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 Great Huckster: Boris Johnson’s reckless distortions of history

As a scholar of Churchill, Boris Johnson could have articulated a constructive vision for Britain and Europe. Instead, he wilfully manipulates and distorts the historical record.

This month, 76 years ago, the defeated British Expeditionary Force was making for the Channel ports. Thanks to the ferocious resistance put up by the garrison at Calais, and Hitler’s hesitation, the bulk of the men were safely taken off the beaches at Dunkirk to fight another day. Whatever their private feelings during those terrible hours may have been, most of them knew even then that they would return to Europe to finish the job.

Their forefathers had been intervening in Europe for as long as anyone could remember. From Shakespeare’s Henry V through to Elizabeth’s support for the Dutch revolt, the Second Hundred Years War against Louis XIV, the French Revolution and Napoleon, and the First World War, London had always been profoundly invested in the continent. Defending the “liberties of Europe” and thus British freedoms was what Englishmen and Britons did. It was part of what they were.

In early June 1944 – on D-Day – the British, Americans and Canadians hurled themselves into northern France as their ancestors had done since the late Middle Ages. At least one British officer tried to inspire his men that morning as the landing craft approached the strongly defended beaches by reading out Henry V’s speech before Harfleur, in which Shakespeare has him exhort the men, “once more unto the breach”. The film version of the play was released that same year, dedicated to the “commando and airborne troops of Great Britain”. In the popular mind, these Englishmen and their North American descendants were part of the continuity of a European story that went back to the medieval English empire in France.

Some of those liberating Europe thought that they could not simply return to “business as usual” after the war. One of them was the later Conservative prime minister Ted Heath, the man who took Britain into the European Economic Community in 1973. He first defended Liverpool as an anti-aircraft gunner and then took the fight to Hitler as an artillery man during the campaign in north-west Europe. Over the course of the next 11 months, Heath and his comrades fought their way across the traditional battlefields of northern France and the Low Countries, including the Walcheren swamps in which their ancestors had been mired in Napoleonic times; and through western Germany into the centre of the Reich. They were to stay there, at the heart of Europe, for some 60 years. They created a stable European order, based on Nato and what was to become the European Union, which remains with us to this day.

Now the Brexit stalwart Boris Johnson, my fellow historian, claims that it was all in vain. “The European Union,” he says, “is an attempt to do what Hitler wanted by different methods.” Worse still, the EU is a German plot, whose currency, the euro, was “intended by the Germans” to “destroy” Italian manufacturing and generally grind the faces of its unfortunate members. Johnson has also invoked the spirit of Churchill in support of his arguments. He has since doubled down on his remarks and has received support from other members of the Brexit camp, such as Iain Duncan Smith, though not apparently from more informed figures such as Michael Gove. Unfortunately, Johnson’s claims are as historically wrong as it is possible to be, comparable in their crassness only to his predecessor as London mayor Ken Livingstone’s suggestion that Hitler supported Zionism.

Far from supporting European political unity, Hitler was violently and explicitly opposed to the idea. This was partly because it was proposed by his opponents on the “left” of the Nazi Party, such as the Strasser brothers. They belonged to the “anti-imperialist” wing of the Nazi Party, which wanted a pan-European front against the Jews and the British empire. Hitler’s hostility to the European project was also in part due to a racial antipathy to the half-Japanese Richard, Count Coudenhove-Kalergi, the author of the widely discussed book Pan-Europa (1923). One way or the other, Hitler condemned the Pan-Europa movement as “a fantastical, historically impossible childishness”, which would be no more than a “Jewish protectorate”.

Nor did he hold back with his alternative view of what the continent should look like. “The solution,” he wrote, “cannot be Pan-Europa, but rather a Europe of free and independent national states, whose spheres of interest are separate and clearly delineated.” Comparisons involving Hitler are usually odious but if one is going to draw parallels, his view of European integration then was much closer to that of the Brexiters today than that of the advocates of the European Union.

Moreover, the European project did not originate in the Nazis’ attempt to mobilise the continent on their behalf but rather in the resistance movement against Hitler. Take Sicco Mansholt, who hid Dutch resisters on his farm during the war, at great personal risk. He subsequently became the Dutch minister for agriculture and one of the fathers of the Common Agricultural Policy (CAP). Take Altiero Spinelli, the Italian anti-fascist who spent ten years in Mussolini’s prisons. It was there, in June 1941, at the height of Hitler’s power, that he secretly wrote his draft manifesto For a Free and United Europe.

