Boulders the size of houses and weighing 100 tonnes or more had been lifted up and bulldozed along cliff tops

Winter storms battering the British Isles are more powerful than often assumed. The stormy winter of 2013-14 along the west coast of Ireland produced waves so powerful they tore great slabs of rock out of coastlines and shoved them inland. Among those boulders was a 620-tonne colossus, equivalent to more than three blue whales, which was shoved several feet inshore, setting a new world record for the largest boulder ever known to have been moved by storm waves.

It’s nothing much to look at, but the tangle of pipes, pumps, tanks, reactors, chimneys and ducts on a messy industrial estate outside the logging town of Squamish in western Canada could just provide the fix to stop the world tipping into runaway climate change and substitute dwindling supplies of conventional fuel.

It could also make Harvard superstar physicist David Keith, Microsoft co-founder Bill Gates and oil sands magnate Norman Murray Edwards more money than they could ever dream of.

Critics say these technologies are unfeasible. Not producing the emissions in the first place would be much cleverer

A stint in space showed the ESA astronaut Earth’s fragility – and convinced him international cooperation is urgently needed

As divisions between them widen on Earth, space must be where countries show they can work together for a common good, France’s best-known astronaut has said in a powerful plea for international cooperation beyond the final frontier.

“From up there, the Earth seems so small, so tiny, so … the same,” said Thomas Pesquet, who spent 196 days, 17 hours and 49 minutes in space on the 50th and 51st expeditions to the International Space Station (ISS), returning in June last year.

We’ve come to accept Trump’s ignorance, but it’s often dangerous

Donald Trump has decimated all presidential norms to such a degree that it’s now difficult to feel alarmed or outraged when he inevitably breaks another. It was difficult to raise an eyebrow when the story broke that Trump paid off a porn star to remain silent about their affair, which happened just after his third wife had given birth to his fifth child, because it’s Donald Trump – of course he did.

Likewise, when Trump made a number of grossly ignorant and wrong comments about climate change in an interview with Piers Morgan last week, my first reaction was ‘it’s Donald Trump – of course he did.’

I believe in clean air. I believe in crystal-clear, beautiful … I believe in just having good cleanliness in all. Now, with that being said, if somebody said go back into the Paris accord, it would have to be a completely different deal because we had a horrible deal.
