The question, it seems to me, is one of proportion.

The average aid for high-income countries like Israel, according to USAID, is $79 million a year. Israel gets 48 times more.

In return for giving Israel $3.8 billion a year … the U.S. is expected to consent to anything and everything Israel wants. When you look at this from a distance, it is really quite amazing.

And, of course, Israel won in the end. Under Trump, Israel has achieved almost every goal it aimed for: the scrapping of the Iran deal, the recognition of Jerusalem as Israel’s capital, moving the U.S. embassy to Jerusalem, a surge in settlements, and an intensification of the abuse of the Palestinians

Again you might ask: What did the U.S. get in return for all this from Israel? And again the answer is: Nothing.

Actually, worse than nothing. The U.S. suffers internationally from this alliance. Don’t take it from me. Here’s General James Mattis: “I paid a military price every day as the commander at CentCom because the Americans were perceived as biased toward Israel and that moderates all the moderate Arabs who want to be with us.” Or David Petraeus: “The conflict foments anti-American sentiment, due to a perception of American favoritism toward Israel.”

Now observe the public discourse in Washington. Here is Nancy Pelosi last year: “If this capitol crumbled to the ground, the one thing that would remain would be our commitment to aid — I won’t even call it aid — our cooperation with Israel.” Chew on that a minute. If the United States were to collapse, its one objective would be to aid a foreign country

The first bill introduced into the Senate in this Congress was one that made it illegal for any American to boycott goods from the West Bank, without suffering real economic consequences from their own government. It’s a federal bill designed to buttress several state bans on Americans’ right to boycott Israeli goods. Now here’s a clear case of conflict between the free speech rights of Americans and Israel’s continuing occupation of the West Bank. And the Senate voted for Israel’s occupation over the rights of its own citizens by a margin of 77– 23

It seems to me that it is simply a fact that the Israel lobby uses money, passion, and persuasion to warp this country’s foreign policy in favor of another country — out of all proportion to what Israel can do for the U.S.

History matters. But it’s not a rational way for a great power to conduct foreign polic

The one-way street has also corrupted Israel, wrecked its moral standing, and enabled the country to keep ratcheting toward the far right in self-destructive ways.

The reason seems quite simple: Migrants now know that the U.S. border system is overwhelmed. More to the point, they now know that if they bring their children with them, they will not be abruptly sent back, and cannot be detained for longer than 20 days, after which they will be free to go and work anywhere in the country. That incentive is much stronger now than it was a year ago

What has happened in Guatemala to produce such a growing mass of asylum seekers? The truth appears to be some food insecurity after a failed harvest — but mostly the news that the U.S. border is effectively open, and if you bring your kids and show up, you’re home free

The Democrats for their part keep saying that there is no crisis at all, berate the administration for insufficient care or tougher enforcement at ports of entry, and actually attempted to restrict the number of beds assigned for detention in their last negotiation with the president (it didn’t happen). At some point, they’re going to have to grapple with this genuine emergency.

But how do we stop this? Congress has to act to change the law that enables this. Asylum, traditionally understood, was once for those fleeing political or ethnic persecution. It wasn’t a catch-all for any economic migrant, who can be coached to say the right words to the right official. It’s a vast loophole in the immigration system — and if it isn’t fixed legislatively soon, the current massive wave will keep building

If you think that won’t empower more nativist demagogues and help reelect Trump, you’re dreaming.

“among white liberals … 79.2 percent agreed that ‘racial discrimination is the main reason why many black people can’t get ahead these days.’ 18.8 percent agreed that ‘blacks who can’t get ahead in this country are mostly responsible for their own condition. … Among blacks, 59.9 percent identified discrimination as the main deterrent to upward mobility for African-Americans, and 32.0 percent said blacks were responsible for their condition.”

These white super-liberals are also, according to a fascinating survey featured in The Atlantic, the most blinkered. Money quote: “The most politically intolerant Americans, according to the analysis, tend to be whiter, more highly educated, older, more urban, and more partisan themselves

The survey found that the city most intolerant of other people’s views was Boston, specifically around Cambridge

This most tolerant town is in a county that voted for Trump by a 20-point margin. Let’s absorb that fact for a while, shall we?

the results suggest a damning verdict on American higher education. My alma mater Harvard, a university where free speech, ideological differences, and competing arguments should flourish is, in fact, a nest of smug intolerance. Our elite colleges may be the most “diverse” ever. But they have also become machines for closing students’ minds.

