Glacial retreat. Image 2 of 2. Northwestern Glacier, Kenai Fjords National Park, Alaska, in 2005. Compared to a photograph taken from the same point in 1940 (E235/402), the glacier has retreated from view and surrounding ice has disappeared. Glaciers are large, slow-moving expanses of ice, formed from compacted layers of snow. They are sensitive to climate change and in recent years most have retreated dramatically. The National Snow and Ice Data Center (NSIDC) is a US body that supports research into snow, ice, glaciers, frozen ground and climate interactions that make up the Earth's cryosphere. The World Data Center for Glaciology (WDC) in Boulder, USA, is responsible for archiving all available glaciological information.
