On Friday, those figures had passed 45 million cases and more than 1.1 million deaths, according to Johns Hopkins University.

Taiwan's landmark achievement comes in a week when France and Germany are enacting new lockdowns and the United States identified a record 88,000-plus cases in a day. The state of Florida, which has a similar population size to Taiwan, with approximately 21 million people, identified 4,188 cases on Wednesday alone.

Taiwan's response focused on speed. Taiwanese authorities began screening passengers on direct flights from Wuhan, where the virus was first identified, on December 31, 2019 -- back when the virus was mostly the subject of rumors and limited reporting.

Taiwan confirmed its first reported case of the novel coronavirus on January 21 and then banned Wuhan residents from traveling to the island. All passengers arriving from mainland China, Hong Kong and Macao were required to undergo screening.

All this happened before Wuhan itself went into lockdown on January 23.

By March, Taiwan banned all foreign nationals from entering the island, apart from diplomats, residents and those with special entry visas.

One is geography -- Taiwan is an island, so it's easier for officials to control entry and exit through its borders.

Taiwan also had experience on its side. After suffering through the deadly outbreak of severe acute respiratory syndrome (SARS) in 2003, Taiwan worked to build up its capacity to deal with a pandemic

Authorities activated the island's Central Epidemic Command Center, which was set up in the wake of SARS, to coordinate between different ministries. The government also ramped up face mask and protective equipment production to make sure there would be a steady supply of PPE.

The government also invested in mass testing and quick and effective contact tracing.

"Very careful contact tracing, and very stringent quarantines of close contacts are the best way to contain Covid-19," he said.

Johnson, however, noted the onus is not on the family to pursue charges. It is up to District Attorney Larry Krasner. The family does intend to file a wrongful death suit.

The attorney described the final moments of Wallace's life as they were captured in the body cam footage, saying the officers made no attempt to diffuse the chaotic situation upon their arrival. On the contrary, he said, it was clear the officers intended to kill the mentally unstable man.

According to the family, they called 911 to summon an ambulance that would help them calm Wallace who was experiencing a psychological episode. But instead of healthcare professionals trained to handle such situations it was the two officers who showed up.

Johnson said he looked like a person in "obvious mental health crisis." "You will see a person walking around not even speaking," said Johnson, remarking that it looked as if Wallace was "in a cloud."

"I understand he had a knife ... and I think that does not give you carte blanche to execute a man," he said.

Wallace was approximately a car and a half-length away.

Johnson also claims the video shows Wallace was incapacitated after the first shot.

The video captures audio of one officer telling the other to "shoot him" before both opened fire, Johnson said.

The officers involved in the shooting claim Wallace advanced toward them with the knife but the family disputes that account. Several videos recorded by bystanders show at least one officer shouted for Wallace to put down the weapon.

The officers' names have not been released. Both have been suspended from active patrol and remain on desk duty.

Police Commissioner Danielle Outlaw has pledged to release the video and audio tapes.

Mayor Jim Kenney and District Attorney Larry Krasner released a joint statement Thursday night saying the footage and 911 audio files will be released by the end of next week.

Lankford noted that after the 9/11 terrorist attacks, the bipartisan committee that investigated them found that the compressed time frame for the transition after the contested 2000 election may have contributed to the lack of preparedness for the attack.

In their report after the attacks, the commission said that the dispute over the election and the "36-day legal fight" following "cut in half the normal transition period." The loss of time, the commission said, "hampered the new administration in identifying, recruiting, clearing, and obtaining Senate confirmation of key appointees,"

The intermediary step by Republicans in the President's orbit illuminated the widening divide between the practical reality that Biden must be equipped with key national security knowledge to begin running the country in January and the political fiction being perpetrated by the President and his supporters.

Ohio's Republican Gov. Mike DeWine, who heads a state the President won last week, said on CNN's "New Day" that "we need to consider the former vice president as the President-elect."

Trump has showed little interest in addressing the most important issue facing the country: the record-breaking climb in US coronavirus cases.

The illusory quality of Trump's election fraud claims was once again underscored by a set of election integrity checks that are being conducted in Arizona, which CNN called for Biden late Thursday night.

post-election audits filed with the Arizona Secretary of State's office from more than half of Arizona's counties showed that there is no evidence of systematic voter fraud or major discrepancies that would affect the outcome of the race.

