Future Earth and the Cryosphere
The term "cryosphere" (deriving from the Greek word kryos for frost or icy cold) is used to describe collectively those portions of the Earth's surface where water is in a solid form. It includes sea, lake, and river ice, snow cover, glaciers, ice caps and ice sheets, and frozen grou...

The term "cryosphere" (deriving from the Greek word kryos for frost or icy cold) is used to describe collectively those portions of the Earth's surface where water is in a solid form. It includes sea, lake, and river ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground (including permafrost). While the focus of this chapter is on geodetic issues and Future Earth, which primarily involves ice sheets and glaciers on land and their role in global mass redistribution and sea level, the cryosphere as a whole is an integral part of the global climate system with important links and feedbacks generated through its influence on surface energy and moisture fluxes, clouds, precipitation, hydrology, and atmospheric and oceanic circulation.
