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.

Mark Lynas has is an environmental activist and a climate change specialist. His books on the subject include High Tide: News from a warming world and Six Degree: Our future on a hotter planet.

The lost magic of England

The great conservative journalist Peregrine Worsthorne reflects on a long life at the heart of the establishment.

In a recent editorial meeting, our subscriptions manager happened to mention that Peregrine Worsthorne was still a New Statesman subscriber. A former editor of the Sunday Telegraph and, during a long Fleet Street career, a self-styled “romantic reactionary” scourge of liberals and liberalism, Worsthorne used to be something of a pantomime villain for the left, a role he delighted in. He had close friends among the “Peterhouse right”, the group of High Tory intellectuals who gathered around Maurice Cowling at the small, conspiratorial Cambridge college. He was a frequent contributor to Encounter (which turned out to be funded by the CIA) and an ardent cold warrior. His social conservatism and lofty affectations offended lefty Islingtonian sensibilities. On several occasions he was the Guardian’s reviewer of choice for its annual collection of journalism, The Bedside Guardian, and he invariably delivered the required scornful appraisal while praising its witty television critic, Nancy Banks-Smith. There is no suggestion, he wrote in 1981, that the “Guardian ever sees itself as part of the problem; itself as having some responsibility for the evils its writers described so well”.

His prose style was Oxbridge high table, more Walter Pater than George Orwell. It was essential not to take Worsthorne too seriously, because he delighted in mischief-making and wilful provocation – one of his targets for remorseless ridicule was Andrew Neil, when Neil edited the abrasively Thatcherite Sunday Times. He ended up suing Worsthorne, who was famous for his silk shirts and Garrick Club lunches, for libel; he was awarded damages of £1, the then cover price of the Sunday Times.

“I wrote that in the old days editors of distinguished Sunday papers could be found dining at All Souls, and something must have changed when they’re caught with their trousers down in a nightclub,” Worsthorne told me when we met recently. “I had no idea he was going to sue. I was teasing. I occasionally run into him and we smile at each other, so it’s all forgotten and forgiven.”

After his retirement in 1989, Worsthorne, although he remained a resolute defender of aristocracy, seemed to mellow, and even mischievously suggested that the Guardian had replaced the Times as the newspaper of record. In the 1990s he began writing occasionally for the New Statesman – the then literary editor, Peter Wilby, commissioned book reviews from him, as I did after I succeeded Wilby. Like most journalists of his generation, Worsthorne was a joy to work with; he wrote to length, delivered his copy on time and was never precious about being edited. (Bill Deedes and Tony Howard were the same.) He might have had the mannerisms of an old-style toff but he was also a tradesman, who understood that journalism was a craft.

Shortly before Christmas, I rang Wors­thorne at the home in Buckinghamshire he shares with his second wife, Lucinda Lambton, the charming architectural writer. I asked how he was. “I’m like a squeezed lemon: all used up,” he said. Lucy described him as being “frail but not ill”. I told him that I would visit, so one recent morning I did. Home is a Grade II-listed old rectory in the village of Hedgerley. It is grand but dishevelled and eccentrically furnished. A sign on the main gates warns you to “Beware of the Dog”. But the dog turns out to be blind and moves around the house uneasily, poignantly bumping into objects and walls. At lunch, a small replica mosque in the dining room issues repeated mechanised calls to prayer. “Why does it keep doing that?” Perry asks. “Isn’t it fun,” Lucy says. She then turns to me: “Have some more duck pâté.”

As a student, I used to read Worsthorne’s columns and essays with pleasure. I did not share his positions and prejudices but I admired the style in which he articulated them. “The job of journalism is not to be scholarly,” he wrote in 1989. “The most that can be achieved by an individual newspaper or journalist is the articulation of an intelligent, well-thought-out, coherent set of prejudices – ie, a moral position.”

His Sunday Telegraph, which he edited from 1986 to 1989, was like no other newspaper. The recondite and reactionary comment pages (the focus of his energies) were unapologetically High Tory, contrary to the prevailing Thatcherite orthodoxies of the time, but were mostly well written and historically literate. Bruce Anderson was one of the columnists. “You never knew what you were going to get when you opened the paper,” he told me. “Perry was a dandy, a popinjay, and of course he didn’t lack self-esteem. He had a nostalgia for Young England. In all the time I wrote for him, however, I never took his approval for granted. I always felt a tightening of the stomach muscles when I showed him something.”

Worsthorne is 92 now and, though his memory is failing, he remains a lucid and engaging conversationalist. Moving slowly, in short, shuffling steps, he has a long beard and retains a certain dandyish glamour. His silver hair is swept back from a high, smooth forehead. He remains a stubborn defender of the aristocracy – “Superiority is a dread word, but we are in very short supply of superiority because no one likes the word” – but the old hauteur has gone, replaced by humility and a kind of wonder and bafflement that he has endured so long and seen so much: a journalistic Lear, but one who is not raging against the dying of the light.

