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.

Why the elites always rule

Since an Italian sociologist coined the word “elite” in 1902, it has become a term of abuse. But history is the story of one elite replacing another – as the votes for Trump and Brexit have shown.

Donald Trump’s successful presidential campaign was based on the rejection of the “establishment”. Theresa May condemned the rootless “international elites” in her leader’s speech at last October’s Conservative party conference. On the European continent, increasingly popular right-wing parties such as Marine Le Pen’s Front National and the German Alternative für Deutschland, as well as Poland’s ruling Law and Justice party, delight in denouncing the “Eurocratic” elites. But where does the term “elite” come from, and what does it mean?

It was Vilfredo Pareto who, in 1902, gave the term the meaning that it has today. We mostly think of Pareto as the economist who came up with ideas such as “Pareto efficiency” and the “Pareto principle”. The latter – sometimes known as the “power law”, or the “80/20 rule” – stipulates that 80 per cent of the land always ends up belonging to 20 per cent of the population. Pareto deduced this by studying land distribution in Italy at the turn of the 20th century. He also found that 20 per cent of the pea pods in his garden produced 80 per cent of the peas. Pareto, however, was not only an economist. In later life, he turned his hand to sociology, and it was in this field that he developed his theory of the “circulation of elites”.

The term élite, used in its current socio­logical sense, first appeared in his 1902 book Les systèmes socialistes (“socialist systems”). Its aim was to analyse Marxism as a new form of “secular” religion. And it was the French word élite that he used: naturally, one might say, for a book written in French. Pareto, who was bilingual, wrote in French and Italian. He was born in Paris in 1848 to a French mother and an Italian father; his father was a Genoese marquis who had accompanied the political activist Giuseppe Mazzini into exile. In honour of the revolution that was taking place in Germany at the time, Pareto was at first named Fritz Wilfried. This was latinised into Vilfredo Federico on the family’s return to Italy in 1858.

When Pareto wrote his masterpiece – the 3,000-page Trattato di sociologia ­generale (“treatise on general sociology”) – in 1916, he retained the French word élite even though the work was in Italian. Previously, he had used “aristocracy”, but that didn’t seem to fit the democratic regime that had come into existence after Italian unification. Nor did he want to use his rival Gaetano Mosca’s term “ruling class”; the two had bitter arguments about who first came up with the idea of a ruling minority.

Pareto wanted to capture the idea that a minority will always rule without recourse to outdated notions of heredity or Marxist concepts of class. So he settled on élite, an old French word that has its origins in the Latin eligere, meaning “to select” (the best).

In the Trattato, he offered his definition of an elite. His idea was to rank everyone on a scale of one to ten and that those with the highest marks in their field would be considered the elite. Pareto was willing to judge lawyers, politicians, swindlers, courtesans or chess players. This ranking was to be morally neutral: beyond “good and evil”, to use the language of the time. So one could identify the best thief, whether that was considered a worthy profession or not.

Napoleon was his prime example: whether he was a good or a bad man was irrelevant, as were the policies he might have pursued. Napoleon had undeniable political qualities that, according to Pareto, marked him out as one of the elite. Napoleon is important
because Pareto made a distinction within the elite – everyone with the highest indices within their branch of activity was a member of an elite – separating out the governing from the non-governing elite. The former was what interested him most.

This is not to suggest that the non-governing elite and the non-elite were of no interest to him, but they had a specific and limited role to play, which was the replenishment of the governing elite. For Pareto, this group was the key to understanding society as a whole – for whatever values this elite incarnated would be reflected in society. But he believed that there was an inevitable “physiological” law that stipulated the continuous decline of the elite, thereby making way for a new elite. As he put it in one of his most memorable phrases, “History is the graveyard of elites.”

***

Pareto’s thesis was that elites always rule. There is always the domination of the minority over the majority. And history is just the story of one elite replacing another. This is what he called the “circulation of elites”. When the current elite starts to decline, it is challenged and makes way for another. Pareto thought that this came about in two ways: either through assimilation, the new elite merging with elements of the old, or through revolution, the new elite wiping out the old. He used the metaphor of a river to make his point. Most of the time, the river flows continuously, smoothly incorporating its tributaries, but sometimes, after a storm, it floods and breaks its banks.

Drawing on his Italian predecessor Machiavelli, Pareto identified two types of elite rulers. The first, whom he called the “foxes”, are those who dominate mainly through combinazioni (“combination”): deceit, cunning, manipulation and co-optation. Their rule is characterised by decentralisation, plurality and scepticism, and they are uneasy with the use of force. “Lions”, on the other hand, are more conservative. They emphasise unity, homogeneity, established ways, the established faith, and rule through small, centralised and hierarchical bureaucracies, and they are far more at ease with the use of force than the devious foxes. History is the slow swing of the pendulum from one type of elite to the other, from foxes to lions and back again.

