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.

Jeremy Corbyn and the paranoid style

The Labour leader’s team has a bunker mentality, and their genius has been to extend that bunker to accommodate tens of thousands of their followers. Within that bubble, every failure becomes a victory.

 

There was an odd moment on the BBC last summer, during Jeremy Corbyn’s first leadership campaign. A reporter had asked him a simple question about nationalisation: “Where did you get these words from?” he snapped. “Has somebody been feeding you this stuff?” 

At the time I was taken aback, but before long the campaign would become defined by paranoia, manifested in its leader as an extreme suspicion of “mainstream media”, and in its supporters as a widespread belief that establishment forces were conspiring to “fix” the Labour leadership contest, the so-called #LabourPurge.

This summer, Corbyn is fighting another leadership election. The main focus of his campaign so far has been an attempt to paint his rival Owen Smith as a “Big Pharma shill”, while Corbyn’s most influential supporter, Unite’s Len McCluskey, has claimed that MI5 are waging a dirty tricks campaign against the Leader of the Opposition. On stage Corbyn has attacked national media for failing to cover a parish council by-election.  

Corbyn’s time as Labour leader has been marked by an extraordinary surge of paranoia and conspiracy theory on the left. The sheer intensity of it, combined with some of his supporters’ glassy-eyed denial of reality and desire to “purge” the party unfaithful, has led some to compare Corbynism to a cult or a religious movement. Unfortunately, the problem goes much deeper. Corbyn didn’t create or lead a movement; he followed one.

In the last few years, a new breed of hyperbolic pundits has emerged on left-wing social media who embody what Richard Hofstadter called “The Paranoid Style” in politics, “a sense of heated exaggeration, suspiciousness, and conspiratorial fantasy”.

Hofstadter’s 1964 essay was inspired by McCarthyism, but the Paranoid Style as a political and psychological phenomenon has been with us for as long as modern politics. Of course conspiracies and misdeeds can happen, but the Paranoid Style builds up an apocalyptic vision of a future driven entirely by dark conspiracies. The NHS won’t just be a bit worse; it will be destroyed in 24 hours. Opponents aren’t simply wrong, but evil incarnate; near-omnipotent super-villains control the media, the banks, even history itself. Through most of history, movements like this have remained at the fringes of politics; and when they move into the mainstream bad things tend to happen.

To pick one example among many, science broadcaster Marcus Chown’s Twitter feed is full of statements that fall apart at the slightest touch. We learn that billionaires control 80 per cent of the media – they don’t. We learn that the BBC were “playing down” the Panama Papers story, tweeted on a day when it led the TV news bulletins and was the number one story on their news site.  We learn that the Tories are lying when they say they’ve increased spending on the NHS. As FullFact report, the Tories have increased NHS spending in both absolute and real terms. We learn via a retweet that Labour were ahead of the Conservatives in polling before a leadership challengethey weren’t.

The surprise Conservative majority in last year’s election shocked the left to the core, and seemed to push this trend into overdrive. Unable to accept that Labour had simply lost arguments over austerity, immigration and the economy, people began constructing their own reality, pasting out of context quotes and dubious statistics over misleading charts and images. Falsehoods became so endemic in left-wing social media that it’s now almost impossible to find a political meme that doesn’t contain at least one serious mistruth. Popular social media figures like Dr Eoin Clarke have even built up the idea that the election result itself was a gigantic fraud.

The problem with creating your own truth is that you have to explain why others can’t – or won’t – see it. One answer is that they’re the unwitting stooges of an establishment conspiracy that must involve the “mainstream media”, a belief that seems more plausible in the wake of scandals over expense claims and phone-hacking. Voters can’t be expressing genuine concerns, so they must have been brainwashed by the media.  

The left have long complained about the right-wing bias of the tabloid press with some justification, but in recent years the rage of a hardcore minority has become increasingly focused on the BBC. “Why aren’t the BBC covering X” is a complaint heard daily, with X nearly always being some obscure or unimportant protest or something that in fact the BBC did cover.  

Bewildered and infuriated by the BBC’s refusal to run hard-left soundbites as headlines, the paranoid left assume Auntie is involved in some sort of right-wing establishment plot. Public figures such as Laura Kuenssberg, the Corporation’s political editor, have been subjected to a campaign of near-permanent abuse from the left, much of it reeking of misogyny. By asking Labour figures questions as tough as those she routinely puts to Conservative politicians, she has exposed her true role as a “Tory propagandist whore”, a “fucking cunt bag”, or a “Murdoch puppet”.

