Efffect of Global Warming on the Bering Glacier

The Global Fiducials Library (GFL) is a long-term archive of images from U.S. National Imagery Systems which represents a long-term periodic record for selected scientifically important sites.

Here is an imagery from that site that reveals how much the Bering Glacier has retreated, presumably as a result of Global Warming.
"Bering Glacier is the largest and longest glacier in continental North America. In 1996, its size reached a late twentieth-century maximum. Since then, parts of Bering Glacier's terminus have retreated more than three miles and have thinned by more than 200 feet. These images below document the 1996-2005 retreat of Bering Glacier and show an example of the long-term monitoring required to accurately assess the state of the glacier."
