NSIDC: Arctic freeze-up well underway, November snow cover over North America most extensive since 1966

The Arctic freeze-up season is well underway, with ice extent increasing faster than average for most regions in November. Exceptions were in the Chukchi and Barents Seas, where the ice has been slow to form. Meanwhile, November snow cover over North America was the most extensive since 1966, the National Snow and Ice Data Center (NSIDC) reported in their analysis released December 4, 2018.

Arctic sea ice extent for November averaged 9.80 million km2 (3.78 million mi2), the center reports. This was the 9th lowest November in the 1979 to 2018 satellite record, falling 900 000 km2 (347 000 mi2) below the 1981 to 2010 average, yet 1.14 million km2 (440 000 mi2) above the record November low in 2016.
