NASA | A Tour of the Cryosphere 2009

The video explores the impact of polar regions on global climate, starting with Antarctica's ice dynamics and the formation of icebergs. It discusses the role of sea ice in ocean circulation and climate, the shrinking of global glaciers, and the significance of permafrost. The video highlights changes in Greenland's ice sheet and the importance of NASA's satellite observations in understanding cryospheric processes.

What is permafrost and where is it commonly found?

What are the potential consequences of an ice-free Arctic Ocean in the summer by the end of the century?

How has the flow rate of Greenland's Jakobshavn ice stream changed in recent years?
