Should our politicians fail to reform regulations for internet platforms and digital advertising, our political future will be at risk. The 2016 election revealed the tremendous harm to the American democratic process that can result from coordinated misinformation campaigns; 2020 will be far worse if we do nothing to contain the capacity for politicians to lie on social media.

This new Facebook policy opens a frightening new world for political communication — and for national politics. It is now the case that leading politicians can openly spread political lies without repercussion. Indeed, the Trump campaign was already spreading other falsehoods through online advertising immediately before Facebook made its announcement — and as one might predict, most of those advertisements have not been removed from the platform.

It is disconcerting to think that by fiat, Facebook can deem a political ad to be dishonest because it contains fake buttons (which can deceive the viewer into clicking on a survey button when in fact there is no interactive feature in the ad), but the company will refuse to take action against ads containing widely-debunked political lies, even during an American presidential election.

Facebook has one principal counterargument against regulation: that the company must maintain strong commitments to free speech and freedom of political expression. This came across in Mark Zuckerberg's speech at Georgetown University on Thursday, in which he described social media as a kind of "Fifth Estate" and characterized politicians' calls to take action as an attempt to restrict freedom of expression. Quoting at times from Frederick Douglass and Supreme Court jurisprudence, Zuckerberg said "we are at a crossroads" and asserted: "When it's not absolutely clear what to do, we should err on the side of free expression."

Unfortunately for Facebook, this argument holds little water. If you determine that an ad containing a fake button is non-compliant because it "[entices] users to select an answer," then you certainly should not knowingly broadcast ads that entice voters to unwittingly consume publicly-known lies -- whether they are distributed by the President or any other politician. Indeed, as one official in Biden's presidential campaign has noted, Zuckerberg's argumentation amounts to an insidious "choice to cloak Facebook's policy in a feigned concern for free expression" to "use the Constitution as a shield for his company's bottom line."

If Facebook cannot take appropriate action and remove paid political lies from its platform, the only answer must be earnest regulation of the company -- regulation that forces Facebook to be transparent about the nature of political ads and prevents it from propagating political falsehoods, even if they are enthusiastically distributed by President Trump.

Minnesota Sen. Amy Klobuchar called the impeachment hearings against Trump a "decency check" on American government.

After nearly a month of waiting, we appear to have a trial date. Several things still need to happen, but if the House transmits the articles of impeachment on Wednesday as expected, that kicks off a series of events that culminate in Trump's Senate impeachment trial beginning next Tuesday.

Asked if the trial will be over by the time Trump is slated to deliver his State of the Union address -- scheduled for February 4 -- Republican Sen. Kevin Cramer of North Dakota said, "I wouldn't bet on that myself." President Bill Clinton gave his 1999 State of the Union address in the midst of his own impeachment trial.

"I solemnly swear (or affirm, as the case may be) that in all things appertaining to the trial of the impeachment of Donald Trump, now pending, I will do impartial justice according to the Constitution and laws: so help me God."

The Senate could vote on a resolution laying out parameters for the trial.

While Trump on Monday pushed the idea of Republicans simply dismissing the charges, it is growing clear there will be a substantive trial and, depending on how the arguments go, there's a pretty good chance there will be witness testimony, too.

The question of whether to vote on dismissing the articles before the trial is clearly splitting the GOP. Sen. David Perdue, a Georgia Republican who talks to Trump and advises him regularly, said he is still interested in the motion to dismiss and hinted Republicans may need to step up and force a vote on it. But GOP Sen. Lindsey Graham of South Carolina, now a key Trump ally, said flat out that a motion to dismiss was not realistic and should not happen. Read more on the divide.

The next step is a vote in the House to appoint impeachment managers. House Speaker Nancy Pelosi says she'll announce their names Wednesday morning. That vote sets off choreographed steps that lead us to a trial.

Who will the House managers be? It's not yet clear who Pelosi will pick to deliver arguments in the Senate on behalf of the House. Adam Schiff, the House Intelligence Committee chairman, is a good bet. Other than that? We will find out Wednesday.

One key Republican to watch in terms of votes on procedural matters during impeachment is Sen. Mitt Romney of Utah. He has expressed a desire to hear from witnesses.

