The above clip from ‘Chasing Ice’, a documentary film about the efforts of nature photographer James Balog to publicize the effects of climate change, is simply stunning. On May 28, 2008, Adam LeWinter and director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water. When they introduce Manhattan for scale, you get a sense of how big this event was. The film is available on Netflix and I’ve added it to my watch list.