A group of national, state and private election officials said in a joint statement Thursday that there is no evidence that "any voting system deleted or lost votes, changed votes, or was in any way compromised."

"The November 3rd election was the most secure in American history. Right now, across the country, election officials are reviewing and double checking the entire election process prior to finalizing the result," the Election Infrastructure Government Coordinating Council and the Election Infrastructure Sector Coordinating Executive Committees said.

The most surreal feature of the suspended reality at the White House is still the behavior of the President himself. A leader who jealously dominated television coverage on the campaign trail and in office has not made public remarks for an entire week

"I'm worried about this virus, I'm not looking at what the merits of the case are. It would appear that Joe Biden is going to be the next president of the United States," DeWine said, adding that America needs to "come together as a country."

But the President's Twitter feed Thursday indicated that he was much more fixated on what he views as his mistreatment by Fox News, his once favored network, which he believes should be defending him more vociferously in the midst of the twilight zone that he has created by refusing to acknowledge Biden's victory.

The President, whom CNN quoted sources as describing as increasingly "dejected" on Thursday, continues to tweet falsehoods about election fraud.

there are few signs that his campaign has convinced any court to take his complaints seriously. In this odd limbo between defiance and admitting defeat, the President is wavering between fighting on and a recognition that his hold on power is coming to an end,

While his adult sons, Donald Trump Jr. and Eric Trump, have urged their father to continue challenging the election results, his daughter Ivanka Trump and her husband Jared Kushner have taken a more measured approach, CNN reported Thursday, encouraging the President to think about potential damage to his legacy as they weigh their own post-White House ambitions.

In addition to Biden's win in Arizona, the President trails in Georgia, where a hand recount is beginning, by 14,000 votes -- a cushion for Biden unlikely to be overturned.

Meanwhile, Biden's political choreography -- which late Wednesday included the naming of Ron Klain as his White House chief of staff -- and his departure to his family beach house to decompress after the election is meant to signal that his ascent to power is assured.

In what may have been a signal to establishment Republicans -- in a venue that the President himself might take account of -- former George W. Bush strategist Karl Rove wrote in a Wall Street journal op-ed that the election will not be overturned whatever the result of Trump's legal gambits.

Lankford, who referred to Biden as President-elect at his church last week, has said he will intervene if the victorious Democrat remains unable to access intelligence briefings.

"I've been a little concerned about it," Senate Armed Services Chairman Jim Inhofe said of the Pentagon firings, adding he'd been told "now it's come to an end."

As Republican lawmakers stake out safe ground -- trying to appear that they are still supporting the President's legal pursuits while also signaling that the transition should begin -- some Democrats have been hammering their GOP colleagues for indulging the President's election fantasies.

"These Republicans are all auditioning for profiles in cowardice," Schumer said.

On Thursday, the US broke the record for Covid-19 hospitalizations for the third consecutive day, surpassing 67,000 hospitalizations.

The glimmer of hope on the horizon continued to be Pfizer's promising announcement earlier this week that their vaccine trial is more than 90% effective with officials widely expecting that the company will apply for emergency use authorization from the US Food and Drug Administration before the end of this month.

"By the end of March to early April, we think across all of the vaccines that we have invested in, we have enough for all Americans who wish to get vaccinated," Azar said.

"If you think of it metaphorically, you know, the cavalry is coming here," Fauci said, touting the major positive impact that the vaccines will have."If we could just hang in there, do the public health measures that we're talking about," Fauci said. "We're going to get this under control, I promise you."

President-elect Joe Biden's team has magnified the giant hurdles that loom for government officials as they try to ensure the smooth delivery of millions of vaccine doses within the 50 states and cities with different ideas about the best way to administer them.

Trump told guests that with the help of "certain very important people -- if they have wisdom and if they have courage -- we're going to win this election." The crowd chanted "four more years."

the crucial question is whether Trump and his administration are equipping the incoming Biden administration with the knowledge and tools they need to carry out an unprecedented vaccination operation as Trump's White House grudgingly passes the baton.

Trump is pursuing a new round in his quixotic bid to overturn the November election by attempting to intervene in a lawsuit filed with the Supreme Court.

There were signs Wednesday, however, that cooperation is slowly beginning to take shape behind the scenes. Health and Human Services Secretary Alex Azar said that he has met with Biden's team -- a rare acknowledgment of the former vice president's victory from a top Trump official -- and he insisted that he wants "to make sure they get everything that they need."

