Boris Johnson's climate change "scepticism" is an embarrassment to London's scientists

The Mayor's suggestion that we are heading for a "mini Ice Age"shows that he does not understand the basic science behind global warming.

Boris Johnson has become a real embarrassment to London's scientific community after his latest outburst of climate change ‘scepticism’, which exposes not just a glaring weakness in his own knowledge but also within his team of advisers.

On Monday, Johnson used his Telegraph column to muse on the global climatic implications of a few days of wintry weather in the UK in January. He concluded that it might be time for policy-makers to consider whether the earth is heading for a "mini Ice Age".

This is complete rubbish, of course, and shows not only that Johnson does not understand the basic science behind global warming but also that he cannot distinguish between anecdote and evidence, or between weather and climate.

Claiming to be "an empiricist", Johnson suggested that this is "the fifth year in a row that we have had an unusual amount of snow" and that "I don’t remember winters like this". Unfortunately, his commitment to observational analysis apparently does not extend to consulting the Met Office’s records, which would have shown him that although the average temperatures in the UK during winters 2008-09, 2009-10 and 2010-11 were below average, last winter was actually warmer than average, as were most winters since 2000.

Furthermore, he would have discovered that the UK’s climate bears the unmistakeable footprint of global warming, with the seven warmest years on record all occurring since 2000. So why does the Mayor claim we are experiencing global cooling?

Well, it seems that the only person Johnson consults on this issue is his friend Piers Corbyn, who rejects the overwhelming evidence that rising atmospheric levels of greenhouse gases is driving the unambiguous rise in global average temperatures, and instead holds the sun directly responsible for trends in the Earth’s climate.

The trouble with Dr Corbyn’s theory, which he has not published in any peer-reviewed scientific journal, is that it is not supported by evidence. He does not even believe that the earth’s climate is controlled by the amount of energy radiated from the sun, but instead blames its magnetic activity, which increases and decreases cyclically about every 11 years and so clearly cannot be the main driver of global warming.

Johnson’s description of Dr Corbyn’s theory is an almost verbatim reproduction from one of his earlier columns last July (clearly the £250,000 he is allegedly paid each year is not high enough to guarantee original content for its readers), and is punctuated with references to JMW Turner, Shakespeare and the Aztecs, but largely devoid of scientific insight.

This latest gaffe follows his decision last year to invite Matt Ridley, a prominent climate change ‘sceptic’ and former chairman of Northern Rock, to speak at City Hall about how environmental risks are overblown, as part of the cultural celebration that accompanied the Olympics.

Perhaps we should not be surprised by all this given the complete lack of scientific education that Johnson has received. However, the Mayor has to take scientific evidence and expert knowledge into account when making many important decisions, not the least of which is how to adapt the capital’s transport system and infrastructure to withstand the impacts of global warming. He should not be relying on the fanciful theories of friends when it comes to issues that affect the lives and livelihoods of Londoners.

Johnson should make better use of the fact that the capital is home to many world class universities and scientific societies where he could consult genuine experts, most of whom now cringe every time he holds forth about climate change. But it is also time that the Mayor of London followed the example of central government departments by adding a professional and credible chief scientific adviser to his team.

Do you see yourself as British or English? The answer could help define modern politics

The rise of English identity has left a glaring space in politics for an English nationalist party. Who is going to fill it?

Political scientists call it the “Moreno question”. In the 1980s, the Spanish academic Luis Moreno Fernández came up with a test for identity, which was originally applied to gauge interest in Catalan independence. In its English incarnation, it asks voters to grade themselves from “I feel more British than English” to “I feel more English than British”. Unsurprisingly, Ukip does best among those who describe themselves as “English, not British”, while Labour’s vote rises the more people see themselves as British. In the biggest group – the 47 per cent who see themselves as equally English and British – the Tories lead.

