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.

The Catalan cauldron

The prospect of the break-up of Spain poses yet another challenge to Europe.

As Britain prepares to mark the centenary of the bloodiest battle in the First World War, the Somme, in July, Spain is bracing itself for an even more traumatic anniversary. In July 2016 it will be 80 years since the start of a civil war that tore the country apart and continues to divide it today. In the four decades since the return of democracy in the mid-1970s, Spaniards slowly inched towards rejecting the extreme violence of the Francoist right (and elements of the opposing left) as well as acceptance of various federal arrangements to accommodate the national sentiments of the Basques and Catalans, whose aspirations Franco had so brutally suppressed. In recent years, however, this consensus has been called fundamentally into question, with severe potential consequences not only for the unity of Spain, but the cohesion of the European Union.

On 27 October 2015, after the Catalan elections, the new parliament in Barcelona passed a declaration requesting the start of a formal secession process from Spain, to be in place in 18 months. The immediate reaction of Spain’s prime minister, Mariano Rajoy, was to announce that the state was entitled “to use any available judicial and political mechanism contained in the constitution and in the laws to defend the sovereignty of the Spanish people and of the general interest of Spain”. The preamble to the constitution proclaims the Spanish nation’s desire to “protect all Spaniards and the peoples of Spain in exercising their ­human rights, their cultures and traditions, languages and institutions”. Probably the most disputed articles are 2 and 8, which state, respectively, that “the constitution is based upon the indissoluble unity of the Spanish nation, common and indivisible patria of all Spaniards” and that “the army’s mission is to guarantee the sovereignty and independence of Spain, to defend its territorial integrity and the constitutional set-up”. Rajoy’s implication was clear: the unity of the country would be maintained, if necessary by military means.

It was Madrid, however, that broke with the federal consensus some years ago and thus boosted secessionist sentiment in Catalonia. José María Aznar’s government (1996-2004) failed to respond to demands for greater autonomy for Catalonia, at a time when secession was not even mentioned. This led to an increasing awareness among Catalans that the federal transfer system within Spain left them with an annual deficit of 8 per cent of Catalonia’s GDP because of the financial arrangements established by the Spanish state, an issue aggravated by the effect of the global financial crisis. Catalan nationalism thus became a matter of not only the heart, but also the pocket. Even more important was the Spanish legal challenge to the Statute of Autonomy of Catalonia 2006 and its subsequent dilution, after it had been sanctioned by the Catalan parliament, and by both the Spanish congress of deputies and the senate, not to mention the Catalan people in a legally binding referendum.

According to the Spanish high court of justice, some of the statute’s content did not comply with the Spanish constitution. This outraged many Catalans, who could not understand how the newly approved statute – after following all the procedures and modifications requested by Spain’s political institutions and constitution – could still be challenged. Four years later, the Spanish high court finally delivered its verdict on 28 June 2010. It removed vital points from the Statute of Autonomy 2006 and declared them non-constitutional. All this led to a revival of Catalan nationalism, culminating in a symbolic, non-binding referendum in November 2014, which was boycotted by opponents and produced a majority of 80 per cent in favour of independence.

The roots of this antagonism go deep, to the civil war that broke out on 17-18 July 1936 when some sectors of the army rebelled against the legitimate government of the Second Republic. The rebels rejected democracy, the party system, separation between church and state, and the autonomy of Catalonia, the Basque Country and Galicia. Their primary objective was to re-establish “order” by eliminating all vestiges of communism and anarchism, then quite strong in some parts of Spain.

High on the list of General Franco’s targets was Catalan nationalism, which had been growing since the late 19th century. The industrialisation of Catalonia and the Basque Country left the most economically developed parts of the Spanish state politically subject to the less prosperous Castile. By the end of the 19th century and influenced by German Romanticism, la Renaixença – a movement for national and cultural renaissance – prompted demands for Catalan autonomy, first in the form of regionalism
and later in demands for a federal state.

