Glacial retreat. Image 2 of 2. McCarty Glacier, Kenai Fjords National Park, Alaska, in 2004. In recent years, McCarty Glacier has retreated dramatically and is not visible compared to the same spot in 1909 (image E235/386). 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.