The Moreno question helps us make sense of three interlinking trends in modern politics. First, the stark fact that in the 2015 election, a different party won in each nation of the United Kingdom: Labour in Wales, the SNP in Scotland, the Tories in England and the Democratic Unionist Party in Northern Ireland. Second, Ukip’s lack of success north of the border: the Herald reported in July that Ukip’s only elected representative in the country, David Coburn MEP, had been forced to take on the role of treasurer at his local branch in Fife because it has so few members. Third, Labour’s declining performance in its historic northern heartlands. Many voters there want a party with a distinctively English flavour and don’t feel that Labour is it.

Devolution has had many unexpected consequences, but the rise of an English identity is one of the least explored. Because of its demographic dominance, mainstream politicians have long argued that it would be unfair to give England its own parliament. Labour is particularly resistant to the idea because it would magnify the Conservatives’ power. As it is, the principle of “English votes for English laws” will exclude the SNP and Plaid Cymru from the grand committee-stage hearings on grammar schools, because education is a devolved matter.

However, the last general election showed that there’s a problem with English voters feeling ignored. In Worcester, the Tory MP Robin Walker told me in April 2015 that arguments about the SNP holding Labour to ransom cut through on the doorstep. “There is a real concern if [voters] are saying, ‘The proceeds of the mansion tax are all going to go on nurses in Scotland. That doesn’t help us,’” he said. Many English voters felt that the SNP would be a successful lobby group at Westminster for Scotland’s interests. Where was their equivalent?

For John Denham, the former Labour MP who now leads the Centre for English Identity and Politics at the University of Winchester, the same dynamic applied this summer in the EU referendum campaign. “Scotland got ‘Scotland Stronger in Europe’,” he tells me. “England had to put up with ‘Britain Stronger in Europe’. That was an elite campaign run by people who think Britain and England are the same thing.”

Once again, the Moreno question helps us understand a fundamental divide among English voters. Denham says that 80 per cent of people who defined themselves as “English only” voted Leave, while 80 per cent of those who called themselves “British only” voted Remain.

Denham thinks that this presents an enormous challenge for Labour in northern seats where Ukip is in second place, given that its intellectuals and leading politicians feel so squeamish about Englishness. “If Labour continues as a cosmopolitan, liberal party that doesn’t want anything to do with the politics of identity,” he warns, “it won’t reach those voters.”

Other politicians worry that if Labour doesn’t occupy this space, another party will. “As nationalists go, the SNP is pretty good,” a senior left-wing politician told me recently. “An English nationalist party could be something altogether more nasty.”

In this light, the election of Diane James as the leader of Ukip looks like a rare stroke of luck for Labour. She is a southerner, educated at Rochester Grammar School, and an MEP for south-east England. Although she is polished and professional – albeit prone to outbursts of admiration for Vladimir Putin – she seems unlikely to appeal on an emotional level to working-class white voters in the north, where the greatest potential for an English nationalist party lies. Thanks to Ukip’s Caligulan internal politics, the deputy leader, Paul Nuttall (from Bootle), did not stand and the charismatic Steven Woolfe (from Burnage) was excluded from the race after the party’s executive committee ruled that he had submitted his nomination papers 17 minutes after the deadline. (Another potential candidate, Suzanne Evans, was suspended by the party, and pretty much everyone else in Ukip seems to hate its only MP, Douglas Carswell.)

If not Labour, or Ukip, perhaps the Conservatives? Theresa May’s rebranding of the party, complete with articles on bringing back grammar schools in the Daily Mail, shows that she is pitching for Ukip-leaners. “In terms of language and biography, she has a better understanding of that struggling, socially conservative, English nationalist voter than Cameron did,” says Robert Ford, a professor of political science at Manchester University and co-author of Revolt on the Right. He believes that any party that thinks a simple economic message can sway these voters is underestimating the “emotive” nature of identity-based politics. “It’s no use going to Sunderland and saying, ‘We’re going to nationalise the trains,’ and thinking, ‘They’ll come back to us.’”

There is another option. A new party could be born, perhaps even out of the ashes of post-referendum Ukip: Arron Banks, its mega-donor, has said that he fancies the idea. With the right leader, nationalist sentiment could spread like wildfire among the “English, not British”. And, as Nigel Farage has shown, you don’t need to get elected to Westminster to have an effect.
