warming. At last, having worked their way up the federal hierarchy, the two went to see the president’s top scientist, Frank Press.
  • Thus began the Gordon and Rafe carbon-dioxide roadshow. Beginning in the spring of 1979, Pomerance arranged informal briefings with the E.P.A., the National Security Council, The New York Times, the Council on Environmental Quality and the Energy Department, which, Pomerance learned, had established an Office of Carbon Dioxide Effects two years earlier at MacDonald’s urging
  • . Out of respect for MacDonald, Press had summoned to their meeting what seemed to be the entire senior staff of the president’s Office of Science and Technology Policy — the officials consulted on every critical matter of energy and national security. What Pomerance had expected to be yet another casual briefing assumed the character of a high-level national-security meeting.
  • MacDonald would begin his presentation by going back more than a century to John Tyndall — an Irish physicist who was an early champion of Charles Darwin’s work and died after being accidentally poisoned by his wife. In 1859, Tyndall found that carbon dioxide absorbed heat and that variations in the composition of the atmosphere could create changes in climate. These findings inspired Svante Arrhenius, a Swedish chemist and future Nobel laureate, to deduce in 1896 that the combustion of coal and petroleum could raise global temperatures. This warming would become noticeable in a few centuries, Arrhenius calculated, or sooner if consumption of fossil fuels continued to increase.
  • Four decades later, a British steam engineer named Guy Stewart Callendar discovered that, at the weather stations he observed, the previous five years were the hottest in recorded history. Humankind, he wrote in a paper, had become “able to speed up the processes of Nature.” That was in 1939.
  • MacDonald’s history concluded with Roger Revelle, perhaps the most distinguished of the priestly caste of government scientists who, since the Manhattan Project, advised every president on major policy; he had been a close colleague of MacDonald and Press since they served together under Kennedy. In a 1957 paper written with Hans Suess, Revelle concluded that “human beings are now carrying out a large-scale geophysical experiment of a kind that could not have happened in the past nor be reproduced in the future.” Revelle helped the Weather Bureau establish a continuous measurement of atmospheric carbon dioxide at a site perched near the summit of Mauna Loa on the Big Island of Hawaii, 11,500 feet above the sea — a rare pristine natural laboratory on a planet blanketed by fossil-fuel emissions.
  • After nearly a decade of observation, Revelle had shared his concerns with Lyndon Johnson, who included them in a special message to Congress two weeks after his inauguration. Johnson explained that his generation had “altered the composition of the atmosphere on a global scale” through the burning of fossil fuels, and his administration commissioned a study of the subject by his Science Advisory Committee. Revelle was its chairman, and its 1965 executive report on carbon dioxide warned of the rapid melting of Antarctica, rising seas, increased acidity of fresh waters — changes that would require no less than a coordinated global effort to forestall.Yet emissions continued to rise, and at this rate, MacDonald warned, they could see a snowless New England, the swamping of major coastal cities, as much as a 40 percent decline in national wheat production, the forced migration of about one-quarter of the world’s population. Not within centuries — within their own lifetimes.
  • On May 22, Press wrote a letter to the president of the National Academy of Sciences requesting a full assessment of the carbon-dioxide issue. Jule Charney, the father of modern meteorology, would gather the nation’s top oceanographers, atmospheric scientists and climate modelers to judge whether MacDonald’s alarm was justified — whether the world was, in fact, headed to cataclysm.
  • If Charney’s group confirmed that the world was careering toward an existential crisis, the president would be forced to act.
  • Hansen turned from the moon to Venus. Why, he tried to determine, was its surface so hot? In 1967, a Soviet satellite beamed back the answer: The planet’s atmosphere was mainly carbon dioxide. Though once it may have had habitable temperatures, it was believed to have succumbed to a runaway greenhouse effect: As the sun grew brighter, Venus’s ocean began to evaporate, thickening the atmosphere, which forced yet greater evaporation — a self-perpetuating cycle that finally boiled off the ocean entirely and heated the planet’s surface to more than 800 degrees Fahrenheit
  • At the other extreme, Mars’s thin atmosphere had insufficient carbon dioxide to trap much heat at all, leaving it about 900 degrees colder. Earth lay in the middle, its Goldilocks greenhouse effect just strong enough to support life.
  • We want to learn more about Earth’s climate, Jim told Anniek — and how humanity can influence it. He would use giant new supercomputers to map the planet’s atmosphere. They would create Mirror Worlds: parallel realities that mimicked our own. These digital simulacra, technically called “general circulation models,” combined the mathematical formulas that governed the behavior of the sea, land and sky into a single computer model. Unlike the real world, they could be sped forward to reveal the future.
  • The government officials, many of them scientists themselves, tried to suppress their awe of the legends in their presence: Henry Stommel, the world’s leading oceanographer; his protégé, Carl Wunsch, a Jason; the Manhattan Project alumnus Cecil Leith; the Harvard planetary physicist Richard Goody. These were the men who, in the last three decades, had discovered foundational principles underlying the relationships among sun, atmosphere, land and ocean — which is to say, the climate.
  • When, at Charney’s request, Hansen programmed his model to consider a future of doubled carbon dioxide, it predicted a temperature increase of four degrees Celsius. That was twice as much warming as the prediction made by the most prominent climate modeler, Syukuro Manabe, whose government lab at Princeton was the first to model the greenhouse effect. The difference between the two predictions — between warming of two degrees Celsius and four degrees Celsius — was the difference between damaged coral reefs and no reefs whatsoever, between thinning forests and forests enveloped by desert, between catastrophe and chaos.
  • The discrepancy between the models, Arakawa concluded, came down to ice and snow. The whiteness of the world’s snowfields reflected light; if snow melted in a warmer climate, less radiation would escape the atmosphere, leading to even greater warming. Shortly before dawn, Arakawa concluded that Manabe had given too little weight to the influence of melting sea ice, while Hansen had overemphasized it. The best estimate lay in between. Which meant that the Jasons’ calculation was too optimistic. When carbon dioxide doubled in 2035 or thereabouts, global temperatures would increase between 1.5 and 4.5 degrees Celsius, with the most likely outcome a warming of three degrees.
  • within the highest levels of the federal government, the scientific community and the oil-and-gas industry — within the commonwealth of people who had begun to concern themselves with the future habitability of the planet — the Charney report would come to have the authority of settled fact. It was the summation of all the predictions that had come before, and it would withstand the scrutiny of the decades that followed it. Charney’s group had considered everything known about ocean, sun, sea, air and fossil fuels and had distilled it to a single number: three. When the doubling threshold was broached, as appeared inevitable, the world would warm three degrees Celsius
  • The last time the world was three degrees warmer was during the Pliocene, three million years ago, when beech trees grew in Antarctica, the seas were 80 feet higher and horses galloped across the Canadian coast of the Arctic Ocean.
  • After the publication of the Charney report, Exxon decided to create its own dedicated carbon-dioxide research program, with an annual budget of $600,000. Only Exxon was asking a slightly different question than Jule Charney. Exxon didn’t concern itself primarily with how much the world would warm. It wanted to know how much of the warming Exxon could be blamed for.
  • “It behooves us to start a very aggressive defensive program,” Shaw wrote in a memo to a manager, “because there is a good probability that legislation affecting our business will be passed.”
  • Shaw turned to Wallace Broecker, a Columbia University oceanographer who was the second author of Roger Revelle’s 1965 carbon-dioxide report for Lyndon Johnson. In 1977, in a presentation at the American Geophysical Union, Broecker predicted that fossil fuels would have to be restricted, whether by taxation or fiat. More recently, he had testified before Congress, calling carbon dioxide “the No.1 long-term environmental problem.” If presidents and senators trusted Broecker to tell them the bad news, he was good enough for Exxon.
  • The company had been studying the carbon-dioxide problem for decades, since before it changed its name to Exxon. In 1957, scientists from Humble Oil published a study tracking “the enormous quantity of carbon dioxide” contributed to the atmosphere since the Industrial Revolution “from the combustion of fossil fuels.” Even then, the observation that burning fossil fuels had increased the concentration of carbon in the atmosphere was well understood and accepted by Humble’s scientists.
  • The American Petroleum Institute, the industry’s largest trade association, asked the same question in 1958 through its air-pollution study group and replicated the findings made by Humble Oil. So did another A.P.I. study conducted by the Stanford Research Institute a decade later, in 1968, which concluded that the burning of fossil fuels would bring “significant temperature changes” by the year 2000 and ultimately “serious worldwide environmental changes,” including the melting of the Antarctic ice cap and rising seas.
  • The ritual repeated itself every few years. Industry scientists, at the behest of their corporate bosses, reviewed the problem and found good reasons for alarm and better excuses to do nothing. Why should they act when almost nobody within the United States government — nor, for that matter, within the environmental movement — seemed worried?
  • Why take on an intractable problem that would not be detected until this generation of employees was safely retired? Worse, the solutions seemed more punitive than the problem itself. Historically, energy use had correlated to economic growth — the more fossil fuels we burned, the better our lives became. Why mess with that?
  • That June, Jimmy Carter signed the Energy Security Act of 1980, which directed the National Academy of Sciences to start a multiyear, comprehensive study, to be called “Changing Climate,” that would analyze social and economic effects of climate change. More urgent, the National Commission on Air Quality, at the request of Congress, invited two dozen experts, including Henry Shaw himself, to a meeting in Florida to propose climate policy.
  • On April 3, 1980, Senator Paul Tsongas, a Massachusetts Democrat, held the first congressional hearing on carbon-dioxide buildup in the atmosphere. Gordon MacDonald testified that the United States should “take the initiative” and develop, through the United Nations, a way to coordinate every nation’s energy policies to address the problem.
  • During the expansion of the Clean Air Act, he pushed for the creation of the National Commission on Air Quality, charged with ensuring that the goals of the act were being met. One such goal was a stable global climate. The Charney report had made clear that goal was not being met, and now the commission wanted to hear proposals for legislation. It was a profound responsibility, and the two dozen experts invited to the Pink Palace — policy gurus, deep thinkers, an industry scientist and an environmental activist — had only three days to achieve it, but the utopian setting made everything seem possible
  • We have less time than we realize, said an M.I.T. nuclear engineer named David Rose, who studied how civilizations responded to large technological crises. “People leave their problems until the 11th hour, the 59th minute,” he said. “And then: ‘Eloi, Eloi, Lama Sabachthani?’ ” — “My God, my God, why hast thou forsaken me?”
  • The attendees seemed to share a sincere interest in finding solutions. They agreed that some kind of international treaty would ultimately be needed to keep atmospheric carbon dioxide at a safe level. But nobody could agree on what that level was.
  • William Elliott, a NOAA scientist, introduced some hard facts: If the United States stopped burning carbon that year, it would delay the arrival of the doubling threshold by only five years. If Western nations somehow managed to stabilize emissions, it would forestall the inevitable by only eight years. The only way to avoid the worst was to stop burning coal. Yet China, the Soviet Union and the United States, by far the world’s three largest coal producers, were frantically accelerating extraction.
  • “Do we have a problem?” asked Anthony Scoville, a congressional science consultant. “We do, but it is not the atmospheric problem. It is the political problem.” He doubted that any scientific report, no matter how ominous its predictions, would persuade politicians to act.
  • The talk of ending oil production stirred for the first time the gentleman from Exxon. “I think there is a transition period,” Henry Shaw said. “We are not going to stop burning fossil fuels and start looking toward solar or nuclear fusion and so on. We are going to have a very orderly transition from fossil fuels to renewable energy sources.”
  • What if the problem was that they were thinking of it as a problem? “What I am saying,” Scoville continued, “is that in a sense we are making a transition not only in energy but the economy as a whole.” Even if the coal and oil industries collapsed, renewable technologies like solar energy would take their place. Jimmy Carter was planning to invest $80 billion in synthetic fuel. “My God,” Scoville said, “with $80 billion, you could have a photovoltaics industry going that would obviate the need for synfuels forever!”
  • nobody could agree what to do. John Perry, a meteorologist who had worked as a staff member on the Charney report, suggested that American energy policy merely “take into account” the risks of global warming, though he acknowledged that a nonbinding measure might seem “intolerably stodgy.” “It is so weak,” Pomerance said, the air seeping out of him, “as to not get us anywhere.”
  • Scoville pointed out that the United States was responsible for the largest share of global carbon emissions. But not for long. “If we’re going to exercise leadership,” he said, “the opportunity is now.
  • One way to lead, he proposed, would be to classify carbon dioxide as a pollutant under the Clean Air Act and regulate it as such. This was received by the room like a belch. By Scoville’s logic, every sigh was an act of pollution. Did the science really support such an extreme measure? The Charney report did exactly that, Pomerance said.
  • Slade, the director of the Energy Department’s carbon-dioxide program, considered the lag a saving grace. If changes did not occur for a decade or more, he said, those in the room couldn’t be blamed for failing to prevent them. So what was the problem?
  • “Call it whatever.” Besides, Pomerance added, they didn’t have to ban coal tomorrow. A pair of modest steps could be taken immediately to show the world that the United States was serious: the implementation of a carbon tax and increased investment in renewable energy. Then the United States could organize an international summit meeting to address climate change
  • these two dozen experts, who agreed on the major points and had made a commitment to Congress, could not draft a single paragraph. Hours passed in a hell of fruitless negotiation, self-defeating proposals and impulsive speechifying. Pomerance and Scoville pushed to include a statement calling for the United States to “sharply accelerate international dialogue,” but they were sunk by objections and caveats.
  • They never got to policy proposals. They never got to the second paragraph. The final statement was signed by only the moderator, who phrased it more weakly than the declaration calling for the workshop in the first place. “The guide I would suggest,” Jorling wrote, “is whether we know enough not to recommend changes in existing policy.”
  • Pomerance had seen enough. A consensus-based strategy would not work — could not work — without American leadership. And the United States wouldn’t act unless a strong leader persuaded it to do so — someone who would speak with authority about the science, demand action from those in power and risk everything in pursuit of justice.
  • The meeting ended Friday morning. On Tuesday, four days later, Ronald Reagan was elected president.
