Climate change denial: a history

“Climategate” was the latest in a long line of baseless, right-wing attacks on scientists.

On 31 March, the House of Commons science and technology committee, charged with investigating potential wrongdoing by Phil Jones and his colleagues at the University of East Anglia (UEA), concluded that there was "no case to answer" on the allegation of scientific dishonesty. An international panel commissioned by UEA in consultation with the Royal Society agreed. Yet, after a media frenzy back in December over what was inevitably called "Climategate", the vindication of the climate scientists has received very little coverage at all.

Vindication is not as sexy as accusation, and many people are still suspicious. After all, some of those emails, taken out of context, sounded damning. But what they show is that climate scientists are frustrated, because for two decades they have been under attack.

In the late 1970s, scientists first came to a consensus that global warming was likely to result from increasing greenhouse gases released by burning fossil fuels. This idea had been around since the turn of the century, but the development of computer models now made it possible to make quantitative predictions. Almost immediately, a small group of politically connected and conservative scientists began to question these conclusions. As the scientific evidence got stronger, their attacks became more unprincipled. They used data selectively and often misrepresented what was being published in the scientific literature.

In 1992, world leaders gathered in Rio de Janeiro to sign the United Nations Framework on Climate Change. President George W Bush promised to translate the written document into "concrete action". Three years later, the Intergovernmental Panel on Climate Change (IPCC) declared that the human impact on the earth's climate was no longer a prediction, but an observed fact. That's when things started to get ugly.

In the early 1990s, a group of sceptics claimed that Roger Revelle, one of the first climate scientists, had changed his mind about global warming and no longer believed it was a serious problem. The claim was repeated through several news outlets, including the Washington Post. When a graduate student named Justin Lancaster - who had worked closely with Revelle before his death in 1991 - tried to insist that Revelle had not changed his view, he was sued for libel. Lancaster was obliged to settle out of court. The charges were repeated again and again, and echo on the net today.

In 1996, when the IPCC released its second assessment report, stating that the human impact on climate was "discernible", a fossil-fuel-industry-funded group called the Global Climate Coalition accused the IPCC author Benjamin Santer of making unauthorised changes to make global warming appear more certain than it was. The following year, Frederick Seitz, chairman of the libertarian George C Marshall Institute, repeated the charges in the Wall Street Journal in an op-ed piece headlined "A major deception on global warming".

Letters were sent to US members of Congress demanding an investigation and then from Congress to the US energy department, demanding that it withdraw funding from the laboratory that employed Santer.

Massive attack

Had Santer made unauthorised changes to the IPCC report? No: his changes were made in response to peer review. He was doing what every scientist is expected to do - and what IPCC rules required him to do - accepting criticism and using it to make the science clearer. Frederick Seitz was a former president of the National Academy of Sciences, so it was not plausible that he did not know about the peer-review process.

In 2007, the claims were repeated in Unstoppable Global Warming: Every 1,500 Years, a book whose premise is that "human-emitted CO2 has played only a minor role" in contributing to global warming. The authors are Dennis Avery and Fred Singer, a physicist with a track record of challenging scientific evidence who had taken part in the previous attack on Santer.

Both the IPCC and Santer's co-authors took considerable pains to set the record straight, denying that Santer had done anything wrong. Yet, in their book, Avery and Singer reassert that "scientific reviewers discovered that major changes had been made 'in the back room' after they had signed off on the science chapter's contents" and that "Santer single-handedly reversed the 'climate science' of the whole IPCC report". The idea that any one individual could reverse the entire IPCC process is absurd, and yet, like the "Revelle changed his mind" claim, it remains on the internet today.

Climate scientists have been subjected to repeated attacks of this kind. In 2005, Congressman Joe Barton of Texas demanded that Professor Michael Mann, director of the Earth System Science Centre at Pennsylvania State University, produce a huge volume of paperwork relating to his research. In February, Senator James Inhofe of Oklahoma accused a dozen climate scientists of criminal violations of federal law, based on alleged evidence contained in the UEA emails. Recently, Virginia's attorney general, Ken Cuccinelli, went after Mann again, asking for the University of Virginia to produce thousands of pages of documents relating to Mann's work when he taught there.

We, too, have been objects of attack. When one of us (Naomi Oreskes) published a review in the journal Science of the book The Republican War on Science, in which we noted some connections not pursued in that book, Science was threatened with a lawsuit unless it published a rebuttal. (We supplied documents, Science held firm, and the threat went away.)

