Photographing Climate Change

In this audio slide show, James Balog shares the stories behind startling images from his Extreme Ice Survey, a three-year photographic study which documented the unprecedented melting of the world's glaciers and ice sheets. Balog considers himself a modern hunter-gatherer, collecting arresting visual evidence of climate change, which many scientists agree is proof of human-caused global warming.