  • ‘Otherwise, They’ll Gurgle’ November 1980-September 1981
  • In the midst of this carnage, the Council on Environmental Quality submitted a report to the White House warning that fossil fuels could “permanently and disastrously” alter Earth’s atmosphere, leading to “a warming of the Earth, possibly with very serious effects.” Reagan did not act on the council’s advice. Instead, his administration considered eliminating the council.
  • After the election, Reagan considered plans to close the Energy Department, increase coal production on federal land and deregulate surface coal mining. Once in office, he appointed James Watt, the president of a legal firm that fought to open public lands to mining and drilling, to run the Interior Department. “We’re deliriously happy,” the president of the National Coal Association was reported to have said. Reagan preserved the E.P.A. but named as its administrator Anne Gorsuch, an anti-regulation zealot who proceeded to cut the agency’s staff and budget by about a quarter
  • Reagan “has declared open war on solar energy,” the director of the nation’s lead solar-energy research agency said, after he was asked to resign). Reagan appeared determined to reverse the environmental achievements of Jimmy Carter, before undoing those of Richard Nixon, Lyndon Johnson, John F. Kennedy and, if he could get away with it, Theodore Roosevelt.
  • When Reagan considered closing the Council on Environmental Quality, its acting chairman, Malcolm Forbes Baldwin, wrote to the vice president and the White House chief of staff begging them to reconsider; in a major speech the same week, “A Conservative’s Program for the Environment,” Baldwin argued that it was “time for today’s conservatives explicitly to embrace environmentalism.” Environmental protection was not only good sense. It was good business. What could be more conservative than an efficient use of resources that led to fewer federal subsidies?
  • Meanwhile the Charney report continued to vibrate at the periphery of public consciousness. Its conclusions were confirmed by major studies from the Aspen Institute, the International Institute for Applied Systems Analysis near Vienna and the American Association for the Advancement of Science. Every month or so, nationally syndicated articles appeared summoning apocalypse: “Another Warning on ‘Greenhouse Effect,’ ” “Global Warming Trend ‘Beyond Human Experience,’ ” “Warming Trend Could ‘Pit Nation Against Nation.’
  • Pomerance read on the front page of The New York Times on Aug. 22, 1981, about a forthcoming paper in Science by a team of seven NASA scientists. They had found that the world had already warmed in the past century. Temperatures hadn’t increased beyond the range of historical averages, but the scientists predicted that the warming signal would emerge from the noise of routine weather fluctuations much sooner than previously expected. Most unusual of all, the paper ended with a policy recommendation: In the coming decades, the authors wrote, humankind should develop alternative sources of energy and use fossil fuels only “as necessary.” The lead author was James Hansen.
  • Pomerance listened and watched. He understood Hansen’s basic findings well enough: Earth had been warming since 1880, and the warming would reach “almost unprecedented magnitude” in the next century, leading to the familiar suite of terrors, including the flooding of a 10th of New Jersey and a quarter of Louisiana and Florida. But Pomerance was excited to find that Hansen could translate the complexities of atmospheric science into plain English.
  • 7. ‘We’re All Going to Be the Victims’ March 1982
  • Gore had learned about climate change a dozen years earlier as an undergraduate at Harvard, when he took a class taught by Roger Revelle. Humankind was on the brink of radically transforming the global atmosphere, Revelle explained, drawing Keeling’s rising zigzag on the blackboard, and risked bringing about the collapse of civilization. Gore was stunned: Why wasn’t anyone talking about this?
  • Most in Congress considered the science committee a legislative backwater, if they considered it at all; this made Gore’s subcommittee, which had no legislative authority, an afterthought to an afterthought. That, Gore vowed, would change. Environmental and health stories had all the elements of narrative drama: villains, victims and heroes. In a hearing, you could summon all three, with the chairman serving as narrator, chorus and moral authority. He told his staff director that he wanted to hold a hearing every week.
  • The Revelle hearing went as Grumbly had predicted. The urgency of the issue was lost on Gore’s older colleagues, who drifted in and out while the witnesses testified. There were few people left by the time the Brookings Institution economist Lester Lave warned that humankind’s profligate exploitation of fossil fuels posed an existential test to human nature. “Carbon dioxide stands as a symbol now of our willingness to confront the future,” he said. “It will be a sad day when we decide that we just don’t have the time or thoughtfulness to address those issues.”
  • That night, the news programs featured the resolution of the baseball strike, the ongoing budgetary debate and the national surplus of butter.
  • There emerged, despite the general comity, a partisan divide. Unlike the Democrats, the Republicans demanded action. “Today I have a sense of déjà vu,” said Robert Walker, a Republican from Pennsylvania. In each of the last five years, he said, “we have been told and told and told that there is a problem with the increasing carbon dioxide in the atmosphere. We all accept that fact, and we realize that the potential consequences are certainly major in their impact on mankind.” Yet they had failed to propose a single law. “Now is the time,” he said. “The research is clear. It is up to us now to summon the political will.”
  • Hansen flew to Washington to testify on March 25, 1982, performing before a gallery even more thinly populated than at Gore’s first hearing on the greenhouse effect. Gore began by attacking the Reagan administration for cutting funding for carbon-dioxide research despite the “broad consensus in the scientific community that the greenhouse effect is a reality.” William Carney, a Republican from New York, bemoaned the burning of fossil fuels and argued passionately that science should serve as the basis for legislative policy
  • the experts invited by Gore agreed with the Republicans: The science was certain enough. Melvin Calvin, a Berkeley chemist who won the Nobel Prize for his work on the carbon cycle, said that it was useless to wait for stronger evidence of warming. “You cannot do a thing about it when the signals are so big that they come out of the noise,” he said. “You have to look for early warning signs.”
  • Hansen’s job was to share the warning signs, to translate the data into plain English. He explained a few discoveries that his team had made — not with computer models but in libraries. By analyzing records from hundreds of weather stations, he found that the surface temperature of the planet had already increased four-tenths of a degree Celsius in the previous century. Data from several hundred tide-gauge stations showed that the oceans had risen four inches since the 1880s
  • It occurred to Hansen that this was the only political question that mattered: How long until the worst began? It was not a question on which geophysicists expended much effort; the difference between five years and 50 years in the future was meaningless in geologic time. Politicians were capable of thinking only in terms of electoral time: six years, four years, two years. But when it came to the carbon problem, the two time schemes were converging.
  • “Within 10 or 20 years,” Hansen said, “we will see climate changes which are clearly larger than the natural variability.” James Scheuer wanted to make sure he understood this correctly. No one else had predicted that the signal would emerge that quickly. “If it were one or two degrees per century,” he said, “that would be within the range of human adaptability. But we are pushing beyond the range of human adaptability.” “Yes,” Hansen said.
  • How soon, Scheuer asked, would they have to change the national model of energy production? Hansen hesitated — it wasn’t a scientific question. But he couldn’t help himself. He had been irritated, during the hearing, by all the ludicrous talk about the possibility of growing more trees to offset emissions. False hopes were worse than no hope at all: They undermined the prospect of developing real solutions. “That time is very soon,” Hansen said finally. “My opinion is that it is past,” Calvin said, but he was not heard because he spoke from his seat. He was told to speak into the microphone. “It is already later,” Calvin said, “than you think.”
  • From Gore’s perspective, the hearing was an unequivocal success. That night Dan Rather devoted three minutes of “CBS Evening News” to the greenhouse effect. A correspondent explained that temperatures had increased over the previous century, great sheets of pack ice in Antarctica were rapidly melting, the seas were rising; Calvin said that “the trend is all in the direction of an impending catastrophe”; and Gore mocked Reagan for his shortsightedness. Later, Gore could take credit for protecting the Energy Department’s carbon-dioxide program, which in the end was largely preserved.
  • 8. ‘The Direction of an Impending Catastrophe’ 1982
  • Following Henry Shaw’s recommendation to establish credibility ahead of any future legislative battles, Exxon had begun to spend conspicuously on global-warming research. It donated tens of thousands of dollars to some of the most prominent research efforts, including one at Woods Hole led by the ecologist George Woodwell, who had been calling for major climate policy as early as the mid-1970s, and an international effort coordinated by the United Nations. Now Shaw offered to fund the October 1982 symposium on climate change at Columbia’s Lamont-Doherty campus.
  • David boasted that Exxon would usher in a new global energy system to save the planet from the ravages of climate change. He went so far as to argue that capitalism’s blind faith in the wisdom of the free market was “less than satisfying” when it came to the greenhouse effect. Ethical considerations were necessary, too. He pledged that Exxon would revise its corporate strategy to account for climate change, even if it were not “fashionable” to do so. As Exxon had already made heavy investments in nuclear and solar technology, he was “generally upbeat” that Exxon would “invent” a future of renewable energy.
  • Hansen had reason to feel upbeat himself. If the world’s largest oil-and-gas company supported a new national energy model, the White House would not stand in its way. The Reagan administration was hostile to change from within its ranks. But it couldn’t be hostile to Exxon.
  • The carbon-dioxide issue was beginning to receive major national attention — Hansen’s own findings had become front-page news, after all. What started as a scientific story was turning into a political story.
  • The political realm was itself a kind of Mirror World, a parallel reality that crudely mimicked our own. It shared many of our most fundamental laws, like the laws of gravity and inertia and publicity. And if you applied enough pressure, the Mirror World of politics could be sped forward to reveal a new future. Hansen was beginning to understand that too.
  • 1. ‘Caution, Not Panic’ 1983-1984
  • in the fall of 1983, the climate issue entered an especially long, dark winter. And all because of a single report that had done nothing to change the state of climate science but transformed the state of climate politics.
  • After the publication of the Charney report in 1979, Jimmy Carter had directed the National Academy of Sciences to prepare a comprehensive, $1 million analysis of the carbon-dioxide problem: a Warren Commission for the greenhouse effect. A team of scientist-dignitaries — among them Revelle, the Princeton modeler Syukuro Manabe and the Harvard political economist Thomas Schelling, one of the intellectual architects of Cold War game theory — would review the literature, evaluate the consequences of global warming for the world order and propose remedies
  • Then Reagan won the White House.
  • the incipient report served as the Reagan administration’s answer to every question on the subject. There could be no climate policy, Fred Koomanoff and his associates said, until the academy ruled. In the Mirror World of the Reagan administration, the warming problem hadn’t been abandoned at all. A careful, comprehensive solution was being devised. Everyone just had to wait for the academy’s elders to explain what it was.
  • The committee’s chairman, William Nierenberg — a Jason, presidential adviser and director of Scripps, the nation’s pre-eminent oceanographic institution — argued that action had to be taken immediately, before all the details could be known with certainty, or else it would be too late.
  • Better to bet on American ingenuity to save the day. Major interventions in national energy policy, taken immediately, might end up being more expensive, and less effective, than actions taken decades in the future, after more was understood about the economic and social consequences of a warmer planet. Yes, the climate would change, mostly for the worst, but future generations would be better equipped to change with it.
  • Government officials who knew Nierenberg were not surprised by his conclusions: He was an optimist by training and experience, a devout believer in the doctrine of American exceptionalism, one of the elite class of scientists who had helped the nation win a global war, invent the most deadly weapon conceivable and create the booming aerospace and computer industries. America had solved every existential problem it had confronted over the previous generation; it would not be daunted by an excess of carbon dioxide. Nierenberg had also served on Reagan’s transition team. Nobody believed that he had been directly influenced by his political connections, but his views — optimistic about the saving graces of market forces, pessimistic about the value of government regulation — reflected all the ardor of his party.
  • That’s what Nierenberg wrote in “Changing Climate.” But it’s not what he said in the press interviews that followed. He argued the opposite: There was no urgent need for action. The public should not entertain the most “extreme negative speculations” about climate change (despite the fact that many of those speculations appeared in his report). Though “Changing Climate” urged an accelerated transition to renewable fuels, noting that it would take thousands of years for the atmosphere to recover from the damage of the last century, Nierenberg recommended “caution, not panic.” Better to wait and see
  • The damage of “Changing Climate” was squared by the amount of attention it received. Nierenberg’s speech in the Great Hall, being one-500th the length of the actual assessment, received 500 times the press coverage. As The Wall Street Journal put it, in a line echoed by trade journals across the nation: “A panel of top scientists has some advice for people worried about the much-publicized warming of the Earth’s climate: You can cope.”
  • On “CBS Evening News,” Dan Rather said the academy had given “a cold shoulder” to a grim, 200-page E.P.A. assessment published earlier that week (titled “Can We Delay a Greenhouse Warming?”; the E.P.A.’s answer, reduced to a word, was no). The Washington Post described the two reports, taken together, as “clarion calls to inaction.
  • George Keyworth II, Reagan’s science adviser. Keyworth used Nierenberg’s optimism as reason to discount the E.P.A.’s “unwarranted and unnecessarily alarmist” report and warned against taking any “near-term corrective action” on global warming. Just in case it wasn’t clear, Keyworth added, “there are no actions recommended other than continued research.”
  • Edward David Jr., two years removed from boasting of Exxon’s commitment to transforming global energy policy, told Science that the corporation had reconsidered. “Exxon has reverted to being mainly a supplier of conventional hydrocarbon fuels — petroleum products, natural gas and steam coal,” David said. The American Petroleum Institute canceled its own carbon-dioxide research program, too.
  • Exxon soon revised its position on climate-change research. In a presentation at an industry conference, Henry Shaw cited “Changing Climate” as evidence that “the general consensus is that society has sufficient time to technologically adapt to a CO₂ greenhouse effect.” If the academy had concluded that regulations were not a serious option, why should Exxon protest
  • 2. ‘You Scientists Win’ 1985
  • 3. The Size of The Human Imagination Spring-Summer 1986
  • Curtis Moore’s proposal: Use ozone to revive climate. The ozone hole had a solution — an international treaty, already in negotiation. Why not hitch the milk wagon to the bullet train? Pomerance was skeptical. The problems were related, sure: Without a reduction in CFC emissions, you didn’t have a chance of averting cataclysmic global warming. But it had been difficult enough to explain the carbon issue to politicians and journalists; why complicate the sales pitch? Then again, he didn’t see what choice he had. The Republicans controlled the Senate, and Moore was his connection to the Senate’s environmental committee.
