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.

A nervous breakdown in the body politic

Are we too complacent in thinking that the toxic brew of paranoia and populism that brought Hitler to power will never be repeated?

The conventional wisdom holds that “all that is necessary for the triumph of evil is that good men do nothing”, in Edmund Burke’s familiar phrase; but this is at best a half-truth. Studying the biography of a moral monster triumphantly unleashed on the political and international stage points us to another perspective, no less important. What is necessary for the triumph of evil is that the ground should have been thoroughly prepared by countless small or not-so-small acts of petty malice, unthinking prejudice and collusion. Burke’s axiom, though it represents a powerful challenge to apathy, risks crediting evil with too much of a life of its own: out there, there are evil agencies, hostile to “us”, and we (good men and women) must mobilise to resist.

No doubt; but mobilising intelligently demands being willing to ask what habits and assumptions, as well as what chances and conditions, have made possible the risk of evil triumphing. And that leads us into deep waters, to a recognition of how what we tolerate or ignore or underestimate opens the way for disaster, the ways in which we are at least half-consciously complicit. If this is not to be the silly we-are-all-guilty response that has rightly been so much mocked, nor an absolution for the direct agents of great horrors, it needs a careful and unsparing scrutiny of the processes by which cultures become corruptible, vulnerable to the agendas of damaged and obsessional individuals.

This can be uncomfortable. It raises the awkward issue of what philosophers have learned to call “moral luck” – the fact that some people with immense potential for evil don’t actualise it, because the circumstances don’t present them with the chance, and that some others who might have spent their lives in blameless normality end up supervising transports to Auschwitz. Or, to take a sharply contemporary example, that one Muslim youth from a disturbed or challenging background becomes a suicide bomber but another from exactly the same background doesn’t. It is as though there were a sort of diabolical mirror image for the biblical Parable of the Sower: some seeds grow and some don’t, depending on the ground they fall on, or what chance external stimulus touches them at critical moments.

If what interests us is simply how to assign individuals rapidly and definitively to the categories of sheep and goats, saved and damned, this is offensively frustrating. But if we recognise that evil is in important respects a shared enterprise, we may be prompted to look harder at those patterns of behaviour and interaction that – in the worst cases – give permission to those who are most capable of extreme destructiveness, and to examine our personal, political and social life in the light of this.

It would be possible to argue that the anti-Semitism of a lot of German culture – as of European Christian culture overall – was never (at least in the modern period) genocidal and obsessed with absolute racial purity; limited but real possibilities of integration were taken for granted, converts to Christianity were not disadvantaged merely because of their race, and so on. Yet the truth is that this cultural hinterland offered a foothold to the mania of Adolf Hitler; that it gave him just enough of the permission he needed to identify his society’s problems with this clearly definable “alien” presence. In his new book, Hitler: the Ascent, Volker Ullrich compellingly tells us once again that no one could have been under any illusion about Hitler’s general intentions towards the Jews from his very first appearance as a political figure, even if the detailed planning of genocide (lucidly traced in the late David Cesarani’s recent, encyclopaedic Final Solution) took some time to solidify. Yet so much of the German public heard Hitler’s language as the slightly exaggerated version of a familiar trope and felt able to treat it as at worst an embarrassing overstatement of a common, even a common-sense, view. One of the most disturbing things about this story is the failure of so many (inside and outside Germany) to grasp that Hitler meant what he said; and this failure in turn reinforced the delusion of those who thought they could use and then sideline Hitler.

To say that Hitler “meant what he said”, however, can be misleading. It is one of the repeated and focal themes in Ullrich’s book that Hitler was a brazen, almost compulsive liar – or, perhaps better, a compulsive and inventive actor, devising a huge range of dramatic roles for himself: frustrated artist, creative patron, philosopher-king (there is a fine chapter on the intellectual and artistic circle he assembled frequently at his Berchtesgaden residence), workers’ friend, martyr for his people (he constantly insinuated that he believed himself doomed to a tragic and premature death), military or economic messiah and a good deal else besides. His notorious outbursts of hysterical rage seem to have been skilfully orchestrated as instruments of intimidation (though this did not exactly indicate that he was otherwise predictable). Ullrich devotes a fair measure of attention to the literal staging of National Socialism, the architectural gigantism of Albert Speer which gave the Führer the sophisticated theatre he craved. In all sorts of ways, Hitler’s regime was a profoundly theatrical exercise, from the great public displays at Nuremberg and the replanning of Berlin to the various private fantasies enacted by him and his close associates (Göring above all), and from the emotional roller coaster he created for his circle to the dangerously accelerated rate of military-industrial expansion with which he concealed the void at the centre of the German economy.