In the 19th century, the secularization of Western society led to the secularization of pain. It was no longer a passion to be endured but a sensation to be quashed.

The concept of pain as a purely physical phenomenon reached its zenith in the 1990s

having pain designated a “fifth vital sign,” alongside blood pressure, temperature and breathing and heart rate.

This coincided with the release of long-acting opioids like OxyContin. Doctors believed they now had an effective remedy for their patients’ suffering

looking back it’s clear that using opioids to treat chronic pain — backaches, bum knees and the like — might well be considered the worst medical mistake of our era.

ecades of research suggests that opiates provide little to no benefit for chronic noncancer pain

Why is this? Studies have shown that opioids can reduce patients’ pain thresholds.

They can also result in a condition called opioid-induced hyperalgesia, in which people feel more and more pain as they are prescribed higher and higher doses of opioids

the mind does play a pivotal role in the experience of pain. After a pain signal reaches the brain, it undergoes significant reprocessing.

How much something hurts can vary depending on factors like your expectations, your mood and how distracted you are

pain is contagious and transmittable.

Conditions like depression and anxiety greatly increase the chance of developing chronic pain, while patients who experience pain are at high risk of developing depression or anxiety

there is considerable overlap in the areas of the brain that deal with pain and emotion.

Objectively, there is no doubt that illnesses and injuries can cause immense suffering. The question is how severe that suffering is, and how long it lasts

pain sensitivity varies significantly among people, most likely as a result of genetic differences.

rug companies greatly underplayed the risks of opioids, while billions of dollars in marketing told people that pills were the only answer to their ailments.

future doctors should be taught that pain is part of the story of the person who suffers from it, not just a separate physical phenomenon.

this education should incorporate ways to avoid prescribing opioids for chronic use.

Perhaps the most important tool physicians need to manage pain is empathy.

Physical therapy that doesn’t just manipulate joints but also addresses the context pain comes alive in, encourages optimism and builds emotional resilience has been found to be more effective.

unfortunately our health system encourages doctors to see as many patients as possible as quickly as possible. We need to change how physicians are paid in order to give them the time to really talk with patients about their pain.

I felt that the pain was my body’s way of telling me that something was wrong, and I didn’t want to silence that voice with a temporary fix.

What pulled me out after almost a year of agony was not just rigorous physical therapy that molded my spine back into shape but also the kindness of my friends, my family and my future wife.

a spiritual and emotional experience alleviated through prayers rather than prescriptions.

"There is no doubt in my mind that the President of the United States broke his oath of office and incited this insurrection. He used his position in the Executive to attack the Legislative."

'll say to anybody that thinks my vote was for politics, they don't know me. And I would say now they don't know politics because, you know, you have to get through a primary,"

Concerns over his future within the party aren't without merit. Several House Republicans have hammered Rep. Liz Cheney of Wyoming, the party's third-ranking House leader, calling for her to step down from her leadership position over her vote to impeach Trump. She's also facing a primary challenge from a prominent conservative state legislator.

"I'm more passionate about this country than I think I was January 5, even," he continued. "I know my passion is the restoration of the Republican Party. I know I may go down fighting like that."

"I think this is one of those votes that that transcends any kind of political implication of the moment," Kinzinger said at the time. "This is one of those that you're going to look back on when you're 80 and this will be the one you talk about."

Kinzinger also said at the time that he didn't feel pressure from the party but that his constituents were all over the place

Will’s 1983 book, Statecraft as Soulcraft, had a significant intellectual impact on me. He questioned the Founders’ faith that moral balance and national cohesiveness will be supplied by the government’s doing little more than encouraging the free operation of “opposite and rival interests.”

when a political regime establishes, through laws and courts and customs and other matters, a particular political economy, it is establishing, it is choosing the kind of people that would live under that regime,”

The Conservative Sensibility suggests something else: that we should be attending more to the machinery of government and that government should be far less concerned about inculcating virtue in the citizenr

“It turns out that Madison was smarter than I am.” When he argued that America was ill-founded because insufficient attention was given to soulcraft, he explained, he hadn’t fully appreciated that the Founders were indeed arguing about statecraft as soulcraft—that a government really can inculcate virtue.

