(CNN) – Climate change is a polarizing issue. So photographer James Balog traveled towards Earth's poles to bring back tangible, visual, and hauntingly beautiful evidence of a dramatic geological event that affects every human being on this planet.
In the award-winning documentary "Chasing Ice," Balog and his team braved some of the globe's most extreme conditions to reach glaciers in Greenland, Iceland, Alaska, and Montana, and brought back years' worth of time lapse photography. Balog's cameras have been there to watch as hunks of ice bigger than lower Manhattan just disappear.
The results are irrefutable, something is terribly wrong, and Balog, along with the vast majority of climate scientists, say humans are to blame.
Now, Balog is doing the same thing in Antarctica, setting up more cameras, to bring us all more evidence of what the Secretary of State has called "perhaps the world's most fearsome weapon of mass destruction."
