According to satellite tv for pc observations, Arctic sea ice reached its annual minimal extent on Sept. 18, 2022. The ice cowl shrank to an space of 4.67 million sq. kilometers (1.80 million sq. miles) this yr, roughly 1.55 million sq. kilometers (598,000 sq. miles) under the 1981-2010 common minimal of 6.22 million sq. kilometers (2.40 million sq. miles).

Summer ice extent in and across the Arctic Ocean has declined considerably since satellites started measuring it constantly in 1978. The previous 16 years (2007 to 2022) have been the bottom 16 minimal extents, with 2022 tying 2017 and 2018 for Tenth-lowest in 44 years of observations. The satellite tv for pc document is maintained by the National Snow and Ice Data Center (NSIDC), which hosts one in all NASA’s Distributed Active Archive Centers.

“This year marks a continuation of the much-reduced sea ice cover since the 1980s,” stated Walt Meier, a sea ice researcher on the National Snow and Ice Data Center. “That is not something that is random variations or chance. It represents a fundamental change in the ice cover in response to warming temperatures.”

Each yr, Arctic sea ice melts by the hotter spring and summer season months and often reaches its minimal extent in September. As cooler climate and winter darkness units in, the ice will develop once more and attain its most extent round March.

Sea ice extent is outlined as the full space during which ice focus is at the least 15%. This visualization, created at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, exhibits fluctuations in Arctic sea ice extent from March by September 2022. The map relies on knowledge acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument on the Japan Aerospace Exploration Agency’s Global Change Observation Mission 1st-Water “SHIZUKU” (GCOM-W1) satellite tv for pc.
