Extreme Ice

The PBS series NOVA has teamed up with National Geographic on a project called "Extreme Ice." The series follows adventure photographer James Balog (read the Fresh Air interview here) and a team of scientists through the world's icy regions in the largest-ever photographic study of the cryosphere.

The documentary allows viewers to follow Balog into treacherous yet breathtaking regions where no camera has gone before. The film corresponds with the release of Balog's book, Extreme Ice Now: Vanishing Glaciers and Changing Climate: A Progress Report, published by National Geographic.

Once a climate change skeptic, Balog here presents stirring time-lapse images of melting bodies of ice. By placing cameras throughout the Arctic and programming them to shoot one frame every daylight hour for three years, he and his team were able to capture unprecedented footage of the world in flux. The gathered evidence points to extreme melting in polar regions. But it also suggests that the effects of climate change are occurring at a much more accelerated rate than previously thought. Extreme Ice explores the potential implications of this undeniable "big melt."

Extreme Ice premieres on March 24. To view more of Balog's photography, as well as video and notes from the field, check out the Extreme Ice Survey Web site.
