Drastic and immediate cuts in carbon emissions, as advocated by most of the green lobby, are an expe

There is a disturbing tendency among many in the climate debate today to deride as "deniers" anyone who does not advocate making huge and immediate carbon cuts. The framing began nearly a decade ago with discussions about the science of climate change. People who questioned the link between carbon emissions and warming were branded "deniers".

The semantic similarity to Holocaust denial was made overt when several prominent environmental campaigners suggested a need for Nuremberg-style trials for their opponents. Such rhetoric was deeply unfortunate. However, one could at least argue that the resulting fiery debate achieved one positive thing: it played a role in rousing most climate scientists to join together to underscore the message that global warming is largely man-made.

We have long since moved on from any mainstream disagreements about the science of global warming. Now, the crucial conversation is about the economics of our response. Today, the labels "denier" and "sceptic" are hurled at anyone who does not fervently argue for drastic, immediate carbon cuts. There is no possible justification, given that so many climate economists - the specialists in this field - recommend very different policies from those being advocated by the zealous carbon cut lobbyists.

In my book, first published in Danish in 1998, and then in English as The Skeptical Environmentalist in 2001, I wrote that man-made global warming exists. I could not have been clearer; the introduction to the section on climate change states: "This chapter accepts the reality of man-made global warming." My position has not changed. Thus, when I am labelled a "long-time climate sceptic" or "climate change denier" by
bloggers and activists, it is not based on any suggestion I have ever declared that the science of global warming is wrong. Rather, it is the campaigners' heated response to my pointing out that drastic carbon cuts don't make sense and that smarter policy responses should be considered.

It is understandable that emotions run high in such a defining discussion. I can appreciate, even in those who disagree with me, a moral intent to do good for humanity. But I cannot see how responding to empirical economics with slander will ever be helpful. Much worse than that, I believe that ignoring - or, indeed, denying - basic economic reality is a shoddy way of helping the planet.

In July, the G8 agreed to make carbon emission cuts to limit global warming to no more than 2°C above pre-industrial levels. This would be the most costly public policy humanity has ever enacted.

The Copenhagen Consensus Centre recently asked top climate economists to explore the benefits and costs of different responses to global warming, to prompt a discussion about the solutions that would have the biggest impact on climate for the lowest cost. We convened a second stellar group of top economists, including three Nobel laureates, to examine independently all of the research and rank the proposals in order of desirability.

One research author, the prominent climate economist Professor Richard Tol, who has been a contributing, lead, principal and convening author for the IPCC, strikingly showed that grand promises of drastic, immediate carbon cuts are a hugely expensive way of doing very little good. Reducing emissions by 80 per cent by mid-century (to achieve the 2°C goal) would avert much of the expected damage of global warming; based on conventional estimates, it would avoid climate damages of about £1.9trn a year by 2100. However, the cost of this would be a reduction in growth - particularly damaging to the world's poor - to the tune of around £25trn a year. Moreover, the costs would come much sooner than the benefits. Every pound spent on this grand plan would achieve twopence worth of good.

Put starkly: drastic carbon cuts would hurt much more than climate change. Cutting carbon is extremely expensive, especially in the short term, because the alternatives to fossil fuels are few and costly. Without feasible alternatives, we just hurt growth, which would be especially damaging for countries such as Brazil, China and India, dependent on fossil fuels to lift millions out of poverty.

It is important to emphasise that Tol's figures are based on projections from all the major economic energy models of the Stanford Energy Modelling Forum. Around half of the models found it impossible to achieve the target of keeping temperature rises lower than 2°C with carbon cuts. The £25trn price tag is optimistic because it comes only from the models that project the target is even possible.

The cost assumes that politicians everywhere in the world would, throughout the entire century, make the most effective, efficient choices possible to reduce carbon emissions. Dump that far-fetched assumption and the cost could be ten or even 100 times higher.

The Copenhagen Consensus on Climate's expert panel considered Tol's research - along with other proposals for responses to global warming - and concluded that drastic carbon cuts would be the poorest approach. The economic lessons are underpinned by real-world experience. In Rio de Janeiro in 1992, politicians from wealthy countries promised to cut emissions by 2000, but did no such thing. In Kyoto in 1997, leaders promised even stricter reductions by 2010, yet emissions have kept increasing unabated. It is little wonder that politicians are backing away from promising that they will be able to broker a new deal on carbon cuts in Copenhagen this December.