"Twenty million people should get vaccinated in just the next several weeks, and then we'll just keep rolling out vaccines through January, February, March as they come off the production lines," Azar said, trying to offer a note of reassurance about continuity during an interview on CNN's New Day.

The vaccine distribution challenges surrounding a once-in-a-lifetime pandemic would normally be at the top of the agenda for any commander-in-chief. But unsurprisingly, Trump is refusing to acknowledge the potential problems as he spreads disinformation to his supporters, and his administration -- at his behest -- continues to target Biden's son Hunter, who revealed Wednesday that his taxes are under federal investigation.

"Unless a court makes some other decision, the Electoral College is the defining outcome of the presidential race," Moran said. Asked what would be next if Trump doesn't concede, Moran said: "There is a transition that just occurs -- occurs under our laws under the Constitution."

Kansas Sen. Jerry Moran, a Republican, said "it is unhealthy for the well-being of the country" to continue debating the outcome of the election "once the presidential race has been determined."

The attorney representing Trump, John Eastman, is known for recently pushing a racist conspiracy theory -- that Trump himself later amplified -- claiming Vice President-elect Kamala Harris might not be eligible for the role because her parents were immigrants.

With hopes riding on the vaccine authorization discussion Thursday, the country continued to grapple with an alarming rise in cases around the country as medical professionals began to see the post-Thanksgiving spike materialize and some regions reverted to shutdowns to try to preserve hospital capacity.

"This is by far, the worst surge to date," Colfax said. "The reality is unfortunately proving to be as harsh as we expected. ... The vaccine will not save us from this current surge -- there is simply not enough time."

"The more terrible truth is that over 8,000 people, ... who were beloved members of their family, are not coming back. And their deaths are an incalculable loss to their friends and their family, as well as our community."

Though Trump has said that the vaccination program will "quickly and dramatically reduce deaths," a new White House task force report warns that the vaccine "will not substantially reduce viral spread, hospitalizations, or fatalities until the 100 million Americans with comorbidities can be fully immunized, which will take until the late spring."

The FDA is expected to conduct its authorization review between December 11 and the 14, with first shipment of the vaccine going out by December 15. Needles, syringes and other materials to deliver the vaccines are already on their way to states.

Gen. Gustave Perna, said that 2.9 million doses of vaccine will go out in the first shipment from Pfizer once the FDA grants emergency use authorization.

Initially the federal government expected to receive 6.4 million doses from Pfizer as the first shipment. But because the vaccine is administered in two doses, the math is more complicated. About 500,000 doses will be set aside as a reserve supply, and the remaining number was divided in half to set aside what is needed for the second dose of the Pfizer vaccine, which brought down the total in the first shipment to 2.9 million doses.

"We just want to make sure that Americans understand exactly the science that went into this, understand the gold standard of the FDA and the approval process. We want to make sure that the vaccines are actually administered, and we're afraid that that won't happen," Ostrowski said.

Professional associations like the American Geriatrics Society and advocacy groups like Justice in Aging have focused more on the opposite possibility: They want to prevent older and disabled people from being arbitrarily sent to the rear of the line.

Some policies adopted by states or health care systems to allocate medical resources — equipment, drugs, critical care and intensive-care beds — specifically make age part of the equation.

In March, the Office of Civil Rights reaffirmed that the Affordable Care Act and other federal statutes prohibit discrimination, in health facilities receiving federal funds, on the basis of age, disability and other characteristics.

“It’s akin to the person who runs into a burning building or gives up the last seat on the lifeboat,” said Dr. Andrea Kittrell, an otolaryngologist in Lynchburg, Va., who created the organization in March. “There are those people who are selfless and generous and value other people’s lives as much or more than their own.”

Successful programs like Experience Corps also point to a common criticism of the fair innings philosophy: The last innings of the game can be among the most significant.

as the production of food and material goods centralized and rapidly expanded, commerce reached a scale that the country’s existing stores were ill-equipped to handle, according to the historian Susan Strasser, the author of Satisfaction Guaranteed: The Making of the American Mass Market. Manufacturers needed ways to distribute their newly enormous outputs and educate the public on the wonder of all their novel options. Americans, in short, had to be taught how to shop.

In 2019, one in five American workers was employed in retail, food service, or hospitality; even more are now engaged in service work of some kind.

