Climatologist: Alps warmest in 1,300 years

That's right, everyone. Better enjoy what little snow we have, because it's getting more and more difficult for ski resorts to produce a viable hill. We're actually doing pretty well in the rockies, but the Alps are not. So far this year, the FIS has had to cancel several races in Europe due to a lack of snow. Val Gardena is getting a weak green for next weekend, presuming they can keep the hill covered.

FIS men's tour director, Guenter Hujara talked about how it sneaks up on you. "... all of a sudden the World Cup starts and you need the white stuff. And to produce it, you need the cold temperature and the water."

How much human migration will take place over the next 20 years? Will people be driven by the heat to move towards the poles? Will old resorts have to close down, and new ones emerge in once-frozen regions?

Here is a striking example of just how much our planet has warmed up over the past 60 years. It's a pair of pictures of Muir glacier, in Alaska. One was taken in 1941, and the other in 2004.