Theatre both presupposes and creates a public. In the anxiety and despair of post-Versailles Germany, there was a ready audience for the high drama of Nazism, including its scapegoating of demonic enemies within and without. And in turn, the shrill pitch of Hitler’s quasi-liturgies normalised a whole set of bizarre and fantastic constructions of reality. A N Wilson’s challenging novel Winnie and Wolf, a fantasia on Hitler’s relations with Winifred Wagner, culminates in a scene at the end of the war where refugees and destitute citizens in Bayreuth raid the wardrobe of the opera house and wander the streets dressed in moth-eaten costumes; it is an unforgettable metaphor for one of the effects of Hitlerian theatre. Ullrich leaves his readers contemplating the picture of a vast collective drama centred on a personality that was not – as some biographers have suggested – something of a cipher, but that of a fantasist on a grand scale, endowed with a huge literal and metaphorical budget for staging his work.

All of this prompts questions about how it is that apparently sophisticated political systems succumb to corporate nervous breakdowns. It is anything but an academic question in a contemporary world where theatrical politics, tribal scapegoating and variegated confusions about the rule of law are increasingly in evidence. On this last point, it is still shocking to realise how rapidly post-Versailles Germany came to regard violent public conflict between heavily armed militias as almost routine, and this is an important background to the embittered negotiations later on around the relation between Hitler’s Sturmabteilung and the official organs of state coercion. Ullrich’s insightful account of a de facto civil war in Bavaria in the early 1920s makes it mercilessly plain that any pretensions to a state monopoly of coercion in Germany in this period were empty.

Yet the idea of such a state monopoly is in fact essential to anything that could be called a legitimate democracy. In effect, the polity of the Third Reich “privatised” coer­cion: again and again in Ullrich’s book, in the struggles for power before 1933, we see Nazi politicians successfully bidding for control of the mechanisms of public order in the German regions, and more or less franchising public order to their own agencies. A classical democratic political philosophy would argue that the state alone has the right to use force because the state is the guarantor of every community’s and every individual’s access to redress for injury or injustice. If state coercion becomes a tool for any one element in the social complex, it loses legitimacy. It is bound up with the rule of law, which is about something more than mere majority consent. One way of reading the rise of Hitler and National Socialism is as the steady and consistent normalising of illegitimate or partisan force, undermining any concept of an independent guarantee of lawfulness in society. It is the deliberate dissolution of the idea of a Rechtsstaat, a law-governed state order that can be recognised by citizens as organised for their common and individual good. Rule by decree, the common pattern of Nazi governmental practice, worked in harness with law enforcement by a force that was essentially a toxic hybrid, combining what was left of an independent police operation with a highly organised party militia system.

So, one of the general imperatives with which Hitler’s story might leave us is the need to keep a clear sense of what the proper work of the state involves. Arguments about the ideal “size” of the state are often spectacularly indifferent to the basic question of what the irreducible functions of state authority are – and so to the question of what cannot be franchised or delegated to non-state actors (it is extraordinary that we have in the UK apparently accepted without much debate the idea that prison security can be sold off to private interests). This is not the same as saying that privatisation in general leads to fascism; the issues around the limits to state direction of an economy are complex. However, a refusal to ask some fundamental questions about the limits of “franchising” corrodes the idea of real democratic legitimacy – the legitimacy that arises from an assurance to every citizen that, whatever their convictions or their purchasing power, the state is there to secure their access to justice. And, connected with this, there are issues about how we legislate: what are the proper processes of scrutiny for legislation, and how is populist and short-view legislation avoided? The Third Reich offers a masterclass in executive tyranny, and we need not only robust and intelligent counter-models, but a clear political theory to make sense of and defend those models.

Theatre has always been an aspect of the political. But there are different kinds of theatre. In ancient Athens, the annual Dionysia festival included the performance of tragedies that forced members of the audience to acknowledge the fragility of the political order and encouraged them to meditate on the divine interventions that set a boundary to vendetta and strife. Classical tragedy is, as political theatre, the exact opposite of Hitlerian drama, which repeatedly asserted the solid power of the Reich, the overcoming of weakness and division by the sheer, innate force of popular will as expressed through the Führer.

