Has global warming really stopped?

Mark Lynas responds to a controversial article on newstatesman.com which argued global warming has s

On 19 December the New Statesman website published an article which, judging by the 633 comments (and counting) received so far, must go down in history as possibly the most controversial ever. Not surprising really – it covered one of the most talked-about issues of our time: climate change. Penned by science writer David Whitehouse, it was guaranteed to get a big response: the article claimed that global warming has ‘stopped’.

As the New Statesman’s environmental correspondent, I have since been deluged with queries asking if this represents a change of heart by the magazine, which has to date published many editorials steadfastly supporting urgent action to reduce carbon emissions. Why bother doing that if global warming has ‘stopped’, and therefore might have little or nothing to do with greenhouse gas emissions, which are clearly rising?

I’ll deal with this editorial question later. First let’s ask whether Whitehouse is wholly or partially correct in his analysis. To quote:

"The fact is that the global temperature of 2007 is statistically the same as 2006 as well as every year since 2001. Global warming has, temporarily or permanently, ceased. Temperatures across the world are not increasing as they should according to the fundamental theory behind global warming – the greenhouse effect. Something else is happening and it is vital that we find out what or else we may spend hundreds of billions of pounds needlessly."

I’ll be blunt. Whitehouse got it wrong – completely wrong. The article is based on a very elementary error: a confusion between year-on-year variability and the long-term average. Although CO2 levels in the atmosphere are increasing each year, no-one ever argued that temperatures would do likewise. Why? Because the planet’s atmosphere is a chaotic system, which expresses a great deal of interannual variability due to the interplay of many complex and interconnected variables. Some years are warmer and cooler than others. 1998, for example, was a very warm year because an El Nino event in the Pacific released a lot of heat from the ocean. 2001, by contrast, was somewhat cooler, though still a long way above the long-term average. 1992 was particularly cool, because of the eruption of a large volcano in the Philippines called Mount Pinatubo.

‘Climate’ is defined by averaging out all this variability over a longer term period. So you won’t, by definition, see climate change from one year to the next - or even necessarily from one decade to the next. But look at the change in the average over the long term, and the trend is undeniable: the planet is getting hotter.

Look at the graph below, showing global temperatures over the last 25 years. These are NASA figures, using a global-mean temperature dataset known as GISSTEMP. (Other datasets are available, for example from the UK Met Office. These fluctuate slightly due to varying assumptions and methodology, but show nearly identical trends.) Now imagine you were setting out to write Whitehouse’s article at some point in the past. You could plausibly have written that global warming had ‘stopped’ between 1983 and 1985, between 1990 and 1995, and, if you take the anomalously warm 1998 as the base year, between 1998 and 2004. Note, however, the general direction of the red line over this quarter-century period. Average it out and the trend is clear: up.

Note also the blue lines, scattered like matchsticks across the graph. These, helpfully added by the scientists at RealClimate.org (from where this graph is copied), partly in response to the Whitehouse article, show 8-year trend lines – what the temperature trend is for every 8-year period covered in the graph.

You’ll notice that some of the lines, particularly in the earlier part of the period, point downwards. These are the periods when global warming ‘stopped’ for a whole 8 years (on average), in the flawed Whitehouse definition – although, as astute readers will have quickly spotted, the crucial thing is what year you start with. Start with a relatively warm year, and the average of the succeeding eight might trend downwards. In scientific parlance, this is called ‘cherry picking’, and explains how Whitehouse can assert that "since [1998] the global temperature has been flat" – although he is even wrong on this point of fact, because as the graph above shows, 2005 was warmer.

Note also how none of the 8-year trend lines point downwards in the last decade or so. This illustrates clearly how, far from having ‘stopped’, global warming has actually accelerated in more recent times. Hence the announcement by the World Meteorological Organisation on 13 December, as the Bali climate change meeting was underway, that the decade of 1998-2007 was the “warmest on record”. Whitehouse, and his fellow contrarians, are going to have to do a lot better than this if they want to disprove (or even dispute) the accepted theory of greenhouse warming.

