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

This data set compares global atmospheric concentration of methane from ice cores taken on the ice sheets of Antarctica and Greenland. The data come from multiple ice cores on each continent, ...

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 ...
