In March, a six-member team from the United States, Norway, Great Britain, and Canada will embark on a 1,400 mile dogsled expedition across Ellesmere Island. As the team traces the routes of legendary polar explorers such as Robert Peary, Matthew Hensen, Frederick Cook, and Otto Sverdrup, they will witness the changes that have occurred on the third largest island in the Canadian Arctic and document the impact of global warming . The 60-day expedition is an initiative of the Will Steger Foundation and will operate in conjunction with the National Geographic Society, the International Polar Year, Extreme Ice Survey, and the Royal Norwegian Embassy. Team members will document the expedition and share findings through video, images, sounds, and text. Blogs and podcasts will detail the journey as well as profile the five young people working to slow global warming in their communities and nations.