The New Statesman’s position on climate change

Every qualified scientific body in the world, from the American Association for the Advancement of Science to the Royal Society, agrees unequivocally that global warming is both a reality, and caused by man-made greenhouse gas emissions. But this doesn’t make them right, of course. Science, in the best Popperian definition, is only tentatively correct, until someone comes along who can disprove the prevailing theory. This leads to a frequent source of confusion, one which is repeated in the Whitehouse article – that because we don’t know everything, therefore we know nothing, and therefore we should do nothing. Using that logic we would close down every hospital in the land. Yes, every scientific fact is falsifiable – but that doesn’t make it wrong. On the contrary, the fact that it can be challenged (and hasn’t been successfully) is what makes it right.

Bearing all this in mind, what should a magazine like the New Statesman do in its coverage of the climate change issue? Newspapers and magazines have a difficult job of trying, often with limited time and information, to sort out truth from fiction on a daily basis, and communicating this to the public – quite an awesome responsibility when you think about it. Sometimes even a viewpoint which is highly likely to be wrong gets published anyway, because it sparks a lively debate and is therefore interesting. A publication that kept to a monotonous party line on all of the day’s most controversial issues would be very boring indeed.

However, readers of my column will know that I give contrarians, or sceptics, or deniers (call them what you will) short shrift, and as a close follower of the scientific debate on this subject I can state without doubt that there is no dispute whatsoever within the expert community as to the reality or causes of manmade global warming. But even then, just because all the experts agree doesn’t make them right – it just makes them extremely unlikely to be wrong. That in turn means that if someone begs to disagree, they need to have some very strong grounds for doing so – not misreading a basic graph or advancing silly conspiracy theories about IPCC scientists receiving paycheques from the New World Order, as some of Whitehouse’s respondents do.

So, a mistaken article reached a flawed conclusion. Intentionally or not, readers were misled, and the good name of the New Statesman has been used all over the internet by climate contrarians seeking to support their entrenched positions. This is regrettable. Good journalism should never exclude legitimate voices from a debate of public interest, but it also needs to distinguish between carefully-checked fact and distorted misrepresentations in complex and divisive areas like this. The magazine’s editorial policy is unchanged: we want to see aggressive action to reduce carbon emissions, and support global calls for planetary temperatures to be stabilised at under two degrees above pre-industrial levels.

Yes, scientific uncertainties remain in every area of the debate. But consider how high the stakes are here. If the 99% of experts who support the mainstream position are right, then we have to take urgent action to reduce emissions or face some pretty catastrophic consequences. If the 99% are wrong, and the 1% right, we will be making some unnecessary efforts to shift away from fossil fuels, which in any case have lots of other drawbacks and will soon run out. I’d hate to offend anyone here, but that’s what I’d call a no-brainer.

Divided Britain: how the EU referendum exposed Britain’s new culture war

The EU referendum exposed a gaping fault line in our society – and it’s not between left and right.

There are streets in Hampstead, the wealthy northern suburb of London, where the pro-EU posters outnumber cars. A red “Vote Remain” in one. A “Green Yes” in another. The red, white and blue flag of the official campaign sits happily next to a poster from the left-wing campaign Another Europe Is Possible proclaiming that the world already has too many borders.

If you were looking for an equivalent street in Hull, in the north of England, you would look for a long time. In the city centre when I visited one recent morning, the only outward evidence that there was a referendum going on was the special edition of Wetherspoon News plastered on the walls of the William Wilberforce pub in Trinity Wharf. Most of the customers agreed with the message from the chain’s founder, Tim Martin: Britain was better off outside the European Union.

“Far too much Hampstead and not enough Hull” – that was the accusation levelled at the Remain campaign by Andy Burnham in the final weeks of the campaign. He wasn’t talking about geography; Remain’s voice is persuasive to residents of Newland Avenue in Hull, where I drank a latte as I eavesdropped on a couple who were fretting that “racists” would vote to take Britain out of the EU.

Rather, Burnham was talking about an idea, the “Hampstead” that occupies a special place in right-wing demonology as a haven of wealthy liberals who have the temerity to vote in the interests of the poor. The playwright and novelist Michael Frayn, in his 1963 essay on the Festival of Britain, called them “the Herbivores”:

“. . . the radical middle classes, the do-gooders; the readers of the News Chronicle, the Guardian, and the Observer; the signers of petitions; the backbone of the BBC . . . who look out from the lush pastures which are their natural station in life with eyes full of sorrow for less fortunate creatures, guiltily conscious of their advantages, though not usually ceasing to eat the grass.”

