The Cryosphere includes all frozen water on the Earth's surface, all areas where snow, ice and permafrost affect the landscape and processes occurring there. We find a big amount of water tied up in glaciers and icecaps in Arctic and Antarctic, but also in permafrost and smaller glaciers worldwide.

A large international study - Global Land Ice Measurements from Space (GLIMS) shows that Earth’s glaciers are shrinking with only a few exceptions. The scientists behind the study have applied satellite images to study the glaciers over the recent decades. The comprehensive report is now published as a book and an e-book.