Despite the shambles of the Copenhagen negotiations, many carbon cut campaigners refuse to discuss alternative approaches. By dismissing critics as "deniers" and "sceptics", they commit the planet to the poorest policy choice - and one with very little chance of succeeding in controlling temperature rises. We could and should do better. The expert panel of Nobel laureate economists, working for the Copenhagen Consensus on Climate, revealed smarter solutions.

The panel recommended immediate research into climate engineering technology and a substantial increase in research and development of green energy alternatives. The two approaches complement each other. Climate engineering has the advantage of speed. There is a significant delay between carbon cuts and any temperature drop - even halving global emissions by mid-century would barely be measurable by the end of the century. And making green energy cheap and prevalent will also take a long time. After all, electrification of the global economy is still incomplete after more than a century of effort.

Climate engineering has a lot of potential as a way for us to buy more time - but it does not appear to be a long-term answer. We could gain time to ensure that we can shift sustainably and efficiently away from reliance on fossil fuels, which requires the investment in researching alternatives to these fuels.

Many of us fear climate engineering. But the groundbreaking research paper by Eric Bickel and Lee Lane at the University of Texas - one of the first studies of the costs and benefits of these technologies - offers compelling evidence that a tiny investment in climate engineering might be able to reduce as much of global warming's effects as trillions of pounds spent on carbon emission reductions.

The most attractive technology Bickel and Lane examine appears to be marine cloud whitening, where boats spray seawater drop-lets into clouds at sea to make them whiter and thus reflect more sunlight back into space, so reducing warming. This augments the natural process whereby sea salt from the ocean is whipped up and provides cloud condensation nuclei. Marine cloud whitening would not lead to permanent atmospheric changes, and could be used only when needed.

The researchers conclude, remarkably, that we might be able to cancel out this century's entire global warming with 1,900 unmanned ships spraying seawater mist into the air, at a total cost of about £6bn. When the benefits from averted warming are calculated, this is the equivalent of doing more than £2,000 worth of good with every pound spent.

President Barack Obama's science adviser, John Holdren, has said that climate engineering has "got to be looked at", and many prominent scientists agree. Concerns about the ramifications of this technology are a reason to research now to identify all of the limitations and risks. If it turns out that this is not a feasible or sensible approach, we need to have that information as soon as possible.

Marine cloud whitening would obviously not solve every aspect of global warming. But it would achieve more, much faster, than any plausible carbon cuts could ever do, and at a fraction of the price. If we are concerned with solving global warming, then we have a moral obligation to research what we could achieve with this technology.

But there is no point in using climate engineering to buy more time if we do not use it effectively. Since politicians started negotiating carbon agreements, we have wasted nearly 20 years without making any significant progress in reducing global warming. Focusing primarily on how much carbon to try to cut through taxes, rather than on how to achieve this technologically, puts the cart before the horse.

Global energy demand will double by 2050, according to research by the respected climate change economists Chris Green and Isabel Galiana from McGill University in Montreal. Use of fossil fuels remains vital for our development, prosperity and survival. Alternative sources of energy are unfortunately far from ready for widespread use. Green and Galiana show that, to reduce carbon emissions by three-quarters by 2100 while maintaining reasonable growth (a less ambitious goal than the G8's), non-fossil-fuel-based sources of energy will have to be an astonishing two and a half times greater in 2100 than the total level of global energy consumption in 2000.

If we continue on our current path, technological development will not be anywhere near significant enough to make non-carbon-based energy sources competitive with fossil fuels on price and effectiveness. Green and Galiana examine the state of non-carbon-based energy today - nuclear, wind, solar, geothermal, etc - and find that, taken together, alternative energy sources would get us less than halfway towards a path of stable carbon emissions by 2050, and only a tiny fraction of the way towards stabilisation by 2100. The technology will not be ready in terms of scalability or stability. In many cases, there is still a need for the most basic research and development. We are not even close to getting this revolution started.

