Acclaimed National Geographic photographer James Balog was once a skeptic about climate change. But through his “Extreme Ice Survey”, he discovers undeniable evidence of our changing planet. In Jeff Orlowski’s docu CHASING ICE (2012, 74 min), Balog deploys revolutionary time-lapse cameras to capture a multi-year record of the world's changing glaciers. His hauntingly beautiful videos compress years into seconds and capture ancient mountains of ice in motion as they disappear at a breathtaking rate.