Take Paul-Henri Spaak, later prime minister of Belgium, first president of the Common Assembly of the European Coal and Steel Community – the forerunner of the EU – and secretary-general of Nato. He was forced to make a daring escape from wartime Europe in the false bottom of a lorry in order to carry on the struggle against Hitler in exile. Indeed, across Europe there were thousands of men and women who fought, died, were imprisoned or tortured because they believed in a free and united Europe. To suggest that they were trying to achieve the same thing as Hitler by different methods is an outrageous slur on their memory. If Johnson ever makes it to the top of the Conservative Party, and thence to No 10, he will have a lot of explaining and apologising to do in Europe.

As if all this were not bad enough, Boris Johnson’s invocation of Churchill flies in the face of everything we know of the great man’s attitude to the European project. To be sure, he began as a Eurosceptic. When army reforms were proposed in 1901 to support the creation of a substantial land force on the continent, the young Winston Churchill was one of the few MPs to oppose them on the grounds that the navy, rather than the army, was of crucial importance to British security. Writing in the Morning Post, Churchill argued that “history” and “geography” showed that the British empire was “essentially commercial and marine”, and had been defended by armies of foreigners.

As the German threat loomed large, however, he changed his mind. Churchill, then first lord of the admiralty, told the Australians and New Zealanders in April 1913 that Europe was “where the weather came from”. It was the terrible storm of the First World War that caused Churchill not only to believe in the centrality of Europe but in the need for European – or at least continental European – unity.

In May 1930, the president of the Pan-Europa Union, the former French prime minister Aristide Briand, made a formal proposal for a “European federal union” based on a “European conference” with an executive to co-ordinate economic and military co-operation. The British government of the time rejected the surrender of sovereignty involved but many were sympathetic to the idea of continental European union under liberal auspices. The arch-imperialist Leo Amery, secretary of state for the colonies and later a powerful critic of appeasement, was a strong admirer of Coudenhove and his projects, which he regarded as the extension of Anglo-Saxon principles to the continent.

Likewise, Churchill, then chancellor of the Exchequer, told parliament in June 1925 that he hoped that one could “weave Gaul and Teuton so closely together economically, socially and morally as to prevent the occasion of new quarrels and make old antagonisms die in the realisation of mutual prosperity and interdependence”. Then, he continued, “Europe could rise again”. Churchill did not believe, however, that Britain should be part of any continental political union. “We are with Europe, but not of it,” he wrote in 1930. “We are linked but not compromised. We are interested and associated but not absorbed.”

In mid-June 1940, however, as western Europe buckled under the Nazi onslaught, Churchill went a step further. He made an unsuccessful offer of union with France – involving joint citizenship and a common government – designed to lock the French into the war effort against Germany or, failing that, to secure their fleet. The Nazi threat was so existential, in other words, that it justified the surrender, or at least the pooling, of British sovereignty.

When the threat of invasion passed, Churchill returned to the theme of continental European integration. In October 1942, he “look[ed] forward to a United States of Europe in which barriers between the nations will be greatly minimised. He “hope[d] to see the economy of Europe studied as a whole”, and the establishment of a council of “ten units, including the former Great Powers [and thus presumably Britain], with several confederations – Scandinavian, Danubian, Balkan, etc, which would possess an international police and be charged with keeping Prussia disarmed”.

Churchill returned to the subject immediately after the war, as the Soviet threat menaced Europe. In a speech at Zurich University in September 1946, he urged the continent to “unite”, with Britain supporting the project from the outside. Once again, including the Germans was central to his conception. Churchill urged no less than the full political union of the continent in a “kind of United States of Europe” under the “principles embodied in the Atlantic Charter”. He again praised the work of Hitler’s bugbear, Count Coudenhove-Kalergi’s “Pan-European Union”.

Churchill demanded an “act of faith”, beginning with “a partnership between France and Germany”, assembling around them the states of Europe “who will and . . . can” join such a union. Its purpose was clear, namely “to make the material strength of a single state less important. Small nations will count as much as large ones and gain their honour by their contribution to the common cause.”

Moreover, Churchill argued, “The ancient states and principalities of Germany, freely joined together for mutual convenience in a federal system, might each take their individual place among the United States of Europe.” In short, the new polity was designed to solve not merely the European question but the German problem, the two being one and the same. Once again, Churchill conceived of this United States of Europe alongside but not including the United Kingdom and the British “Commonwealth of Nations”, that is, the empire. Instead, he believed that Britain should be one of the “sponsors of the new Europe”.

Churchill’s attitude to continental European union was, unlike Hitler’s, highly positive. For Johnson to suggest, therefore, that he is donning the mantle of Churchill to prevent the current European Union from achieving Hitler’s aims through other means is a complete travesty of the historical truth.