Sen. Tim Kaine, the Virginia Democrat pushing the war powers resolution to limit Trump's military actions in Iran, tweaked it this week to gain some more Republican support. He told reporters Tuesday he has 51 votes to pass the resolution through the Senate. He said GOP Sens. Mike Lee of Utah, Rand Paul of Kentucky, Todd Young of Indiana and Susan Collins of Maine support the resolution.

"I've got 51 declared votes on version two, on the motion to discharge, and passage. So I've got a version on which I have 51 votes, but the timing on version two is different than version one," he told reporters.

A combination of actors, from the left and the right, pushed for ever more public decisions to be made by highly educated technocratic elites living at a remove from the working class. Big corporations pushed for more decisions to be made through global trade agreements than national legislation. Ivy League liberals pushed for more critical decisions to be made by Harvard-trained jurists than prejudiced lawmakers.

“When the dust from the collapse cleared,” Lind writes, “the major institutions in which working-class people had found a voice on the basis of numbers — mass-membership parties, legislatures, trade unions and grass-roots religious and civic institutions — had been weakened or destroyed, leaving most of the nonelite population in Western countries with no voice in public affairs at all, except for shrieks of rage.”

For Lind, “the populist wave in politics on both sides of the Atlantic is a defensive reaction against the technocratic neoliberal revolution from above.” To put it this way is to ignore all the evidence that the wave was driven more by the desire to stay on top, culturally and racially, than to survive at the bottom

As Emma Green put it in The Atlantic, summing up the research: “Evidence suggests financially troubled voters in the white working class were more likely to prefer Clinton over Trump

Besides partisan affiliation, it was cultural anxiety — feeling like a stranger in America, supporting the deportation of immigrants and hesitating about educational investment — that best predicted support for Trump.”

Oligarchy is indeed a big problem. But it stands alongside a second major aspect of American life that Lind almost completely ignores: a racial and social changing of the guard

So eager is Lind to be sympathetic to populists that he begins to take their talking points at face value

“The New Class War” lacks the texture and earth and seduction of real portraiture.

Fauci also spoke about a new, more contagious variant of the coronavirus that has been detected in dozens of countries, including the U.S. "It does not appear to be more virulent, namely making people sicker or greater incidence of dying," Fauci told NBC's Chuck Todd. "Nor does it seem to elude the protection that's offered by the antibodies that are induced by the vaccine."

Many people are holding out hope that the COVID-19 vaccines will help quell the pandemic.

More than 4.2 million people have received the initial vaccination dose as of Saturday, according to the CDC. That number is far below the government's goal of having 20 million people in the U.S. vaccinated by the end of December.

"I want people to understand that the projections we were putting out were based on what we could control at the federal level. And we did deliver on 20 million doses delivered, but you're always going to have more doses allocated versus delivered. Delivered versus shots in arms," Adams said.

That approach has led to jammed phone lines, websites crashing and in some cases, people camping out in counties that took a first-come, first-served approach. In terms of what happens next with the booster shot, Zaragovia says Florida residents will have to wait for more information

While vaccinations continue, public health officials say it's still important to continue social distancing practices, including wearing masks, washing hands and watching how close people get to others.

President-elect Joe Biden opposes the death penalty and has said he will work to end its use, but as President Trump's administration accelerates the pace of federal executions in the closing days of his presidency, activists and progressive lawmakers are feeling more urgency to push Biden to act immediately upon taking office.

"Ending the barbaric and inhumane practice of government-sanctioned murder is a commonsense step that you can and must take to save lives," the lawmakers write. "We respectfully urge you to sign an executive order on Day 1 to place an immediate moratorium on the country's cruel use of the death penalty and signal your commitment to dismantle its use altogether."

The lawmakers are calling on Biden to "end the federal death penalty" on his first day in office. That's something that he wouldn't be able to do alone. "A U.S. president does not have the power to abolish the federal death penalty," Dunham said. "The only way that the federal death penalty can be abolished is an act of Congress signed by a president, or from a court decision by the U.S. Supreme Court. It's clear from the current composition of the Supreme Court that that's not going to happen, so the only way that the Biden administration would be able to end the federal death penalty would be to have some sort of bipartisan support in Congress."

Traditionally, presidential elections provide clarity on how a party sees its political future.

Today, with both presidential candidates content to make the race a referendum on Mr. Trump, questions about him have overshadowed the debates raging within both parties over how to govern a country in the midst of a national crisis.