This dynamic is exacerbated by the fact that the United States has more service workers than ever before, doing more types of labor, spread thin across the economy

Customers might not have been able to afford a household staff to do their bidding like the era’s truly wealthy, but corporate stores offered them a little taste of what that would be like. The middle class began to see itself as the small-time beneficiaries of industrialization’s barons.

With these goals in mind, Leach writes, customer service was born. For retailers’ tactics to be successful, consumers—or guests, as department stores of the era took to calling them—needed to feel appreciated and rewarded

From 1870 to 1910, the number of service workers in the United States quintupled. It’s from this morass that “The customer is always right” emerged as the essential precept of American consumerism—service workers weren’t there just to ring up orders

they were there to fuss and fawn, to bolster egos, to reassure wavering buyers, to make dreams come true.

they were also quite intentionally building something far grander: class consciousness. Leach writes that the introduction of shopping was fundamental to forming middle-class identity at a particularly crucial moment, as the technological advances of the Gilded Age helped create the American office worker as we now know it.

Retailers won over this growing middle class by convincing its members that they were separate from—and opposed to—industrial workers and their distrust of corporate power,

For many of these workers, the difficulty of finding non-service employment enables companies to pay low wages and keep their prices artificially low, which consumers generally like as long as they don’t have to think about what makes it possible. In theory, these conditions are supposed to encourage better performance on the part of the worker; in practice, they also encourage cruelty on the part of the consumer.

Previously confined to a few lavish European-owned hotels in America, tipping “aristocratized consumption,

Department-store magnates alleviated these concerns by linking department stores to the public good. Retailers started inserting themselves into these communities as much as possible, Leach writes, turning their enormous stores into domains of urban civic life. They hosted free concerts and theatrical performances, offered free child care, displayed fine art, and housed restaurants, tearooms, Turkish baths, medical and dental services, banks, and post offices. They made splashy contributions to local charities and put on holiday parades and fireworks shows. This created the impression that patronizing their stores wouldn’t just be a practical transaction or an individual pleasure, but an act of benevolence toward the orderly society those stores supported.

In the 150 years that American consumerism has existed, it has metastasized into almost every way that Americans construct their identities. Today’s brands insert themselves into current events, align themselves with causes, associate patronage of their businesses with virtue and discernment and success.

Most Americans now expect corporations to take a stand on contentious social and political issues; in return, corporations have even co-opted some of the language of actual politics, encouraging consumers to “vote with their dollars” for the companies that market themselves on the values closest to their own.

For Americans in a socially isolating culture, living under an all but broken political system, the consumer realm is the place where many people can most consistently feel as though they are asserting their agency.

Being corrected by a salesperson, forgotten by a bartender, or brushed off by a flight attendant isn’t just an annoyance—for many people, it is an existential threat to their self-understanding.

“The notion that at the restaurant, you’re better than the waiters, it becomes part of the restaurant experience,” and also part of how some patrons understand their place in the world. Compounding this sense of superiority is the fact that so many service workers are from historically marginalized groups—the workforce is disproportionately nonwhite and female.

Because consumer identities are constructed by external forces, Strasser said, they are uniquely vulnerable, and the people who hold them are uniquely insecure

If your self-perception is predicated on how you spend your money, then you have to keep spending it, especially if your overall class status has become precarious, as it has for millions of middle-class people in the past few decades

Although underpaid, poorly treated service workers certainly exist around the world, American expectations on their behavior are particularly extreme and widespread, according to Nancy Wong, a consumer psychologist and the chair of the consumer-science department at the University of Wisconsin. “Business is at fault here,” Wong told me. “This whole industry has profited from exploitation of a class of workers that clearly should not be sustainable.”

Tipping ratcheted up the level of control that members of the middle class could exercise over the service workers beneath them: Consumers could deny payment—effectively, deny workers their wages—for anything less than complete submission.

Modern businesses have invented novel ways to exacerbate conflicts between their customers and their workers.

A big problem at airlines and hotels in particular, Wong said, is what’s called the “customer relationship management” model. CRM programs, the first and most famous of which are frequent-flyer miles, are fabulously profitable; awarding points or miles or bucks encourages people not only to increase the size and frequency of their purchases, but also to confine their spending to one airline or hotel chain or big-box store.

Higher-spending customers access varying levels of luxury and prestige, often in full view of everyone else. Exposure to these consumer inequalities has been found to spark antisocial behavior in those who don’t get to enjoy their perks, the classic example of which is air rage

Workers must do what the sociologist Arlie Russell Hochschild, in her 1983 book, The Managed Heart, identified as “emotional labor.”

