Arctic Sea ice cover shrinks to the second-lowest extent

NASA scientists and researchers at the University of Colorado Boulder’s National Snow and Ice Data Center (NSIDC) have reported that analysis of satellite data shows the 2020 minimum extent of ocean covered in ice, 3.74 million square kilometers, was likely reached September 15. 

According to the NSIDC. on September 15, Arctic sea ice likely reached its annual minimum extent of 3.74 million square kilometers (1.44 million square miles). The minimum ice extent is the second lowest in the 42-year-old satellite record, reinforcing the long-term downward trend in Arctic ice extent. 

A sharp decline of Arctic sea ice at the beginning of September dropped the extent below 4.0 million square kilometers (1.54 million square miles) for only the second time since the beginning of the satellite record in 1979.