If Mr. Biden wins, progressive Democrats are preparing to break their election-season truce, laying plans to push for liberals in key government posts, including Senator Elizabeth Warren of Massachusetts as Treasury secretary. If Mr. Biden loses, progressives will argue that he failed to embrace a liberal enough platform.

This year’s election seems likely to plunge both Republicans and Democrats into a period of disarray no matter who wins the White House.

“Nothing focuses the mind like a big election loss,” said Mr. Flake, who was one of many Republicans to retire in 2018 and who has endorsed Mr. Biden for president. “The bigger the better when it comes to the president.”

Rather than engage women or voters of color, the president expanded Republican margins with white, working-class voters, said Mr. Fleischer, a former press secretary for Mr. Bush who has come to embrace Mr. Trump after leaving his ballot blank in 2016.

Mr. Hawley argued that Republicans should embrace the populist energy of their voters by pursuing the breakup of big technology companies, voicing skepticism of free trade and making colleges more accountable for their high tuition costs.“If the party is going to have a future, it’s got to become the party of working people,” he said.

Democrats face their own divides over whether to use the moment of national crisis to push for far-reaching structural changes on issues like health care, economic inequality and climate change.

“I didn’t know at the time how much I really disagreed with Bush on some things,” Mr. Wurst said. “Look at what Mr. Trump has gotten done. I don’t like his tone, but sometimes you have to look at results.”

In Texas, a rising number of young, liberal politicians believe they can finally turn the conservative state blue by embracing a progressive platform.

No matter who wins, Democrats will be split between younger progressives and a moderate old guard. And a Republican Party redefined in President Trump’s image will start weighing where it goes next.

both parties appear destined for an ideological wilderness in the months ahead as each tries to sort out its identities and priorities.

he questions facing partisans on both sides are sweeping, and remain largely unresolved despite more than a year of a tumultuous presidential campaign.

The party is headed toward a reckoning, whatever happens in November, because you still have large segments of the party establishment that are not at all reconciled with the president’s victory in 2016,” said Senator Josh Hawley, Republican of Missouri, who is frequently mentioned as a possible 2024 contender. “These people are still very powerful in the Republican Party, and I think we’ll have a real fight for the future.”

Representative Pramila Jayapal of Washington, a co-chair of the House Progressive Caucus and an ally of Senator Bernie Sanders, said those plans were the “floor, not the ceiling” of what the liberal wing of the party plans to demand should Mr. Biden win.

“Both sides have been content to make this election about a personality,” said Brad Todd, a Republican strategist and an author of a book about the conservative populist coalition that fueled Mr. Trump’s victory in 2016. “Therefore, we’ve not had a lot of light shown on the ideological realignment that’s occurred in the country.”

Mr. Hawley argued that Republicans should embrace the populist energy of their voters by pursuing the breakup of big technology companies, voicing skepticism of free trade and making colleges more accountable for their high tuition costs.

Texas may provide a preview of these debates. As Democrats continue to make gains in the state and as the coronavirus rages there, moderate Republicans have tried to steer the state closer to the center while conservatives have tried to push Texas further right.

Yet in an increasingly polarized country, that center may be shifting.

Malala, a 2014 Nobel Peace Prize winner (at 17, she was the youngest recipient to receive the prize), began using her voice at the age of 10, standing up to the Taliban in Pakistan and advocating for the rights of girls to receive a safe, free quality education.

In the bid to lock in new rules before Jan. 20, Mr. Trump’s team is limiting or sidestepping requirements for public comment on some of the changes and swatting aside critics who say the administration has failed to carry out sufficiently rigorous analysis.

Every administration pushes to complete as much of its agenda as possible when a president’s term is coming to an end, seeking not just to secure its own legacy but also to tie the hands of any successor who tries to undo its work.

If Democrats take control of Congress, they will have the power to reconsider some of these last-minute regulations, through a law last used at the start of Mr. Trump’s tenure by Republicans to repeal certain rules enacted at the end of the Obama administration.

Two main hallmarks of a good regulation is sound analysis to support the alternatives chosen and extensive public comment to get broader opinion

Administration officials said they were simply completing work on issues they have targeted since Mr. Trump took office in 2017 promising to curtail the reach of federal regulation.

But the Trump administration is also working to fill key vacancies on scientific advisory boards with members who will hold their seats far into the next presidential term, committees that play an important role in shaping federal rule making

almost

Workers across the country deserve a chance to fully examine and properly respond to these potentially radical changes,

The Departments of Labor and Homeland Security are using a tactic known as an interim final rule, more typically reserved for emergencies, to skip the public comment period entirely and to immediately enact two regulations that put much tougher restrictions on work visas for immigrants with special skills. The rule change is part of the administration’s longstanding goal of limiting immigration.