The relevance of Pareto’s theories to the world today is clear. After a period of foxes in power, the lions are back with renewed vigour. Donald Trump, as his behaviour during the US presidential campaign confirmed, is perfectly at ease with the use of intimidation and violence. He claimed that he wants to have a wall built between the United States and Mexico. His mooted economic policies are largely based on protectionism and tariffs. Regardless of his dubious personal ethics – a classic separation between the elite and the people – he stands for the traditional (white) American way of life and religion.

This is in stark contrast to the Obama administration and the Cameron government, both of which, compared to what has come since the votes for Trump and Brexit, were relatively open and liberal. Pareto’s schema goes beyond the left/right divide; the whole point of his Systèmes socialistes was to demonstrate that Marxism, as a secular religion, signalled a return to faith, and thus the return of the lions in politics.

In today’s context, the foxes are the forces of globalisation and liberalism – in the positive sense of developing an open, inter­connected and tolerant world; and in the negative sense of neoliberalism and the dehumanising extension of an economic calculus to all aspects of human life. The lions represent the reaction, centring themselves in the community, to which they may be more attentive, but bringing increased xenophobia, intolerance and conservatism. For Pareto, the lions and foxes are two different types of rule, both with strengths and weaknesses. Yet the elite is always composed of the two elements. The question is: which one dominates at any given time?

What we know of Theresa May’s government suggests that she runs a tight ship. She has a close – and closed – group of confidants, and she keeps a firm grip on the people under her. She is willing to dispense with parliament in her negotiation of Brexit, deeming it within the royal prerogative. Nobody yet knows her plan.

The European Union is a quintessentially foxlike project, based on negotiation, compromise and combination. Its rejection is a victory of the lions over the foxes. The lions are gaining prominence across the Western world, not just in Trumpland and Brexit Britain. Far-right movements have risen by rejecting the EU. It should come as no surprise that many of these movements (including Trump in the US) admire Vladimir Putin, at least for his strongman style.

Asia hasn’t been spared this movement, either. After years of tentative openness in China, at least with the economy, Xi Jinping has declared himself the “core” leader, in the mould of the previous strongmen Mao Zedong and Deng Xiaoping. Japan’s prime minister, Shinzo Abe, has also hardened his stance, and he was the first world leader to meet with President-Elect Donald Trump. Narendra Modi in India and Rodrigo Duterte in the Philippines are in the same mould, the latter coming to power on the back of promising to kill criminals and drug dealers. After the failed coup against him in July, Recep Tayyip Erdogan has also been cracking down on Turkey.

In Les systèmes socialistes, Pareto elaborated on how a new elite replaces the old. A, the old elite, would be challenged by B, the new, in alliance with C, the people. B would win the support of C by making promises that, once in power, it wouldn’t keep. If that sounds like the behaviour of most politicians, that is because it probably is. But what Pareto was pointing out was how, in its struggle for power, the new elite politicised groups that were not political before.

What we know of Trump supporters and Brexiteers is that many feel disenfranchised: the turnout in the EU referendum could not have been greater than in the 2015 general election otherwise, and significant numbers of those who voted for Trump had never voted before. There is no reason to think that they, too, won’t be betrayed by the new leaders they helped to bring to power.

In the last years of his life, Pareto offered a commentary on Italy in the 1920s. He denounced the state’s inability to enforce its decisions and the way that Italians spent their time flaunting their ability to break the law and get away with it. He coined the phrase “demagogic plutocracy” to characterise the period, in which the rich ruled behind a façade of democratic politics. He thought this particularly insidious for two reasons: those in power were more interested in siphoning off wealth for their personal ends than encouraging the production of new wealth, and consequently undermined national prosperity (remember Pareto’s training as an economist); and, as the demagogic elites govern through deceit and cunning, they are able to mask their rule for longer periods.

Much has been made of Trump’s “populism”, but the term “demagogic plutocrat” seems particularly apt for him, too: he is a wealthy man who will advance the interests of his small clique to the detriment of the well-being of the nation, all behind the smokescreen of democratic politics.

There are other ways in which Pareto can help us understand our predicament. After all, he coined the 80/20 rule, of which we hear an intensified echo in the idea of “the One Per Cent”. Trump is a fully paid-up member of the One Per Cent, a group that he claims to be defending the 99 Per Cent from (or, perhaps, he is an unpaid-up member, given that what unites the One Per Cent is its reluctance to pay taxes). When we perceive the natural inequality of the distribution of resources as expressed through Pareto’s “power law”, we are intellectually empowered to try to do something about it.

Those writings on 1920s Italy landed Pareto in trouble, as his theory of the circulation of elites predicted that a “demagogic plutocracy”, dominated by foxes, would necessarily make way for a “military plutocracy”, this time led by lions willing to restore the power of the state. In this, he was often considered a defender of Mussolini, and Il Duce certainly tried to make the best of that possibility by making Pareto a senator. Yet there is a difference between prediction and endorsement, and Pareto, who died in 1923, had already been living as a recluse in Céligny in Switzerland for some time – earning him the nickname “the hermit of Céligny” – with only his cats for company, far removed from day-to-day Italian politics. He remained a liberal to his death, content to stay above the fray.

