Arctic Sea Ice: How Long 'til It's Gone?

Imagine trekking 600 miles by foot over 100 days, enduring -40 degree Celsius temperatures. That's currently what a team of three extremely experienced polar explorers are doing--all in the name of science. Their goal is to map the Arctic's sea ice with state-of-the-art impulse radar technology--the first detailed mapping of its kind. The survey will significantly improve the accuracy and reliability of computer models forecasting the timing of the ice cap's disappearance, and the associated impacts on the global climate.