This was the context in which Corbyn’s leadership campaign was fought, and with his own dislike of the media and love of a good conspiracy theorist, he swiftly became a figurehead for the paranoid left. Suddenly, the cranks and conspiracy theorists had a home in his Labour party; and they flocked to it in their tens of thousands. Of course most Corbynistas aren’t cranks, but an intense and vocal minority are, and they have formed a poisonous core at the heart of the cause.

The result is a Truther-style movement that exists in almost complete denial of reality. Polls showing double-digit leads for the Conservatives are routinely decried as the fabrications of sinister mainstream media figures. The local elections in May, which saw Corbyn’s Labour perform worse than most opposition leaders in recent history, triggered a series of memes insisting that results were just fine. Most bewildering of all is a conspiracy theory which insists that Labour MPs who quit the shadow cabinet and declared ‘no confidence’ in Corbyn were somehow orchestrated by the PR firm, Portland Communications.

The paranoid left even has its own news sources. The Canary manages, without irony, to take the worst traits of the tabloids, from gross bias to the misreporting of a suicide note, and magnify them to create pages of pro-Corbyn propaganda that are indistinguishable from parody. On Facebook, Corbyn has more followers than the Labour Party itself. Fan groups filter news of Corbyn and his enemies so effectively that in one Facebook group I polled, more than 80 per cent of respondents thought Corbyn would easily win a general election.

This kind of thinking tips people over a dangerous threshold. Once you believe the conspiracy theories, once you believe you’ve been denied democracy by media manipulation and sinister establishment forces mounting dirty tricks campaigns, it becomes all too easy to justify bad behaviour on your own side. It starts with booing, but as the “oppressed” gain their voices the rhetoric and the behaviour escalate until the abuse becomes physical.

I’m prepared to believe Jeremy Corbyn when he says that he doesn’t engage in personal abuse. The problem is, he doesn’t have to. His army of followers are quite happy to engage in abuse on his behalf, whether it’s the relentless abuse of journalists, or bricks tossed through windows, or creating what more than 40 women MPs have described as a hostile and unpleasant environment

Supporters will point out that Jeremy Corbyn hasn’t asked for this to happen, and that in fact he’s made various statements condemning abuse. They’re not wrong, but they fail to grasp the point; that the irresponsible behaviour of Corbyn and his allies feeds into the atmosphere that leads inexorably to these kinds of abuses happening.

We see this in Corbyn’s unfounded attacks on media conspiracies, such as his absurd complaints about the lack of coverage of council elections. We see it in the shadow chancellor John McDonnell’s angry public jibes at Labour MPs. Surly aggression oozes out of the screen whenever a TV reporter asks Corbyn a difficult question. Then there’s the long history of revolutionary rhetoric – the praise for bombs and bullets, the happy engagement with the homophobic, the misogynistic, the anti-Semitic, the terrorist, in the name of nobler aims. 

Even the few statements Corbyn makes about abuse and bigotry are ambiguous and weak. Called upon to address anti-Semitism in the Labour party, he repeatedly abstracts to generic racism – in his select committee evidence on the topic, he mentioned racism 28 times, and anti-Semitism 25 times, while for his interviewers the ratio was 19 to 45. Called on to address the abuse of women MPs in the Labour Party, he broadened the topic to focus on abuse directed at himself, while his shadow justice secretary demanded the women show “respect” to party members. Corbyn’s speech is woolly at the best of times, but he and his allies seem determined to water down any call for their supporters to reform.   

Still, why reform when things are going so well? Taken at face value, Corbyn’s summer has been appalling. It began with the poor local election results, continued with Labour’s official position being defeated in the EU Referendum, and then saw the party’s leader lose a vote of no confidence, after which he was forced to watch the resignation of most of his shadow cabinet and then face a leadership challenge. Labour are polling terribly against Theresa May (who, admittedly, is in her honeymoon period), and the press are either hostile or find Corbyn impossible to work with.

If Corbyn were a conventional Leader of the Opposition these facts would be catastrophic, but he’s not and they’re not. To understand why, let’s look at some head-scratching quotes from leading Corbynistas. Jon Lansman, Chair of Momentum, was heavily mocked on Twitter recently for saying, “Democracy gives power to people, ‘Winning’ is the small bit that matters to political elites who want to keep power themselves.” The former BBC and Channel 4 journalist Paul Mason released a video clip suggesting Labour should be transformed into a “social movement”, along the lines of Occupy.  