America was “ill-founded,” he wrote, because there was not enough attention to what he termed “the sociology of virtue.” Government needed to take a greater role in shaping the moral character of its citizens

Will argues that Trump’s agenda, to the degree it pleases conservatives, is what any Republican president would have done. “So the question is what does Trump bring that's distinctive?” Will said. “And it's all vulgarity, coarsening, semi-criminality.

long story short: I did not appreciate the extent to which Madisonian liberty with Hamiltonian energy is soulcraft.”

Will has claimed that Trump has done more lasting damage than Richard Nixon did during the Watergate scandal because, in Will’s words, “you can't un-ring the bell. You can't unsay what he has now said is acceptable discourse in the United States.

he hoped Trump supporters are right—but he’s pretty sure they are wrong when they say that what Trump is doing to our culture, our politics and our civic discourse is ephemeral.

He argues in The Conservative Sensibility that capitalism doesn't just make us better off; it makes us better by enforcing such virtues as thrift, industriousness, and the deferral of gratification.

asking about the concrete, tangible harm of Trump’s conduct.“The answer is in the terms themselves,” Will replied. “The norms, that is, what are normal and what are normative, cease to be normal. And cease to be normative.

“It’s amazing to me how fast, and we saw this in the 20th century in a number of ways, how fast something could go from unthinkable to thinkable to action,”

“And it doesn’t seem to me it’s going to be easy to just snap back as if this didn’t happen. It happened. And he got away with it. And he became president. And there will be emulators.”

Those who may have forgotten are now being reminded that government has a vital role in the cultivation and sustenance—or in the degradation and destruction—of political cultures. Which brings us back to Statecraft as Soulcraft.

“mankind is not just matter, not just a machine with an appetitive ghost in it. We are not what we eat. We are, to some extent, what we and our leaders—the emblematic figures of our polity—say we are.”

“What I’d like progressives to take away from the book is a reconsideration of their dilemma,

in 1964, when I cast my first presidential vote for Barry Goldwater, to whose memory the book is dedicated, 77 percent of the American people said they trusted the government to do the right thing all the time or almost all the time. Today it's 17 percent—and that 60-point evaporation of government prestige has accompanied a 60-fold increase in government pretensions.

their entire agenda depends on strong government and strong government depends on public confidence in the government.”

“What I'd like conservatives to take away from this book,” Will added, “is the sense of the enormous intellectual pedigree behind conservatism from Madison to Lincoln to Hayek and the rest.” Will said conservatives need to answer the question: What does conservatism want to conservative?

The most important of all revolutions, Edmund Burke said, is a “revolution in sentiment, manners and moral opinion.”

what we think Trump supporters either don’t understand or deny, is the destructive revolution in manners and mores that Donald Trump is ushering in, the enormous cultural and social blast radius of his presidency. Through his promiscuous lying and assault on demonstrable truths, his cruelty and crudity, his coarseness, bullying and dehumanization of his opponents, and his lawlessness and conspiracy-mongering—the whole corrupt, packaged deal—he has brought us into dark new realms.

Will, who earned his Ph.D. in politics at Princeton and later taught political philosophy

hen I probed Will on what has gone wrong with the American right, he mentioned the anti-intellectualism that inevitably comes with populism, which he called “the obverse of conservatism.”

“Populism is a direct translation of popular passions into governments through a strong executive. Someone who might say something like, ‘Only I can fix it.

Will argued that James Madison understood the need to “filter and refine and deflect and slow public opinion through institutions. To make it more refined, to produce what Madison called, in one of his phrases that I’m particularly fond of, ‘mitigated democracy.’

what would most concern the Founders about contemporary politics. “Political leaders today seem to feel that their vocation is to arouse passions,” he told me, “not to temper and deflect and moderate them.