The Homeland Security Department is also moving, again with an unusually short 30-day comment period, to adopt a rule that will allow it to collect much more extensive biometric data from individuals applying for citizenship, including voice, iris and facial recognition scans, instead of just the traditional fingerprint scan.

A third proposed new Homeland Security rule would require sponsors of immigrants to do more to prove they have the financial means to support the individual they are backing, including three years’ worth of credit reports, credit scores, income tax returns and bank records.

Unlike most of the efforts the administration has pushed, the rules intended to tighten immigration standards would expand federal regulations, instead of narrowing them

The Environmental Protection Agency, which since the start of the Trump administration has been moving at a high speed to rewrite federal regulations, is expected to complete work in the weeks that remain in Mr. Trump’s term on two of the nation’s most important air pollution rules: standards that regulate particulates and ozone emitted by factories, power plants, car exhaust and other sources.

But it is nonetheless pushing to have the rule finished before the end of Mr. Trump’s first term, limiting the period of public comment to 30 days, half the amount of time that agencies are supposed to offer.

Mr. Trump signed an executive order last year directing the Transportation Department to enact the rule within 13 months — even before it had been formally proposed.

The change was backed by the railroad and natural gas industry, which has donated millions of dollars to Mr. Trump, after construction of pipelines had been blocked or slowed after protests by environmentalists.

the proposal provoked an intense backlash from a diverse array of prominent public safety officials.

There’s plenty of blame to go around, involving Democrats as well as Republicans, but Trump in particular “recklessly squandered lives,” in the words of an unusual editorial this month in the New England Journal of Medicine. Death certificates may record the coronavirus as the cause of death, but in a larger sense vast numbers of Americans died because their government was incompetent.

As many Americans are dying every 10 days of Covid-19 as U.S. troops died during 19 years of war in Iraq and Afghanistan

The paradox is that a year ago, the United States seemed particularly well positioned to handle this kind of crisis. A 324-page study by Johns Hopkins found last October that the United States was the country best prepared for a pandemic.

Then there’s an immeasurable cost in soft power as the United States is humbled before the world.

“It’s really sad to see the U.S. presidency fall from being the champion of global health to being the laughingstock of the world,”

in terms of destruction of American lives, treasure and well-being, this pandemic may be the greatest failure of governance in the United States since the Vietnam War.

the economists David Cutler and Lawrence Summers estimate that the economic cost of the pandemic in the United States will be $16 trillion, or about $125,000 per American household — far more than the median family’s net worth.

It’s true that the Obama administration did not do enough to refill the national stockpile with N95 masks, but Republicans in Congress wouldn’t provide even the modest sums that Obama requested for replenishment. And the Trump administration itself did nothing in its first three years to rebuild stockpiles.

The Obama administration updated this playbook and in the presidential transition in 2016, Obama aides cautioned the Trump administration that one of the big risks to national security was a contagion. Private experts repeated similar warnings. “Of all the things that could kill 10 million people or more, by far the most likely is an epidemic,” Bill Gates warned in 2015.

Credit for that goes to President George W. Bush, who in the summer of 2005 read an advance copy of “The Great Influenza,” a history of the 1918 flu pandemic. Shaken, Bush pushed aides to develop a strategy to prepare for another great contagion, and the result was an excellent 396-page playbook for managing such a health crisis.

Trump argues that no one could have anticipated the pandemic, but it’s what Bush warned about, what Obama aides tried to tell their successors about, and what Joe Biden referred to in a blunt tweet in October 2019 lamenting Trump’s cuts to health security programs and adding: “We are not prepared for a pandemic.”

When the health commission of Wuhan, China, announced on Dec. 31 that it had identified 27 cases of a puzzling pneumonia, Taiwan acted with lightning speed. Concerned that this might be an outbreak of SARS, Taiwan dispatched health inspectors to board flights arriving from Wuhan and screen passengers before allowing them to disembark. Anyone showing signs of ill health was quarantined.

If either China or the rest of the world had shown the same urgency, the pandemic might never have happened.