For Hampstead then, read swaths of Islington, Hackney, Brighton, Bristol, Cambridge, Edinburgh and Oxford today – all areas that were most strongly in favour of Remain and where Jeremy Corbyn is popular. But Remain never found a tone that won over the other half of Labour England; the campaign struck as duff a note among the diminishing band of pensioners on Hampstead’s remaining council estates as it did on Hull’s Orchard Park Estate.

The rift between “Hampstead and Hull”, in the sense that Andy Burnham meant it, is one that has stealthily divided Britain for years, but it has been brought into sharp focus by the debate over Europe.

Academics use various kinds of shorthand for it: the beer drinkers v the wine drinkers, or the cosmopolitans v the “left behind”. “It’s not just that [Britain] is div­ided between people who buy organic and people who buy own-brand,” says Philip Cowley, a professor of politics at Queen Mary University of London, “but between people who wouldn’t understand how anyone could buy own-brand and people who wouldn’t buy organic if you put a gun to their head.” Equating political preferences with shopping habits might sound flippant, but on 21 June the retail research company Verdict estimated that “half of Waitrose shoppers backed a Remain vote, against just over a third of Morrisons customers”.

The referendum has shown that there is another chasm in British politics, beyond left and right, beyond social conservatism v liberalism, and beyond arguments about the size of the state. The new culture war is about class, and income, and education, but also about culture, race, nationalism and optimism about the future (or lack of it). This divide explains why Ukip’s message has been seductive to former Labour voters and to Tories, and why Boris Johnson, an Old Etonian, led a campaign that purported to despise “elites” and “experts” and spoke of “wanting our country back”.

***

At the start of the campaign, the question that most accurately predicted whether you would back Remain or Leave was consistently: “Are you a graduate?” (Those who answered yes were much more likely to vote in favour of staying in the EU.) Stronger In never found a way to change that and win over those who left education at 18 or earlier. Pollsters also suggested that the much-vaunted Euroscepticism of older voters reflects generations where only one in ten people went to university.

This fissure has been growing for the best part of a decade and a half, but Britain’s first-past-the-post system, which deters newcomers and maintains entrenched parties, has provided a degree of insulation to Labour that its European cousins have lacked. Yet even here in the UK the mid-Noughties brought the brief rise of the British National Party, powered by voter defections from Labour in its strongholds in east London and Yorkshire, as well as the election of the Greens’ first MP on the back of progressive disillusionment with the governments of Tony Blair and Gordon Brown.

In office, both Blair and Brown calculated, wrongly, that Labour’s core vote had “nowhere else to go”. In opposition under Ed Miliband, the party calculated, again wrongly, that discontent with immigration, and the rise of Ukip powered by that discontent, was a problem for the Conservative Party alone.

In a 2014 pamphlet for the Fabian Society, ­Revolt on the Left, the activist Marcus Roberts, the academic Rob Ford and the analyst Ian Warren warned that Labour had “few reasons to cheer about the Ukip insurgency and plenty to worry about”. When the votes were cast in the general election the following year, that prediction turned out to be dispiritingly accurate. Defections from Labour to Ukip led to Labour losing seats to the Conservatives in Gower, Southampton Itchen, Telford and Plymouth Moor View.

For the most part, however, first-past-the-post papered over the cracks in Labour’s broad coalition: cracks that, in the harsh light of the EU referendum, have become obvious. The divide isn’t simply one of class, or income. The social profile and culture of voters in Cumbria are no different from that of voters on the other side of the border – but Scots in the Borders backed a Remain vote while their English peers in the border areas opted for Brexit. Inhospitality towards Brexit proved a stronger indication of city status than a mere cathedral: Vote Leave generally found Britain’s great cities more difficult terrain than the surrounding towns and countryside.

The problem of the fracturing vote is particularly acute for the Labour Party, which for much of the 20th century was able to rely on the Herbivores. In concert with Frayn’s “less fortunate creatures”, they have been enough to guarantee Labour close to 250 seats in the House of Commons and roughly one-third of the popular vote, even in difficult years. But Britain’s EU referendum placed Hampstead and Hull on opposing sides for the first time in modern British political history.