  • Pomerance met with Senator John Chafee, a Republican from Rhode Island, and helped persuade him to hold a double-barreled hearing on the twin problems of ozone and carbon dioxide on June 10 and 11, 1986
  • F.Sherwood Rowland, Robert Watson, a NASA scientist, and Richard Benedick, the administration’s lead representative in international ozone negotiations, would discuss ozone; James Hansen, Al Gore, the ecologist George Woodwell and Carl Wunsch, a veteran of the Charney group, would testify about climate change.
  • As Pomerance had hoped, fear about the ozone layer ensured a bounty of press coverage for the climate-change testimony. But as he had feared, it caused many people to conflate the two crises. One was Peter Jennings, who aired the video on ABC’s “World News Tonight,” warning that the ozone hole “could lead to flooding all over the world, also to drought and to famine.”
  • The confusion helped: For the first time since the “Changing Climate” report, global-warming headlines appeared by the dozen. William Nierenberg’s “caution, not panic” line was inverted. It was all panic without a hint of caution: “A Dire Forecast for ‘Greenhouse’ Earth” (the front page of The Washington Post); “Scientists Predict Catastrophes in Growing Global Heat Wave” (Chicago Tribune); “Swifter Warming of Globe Foreseen” (The New York Times).
  • After three years of backsliding and silence, Pomerance was exhilarated to see interest in the issue spike overnight. Not only that: A solution materialized, and a moral argument was passionately articulated — by Rhode Island’s Republican senator no less. “Ozone depletion and the greenhouse effect can no longer be treated solely as important scientific questions,” Chafee said. “They must be seen as critical problems facing the nations of the world, and they are problems that demand solutions.”
  • The old canard about the need for more research was roundly mocked — by Woodwell, by a W.R.I. colleague named Andrew Maguire, by Senator George Mitchell, a Democrat from Maine. “Scientists are never 100 percent certain,” the Princeton historian Theodore Rabb testified. “That notion of total certainty is something too elusive ever to be sought.” As Pomerance had been saying since 1979, it was past time to act. Only now the argument was so broadly accepted that nobody dared object.
  • The ozone hole, Pomerance realized, had moved the public because, though it was no more visible than global warming, people could be made to see it. They could watch it grow on video. Its metaphors were emotionally wrought: Instead of summoning a glass building that sheltered plants from chilly weather (“Everything seems to flourish in there”), the hole evoked a violent rending of the firmament, inviting deathly radiation. Americans felt that their lives were in danger. An abstract, atmospheric problem had been reduced to the size of the human imagination. It had been made just small enough, and just large enough, to break through.
  • Four years after “Changing Climate,” two years after a hole had torn open the firmament and a month after the United States and more than three dozen other nations signed a treaty to limit use of CFCs, the climate-change corps was ready to celebrate. It had become conventional wisdom that climate change would follow ozone’s trajectory. Reagan’s E.P.A. administrator, Lee M. Thomas, said as much the day he signed the Montreal Protocol on Substances That Deplete the Ozone Layer (the successor to the Vienna Convention), telling reporters that global warming was likely to be the subject of a future international agreement
  • Congress had already begun to consider policy — in 1987 alone, there were eight days of climate hearings, in three committees, across both chambers of Congress; Senator Joe Biden, a Delaware Democrat, had introduced legislation to establish a national climate-change strategy. And so it was that Jim Hansen found himself on Oct. 27 in the not especially distinguished ballroom of the Quality Inn on New Jersey Avenue, a block from the Capitol, at “Preparing for Climate Change,” which was technically a conference but felt more like a wedding.
  • John Topping was an old-line Rockefeller Republican, a Commerce Department lawyer under Nixon and an E.P.A. official under Reagan. He first heard about the climate problem in the halls of the E.P.A. in 1982 and sought out Hansen, who gave him a personal tutorial. Topping was amazed to discover that out of the E.P.A.’s 13,000-person staff, only seven people, by his count, were assigned to work on climate, though he figured it was more important to the long-term security of the nation than every other environmental issue combined.
  • Glancing around the room, Jim Hansen could chart, like an arborist counting rings on a stump, the growth of the climate issue over the decade. Veterans like Gordon MacDonald, George Woodwell and the environmental biologist Stephen Schneider stood at the center of things. Former and current staff members from the congressional science committees (Tom Grumbly, Curtis Moore, Anthony Scoville) made introductions to the congressmen they advised. Hansen’s owlish nemesis Fred Koomanoff was present, as were his counterparts from the Soviet Union and Western Europe. Rafe Pomerance’s cranium could be seen above the crowd, but unusually he was surrounded by colleagues from other environmental organizations that until now had shown little interest in a diffuse problem with no proven fund-raising record. The party’s most conspicuous newcomers, however, the outermost ring, were the oil-and-gas executives.
  • That evening, as a storm spat and coughed outside, Rafe Pomerance gave one of his exhortative speeches urging cooperation among the various factions, and John Chafee and Roger Revelle received awards; introductions were made and business cards earnestly exchanged. Not even a presentation by Hansen of his research could sour the mood. The next night, on Oct. 28, at a high-spirited dinner party in Topping’s townhouse on Capitol Hill, the oil-and-gas men joked with the environmentalists, the trade-group representatives chatted up the regulators and the academics got merrily drunk. Mikhail Budyko, the don of the Soviet climatologists, settled into an extended conversation about global warming with Topping’s 10-year-old son. It all seemed like the start of a grand bargain, a uniting of factions — a solution.
  • Hansen was accustomed to the bureaucratic nuisances that attended testifying before Congress; before a hearing, he had to send his formal statement to NASA headquarters, which forwarded it to the White House’s Office of Management and Budget for approval. “Major greenhouse climate changes are a certainty,” he had written. “By the 2010s [in every scenario], essentially the entire globe has very substantial warming.”
  • By all appearances, plans for major policy continued to advance rapidly. After the Johnston hearing, Timothy Wirth, a freshman Democratic senator from Colorado on the energy committee, began to plan a comprehensive package of climate-change legislation — a New Deal for global warming. Wirth asked a legislative assistant, David Harwood, to consult with experts on the issue, beginning with Rafe Pomerance, in the hope of converting the science of climate change into a new national energy policy.
  • In March 1988, Wirth joined 41 other senators, nearly half of them Republicans, to demand that Reagan call for an international treaty modeled after the ozone agreement. Because the United States and the Soviet Union were the world’s two largest contributors of carbon emissions, responsible for about one-third of the world total, they should lead the negotiations. Reagan agreed. In May, he signed a joint statement with Mikhail Gorbachev that included a pledge to cooperate on global warming.
  • Al Gore himself had, for the moment, withdrawn his political claim to the issue. In 1987, at the age of 39, Gore announced that he was running for president, in part to bring attention to global warming, but he stopped emphasizing it after the subject failed to captivate New Hampshire primary voters.
  • 5. ‘You Will See Things That You Shall Believe’ Summer 1988
  • It was the hottest and driest summer in history. Everywhere you looked, something was bursting into flames. Two million acres in Alaska incinerated, and dozens of major fires scored the West. Yellowstone National Park lost nearly one million acres. Smoke was visible from Chicago, 1,600 miles away.
  • In Nebraska, suffering its worst drought since the Dust Bowl, there were days when every weather station registered temperatures above 100 degrees. The director of the Kansas Department of Health and Environment warned that the drought might be the dawning of a climatic change that within a half century could turn the state into a desert.
  • On June 22 in Washington, where it hit 100 degrees, Rafe Pomerance received a call from Jim Hansen, who was scheduled to testify the following morning at a Senate hearing called by Timothy Wirth. “I hope we have good media coverage tomorrow,” Hansen said.
  • Hansen had just received the most recent global temperature data. Just over halfway into the year, 1988 was setting records. Already it had nearly clinched the hottest year in history. Ahead of schedule, the signal was emerging from the noise. “I’m going to make a pretty strong statement,” Hansen said.
  • Hansen returned to his testimony. He wrote: “The global warming is now large enough that we can ascribe with a high degree of confidence a cause-and-effect relationship to the greenhouse effect.” He wrote: “1988 so far is so much warmer than 1987, that barring a remarkable and improbable cooling, 1988 will be the warmest year on record.” He wrote: “The greenhouse effect has been detected, and it is changing our climate now.”
  • “We have only one planet,” Senator Bennett Johnston intoned. “If we screw it up, we have no place to go.” Senator Max Baucus, a Democrat from Montana, called for the United Nations Environment Program to begin preparing a global remedy to the carbon-dioxide problem. Senator Dale Bumpers, a Democrat of Arkansas, previewed Hansen’s testimony, saying that it “ought to be cause for headlines in every newspaper in America tomorrow morning.” The coverage, Bumpers emphasized, was a necessary precursor to policy. “Nobody wants to take on any of the industries that produce the things that we throw up into the atmosphere,” he said. “But what you have are all these competing interests pitted against our very survival.”
  • Hansen, wiping his brow, spoke without affect, his eyes rarely rising from his notes. The warming trend could be detected “with 99 percent confidence,” he said. “It is changing our climate now.” But he saved his strongest comment for after the hearing, when he was encircled in the hallway by reporters. “It is time to stop waffling so much,” he said, “and say that the evidence is pretty strong that the greenhouse effect is here.”
  • The press followed Bumpers’s advice. Hansen’s testimony prompted headlines in dozens of newspapers across the country, including The New York Times, which announced, across the top of its front page: “Global Warming Has Begun, Expert Tells Senate.”
  • Rafe Pomerance called his allies on Capitol Hill, the young staff members who advised politicians, organized hearings, wrote legislation. We need to finalize a number, he told them, a specific target, in order to move the issue — to turn all this publicity into policy. The Montreal Protocol had called for a 50 percent reduction in CFC emissions by 1998. What was the right target for carbon emissions? It wasn’t enough to exhort nations to do better. That kind of talk might sound noble, but it didn’t change investments or laws. They needed a hard goal — something ambitious but reasonable. And they needed it soon: Just four days after Hansen’s star turn, politicians from 46 nations and more than 300 scientists would convene in Toronto at the World Conference on the Changing Atmosphere, an event described by Philip Shabecoff of The New York Times as “Woodstock for climate change.”
  • Pomerance had a proposal: a 20 percent reduction in carbon emissions by 2000. Ambitious, Harwood said. In all his work planning climate policy, he had seen no assurance that such a steep drop in emissions was possible. Then again, 2000 was more than a decade off, so it allowed for some flexibility.
  • Mintzer pointed out that a 20 percent reduction was consistent with the academic literature on energy efficiency. Various studies over the years had shown that you could improve efficiency in most energy systems by roughly 20 percent if you adopted best practices.
  • Of course, with any target, you had to take into account the fact that the developing world would inevitably consume much larger quantities of fossil fuels by 2000. But those gains could be offset by a wider propagation of the renewable technologies already at hand — solar, wind, geothermal. It was not a rigorous scientific analysis, Mintzer granted, but 20 percent sounded plausible. We wouldn’t need to solve cold fusion or ask Congress to repeal the law of gravity. We could manage it with the knowledge and technology we already had.
  • Besides, Pomerance said, 20 by 2000 sounds good.
  • The conference’s final statement, signed by all 400 scientists and politicians in attendance, repeated the demand with a slight variation: a 20 percent reduction in carbon emissions by 2005. Just like that, Pomerance’s best guess became global diplomatic policy.
  • Hansen, emerging from Anniek’s successful cancer surgery, took it upon himself to start a one-man public information campaign. He gave news conferences and was quoted in seemingly every article about the issue; he even appeared on television with homemade props. Like an entrant at an elementary-school science fair, he made “loaded dice” out of sections of cardboard and colored paper to illustrate the increased likelihood of hotter weather in a warmer climate. Public awareness of the greenhouse effect reached a new high of 68 percent
  • global warming became a major subject of the presidential campaign. While Michael Dukakis proposed tax incentives to encourage domestic oil production and boasted that coal could satisfy the nation’s energy needs for the next three centuries, George Bush took advantage. “I am an environmentalist,” he declared on the shore of Lake Erie, the first stop on a five-state environmental tour that would take him to Boston Harbor, Dukakis’s home turf. “Those who think we are powerless to do anything about the greenhouse effect,” he said, “are forgetting about the White House effect.”
  • His running mate emphasized the ticket’s commitment to the issue at the vice-presidential debate. “The greenhouse effect is an important environmental issue,” Dan Quayle said. “We need to get on with it. And in a George Bush administration, you can bet that we will.”
  • This kind of talk roused the oil-and-gas men. “A lot of people on the Hill see the greenhouse effect as the issue of the 1990s,” a gas lobbyist told Oil & Gas Journal. Before a meeting of oil executives shortly after the “environmentalist” candidate won the election, Representative Dick Cheney, a Wyoming Republican, warned, “It’s going to be very difficult to fend off some kind of gasoline tax.” The coal industry, which had the most to lose from restrictions on carbon emissions, had moved beyond denial to resignation. A spokesman for the National Coal Association acknowledged that the greenhouse effect was no longer “an emerging issue. It is here already, and we’ll be hearing more and more about it.”
  • By the end of the year, 32 climate bills had been introduced in Congress, led by Wirth’s omnibus National Energy Policy Act of 1988. Co-sponsored by 13 Democrats and five Republicans, it established as a national goal an “International Global Agreement on the Atmosphere by 1992,” ordered the Energy Department to submit to Congress a plan to reduce energy use by at least 2 percent a year through 2005 and directed the Congressional Budget Office to calculate the feasibility of a carbon tax. A lawyer for the Senate energy committee told an industry journal that lawmakers were “frightened” by the issue and predicted that Congress would eventually pass significant legislation after Bush took office
  • The other great powers refused to wait. The German Parliament created a special commission on climate change, which concluded that action had to be taken immediately, “irrespective of any need for further research,” and that the Toronto goal was inadequate; it recommended a 30 percent reduction of carbon emissions
  • Margaret Thatcher, who had studied chemistry at Oxford, warned in a speech to the Royal Society that global warming could “greatly exceed the capacity of our natural habitat to cope” and that “the health of the economy and the health of our environment are totally dependent upon each other.”
  • The prime ministers of Canada and Norway called for a binding international treaty on the atmosphere; Sweden’s Parliament went further, announcing a national strategy to stabilize emissions at the 1988 level and eventually imposing a carbon tax