Catalan nationalism did not emerge as a unified phenomenon. Diverse political ideologies and cultural influences gave rise to various types of nationalism, from the conservative nationalism of Jaime Balmes to the federalism of Francesc Pi i Margall, to the Catholic nationalism of Bishop Torres i Bages and the Catalan Marxism of Andreu Nin, among others. Catalonia enjoyed some autonomy under the administrative government of the Mancomunitat or “commonwealth” from 1913 onwards. This was halted by the 1923 coup d’état of the dictator Miguel Primo de Rivera. Autonomy was granted again during the Second Spanish Republic from 1931-39 – but abolished by Francisco Franco’s decree of 5 April 1938.

Franco’s victory led to the suppression of Catalan political institutions, the banning of the Catalan language and proscription of all the symbolic elements of Catalan identity, from the national flag (the Senyera) to the national anthem (“Els Segadors”). In February 1939, the institutions of the autonomous Generalitat went into exile in France. In 1940 the Gestapo arrested the president of the Generalitat, Lluís Companys, and handed him over to Spanish officials. He was interrogated and tortured in Madrid, then sent to Barcelona, where he was court-martialled and executed at Montjuïc Castle on 15 October 1940. The most important representatives of the democratic parties banned by the regime went into exile, or were imprisoned or executed. The authoritarian state designed by Franco crushed dissent and used brute power to suppress the historical nations included within its territory. The regime’s aim was to annihilate the Catalans and the Basques as nations.

***

After almost 40 years of Franco’s dictatorship, Catalonia recovered its government, the Generalitat, in 1977 – before the drafting of the Spanish constitution in 1978 – and sanctioned a new statute of autonomy in 1979. The 2006 statute was expected, at the time, to update and expand Catalans’ aspiration for further devolution within Spain: never secession.

At present, a renewed nostalgia and enthusiasm for Francoism can be found among some sections of the Spanish right. One of the main challenges of the newly democratic government from the mid-1970s onwards was to get rid of the symbols of Francoism that had divided Spaniards between “winners” and “losers” in the civil war. It was only in 2007 that the then prime minister, José Luis Rodríguez Zapatero, guided the Law of Historic Memory through parliament with the aim of removing hundreds of Fascist symbols reminiscent of the Franco era from public buildings. It also sought to make reparations to victims of the civil war and the ensuing dictatorship.

There still exist hundreds of other references to the Fascist regime, however, with streets, colleges and roads named after Franco and his generals. The most controversial of these is the Valle de los Caídos (“Valley of the Fallen”), near Madrid, commissioned by Franco as his final resting place. It supposedly honours the civil war dead, but is primarily a monument to the general and his regime, housing the graves of Franco and José Antonio Primo de Rivera, the founder of the fascist Falange political party. Roughly 450,000 people visit it every year, and while most of them are foreign tourists, groups of Falangists and supporters of the old regime who come to pay tribute to the dictator have frequented it. Nostalgics for Francoism, though still a small minority within modern Spain, are becoming vociferous. They find common ground with far-right-wing conservatism, particularly in their shared aversion to federalism.

On 3 August last year Artur Mas, the then president of Catalonia, called an extraordinary parliamentary election after all attempts to negotiate and agree on a legally binding referendum with the Spanish government failed. Supporters of independence immediately announced that the forthcoming Catalan elections would be regarded as a plebiscite on independence.

On a turnout of more than three-quarters of the electorate, supporters of outright independence gained 48 per cent of the vote, while those backing a unitary state secured 39 per cent. On 9 November 2015 the Catalan parliament formally declared the start of the process leading to building an independent Catalan state in the form of a republic. It also proclaimed the beginning of a participative, open, integrating and active citizens’ constituent process to lay the foundations for a future Catalan constitution. The Catalan government vowed to move forward with its secession process. Immediately, the Spanish Constitutional Court suspended the Catalan law setting out a path to independence and warned that defiance could lead to criminal charges.

Worse still for Madrid, secessionism is gaining strength not only in Catalonia but also in the Basque Country, whose premier, Iñigo Urkullu, demands a “legal consultation” on the northern region’s future in Spain. He supports a new statute for the Basque Country and defends its status as a nation in the EU. Similarly to Catalonia, the Basque Country has a distinct language and culture, and benefits from the so-called concierto económico, an advantageous financial deal with the Spanish state.

