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 knows he can't do the job." What now for Labour and Britain's opposition?

Senior figures from all parties discuss the way forward: a new Labour leader, a new party or something else?

In the week beginning 13 March 2017, the Scottish National Party demanded a second referendum on indepen­dence, the Chancellor tore up his Budget and George Osborne was announced as the next editor of the London Evening Standard. One fact united these seemingly disparate events: the weakness of Her Majesty’s Opposition.

When Scotland’s First Minister, Nicola Sturgeon, addressed journalists at Bute House, her Edinburgh residence, she observed that Labour’s collapse entailed an extended period of Conservative rule. Such was the apparent truth of this statement that it went unchallenged.

Twenty minutes before Prime Minister’s Questions on 15 March, the Conservatives announced the abandonment of their planned rise in National Insurance for the self-employed. Their expectation that Jeremy Corbyn would be unable to profit was fulfilled. “Faced with an open goal, Jeremy picked up a tennis racket,” one Labour MP lamented of his leader’s performance. Rather than a threat, the government regards PMQs as an opportunity.

Two days later, Osborne was announced as the next editor of the Standard. “Frankly @George_Osborne will provide more effective opposition to the government than the current Labour Party,” the paper’s co-proprietor Evgeny Lebedev tweeted. His decision to hand the post to a Conservative MP was another mark of Labour’s marginalisation. In more politically competitive times, owners are warier of overt partisanship.

The Tories have a parliamentary majority of just 15 – the smallest of any single-party government since 1974 – but they enjoy a dominance out of all proportion to this figure. Nick Clegg, the Liberal Democrat former deputy prime minister, told me: “The fundamental pendulum swing of democracy, namely that the people in power are always worried that the other lot are going to hoof them out, has stopped.”

Labour is hardly a stranger to opposition: the party governed for just 20 years of the 20th century. But never in postwar history has it appeared so feeble. By-elections are usually relished by oppositions and feared by governments. But in Copeland in the north-west of England, a seat that had not returned a Conservative since 1931, the Tories triumphed over Labour. In recent polling the governing party has led by as much as 19 points and on one occasion it was leading in every age group, every social class and every region.

Corbyn’s MPs fear that were he to lead Labour into a general election, the attack dossier assembled by the Conservatives would push support as low as 20 per cent.

When David Miliband recently said that Labour was “further from power than at any stage in my lifetime”, he was being far too generous. After the forthcoming boundary changes, it could be left with as few as 150 seats: its worst performance since 1935.

The party’s plight was both predictable and predicted – the inevitable consequence of electing a leader who, by his own admission, lacked the requisite skills. “Now we made to make sure I don’t win,” Corbyn told supporters after he made the ballot in 2015. The lifelong backbencher stood with the intention of leading debate, not leading the party.

Neil Kinnock, Labour’s leader from 1983 to 1992, told me: “From the outset, I said that Jeremy [Corbyn] just can’t do the job . . . Now I think he knows that. He’s been a member of parliament for 34 years and will have a sense of self-examination. Both he and the people who work around him know that he just can’t do the job.”

Morale in the leader’s office has seldom been lower. “They’ve got the yips,” a Lab­our aide told me. Shortly after the Tories’ Budget U-turn, Corbyn’s director of strategy and communications, Seumas Milne, asked journalists whether there would be an early general election. He produced no evidence of any hope that Labour could win it.

Yet Corbyn’s leadership alone does not explain the crisis. In the early 1980s, when Labour was similarly enfeebled (but still strong in Scotland, unlike today), the creation of the Social Democratic Party provided hope. But the mere 23 seats won by the SDP-Liberal Alliance in 1983 (on 25.4 per cent of the vote, against Labour’s 209 seats from 27.6 per cent) acts as a permanent warning to those tempted to split.

With only nine MPs, the Liberal Democrats are too weak to function as an alternative opposition, despite their accelerating recovery. The third-largest party in the House of Commons – the SNP – is an exclusively Scottish force. The hegemony of the Nats, which cost Labour 40 seats in Scotland in 2015, has encouraged forecasts of perpetual Tory rule. “I don’t think there’s any way the Labour Party in this day and age can beat the Conservatives south of the border,” Clegg said.

To many eyes, the UK is being transformed into two one-party states: an SNP-led Scotland and a Conservative-led England. “The right-wing press have coalesced around Brexit and have transformed themselves from competitors into, in effect, a political cabal, which has such a paralysing effect on the political debate,” Clegg said. “You have a consistent and homogeneous drumbeat from the Telegraph, the Express, the Mail, the Sun, and so on.”

In this new era, the greatest influence on the government is being exercised from within the Conservative Party. “Where’s the aggravation? Where’s the heat coming from? Eighty hardline Brexiteers,” Anna Soubry, the pro-European former Conservative minister, told me. “They’re a party within a party and they are calling the shots. So where else is [May’s] heat? Fifteen Conservatives – people like me and the rest of them now. So who’s winning out there?”

Soubry added: “The right wing of the party flex their muscle against the only lead Remainer in the cabinet, Philip Hammond, for no other reason than to see him off. And that’s what they’ll do. They’ll pick them off one by one. These people are ruthless, this is their life’s work, and nobody and nothing is going to get in their way.”

Theresa May’s decision to pursue a “hard Brexit” – withdrawal from the EU single market and the customs union – is partly a policy choice; there is probably no other means by which the UK can secure significant control over European immigration. But the Prime Minister’s course is also a political choice. She recognised that the Conservatives’ formidable pro-Leave faction, whose trust she had to earn, as a Remainer, would accept nothing less.