  • the United Nations unanimously endorsed the establishment, by the World Meteorological Organization and the United Nations Environment Program, of an Intergovernmental Panel on Climate Change, composed of scientists and policymakers, to conduct scientific assessments and develop global climate policy.
  • One of the I.P.C.C.’s first sessions to plan an international treaty was hosted by the State Department, 10 days after Bush’s inauguration. James Baker chose the occasion to make his first speech as secretary of state. “We can probably not afford to wait until all of the uncertainties about global climate change have been resolved,” he said. “Time will not make the problem go away.”
  • : On April 14, 1989, a bipartisan group of 24 senators, led by the majority leader, George Mitchell, requested that Bush cut emissions in the United States even before the I.P.C.C.’s working group made its recommendation. “We cannot afford the long lead times associated with a comprehensive global agreement,” the senators wrote. Bush had promised to combat the greenhouse effect with the White House effect. The self-proclaimed environmentalist was now seated in the Oval Office. It was time.
  • 8. ‘You Never Beat The White House’ April 1989
  • After Jim Baker gave his boisterous address to the I.P.C.C. working group at the State Department, he received a visit from John Sununu, Bush’s chief of staff. Leave the science to the scientists, Sununu told Baker. Stay clear of this greenhouse-effect nonsense. You don’t know what you’re talking about. Baker, who had served as Reagan’s chief of staff, didn’t speak about the subject again.
  • despite his reputation as a political wolf, he still thought of himself as a scientist — an “old engineer,” as he was fond of putting it, having earned a Ph.D. in mechanical engineering from M.I.T. decades earlier. He lacked the reflexive deference that so many of his political generation reserved for the class of elite government scientists.
  • Since World War II, he believed, conspiratorial forces had used the imprimatur of scientific knowledge to advance an “anti-growth” doctrine. He reserved particular disdain for Paul Ehrlich’s “The Population Bomb,” which prophesied that hundreds of millions of people would starve to death if the world took no step to curb population growth; the Club of Rome, an organization of European scientists, heads of state and economists, which similarly warned that the world would run out of natural resources; and as recently as the mid-’70s, the hypothesis advanced by some of the nation’s most celebrated scientists — including Carl Sagan, Stephen Schneider and Ichtiaque Rasool — that a new ice age was dawning, thanks to the proliferation of man-made aerosols. All were theories of questionable scientific merit, portending vast, authoritarian remedies to halt economic progress.
  • When Mead talked about “far-reaching” decisions and “long-term consequences,” Sununu heard the marching of jackboots.
  • Sununu had suspected that the greenhouse effect belonged to this nefarious cabal since 1975, when the anthropologist Margaret Mead convened a symposium on the subject at the National Institute of Environmental Health Sciences.
  • While Sununu and Darman reviewed Hansen’s statements, the E.P.A. administrator, William K. Reilly, took a new proposal to the White House. The next meeting of the I.P.C.C.’s working group was scheduled for Geneva the following month, in May; it was the perfect occasion, Reilly argued, to take a stronger stand on climate change. Bush should demand a global treaty to reduce carbon emissions.
  • Sununu wouldn’t budge. He ordered the American delegates not to make any commitment in Geneva. Very soon after that, someone leaked the exchange to the press.
  • A deputy of Jim Baker pulled Reilly aside. He said he had a message from Baker, who had observed Reilly’s infighting with Sununu. “In the long run,” the deputy warned Reilly, “you never beat the White House.”
  • 9. ‘A Form of Science Fraud’ May 1989
  • The cameras followed Hansen and Gore into the marbled hallway. Hansen insisted that he wanted to focus on the science. Gore focused on the politics. “I think they’re scared of the truth,” he said. “They’re scared that Hansen and the other scientists are right and that some dramatic policy changes are going to be needed, and they don’t want to face up to it.”
  • The censorship did more to publicize Hansen’s testimony and the dangers of global warming than anything he could have possibly said. At the White House briefing later that morning, Press Secretary Marlin Fitzwater admitted that Hansen’s statement had been changed. He blamed an official “five levels down from the top” and promised that there would be no retaliation. Hansen, he added, was “an outstanding and distinguished scientist” and was “doing a great job.”
  • 10. The White House Effect Fall 1989
  • The Los Angeles Times called the censorship “an outrageous assault.” The Chicago Tribune said it was the beginning of “a cold war on global warming,” and The New York Times warned that the White House’s “heavy-handed intervention sends the signal that Washington wants to go slow on addressing the greenhouse problem.”
  • Darman went to see Sununu. He didn’t like being accused of censoring scientists. They needed to issue some kind of response. Sununu called Reilly to ask if he had any ideas. We could start, Reilly said, by recommitting to a global climate treaty. The United States was the only Western nation on record as opposing negotiations.
  • Sununu sent a telegram to Geneva endorsing a plan “to develop full international consensus on necessary steps to prepare for a formal treaty-negotiating process. The scope and importance of this issue are so great that it is essential for the U.S. to exercise leadership.”
  • Sununu seethed at any mention of the subject. He had taken it upon himself to study more deeply the greenhouse effect; he would have a rudimentary, one-dimensional general circulation model installed on his personal desktop computer. He decided that the models promoted by Jim Hansen were a lot of bunk. They were horribly imprecise in scale and underestimated the ocean’s ability to mitigate warming. Sununu complained about Hansen to D. Allan Bromley, a nuclear physicist from Yale who, at Sununu’s recommendation, was named Bush’s science adviser. Hansen’s findings were “technical poppycock” that didn’t begin to justify such wild-eyed pronouncements that “the greenhouse effect is here” or that the 1988 heat waves could be attributed to global warming, let alone serve as the basis for national economic policy.
  • When a junior staff member in the Energy Department, in a meeting at the White House with Sununu and Reilly, mentioned an initiative to reduce fossil-fuel use, Sununu interrupted her. “Why in the world would you need to reduce fossil-fuel use?” he asked. “Because of climate change,” the young woman replied. “I don’t want anyone in this administration without a scientific background using ‘climate change’ or ‘global warming’ ever again,” he said. “If you don’t have a technical basis for policy, don’t run around making decisions on the basis of newspaper headlines.” After the meeting, Reilly caught up to the staff member in the hallway. She was shaken. Don’t take it personally, Reilly told her. Sununu might have been looking at you, but that was directed at me.
  • Reilly, for his part, didn’t entirely blame Sununu for Bush’s indecision on the prospect of a climate treaty. The president had never taken a vigorous interest in global warming and was mainly briefed about it by nonscientists. Bush had brought up the subject on the campaign trail, in his speech about the White House effect, after leafing through a briefing booklet for a new issue that might generate some positive press. When Reilly tried in person to persuade him to take action, Bush deferred to Sununu and Baker. Why don’t the three of you work it out, he said. Let me know when you decide
  • Relations between Sununu and Reilly became openly adversarial. Reilly, Sununu thought, was a creature of the environmental lobby. He was trying to impress his friends at the E.P.A. without having a basic grasp of the science himself.
  • Pomerance had the sinking feeling that the momentum of the previous year was beginning to flag. The censoring of Hansen’s testimony and the inexplicably strident opposition from John Sununu were ominous signs. So were the findings of a report Pomerance had commissioned, published in September by the World Resources Institute, tracking global greenhouse-gas emissions. The United States was the largest contributor by far, producing nearly a quarter of the world’s carbon emissions, and its contribution was growing faster than that of every other country. Bush’s indecision, or perhaps inattention, had already managed to delay the negotiation of a global climate treaty until 1990 at the earliest, perhaps even 1991. By then, Pomerance worried, it would be too late.
  • Pomerance tried to be more diplomatic. “The president made a commitment to the American people to deal with global warming,” he told The Washington Post, “and he hasn’t followed it up.” He didn’t want to sound defeated. “There are some good building blocks here,” Pomerance said, and he meant it. The Montreal Protocol on CFCs wasn’t perfect at first, either — it had huge loopholes and weak restrictions. Once in place, however, the restrictions could be tightened. Perhaps the same could happen with climate change. Perhaps. Pomerance was not one for pessimism. As William Reilly told reporters, dutifully defending the official position forced upon him, it was the first time that the United States had formally endorsed the concept of an emissions limit. Pomerance wanted to believe that this was progress.
  • All week in Noordwijk, Becker couldn’t stop talking about what he had seen in Zeeland. After a flood in 1953, when the sea swallowed much of the region, killing more than 2,000 people, the Dutch began to build the Delta Works, a vast concrete-and-steel fortress of movable barriers, dams and sluice gates — a masterpiece of human engineering. The whole system could be locked into place within 90 minutes, defending the land against storm surge. It reduced the country’s exposure to the sea by 700 kilometers, Becker explained. The United States coastline was about 153,000 kilometers long. How long, he asked, was the entire terrestrial coastline? Because the whole world was going to need this. In Zeeland, he said, he had seen the future.
  • Ken Caldeira, a climate scientist at the Carnegie Institution for Science in Stanford, Calif., has a habit of asking new graduate students to name the largest fundamental breakthrough in climate physics since 1979. It’s a trick question. There has been no breakthrough. As with any mature scientific discipline, there is only refinement. The computer models grow more precise; the regional analyses sharpen; estimates solidify into observational data. Where there have been inaccuracies, they have tended to be in the direction of understatement.
  • More carbon has been released into the atmosphere since the final day of the Noordwijk conference, Nov. 7, 1989, than in the entire history of civilization preceding it
  • Despite every action taken since the Charney report — the billions of dollars invested in research, the nonbinding treaties, the investments in renewable energy — the only number that counts, the total quantity of global greenhouse gas emitted per year, has continued its inexorable rise.
  • When it comes to our own nation, which has failed to make any binding commitments whatsoever, the dominant narrative for the last quarter century has concerned the efforts of the fossil-fuel industries to suppress science, confuse public knowledge and bribe politicians.
  • The mustache-twirling depravity of these campaigns has left the impression that the oil-and-gas industry always operated thus; while the Exxon scientists and American Petroleum Institute clerics of the ’70s and ’80s were hardly good Samaritans, they did not start multimillion-dollar disinformation campaigns, pay scientists to distort the truth or try to brainwash children in elementary schools, as their successors would.
  • It was James Hansen’s testimony before Congress in 1988 that, for the first time since the “Changing Climate” report, made oil-and-gas executives begin to consider the issue’s potential to hurt their profits. Exxon, as ever, led the field. Six weeks after Hansen’s testimony, Exxon’s manager of science and strategy development, Duane LeVine, prepared an internal strategy paper urging the company to “emphasize the uncertainty in scientific conclusions.” This shortly became the default position of the entire sector. LeVine, it so happened, served as chairman of the global petroleum industry’s Working Group on Global Climate Change, created the same year, which adopted Exxon’s position as its own
  • The American Petroleum Institute, after holding a series of internal briefings on the subject in the fall and winter of 1988, including one for the chief executives of the dozen or so largest oil companies, took a similar, if slightly more diplomatic, line. It set aside money for carbon-dioxide policy — about $100,000, a fraction of the millions it was spending on the health effects of benzene, but enough to establish a lobbying organization called, in an admirable flourish of newspeak, the Global Climate Coalition.
  • The G.C.C. was conceived as a reactive body, to share news of any proposed regulations, but on a whim, it added a press campaign, to be coordinated mainly by the A.P.I. It gave briefings to politicians known to be friendly to the industry and approached scientists who professed skepticism about global warming. The A.P.I.’s payment for an original op-ed was $2,000.
  • It was joined by the U.S. Chamber of Commerce and 14 other trade associations, including those representing the coal, electric-grid and automobile industries
  • In October 1989, scientists allied with the G.C.C. began to be quoted in national publications, giving an issue that lacked controversy a convenient fulcrum. “Many respected scientists say the available evidence doesn’t warrant the doomsday warnings,” was the caveat that began to appear in articles on climate change.
  • The following year, when President Bill Clinton proposed an energy tax in the hope of meeting the goals of the Rio treaty, the A.P.I. invested $1.8 million in a G.C.C. disinformation campaign. Senate Democrats from oil-and-coal states joined Republicans to defeat the tax proposal, which later contributed to the Republicans’ rout of Democrats in the midterm congressional elections in 1994 — the first time the Republican Party had won control of both houses in 40 years
  • The G.C.C. spent $13 million on a single ad campaign intended to weaken support for the 1997 Kyoto Protocol, which committed its parties to reducing greenhouse-gas emissions by 5 percent relative to 1990 levels. The Senate, which would have had to ratify the agreement, took a pre-emptive vote declaring its opposition; the resolution passed 95-0. There has never been another serious effort to negotiate a binding global climate treaty.
  • . This has made the corporation an especially vulnerable target for the wave of compensatory litigation that began in earnest in the last three years and may last a generation. Tort lawsuits have become possible only in recent years, as scientists have begun more precisely to attribute regional effects to global emission levels. This is one subfield of climate science that has advanced significantly sin
  • Pomerance had not been among the 400 delegates invited to Noordwijk. But together with three young activists — Daniel Becker of the Sierra Club, Alden Meyer of the Union of Concerned Scientists and Stewart Boyle from Friends of the Earth — he had formed his own impromptu delegation. Their constituency, they liked to say, was the climate itself. Their mission was to pressure the delegates to include in the final conference statement, which would be used as the basis for a global treaty, the target proposed in Toronto: a 20 percent reduction of greenhouse-gas combustion by 2005. It was the only measure that mattered, the amount of emissions reductions, and the Toronto number was the strongest global target yet proposed.
  • The delegations would review the progress made by the I.P.C.C. and decide whether to endorse a framework for a global treaty. There was a general sense among the delegates that they would, at minimum, agree to the target proposed by the host, the Dutch environmental minister, more modest than the Toronto number: a freezing of greenhouse-gas emissions at 1990 levels by 2000. Some believed that if the meeting was a success, it would encourage the I.P.C.C. to accelerate its negotiations and reach a decision about a treaty sooner. But at the very least, the world’s environmental ministers should sign a statement endorsing a hard, binding target of emissions reductions. The mood among the delegates was electric, nearly giddy — after more than a decade of fruitless international meetings, they could finally sign an agreement that meant something.