Current technology is so inefficient that we would have to blanket most countries with wind turbines to power everybody's needs, and even then we would have the problem of storage when the wind doesn't blow.

Many environmental campaigners lauded China's ambition to create "green cities", powered by huge wind farms. But China plans to build dozens of new coal-fired power plants for these cities, too: otherwise, there will be blackouts every time there is not enough wind. The vast majority of Chinese cities will still rely on electricity from coal.

If governments try to cut carbon through taxes and trading schemes without effective replacements, we will make virtually no difference to climate change in the future, while in the shorter term there will be significant damage to economic growth.

Public funds on research and development also need to increase dramatically. We cannot rely on private enterprise alone. As with medical research, early innovations will not reap significant financial rewards, so there is no strong incentive for private investment today. While many of us assume that green research and development must have increased dramatically over the past decade, the actual numbers from the International Energy Agency show that not only has this spending not risen, but it has actually declined significantly since the early 1980s.

Policymakers should abandon fraught carbon reduction negotiations and instead make agreements to invest in research and development to get this technology to the level it needs to be. Provided that this spending doesn't go into subsidising existing, inefficient technology, but is instead put towards promoting innovation, this would have a far greater chance of tackling climate change - and a far greater chance of political success.

The biggest carbon emitters of the 21st century, including India and China, are understandably unwilling to sign up to tough, costly emission targets. They would be much more likely to embrace a cheaper, smarter and more beneficial path of innovation. Ultimately, we will not succeed politically or economically in tackling climate change by making fossil fuels so expensive that nobody will use them. However, if we forge onwards with dramatically increased research and development, towards the middle of the century we could make green energy so cheap that everyone will use it.

Discussions about solving the planet's problems will always be emotional. But they should also be reasoned. The most reasonable response to global warming is to change our course and focus on an approach that would actually work.

Divided Britain: how the EU referendum exposed Britain’s new culture war

The EU referendum exposed a gaping fault line in our society – and it’s not between left and right.

There are streets in Hampstead, the wealthy northern suburb of London, where the pro-EU posters outnumber cars. A red “Vote Remain” in one. A “Green Yes” in another. The red, white and blue flag of the official campaign sits happily next to a poster from the left-wing campaign Another Europe Is Possible proclaiming that the world already has too many borders.

If you were looking for an equivalent street in Hull, in the north of England, you would look for a long time. In the city centre when I visited one recent morning, the only outward evidence that there was a referendum going on was the special edition of Wetherspoon News plastered on the walls of the William Wilberforce pub in Trinity Wharf. Most of the customers agreed with the message from the chain’s founder, Tim Martin: Britain was better off outside the European Union.

“Far too much Hampstead and not enough Hull” – that was the accusation levelled at the Remain campaign by Andy Burnham in the final weeks of the campaign. He wasn’t talking about geography; Remain’s voice is persuasive to residents of Newland Avenue in Hull, where I drank a latte as I eavesdropped on a couple who were fretting that “racists” would vote to take Britain out of the EU.

Rather, Burnham was talking about an idea, the “Hampstead” that occupies a special place in right-wing demonology as a haven of wealthy liberals who have the temerity to vote in the interests of the poor. The playwright and novelist Michael Frayn, in his 1963 essay on the Festival of Britain, called them “the Herbivores”:

“. . . the radical middle classes, the do-gooders; the readers of the News Chronicle, the Guardian, and the Observer; the signers of petitions; the backbone of the BBC . . . who look out from the lush pastures which are their natural station in life with eyes full of sorrow for less fortunate creatures, guiltily conscious of their advantages, though not usually ceasing to eat the grass.”

For Hampstead then, read swaths of Islington, Hackney, Brighton, Bristol, Cambridge, Edinburgh and Oxford today – all areas that were most strongly in favour of Remain and where Jeremy Corbyn is popular. But Remain never found a tone that won over the other half of Labour England; the campaign struck as duff a note among the diminishing band of pensioners on Hampstead’s remaining council estates as it did on Hull’s Orchard Park Estate.

