Noted photog and National Geographic contributor James Balog leads us on a tour of the glacial north in this stirringly-framed argument against the sins of global warming. It's a three-pronged picture, stuffing a biography, research paper and technical adventure into one seventy-minute package, and often feels scattered as a result.

The science makes for interesting brain food and Balog's personal journey is novel, if a bit overplayed, but the real show-stoppers are his long-form time lapses and breath-stealing snapshots of nature at its most profound. The centerpiece of this film, and of his argument, are a series of three-year-long panoramas in which we clearly watch several glaciers shrink and recede at an alarming rate; a convincing testament to both the presence and speed of the global melt. Though Chasing Ice can certainly be accused of getting caught up in its own self-importance (or lost in the data), those lingering tastes of proof are worth waiting for and the constant presence of Balog's powerful photo portfolio makes the ride there especially sweet.
