Documentary showing the impact of climate change on the world's ice caps. The film follows National Geographic photojournalist James Balog, a former skeptic about climate change, as he uses time-lapse cameras to capture a record of the world's changing ice landscapes over a period of several years. Making his expedition by helicopter, canoe and dog sled across three continents, Balog gathers his seemingly irrefutable evidence of the melting ice caps in an attempt to convince those who continue to deny the effects of climate change.
