Chasing Ice (Trailer)

Chasing Ice tells the story of nature photographer James Balog and the findings of his Extreme Ice Survey, a project that set out to study and expose the impact of global warming.

Balog, who was once sceptical about climate change, travels to Greenland and Alaska to capture images that communicate the effects of human activity on the climate. His Extreme Ice Survey is an expedition that uses time-lapse photography to collect multi-year data on the seasonal changes of glaciers across the Arctic.

The documentary features real footage of a glacier calving event at Greenland’s Jakobshavn Glacier. The event lasted 75 minutes, making it the longest of its kind ever captured on film. To record it, two photographers camped in a tent overlooking the glacier for several weeks. They were eventually able to witness 7.4 cubic kilometres of ice crashing from the glacier.
