"Extreme Ice Survey" Hits the Silver Screen

Jan 27, 2012

Today Science Questions presents a one-hour Sundance Film Festival special broadcast profiling one of the festival's documentary film highlights, Chasing Ice.

Photographer James Balog turned his 2007 National Geographic cover story about melting glaciers into a monumental five-year photography project about climate change. The documentary, directed by Jeff Orlowski, follows Balog's "extreme ice survey" -- an experiment that placed time-lapse cameras across three continents to capture massive ice melting and the effects of climate change.
