This site contains information about snow, glaciers, permafrost, sea ice and cryospheric trends. The cryosphere is the portion of the Earth's surface where water is in a solid form, usually snow or ice. Seasonal snow cover, the largest component of the cryosphere, covers up to 33 percent of the Earth's total land surface. Glaciers and ice sheets cover about 10 percent of the Earth's land area. Nearly 24 percent of the exposed land of the Northern Hemisphere contains permafrost. Sea ice is important because it regulates exchanges of heat, moisture and salinity in the polar oceans.
