On December 10, 1972, the world of sea ice data changed forever. For the first time in history, as the Electrically Scanning Microwave Radiometer (ESMR) launched aboard the NASA Nimbus-5 satellite, scientists gained the ability to track changes in sea ice cover over the Polar Regions every day via passive microwave data. Today, they can piece together a half century’s worth of data from several instruments and satellite missions, including ESMR, to better understand how global warming is affecting Arctic and Antarctic sea ice.

While most of the 2022 Greenland melt season was near average, September set records for high temperatures, melt extent, and ice loss.
Feature Story
Through partnerships with community members and vital climate information recorded by volunteers in local observer networks, NSIDC's Arctic Rain on Snow Study (AROSS) aims to better understand rain on snow events and other winter precipitation changes—with a focus on how they impact peoples in the Arctic.
