The CIFF Selects series will screen the documentary “Chasing Ice” Thursday, March 14 at 6 p.m. at Unity College Center for the Performing Arts, 42 Depot St. Admission s free, sponsored by the Unity College Center for Environmental Arts and Humanities.

In the spring of 2005, acclaimed environmental photographer James Balog headed to the Arctic on a tricky assignment for National Geographic: to capture images to help tell the story of the Earth’s changing climate. Even with a scientific upbringing, Balog had been a skeptic about climate change. But that first trip north opened his eyes to the biggest story in human history and sparked a challenge within him that would put his career and his very well-being at risk.

“Chasing Ice” is the story of one man’s mission to change the tide of history by gathering undeniable evidence of our changing planet. Within months of that first trip to Iceland, the photographer conceived the boldest expedition of his life — the Extreme Ice Survey. With a band of young adventurers in tow, Balog began deploying revolutionary time-lapse cameras across the brutal Arctic to capture a multi-year record of the world’s changing glaciers.

As the debate polarizes America and the intensity of natural disasters ramps up globally, Balog finds himself at the end of his tether. Battling untested technology in subzero conditions, he comes face to face with his own mortality. It takes years for Balog to see the fruits of his labor; “Chasing Ice” concludes with haunting video compressions that capture ancient mountains of ice in motion as they disappear at a breathtaking rate.

“Chasing Ice” was the Closing Night Film at the 2012 Camden International Film Festival. CIFF is recognized as one of the top 25 film festivals in the world for documentary films and filmmakers. For more information, visit camdenfilmfest.org.
