the Discovery channel has a pretty cool video NASA made of the icy Earth. http://dsc.discovery.com/news/media/frozenearthvideo.html very imformative... watch an ice shelf on tha Anartica coast formed over 25,000 years melt in 5 weeks via time lasped photography. or an ice flow on the west coast of Greenland recede in the past 4 years more than it has since 1542... very cool
