Extreme Ice: A new NOVA film on glacial melting

Email a Friend

When we use the metaphor of things moving at a glacial pace, our intention is to describe something progressing very slowly. Well if you were familiar with James Balog and his nature photography, chances are you’d never use that phrase that way again. James Balog is the founder and director of the Extreme Ice Survey. With the use of 26 time-lapse cameras, Balog and his colleagues document the rapid changes on glaciers across the Northern Hemisphere. You can see Balog in action, trekking through treacherous terrain, in a new NOVA and National Geographic documentary, Extreme Ice. You can also check out Balog's photography in his latest book, Extreme Ice Now: Vanishing Glaciers and Changing Climate: A Progress Report.