These sentiments are echoed at the heart of Team Corbyn. Owen Smith claimed to have asked Corbyn and his Shadow Chancellor, John McDonnell, whether they were prepared to let the Labour party split. According to Smith, whose version of events was denied by John McDonnell but backed up by two other MPs, Corbyn refused to answer while McDonnell said “if that’s what it takes”. Many activists seem to hold the same view – Twitter is full of Momentum warriors quite happy to see the bulk of the PLP walk away, and unconcerned about their diminishing prospects of winning any election.

Which on the face of it makes no sense. Labour has 232 seats, considerably more than David Cameron inherited in 2005. Their opponent is an “unelected” Prime Minister commanding a majority of just twelve, who was a senior figure in the government that just caused Britain’s biggest crisis since the war, and is now forced to negotiate a deal that either cripples the economy or enrages millions of voters who were conned by her colleagues into believing they had won a referendum on immigration. Just before leaving office, George Osborne abandoned his budget surplus target – effectively conceding it was a political gambit all along.

A competent Labour leader, working with other parties and disaffected Remainian Tories, could be – should be - tearing lumps out of the government on a weekly basis. Majority government may be a distant prospect, but forcing the Tories into a coalition or removing them from government altogether by the next election is entirely achievable.  Yet it’s fair to say that many Corbynistas have little interest in seeing this scenario play out.

Which makes sense, because to these people Labour – real Labour – doesn’t have 232 seats, it has about 40. The others seats are occupied by “Red Tories” or, worse, “Blairites”. Since these groups are as much the enemy as the Tories are, exchanging one for the other is meaningless. The Corbynites could start their own party of course, but why do that when they can seize control of Labour’s infrastructure, short money and institutional donors. The only long-term strategy that makes sense is to “purify” Labour, and rebuild from the foundations up. That may mean another 10 or 20 years of Tory rule, but the achingly middle-class Corbynistas won’t be the ones to suffer from that.

Seen through that prism, Corbynism makes sense. A common theme among the dozens of resignation letters from former shadow ministers has been his apparent disinterest in opposition policy work. A recent Vice documentary showed his refusal to attack the Tories over the resignation of Iain Duncan Smith. Even Richard Murphy, a supportive economist who set out many of the basic principles of ‘Corbynomics’, lost patience in a recent blog post

“I had the opportunity to see what was happening inside the PLP. The leadership wasn’t confusing as much as just silent. There was no policy direction, no messaging, no direction, no co-ordination, no nothing. Shadow ministers appeared to have been left with no direction as to what to do. It was shambolic.”

So where are his attentions focused? Unnamed “insiders” quoted in the Mirror paint an all too feasible picture of a team that, “spent hours in ‘rambling’ meetings discussing possible plots against him and considered sending ‘moles’ to spy on his Shadow Cabinet.” That claim was given more weight by the recent controversy over Karie Murphy, Corbyn’s office manager, who allegedly entered the office of shadow minister Seema Malhotra without permission. Vice’s documentary, ‘The Outsider‘, showed Corbyn railing against the BBC, who he believed were ‘obsessed’ with undermining his leadership, and other journalists.

By all accounts, Corbyn’s team inhabit a bunker mentality, and their genius – intentional or otherwise – has been to use the ‘paranoid style’ to extend that bunker to accommodate tens of thousands of their followers. Within that bubble, every failure becomes a victory. Negative media coverage simply reinforces their sense of being under attack, and every bad poll or election disappointment becomes an opportunity to demonstrate the strength of their faith. Shadow cabinet resignations and condemnations reveal new ‘traitors’, justifying further paranoia and increasing the feeling of being under siege.

It’s terrible for a functioning opposition, but brilliant for forming a loyal hard-left movement, driving screaming protestors into CLP meetings, keeping uppity MPs in line with the prospect of more abuse or deselection, and ensuring that Corbyn will sign up enough supporters to win the leadership election by a landslide.  

Hofstadter wrote that ”the paranoid is a militant leader. He does not see social conflict as something to be mediated and compromised, in the manner of the working politician.” In the United States, Bernie Sanders was ultimately forced to compromise when Hillary Clinton won the Democrat nomination. The Bernie Corbyn & Jeremy Sanders Facebook group, hardcore loyalists to the end, immediately disowned him, and suggested the group change its name.

Corbyn need make no such compromise, which is his whole appeal. Those who expect him to step down after a general election defeat, or to compromise with the rest of the party to achieve greater success, have completely failed to understand what they’re dealing with. For Corbyn and his followers there is no compromise, only purity, and a Red Labour party with 50 MPs is better than a centrist party with 400. That is the reality of the movement that Labour and the left are facing, and it is catastrophic.
