Has global warming stopped?

Global warming stopped? Surely not. What heresy is this? Haven’t we been told that the science of global warming is settled beyond doubt and that all that’s left to the so-called sceptics is the odd errant glacier that refuses to melt?

Aren’t we told that if we don’t act now rising temperatures will render most of the surface of the Earth uninhabitable within our lifetimes? But as we digest these apocalyptic comments, read the recent IPCC’s Synthesis report that says climate change could become irreversible. Witness the drama at Bali as news emerges that something is not quite right in the global warming camp.

With only few days remaining in 2007, the indications are the global temperature for this year is the same as that for 2006 – there has been no warming over the 12 months.

But is this just a blip in the ever upward trend you may ask? No.

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.

In principle the greenhouse effect is simple. Gases like carbon dioxide present in the atmosphere absorb outgoing infrared radiation from the earth’s surface causing some heat to be retained.

Consequently an increase in the atmospheric concentration of greenhouse gases from human activities such as burning fossil fuels leads to an enhanced greenhouse effect. Thus the world warms, the climate changes and we are in trouble.

The evidence for this hypothesis is the well established physics of the greenhouse effect itself and the correlation of increasing global carbon dioxide concentration with rising global temperature. Carbon dioxide is clearly increasing in the Earth’s atmosphere. It’s a straight line upward. It is currently about 390 parts per million. Pre-industrial levels were about 285 ppm. Since 1960 when accurate annual measurements became more reliable it has increased steadily from about 315 ppm. If the greenhouse effect is working as we think then the Earth’s temperature will rise as the carbon dioxide levels increase.

But here it starts getting messy and, perhaps, a little inconvenient for some. Looking at the global temperatures as used by the US National Oceanic and Atmospheric Administration, the UK’s Met Office and the IPCC (and indeed Al Gore) it’s apparent that there has been a sharp rise since about 1980.

The period 1980-98 was one of rapid warming – a temperature increase of about 0.5 degrees C (CO2 rose from 340ppm to 370ppm). But since then the global temperature has been flat (whilst the CO2 has relentlessly risen from 370ppm to 380ppm). This means that the global temperature today is about 0.3 deg less than it would have been had the rapid increase continued.

For the past decade the world has not warmed. Global warming has stopped. It’s not a viewpoint or a sceptic’s inaccuracy. It’s an observational fact. Clearly the world of the past 30 years is warmer than the previous decades and there is abundant evidence (in the northern hemisphere at least) that the world is responding to those elevated temperatures. But the evidence shows that global warming as such has ceased.

The explanation for the standstill has been attributed to aerosols in the atmosphere produced as a by-product of greenhouse gas emission and volcanic activity. They would have the effect of reflecting some of the incidental sunlight into space thereby reducing the greenhouse effect. Such an explanation was proposed to account for the global cooling observed between 1940 and 1978.

But things cannot be that simple. The fact that the global temperature has remained unchanged for a decade requires that the quantity of reflecting aerosols dumped put in our atmosphere must be increasing year on year at precisely the exact rate needed to offset the accumulating carbon dioxide that wants to drive the temperature higher. This precise balance seems highly unlikely. Other explanations have been proposed such as the ocean cooling effect of the Interdecadal Pacific Oscillation or the Atlantic Multidecadal Oscillation.

But they are also difficult to adjust so that they exactly compensate for the increasing upward temperature drag of rising CO2. So we are led to the conclusion that either the hypothesis of carbon dioxide induced global warming holds but its effects are being modified in what seems to be an improbable though not impossible way, or, and this really is heresy according to some, the working hypothesis does not stand the test of data.

It was a pity that the delegates at Bali didn’t discuss this or that the recent IPCC Synthesis report did not look in more detail at this recent warming standstill. Had it not occurred, or if the flatlining of temperature had occurred just five years earlier we would have no talk of global warming and perhaps, as happened in the 1970’s, we would fear a new Ice Age! Scientists and politicians talk of future projected temperature increases. But if the world has stopped warming what use these projections then?

Some media commentators say that the science of global warming is now beyond doubt and those who advocate alternative approaches or indeed modifications to the carbon dioxide greenhouse warming effect had lost the scientific argument. Not so.

Certainly the working hypothesis of CO2 induced global warming is a good one that stands on good physical principles but let us not pretend our understanding extends too far or that the working hypothesis is a sufficient explanation for what is going on.

I have heard it said, by scientists, journalists and politicians, that the time for argument is over and that further scientific debate only causes delay in action. But the wish to know exactly what is going on is independent of politics and scientists must never bend their desire for knowledge to any political cause, however noble.

The science is fascinating, the ramifications profound, but we are fools if we think we have a sufficient understanding of such a complicated system as the Earth’s atmosphere’s interaction with sunlight to decide. We know far less than many think we do or would like you to think we do. We must explain why global warming has stopped.

Why Jeremy Corbyn is a new leader for the New Times

In an inspired election campaign, he confounded his detractors and showed that he was – more than any other leader – in tune with the times.

