Scientists claim they can fight global warming by firing trillions of mirrors into space to deflect the sun's rays forming a 100,000 square mile "sun shade".
According to astronomer Dr Roger Angel, at the University of Arizona, the trillions of mirrors would have to be fired one million miles above the earth using a huge cannon with a barrel of 0.6 miles across.
The gun would pack 100 times the power of conventional weapons and need an exclusion zone of several miles before being fired.
Despite the obvious obstacles—including an estimated $350 trillion (£244trn) price tag for the project—Dr Angel is confident of getting the project off the ground.
If Dr Angel's sun shield is successful he says the mirrors will last 50 years before needing to be replaced.
"What you are talking about is a project which will stop global warming for centuries to come," he said.
No, Dr Angel: if this stupid idea actually worked, what you are talking about is plunging the Earth into a catastrophic ice-age from which it wouldn't recover for at least 50 years. Or rather, the Earth will be absolutely fine: mankind would be wiped out.
You know, all of those great British post-apocalyptic sci-fi writers were right—aided by pig-ignorant, evil politicians, insane scientists will, indeed, destroy us all. The only bit that said writers got wrong was that the apocalypse would be delivered by nuclear weapons.