Blaming scientists for speaking truth to power is an old story. Scientists have long recognised that both the government and public can be
reluctant to accept scientific evidence leading to discomfiting conclusions. In 1949, when the USSR detonated its first atomic bomb, the US had to face the reality that it had lost its monopoly on nuclear weapons. Scientists had been warning of this since 1945, but the success of their predictions did not increase their standing. When they then said that any attempt to stay ahead of the Soviets by building the H-bomb would only speed up the arms race, they were accused of being disloyal. As Harold Urey, who won the Nobel Prize in Chemistry in 1934, wrote: "Because we [scientists] told disagreeable truths, we have even been accused of wishing to give up our progress because we are impractical dreamers or plain traitors."

What is most disagreeable to many "resistors" of global warming is the fear of climate change being used as a warrant for heavy-handed government intervention. There is a parallel with 1949: fear of the Soviet Union then was not fear of a potential invasion, but that the Soviets would export communism to Europe, from where it might spread to the US.

Today, US conservatives and right-wing com­mentators are red-baiting once again. In December, the columnist Charles Krauthammer alleged that "with socialism dead . . . the left was adrift until it struck upon a brilliant gambit: metamorphosis from red to green". Patrick J Michaels, some-time policy scholar at the libertarian Cato Institute, labelled plans for a cap-and-trade system to control greenhouse gases as "Obamunism". The irony is that in 1990, Bush installed a cap-and-trade regime to reduce acid rain because it was an acceptably market-based mechanism. Yet now, when Congress is finally taking the model seriously, conservatives call it communism by other means.

Market failure

“Climategate", and the wider attacks on climate science, had nothing to do with the science itself, and neither did the entire earlier history of global-warming denial we have studied. Scientists have just been an easy target. The real issue is the politics of defending the free market.

Since the mid-1990s, the fossil-fuel industry has made common cause with old cold warriors, maverick scientists and conservative and libertarian think tanks to undermine climate science. The obvious reason is that climate change is what Nicholas Stern calls "the greatest and widest-ranging market failure ever seen". If the free market has failed, then governments will need to act. And that is precisely what various constituencies, from Inhofe to Cuccinelli and a host of think tanks, do not want. It was also what Seitz and his colleagues didn't want. These scientists were passionately anti-communist, and viewed any form of government regulation as a step towards socialism.

No wonder we see the rise of McCarthyite tactics today: the stakes, at least in some people's eyes, are the same. But what these people seem to have forgotten from the 1950s is that McCarthyism didn't just destroy the careers of many innocent people: in the end, it destroyed Joe McCarthy, too.

The Brexit odd squad

The Brexiters are resilient and have the support of some unlikely foreign allies. Can they really topple the political establishment and lead Britain out of the European Union?

Look at the troops arrayed on the Leave and the Remain sides in the June referendum and you might think that our continued membership of the European Union is assured. On the side of staying in the EU are Britain’s four living prime ministers, the International Monetary Fund, the Treasury, most members of the Labour and Liberal Democrat parties, the Trades Union Congress, the Confederation of British Industry, the governor of the Bank of England, the head of the NHS, Britain’s three largest trade unions and the US president. Leave has Boris Johnson, Nigel Farage and the contested ghost of Margaret Thatcher.

Yet few expect the final result of Britain’s In/Out referendum to be as asymmetric as that roll-call would suggest. At the top of the pro-EU campaign Britain Stronger in Europe, there is no doubt: it could lose.

So what – and who – is responsible for the unlikely appeal of Brexit’s “odd squad”? And how do they work together when their side is so fractious and its big personalities seem so uninterested in teamwork?

The story begins on the morning of 20 February, when David Cameron summoned his cabinet to announce the results of his EU renegotiation and ask his ministers to support Britain’s continued membership of the Union. Those who did left by the front door; the six dissidents were asked to leave by the tradesman’s entrance.

Nipping out the back were the full cabinet members Iain Duncan Smith, Michael Gove, Chris Grayling, Theresa Villiers and John Whittingdale, plus the employment minister, Priti Patel, who has the right to attend cabinet meetings. They soon reconvened at Vote Leave’s headquarters, a nondescript tower block in Westminster, where they posed with a giant sign bearing the campaign’s slogan “Vote Leave, take control” – a sight more reminiscent of a group of local councillors vowing to protect a bus lane than the upper reaches of the British political class.