The Spanish government’s refusal to engage constructively with Catalan nationalism contrasts markedly with London’s more relaxed and ultimately more successful response to Scottish nationalist aspirations. The “Edinburgh Agreement” between the British Prime Minister and the then first minister of Scotland to allow a binding referendum on Scottish independence stands in sharp contrast to the Spanish government’s outright opposition to a similar vote in Catalonia. Basques and Catalans find deaf ears regarding further devolution and binding referendums on self-determination. This highlights the distance between various conceptions of democracy that coexist inside the European Union, rooted in the diverse political cultures of nations with varying historical backgrounds.

All this matters, not only to Spain but to the EU, because it is part of a broad trend across the continent. In mainland Europe, demands for self-determination are running strong in Flanders as well as parts of Spain. In turn, tensions between Italy and Austria over control of South Tyrol (Trentino Alto Adige, to the Italians) remain high, as do demands advanced by the South Tyrol­ean secessionist movement. Bavarian regionalism is critical of the present German (and European) political order. Further to that, modern Venetian nationalism and its long-standing demands for independence have prompted a renewal of Venetian as a language taught in schools and spoken by almost four million people.

Matters are now coming to a head. Catalonia and Spain are in flux following two inconclusive elections. In January, after a prolonged stand-off, the sitting Catalan president, Artur Mas, made way for a fellow nationalist, Carles Puigdemont. He was the first to take the oath of office without making the traditional oath of loyalty to the Spanish constitution and the king. Felipe VI, in turn, did not congratulate Puigdemont.

The new president has announced that he plans to draw up a constitution, to be voted on in a referendum “to constitute the Catalan Republic” at the end of an 18-month consultation process. Puigdemont’s strategy envisages not a dramatic unilateral declaration
of independence, but a more gradual process of disconnection in constant dialogue with the Spanish government and Catalan political parties. Let no one be deceived by this “softly-softly” approach: it is designed to culminate, in a year and a half, perhaps sooner, in a vote on establishing a separate, sovereign state of Catalonia.

Meanwhile, Spanish politics are in flux. The elections to the Cortes on 20 December 2015 resulted in a victory for Conservatism, but also the most fragmented Spanish parliament ever and, as yet, no government. Almost the only thing the Spanish parties can agree on is opposition to Catalan independence, yet even here there are divisions over whether more autonomy should be granted and what response to make to unilateral moves by the Catalans.

The stakes are high for both sides. By pressing too hard, too early, Catalan nationalists may provoke Madrid. This would be a mistake. Strategy is important and recent events in Catalonia will weaken the Catalans’ democratic, peaceful and legitimate desire to hold a referendum on independence. Likewise, a heavy-handed response from Madrid will not only destroy the residual bonds between centre and periphery in Spain, but put the central government in the dock internationally. A confrontation will also cut across the only possible solution to this and all other national conflicts within the eurozone, which is full continental political union. Full union would render the separation of Catalonia from Spain as irrelevant to the functioning of the EU, and the inhabitants of both areas, as the separation of West Virginia from Virginia proper in the United States today.

In a nightmare scenario, radicalisation and unrest could emerge in Catalonia, with division between Catalans and memories of the Spanish Civil War coming to the fore. In this context, it might become very difficult to prevent violence.

This is the last thing that Brussels wants to hear as it grapples with the euro crisis, Russian territorial revisionism, Islamist terror, the migrant question and the prospect of Brexit. A meltdown in Catalonia will create dilemmas for Europe, starting from problems with Schengen, and raise questions about continued membership of the EU. It will also work against Catalans’ expectations of receiving EU support in their quest for independence, as turmoil in Europe will prompt nation states to close ranks. The EU will not be expected to intervene, because this scenario would – at least initially – be defined as an “internal affair of Spain”. Conflict between Barcelona and Madrid would shatter one of Europe’s biggest member states.

In that event, the peninsula will become the hottest point in an emerging “arc of crisis” across the southern flank of the EU, stretching from Portugal across Spain, an Italy struggling along with everything else to cope with the flow of migrants, the troubled Balkans, to Greece, which is perpetually perturbed. This highlights yet another flaw in the EU. It has no institutional framework for dealing with Catalan demands to become a nation within the Union, or those of other populations. Merely insisting on Spanish state sovereignty will not make the problem go away for Brussels, or for Europe as a whole. This is a potential matter of life and death not only for Spaniards and Catalans, but perhaps for the EU itself.