Workers must stifle their natural emotional reactions to, in the case of those in the service industry, placate members of the consumer class. These workers are alienated from their own emotional well-being, which can have far-reaching psychological consequences—over the years, research has associated this kind of work with elevated levels of stress hormones, burnout, depression, and increased alcohol consumption.

Never mind that Trump had drawn down U.S. troop levels from about 13,000 to 2,500 during his last year in office and had failed to repatriate America’s equipment on the ground. Never mind the delay caused by Trump and his adviser Stephen Miller’s active obstruction of special visas for Afghans who helped us.

Rather than view the heartbreaking scenes in Afghanistan in a political light as his opponents did, Biden effectively said, “Politics be damned—we’re going to do what’s right” and ordered his team to stick with the deadline and find a way to make the best of the difficult situation in Kabul.

Despite years of fighting, the administration and the military spoke with the Taliban many times to coordinate passage of those seeking to depart to the airport, to mitigate risks as best as possible, to discuss their shared interest in meeting the August 31 deadline.

Not only is the process still prohibitively expensive, research has shown that so far it hasn’t been very effective. A 2019 study at Stanford University found that current carbon capture projects miss well more than half of the carbon dioxide in emissions.

Project Tundra’s managers hope they can achieve a significant breakthrough, aiming to capture 90 percent of the CO2 once they have the project in operation. Essentially, the carbon dioxide would be absorbed out of the “flue gas,” or exhaust, by amine-based solvents, which would be pumped to a regeneration unit that would heat the solvents and free the CO2 again, in a pure form. Then it would be condensed and pumped to natural caverns deep underground.

For now the project is still in the design and engineering phase, together with financial analysis. Equipment at the site has been used to test the process; now the results are being analyzed. If the pieces fall into place and the project gets a green light from regulators and company officials, construction could get started as early as next year.

“This carbon sequestration project really gets us excited,” he said. “It gives coal a role in stabilizing the grid.” He added: “If there are better solutions than coal out there, so be it. We just believe those solutions don’t exist.”

There are warning signs, nonetheless. Even though the price of oil has bounced back after the disastrous months when the pandemic struck last year, and production at existing wells is humming along, there’s little new drilling in the Bakken. The number of rigs has fallen from 55 in early 2020 to 23 today.

Her attitude about the coal-powered electricity she uses in her car is that it’s not great, it’s probably on the way out, it’s better than using gasoline.“Gas is a continuous circle of energy wastage,” she said. “You have to use energy to extract it, you have to use energy to transport it, you have to use energy to refine it, you have to use energy to transport it back.

Kathy Neset moved to the Bakken with a degree in geology from Brown University in 1979 and built a successful oil-field consulting company on the vast, windswept jumble of low hills and ridges, once good only for cattle raising. She understands perfectly well that electric cars are coming, yet she has faith that new uses for petroleum will keep the oil sector in business.

“Do we blow away like tumbleweeds? Or do we evolve?” she said in an interview at her gleaming office building in Tioga, N.D. “This is an industry that has a history of adopting, evolving and changing with the nation. I don’t see oil going away in any of our lifetimes. It’s our way of life. Where we lose out on transportation we will gain on new technologies.”

Destiny Wolf, 39, an upbeat advocate for electric vehicles, also feels the stigma of driving a Tesla — in her case a Model 3.Oil workers, Wolf said, see electric vehicles as an attack on their livelihoods. “You know, sitting there at a red light, they drive up, roll down their windows, they start yelling and cursing at me,” she said. “If that’s your existence, it’s really sad.”

Neset said she believes that investment firms, especially those that have signed on to corporate governance protocols that embrace environmental and social goals, “just don’t want to put their capital into new drilling until we figure out a way to handle this in a clean way.”

“In rural America there is very little you can do without that [oil],” Ness said. “We just don’t have opportunities here. It enables us to build schools, rather than close schools.”

Charles Gorecki, CEO of an incubator at the University of North Dakota called the Energy and Environmental Research Center, is promoting a plan similar to the coal industry’s Project Tundra. But it would go further — he envisions the injection of carbon dioxide into deep caverns as a way of enhancing the extraction of more oil. More carbon would go into the ground than would come out of it as petroleum, he said. North Dakota could even import carbon dioxide from other states.

