Chasing Ice (2012)

'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 'Chasing Ice,' we follow Balog across the Arctic as he deploys revolutionary time-lapse cameras designed for one purpose: to capture a multi-year record of the world's changing glaciers. Balog's hauntingly beautiful videos compress years into seconds and capture ancient mountains of ice in motion as they disappear at a breathtaking rate. Traveling with a young team of adventurers by helicopter, canoe and dog sled across three continents, Balog risks his career and his well-being in pursuit of the biggest story in human history. As the debate polarizes America and the intensity of natural disasters ramp up around the world, 'Chasing Ice' depicts a heroic photojournalist on a mission to gather evidence and deliver hope to our carbon-powered planet