Will has claimed that Trump has done more lasting damage than Richard Nixon did during the Watergate scandal because, in Will’s words, “you can’t un-ring the bell. You can’t unsay what he has now said is acceptable discourse in the United States.”

Will replied that he hoped Trump supporters are right—but he’s pretty sure they are wrong when they say that what Trump is doing to our culture, our politics, and our civic discourse is ephemeral.

Will argues that Trump’s agenda, to the degree it pleases conservatives, is what any Republican president would have done. “So the question is, What does Trump bring that’s distinctive?” Will said. “And it’s all vulgarity, coarsening, semi-criminality.”

Trump’s supporters on the right “misunderstand the importance of culture, the viscosity of culture, and I think they are not conservatives, because they don’t understand this,”

Donald Trump promised when he ran for president that he would overturn our norms, Will has said, and that’s one promise he’s kept.

All of us, including Will, have to deal with the fact that we are now confronted with a head of government who is systematically assaulting our ideals and virtues

“To revitalize politics and strengthen government, we need to talk about talk. We need a new, respectful rhetoric—respectful, that is, of the better angels of mankind’s nature.

And their dilemma is this: In 1964, when I cast my first presidential vote for Barry Goldwater, to whose memory the book is dedicated, 77 percent of the American people said they trusted the government to do the right thing all the time or almost all the time. Today, it’s 17 percent—and that 60-point evaporation of government prestige has accompanied a 60-fold increase in government pretensions.

I would think my progressive friends would be alarmed by this, because their entire agenda depends on strong government, and strong government depends on public confidence in the government.”

Will said conservatives need to answer the question, What does conservatism want to conserve?

For Will, the answer is the American founding, by which he has in mind three things: the doctrine of natural rights, understood as rights essential to the flourishing of creatures with our natures; a belief in human nature, meaning we are more than creatures who absorb whatever culture we’re situated in; and a government architecture, principally the separation of powers, that is essential to making good on what he refers to as the most crucial verb in the Declaration of Independence.

What conservatives like Will and me believe, and what we think Trump supporters either don’t understand or deny, is the destructive revolution in manners and mores that Donald Trump is ushering in

Through his promiscuous lying and assault on demonstrable truths, his cruelty and crudity, his coarseness, bullying ,and dehumanization of his opponents, and his lawlessness and conspiracy-mongering—the whole corrupt, packaged deal—he has brought us into dark new realms.

There was a time when Republicans and conservatives more generally insisted that culture was upstream of politics and in many respects more important than politics; that leaders needed to take great care in cultivating and validating standards of decency, honor, and integrity; and that a president who destroyed rather than defended cultural norms and high standards would do grave injury to America.

now Republicans are willing to sacrifice soul and culture for the sake of promised policy victories.

“If the great columnists got a single sentence in the history books,” I asked Will, “what would you want to say about your contribution?”

“It would be to convince people that politics is both fun and dignifies—that it has a great and stately jurisdiction, because and to the extent that it is a politics of ideas. Period.

“The American nation’s finest political career derived from Lincoln’s refusal to allow his country to be seduced into thinking of itself in an unworthy way,”

the civic virtues that Madison and the other Founders believed were essential for a free republic to survive “must be willed. It is folly to will an end but neglect to will the means to the end. The presuppositions of our polity must be supplied, politically.”

"The Women's March has had a history of marginalizing certain people. They want their version of smashing patriarchy to look a certain way,"

A different group of protesters also stopped in front of the White House to chant the words of Article 2, Section 4 of the Constitution in reference to President Trump's impeachment.

in the long arc of the Limbaugh era, you can see pretty clearly how success and self-marginalization can be effectively combined.

Reaganite conservatism in ’80s America was a 55 percent proposition, popular with younger voters, with only a mild version of today’s yawning gender gap.

But you don’t need 55 percent of the country to build a huge talk-radio audience or an incredibly successful cable news network or a vast online ecosystem. You need a passionate audience, a committed audience, a church of Dittoheads.That was what Limbaugh built for himself

then everyone else on the right went in the same direction: First, Limbaugh’s talk radio imitators, then Roger Ailes with Fox News, and then — disastrously — a great many Republican politicians, who realized that an intense ideological fan base was enough to win them elections in safe districts and might make them media celebrities in the bargain.