The rift between “Hampstead and Hull”, in the sense that Andy Burnham meant it, is one that has stealthily divided Britain for years, but it has been brought into sharp focus by the debate over Europe.

Academics use various kinds of shorthand for it: the beer drinkers v the wine drinkers, or the cosmopolitans v the “left behind”. “It’s not just that [Britain] is div­ided between people who buy organic and people who buy own-brand,” says Philip Cowley, a professor of politics at Queen Mary University of London, “but between people who wouldn’t understand how anyone could buy own-brand and people who wouldn’t buy organic if you put a gun to their head.” Equating political preferences with shopping habits might sound flippant, but on 21 June the retail research company Verdict estimated that “half of Waitrose shoppers backed a Remain vote, against just over a third of Morrisons customers”.

The referendum has shown that there is another chasm in British politics, beyond left and right, beyond social conservatism v liberalism, and beyond arguments about the size of the state. The new culture war is about class, and income, and education, but also about culture, race, nationalism and optimism about the future (or lack of it). This divide explains why Ukip’s message has been seductive to former Labour voters and to Tories, and why Boris Johnson, an Old Etonian, led a campaign that purported to despise “elites” and “experts” and spoke of “wanting our country back”.

***

At the start of the campaign, the question that most accurately predicted whether you would back Remain or Leave was consistently: “Are you a graduate?” (Those who answered yes were much more likely to vote in favour of staying in the EU.) Stronger In never found a way to change that and win over those who left education at 18 or earlier. Pollsters also suggested that the much-vaunted Euroscepticism of older voters reflects generations where only one in ten people went to university.

This fissure has been growing for the best part of a decade and a half, but Britain’s first-past-the-post system, which deters newcomers and maintains entrenched parties, has provided a degree of insulation to Labour that its European cousins have lacked. Yet even here in the UK the mid-Noughties brought the brief rise of the British National Party, powered by voter defections from Labour in its strongholds in east London and Yorkshire, as well as the election of the Greens’ first MP on the back of progressive disillusionment with the governments of Tony Blair and Gordon Brown.

In office, both Blair and Brown calculated, wrongly, that Labour’s core vote had “nowhere else to go”. In opposition under Ed Miliband, the party calculated, again wrongly, that discontent with immigration, and the rise of Ukip powered by that discontent, was a problem for the Conservative Party alone.

In a 2014 pamphlet for the Fabian Society, ­Revolt on the Left, the activist Marcus Roberts, the academic Rob Ford and the analyst Ian Warren warned that Labour had “few reasons to cheer about the Ukip insurgency and plenty to worry about”. When the votes were cast in the general election the following year, that prediction turned out to be dispiritingly accurate. Defections from Labour to Ukip led to Labour losing seats to the Conservatives in Gower, Southampton Itchen, Telford and Plymouth Moor View.

For the most part, however, first-past-the-post papered over the cracks in Labour’s broad coalition: cracks that, in the harsh light of the EU referendum, have become obvious. The divide isn’t simply one of class, or income. The social profile and culture of voters in Cumbria are no different from that of voters on the other side of the border – but Scots in the Borders backed a Remain vote while their English peers in the border areas opted for Brexit. Inhospitality towards Brexit proved a stronger indication of city status than a mere cathedral: Vote Leave generally found Britain’s great cities more difficult terrain than the surrounding towns and countryside.

The problem of the fracturing vote is particularly acute for the Labour Party, which for much of the 20th century was able to rely on the Herbivores. In concert with Frayn’s “less fortunate creatures”, they have been enough to guarantee Labour close to 250 seats in the House of Commons and roughly one-third of the popular vote, even in difficult years. But Britain’s EU referendum placed Hampstead and Hull on opposing sides for the first time in modern British political history.

It was Tony Blair who, in his final speech to the Trades Union Congress as Labour leader in September 2006, said that the new debate in politics was not left against right, but “open v closed” – openness to immigration, to diversity, to the idea of Europe. Driven by their commitment to openness, Blair’s outriders dreamed of reshaping Labour as a mirror of the US Democrats – though, ironically, it was Ed Miliband, who repudiated much of Blair’s approach and politics, who achieved this.