Can the Paris Climate Goals Save Lives? Yes, a Lot of Them, Researchers Say - The New Y... - 0 views

  • The half-degree difference between 1.5 and two degrees may not seem like much, but, according to research published Wednesday in the journal Science Advances, it could mean saving or losing thousands of lives each year in the United States alone.
  • Dr. Lo and her colleagues used the 1.5 degree Celsius temperature target from the Paris Agreement as their baseline, and under that level of warming estimated the heat deaths that would occur in 15 cities across the United States. They selected those cities — which included Detroit, Los Angeles, Philadelphia and New York — because there was reliable climate and health data available.
  • “The numbers are quite astonishing in terms of how many deaths we could afford by limiting global warming to 1.5 degrees from three degrees,” Dr. Lo said. For example, she said, that would allow New York City to avoid 2,716 heat-related deaths during the most extreme temperature years
  • ...7 more annotations...
  • What they found is that, in almost every city they considered, the more global temperatures rose, the more people will die
  • There are some caveats. For example, as temperatures warm people tend to adapt
  • The 2003 heat wave in Europe is a good example. That year, an estimated 1,050 people died in London and Paris because of soaring temperatures
  • But in 2010, even though similar temperatures hit Europe, far fewer people in Western Europe died. (An estimated 56,000, however, died in Russia.)
  • “People become aware of the dangers,” Dr. Wehner said. “They changed their behaviors so that they were more likely to survive.”
  • A key form of adaptation is air-conditioning. But in cities like Seattle, where heat mortality is expected to increase, only a third of residents have air-conditioners. And air-conditioners pose their own problems both as contributors to climate change through energy consumption and because they pump warm air outside, further increasing urban temperatures
  • “The people that are at risk in cities are the very young, the very ill, and, generally, the poor,” Dr. Wehner said. “It’s people who don’t have access to air-conditioning.

