Has anyone seen the movie Chasing Ice? It's about all the glaciers shrinking around the world and geologic events happening during a lifetime....it's super awesome. Check it. http://www.chasingice.com/
Just watched it the other night. Aside from the sob story about Balog's knee, it was great. It gives some tangible evidence and is really just appalling to see how bad it actually is getting. I can't believe they stuck around that glacier for two weeks, recording every waking moment only to be on the phone with Balog when the glacier started to calve.
If you are cheap, its available on tpb. Everyone, just watch it.