In hindsight, two points seem clear: First, China initially covered up the scale of the outbreak. Second, even so, the United States and other countries had enough information to act as Taiwan did. The first two countries to impose travel restrictions on China were North Korea and the Marshall Islands, neither of which had inside information.

That first half of January represents a huge missed opportunity for the world. If the United States, the World Health Organization and the world media had raised enough questions and pressed China, then perhaps the Chinese central government would have intervened in Wuhan earlier. And if Wuhan had been locked down just two weeks earlier, it’s conceivable that this entire global catastrophe could have been averted.

the C.D.C. devised a faulty test, and turf wars in the federal government prevented the use of other tests. South Korea, Germany and other countries quickly developed tests that did work, and these were distributed around the world. Sierra Leone in West Africa had effective tests before the United States did.

It’s true that local politicians, Democrats and Republicans alike, made disastrous decisions, as when Mayor Bill de Blasio of New York City urged people in March to “get out on the town despite coronavirus.” But local officials erred in part because of the failure of testing: Without tests, they didn’t know what they faced.

t’s unfair to blame the testing catastrophe entirely on Trump, for the failures unfolded several pay grades below him. Partly that’s because Trump appointees, like Robert Redfield, director of the C.D.C., simply aren’t the A team.

In any case, presidents set priorities for lower officials. If Trump had pushed aides as hard to get accurate tests as he pushed to repel refugees and migrants, then America almost certainly would have had an effective test by the beginning of February and tens of thousands of lives would have been saved.

Still, testing isn’t essential if a country gets backup steps right. Japan is a densely populated country that did not test much and yet has only 2 percent as many deaths per capita as the United States. One reason is that Japanese have long embraced face masks, which Dr. Redfield has noted can be at least as effective as a vaccine in fighting the pandemic. A country doesn’t have to do everything, if it does some things right.

Trump’s missteps arose in part because he channeled an anti-intellectual current that runs deep in the United States, as he sidelined scientific experts and responded to the virus with a sunny optimism apparently meant to bolster the financial markets.

Yet in retrospect, Trump did almost everything wrong. He discouraged mask wearing. The administration never rolled out contact tracing, missed opportunities to isolate the infected and exposed, didn’t adequately protect nursing homes, issued advice that confused the issues more than clarified them, and handed responsibilities to states and localities that were unprepared to act.

The false reassurances and dithering were deadly. One study found that if the United States had simply imposed the same lockdowns just two weeks earlier, 83 percent of the deaths in the early months could have been prevented.

A basic principle of public health is the primacy of accurate communications based on the best science. Chancellor Angela Merkel of Germany, who holds a doctorate in physics, is the global champion of that approach

Trump was the opposite, sowing confusion and conspiracy theories; a Cornell study found that “the President of the United States was likely the largest driver of the Covid-19 misinformation.”

A conservative commentariat echoed Trump in downplaying the virus and deriding efforts to stay safe.

A University of Chicago study found that watching the Sean Hannity program correlated to less social distancing, so watching Fox News may well have been lethal to some of its fans.

Americans have often pointed to the Soviet Union as a place where ideology trumped science, with disastrous results. Stalin backed Trofim Lysenko, an agricultural pseudoscientist who was an ardent Communist but scorned genetics — and whose zealous incompetence helped cause famines in the Soviet Union. Later, in the 1980s, Soviet leaders were troubled by data showing falling life expectancy — so they banned the publication of mortality statistics

It was in the same spirit that Trump opposed testing for the coronavirus in the hope of holding down the number of reported cases.

Most striking, Trump still has never developed a comprehensive plan to fight Covid-19. His “strategy” was to downplay the virus and resist business closures, in an effort to keep the economy roaring — his best argument for re-election.

This failed. The best way to protect the economy was to control the virus, not to ignore it, and the spread of Covid-19 caused economic dislocations that devastated even homes where no one was infected.

Eight million Americans have slipped into poverty since May, a Columbia University study found, and about one in seven households with children have reported to the census that they didn’t have enough food to eat in the last seven days.

More than 40 percent of adults reported in June that they were struggling with mental health, and 13 percent have begun or increased substance abuse, a C.D.C. study found

More than one-quarter of young adults said they have seriously contemplated suicide

So in what is arguably the richest country in the history of the world, political malpractice has resulted in a pandemic of infectious disease followed by pandemics of poverty, mental illness, addiction and hunger.