Then again, the cabinet Leavers are not, on the whole, an impressive bunch. Villiers and Grayling were among the casualties of the formation of the coalition government in 2010, moving from their briefs to make way for Lib Dems, and both had to be content with junior posts until the 2012 reshuffle. Since then, Villiers has been a competent if uninspiring operator in Northern Ireland. Grayling was widely held to be a failure at the Ministry of Justice and now serves as Leader of the House of Commons, historically the antechamber between full cabinet rank and the wilderness.

As for Whittingdale, he is that rare creature in Whitehall: a secretary of state for culture, media and sport who does not regard the post as a stepping stone to bigger things. As the recent white paper on the future of the BBC showed, the golden thread of his thinking is scepticism: towards the EU, the BBC and regulation of the press. He was Margaret Thatcher’s last political secretary in Downing Street and, after becoming an MP in the 1992 election, he set up meetings between the former prime minister and his fellow new boys from the 1992 intake – meetings that John Major blamed for fanning the flames of Eurosceptic rebellion in the dog days of his premiership.

Priti Patel also has impeccable Eurosceptic credentials. She cut her teeth as a press officer to the Referendum Party, set up in a doomed attempt to secure an In/Out referendum in 1997. Following William Hague’s election as Tory leader and the adoption of complete hostility towards the single currency, she joined the Conservative Party, becoming an MP in 2010.

She is best known for contributing to Britannia Unchained, a series of essays by Patel and four of her fellow 2010-ers (including Dominic Raab, widely expected to run for the Tory leadership next time). The book was intended to provide the intellectual ballast for a revivified Thatcherism, though the only part that attracted headlines was the claim that British workers were “among the worst idlers in the world”.

This dubious crew of ministerial heavyweights has grown marginally more likeable since Duncan Smith’s resignation as work and pensions secretary. Yet it is not his six-year tenure as a minister but his two-year stint as Tory leader that has left the biggest mark on the Brexit debate, with his former hires among the loudest advocates for a Leave vote – including the founding editor of ConservativeHome, Tim Montgomerie, now at Gove’s old newspaper the Times. (In the unhappiest periods of Cameron’s first term, when the Prime Minister was frequently criticised by Montgomerie in that newspaper, Cameroons would mutter about the irony that one of their sharpest critics had served as chief of staff to the least successful leader of the Conservative Party in its history.)

As for Michael Gove, though he is loved by lobby journalists, he remains a hate figure in the country at large and particularly among teachers, as a result of his belligerent tactics during his time as secretary of state for education.

The last of the senior Brexit-supporting Tories didn’t leave through the back door that morning because he hadn’t yet declared his position. That came the next day, in a media scrum outside his home in Islington, north London.

The former mayor of London Boris Johnson is still Britain’s most popular politician, surviving crises and scandals that would have left others dead in the water. He is also the only politician whom the Remain campaign truly fears. But Johnson is not a wholly congenial presence among Britain’s Brexiters. Although he is a far more adept planner than his dishevelled appearance – or his paper-thin record at City Hall – would suggest, he can be difficult to manage. His  weekly Telegraph column has largely been turned to cheerleading for Brexit but Vote Leave’s biggest gun doesn’t always point in the direction its chief strategists would like.

During Barack Obama’s visit to the UK in April, Johnson became embroiled in a war of words in which he suggested that the president had an ancestral dislike of Britain because of his “part-Kenyan” heritage. Having made this racially charged argument in the Sun, he extended the story needlessly by giving a similarly robust interview to the Daily Mail, much to the frustration of staffers at Vote Leave.

So there you have it. An unpopular firebrand, an unsuccessful former Tory leader, four relative nonentities and a blond bombshell who is considered clever but uncontrollable. It is less a huddle of Big Beasts than a grotesque menagerie – and these are among the sensible, mainstream voices on the Leave side. The other politicians who can get on to the Sunday shows to talk Brexit include Nigel Farage, who is adored by the four million people in Britain who voted Ukip in last year’s general election – and hated by the remaining 42 million. Yet he is a national treasure compared to George Galloway, formerly of Labour, who secured just 37,000 votes in the mayoral election. An unkind observer might say that none of the Brexit-backing politicians can stop traffic: half of them because they are unknown and the other half because most people would quite like to run them over.

