Ice Worms--the Least Charismatic Victims of Climate Change?
The brown squiggles you see here are ice worms making their living on the surface of the Whitechuck Glacier in the Cascade Mountains of Washington State. These relatives of earthworms---seen here alongside a disintegrating balloon littering the ice---are found only on the glaciers of the North American west coast, where they graze on algae and bacteria. Unlike other animals, the worms have a metabolism that seems to increase at lower temperatures; they typically die above 50 degrees Fahrenheit