There have been two great political turning points in postwar Britain. The first was in 1945 with the election of the Attlee government. Driven by a popular wave of determination that peacetime Britain would look very different from the mass unemployment of the 1930s, and built on the foundations of the solidaristic spirit of the war, the Labour government ushered in full employment, the welfare state (including the NHS) and nationalisation of the basic industries, notably coal and the railways. It was a reforming government the like of which Britain had not previously experienced in the first half of the 20th century. The popular support enjoyed by the reforms was such that the ensuing social-democratic consensus was to last until the end of the 1970s, with Tory as well as Labour governments broadly operating within its framework.

During the 1970s, however, opposition to the social-democratic consensus grew steadily, led by the rise of the radical right, which culminated in 1979 in the election of Margaret Thatcher’s first government. In the process, the Thatcherites redefined the political debate, broadening it beyond the rather institutionalised and truncated forms that it had previously taken: they conducted a highly populist campaign that was for individualism and against collectivism; for the market and against the state; for liberty and against trade unionism; for law and order and against crime.

These ideas were dismissed by the left as just an extreme version of the same old Toryism, entirely failing to recognise their novelty and therefore the kind of threat they posed. The 1979 election, followed by Ronald Reagan’s US victory in 1980, began the neoliberal era, which remained hegemonic in Britain, and more widely in the West, for three decades. Tory and Labour governments alike operated within the terms and by the logic of neoliberalism. The only thing new about New Labour was its acquiescence in neoliberalism; even in this sense, it was not new but derivative of Thatcherism.

The financial crisis of 2007-2008 marked the beginning of the end of neoliberalism. Unlike the social-democratic consensus, which was undermined by the ideological challenge posed by Thatcherism, neoliberalism was brought to its knees not by any ideological alternative – such was the hegemonic sway of neoliberalism – but by the biggest financial crisis since 1931. This was the consequence of the fragility of a financial sector left to its own devices as a result of sweeping deregulation, and the corrupt and extreme practices that this encouraged.

The origin of the crisis lay not in the Labour government – complicit though it was in the neoliberal indulgence of the financial sector – but in the deregulation of the banking sector on both sides of the Atlantic in the 1980s. Neoliberalism limped on in the period after 2007-2008 but as real wages stagnated, recovery proved a mirage, and, with the behaviour of the bankers exposed, a deep disillusionment spread across society. During 2015-16, a populist wave of opposition to the establishment engulfed much of Europe and the United States.

Except at the extremes – Greece perhaps being the most notable example – the left was not a beneficiary: on the contrary it, too, was punished by the people in the same manner as the parties of the mainstream right were. The reason was straightforward enough. The left was tarnished with the same brush as the right: almost everywhere social-democratic parties, albeit to varying degrees, had pursued neoliberal policies. Bill Clinton and Tony Blair became – and presented themselves as – leaders of neoliberalism and as enthusiastic advocates of a strategy of hyper-globalisation, which resulted in growing inequality. In this fundamental respect these parties were more or less ­indistinguishable from the right.

***

The first signs of open revolt against New Labour – the representatives and evangelists of neoliberal ideas in the Labour Party – came in the aftermath of the 2015 ­election and the entirely unpredicted and overwhelming victory of Jeremy Corbyn in the leadership election. Something was happening. Yet much of the left, along with the media, summarily dismissed it as a revival of far-left entryism; that these were for the most part no more than a bunch of Trots. There is a powerful, often overwhelming, tendency to see new phenomena in terms of the past. The new and unfamiliar is much more difficult to understand than the old and familiar: it requires serious intellectual effort and an open and inquiring mind. The left is not alone in this syndrome. The right condemned the 2017 Labour Party manifesto as a replica of Labour’s 1983 manifesto. They couldn’t have been more wrong.

That Corbyn had been a veteran of the far left for so long lent credence to the idea that he was merely a retread of a failed past: there was nothing new about him. In a brilliant election campaign, Corbyn not only gave the lie to this but also demonstrated that he, far more than any of the other party leaders, was in tune with the times, the candidate of modernity.

Crises, great turning points, new conjunctures, new forms of consciousness are by definition incubators of the new. That is one of the great sources of their fascination. We can now see the line of linkage between the thousands of young people who gave Corbyn his overwhelming victory in the leadership election in 2015 and the millions of young people who were enthused by his general election campaign in 2017. It is no accident that it was the young rather than the middle-aged or the seniors who were in the vanguard: the young are the bearers and products of the new, they are the lightning conductors of change. Their elders, by contrast, are steeped in old ways of thinking and doing, having lived through and internalised the values and norms of neoliberalism for more than 30 years.

Yet there is another, rather more important aspect to how we identify the new, namely the way we see politics and how politics is conceived. Electoral politics is a highly institutionalised and tribal activity. There have been, as I argued earlier, two great turning points in postwar politics: the social-democratic era ushered in by the 1945 Labour government and the neoliberal era launched by the Tory government in 1979.

The average Tory MP or activist, no doubt, would interpret history primarily in terms of Tory and Labour governments; Labour MPs and activists would do similarly. But this is a superficial reading of politics based on party labels which ignores the deeper forces that shape different eras, generate crises and result in new paradigms.

