James Balog is a phenomenal photographer. In 2005 National Geographic sent him to the Arctic on assignment to document earth’s changing climate. Balog was somewhat skeptical, but after a single visit to the Arctic he says his eyes were opened to the severity of climate change. Eight years later he’s become the focus of the documentary Chasing Ice, which chronicles Balog and his crew as they scramble to record glaciers as they disappear forever. The film’s synopsis spells it out: "It’s the story of one man’s mission to change the tide of history by gathering undeniable evidence of our changing planet." The film looks gorgeous and riveting, and can still be found in some theaters throughout the country. If it’s not playing in your area, though, you can log on to the web site to help bring the film to a theater near you—which you might have to do, as there’s no DVD available yet.
