Sea ice extent in Arctic and Antarctic reached record lows in November

From The Guardian:

“Both the Arctic and Antarctic experienced record lows in sea ice extent in November, with scientists astonished to see Arctic ice actually retreating at a time when the region enters the cold darkness of winter.

Warm temperatures and winds drove record declines in sea ice at both polar regions in November compared to the 38-year satellite record of ice extent for the month. Arctic sea ice extent averaged 9.08m sq km (3.51m sq miles) for November, which is 1.95m sq km (or 753,000 sq miles) below the long-term average from 1981 to 2010 for the month.

Scientists at the National Snow and Ice Data Center (NSIDC) said that Arctic sea ice extent dipped for a short time in mid-November, an “almost unprecedented” event. Sea ice shrank by around 50,000 sq km (19,300 sq miles) in this period, mainly in the Barents Sea.

This decline, which also occurred to a smaller degree in November 2013, removed an area of ice larger than Denmark from the Arctic at a time when sea ice is usually growing.”