Alas, most political journalists and columnists are afflicted with the same inability to distinguish the wood (an understanding of the deeper historical forces at work) from the trees (the day-to-day manoeuvring of parties and politicians). In normal times, this may not be so important, because life continues for the most part as before, but at moments of great paradigmatic change it is absolutely critical.

If the political journalists, and indeed the PLP, had understood the deeper forces and profound changes now at work, they would never have failed en masse to rise above the banal and predictable in their assessment of Corbyn. Something deep, indeed, is happening. A historical era – namely, that of neoliberalism – is in its death throes. All the old assumptions can no longer be assumed. We are in new territory: we haven’t been here before. The smart suits long preferred by New Labour wannabes are no longer a symbol of success and ambition but of alienation from, and rejection of, those who have been left behind; who, from being ignored and dismissed, are in the process of moving to the centre of the political stage.

Corbyn, you may recall, was instantly rejected and ridiculed for his sartorial style, and yet we can now see that, with a little smartening, it conveys an authenticity and affinity with the times that made his style of dress more or less immune from criticism during the general election campaign. Yet fashion is only a way to illustrate a much deeper point.

The end of neoliberalism, once so hegemonic, so commanding, is turning Britain on its head. That is why – extraordinary when you think about it – all the attempts by the right to dismiss Corbyn as a far-left extremist failed miserably, even proved counterproductive, because that was not how people saw him, not how they heard him. He was speaking a language and voicing concerns that a broad cross-section of the public could understand and identify with.

***

The reason a large majority of the PLP was opposed to Corbyn, desperate to be rid of him, was because they were still living in the neoliberal era, still slaves to its ideology, still in thrall to its logic. They knew no other way of thinking or political being. They accused Corbyn of being out of time when in fact it was most of the PLP – not to mention the likes of Mandelson and Blair – who were still imprisoned in an earlier historical era. The end of neoliberalism marks the death of New Labour. In contrast, Corbyn is aligned with the world as it is rather than as it was. What a wonderful irony.

Corbyn’s success in the general election requires us to revisit some of the assumptions that have underpinned much political commentary over the past several years. The turmoil in Labour ranks and the ridiculing of Corbyn persuaded many, including on the left, that Labour stood on the edge of the abyss and that the Tories would continue to dominate for long into the future. With Corbyn having seized the political initiative, the Tories are now cast in a new light. With Labour in the process of burying its New Labour legacy and addressing a very new conjuncture, then the end of neoliberalism poses a much more serious challenge to the Tories than it does the Labour Party.

The Cameron/Osborne leadership was still very much of a neoliberal frame of mind, not least in their emphasis on austerity. It would appear that, in the light of the new popular mood, the government will now be forced to abandon austerity. Theresa May, on taking office, talked about a return to One Nation Toryism and the need to help the worst-off, but that has never moved beyond rhetoric: now she is dead in the water.

Meanwhile, the Tories are in fast retreat over Brexit. They held a referendum over the EU for narrowly party reasons which, from a national point of view, was entirely unnecessary. As a result of the Brexit vote, the Cameron leadership was forced to resign and the Brexiteers took de facto command. But now, after the election, the Tories are in headlong retreat from anything like a “hard Brexit”. In short, they have utterly lost control of the political agenda and are being driven by events. Above all, they are frightened of another election from which Corbyn is likely to emerge as leader with a political agenda that will owe nothing to neoliberalism.

Apart from Corbyn’s extraordinary emergence as a leader who understands – and is entirely comfortable with – the imperatives of the new conjuncture and the need for a new political paradigm, the key to Labour’s transformed position in the eyes of the public was its 2017 manifesto, arguably its best and most important since 1945. You may recall that for three decades the dominant themes were marketisation, privatisation, trickle-down economics, the wastefulness and inefficiencies of the state, the incontrovertible case for hyper-globalisation, and bankers and financiers as the New Gods.

Labour’s manifesto offered a very different vision: a fairer society, bearing down on inequality, a more redistributive tax system, the centrality of the social, proper funding of public services, nationalisation of the railways and water industry, and people as the priority rather than business and the City. The title captured the spirit – For the Many Not the Few. Or, to put in another way, After Neoliberalism. The vision is not yet the answer to the latter question, but it represents the beginnings of an answer.

Ever since the late 1970s, Labour has been on the defensive, struggling to deal with a world where the right has been hegemonic. We can now begin to glimpse a different possibility, one in which the left can begin to take ownership – at least in some degree – of a new, post-neoliberal political settlement. But we should not underestimate the enormous problems that lie in wait. The relative economic prospects for the country are far worse than they have been at any time since 1945. As we saw in the Brexit vote, the forces of conservatism, nativism, racism and imperial nostalgia remain hugely powerful. Not only has the country rejected continued membership of the European Union, but, along with the rest of the West, it is far from reconciled with the new world that is in the process of being created before our very eyes, in which the developing world will be paramount and in which China will be the global leader.

Nonetheless, to be able to entertain a sense of optimism about our own country is a novel experience after 30 years of being out in the cold. No wonder so many are feeling energised again.