“There is an enormous amount of space to store CO2,” he said. “What we need to do is make it an economically attractive option. The goal is to reduce carbon emissions. It should be by any and all means.”

A new state body called the Clean Sustainable Energy Authority is charged with promoting clean-energy technologies — with the understanding that the energy being talked about is from coal, oil or natural gas. Carbon capture is one idea; another is hydrogen-powered vehicles, using “blue” hydrogen from natural gas.

“Even if we transition to all electric vehicles and hydrogen vehicles, North Dakota will have a part to play,” said Joel Brown, a member of the CSEA. “I think of it as a moonshot for the state of North Dakota.”

In the history of the Bakken, 3 billion barrels of oil have been pumped out. Brown said 30 billion to 40 billion more barrels is still in the ground and recoverable.

“We have to make that Bakken barrel just a little bit cleaner than every other barrel in the world,” said Ron Ness, head of the North Dakota Petroleum Council, a trade group. “You look at the standard American family and the affordability of the combustion engine, and I think gasoline is going to be around for a long time.”

North Dakota went from being the 10th-largest oil-producing state in 2005 to the second in 2015.

Watford City is in McKenzie County, which between 2010 and 2019 was the fastest-growing county in the United States, according to census figures. In the late 1990s, said Steve Holen, the school superintendent, people thought the county would soon have nothing but bison and nursing homes. Oil changed all that, and residents are reluctant to let that go.

So the oil sector, too, is putting its chips on carbon capture.

Consequently, there’s a widespread conviction in the Bakken that electric vehicles will never amount to much. “It’s a cultural challenge,” said Neset. “I’m not sure how many of these cowboys and cowgirls are going to want to jump in an electric car.”

A question about EVs that was put to a Bakken Facebook group elicited scathing, vulgar responses. “Let the retirees living in Florida, Arizona and California buy them. I am from North Dakota, give me a gas guzzling ‘truck,’” wrote one.

“Anyone that supports electric over gas and works in the Bakken is a hypocrite. Your job revolves around oil. No oil = No job for most. Easiest math I have ever done,” wrote another.

“Never, ever, ever,” wrote a third.But there are signs this hostility to electric is cracking.

Finally, executive orders are not the last word in policy. They can be easily revoked.

Regardless, executive orders are not as durable as laws or regulations.

Why don’t presidents always issue executive orders, a seemingly powerful policy device? Because they come with serious constraints.

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.

Losing Earth: The Decade WeAlmost Stopped Climate Change We knew everything we needed to know, and nothing stood in our way. Nothing, that is, except ourselves. A tragedy in two acts. By Nathaniel RichPhotographs and Videos by George Steinmetz AUG. 1, 2018

Lauri Myllyvirta, the centre’s lead analyst, said this was equivalent to about three months of global emissions. “These plants, if built and operated, would have emitted around 250-280 megatonnes of CO2 a year, which is roughly equal to the total emissions of Spain. Assuming an operating life of 35 years, the cumulative emissions would amount to 10 gigatonnes, or a year of China’s emissions, or three months of global emissions,”

there is evidence that 40% of the heavy equipment at new coal plants outside China and India comes from China

With coal now seemingly in terminal decline, climate activists are turning their sights towards oil, gas, and domestic coal power in China and India.

Despite the uncertainties over implementation, Myllyvirta said China’s announcement would accelerate decarbonisation. “Countries now know that going forward, there is no financing on the table for coal. That should clarify things a lot. Chinese delegates are going to visit Indonesia or Vietnam or Pakistan and they will be saying, ‘We don’t do coal any more, but we can help with clean energy.’ That will make a difference.”

Depending on implementation, other possible beneficiaries of this announcement could be the rhinos, giraffes, cheetahs and other endangered species at Zimbabwe’s Hwange national park, where two Chinese companies had hoped to extract the fossil fuel.

Another positive knock-on effect would be to push Japan to follow suit. The government in Tokyo has already taken steps in this direction but left a door open for financing by its private-sector institutions. Their geopolitical reason had been that they did not want to leave China as the only option for regional energy projects.

The immediate impact is likely to be felt in the countries that rely most heavily on Chinese funding for new coal projects: Indonesia, Vietnam, Bangladesh and Pakistan

Close to 58% of its power comes from the country’s 1,058 coal plants, almost half the total in the entire the world. This makes China far the biggest carbon emitter, pumping more than one out of every four gigatonnes that enter the atmosphere.

oughly half the country’s plants will have to close if the government 2060 net-zero target is to be achieved.