There are also few compelling figures from business, sport, entertainment and science backing Brexit. Ian Botham is a rare celebrity Outer. “Cricket is a game where you achieve the greatest success when you are confident in your own ability to go out and stand proud,” he wrote in the Sunday Times. “Britain has that spirit.” In April, a slew of acts withdrew from a gig in Birmingham after finding out that it was organised by Leave.EU. Only Phats & Small, whose last hit was in 1999, refused to pull out.

Then there’s the infighting. To give just one example of the ongoing civil war, Vote Leave – the officially recognised campaign group for Brexit – believes Farage is so toxic to its cause that it regards his invitation to appear in a TV discussion alongside Cameron as an establishment stitch-up. “ITV has effectively joined the official In campaign,” said a Vote Leave statement to journalists on 11 May, written by Dominic Cummings, the campaign’s director. “There will be consequences for its future – the people in No 10 won’t be there for long.”

***

In the light of all this, why are the pro-Europeans so worried? Many feel that the current campaign is beginning to remind them of a nightmare year: 2011, when Britain voted decisively to reject electoral reform by moving from first-past-the-post to the Alternative Vote (AV). Around the time of the 2010 general election, polls had shown that Britain was in favour of the change by a 27-point margin. But on 5 May 2011, more than two-thirds of voters said No to AV, which ended up more than 35 points ahead.

What undid the Alternative Vote was a ruthlessly effective campaign against it – one that was almost completely fact-free. No2AV focused relentlessly on the cost of a new voting system; poster after poster made reference to its illusory price tag of £250m. “He needs bulletproof vests,” intoned one illustrated with a picture of a soldier, “NOT an alternative voting system.” Another came with a picture of a baby: “She needs a new cardiac facility, NOT an alternative voting system.”

As one veteran of the pro-AV campaign recalled recently: “It was impossible to fight. How do you repudiate it without repeating it? We never found a way.”

That appeal to economic interests was so powerful that Vote Leave has come up with a similarly memorable figure: the £350m weekly cost of Britain’s EU membership. This has been debunked by fact-checkers such as Full Fact, which estimates that the UK pays roughly £9.8bn a year once money back is taken into account. Regardless, Vote Leave keeps quoting the figure – and no wonder, because the chief executive of Vote Leave is also the architect of No2AV’s crushing victory: a 38-year-old LSE graduate called Matthew Elliott.

Despite Vote Leave’s anti-politics flavour, Elliott is a Westminster insider and well connected in the wonk world. He is the founder of the Taxpayers’ Alliance, the most high-profile of a close network of think tanks that are a proving ground for a rising generation of right-wingers. The Taxpayers’ Alliance, the Institute of Economic Affairs and the Adam Smith Institute together form what one alumnus jokingly calls a “Sorbonne for neoliberals”.

Much of Vote Leave’s staff is drawn from another Elliott creation: Business for Britain. The group was set up ostensibly to lobby for David Cameron to renegotiate Britain’s membership of the EU but was in reality designed as a Leave campaign in utero. Accordingly, many of its early recruits have ended up moving across.

Elliott is regarded as having a keen eye for talent and for being generous with his time. At each organisation where he has worked, he has taken care to bring on promising protégés. Alumni of the Elliott school include Susie Squire, who spent two years at the heart of Cameron’s administration as press secretary; Nick Pickles, head of UK public policy at Twitter; and Dylan Sharpe, the combative head of public relations at the Sun. Most of his favourite employees have three things in common: libertarian politics, a cut-throat instinct and loyalty to him personally. Those who have worked for Elliott largely speak highly of him.

The same cannot be said for the second leading player in Vote Leave who has the Remain side worried: Gove’s former henchman Dominic Cummings. David Laws – who, as a junior minister, worked closely with Cummings when he was at Gove’s Department for Education – describes him as a “grade-A political Rottweiler”. “As well as being bright,” Laws writes in his memoirs, “Dom Cummings was also blunt, rude, impatient and tactless.” According to friends of both, without Cummings’s encouragement, Gove would have been a mostly silent presence in the Leave campaign because of his close friendship with Cameron.

The former special adviser’s commitment to anti-Europeanism is a long-held one – his first job in politics was at Britain for Sterling, which lobbied against Britain joining the European single currency in the 1990s. Thereafter, he worked for Iain Duncan Smith during his brief and unhappy leadership. A former staffer from that time remembers him as an “abrasive presence”.