This pattern created problems that compounded one another. As Conservatism Inc. became more of a world unto itself, it sealed out bad news for conservative governance, contributing to debacles that doomed Republican presidents — Iraq for George W. Bush, Covid for Donald Trump

These debacles helped make conservatism less popular, closer to a 45 percent than a 55 percent proposition in presidential races, a blocking coalition but not a governing one.

And this in turn made the right’s passionate core feel more culturally besieged, more desperate for “safe spaces” where liberal perfidy was taken for granted and the most important reasons for conservative defeats were never entertained.

Such a system, predictably, was terrible at generating the kind of outward-facing, evangelistic conservatives who had made the Reagan revolution possible

to go back and watch Reagan and Buckley is to see an entirely different approach to politics — missionary and confident, with a gentlemanly comportment that has altogether vanished.

In its place today is a fantasy politics, a dreampolitik, that’s fed by a deep feeling of grievance and dispossession.

the right’s infotainment complex is itself a major reason for that consolidation. Conservatives have lost real-world territory by building dream palaces, and ceded votes by talking primarily to themselves.

Dan McLaughlin, in an instructive piece for National Review, counts Limbaugh as one of the right’s five most important 1990s-era figures, along with Ailes, Rudy Giuliani, Newt Gingrich and Antonin Scalia

as they grew old within the right’s infrastructure, Limbaugh and Ailes and Newt and Rudy all seemed to cede their individuality and converge into a single character, a single noisy voice.

Which were the media impresarios and which were the political leaders? Which one was married four times, which ones only three, which was the office predator? Which one was most likely to say something indefensible in defense of Donald Trump?

Only Scalia, secure from certain temptations in his lifetime judicial appointment, retained both his individuality and his outward-facing influence to the end.

For the rest, for Limbaugh especially, we can say that their gifts were ample, their ascent remarkable, their influence enduring — and yet their most important legacy has been ashes and defeat.

Trump is gambling that the language some protesters have adopted, combined with the commitment of big-city mayors like Bill de Blasio and Eric Garcetti, to cut or divert police spending, along with the pledge of a majority of the Minneapolis City Council to dismantle the city’s police department, will keep moderate voters who supported Trump in 2016 in the Republican fold.

A May 29-30 YouGov poll found that when voters were asked whether they support calls to “cut funding for police departments,” both Democrats (62-16) and Republicans (75-15) were solidly opposed.

Morning Consult posed the question: “Who would you say is most responsible for inciting violence during the nationwide protests,” the protesters or the police? The result: 45 percent placed responsibility for the violence on the protesters, 35 percent on the police and 20 percent could not decide.

In the wake of the Civil Rights Movement, we certainly saw both white Republican and Democrats’ sympathy for racial equality wane, especially after persistent protests. Hopefully the attitude change we are observing now is less fragile, but the march toward racial equality in the U.S. has historically been long, winding, and marked by setbacks.

Todd Gitlin, a professor of journalism and sociology at Columbia and author of “The Sixties: Years of Hope, Days of Rage,” wrote that the George Floyd protests stand, to some degree, in contrast to the movements of the 1960s:Young/student/white passion 1960-68 was driven initially by solidarity with blacks; that passion then morphed into the antiwar movement and the larger New Left. It had a utopian edge, driven by hope for a whole new world, thus bleeding over into what came to be called the counterculture. The lasting impact was cultural more than directly political; in fact, the New Left was downright anti-political.

Now, Scott continued,I look at the public’s response to this situation and it feels like the first time in my lifetime that I’ve heard law enforcement agencies coming out with strong rebukes and condemnation of the officers in Minneapolis.

he white working class has a deep-rooted — and well-founded — sense that the system is failing them. A facile lurch to the “left” that doesn’t take into account their concerns — which once were the dominant concerns of the left — would be costly.

In order to make progress in race relations, Inglehart argues,We need to move there with a balanced approach, not a one-sided lurch — especially since today’s context of economic and physical insecurity makes people increasingly vulnerable to xenophobic appeals.