Did Climate Change Happen Once Before In Earth's History? - The Atlantic - 0 views

  • the most striking feature of this early age of mammals is that it was almost unbelievably hot, so hot that around 50 million years ago there were crocodiles, palm trees, and sand tiger sharks in the Arctic Circle. On the other side of the blue-green orb, in waters that today would surround Antarctica, sea-surface temperatures might have topped an unthinkable 86 degrees Fahrenheit, with near-tropical forests on Antarctica itself. There were perhaps even sprawling, febrile dead zones spanning the tropics, too hot even for animal or plant life of any sort.
  • This is what you get in an ancient atmosphere with around 1,000 parts per million (ppm) of carbon dioxide. If this number sounds familiar, 1,000 ppm of CO2 is around what humanity is on pace to reach by the end of this century. That should be mildly concerning.
  • “You put more CO2 in the atmosphere and you get more warming, that’s just super-simple physics that we figured out in the 19th century,” says David Naafs, an organic geochemist at the University of Bristol. “But exactly how much it will warm by the end of the century, we don’t know. Based on our research of these ancient climates, though, it’s probably more than we thought.”
  • ...17 more annotations...
  • They were able to reverse engineer the ancient climate by analyzing temperature-sensitive structures of lipids produced by fossil bacteria and archaea living in these bygone wetlands, and preserved for all time in the coal. The team found that, under this past regime of high CO2, in the ancient U.K., Germany, and New Zealand, life endured mean annual temperatures of 23–29 degrees Celsius (73–84 degrees Fahrenheit) or 10–15 degrees Celsius (18–27 degrees Fahrenheit) warmer than modern times.
  • “These wetlands looked exactly how only tropical wetlands look at present, like the Everglades or the Amazon,” Naafs says. “So Europe would look like the Everglades and a heat wave like we’re currently experiencing in Europe would be completely normal. That is, it would be the everyday climate.”
  • But over 50 million years ago this would have been the baseline from about 45 to 60 degrees latitude. Under this broiling regime, with unprecedented heat as the norm, actual heat waves might have begun to take on an unearthly quality.
  • closer to the equator in this global sweat lodge, the heat might have been even more outrageous, shattering the limits of complex life. To see exactly how hot, Naafs’ team also analyzed ancient lignite samples from India, which would have been in the tropics at the time—that subcontinent still drifting across the Indian Ocean toward its eventual mountain-raising rendezvous with Asia. But unfortunately, the temperatures from these samples were maxed out. That is, they were too hot for his team to measure by the new methods they had developed.
  • “Some climate models suggest that the tropics just became a dead zone with temperatures over 50 degrees Celsius (122 degrees Fahrenheit) like in Africa and South America,” says Naafs. “But we have no data so we don’t know.”
  • “Basically every type of paleoclimate research that’s being done shows that high CO2 means that it’s very warm. And when it gets very warm, it can be really, really, really warm.
  • “You start really looking into them and you go, ‘Wow. We are dealing with a rainforest.’”
  • “You’ve got alligators, giant tortoises, primates, things like that. We have these big hippo-like animals called Coryphodon. You have tapirs—so you’ve got tapirs living pretty close to the North Pole in the early Eocene, which today—clearly tapirs are not at the North Pole,” she says, laughing.
  • One obvious way to reconcile this disparity is by noticing that the changes to the ancient earth took place over hundreds-of-thousands to millions of years and (IPCC graphs notwithstanding) that time won’t stop at the end of the 21st century. The changes that we’ve already set in motion, unless we act rapidly to countervail them, will similarly take millennia to fully unfold
  • we’re clearly not content to stop at just 400 ppm. If we do, in fact, push CO2 up to around 1,000 ppm by the end of the century, the warming will persist and the earth will continue to change for what, to humans, is a practical eternity
  • Most worryingly, the climate models that we depend on as a species to predict our future have largely failed to predict our sultry ancient past.
  • we know methane can actually amplify high-latitude warming, so maybe that’s some of the missing feedback.
  • Though there are no trees here at the top of the world, there are tree stumps. And they are around 50 million years old.
  • Clearly we are missing something, and Naafs thinks that one of the missing ingredients in the models is methane, a powerful greenhouse gas which might help close the divide between model worlds and fossil worlds.
  • We know tropical wetlands pump much more methane into the atmosphere compared to [cooler] wetlands.
  • The last time CO2 was at 400 ppm (as it is today) was 3 million years ago during the Pliocene epoch, when sea levels were perhaps 80 feet higher than today.
  • Naafs thinks that many of the wildest features of the early age of mammals could be recreated.

