Professor Aaron Doering and the GoNorth! team are holed up at Thule Air Base, Greenland, pinned down by a blizzard. No one is even allowed outside of buildings, as winds gust upwards of 80 miles per hour. Read the complete blog post and follow them on their two-month journey.

The Thule base is GoNorth's point of disembarkation for Greenland 2010. The Polar Huskies plan to celebrate Earth Day on the trail climbing 10,000 feet to the top of Greenland's Ice Sheet. Follow their route to Siorapaluk, Greenland--the northernmost community in the world--and learn about climate change along the way.