Particularly worrisome for Democrats, according to Cain, “is the growing popularity of defunding the police.” He noted thatterms like defunding the police or abolition are ready made for Republican 30 second ads. The Republicans are just much better at coming up with slogans that are harder to attack.

Most change, Vaisey argued, “occurs through the death of older cohorts and their replacement by younger cohorts,” and such slow, long-term movement is now happening.

Young people really are changing (probably up to somewhere around age 25-30 or so). This means that we may be witnessing the formation of a cohort with genuinely different views on race relations. People 25 and below are probably having their opinions changed in a major way on this. So that will have effects on politics now and down the road, especially as current teenagers age into legal and more regular voting age.

Today, Gitlin wrote,I see strong signs of the new activists getting serious about registering voters, doing local politics, then turning to turnout in the fall. They want laws to change. They want policies changed. They know they’re not going to accomplish such goals by cursing the police.

When Scott looked out his window in Washington at an overwhelmingly young crowd, he said he saw “10 protesters. Seven of them are white, and three of them are black.” Without question, Scott declared, “This is different. It feels different. It sounds different. The protesters are different.”

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.

It was nearly freezing — Nov. 6, 1989, on the coast of the North Sea in the Dutch resort town of Noordwijk

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

In 1981, Huntington predicted that the next moral convulsion would hit America around the second or third decade of the 21st century—that is, right about now.

Trump is the final instrument of this crisis, but the conditions that brought him to power and make him so dangerous at this moment were decades in the making, and those conditions will not disappear if he is defeated.

Social trust is a measure of the moral quality of a society—of whether the people and institutions in it are trustworthy, whether they keep their promises and work for the common g

When people in a society lose faith or trust in their institutions and in each other, the nation collapses.

This is an account of how, over the past few decades, America became a more untrustworthy society

under the stresses of 2020, American institutions and the American social order crumbled and were revealed as more untrustworthy still

We had a chance, in crisis, to pull together as a nation and build trust. We did not. That has left us a broken, alienated society caught in a distrust doom loop.

The Baby Boomers grew up in the 1950s and ’60s, an era of family stability, widespread prosperity, and cultural cohesion. The mindset they embraced in the late ’60s and have embodied ever since was all about rebelling against authority, unshackling from institutions, and celebrating freedom, individualism, and liberation.

The emerging generations today enjoy none of that sense of security. They grew up in a world in which institutions failed, financial systems collapsed, and families were fragile. Children can now expect to have a lower quality of life than their parents, the pandemic rages, climate change looms, and social media is vicious. Their worldview is predicated on threat, not safety.

Thus the values of the Millennial and Gen Z generations that will dominate in the years ahead are the opposite of Boomer values: not liberation, but security; not freedom, but equality; not individualism, but the safety of the collective; not sink-or-swim meritocracy, but promotion on the basis of social justice

A new culture is dawning. The Age of Precarity is here.

I’ve spent my career rebutting the idea that America is in decline, but the events of these past six years, and especially of 2020, have made clear that we live in a broken nation. The cancer of distrust has spread to every vital organ.

Those were the days of triumphant globalization. Communism was falling. Apartheid was ending. The Arab-Israeli dispute was calming down. Europe was unifying. China was prospering. In the United States, a moderate Republican president, George H. W. Bush, gave way to the first Baby Boomer president, a moderate Democrat, Bill Clinton.

The stench of national decline is in the air. A political, social, and moral order is dissolving. America will only remain whole if we can build a new order in its place.

The American economy grew nicely. The racial wealth gap narrowed. All the great systems of society seemed to be working: capitalism, democracy, pluralism, diversity, globalization. It seemed, as Francis Fukuyama wrote in his famous “The End of History?” essay for The National Interest, “an unabashed victory for economic and political liberalism.”

Nations with low social trust—like Brazil, Morocco, and Zimbabwe—have struggling economies.

We think of the 1960s as the classic Boomer decade, but the false summer of the 1990s was the high-water mark of that ethos

The first great theme of that era was convergence. Walls were coming down. Everybody was coming together.

