I was fortunate to spend a few weeks recently with the director of Chasing Ice, Jeff Orlowski. I'm going to plug Chasing Ice because it's an amazing film. Jeff along with EIS (http://extremeicesurvey.org/) filmed glaciers for a few years. The images and film captured of the glaciers receding and calving is remarkable. I encourage everyone to go out and see it. It's won tons of film festival awards.
