The first showing of the PBS NOVA episode "Extreme Ice" was tonight. I am not a scientist, a climatologist or political agitator but the show itself was compelling. James Balog is a photographer and scientist who photographed disappearing glaciers around the world for National Geographic (June 1997 cover story: The Big Thaw"). Since that time he has installed cameras in Alaska, Greenland, Iceland and the Rockies, each taking one time-lapse photograph per hour, every hour, over the course of years. The resulting footage is astonishing, documenting the retreat of glaciers that is claimed to be at eight times the normal historical rate. There are photos and video at Extreme Ice Survey's site. The entire program will be available at NOVA's site beginning March 25th.(photo via PBS.org)
