As the frozen parts of our planet face rapid and unprecedented change, NSIDC has been sharing how and why its key features are changing.

The global GFDL SPEAR large ensemble climate change simulations were produced by a 30-member ensemble over the period of 1921-2100. The SPEAR climate model was run using historical radiative forcing ...

Arctic daily sea ice extent continued to hover near record daily lows in January, with the ice edge well northward of its long-term average position in most areas. In contrast to the cold conditions ...

The Circumpolar Arctic Vegetation Map (CAVM) defines the spatial extent of dominant vegetation in terms of the dominant plant growth forms and physiognomy. Mapped vegetation extends south to the ...
