This picture shows how openings in sea ice, known as polynya, help create cold, dense water that protects the base of a glacier from the melting effects of warmer ocean water.

Why is Antarctica's Totten Glacier shrinking faster than its neighbors?

For years, climate scientists have watched with concern as an ice sheet in Western Antarctica has steadily decreased in mass. Recently more attention is being paid to the Eastern side of the continent at the bottom of the world.

A new study from scientists at NASA's Jet Propulsion Laboratory in Pasadena finds some glaciers there are also shrinking, and one in particular is melting much faster than others around it.

From the KPCC Science Desk, Sanden Totten has more.