On arrival, I am shown through to the drawing room, where Perry sits quietly near an open fire, a copy of that morning’s Times before him. He moves to a corner armchair and passes me a copy of his book Democracy Needs Aristocracy (2005). “It’s all in there,” he says. “I’ve always thought the English aristocracy so marvellous compared to other ruling classes. It seemed to me that we had got a ruling class of such extraordinary historical excellence, which is rooted in England
almost since the Norman Conquest.

“Just read the 18th-century speeches – the great period – they’re all Whig or Tory, but all come from that [the aristocracy]. If they didn’t come directly from the aristocracy, they turned themselves very quickly into people who talk in its language. Poetic. If you read Burke, who’s the best in my view, it’s difficult not to be tempted to think what he says has a lot of truth in it . . .”

His voice fades. He has lost his way and asks what we were talking about. “Oh, yes,” he says. “It survived when others – the French and Russians and so on – were having revolutions. It was absolutely crazy to set about destroying that. There was something magical . . . the parliamentary speeches made by Burke and so on – this is a miracle! No other country has it apart from America in the early days. And I thought to get rid of it, to undermine it, was a mistake.”

I ask how exactly the aristocracy was undermined. Even today, because of the concentration of the ownership of so much land among so few and because of the enduring influence of the old families, the great schools and Oxbridge, Britain remains a peculiar hybrid: part populist hyper-democracy and part quasi-feudal state. The Tory benches are no longer filled by aristocrats but the old class structures remain.

“Equality was the order of the day after the war,” Worsthorne replies. “And in a way it did a lot of good, equalising people’s chances in the world. But it didn’t really get anywhere; the ruling class went happily on. But slowly, and I think unnecessarily dangerously, it was destroyed – and now there are no superior people around [in politics]. The Cecil family – Lord Salisbury, he was chucked out of politics. The Cecil family is being told they are not wanted. The institutions are falling apart . . .

“But there were people who had natural authority, like Denis Healey. I’m not saying it’s only aristocrats – a lot of Labour people had it. But now we haven’t got any Denis Healeys.”

Born in 1923, the younger son of Alexander Koch de Gooreynd, a Belgian banker, Worsthorne (the family anglicised its name) was educated at Stowe and was an undergraduate at both Cambridge (Peterhouse, where he studied under the historian Herbert Butterfield, the author of The Whig Interpretation of History) and Oxford (Magdalen College). “I have always felt slightly underprivileged and de-classed by having gone to Stowe, unlike my father who went to Eton,” Worsthorne wrote in 1985.

Yet his memories of Stowe remain pellucid. There he fell under the influence of the belle-lettrist John Davenport, who later became a close friend of Dylan Thomas. “He was a marvellous man, a famous intellectual of the 1930s, an ex-boxer, too. But in the war he came to Stowe and he was preparing me for a scholarship to Cambridge. He told me to read three books, and find something to alleviate the boredom of an examiner, some little thing you’ll pick up. And I duly did and got the scholarship.”

Can you remember which three books he recommended?

“Tawney. Something by Connolly, um . . . that’s the terrible thing about getting old, extremely old – you forget. And by the time you die you can’t remember your brother’s name. It’s a terrible shock. I used to think old age could be a joy because you’d have more time to read. But if you push your luck and get too far, and last too long, you start finding reading really quite difficult. The connections go, I suppose.”

Was the Connolly book Enemies of Promise (1938)?

“Yes, that’s right. It was. And the other one was . . . Hang on, the writer of the book . . . What’s the country invaded by Russia, next to Russia?

Finland, I say. Edmund Wilson’s To the Finland Station (1940)?

“Yes. Wilson. How did you get that?”

We both laugh.

***

Worsthorne is saddened but not surprised that so many Scots voted for independence and his preference is for Britain to remain a member of the European Union. “What’s happening is part of the hopelessness of English politics. It’s horrible. I can’t think why the Scots would want to be on their own but it might happen. The youth will vote [for independence]. This is part of my central theme: the Scots no longer think it’s worthwhile belonging to England. The magic of England has gone – and it’s the perversity of the Tory party to want to get us out of the European Union when of course we’re much more than ever unlikely to be able to look after ourselves as an independent state because of the quality of our political system.

“The people who want to get us out are obviously of an undesirable kind. That the future should depend on [Nigel] Farage is part of the sickness. I mean the real horror is for him to have any influence at all. And when you think of the great days of the Labour Party, the giants who strode the stage – famous, lasting historical figures, some of them: Healey, Attlee, who was probably the greatest, [Ernest] Bevin. I’m well aware that Labour in the good days produced people who were superior.”

He digresses to reflect on his wartime experience as a soldier – he served in Phantom, the special reconnaissance unit, alongside Michael Oakeshott, the philosopher of English conservatism who became a close friend, and the actor David Niven, our “prize colleague”.