After Duncan Smith’s removal as Tory leader, Cummings retreated to his native Durham, where he helped to engineer victory for the No side in the referendum on whether to give the north-east its own devolved assembly. It was the tactics used in that referendum – an endless focus on costs, coupled with personal attacks on the credentials of the Yes side – which were taken on and extended by Elliott during the AV contest. Those tactics are once again on display in this referendum.

That partly explains why, on the Remain side, Cummings is respected and feared in equal measure. Yet his confrontational approach often proves his undoing: for instance, he understood the importance of giving a cross-party sheen to Vote Leave (not least to secure the official campaign designation), yet his conduct led to the departure of the Eurosceptic Labour MP Kate Hoey. “We live in a world where people get things by being nice to each other,” reflects a former colleague of Cummings, “and Dom doesn’t really work like that.”

Hoey’s walkout set the ball rolling on another, less dramatic exit: John Mills, Labour’s largest private individual donor and a Brexiter of many years’ standing. He feared the Vote Leave brand had become irrevocably Conservative. (Unlike Hoey, Mills remains on speaking terms with Vote Leave.)

Friends say that, for Elliott, who has been “planning this [campaign] for some time”, Cummings’s disposition is a price worth paying for his tactical nous. It was Cummings who was the architect of Vote Leave’s two-pronged strategy: claiming that the money we now pay to the EU could go towards the NHS, and suggesting that Brexit will allow us to cut immigration by “regaining control of our borders”.

The perceived cut-through of the latter message with older Labour voters was behind Vote Leave’s big tactical gamble. On 8 May, an official statement by the campaign declared that leaving the EU would also entail leaving the single market.

That decision is unlikely to find favour with big businesses that rely on international trade but it does allow Vote Leave to make strong and unambiguous claims about cutting immigration. If we are outside the European Union but inside the single market (as Norway is), we would have to accept free movement of labour. If we leave the single market, however, we could introduce a points-based entry system, or even finally achieve Cameron’s otherwise impossible cap on net migration.

Upset business but win over small-C conservative voters: it’s a big risk for the Brexiters to take. It represents a throw of the dice by Cummings, who sidelined Nigel Farage precisely in order to minimise the campaign’s focus on immigration. But with the vote scheduled to take place on 23 June and a repeat of last year’s refugee crisis in the Mediterranean looming, security and borders are likely to be at the forefront of voters’ minds. For all that those on the Brexit side have denounced Cameron for running a repeat of “Project Fear”, they know that they have to make change less terrifying than maintaining the status quo.

***

In their quest to take Britain out of the EU, the Brexiters have a simple, if high-stakes, strategy. They want to appear to be the underdogs (hence their repeated complaints about the government’s £9m pro-EU leaflet) and as a scrappier, grass-roots campaign taking on the might of the establishment. Naturally, this image doesn’t reflect an unvarnished truth: the press has been largely onside and senior editors and columnists are very willing to take Vote Leave’s calls.

There is also no concern about keeping the lights on. Arron Banks, the insurance magnate who bankrolled Ukip at the 2015 general election, might have refused to fund Vote Leave after it triumphed over his favoured vehicle, Leave.EU – he has called Matthew Elliott “Lord Elliott of Loserville” and threatened to sue the Electoral Commission for naming Vote Leave the official voice of Brexit – but insiders say that the campaign’s financial position is nothing to worry about.

If Vote Leave wins, it will have scored an extraordinary victory – and, it should be noted, defied the hopes of most of our allies in the rest of the world. The politicians backing Britain’s continued membership of the EU include not just Barack Obama but his likely successor, Hillary Clinton, as well as the prime ministers of Canada, New Zealand and Australia.

There is a vanishingly small number of international politicians who back Brexit. Like the inner core of Vote Leave, they are overwhelmingly drawn from the right-wing fringe – US Republicans such as Ted Cruz and Donald Trump and the French National Front leader, Marine Le Pen, who, unhappily for the Brexiters, is expected to visit Britain to support their case.

The only foreign leader who seriously supports a British Leave vote in June is a man praised by Nigel Farage and whose country Dominic Cummings spent several years working in: Vladimir Putin, who, as far as British voters are concerned, is even more toxic than Farage, Galloway or Gove.

When Britain’s odd squad looks abroad for allies, its options are few – but this ragtag collective is far from beaten.
