This site provides time-series data for Northern Hemisphere snow cover, mountain glacier fluctuations, sea ice extent and concentration, changes in ice shelves, and global sea level. It also provides a snapshot of current permafrost conditions.

Introduction: Are global temperatures rising?

Northern Hemisphere Snow: What satellite sensors are telling us about snow cover Glaciers: Mountain glacier fluctuations Permafrost and Frozen Ground: Insights from a Northern Hemisphere map and field observations

Sea Ice: What satellite sensors are telling us about global sea ice extent and concentration Ice Shelves: Rapid response to climate change Sea Level: Is global sea level rising? Scientific References
