A polar parasol! Now why didn't WE think of that?

You simply cannot make this stuff up:

THE idea seems like something out of a Superman comic: a machine or missile shoots tonnes of particles into the atmosphere that would block the Sun's rays, cool down the overheated Earth, and reverse global warming.

But at the weekend scientists gathered in a closed session organised by NASA and Stanford University to discuss researching such a strategy. The idea is called geo-engineering: using technology to tinker with the Earth's delicate climate balance.

Ken Caldeira, a climate scientist at the Carnegie Institution's Department of Global Ecology at Stanford University, said his modelling showed the idea worked. "We found that if you blocked 20 per cent of the sunlight over the Arctic Ocean it would be enough to restore sea ice," he said.

I wonder how they're going to do that...perhaps buy a bunch of semi tractor-trailers or take a bunch of New York City buses up there and let them belch out enough exhaust to create smog?

And am I the only one who thought about the Rod Serling story/Twilight Zone episode The Midnight Sun after reading this?