The rejection of science has also exacerbated polarization and tribalism

An old school friend shared this conspiracy theory on Facebook:Create a VIRUS to scare people. Place them in quarantine. Count the number of dead every second of every day in every news headline. Close all businesses …. Mask people. Dehumanize them. Close temples and churches …. Empty the prisons because of the virus and fill the streets with criminals. Send in Antifa to vandalize property as if they are freedom fighters. Undermine the law. Loot …. And, in an election year, have Democrats blame all of it on the President. If you love America, our Constitution, and the Rule of Law, get ready to fight for them.

During World War II, American soldiers died at a rate of 9,200 a month, less than one-third the pace of deaths from this pandemic, but the United States responded with a massive mobilization

Yet today we can’t even churn out enough face masks; a poll of nurses in late July and early August found that one-third lacked enough N95 masks

Trump and his allies have even argued against mobilization. “Don’t be afraid of Covid,” Trump tweeted this month. “Don’t let it dominate your life.”

It didn’t have to be this way. If the U.S. had worked harder and held the per capita mortality rate down to the level of, say, Germany, we could have saved more than 170,000 lives

And if the U.S. had responded urgently and deftly enough to achieve Taiwan’s death rate, fewer than 100 Americans would have died from the virus.

“It is a slaughter,” Dr. William Foege, a legendary epidemiologist who once ran the C.D.C., wrote to Dr. Redfield. Dr. Foege predicted that public health textbooks would study America’s response to Covid-19 not as a model of A-plus work but as an example of what not to do.

And unless state and local governments get large aid from Washington, we will soon see huge layoffs of schoolteachers, firefighters and police officers.

Yet Trump and his party have come out against further aid to the unemployed and against helping beleaguered state and local governments. Instead, the party is increasingly putting all its hopes on a rapid reopening of the economy, even though that prospect terrifies health experts, who warn that it could lead to a second wave of infections and many more deaths.

Some Republicans claim that we can’t afford to keep providing a safety net, because we’re incurring too much debt. But that’s both bad economics and disingenuous. After all, soaring budget deficits haven’t stopped Trump officials from considering, yes, more tax cuts.

There’s also a pretense that the push for reopening is coming from ordinary working Americans, that it’s a populist, grass-roots demand. But the public is much more worried that we’ll reopen too quickly than that we’ll open too slowly

No, the push to ignore the health experts is a top-down thing; it’s coming from Trump and his allies, and whatever limited public support they’re getting is driven by partisanship, not populism.

In the early stages of this pandemic, Trump and the right in general downplayed the threat because they didn’t want to hurt stock prices. Now they’re pushing for a premature end to containment because they imagine that it will boost stocks again.

So Trump and his party want to go full speed ahead with reopening no matter how many people it kills. As I said, their de facto position is that Americans must die for the Dow.

Krebs led an effort to improve communication between state and local election jurisdictions about threat activity and election security best practices.

"This was a secure election," Krebs said. "That is a success story. That is something everyone in the administration should be proud of. That's the story I feel we should be telling now."

Instead, Krebs' former agency has spent much of the past few weeks batting down baseless claims by the president and his legal team about the security of the vote.

CISA launched a website dubbed Rumor Control, aimed at debunking election disinformation spreading on social media.

"We certainly saw throughout that a number of people associated with the campaign, were pushing certain narratives that we fundamentally knew to be false," Krebs said, while listing a number of claims about which Trump himself has tweeted. "We knew that it was important to get this information out there."

Going forward, Krebs said he is most worried about how misinformation about elections has "seeped into the mainstream" and what that will mean for people's confidence in results.

One of the easiest ways government can improve people's opinions of voting, he added, is to invest more resources and money into election administration.

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

Attempting to ease tensions with China to make cooperation on global public health possible won’t work, partly because Beijing cannot credibly commit to being more transparent and cooperative in the future.

Xi did not want to facilitate an international response to COVID-19 that could have attributed blame to China or isolated it through travel restrictions, either of which might have damaged the regime’s domestic legitimacy. Instead, Xi leveraged the pandemic to his advantage: China’s suppression of the virus became a matter of national pride, held up by Beijing in sharp contrast to the experience of the United States.

But in case cooperation fails, it must have a backup plan to rally allies and partners to provide a much greater share of global public goods, even if that means shouldering more of the costs.

as a number of U.S. embassy officials told the foreign policy analyst Colin Kahl and me for our book Aftershocks, this team’s cooperation with the Chinese government became more challenging as U.S.-Chinese rivalry intensified, largely because of China’s actions.

