Clouds and Climate Change

Here's another interesting article about global warming that I just found, well, interesting. First, a quote:

"It's a new science, driven by the fact that everybody doing climate predictions says that clouds are perhaps the single greatest unknown factor in understanding global warming."

I love how they say that, then spend the rest of the article explaining how it's not unknown at all and how the Earth is in death throes. Could we make up our minds, please?

Either way, the part that grabbed my attention was this:

"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).

Liquid water at -30? Too cool. (That was intentional)
