Chasing Ice is a 2012 documentary film about the efforts of nature photographer James Balog and his Extreme Ice Survey (EIS) to publicize the effects of climate change, directed by Jeff Orlowski. It was released in the United States on November 16, 2012.
The documentary includes scenes from a glacier calving event that took place at Jakobshavn Glacier in Greenland, lasting 75 minutes, the longest such event ever captured on film. Two EIS videographers waited several weeks in a small tent overlooking the glacier, and were finally able to witness 7.4 cubic kilometres (1.8 cu mi) of ice crashing off the glacier. "The calving of a massive glacier believed to have produced the ice that sank the Titanic is like watching a city break apart."
