Quite possibly the best movie l saw in 2013 didnt open in 3,000 theaters, didnt have a Morgan Freeman voiceover, didnt follow a hobbit and his ring.

The stunningly beautiful, award-winning documentary Chasing Ice was a simple story of a hero on his quest. But no princess needed rescuing, no pirates were fought. The hero, National Geographic photographer James Balog, was attempting something even more difficult: to photograph climate change by capturing the movement of walls of ice as long and high as aircraft carriers.

The word glacial has traditionally been an analogy for extremely slow. Based on what I saw in Chasing Ice, that definition may need to be replaced (I suggest Congressional). At great cost to his health and comfort, Balog and his team trek through some of the worlds most grueling terrain to install time-lapse cameras to document the retreat of glaciers.

And retreat they do, hundreds of feet or more per year. Historically, it used to take decades and even centuries for glaciers to pull back up their mountain valleys. Now, a couple seasons is all it takes for any one of the majority of the worlds ice walls to quite obviously shrink. The glaciers are melting as fast as the Wicked Witch in the Wizard of Oz, but there is no joy in Munchkinland to accompany their demise.

Why is this important? I think its because the environmental movement has always struggled with the incremental pace of regional or even global disasters. The massive changes we humans are forcing on our planet too often occur in the background, under the radar, and at a snails pace. For our minute-to-minute, 24-hour-news, gotta run culture, climate change has been too slow, too widespread, and too complicated.

Thats how I felt, anyway, until I saw Chasing Ice. This is not a movie about slowly migrating species, silent extinctions, or incrementally rising seas. Near the end of the film, Balogs assistants camp out for three weeks overlooking one of the largest glaciers in the world. As if on cue, the glacier collapses. Only when the camera pulls back to reveal that an island of ice THE SIZE OF MANHATTAN has just flipped over does the full weight of the movie hit. (Editor: Factchecking... that should be "an island of ice the size of lower Manhattan" -- but it's still impressive and unprecedented filmmaking. Click the link to watch the clip.) This is what a warming world looks like, made massive, visible, and terrifyingly sudden.

The largest steps forward by the environmental movement have happened when catastrophes like burning rivers, acid rain, oil spills, and superstorms have made themselves impossible to ignore. The creeping hockey stick graph of carbon dioxide levels from NOAAs Mauna Loa observatory just didnt do it for most folks. I say: look to the ice now if you want to know whats happening.

This is usually a week when we marvel at how the past year has flown by. To glaciers, each new year now brings nothing less than amputation. My resolution is to ponder that, and this: when the canaries start keeling over, its time to leave the coal mine. Except that leaving this mine called Earth isnt an option, so weve got to figure out Plan B. Lets get to it.

Happy new year!
