So, this below is from the Cornerhouse website. And below that, a clip of a climate denialist who “converted” after seeing the documentary…

Acclaimed environmental 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, Balog deploys revolutionary time-lapse cameras to capture a multi-year record of the world’s changing glaciers. His hauntingly beautiful videos capture ancient mountains of ice in motion as they disappear at a breathtaking rate. Traveling with a team of young adventurers across the brutal Arctic, Balog risks his career and his well-being in pursuit of the biggest story facing humanity. As the debate polarises America, and the intensity of natural disasters ramps up globally, Chasing Ice depicts a heroic photojournalist on a mission to deliver fragile hope to our carbon-powered planet.
