Scientists: Climate Change Clues in Sky

Excuse us for our lack of optimism, but we think we are already too far down the pike to be able to do much more than prevent a very devastating landing.

Even for that, we must begin today. How likely is that, with the fossel fuel guys in charge of the world?

Scientists: Climate Change Clues in Sky:

Scientists are peering into the clouds near the top of the world, trying to solve a mystery and learn something new about global warming.

The mystery is the droplets of water in the clouds. With the North Pole just 685 miles away, they should be frozen, yet more of them are liquid than anyone expected.

So the scientists working out of a converted blue cargo container are trying to determine whether the clouds are one of the causes — or effects — of Earth's warming atmosphere.

'Much to our surprise, we found that Arctic clouds have got lots of super-cooled liquid water in them. Liquid water has even been detected in clouds at temperatures as low as minus 30 degrees Celsius (minus 22 F),' said Taneil Uttal, chief of the Clouds and Arctic Research Group at the Earth Systems Research Laboratory of the U.S. National Oceanic and Atmospheric Administration (NOAA).