At the 2015 election Labour’s coalition was drawn from the young, ethnic minorities and the well educated: the groups that powered Barack Obama’s two election wins in 2008 and 2012. The party was repudiated in the Midlands, went backwards in Wales and was all but wiped out in the east of England. (Scotland was another matter altogether.) Its best results came in Britain’s big cities and university towns.

The Remain campaign gave Labour a glimpse of how Miliband’s manifesto might have fared without the reassuring imprimatur of a red rosette. Britain Stronger In Europe has been rejected in the Midlands and struggled in the east of England. But it also failed to inspire passion in Sunderland, Oldham and Hull – all areas that, for now, return Labour MPs.

***

In appearance, Hull’s city centre is built on blood and sandstone, dotted with memorials to a lost empire and postwar replacements for bombed buildings, all ringed by suburban housing built by the private sector in the 1930s and the state in the 1950s and 1960s. It could be Bristol without the excessive hills, or a smaller Glasgow with a different accent. Unlike in Glasgow or Bristol, however, the residents of Hull are largely hostile to the European Union. Unlike Glasgow and Bristol, Hull is a post-imperial city that has yet to experience a post-colonial second act.

The William Wilberforce is named after a native son who helped destroy the British slave trade, the engine of Hull’s prosperity in the 18th century. The destruction of another local industry – fishing – drives resentment among the pub’s ageing clientele, who were there for breakfast and a bit of company when I visited. They blame its demise squarely on the EU.

Although the Labour Party now has only one MP in Scotland, the back rooms of the labour movement host an outsized Scottish contingent. For that reason – and the continuing threat that the loss of Labour’s seats in Scotland poses to the party’s chances of winning a majority at Westminster – the Scottish independence referendum of 2014 loomed large for Labour throughout the EU campaign.

From the outset, Britain Stronger In struggled to replicate the success of the Scottish No campaign, in part because the price of victory was one that Labour regarded as too high to pay a second time. In Glasgow, in the week before the Scottish referendum, everyone knew where Labour stood on independence – consequently, many voters were already planning to take revenge. The proprietor of one café told me that Labour was “finished in this city, for ever”.

Predictions of this sort were thin on the ground in Hull. Alan Johnson, the head of Labour’s EU campaign, is one of the three Labour MPs whom Hull sent to Westminster in 2015. But even late in the campaign, in his own constituency, I found uncertainty about the party’s official position on the referendum. For that reason, if nothing else, it didn’t have the feeling of a city preparing to break with a half-century-plus of Labour rule, as Glasgow did in 2014. In Scotland, most people I spoke to believed that they were on the brink of independence, which made the eventual result a big blow.

Only among Hull’s pro-European minority could I find any conviction that Britain might actually leave the EU. In September 2014 Kenneth Clarke remarked that Ukip’s supporters were “largely . . . the disappointed elderly, the grumpy old men, people who’ve had a bit of a hard time in life”. To listen to Hull’s Leave voters is to hear tales of the same frustrated potential: they feel that politicians of all stripes have lives entirely removed from theirs. In their defence, they are right – just 4 per cent of MPs in 2010 were from working-class backgrounds.

As for Ken Clarke, he has carved out a second career as every left-winger’s favourite Tory, but that tone of indifference towards the “disappointed lives” of globalisation’s casualties recalls his younger days as a rising star of Margaret Thatcher’s government.

Hull’s residents have been dismissed, first as the regrettable but inevitable consequence of Thatcherite economics, and now as small-minded opponents of social progress and racial diversity. Unsurprisingly, people who feel that their wishes have been ignored and in some cases actively squashed by successive governments of left and right did not expect to wake up on the morning of 24 June to discover that this time, their votes really had changed something.

Equally unsurprisingly, the Remain campaign’s warnings of economic collapse lacked force for people for whom the world’s end had been and gone.

In Glasgow in 2014 Scottish independence was a question of identity in itself, whereas in Hull, hostility towards Europe is the by-product of other identities that feel beleaguered or under threat: fishing, Englishness and whiteness, for the most part.

In Hampstead, a vote for Remain feels more like a statement about the world as you see it. One woman, who walks off before I can probe further, tells me: “Of course I’m voting to stay In. I buy Fairtrade.”

