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.

Having the last laugh

How Diane Abbott – overlooked, mocked and marginalised by her own party for three decades – ended up as the closest ally of a Labour leader

“I don’t think you’re up to it.” It is 1970, and Diane Julie Abbott, aged 17, is keen to apply to Cambridge University, but her history teacher has other ideas.

“I was an omnivorous reader,” she says now, sitting in her parliamentary office, in a prime spot overlooking the Thames, “and in all these books, particularly these novels between the wars, if you went to university, you went to Oxford or Cambridge.”

The teachers at Harrow County School for Girls, where Abbott was the only black girl in her class, were not supportive. Her memories are less happy than those of her contemporary Michael Portillo, who attended the affiliated boys’ grammar school, and who played Macduff to her Lady Macduff in a school play.

Even when Abbott succeeded, she was regarded with suspicion. She remembers getting an A-minus in an English class – a mark that disappointed her – and being asked to stay behind by the teacher. “She picked up my essay between her thumb and her forefinger and said: ‘Where did you copy this from?’ I was genuinely shocked.”

The story suggests that she acquired her ability to shrug off criticism early. It is also a reminder of how often she is underestimated. The Times journalist Matt Chorley once described a successful day for Labour as one in which “Diane Abbott was on TV a bit less”. Julie Burchill described her in the Spectator as a “preposterous creature” who “blotted the landscape of English politics, speaking power to truth in order to advance her career”. In the Guardian, Michael White dubbed her a “useful idiot”.

She has been endlessly dismissed as stupid, untalented and bad at politics – an obvious “diversity hire”. These criticisms are immune to evidence: her time at Cambridge, the only black British student from a state school in the entire university; her 12 years on the sofa with Portillo on BBC1’s This Week; her time in the shadow cabinet under Ed Miliband; her reliable ability to hold the line in television interviews; and now her status as Jeremy Corbyn’s closest political ally. She is largely ignored by lobby journalists, even as they lament their failure to secure a line into the Labour leader’s thinking. In 2017, Diane Abbott celebrates her 30th year in parliament. Should we take her seriously?

 

****

Abbott’s mother, a nurse, and her father, a welder, were born in the same village in Jamaica, but met and married in London and lived in Notting Hill “before it was a fashionable place to live”. Abbott was born there in 1953, 12 years before the phrase “race relations” first made its way on to the statute books. “My father was very aspirational,” she recalls, “and so every weekend, he and my mother would drive round houses in Pinner, and every Monday they’d ring the estate agent, and the estate agent would say the house had gone. But, of course, the house wasn’t gone.”

Eventually, they did buy a house, not in Pinner but in Edgware, north London. “My brother – his best friend was Jewish,” she tells me, “and he’d attend the Jewish youth club with his friend, and one day his friend said in a really embarrassed way: ‘I’m really sorry, I’m afraid you can’t continue to attend the club, because they’re afraid it will encourage the girls to marry out.’

“The thing was,” she continues, “my brother was upset about this. We were all upset on his behalf but it was just part of life.” And in 1970, a black straight-A student being told that she wasn’t good enough to go to Cambridge was, again, part of life. It was her response that was out of the ordinary: “Well, I do think I’m up to it. And that’s what matters, isn’t it?”

At university, Abbott didn’t get involved in politics, and she found the Cambridge Union off-putting. Her hall tutor advised her to go into the civil service, and so she arrived at the Home Office in 1976, the lone black graduate trainee on what she now describes as “a quixotic quest to do good”.

In turn, that took her to the National Council for Civil Liberties, now Liberty. Believing it to be a hotbed of communist sympathisers, MI5 tapped the office phones, an action that was ruled unlawful in 1990. “One of the things that Diane still talks about,” a friend tells me, “is her experience not only of the Home Office, but of being the subject of official surveillance. She has a cynicism about the state that hasn’t gone away.”

Abbott also joined local campaigns on some of the issues that have defined her career, such as the abolition of the “sus laws”, the informal provision that allowed the police to stop and search anyone under the ­Vagrancy Act, which activists claim was used to target ethnic minorities in Britain. After joining the Labour Party, she became a councillor in Westminster in 1982.

In the 1970s and 1980s, as today, Labour took the lion’s share of the ethnic minority vote. But no one from an ethnic minority had ever sat as a Labour MP. In the 1983 election, just one person from a minority was selected as a parliamentary candidate, and in an ultra-safe Conservative seat. In response, Labour’s minority activists formed the Black Sections, a campaign to secure ethnic minority representation.