When COVID-19 hit, the Chinese Communist Party (CCP) maintained near-absolute secrecy. All channels of communication between Beijing and Washington went silent, as they did between Beijing and other governments. Chinese leaders sought to conceal vital information about the emerging epidemic in China from the rest of the world, even attempting to prevent Chinese scientists from sharing the genetic sequence of the virus with scientists in other countries.

It is impossible to say for certain why the Chinese government behaved the way it did, but secrecy and control make sense in light of what the vast majority of China experts believe to be Xi’s top priority: regime survival.

For China’s leaders, the pandemic revealed the inexorable decline of the West, confirmed Beijing’s power and capabilities, and created more latitude for the CCP to do as it wished.

according to the UN, the pandemic could force a total of 490 million people into poverty—defined as the loss of access to clean water, adequate food, or shelter—pushing the global poverty rate to around seven percent by 2030, compared with the pre-pandemic target of three percent. 

Contrary to popular belief, some senior Trump administration officials grasped the national security threat posed by the virus faster than their European counterparts did. Top officials in the National Security Council began focusing on the pandemic in early January, just days after news of the outbreak in Wuhan, China, became public.

ven though Pottinger and other NSC officials were wise to the danger, they ultimately failed to persuade Trump to make the necessary preparations to deal with the pandemic when it inevitably reached the United States. 

As the administration began to formulate its response, those who favored a more comprehensive public health approach both at home and abroad were excluded or marginalized at crucial moments. The result was that the Trump administration focused more on holding China responsible for the outbreak and reducing U.S. reliance on Beijing than on the minutiae of global public health policy or the hard work of rallying the world to tackle the pandemic.

the pandemic and China’s response to it helped unify the administration behind a more comprehensive strategy to push back against Beijing. Between March 2020 and the end of the year, the senior official said, the United States put in place more containment measures than it had in the previous three years, including restrictions on Chinese technology firms, sanctions on Chinese officials, looser regulations on diplomatic contacts with Taiwan, and recognition of the repression in Xinjiang as a genocide. In this sense, the pandemic was a pivotal moment in the U.S.-Chinese rivalry. 

Competition between the two countries overwhelmed everything else, including U.S. cooperation with allies on the pandemic, leaving a global leadership vacuum that no one could fill.

The EU tried to step up by increasing funding for the WHO and for COVAX, the global initiative to share vaccines, but it never came close to organizing a global response. China’s assertive foreign policy, and its attempts to use pandemic assistance to advance its interests, aggravated European leaders and convinced them to harden their positions toward China throughout the course of 2020. 

During this period, there was hardly any international cooperation on vaccine development or distribution, no coordination on travel restrictions or the distribution of medical supplies, and limited cooperation on achieving a cessation of hostilities in conflict zones

The economic disruption caused by COVID-19 devastated low-income countries, which received little in the way of international assistance. Especially hard hit were countries, such as Bangladesh, that had made significant development gains in the last two decades and were propelling themselves into the lower tier of middle-income economies.

The United States needs a strategy to address transnational threats under the conditions of great-power competition. It must aim to cooperate with rivals, especially China, to prepare for future pandemics and to tackle climate change

Pandemics are not the only transnational threat that promises to intensify great-power rivalry and diminish the prospects for much-needed cooperation. Climate change could do the same.

Rather than unite the world around a common purpose, climate change is likely to deepen competition between major powers, especially as the transition away from fossil fuels creates economic winners and losers.

Countries that aggressively decarbonize could place sanctions and other trade restrictions on countries that do not, leading to counterresponses and new trade wars.

the impediments to cooperation between Europe and China on climate change “are becoming higher” and warn that “decision-makers must not underestimate the highly competitive aspects of how China is changing its energy production and consumption.” 

The United States and Europe will both compete with China for access to raw materials and in developing the technology needed to make their economies carbon neutral: magnets, batteries, high-performance ceramics, and light-emitting diodes, among other things

even if the U.S. government remains broadly aligned with Europe on climate policy, the Europeans could still become disaffected if Congress blocks meaningful climate action, such as commitments to cut carbon emissions or invest in clean technology. This, in turn, could diminish Europe’s willingness to help uphold the U.S.-led international order.

If, on the one hand, they mean softening U.S. rhetoric without conceding much of substance to China, they would do well to look to Europe, where governments were much more inclined than the Trump administration to cooperate with China, but China did not take them up on the offer.

