Science Nation: Alaska Mountain Glaciers Retreating Due to Climate Change

3 minutes 40 seconds

Now Playing As: Captioned (English) (change)

Welcome to Ruth Glacier, deep inside Alaska’s Denali National Park and Preserve. Some of the visitors are here for recreational activities, such as backcountry skiing, but this is no vacation for University of Maine paleoclimatologist Karl Kreutz and his team. For them, time on the ice is all part of the job. With support from the National Science Foundation, the scientists are working to reconstruct the climate history of this area over the last thousand years. Part of the National Science Foundation Series “Science Nation.”