It was through these that Abbott met Linda Bellos, who was the leader of Lambeth Council, where Abbott worked as a press officer – her last job before entering parliament. “I was born here in 1950, one of 50,000 black people [living in the UK],” Bellos tells me. “We might have talked about going home but home for me was bleeding London, wasn’t it? Hence the need to make sure we were involved in all of the parts of the state. Someone like Diane had been to Cambridge, she’d been a councillor, she knew the democratic process, she was friends with a number of MPs, she knew the score. If someone like her couldn’t be selected, what was the point of any of us being here?”

The Black Sections wanted affiliated status, similar to that of the Fabians. But there were concerns that black candidates would not appeal to Labour’s presumed core white working-class vote. Some on the left saw “identity politics” as a distraction from the class struggle; and some on the right thought the Black Sections were too radical. At the 1984 conference, their plan was thrown out by a margin of ten to one.

Despite this setback, the fight had an important legacy. In the 1987 elections, four ethnic minority MPs entered the Commons for Labour: Paul Boateng in Brent South, Keith Vaz in Leicester East, Bernie Grant in Tottenham – and, in Hackney North and Stoke Newington, there was the 33-year-old Diane Abbott.

 

****

She was the first black woman to be selected for a safe parliamentary seat. The Times marked the occasion with a leader denouncing her “rhetoric of class struggle and skin-colour consciousness”.

A few months later, the Sun profiled the “ten looniest Labour candidates” in Britain. “We were all there,” Abbott recalls. “Jeremy [Corbyn], the rest of us, and I was number eight.”

The local party in Stoke Newington was delighted with this firebrand reputation. “They said: ‘Stick with us, and we’ll take you right to the top!’”

The voters of north London were less welcoming. A brick was thrown through the office window of her local party. With Abbott as the candidate, some traditional Labour voters switched to the SDP-Liberal Alliance, taking the Labour vote below 50 per cent for the first time in the seat’s history (the second occasion was in 2005, just after the invasion of Iraq).

In parliament, the intake of ethnic minority MPs was regarded with caution. Abbott recalls that the then speaker of the House of Commons, Bernard Weatherill, was “very anxious”. She adds: “He thought we’d be like the Fenians and disrupt and collapse parliamentary process. So he invited Bernie [Grant], who was regarded as our leader, for port. And Bernie came for port and the speaker was very nice to him. And I imagine the speaker thought this was what stopped us being like the Fenians.”

Those Labour MPs who were disruptive – such as Corbyn the serial rebel – were in low spirits for other reasons. The marginalisation of Abbott and her allies during the late 1980s and 1990s explains why they have so little sympathy for the party’s beleaguered centrists in the current power struggle.

At the Labour conference in Liverpool this year – where she spoke as shadow health secretary – Abbott told me: “I came to party conference every year for 20 years, and we would lose and lose and lose. These people have lost twice and they’re complaining!”

Her thick skin was toughened during the New Labour years – and it reaffirmed her close friendship with Corbyn. (The two had a short sexual relationship in the early 1980s, which ended amicably. Abbott was married for two years to a Ghanaian architect from 1991 to 1993; her son, James, was born in 1992.) “She’s always had an odd hold on Jeremy,” one Labour MP tells me. “You would see them having lunch together and her bossing him about. I think people underestimate how influential she
is on his thinking.”

When David Lammy, her neighbouring MP in Tottenham, entered parliament in 2000 following the death of Bernie Grant, he found her “vilified, ostracised and exiled by the Blairites”. There were several attempts to remove her as an MP – another reason why the Corbyn camp is unconcerned by complaints from MPs such as Stella Creasy and Peter Kyle about their local parties threatening to deselect them.

Abbott retains a network of friends from her time before politics, including from her stint as a television producer. They urged her to quit in the Blair years – or to end her association with the left-wing Socialist Campaign Group. “I never thought I was willing to trade what I thought was right for some position in the party,” she says.

Some allies see it differently. “I don’t think Diane is someone who can quit [politics],” a friend told me. “I see her tweeting at all hours. She has interests, books and so forth, but she couldn’t walk away.”

Abbott says that Keith Vaz convinced her to stay, telling her, “You have forgotten what it took for us to get here.” (Some of Corbyn’s allies believe that this is what made the leader so supportive of Vaz during his latest scandal.) This sense of solidarity with other ethnic minority MPs has led to the long-standing rumour that Abbott would have nominated Chuka Umunna had Corbyn not stood for the Labour leadership.

“Diane is absolutely loyal to Jeremy,” one MP who knows them both well tells me. “She’s loyal to the project, yes, but she’s also loyal to him, in a way I don’t think you could honestly say about John McDonnell or Clive Lewis.” During the coup attempt against Corbyn last summer, Abbott spoke forcefully in favour of Corbyn remaining in place, rather than striking a deal to put Lewis or McDonnell on the ballot. “Her position,” one insider recalls, “was that we’d got a candidate we knew could win, and that candidate was Jeremy.”

