Glaciers in retreat: The Extreme Ice Survey

The Extreme Ice Survey collects visual evidence of the impact of global warming on our planet, like time-lapse photos of the contraction of the glaciers.  Outside of the Antarctic, 95% of the world’s glaciers are retreating.

See the film “Chasing Ice”, produced in cooperation with National Geographic. It won an Emmy award as an outstanding nature program.