It was Tony Blair who, in his final speech to the Trades Union Congress as Labour leader in September 2006, said that the new debate in politics was not left against right, but “open v closed” – openness to immigration, to diversity, to the idea of Europe. Driven by their commitment to openness, Blair’s outriders dreamed of reshaping Labour as a mirror of the US Democrats – though, ironically, it was Ed Miliband, who repudiated much of Blair’s approach and politics, who achieved this.

At the 2015 election Labour’s coalition was drawn from the young, ethnic minorities and the well educated: the groups that powered Barack Obama’s two election wins in 2008 and 2012. The party was repudiated in the Midlands, went backwards in Wales and was all but wiped out in the east of England. (Scotland was another matter altogether.) Its best results came in Britain’s big cities and university towns.

The Remain campaign gave Labour a glimpse of how Miliband’s manifesto might have fared without the reassuring imprimatur of a red rosette. Britain Stronger In Europe has been rejected in the Midlands and struggled in the east of England. But it also failed to inspire passion in Sunderland, Oldham and Hull – all areas that, for now, return Labour MPs.

In appearance, Hull’s city centre is built on blood and sandstone, dotted with memorials to a lost empire and postwar replacements for bombed buildings, all ringed by suburban housing built by the private sector in the 1930s and the state in the 1950s and 1960s. It could be Bristol without the excessive hills, or a smaller Glasgow with a different accent. Unlike in Glasgow or Bristol, however, the residents of Hull are largely hostile to the European Union. Unlike Glasgow and Bristol, Hull is a post-imperial city that has yet to experience a post-colonial second act.

The William Wilberforce is named after a native son who helped destroy the British slave trade, the engine of Hull’s prosperity in the 18th century. The destruction of another local industry – fishing – drives resentment among the pub’s ageing clientele, who were there for breakfast and a bit of company when I visited. They blame its demise squarely on the EU.

Although the Labour Party now has only one MP in Scotland, the back rooms of the labour movement host an outsized Scottish contingent. For that reason – and the continuing threat that the loss of Labour’s seats in Scotland poses to the party’s chances of winning a majority at Westminster – the Scottish independence referendum of 2014 loomed large for Labour throughout the EU campaign.

From the outset, Britain Stronger In struggled to replicate the success of the Scottish No campaign, in part because the price of victory was one that Labour regarded as too high to pay a second time. In Glasgow, in the week before the Scottish referendum, everyone knew where Labour stood on independence – consequently, many voters were already planning to take revenge. The proprietor of one café told me that Labour was “finished in this city, for ever”.

Predictions of this sort were thin on the ground in Hull. Alan Johnson, the head of Labour’s EU campaign, is one of the three Labour MPs whom Hull sent to Westminster in 2015. But even late in the campaign, in his own constituency, I found uncertainty about the party’s official position on the referendum. For that reason, if nothing else, it didn’t have the feeling of a city preparing to break with a half-century-plus of Labour rule, as Glasgow did in 2014. In Scotland, most people I spoke to believed that they were on the brink of independence, which made the eventual result a big blow.

Only among Hull’s pro-European minority could I find any conviction that Britain might actually leave the EU. In September 2014 Kenneth Clarke remarked that Ukip’s supporters were “largely . . . the disappointed elderly, the grumpy old men, people who’ve had a bit of a hard time in life”. To listen to Hull’s Leave voters is to hear tales of the same frustrated potential: they feel that politicians of all stripes have lives entirely removed from theirs. In their defence, they are right – just 4 per cent of MPs in 2010 were from working-class backgrounds.

As for Ken Clarke, he has carved out a second career as every left-winger’s favourite Tory, but that tone of indifference towards the “disappointed lives” of globalisation’s casualties recalls his younger days as a rising star of Margaret Thatcher’s government.

Hull’s residents have been dismissed, first as the regrettable but inevitable consequence of Thatcherite economics, and now as small-minded opponents of social progress and racial diversity. Unsurprisingly, people who feel that their wishes have been ignored and in some cases actively squashed by successive governments of left and right did not expect to wake up on the morning of 24 June to discover that this time, their votes really had changed something.

Equally unsurprisingly, the Remain campaign’s warnings of economic collapse lacked force for people for whom the world’s end had been and gone.

In Glasgow in 2014 Scottish independence was a question of identity in itself, whereas in Hull, hostility towards Europe is the by-product of other identities that feel beleaguered or under threat: fishing, Englishness and whiteness, for the most part.