In fact, “public health has actively participated in its own marginalization,” Daniel Goldberg, a historian of medicine at the University of Colorado, told me. As the 20th century progressed, the field moved away from the idea that social reforms were a necessary part of preventing disease and willingly silenced its own political voice. By swimming along with the changing currents of American ideology, it drowned many of the qualities that made it most effective.

Germ theory offered a seductive new vision for defeating disease: Although the old public health “sought the sources of infectious disease in the surroundings of man; the new finds them in man himself,” wrote Hibbert Hill in The New Public Health in 1913

“They didn’t have to think of themselves as activists,” Rosner said. “It was so much easier to identify individual victims of disease and cure them than it was to rebuild a city.”

As public health moved into the laboratory, a narrow set of professionals associated with new academic schools began to dominate the once-broad field. “It was a way of consolidating power: If you don’t have a degree in public health, you’re not public health,”

Mastering the new science of bacteriology “became an ideological marker,” sharply differentiating an old generation of amateurs from a new one of scientifically minded professionals,

Hospitals, meanwhile, were becoming the centerpieces of American health care, and medicine was quickly amassing money and prestige by reorienting toward biomedical research

Public health began to self-identify as a field of objective, outside observers of society instead of agents of social change. It assumed a narrower set of responsibilities that included data collection, diagnostic services for clinicians, disease tracing, and health education.

Assuming that its science could speak for itself, the field pulled away from allies such as labor unions, housing reformers, and social-welfare organizations that had supported city-scale sanitation projects, workplace reforms, and other ambitious public-health projects.

That left public health in a precarious position—still in medicine’s shadow, but without the political base “that had been the source of its power,”

After World War II, biomedicine lived up to its promise, and American ideology turned strongly toward individualism.

Seeing poor health as a matter of personal irresponsibility rather than of societal rot became natural.

Even public health began to treat people as if they lived in a social vacuum. Epidemiologists now searched for “risk factors,” such as inactivity and alcohol consumption, that made individuals more vulnerable to disease and designed health-promotion campaigns that exhorted people to change their behaviors, tying health to willpower in a way that persists today.

This approach appealed, too, to powerful industries with an interest in highlighting individual failings rather than the dangers of their products.

“epidemiology isn’t a field of activists saying, ‘God, asbestos is terrible,’ but of scientists calculating the statistical probability of someone’s death being due to this exposure or that one.”

In 1971, Paul Cornely, then the president of the APHA and the first Black American to earn a Ph.D. in public health, said that “if the health organizations of this country have any concern about the quality of life of its citizens, they would come out of their sterile and scientific atmosphere and jump in the polluted waters of the real world where action is the basis for survival.”

a new wave of “social epidemiologists” once again turned their attention to racism, poverty, and other structural problems.

The biomedical view of health still dominates, as evidenced by the Biden administration’s focus on vaccines at the expense of masks, rapid tests, and other “nonpharmaceutical interventions.”

Public health has often been represented by leaders with backgrounds primarily in clinical medicine, who have repeatedly cast the pandemic in individualist terms: “Your health is in your own hands,” said the CDC’s director, Rochelle Walensky, in May

the pandemic has proved what public health’s practitioners understood well in the late 19th and early 20th century: how important the social side of health is. People can’t isolate themselves if they work low-income jobs with no paid sick leave, or if they live in crowded housing or prisons.

Public health is now trapped in an unenviable bind. “If it conceives of itself too narrowly, it will be accused of lacking vision … If it conceives of itself too expansively, it will be accused of overreaching,

“Public health gains credibility from its adherence to science, and if it strays too far into political advocacy, it may lose the appearance of objectivity,”

In truth, public health is inescapably political, not least because it “has to make decisions in the face of rapidly evolving and contested evidence,” Fairchild told me. That evidence almost never speaks for itself, which means the decisions that arise from it must be grounded in values.

Those values, Fairchild said, should include equity and the prevention of harm to others, “but in our history, we lost the ability to claim these ethical principles.”

“Sick-leave policies, health-insurance coverage, the importance of housing … these things are outside the ability of public health to implement, but we should raise our voices about them,” said Mary Bassett, of Harvard, who was recently appointed as New York’s health commissioner. “I think we can get explicit.”

The future might lie in reviving the past, and reopening the umbrella of public health to encompass people without a formal degree or a job at a health department.

