Om 15 september 2020 bereikte het zee-ijs op de noordpool waarschijnlijk het minimum van 2020 wat betreft de bedekking van zee met minimaal 15% zee-ijs. Het minimum was het op één na laagste minimum van 42 jaar satelliet data, alleen op 17 september 2012 was er een nog lagere ijsbedekking.

Arctic sea ice decline stalls out at second lowest minimum

September 21, 2020

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. Sea ice extent will now begin its seasonal increase through autumn and winter. In the Antarctic, sea ice extent is now well above average and within the range of the ten largest ice extents on record, underscoring its high year-to-year variability. The annual maximum for Antarctic sea ice typically occurs in late September or early October.

Please note that this is a preliminary announcement. Changing winds or late-season melt could still reduce the Arctic ice extent, as happened in 2005 and 2010. NSIDC scientists will release a full analysis of the Arctic melt season, and discuss the Antarctic winter sea ice growth, in early October.