Contemporary political theatre is not – outside the more nakedly totalitarian states – a matter of Albert Speer-like spectacle and affirmation of a quasi-divine leader; but it is increasingly the product of a populist-oriented market, the parading of celebrities for popular approval, with limited possibilities for deep public discussion of policies advanced, and an assumption that politicians will be, above all, performers. It is not – to warn once again against cliché and exaggeration – that celebrity culture in politics is a short route to fascism. But a political theatre that never deals with the fragility of the context in which law and civility operate, that never admits the internal flaws and conflicts of a society, and never allows some corporate opening-up to the possibilities of reconciliation and reparation, is one that exploits, rather than resolves our anxieties. And, as such, it makes us politically weaker, more confused and fragmented.

The extraordinary mixture of farce and menace in Donald Trump’s campaign is a potent distillation of all this: a political theatre, divorced from realism, patience and human solidarity, bringing to the surface the buried poisons of a whole system and threatening its entire viability and rationality. But it is an extreme version of the way in which modern technology-and-image-driven communication intensifies the risks that beset the ideals of legitimate democracy.

And – think of Trump once again – one of the most seductively available tricks of such a theatre is the rhetoric of what could be called triumphant victimhood: we are menaced by such and such a group (Jews, mig­rants, Muslims, Freemasons, international business, Zionism, Marxism . . .), which has exerted its vast but covert influence to destroy us; but our native strength has brought us through and, given clear leadership, will soon, once and for all, guarantee our safety from these nightmare aliens.

This is a rhetoric that depends on ideas of collective guilt or collective malignity: plots ascribed to the agency of some dangerous minority are brandished in order to tarnish the name of entire communities. The dark legacy of much popular Christian language about collective Jewish guilt for the death of Jesus could be translated without much difficulty into talk about the responsibility of Jews for the violence and poverty afflicting Germans in the 1920s. (Shadows of the same myths still affect the way in which – as recent reports suggest – sinister, vague talk about Zionism and assumptions of a collective Jewish guilt for the actions of various Israeli politicians can become part of a climate that condones anti-Semitic bullying, or text messages saying “Hitler had a point”, on university campuses.)

Granted that there is no shortage of other candidates for demonic otherness in Europe and the United States (witness Trump’s language about Muslims and Mexicans), the specific and abiding lesson of Nazi anti-Semitism is the twofold recognition of the ease with which actually disadvantaged communities can be cast in the role of all-powerful subverters, and the way in which the path to violent exclusion of one kind or another can be prepared by cultures of casual bigotry and collective anxiety or self-pity, dramatised by high-temperature styles of media communication.

Marie Luise Knott’s recent short book Unlearning With Hannah Arendt (2014) revisits the controversy over Arendt’s notorious characterisation of the mindset of Nazism as “the banality of evil”, and brilliantly shows how her point is to do with the erosion in Hitlerian Germany of the capacity to think, to understand one’s agency as answerable to more than public pressure and fashion, to hold to notions of honour and dignity independent of status, convention or influence – but also, ultimately, the erosion of a sense of the ridiculous. The victory of public cliché and stereotype is, in Arendt’s terms, a protection against reality, “against the claim on our thinking attention that all events and facts make by virtue of their existence”, as she memorably wrote in The Life of the Mind. Hitler was committed to the destruction of anything that challenged the simple self-identity and self-justification of the race and the nation; hence, as Ullrich shows in an acutely argued chapter of Hitler: a Biography, the Führer’s venom against the churches, despite their (generally) embarrassingly lukewarm resistance to the horrors of the Reich. The problem was that the churches’ rationale entailed just that accountability to more than power and political self-identity that Nazi philosophy treated as absolute. They had grounds for thinking Nazism not only evil, but absurd. Perhaps, then, one of the more unexpected questions we are left with by a study of political nightmare such as Ullrich’s excellent book is how we find the resources for identifying the absurd as well as for clarifying the grounds of law and honour.

The threats now faced by “developed” democracy are not those of the 1920s and 1930s; whatever rough beasts are on their way are unlikely to have the exact features of Hitler’s distinctive blend of criminality and melodrama. But this does not mean that we shouldn’t be looking as hard as we can at the lessons to be learned from the collapse of political legality, the collective panics and myths, the acceptance of delusional and violent public theatre that characterised Hitler’s Germany. For evil to triumph, what is necessary is for societies to stop thinking, to stop developing an eye for the absurd as well as the corrupt in language and action, public or private.