***

The UK is entering the most complex negotiations it has undertaken since the end of the Second World War with the weakest opposition in living memory. Though some Tories relish an era of prolonged one-party rule, others are troubled by the democratic implications. Neil Carmichael MP, the chair of the Conservative Group for Europe, cited Disraeli’s warning: “No government can be long secure without a formidable opposition.” It was in Margaret Thatcher’s and Tony Blair’s pomp that calamitous decisions such as the poll tax and the invasion of Iraq were made. Governments that do not fear defeat frequently become their own worst enemy and, in turn, the public’s. The UK, with its unwritten constitution, its unelected upper chamber and its majoritarian voting system, is permanently vulnerable to elective dictatorships.

As they gasp at Labour’s self-destruction, politicians are assailed by Lenin’s question: “What is to be done?” Despite the baleful precedent of the SDP, some advocate a new split. In favour of following this path, they cite an increasingly promiscuous electorate, a pool of willing donors and “the 48 per cent” who voted Remain. Emmanuel Macron – the favourite to be elected president of France in May, who founded his own political movement, En Marche! – is another inspiration.

A week after the EU referendum, the Liberal Democrat leader, Tim Farron, was taken by surprise when a close ally of George Osborne approached him and suggested the creation of a new centrist party called “the Democrats” (the then chancellor had already pitched the idea to Labour MPs). “I’m all ears and I’m very positive about working with people in other parties,” Farron told me. But he said that the “most effective thing” he could do was to rebuild the Liberal Democrats.

When we spoke, Nick Clegg emphasised that “you’ve got to start with the ideas” but, strikingly, he did not dismiss the possibility of a new party. “You can have all sorts of endless, as I say, political parlour game discussions about whether you have different constellations or otherwise.”

Anna Soubry was still more positive about a new party, arguing: “If it could somehow be the voice of a moderate, sensible, forward-thinking, visionary middle way, with open minds – actually things which I’ve believed in all my life – better get on with it.”

However, Labour MPs have no desire to accept that the left’s supremacy is irreversible. But neither do they wish to challenge Corbyn. An MP distilled the new approach: “There is a strategy to give Jeremy [Corbyn] enough rope to hang himself. So it has not been about popping up in the media and criticising him in the way that colleagues did a year or so ago.” By giving him the space to fail on his own terms, rather than triggering another leadership contest, MPs hope that members will ultimately accept a change of direction.

Corbyn’s opponents acknowledge the risks of this approach.

“People are incredibly mindful of the fact that our brand is toxifying,” one told me. “As each day goes by, our plight worsens. Our position in the polls gets worse and the road back gets longer.”

Shadow cabinet ministers believe that Corbyn’s allies will never permit his departure until there is a viable successor. An increasingly influential figure is Karie Murphy, the director of the leader’s office and a close friend of Unite’s general secretary, Len McCluskey. “She’s holding Jeremy in place,” I was told.

Leadership candidates require nominations from 15 per cent of Labour MPs and MEPs, a threshold that the left aims to reduce to just 5 per cent through the “McDonnell amendment” (named after the shadow chancellor, who failed to make ballot when he stood in 2007 and 2010).

Should the rule change pass at this year’s party conference – an unlikely result – the next leadership contest could feature as many as 19 candidates. Labour has no shortage of aspirant leaders: Yvette Cooper, Dan Jarvis, Clive Lewis, Lisa Nandy, Keir Starmer, Emily Thornberry, Chuka Umunna. (Rebecca Long-Bailey, the shadow business secretary and Corbynite choice, is said to believe she is “not ready” for the job.)

All are clear-sighted enough to recognise that Labour’s problems would not end with Corbyn’s departure (nor did they begin with his election as leader). The party must restore its economic credibility, recover in Scotland, or perform far better in England, and bridge the divide between liberal Remainers and conservative Leavers.

Lisa Nandy, one of those who has thought most deeply about Labour’s predicament, told me: “I do think that, for many people, not being able to have time with their families and feel secure about where the next wage packet is coming from, and hope that life is going to get better for their kids, is really pressing as a political priority now. They will vote for the political party that offers real solutions to those things.

“That’s why power is such an important unifying agenda for the Labour Party – not just through redistribution of wealth, which I think we all agree about, but actually the redistribution of power as well: giving people the tools that they need to exert control over the things that matter in their own lives,” she says.

But some Labour MPs suggest even more drastic remedial action is required. “In order to convince the public that you’ve moved on, you have to have a Clause Four-type moment,” one member told me. “Which would probably involve kicking John McDonnell out of the Labour Party or something like that.

“You have a purge. Ken Livingstone gone, maybe even Jeremy [Corbyn] gone. That’s the only way that you can persuade the public that you’re not like that.”

Political commentators often mistake cyclical developments for structural changes. After Labour’s 1992 election defeat it was sometimes said that the party would never govern again. It went on to win three successive terms for the first time in its history. In March 2005 Geoffrey Wheatcroft published his book The Strange Death of Tory England. Less than nine months later, the Conservatives elected David Cameron as leader and returned to winning ways. As the US political journalist Sean Trende has archly observed, if even the Democrats recovered “rather quickly from losing the Civil War” few defeats are unsurvivable.

From despair may spring opportunity. “It is amazing how this Brexit-Trump phase has really mobilised interest in politics,” Nick Clegg said. “It’s galvanised a lot of people . . . That will lead somewhere. If in a democracy there is a lot of energy about, it will find an outlet.”