“I remember Harold Macmillan saying to me, after the Second World War, the British people needed their belt enlarged; they’d done their job and they deserved a reward. And that’s what he set about doing. And he wasn’t a right-wing, unsympathetic man at all. But he didn’t – and this is what is good about conservatism – he didn’t turn it into an ‘ism’. It was a sympathetic feel, an instinctive feel, and of course people in the trenches felt it, too: solidarity with the rest of England and not just their own brotherhood. Of course he didn’t get on with Margaret Thatcher at all.”

Worsthorne admired Thatcher and believed that the “Conservatives required a dictator woman” to shake things up, though he was not a Thatcherite and denounced what he called her “bourgeois triumphalism”. He expresses regret at how the miners were treated during the bitter strike of 1984-85. “I quarrelled with her about the miners’ strike, and the people she got around her to conduct it were a pretty ropey lot.

“I liked her as a person. I was with her that last night when she wasn’t prime minister any more, but she was still in Downing Street and had everything cut off. The pressman [Bernard Ingham] got several of us to try to take her mind off her miseries that night. There’s a photograph of me standing at the top of the stairs.”

In the summer of 1989, Peregrine Wors­thorne was sacked as the editor of the Sunday Telegraph by Andrew Knight, a former journalist-turned-management enforcer, over breakfast at Claridge’s. He wrote about the experience in an elegant diary for the Spectator: “I remember well the exact moment when this thunderbolt, coming out of a blue sky, hit me. It was when the waiter had just served two perfectly poached eggs on buttered toast . . . In my mind I knew that the information just imparted was a paralysingly painful blow: pretty well a professional death sentence.”

He no longer reads the Telegraph.

“Politically they don’t have much to say of interest. But I can’t put the finger on exactly what it is I don’t like about it. Boredom, I think!”

You must read Charles Moore?

“He is my favourite. Interesting fellow. He converted to Catholicism and started riding to hounds in the same week.”

He has no regrets about pursuing a long career in journalism rather than, say, as a full-time writer or academic, like his friends Cowling and Oakeshott. “I was incredibly lucky to do journalism. What people don’t realise – and perhaps you don’t agree – but it’s really a very easy life, compared to many others. And you have good company in other journalists and so on. I was an apprentice on the Times, after working [as a sub-editor] on the Glasgow Herald.”

How does he spend the days?

“Living, I suppose. It takes an hour to get dressed because all the muscles go. Then I read the Times and get bored with it halfway through. Then there’s a meal to eat. The ­answer is, the days go. I used to go for walks but I can’t do that now. But Lucy’s getting me all kinds of instruments to facilitate people with no muscles, to help you walk. I’m very sceptical about it working, but then again, better than the alternative.”

He does not read as much as he would wish. He takes the Statesman, the Spectator and the Times but no longer the Guardian. He is reading Niall Ferguson’s biography of Kissinger, The Maisky Diaries by Ivan Maisky, Stalin’s ambassador to London from 1932 to 1943, and Living on Paper, a selection of letters by Iris Murdoch, whom he knew. “I get these massive books, thinking of a rainy day, but once I pick them up they are too heavy, physically, so they’re stacked up, begging to be read.”

He watches television – the news (we speak about Isis and the Syrian tragedy), the Marr show on Sunday mornings, and he has been enjoying War and Peace on BBC1. “Andrew Marr gave my book a very good review. He’s come back. He’s survived [a stroke] through a degree of hard willpower to get back to that job, almost as soon as he came out of surgery. But I don’t know him; he was a Guardian man.” (In fact, Marr is more closely associated with the Independent.)

Of the celebrated Peterhouse historians, both Herbert Butterfield (who was a Methodist) and Maurice Cowling were devout Christians. For High Tories, who believe in and accept natural inequalities and the organic theory of society, Christianity was a binding force that held together all social classes, as some believe was the order in late-Victorian England.

“I was a very hardened Catholic,” Worsthorne says, when I mention Cowling’s book Religion and Public Doctrine in Modern England. “My mother was divorced [her second marriage was to Montagu Norman, then the governor of the Bank of England] and she didn’t want my brother and me to be Catholic, so she sent us to Stowe. And I used to annoy her because I read [Hilaire] Belloc. I tried to annoy the history master teaching us Queen Elizabeth I. I said to him: ‘Are you covering up on her behalf: don’t you know she had syphilis?’

“Once I felt very angry about not being made Catholic. But then I went to Cambridge and there was a very Catholic chaplain and he was very snobbish. And in confession I had to tell him I masturbated twice that morning or something, and so it embarrassed me when half an hour later I had to sit next to him at breakfast. I literally gave up going to Mass to get out of this embarrassing situation. But recently I’ve started again. I haven’t actually gone to church but I’ve made my confessions, to a friendly bishop who came to the house.”

So you are a believer?

“Yes. I don’t know which bit I believe. But as Voltaire said: ‘Don’t take a risk.’”

He smiles and lowers his head. We are ready for lunch.