Major Trump administration climate report says damage is 'intensifying across the count... - 0 views

  • The National Climate Assessment’s publication marks the government’s fourth comprehensive look at climate-change impacts on the United States since 2000. The last came in 2014. Produced by 13 federal departments and agencies and overseen by the U.S. Global Change Research Program, the report stretches well over 1,000 pages and draws more definitive, and in some cases more startling, conclusions than earlier versions.
  • The authors argue that global warming “is transforming where and how we live and presents growing challenges to human health and quality of life, the economy, and the natural systems that support us.” And they conclude that humans must act aggressively to adapt to current impacts and mitigate future catastrophes “to avoid substantial damages to the U.S. economy, environment, and human health and well-being over the coming decades.”
  • “The impacts we’ve seen the last 15 years have continued to get stronger, and that will only continue,” said Gary Yohe, a professor of economics and environmental studies at Wesleyan University who served on a National Academy of Sciences panel that reviewed the report. “We have wasted 15 years of response time. If we waste another five years of response time, the story gets worse. The longer you wait, the faster you have to respond and the more expensive it will be.”

  • hat urgency is at odds with the stance of the Trump administration, which has rolled back several Obama-era environmental regulations and incentivized the production of fossil fuels. Trump also has said he plans to withdraw the nation from the Paris climate accord and questioned the science of climate change just last month, saying on CBS’s “60 Minutes” that “I don’t know that it’s man-made” and that the warming trend “could very well go back.”
  • “This report draws a direct connection between the warming atmosphere and the resulting changes that affect Americans' lives, communities, and livelihoods, now and in the future,” the document reads, concluding that “the evidence of human-caused climate change is overwhelming and continues to strengthen, that the impacts of climate change are intensifying across the country, and that climate-related threats to Americans' physical, social, and economic well-being are rising.
  • The report finds that the continental United States already is 1.8 degrees Fahrenheit warmer than it was 100 years ago, surrounded by seas that are on average nine inches higher and being racked by far worse heat waves than the nation experienced only 50 years ago. But those figures offer only the prelude to even more potentially severe impacts. The report suggests that by 2050, the country could see as much as 2.3 additional degrees of warming in the continental United States. By that same year, in a high-end global-warming scenario, coral reefs in Hawaii and the U.S. Pacific territories could be bleaching every single year — conditions in which their survival would be in severe doubt. A record-warm year like 2016 would become routine.
  • In another major step, the authors of the new report have begun to put dollar signs next to projected climate damage, specifically within the United States. In a worst-case climate-change scenario, the document finds, labor-related losses by the year 2090 as a result of extreme heat — the sort that makes it difficult to work outdoors or seriously lowers productivity — could amount to an estimated $155 billion annually. Deaths from temperature extremes could take an economic toll of $141 billion per year in the same year, while coastal property damage could total $118 billion yearly, researchers found
  • Of course, mitigating climate change would also mitigate this damage, by as much as 58 percent in the case of high-temperature related deaths, the report finds.
  • The categorical tone of the new assessments reflects scientists' growing confidence in the ability to detect the role of a changing climate in individual extreme events, such as heat waves and droughts. At the same time, increasingly sophisticated computer simulations now allow them to project future changes in highly specific regions of the country
  • The Second State of the Carbon Cycle Report, which examines all of North America (not just the United States), finds that over a decade, greenhouse-gas emissions from fossil fuels declined by 1 percent per year. The result is that while North America emitted 24 percent of the world’s emissions in 2004, that was down to 17 percent in 2013. This occurred in part thanks to improvements in vehicle fuel efficiency, the growth of renewable energy and the swapping of coal-burning for natural gas.
  • “For the globe, we’re still going up, but regionally, there have been these changes in how humans have been acting that have caused our emissions to go down,” said Ted Schuur, a Northern Arizona University expert on permafrost carbon
  • The report concludes that it appears possible to for economies to grow — at least in the United States, Mexico and Canada — without increasing overall emissions of greenhouse gases. That would be an important signal for the ability of the world to slow climate change over the course of the century

  • The 2019 extreme melt event is being compared to a record extreme heat and melt episode that occurred in Greenland in 2012. While the extent of surface melt during that event may have exceeded this one so far, Shuman found that Summit Station experienced warmth that was greater “in both magnitude and duration” during the current event
  • “The event itself was unusual that the warm air mass came from the east, and appears to be a part of the air mass that caused the record-breaking heat wave in Europe. Most of our extreme melt days on the Greenland ice sheet are associated with warm air masses moving from the west and south. I cannot recall an instance where we saw such extensive melt associated with an air mass coming from Northern Europe,”
  • The heat, along with below-average precipitation in parts of Greenland, has even sparked wildfires along the Greenland’s non-ice-covered western fringes. Satellite images and photos taken from the ground show fires burning in treeless areas, consuming mossy wetlands known as fen that can become vulnerable to fires when they dry out. These fires can burn into peatlands, releasing greenhouse gases buried long ago through decomposition of organic matter.
  • Studies have shown that ice melt periods like the one seen in 2012 typically occur about every 250 years, so the fact that another one is taking place only a few years later could be a sign of how climate change is upping the odds of such events
  • She said state-of-the-art climate computer models have been unable to simulate events like this, which hampers scientists’ ability to accurately predict Greenland ice melt and, therefore, future sea-level rise.

There remains much that can be done to limit the damage to come, to brace against the coming megafires and superstorms and save lives and hold onto a thriving civilization.
  • The effects of climate change evident today are the results of choices that countries made decades ago to keep pumping heat-trapping greenhouse gases into the atmosphere at ever-increasing rates despite warnings from scientists about the price to be paid.
  • Nations, including the United States, have dithered so long in cutting emissions that progressively more global warming is assured for decades to come, even if efforts to shift away from fossil fuels were accelerated tomorrow.
  • Things are on track to get “twice as bad” as they are now, he said, “if not worse.”
  • it may be time to flip that chronological framing, and consider today the new starting point.
  • “Don’t think of it as the warmest month of August in California in the last century,” he wrote. “Think of it as one of the coolest months of August in California in the next century.”
  • Their most sobering message was that the world still hasn’t seen the worst of it. Gone is the climate of yesteryear, and there’s no going back.
  • “It’s not that it’s out of our control. The whole thing is in our control.”
  • Managing climate change, experts said, will require rethinking virtually every aspect of daily life
  • how and where homes are built, how power grids are designed, how people plan for the future with the collective good in mind.
  • It will require an epochal shift in politics in a country that has, on the whole, ignored climate change
  • The fires, along with others in places including Colorado, Oregon and Washington, destroyed entire towns and sent smoke tens of thousands of feet high. San Francisco, Portland and Seattle have suffered some of the unhealthiest air quality on the planet, beating cities such as Beijing and New Delhi for the title. Smoke spread all the way across the continent, with particles coloring sunsets on the East Coast.
  • Evidence of global warming — which, scientists said, helps drive a rise in wildfire activity by creating hotter and drier conditions — was hanging visibly in the air.
  • For a long time, “there was so much focus on how climate change would affect the most vulnerable, like low-lying island nations or coral reefs — things that don’t dramatically affect the economic powerhouses of the world,”
  • “There’s often been this arrogant assumption that wealth provides protection.”
  • “we’re all in this together.”
  • First, experts broadly agreed, if we want to stop the planet from relentlessly heating up forever, humanity will quickly need to eliminate its emissions of planet-warming greenhouse gases.
  • every coal plant in China, every steel mill in Europe, every car and truck in the United States.
  • It’s a staggering task. It means reorienting a global economy that depends on fossil fuels
  • Even if we start radically slashing emissions today, it could be decades before those changes start to appreciably slow the rate at which Earth is warming. In the meantime, we’ll have to deal with effects that continue to worsen.
  • “Seriously, it is not reversible.”
  • Again and again, climate scientists have shown that our choices now range from merely awful to incomprehensibly horrible.
  • If we cut emissions rapidly, about one-seventh of the world’s population will suffer severe heat waves every few years.
  • Failure to do so doubles or triples that number.
  • If we act now, sea levels could rise another 1 to 2 feet this century.
  • If we don’t, Antarctica’s ice sheets could destabilize irreversibly and ocean levels could keep rising at an inexorable pace for centuries, making coastal civilization all but unmanageable.
  • The best hope is to slow the pace of warming enough to maintain some control for humanity.
  • “In our research, we’ve found that most systems can cope with a 1.5-degree or 2-degree world, although it will be very costly and extremely difficult to adapt
  • “But in a 4-degree world, in many cases, the system just doesn’t work anymore.”
  • So, even as nations cut emissions, they will need to accelerate efforts to adapt to the climate change they can no longer avoid.
  • “The human capacity for adaptation is extraordinary — not unlimited, but extraordinary,”
  • “I’m much more concerned for the future of the nonhuman than I am for the future of humans, precisely because we’re just very, very good at adaptation.”
  • adaptation is usually a reactive measure, not a preventive one
  • Adapting to climate change means envisioning bigger disasters to come — again, flipping the framing away from history and into the future.
  • “Humans have difficulty imagining things that we haven’t experienced yet,”
  • It’s hard to visualize the entire West Coast aflame until you actually see it. And if we can’t see it, we tend to discount the risk.”
  • And there’s the moral hazard problem, which is when people are shielded from the costs of their decisions and thus make bad ones.
  • Cascading Disasters
  • Adaptation can quickly become bogged down in a tangle of competing motivations and unintended consequences.
  • Proposals for stricter building codes or higher insurance premiums face opposition from builders and voters alike.
  • Whether Americans can adopt that mentality remains an open question.“We’ve often heard the argument that it will be too expensive to cut emissions and it will just be easier to adapt,” said Noah Diffenbaugh, a climate scientist at Stanford University. But we’ve now had decades of warnings, he said, “and we’re not even adapted to the present climate.”
  • as climate change intensifies, it increases the risk of “compound hazards,” when numerous disasters strike simultaneously, as well as the risk that one disaster cascades into another.
  • Experts also noted that climate change is an accelerant of inequality. Those most affected, globally and in the United States, tend to be the most vulnerable populations.
  • One concern is that adaptability will not be a collective effort. Wealthier people may find ways to protect themselves, while others are left fending for themselves
  • A Lifetime of Clues
  • For well over a century, science has provided us with powerful clues that this was coming.
  • As early as the 1850s, researchers realized that greenhouse gases like carbon dioxide could trap heat on Earth. This came at the dawn of the Industrial Age,
  • “I feel like the climate scientists have kind of done our job,” said Dr. Kalmus, the Los Angeles-based scientist. “We’ve laid it out pretty clearly, but nobody’s doing anything. So now it’s kind of up to the social scientists.”
  • ne 2017 study found that people who experience extreme weather are more likely to support climate adaptation measures than before. But the effect diminished over time. It may be that people mentally adjust to unusual weather patterns, updating their perception of what they consider normal.
  • “There’s too much complexity and, frankly, too much that needs to be changed, that we’re flitting from one concern to another,”
  • “What’s beautiful about the human species is that we have the free will to decide our own fate,” said Ilona Otto, a climate scientist at the Wegener Center for Climate and Global Change. “We have the agency to take courageous decisions and do what’s needed,” she said. “If we choose.”

Ocean Currents in the Atlantic Could Slow by Century's End, Research Shows - The New Yo... - 0 views

