Paris (ESA) May 26, 2023 -
Earth s declining ice is without a doubt one of the clearest signs of climate change. A new high-resolution sea-ice concentration data record has just been released as part of ESA s Climate Change I
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.