Not that they always agree. Abbott advocated a less conciliatory approach after Corbyn’s first victory in 2015. “The thing that can be infuriating about Jeremy is that he likes to think the best of everyone,” she says. “I’m always perfectly straight with him as to what I think, and even if he doesn’t believe me at the time, he always does come round to my point of view.”

Abbott is one of the few people in the Parliamentary Labour Party whom Corbyn trusts completely. In their relationship, it’s hard to see who is the senior partner.

In the late 1990s and early 2000s, Corbyn and Abbott settled into a pattern of dissent, followed by defeat. Corbyn spent the time attending to foreign and human rights campaigns and signing thousands of early day motions. Abbott carved out a niche as a reliable critic of the Labour government under Tony Blair, with a month-long slot at the launch of the BBC’s This Week in 2003 blossoming into a regular gig alongside Michael Portillo. But away from Westminster, Abbott was making a decision that she knew could destroy her political career.

 

****

The London borough of Hackney is today a national leader in schooling, but in 2002, just a third of students received five or more A*-C grades. That prompted Abbott to send her ten-year-old son, James, to City of London, a leading private school.

“I knew I could lose the seat over it,” she told me. “I was a single parent, and time after time, I had not been there for things at school, or I was too tired to take him out somewhere . . . I just thought, just this once, I should be prepared to make a sacrifice for him. If I lost the seat, then I lost the seat.”

She kept the seat. “Other things do annoy Diane – reporters saying things about her that aren’t true, people talking down to her,” one friend tells me. “But with [the schooling] I think she was very happy with that deal and to take that blow.”

Then, in 2010, Abbott’s career began a surprising second act: a bid for the party leadership. Activists and commentators felt uninspired by the choice in front of them – Ed Miliband, David Miliband, Andy Burnham and Ed Balls, four former special advisers from the New Labour era. Abbott called them “geeky men in suits”. Harriet Harman, in particular, was keen that the contest should not be an all-male field. Her support swayed Abbott. “If you had to pick one person, it was her,” she says, “because she was more mainstream.”

David Lammy set up a meeting between Abbott and David Miliband. The front-runner told her that, if she were a vote short in the nominations from MPs, he would vote for her. “But because it was David Miliband, I didn’t believe him.”

The elder Miliband had his own reasons for backing her. He believed that having her on the ballot would deprive his brother, Ed, of valuable support from the left. This was also the calculation that allies of Yvette Cooper made about Corbyn in 2015. “David’s legacy,” the Wakefield MP, Mary Creagh, wrote five years later, “made it normal – Blairite, even – to put a left-winger on the ballot to ‘have a broad debate’.’’

Of Corbyn’s campaign, Abbott says now: “I knew he’d do well, because what people missed is that had it been one person, one vote [in 2010], I’d have come third.”

Had the unions and the MPs not had a disproportionate influence on the result, she says, “I’d have beaten Andy Burnham, I’d have beaten Ed Balls. I’d been to 53 hustings – most Labour people are where Jeremy and I were. I knew there was much more left-wing sentiment in the Labour Party than the lobby thought.”

As a result of Corbyn’s victory in 2015, she is shadowing one of the great offices of state in what once looked like her final term in parliament. Her policy priorities as shadow home secretary are broad but include her favoured subjects of police reform and anti-racism. “I want to help shape the debate on migration,” she tells me. “I think we’ve had a very vacuous debate.”

That has put her at odds with the shadow chancellor, John McDonnell. Though both are long-time friends of Corbyn, their relationship is not warm. Allies believe that the division stretches back to the late 1980s, when McDonnell – then outside parliament – gloried in not going “soft” in the manner of Neil Kinnock. Abbott attracted suspicion, in part because of her early conversion to a pro-European position. Many believe that McDonnell never embraced the European project. He has ruled out opposition to Brexit and is behind the toughening of the party’s line on immigration. Abbott, privately and publicly, is determined to hold Labour to a more open and pro-immigration position. She has said that Labour cannot win as “Ukip-lite”, a coded rebuke to McDonnell.

The shadow chancellor is the only MP with a comparable influence to Abbott’s on Jeremy Corbyn and, thus far, the Labour leader has struck a middle path on migration, supporting Abbott’s line that the single market cannot be traded away for restrictions on the free movement of people but stopping short of a full-throated defence of free movement in principle.

As well as winning that internal battle, Abbott faces the task of landing more blows on Amber Rudd than her predecessors – Andy Burnham, Yvette Cooper and Ed Balls – managed against Theresa May when she was the longest-serving home secretary in a century, transforming the reputation of a department once regarded as a political graveyard. Not many give Abbott much chance of success but, as always, she believes in herself and thinks that she’s up to it.
