Art meets science in photographer James Balog's Extreme Ice Survey. The project, begun in December 2006, will attempt to capture global warming in the act using 26 solar-powered cameras taking time-lapse photographs of glaciers in Greenland, Iceland, Alaska, the Alps, and the Rocky Mountains. Balog hopes the ambitious effort, which will produce more than 300,000 images over the course of two years, "radically alters public perception of the global warming issue."