If, on the other hand, they mean unilaterally making major geopolitical concessions to China—on its territorial acquisitions in the South China Sea, for instance, or the status of Taiwan—the United States would not only pay an extremely high price but also likely embolden Beijing further without actually securing cooperation on pandemics or climate change beyond what Beijing has already offered.

There is no getting around strategic competition with Beijing: it is deeply embedded in the international order, mainly because China seeks to expand its sphere of influence in Asia at the expense of the United States and its allies, which are in turn committed to thwarting Beijing’s plans.

The United States and China are also engaged in what Jake Sullivan, Biden’s national security adviser, recently called “a competition of models.” China is seeking to make the world safe for the CCP and to demonstrate the effectiveness of its system. This entails pushing back against what it sees as pressure from liberal democratic countries that could thwart its objectives. For its part, the United States worries about the negative externalities of Chinese authoritarianism, such as censorship of international criticism of Beijing or the export of its tools of repression to other countries.

The United States also worries about what would happen to the military balance of power if China secured an enduring advantage in key technologies.

Even in diplomacy, friction will be endemic to the U.S.-Chinese relationship and will affect the broader international order for the foreseeable future. Outright confrontation can be avoided—but competition cannot. 

This competition places real limits on cooperation. Take the arena of global public health: many studies on how to improve pandemic preparedness call on world leaders to dramatically strengthen the WHO, including by giving it the same power to enforce international health regulations as the International Atomic Energy Agency enjoys with nuclear nonproliferation rules

The problem is getting every government to agree to a universally applicable mechanism for sanctions or some other enforcement mechanism. China will not agree to any reform that would involve intrusive inspections of its scientific research facilities.

The need for cooperation on transnational threats must change how the United States competes with China—not whether it competes.

U.S. officials should not give up on China entirely; instead, they should make a good-faith effort to work with Beijing, both bilaterally and in multilateral settings. Recognizing that there are strict limits on U.S.-Chinese cooperation is not the same as saying that no cooperation is possible.

the real challenge is determining what to do when cooperation with China and other rivals falls short of what is required. The United States needs a backup plan to tackle shared challenges through coalitions of the willing.

When it comes to pandemic preparedness, this means fully supporting the WHO (including by pressing for needed reforms) but also forging a coalition of like-minded states: a global alliance for pandemic preparedness that would regularly convene at the head-of-state level and work alongside nongovernmental organizations and the private sector.

Crucially, whenever the WHO declared an international public health emergency, alliance members would coordinate on travel and trade restrictions, as well as on public messaging and financial penalties and sanctions. Those penalties and sanctions would be aimed at those states that failed to provide sufficient access to or fully cooperate with the WHO. The alliance would support, not supplant, the WHO.

Sustained, managed competition with China could potentially help the United States build bipartisan support for investments in clean technology that would prevent Beijing from gaining an enduring advantage in this area.

ut the United States and the European Union will also need to build coalitions of the willing to deal with the international security consequences of accelerated climate change, such as extreme weather events that threaten large numbers of people, and to address the foreign policy dimensions of climate action, including managing the risk that a shift away from fossil fuels could destabilize countries and regions that are dependent on oil exports.

Cooperation across this divide should always be the first choice in times of shared crisis, but as the COVID-19 pandemic has demonstrated, the U.S.-led constellation must always have a backup plan. It did not have one in 2020. It needs one for the next crisis

“It is genius for the current consumer culture,” Christine Whelan, a clinical professor of consumer science at the University of Wisconsin at Madison, told me. “It encourages and then meets the need for the thing, so we then continue on the hedonic treadmill: Buy the latest thing we want and then have it delivered immediately and then buy the next latest thing.”

With traditional retail, “there’s the friction of having to go to the store, there’s the friction of will the store have it, there’s the friction of carrying it,” Whelan said. “There’s the friction of having to admit to another human being that you’re buying it. And when you remove the friction, you also remove a lot of individual self-control. The more you are in the ecosystem and the easier it is to make a purchase, the easier it is to say yes to your desire rather than no.”

“It used to be that being a consumer was all about choice,”

But now, “two-thirds of people start their product searches on Amazon.

Prime discourages comparison shopping—looking around is pointless when everything you need is right here—even as Amazon’s sheer breadth of products makes shoppers feel as if they have agency.