The second theme was the triumph of classical liberalism. Liberalism was not just a philosophy—it was a spirit and a zeitgeist, a faith that individual freedom would blossom in a loosely networked democratic capitalist world. Enterprise and creativity would be unleashed. America was the great embodiment and champion of this liberation.

The third theme was individualism. Society flourished when individuals were liberated from the shackles of society and the state, when they had the freedom to be true to themselves.

For his 2001 book, Moral Freedom, the political scientist Alan Wolfe interviewed a wide array of Americans. The moral culture he described was no longer based on mainline Protestantism, as it had been for generations

Instead, Americans, from urban bobos to suburban evangelicals, were living in a state of what he called moral freedom: the belief that life is best when each individual finds his or her own morality—inevitable in a society that insists on individual freedom.

moral freedom, like the other dominant values of the time, contained within it a core assumption: If everybody does their own thing, then everything will work out for everybody.

This was an ideology of maximum freedom and minimum sacrifice.

It all looks naive now. We were naive about what the globalized economy would do to the working class, naive to think the internet would bring us together, naive to think the global mixing of people would breed harmony, naive to think the privileged wouldn’t pull up the ladders of opportunity behind them

Over the 20 years after I sat with Kosieva, it all began to unravel. The global financial crisis had hit, the Middle East was being ripped apart by fanatics. On May 15, 2011, street revolts broke out in Spain, led by the self-declared Indignados—“the outraged.” “They don’t represent us!” they railed as an insult to the Spanish establishment. It would turn out to be the cry of a decade.

Millennials and members of Gen Z have grown up in the age of that disappointment, knowing nothing else. In the U.S. and elsewhere, this has produced a crisis of faith, across society but especially among the young. It has produced a crisis of trust.

Social trust is a generalized faith in the people of your community. It consists of smaller faiths. It begins with the assumption that we are interdependent, our destinies linked. It continues with the assumption that we share the same moral values. We share a sense of what is the right thing to do in different situations

gh-trust societies have what Fukuyama calls spontaneous sociability. People are able to organize more quickly, initiate action, and sacrifice for the common good.

When you look at research on social trust, you find all sorts of virtuous feedback loops. Trust produces good outcomes, which then produce more trust. In high-trust societies, corruption is lower and entrepreneurship is catalyzed.

Higher-trust nations have lower economic inequality, because people feel connected to each other and are willing to support a more generous welfare state.

People in high-trust societies are more civically engaged. Nations that score high in social trust—like the Netherlands, Sweden, China, and Australia—have rapidly growing or developed economies.

Renewal is hard to imagine. Destruction is everywhere, and construction difficult to see.

As the ethicist Sissela Bok once put it, “Whatever matters to human beings, trust is the atmosphere in which it thrives.”

During most of the 20th century, through depression and wars, Americans expressed high faith in their institutions

In 1964, for example, 77 percent of Americans said they trusted the federal government to do the right thing most or all of the time.

By 1994, only one in five Americans said they trusted government to do the right thing.

Then came the Iraq War and the financial crisis and the election of Donald Trump. Institutional trust levels remained pathetically low. What changed was the rise of a large group of people who were actively and poi

sonously alienated—who were not only distrustful but explosively distrustful. Explosive distrust is not just an absence of trust or a sense of detached alienation—it is an aggressive animosity and an urge to destroy. Explosive distrust is the belief that those who disagree with you are not just wrong but illegitimate

In 1997, 64 percent of Americans had a great or good deal of trust in the political competence of their fellow citizens; today only a third of Americans feel that way.

In most societies, interpersonal trust is stable over the decades. But for some—like Denmark, where about 75 percent say the people around them are trustworthy, and the Netherlands, where two-thirds say so—the numbers have actually risen.

In America, interpersonal trust is in catastrophic decline. In 2014, according to the General Social Survey conducted by NORC at the University of Chicago, only 30.3 percent of Americans agreed that “most people can be trusted,”

Today, a majority of Americans say they don’t trust other people when they first meet them.

There’s evidence to suggest that marital infidelity, academic cheating, and animal cruelty are all on the rise in America, but it’s hard to directly measure the overall moral condition of society—how honest people are, and how faithful.