What if, instead, we thought of the Black Lives Matter movement as a public-health movement, the American Rescue Plan as a public-health bill, or decarceration, as the APHA recently stated, as a public-health goal? In this way of thinking, too, employers who institute policies that protect the health of their workers are themselves public-health advocates.

“We need to re-create alliances with others and help them to understand that what they are doing is public health,

The biggest question thrown up by this history is why the West failed to see the danger earlier.

The North Atlantic Treaty Organization made a statement in 2008 that Ukraine and Georgia would one day join, and over nearly 14 years never followed through on membership. The EU drew up a trade deal with Ukraine without factoring in Russia’s strong-arm response. Western policies didn’t change decisively in reaction to limited Russian invasions of Georgia and Ukraine, encouraging Mr. Putin to believe that a full-blown campaign to conquer Ukraine wouldn’t meet with determined resistance—either internationally or in Ukraine, a country whose independence he said repeatedly was a regrettable accident of history.

The roots of the war lie in Russia’s deep ambivalence about its place in the world after the end of the Soviet Union

Viewed from elsewhere in Europe, NATO’s eastward enlargement didn’t threaten Russia’s security. NATO membership is at core a promise to collectively defend a member that comes under attack. The alliance agreed in 1997 not to permanently station substantial combat forces in its new eastern members that were capable of threatening Russian territory. Russia retained a massive nuclear arsenal and the biggest conventional forces in Europe.

Mr. Putin thought of Russian security interests more broadly, linking the preservation of Moscow’s influence in adjacent countries with his goals of reviving Russia’s global power and cementing his authoritarian rule at home.

U.S. intelligence learned in 2005 that Mr. Putin’s government had carried out a broad review of Russian policy in the “near abroad,” as the Kremlin termed former Soviet republics. From now on, Russia would take a more assertive approach and vigorously contest perceived U.S. influence.

Mr. Bush asked Mr. Putin why he thought the end of the Soviet Union had been the greatest tragedy of the 20th century. Surely the deaths of more than 20 million Soviet citizens in World War II was worse, Mr. Bush said. Mr. Putin replied that the USSR’s demise was worse because it had left 25 million Russians outside the Russian Federation, according to Ms. Rice, who was present.

Perceptions changed in January 2007, when Mr. Putin vented his growing frustrations about the West at the annual Munich Security Conference. In a long and icy speech, he denounced the U.S. for trying to rule a unipolar world by force, accused NATO of breaking promises by expanding into Europe’s east, and called the West hypocritical for lecturing Russia about democracy. A chill descended on the audience of Western diplomats and politicians at the luxury Hotel Bayerischer Hof, participants recalled.

“We didn’t take the speech as seriously as we should have,” said Mr. Ischinger. “It takes two to tango, and Mr. Putin didn’t want to tango any more.

“I need a MAP. We need to give the Ukrainian people a strategic focus on the way ahead. We really need this,” Mr. Yushchenko said, Ms. Rice recalled. Ms. Rice, who was initially uncertain about having Ukraine in NATO, gave a noncommittal answer. When the request was debated in the National Security Council, Mr. Bush said NATO should be open to all countries that qualify and want to join.

Try as it might, the White House couldn’t overcome German and French resistance to offering a MAP to Ukraine and Georgia.

Berlin and Paris pointed to unsolved territorial conflicts in Georgia, low public support for NATO in Ukraine, and the weakness of democracy and the rule of law in both.

Ms. Merkel, remembering Mr. Putin’s speech in Munich, believed he would see NATO invitations as a direct and deliberate threat to him, according to Christoph Heusgen, her chief diplomatic adviser at the time. She was also convinced Ukraine and Georgia would bring NATO no benefits as members, Mr. Heusgen said.

Ms. Rice, a Soviet and Russia expert, said Mr. Putin wanted to use Ukraine, Belarus and Georgia to rebuild Russia’s global power, and that extending the shield of NATO membership could be the last chance to stop him. German and French officials were skeptical, believing Russia’s economy was too weak and dependent on Western technology to become a serious threat again.

In the final session, Ms. Merkel debated in a corner of the room with leaders from Poland and other eastern members of NATO, who advocated strenuously on behalf of Ukraine and Georgia. Lithuanian President Valdas Adamkus strongly criticized Ms. Merkel’s stance, warning that a failure to stop Russia’s resurgence would eventually threaten the eastern flank of the alliance.