Far from being intended to promote German power, the European Union was designed to contain it, or at least to channel it in the right direction. Contrary to what Johnson suggests, the euro was not planned by Germany to subjugate Italian industry or any other European economy. It was insisted on by the French to decommission the deutschmark, which they described as Germany’s “nuclear weapon”. Likewise, the Germans are not incarcerating the Greeks in their European prison: Greeks are desperate not to be released back into the “freedom” of the drachma and the corrupt national politics that they joined “Europe” to escape. If there is one thing worse than being dominated by Germany in the European Union, evidently, it is not being in the EU at all.

Boris Johnson may not have known the details of Hitler’s attitude to European integration, or the European sympathies of many resisters, but he is very well informed about Churchill and Europe. His ignorance is thus not just a matter of making mistakes; we all make those as historians. Nor is it simply a matter of these mistakes being, like bank errors, in favour of one’s own argument. To say that Johnson knows better is not a figure of speech: he has shown in print that he does. His recent book, The Churchill Factor, contains a very balanced account of Churchill’s position on Europe, including most of the statements listed above.

In making his arguments, Johnson is not appealing to the baser instincts of the electorate; it is far worse than that. The deeply ingrained British instinct to fight European tyranny is not base but fine. What Johnson and those who defend his rhetoric have done is to take something virtuous and pervert it. The European Union is not, as we have seen, the continuation of Hitlerism by other means and to suggest so is blatant manipulation.

The shame of it is that there is a perfectly plausible Eurosceptic argument on its own merits. It was well stated by Michael Gove at the start of the campaign. It insists on the historical distinctiveness of the United Kingdom, whose history does indeed set it apart from the rest of the continent. It makes the case for a reform of the EU. It rejects the scaremongering of “Project Fear”, on the cogent grounds that the United Kingdom has the political, economic and military weight to prevail even without the stabilisers of the EU. It scorns President Obama’s impertinent warning that Britain would have to “get to the back of the queue” for a trade deal after Brexit, with a reminder that Britain and her empire defied Nazi Germany for two years before the Americans joined the fray, when Hitler declared war on them (not vice versa). One does not have to accept every detail of this discourse to feel its force. Uniquely among the democratic European powers, the United Kingdom can “stand alone” if it must or wants to.

The Achilles heel of the Brexit campaign, however, is that it has no viable vision for continental Europe. Even Gove falls down here, as his idea of a British departure unleashing a “democratic liberation” of the continent is pure fantasy. It seems odd to have to explain this to Brexiters but Britain really is special. Casting off the bonds of Brussels will not emancipate mainland Europe but let loose the nationalist and xenophobic demons tamed by the integration project. This is clear when we look at the rise of radical anti-European parties in France, Hungary, Austria, Germany and many other parts of Europe as the European project fragments. These developments should not surprise anyone who knows the history of mainland Europe before the mid-20th century and to a considerable sense beyond.

Most of continental Europe had failed before 1945 and even now the European Union is only failing better. Unlike virtually every other European state, which has at some point or other been occupied and dismembered, often repeatedly, England and the United Kingdom have largely – with very brief exceptions – been subjects of European politics, never merely objects. In this sense, too, she is exceptional. Yet this should not be an occasion for British triumphalism. Whatever the outcome of the referendum on 23 June, the European Union is not an enemy of the United Kingdom. It should best be understood as a modern version of the old Holy Roman Empire; hapless and officious, perhaps, but not malign. It needs help. The failure of the European project and the collapse of the current continental order would be not only a catastrophic blow to the populations on the far side of the Channel but also to the United Kingdom, which would be
directly exposed to the resulting disorder, as it always has been.

In short, the Brexit camp in general and Boris Johnson in particular are missing a great opportunity in Europe. A student and partisan of Winston Churchill, the former mayor of London was qualified to articulate a constructive vision for Britain and the continent. He has failed to understand that the only safe way that Britain can exit from the European Union is not through Brexit – whose consequences for mainland Europe would be dire – but through Euroexit; that is, a Churchillian political union of the continent in close co-operation with the UK.

Instead, in addition to their distortion of the historical record, Johnson and the Brexit camp are committing the cardinal sin of making a decision before they need to. The European Union is not, sadly, a United States of Europe, even though it needs to become one to survive, and is becoming less like one every day. If and when it musters the strength for full political union, there will be plenty of time to leave. Meanwhile, the EU needs all the support that Britain can give it from within.

In 1940, the British forces had been defeated and retreat was the only option. The situation could not be more different today. This is no time to head for the beaches in what will be a legislative Dunkirk of epic proportions, with incalculable consequences not so much for Britain as for the rest of the continent. Unlike in 1940, the United Kingdom is not being forced out of Europe. It has hardly begun to fight there, unless shooting oneself in the foot through Brexit counts as combat. The battle in Britain today is a distraction from the great struggle on the mainland. There is much work to be done in Europe. It is time the British stop tearing themselves apart and return unto the breach once more.
