South Cascade Glacier, in North Cascades National Park, shrank tremendously from 1928 to 2010  What's going on here?    [images from NSIDC]

In the polar regions, many glaciers end in the ocean. This is Barne Glacier, on Ross Island in Antarctica. Could these glaciers be threatened by rising ocean temperatures? By rising sea level?

This is Earth's third-biggest glacier. Ice cores have been drilled at the labeled sites, to recover past climate information, with some records going back well over 100,000 years.
