Cryosphere

The word cryosphere comes from the Greek word cryos meaning "cold" or "ice." It includes the part of the planet's surface covered in snow or ice, including glaciers, ice caps, ice sheets, and sea ice. These days, much of the planet's cryosphere has come under threat from rising temperatures. Planet Diary tracks this global meltdown and reports on efforts to slow it down.
