A Tour of the Cryosphere

This NASA video combines a variety of imagery from satellites to provide "fly-overs" of Earth from space to illustrate the features of the cryosphere and their dynamics: Sea ice cover, Antarctic ice sheets, glaciers, and snow cover with good 3-D relief.

The video and text do a good job of fleshing out the concluding message:? "For many reasons, the cryosphere is important to the global climate."
