Acclaimed National Geographic photographer James Balog was once skeptical about climate change. But through his Extreme Ice Survey, he discovers definitive evidence of our changing planet. In this documentary, Balog uses time-lapse cameras to capture a multi-year record of the world's glaciers. His videos compress years into seconds and capture ancient mountains of ice in motion as they vanish at an astonishing rate. Traveling with a team across the brutal Arctic, Balog risks his career and his health in pursuit of the biggest story facing humanity. As the debate polarizes America, and the intensity of natural disasters ramps up globally, Chasing Ice depicts a photojournalist on a mission to deliver fragile hope to our carbon-powered planet.