Trust is the ratio between the number of people who betray you and the number of people who remain faithful to you. It’s not clear that there is more betrayal in America than there used to be—but there are certainly fewer faithful supports around people than there used to be.

Hundreds of books and studies on declining social capital and collapsing family structure demonstrate this. In the age of disappointment, people are less likely to be surrounded by faithful networks of people they can trust.

Black Americans have high trust in other Black Americans; it’s the wider society they don’t trust, for good and obvious reasons

As Vallier puts it, trust levels are a reflection of the moral condition of a nation at any given time.

high national trust is a collective moral achievement.

High national distrust is a sign that people have earned the right to be suspicious. Trust isn’t a virtue—it’s a measure of other people’s virtue.

Unsurprisingly, the groups with the lowest social trust in America are among the most marginalized.

Black Americans have been one of the most ill-treated groups in American history; their distrust is earned distrust

In 2018, 37.3 percent of white Americans felt that most people can be trusted, according to the General Social Survey, but only 15.3 percent of Black Americans felt the same.

People become trusting when the world around them is trustworthy. When they are surrounded by people who live up to their commitments. When they experience their country as a fair place.

In 2002, 43 percent of Black Americans were very or somewhat satisfied with the way Black people are treated in the U.S. By 2018, only 18 percent felt that way, according to Gallup.

The second disenfranchised low-trust group includes the lower-middle class and the working poor.

this group makes up about 40 percent of the country.

“They are driven by the insecurity of their place in society and in the economy,” he says. They are distrustful of technology and are much more likely to buy into conspiracy theories. “They’re often convinced by stories that someone is trying to trick them, that the world is against them,”

the third marginalized group that scores extremely high on social distrust: young adults. These are people who grew up in the age of disappointment. It’s the only world they know.

In 2012, 40 percent of Baby Boomers believed that most people can be trusted, as did 31 percent of members of Generation X. In contrast, only 19 percent of Millennials said most people can be trusted

Seventy-three percent of adults under 30 believe that “most of the time, people just look out for themselves,” according to a Pew survey from 2018. Seventy-one percent of those young adults say that most people “would try to take advantage of you if they got a chance.

A mere 10 percent of Gen Zers trust politicians to do the right thing.

Only 35 percent of young people, versus 67 percent of old people, believe that Americans respect the rights of people who are not like them.

Fewer than a third of Millennials say America is the greatest country in the world, compared to 64 percent of members of the Silent Generation.

“values and behavior are shaped by the degree to which survival is secure.” In the age of disappointment, our sense of safety went away

Some of this is physical insecurity: school shootings, terrorist attacks, police brutality, and overprotective parenting at home

the true insecurity is financial, social, and emotional.

By the time the Baby Boomers hit a median age of 35, their generation owned 21 percent of the nation’s wealth

First, financial insecurity

As of last year, Millennials—who will hit an average age of 35 in three years—owned just 3.2 percent of the nation’s wealth.

Next, emotional insecurity:

fewer children growing up in married two-parent households, more single-parent households, more depression, and higher suicide rates.

Then, identity insecurity.

All the traits that were once assigned to you by your community, you must now determine on your own: your identity, your morality, your gender, your vocation, your purpose, and the place of your belonging. Self-creation becomes a major anxiety-inducing act of young adulthood.

Finally, social insecurity.

n the age of social media our “sociometers”—the antennae we use to measure how other people are seeing us—are up and on high alert all the time. Am I liked? Am I affirmed?

Danger is ever present. “For many people, it is impossible to think without simultaneously thinking about what other people would think about what you’re thinking,” the educator Fredrik deBoer has written. “This is exhausting and deeply unsatisfying. As long as your self-conception is tied up in your perception of other people’s conception of you, you will never be free to occupy a personality with confidence; you’re always at the mercy of the next person’s dim opinion of you and your whole deal.”

In this world, nothing seems safe; everything feels like chaos.

Distrust sows distrust. It produces the spiritual state that Emile Durkheim called anomie, a feeling of being disconnected from society, a feeling that the whole game is illegitimate, that you are invisible and not valued, a feeling that the only person you can really trust is yourself.

People plagued by distrust can start to see threats that aren’t there; they become risk averse