In Hampstead, a vote for Remain feels more like a statement about the world as you see it. One woman, who walks off before I can probe further, tells me: “Of course I’m voting to stay In. I buy Fairtrade.”

Immigration, not the European Union, is the issue that moves voters in Hull. “Britain is full” was the most frequent explanation they gave for an Out vote. Knowing that immigration, rather than the abstract question of sovereignty, would be crucial to winning the contest, Vote Leave tried from the beginning to make it a referendum on border control. Leave’s main theme: the threat of Turkey joining the European Union and, with it, the prospect of all 75 million Turks gaining the right to live and work in Britain.

Although Turkey’s chances of joining the EU are somewhere only just north of its hopes of launching a manned mission to Mars, the tactic worked: according to an ­Ipsos MORI poll released on the morning of 16 June, 45 per cent of Britons believed that Turkey will be fast-tracked into the Union.

That same morning, Nigel Farage posed in front of a poster showing refugees – mostly from Syria and most of them non-white – on the border between Croatia and Slovenia, with a slogan warning that uncontrolled immigration was leaving Britain at “breaking point”. But the row over the poster came to an unpleasant halt just a few hours later as news began to break that Jo Cox, the Labour MP for Batley and Spen, had been shot and stabbed on her way out of a constituency surgery. She died of her injuries a little over an hour later. On 19 June Thomas Mair, who was arrested in connection with the killing, gave his name at Westminster Magistrates’ Court as “Death to traitors, freedom for Britain”.

The circumstances of the killing felt familiar. A little after midnight on 5 June 1968, Robert Kennedy was returning to the Ambassador Hotel in Los Angeles in high spirits. He had just won a crucial victory in the California primary and was well placed to secure the Democratic nomination to run in that year’s presidential election. Going through the kitchen in order to avoid cheering crowds and get straight to his press conference, he was ambushed by a man called Sirhan Sirhan, who fired six shots from a revolver. Kennedy was rushed to hospital, where he died early the following morning.

Five months later Richard Nixon was elected president. The American right held on to the White House for 20 years out of the next 25. Jo Cox’s killing, amid the nativist howling from Farage et al, felt like the beginning of a similar chapter of right-wing advance in the UK.

Labour’s problem, and that of its social-democratic cousins throughout Europe, is the same as the American left’s was in the 1960s. Its founding coalition – of trade unions, the socially concerned middle classes and minorities, ethnic and cultural – is united (barely) on economic issues but irrevocably split on questions of identity. Outside crisis-stricken Greece and Spain, the left looks trapped in permanent opposition, with no politician able to reconsolidate its old base and take power again.

When I arrive in Hull, preparations are under way for a vigil in Jo Cox’s honour, but it is the nation of Turkey that is weighing on the minds of undecided voters. On Park Street, residents are divided. Those who have exercised their right to buy and are concerned about their mortgages are flirting with an Out vote but are terrified about negative equity. Those who remain in social housing or the private rented sector are untouched by stories of soaring mortgages. To many residents, the Treasury’s dire warnings seem to be the concerns of people from a different planet, not merely another part of the country. As Rachel, a woman in her mid-fifties who lives alone, puts it: “They say I’d lose four grand a month. I don’t know who they think is earning four grand a month but it certainly isn’t me.”

As Vote Leave knew, the promise that an Out vote will allow people to “take control” always had a particular appeal for those with precious little control – of their rent, of next week’s shift, of whether or not they will be able to afford to turn the heating on next week. Never mind that the control envisaged by Vote Leave would be exercised by the conservative right: the campaign found a message that was able to resonate across class and region, at least to an extent that could yet create a force to be reckoned with under first-past-the-post in Britain.

Four grand a month isn’t a bad salary, even in leafy Hampstead, but in that prosperous corner of north London fears of an Out vote, and what will come after, gained a tight purchase. The worry was coupled with resentment, too, over what would come, should the Outers triumph.

The great risk for the left is that herbivorous resentment is already curdling into contempt towards the people of Hull and the other bastions of Brexitism. That contempt threatens the commodity on which Labour has always relied to get Hull and Hampstead to vote and work together – solidarity. The referendum leaves the Conservatives divided at Westminster. That will give little comfort to Labour if the long-term outcome of the vote is to leave its own ranks divided outside it.