Like all good liberals, Pareto admired Britain above all. As an economist, he had vehemently defended its system of free trade in the face of outraged opposition in Italy. He also advocated British pluralism and tolerance. Liberalism is important here: in proposing to set up new trade barriers and restrict freedom of movement, exacerbated by their more or less blatant xenophobia, Trump and Brexit challenge the values at the heart of the liberal world.

What was crucial for Pareto was that new elites would rise and challenge the old. It was through the “circulation of elites” that history moved. Yet the fear today is that history has come to a standstill, that elites have ­become fossilised. Electors are fed up with choosing between the same old candidates, who seem to be proposing the same old thing. No wonder people are willing to try something new.

This fear of the immobility of elites has been expressed before. In 1956, the American sociologist C Wright Mills published The Power Elite. The book has not been out of print since. It is thanks to him that the term was anglicised and took on the pejorative sense it has today. For Mills, Cold War America had come to be dominated by a unified political, commercial and military elite. With the 20th century came the growth of nationwide US corporations, replacing the older, more self-sufficient farmers of the 19th century.

This made it increasingly difficult to ­distinguish between the interests of large US companies and those of the nation as a whole. “What’s good for General Motors,” as the phrase went, “is good for America.” As a result, political and commercial interests were becoming ever more intertwined. One had only to add the Cold War to the mix to see how the military would join such a nexus.

Mills theorised what President Dwight D Eisenhower denounced in his January 1961 farewell speech as the “military-industrial complex” (Eisenhower had wanted to add the word “congressional”, but that was thought to be too risky and was struck out of the speech). For Mills, the circulation of elites – a new elite rising to challenge the old – had come to an end. If there was any circulation at all, it was the ease with which this new power elite moved from one part of the elite to the other: the “revolving door”.

The Cold War is over but there is a similar sense of immobility at present concerning the political elite. Must one be the child or wife of a past US president to run for that office? After Hillary Clinton, will Chelsea run, too? Must one have gone to Eton, or at least Oxford or Cambridge, to reach the cabinet? In France is it Sciences Po and Éna?

The vote for Brexit, Trump and the rise of the far right are, beyond doubt, reactions to this sentiment. And they bear out Pareto’s theses: the new elites have aligned themselves with the people to challenge the old elites. The lions are challenging the foxes. Needless to say, the lions, too, are prototypically elites. Trump is a plutocrat. Boris Johnson, the co-leader of the Leave campaign, is as “establishment” as they come (he is an Old Etonian and an Oxford graduate). Nigel Farage is a public-school-educated, multimillionaire ex-stockbroker. Marine Le Pen is the daughter of Jean-Marie Le Pen. Putin is ex-KGB.

Pareto placed his hopes for the continuing circulation of elites in technological, economic and social developments. He believed that these transformations would give rise to new elites that would challenge the old political ruling class.

We are now living through one of the biggest ever technological revolutions, brought about by the internet. Some have argued that social media tipped the vote in favour of Brexit. Arron Banks’s Leave.EU website relentlessly targeted disgruntled blue-collar workers through social media, using simple, sometimes grotesque anti-immigration messages (as a recent profile of Banks in the New Statesman made clear) that mimicked the strategies of the US hard right.

Trump’s most vocal supporters include the conspiracy theorist Alex Jones, who has found the internet a valuable tool for propagating his ideas. In Poland, Jarosław Kaczynski, the leader of the Law and Justice party, claims that the Russian plane crash in 2010 that killed his twin brother (then the country’s president) was a political assassination, and has accused the Polish prime minister of the time, Donald Tusk, now the president of the European Council, of being “at least morally” responsible. (The official explanation is that the poorly trained pilots crashed the plane in heavy fog.)

It need not be like this. Silicon Valley is a world unto itself, but when some of its members – a new technological elite – start to play a more active role in politics, that might become a catalyst for change. In the UK, it has been the legal, financial and technological sectors that so far have led the pushback against a “hard” Brexit. And we should not forget how the social movements that grew out of Occupy have already been changing the nature of politics in many southern European countries.

The pendulum is swinging back to the lions. In some respects, this might be welcome, because globalisation has left too many behind and they need to be helped. However, Pareto’s lesson was one of moderation. Both lions and foxes have their strengths and weaknesses, and political elites are a combination of the two, with one element dominating temporarily. Pareto, as he did in Italy in the 1920s, would have predicted a return of the lions. But as a liberal, he would have cautioned against xenophobia, protectionism and violence.

If the lions can serve as correctives to the excesses of globalisation, their return is salutary. Yet the circulation of elites is a process more often of amalgamation than replacement. The challenge to liberal politics is to articulate a balance between the values of an open, welcoming society and of one that takes care of its most vulnerable members. Now, as ever, the task is to find the balance between the lions and the foxes. l