  • The last time there was a major slowdown in the mighty network of ocean currents that shapes the climate around the North Atlantic, it seems to have plunged Europe into a deep cold for over a millennium.
  • That was roughly 12,800 years ago, when not many people were around to experience it. But in recent decades, human-driven warming could be causing the currents to slow once more, and scientists have been working to determine whether and when they might undergo another great weakening, which would have ripple effects for weather patterns across a swath of the globe.
  • A pair of researchers in Denmark this week put forth a bold answer: A sharp weakening of the currents, or even a shutdown, could be upon us by century’s end.
  • ...21 more annotations...
  • Climate scientists generally agree that the Atlantic circulation will decline this century, but there’s no consensus on whether it will stall out before 2100.
  • the new findings were reason enough not to regard a shutdown as an abstract, far-off concern. “It’s now,” she said.
  • As humans warm the atmosphere, however, the melting of the Greenland ice sheet is adding large amounts of fresh water to the North Atlantic, which could be disrupting the balance of heat and salinity that keeps the overturning moving. A patch of the Atlantic south of Greenland has cooled conspicuously in recent years, creating a “cold blob” that some scientists see as a sign that the system is slowing.
  • Abrupt thawing of the Arctic permafrost. Loss of the Amazon rain forest. Collapse of the Greenland and West Antarctic ice sheets. Once the world warms past a certain point, these and other events could be set into swift motion, scientists warn, though the exact thresholds at which this would occur are still highly uncertain.
  • In the Atlantic, researchers have been searching for harbingers of tipping-point-like change in a tangle of ocean currents that goes by an unlovely name: the Atlantic Meridional Overturning Circulation, or AMOC (pronounced “AY-mock”).
  • These currents carry warm waters from the tropics through the Gulf Stream, past the southeastern United States, before bending toward northern Europe. When this water releases its heat into the air farther north, it becomes colder and denser, causing it to sink to the deep ocean and move back toward the Equator. This sinking effect, or “overturning,” allows the currents to transfer enormous amounts of heat around the planet, making them hugely influential for the climate around the Atlantic and beyond.
  • adds to a growing body of scientific work that describes how humankind’s continued emissions of heat-trapping gases could set off climate “tipping points,” or rapid and hard-to-reverse changes in the environment.
  • Much of the Northern Hemisphere could cool. The coastlines of North America and Europe could see faster sea-level rise. Northern Europe could experience stormier winters, while the Sahel in Africa and the monsoon regions of Asia would most likely get less rain.
  • Scientists’ uncertainty about the timing of an AMOC collapse shouldn’t be taken as an excuse for not reducing greenhouse-gas emissions to try to avoid it, said Hali Kilbourne, an associate research professor at the University of Maryland Center for Environmental Science.
  • scientists’ most advanced computer models of the global climate have produced a wide range of predictions for how the currents might behave in the coming decades, in part because the mix of factors that shape them is so complex.
  • Dr. Ditlevsen’s new analysis focused on a simple metric, based on sea-surface temperatures, that is similar to ones other scientists have used as proxies for the strength of the Atlantic circulation. She conducted the analysis with Peter Ditlevsen, her brother, who is a climate scientist at the University of Copenhagen’s Niels Bohr Institute. They used data on their proxy measure from 1870 to 2020 to calculate statistical indicators that presage changes in the overturning.
  • “Not only do we see an increase in these indicators,” Peter Ditlevsen said, “but we see an increase which is consistent with this approaching a tipping point.”
  • They then used the mathematical properties of a tipping-point-like system to extrapolate from these trends. That led them to predict that the Atlantic circulation could collapse around midcentury, though it could potentially occur as soon as 2025 and as late as 2095.
  • Their analysis included no specific assumptions about how much greenhouse-gas emissions will rise in this century. It assumed only that the forces bringing about an AMOC collapse would continue at an unchanging pace — essentially, that atmospheric carbon dioxide concentrations would keep rising as they have since the Industrial Revolution.
  • they voiced reservations about some of its methods, and said more work was still needed to nail down the timing with greater certainty.
  • Susan Lozier, a physical oceanographer at Georgia Tech, said sea-surface temperatures in the North Atlantic near Greenland weren’t necessarily influenced by changes in the overturning alone, making them a questionable proxy for inferring those changes. She pointed to a study published last year showing that much of the cold blob’s development could be explained by shifts in wind and atmospheric patterns.
  • Scientists are now using sensors slung across the Atlantic to directly measure the overturning. Dr. Lozier is involved in one of these measurement efforts. The aim is to better understand what’s driving the changes beneath the waves, and to improve projections of future changes.
  • Still, the new study sent an urgent message about the need to keep collecting data on the changing ocean currents,
  • Were the circulation to tip into a much weaker state, the effects on the climate would be far-reaching, though scientists are still examining their potential magnitude.
  • “It is very plausible that we’ve fallen off a cliff already and don’t know it,” Dr. Kilbourne said. “I fear, honestly, that by the time any of this is settled science, it’s way too late to act.”
  • the projects began collecting data in 2004 at the earliest, which isn’t enough time to draw firm long-term conclusions. “It is extremely difficult to look at a short record for the ocean overturning and say what it is going to do over 30, 40 or 50 years,”

Climate Change Obsession Is a Real Mental Disorder - WSJ - 0 views

  • If heat waves were as deadly as the press proclaims, Homo sapiens couldn’t have survived thousands of years without air conditioning. Yet here we are
  • Humans have shown remarkable resilience and adaptation—at least until modern times, when half of society lost its cool over climate change.
  • it’s alarmist stories about bad weather that are fueling mental derangements worthy of the DSM-5—not the warm summer air itself.
  • ...15 more annotations...
  • The Bloomberg article cites a July meta-analysis in the medical journal Lancet, which found a tenuous link between higher temperatures and suicides and mental illness. But the study deems the collective evidence of “low certainty” owing to inconsistent study findings, methodologies, measured variables and definitions.
  • “climate change might not necessarily increase mental health issues because people might adapt over time, meaning that higher temperatures could become normal and not be experienced as anomalous or extreme.”
  • yes. Before the media began reporting on putative temperature records—the scientific evidence for which is also weak—heat waves were treated as a normal part of summer. Uncomfortable, but figuratively nothing to sweat about.
  • according to a World Health Organization report last year, the very “awareness of climate change and extreme weather events and their impacts” may lead to a host of ills, including strained social relationships, anxiety, depression, intimate-partner violence, helplessness, suicidal behavior and alcohol and substance abuse.
  • A study in 2021 of 16- to 25-year-olds in 10 countries including the U.S. reported that 59% were very or extremely worried about climate change, and 84% were at least moderately worried
  • Forty-five percent claimed they were so worried that they struggled to function on a daily basis, the definition of an anxiety disorder.
  • “First and foremost, it is imperative that adults understand that youth climate anxiety (also referred to as eco-anxiety, solastalgia, eco-guilt or ecological grief) is an emotionally and cognitively functional response to real existential threats,” a May 10 editorial in the journal Nature explained. “Although feelings of powerlessness, grief and fear can be profoundly disruptive—particularly for young people unaccustomed to the depth and complexity of such feelings—it is important to acknowledge that this response is a rational one.”
  • These anxieties are no more rational than the threats from climate change are existential.
  • A more apt term for such fear is climate hypochondria.
  • The New Yorker magazine earlier this month published a 4,400-word piece titled “What to Do With Climate Emotions” by Jia Tolentino, a woman in the throes of such neurosis
  • Ms. Tolentino goes on to describe how climate therapists can help patients cope. “The goal is not to resolve the intrusive feeling and put it away” but, as one therapist advises her, “to aim for a middle ground of sustainable distress.” Even the climate left’s despair must be “sustainable.”
  • there’s nothing normal about climate anxiety, despite the left’s claims to the contrary.
  • Progressives may even use climate change to displace their other anxieties—for instance, about having children
  • Displacement is a maladaptive mechanism by which people redirect negative emotions from one thing to another
  • Climate hypochondriacs deserve to be treated with compassion, much like anyone who suffers from mental illness. They shouldn’t, however, expect everyone else to enable their neuroses.

Climate Change Made Europe's Mega-Heatwave Five Times More Likely - Scientific American - 0 views

  • climate change made the temperatures reached in France last week at least five times more likely to occur than in a world without global warming
  • The scientists with the World Weather Attribution Project decided to take action when they saw the heatwave coming and ended up performing a real-time analysis while at a climate conference in Toulouse, France
  • “We discussed our approach and gathered data and looked at climate models between talks,”
  • ...6 more annotations...
  • To find out whether global warming has affected the likelihood of a real-life event, scientists look at existing weather records and compare them with models, including simulations of how the weather would behave in a world that isn’t warming. The concept has matured since it was conceived more than a decade ago, but it is necessarily probabilistic by nature
  • “Some say the uncertainties are too big,” says Otto. “There are indeed caveats, mostly to do with imperfect climate models. But even with large uncertainty bars we think it is useful to provide quantitative evidence for how climate change is affecting extreme weather,”
  • But in a second analysis that looked at historical temperature records over the past century rather than models, the team calculated that the likelihood of such a heatwave in June has in fact increased 100 times since around 1900, owing to the combined influence of climate change and other factors such as air pollution
  • The probability calculated by the models is likely to be an underestimate, say the researchers. That’s because unlike the real-world data, the simulations consider only climate-related factors, and don’t represent aspects such as changes in cloud cover, land use, irrigation and air pollution, which all seem to have an influence on temperature
  • “Climate models are missing something when it comes to capture fairly short-lived heat events,”
  • To date, more than 200 attribution studies have examined whether climate change made particular events — including heat spells, droughts, floods and storms — more likely. Researchers found that about two-thirds of the extreme events they analysed were made more likely, or more severe, by the build-up of greenhouse-gases in the atmosphere.

Opinion | Biden and Climate Change Have Reshaped the Middle East - The New York Times - 0 views

  • omething is in the air that is powerfully resetting the pieces on the Middle East chess board — pieces that had been frozen in place for years. The biggest force shifting them was Biden’s decision to pull out of Afghanistan and tell the region: “You’re home alone. If you’re looking for us, we’ll be in the Straits of Taiwan. Write often. Send oil. Bye.”
  • a second factor is intensifying the pressure of America’s leaving: Mother Nature, manifesting herself in heat waves, droughts, demographic stresses, long-term falling oil prices and rising Covid-19 cases.
  • this shift will force every leader to focus more on building ecological resilience to gain legitimacy instead of gaining it through resistance to enemies near and far.
  • ...12 more annotations...
  • we are firmly in a transition from a Middle East shaped by great powers to a Middle East shaped by Mother Nature.
  • “The U.S. is not pulling out entirely, but it is pulling back, and all of its Sunni Arab partners are now acting to protect themselves — and to stabilize the region — in an era when the U.S. will no longer be dominant there,”
  • et’s go back to Biden. He was dead right: America’s presence in Afghanistan and tacit security guarantees around the region were both stabilizing and enabling a lot of bad behavior — boycotts, occupations, reckless adventures and brutal interventions.
  • President Barack Obama’s pullback from the region and President Donald Trump’s refusal to retaliate against Iran — after it sent a wave of drones to attack a key Saudi oil facility in 2019 — were the warning signs that America had grown weary of intervening and refereeing in the Middle East’s sectarian wars. Biden just made it official.
  • We are just at the start of this paradigm shift from resistance to resilience, as this region starts to become too hot, too populated and too water-starved to sustain any quality of life.
  • “But the U.S. will still be needed to deter Iran, should it develop a nuclear capability — and to defuse other conflicts.”
  • just as we once supplanted the Soviets as the dominant shaper in the region, Mother Nature is now supplanting America as the dominant force.
  • In Mother Nature’s Middle East, leaders will be judged not by how much they resist one another or great powers, but by how much resilience they build for their people and nations at a time when the world will be phasing out fossil fuels, at a time when all the Arab-Muslim states have booming populations under the age of 30 and at a time of intensifying climate change.
  • The United Nations recently reported that Afghanistan has been hit with the worst drought in more than 30 years. It is crushing farmers, pushing up food prices and putting 18.8 million Afghans — nearly half of the population — into food insecurity. Over to you, Mr. Taliban: You broke it, you own it.
  • there may be a day, very soon, where the United States will need to return to active Israeli-Palestinian diplomacy — not based on land for peace, but sun and fresh water for peace. EcoPeace Middle East, an alliance of Israeli, Palestinian and Jordanian environmentalists, recently put forward just such a strategy called the “Green Blue Deal.”
  • How would it work? Jordan, with its vast desert areas, has the comparative advantage to produce large amounts of cheap solar electricity to meet its own needs and also to sell to the Israeli and Palestinian grids to “generate the electricity for desalination plants that could provide all three parties abundant fresh water,”
  • All the parties there are ecologically interdependent, but they have unhealthy interdependencies rather than healthy ones. America could become the trusted mediator who forges healthy interdependencies
