Why can't we do anything about the weather?

It’s hard to fathom that the warmth you feel (or don’t feel) today was created at a time when Neanderthals were still around. Yet that is not the real mystery. . .

We’re all still reeling from the Met Office’s warning that we may be facing a decade of miserable summers. Perhaps it will help to recall that we don’t know everything about the sun. That burning ball of gas in the sky remains something of a mystery, and not just for its refusal to shine with any consistency over the UK.
 
The centre of the sun is fairly straightforward. Atoms of hydrogen fuse, forming atoms of helium and releasing energy that powers more fusion. That ongoing chain reaction, burning several million tonnes of hydrogen per second, heats the core of the sun to temperatures of roughly 15m°.
 
The laws of thermodynamics tell us that energy moves from hot to cold, and so heat starts moving towards the surface of the sun, where the temperature is a balmy 6,000°. It’s not an easy journey, though. It’s only about 700,000 kilometres, or a trip from the earth to the moon and back, but it takes the packets of energy released in nuclear fusion something like 40,000 years to reach the sun’s surface.
 
It’s hard to fathom that the warmth you feel (or don’t feel) today was created at a time when Neanderthals were still around. Yet that is not the real mystery. The problem that has scientists scratching their heads is the temperature of the outer layer of the sun’s atmosphere, the corona. The temperature of this blanket of ionised gas is roughly 1m° to 2m°. Bafflingly, the further away you move from the furnace at the centre of the sun, the hotter it gets.
 
The solution to this puzzle lies in the region of the sun known as the chromosphere. This is the layer that lies between the surface and the corona. That is why Nasa has just launched a telescope to take a closer look. For the next two years, the Interface Region Imaging Spectrograph (Iris) will watch the chromosphere from its position in orbit 400 miles above Planet Earth.
 
It’s ironic that Iris’s launch on 27 June was delayed by a power outage that took Vandenberg Air Force Base’s systems offline: that is exactly what Iris may help prevent. The huge quantity of energy trapped in the chromosphere powers the solar wind, a stream of particles that emanates from the sun, as well as events such as the coronal mass ejections that occasionally catapult hundred-billionkilogram gobs of plasma out into space at speeds of up to seven million miles per hour.
 
When those hot plasma balls (they start off at 10m°) head our way, things can get pretty tricky here on earth. Interactions between the plasma balls and the earth’s magnetic field can cause havoc with our power grids and threaten vital infrastructure.
 
The US National Academy of Sciences has estimated that, in a worst-case scenario, a freak space storm could cause a catastrophe that would leave the US government with a repair bill of up to $2trn. Improving our understanding of the chromosphere is one way to tell how badly the sun could hurt us, so the $100m to build Iris and look into the possibilities seems a bargain.
 
The main working part of the spacecraft is a telescope that inspects the ultraviolet radiation coming from the 2,000-mile gap between the surface and the corona. It will take an image every ten seconds or so and analyse the spectrum of radiation for clues to how the heat is moving around to produce such odd changes in temperature. In a couple of years, we may have solved the biggest mystery in our solar system. Then we can sit, shivering under steel-grey skies, marvelling at human scientific ingenuity and wondering why someone can’t do something about the weather.

Craig Oliver, Cameron's attack dog, finally bites

A new book reveals the spiteful after life of Downing Street's unlikely spin doctor.

It must be hard being a spin doctor: always in the shadows but always on-message. The murky control that the role requires might explain why David Cameron’s former director of communications Craig Oliver has rushed out his political memoirs so soon after his boss left Downing Street. Now that he has been freed from the shackles of power, Oliver has chosen to expose the bitterness that lingers among those on the losing side in the EU referendum.

The book, which is aptly titled Unleashing Demons, made headlines with its revelation that Cameron felt “badly let down” by Theresa May during the campaign, and that some in the Remain camp regarded the then home secretary as an “enemy agent”. It makes for gripping reading – yet seems uncharacteristically provocative in style for a man who eschewed the sweary spin doctor stereotype, instead advising Cameron to “be Zen” while Tory civil war raged during the Brexit campaign.

It may be not only politicians who find the book a tough read. Oliver’s visceral account of his side’s defeat on 24 June includes a description of how he staggered in a daze down Whitehall until he retched “harder than I have done in my life. Nothing comes up. I retch again – so hard, it feels as if I’ll turn inside out.”

It’s easy to see why losing hit Oliver – who was knighted in Cameron’s resignation honours list – so hard. Arguably, this was the first time the 47-year-old father-of-three had ever failed at anything. The son of a former police chief constable, he grew up in Scotland, went to a state school and studied English at St Andrews University. He then became a broadcast journalist, holding senior posts at the BBC, ITV and Channel 4.

When the former News of the World editor Andy Coulson resigned as No 10’s communications director in January 2011 because of unceasing references in the press to his alleged involvement in the phone-hacking scandal, Oliver was not the obvious replacement. But he was seen as a scandal-free BBC pen-pusher who exuded calm authority, and that won him the job. The Cameron administration, tainted by its association with the Murdoch media empire, needed somebody uncontroversial who could blend into the background.

It wasn’t just Oliver’s relative blandness that recommended him. At the BBC, he had made his name revamping the corporation’s flagship News at Ten by identifying the news angles that would resonate with Middle England. The Conservatives then put this skill to very good use during their 2015 election campaign. His broadcast expertise also qualified him to sharpen up the then prime minister’s image.

Oliver’s own sense of style, however, was widely ridiculed when he showed up for his first week at Downing Street looking every inch the metropolitan media male with a trendy man bag and expensive Beats by Dre headphones, iPad in hand.

His apparent lack of political affiliation caused a stir at Westminster. Political hacks were perplexed by his anti-spin attitude. His style was the antithesis of the attack-dog mode popularised by Alastair Campbell and Damian McBride in the New Labour years. As Robert Peston told the Daily Mail: “Despite working closely with Oliver for three years, I had no clue about his politics or that he was interested in politics.” Five years on, critics still cast aspersions and question his commitment to the Conservative cause.

Oliver survived despite early wobbles. The most sinister of these was the allegation that in 2012 he tried to prevent the Daily Telegraph publishing a story about expenses claimed by the then culture secretary, Maria Miller, using her links to the Leveson inquiry as leverage – an accusation that Downing Street denied. Nevertheless, he became indispensable to Cameron, one of a handful of trusted advisers always at the prime minister’s side.

Newspapers grumbled about Oliver’s preference for broadcast and social media over print. “He’s made it clear he [Oliver] doesn’t give a s*** about us, so I don’t really give a s*** about him,” a veteran correspondent from a national newspaper told Politico.

Yet that approach was why he was hired. There was the occasional gaffe, including the clumsy shot of a stern-looking Cameron, apparently on the phone to President Obama discussing Putin’s incursion into Ukraine, which was widely mocked on Twitter. But overall, reducing Downing Street’s dependence on print media worked: Scotland voted against independence in 2014 and the Tories won a majority in the 2015 general election.

Then came Brexit, a blow to the whole Cameroon inner circle. In his rush to set the record straight and defend Cameron’s legacy – as well as his own – Oliver has finally broken free of the toned-down, straight-guy persona he perfected in power. His memoir is spiteful and melodramatic, like something straight from the mouth of Malcolm Tucker in The Thick of It. Perhaps, with this vengeful encore to his mild political career, the unlikely spin doctor has finally fulfilled his potential.