***

Immigration, not the European Union, is the issue that moves voters in Hull. “Britain is full” was the most frequent explanation they gave for an Out vote. Knowing that immigration, rather than the abstract question of sovereignty, would be crucial to winning the contest, Vote Leave tried from the beginning to make it a referendum on border control. Leave’s main theme: the threat of Turkey joining the European Union and, with it, the prospect of all 75 million Turks gaining the right to live and work in Britain.

Although Turkey’s chances of joining the EU are somewhere only just north of its hopes of launching a manned mission to Mars, the tactic worked: according to an ­Ipsos MORI poll released on the morning of 16 June, 45 per cent of Britons believed that Turkey will be fast-tracked into the Union.

That same morning, Nigel Farage posed in front of a poster showing refugees – mostly from Syria and most of them non-white – on the border between Croatia and Slovenia, with a slogan warning that uncontrolled immigration was leaving Britain at “breaking point”. But the row over the poster came to an unpleasant halt just a few hours later as news began to break that Jo Cox, the Labour MP for Batley and Spen, had been shot and stabbed on her way out of a constituency surgery. She died of her injuries a little over an hour later. On 19 June Thomas Mair, who was arrested in connection with the killing, gave his name at Westminster Magistrates’ Court as “Death to traitors, freedom for Britain”.

The circumstances of the killing felt familiar. A little after midnight on 5 June 1968, Robert Kennedy was returning to the Ambassador Hotel in Los Angeles in high spirits. He had just won a crucial victory in the California primary and was well placed to secure the Democratic nomination to run in that year’s presidential election. Going through the kitchen in order to avoid cheering crowds and get straight to his press conference, he was ambushed by a man called Sirhan Sirhan, who fired six shots from a revolver. Kennedy was rushed to hospital, where he died early the following morning.

Five months later Richard Nixon was elected president. The American right held on to the White House for 20 years out of the next 25. Jo Cox’s killing, amid the nativist howling from Farage et al, felt like the beginning of a similar chapter of right-wing advance in the UK.

Labour’s problem, and that of its social-democratic cousins throughout Europe, is the same as the American left’s was in the 1960s. Its founding coalition – of trade unions, the socially concerned middle classes and minorities, ethnic and cultural – is united (barely) on economic issues but irrevocably split on questions of identity. Outside crisis-stricken Greece and Spain, the left looks trapped in permanent opposition, with no politician able to reconsolidate its old base and take power again.

***

When I arrive in Hull, preparations are under way for a vigil in Jo Cox’s honour, but it is the nation of Turkey that is weighing on the minds of undecided voters. On Park Street, residents are divided. Those who have exercised their right to buy and are concerned about their mortgages are flirting with an Out vote but are terrified about negative equity. Those who remain in social housing or the private rented sector are untouched by stories of soaring mortgages. To many residents, the Treasury’s dire warnings seem to be the concerns of people from a different planet, not merely another part of the country. As Rachel, a woman in her mid-fifties who lives alone, puts it: “They say I’d lose four grand a month. I don’t know who they think is earning four grand a month but it certainly isn’t me.”

As Vote Leave knew, the promise that an Out vote will allow people to “take control” always had a particular appeal for those with precious little control – of their rent, of next week’s shift, of whether or not they will be able to afford to turn the heating on next week. Never mind that the control envisaged by Vote Leave would be exercised by the conservative right: the campaign found a message that was able to resonate across class and region, at least to an extent that could yet create a force to be reckoned with under first-past-the-post in Britain.

Four grand a month isn’t a bad salary, even in leafy Hampstead, but in that prosperous corner of north London fears of an Out vote, and what will come after, gained a tight purchase. The worry was coupled with resentment, too, over what would come, should the Outers triumph.

The great risk for the left is that herbivorous resentment is already curdling into contempt towards the people of Hull and the other bastions of Brexitism. That contempt threatens the commodity on which Labour has always relied to get Hull and Hampstead to vote and work together – solidarity. The referendum leaves the Conservatives divided at Westminster. That will give little comfort to Labour if the long-term outcome of the vote is to leave its own ranks divided outside it.
