A wonderful surprise this evening. The National Geographic channel aired James Balog’s film Chasing Ice, which I never got to see in the theater. I wrote about it last November. It airs several more times in the next week, no doubt to coincide with Earth Day. I’d like to think it would change the minds of some of those who despise Al Gore and think all his Inconvenient Truth charts and figures were misinterpretations — or worse — but I’m afraid only “climate change believers” will watch it. What a shame. Photographic evidence is hard to deny and the glacier calving and time-lapse shots in the last half-hour are not to be missed. This should be required viewing for Earth Day on April 22.
