Ice recovery – It even exceeds the 2001-2010 average size.
12 Feb 2020 – The latest sea ice analysis shows that during this rather mild winter in the mid-latitudes, the trapping of the colder air in the polar circle was beneficial to the growth and recovery of the polar icecap.
Every winter the Arctic ocean freezes, reaching a maximum sea ice extent around March. The stronger than normal polar vortex has helped to keep more cold air in the polar regions, promoting ice growth.
Here’s a different perspective:
Arctic sea ice has actually shown great resiliency
Sea ice covers about 7% of the Earth’s surface and about 12% of the world’s oceans and forms mainly in the Earth’s polar regions. Specifically, much of the world’s sea ice is found within the Arctic ice pack of the Arctic Ocean in the Northern Hemisphere and the Antarctic ice pack of the Southern Ocean in the Southern Hemisphere. While the Antarctic sea ice extent is currently running at levels very close-to-normal, the Arctic sea ice extent is below-normal and has been running generally at below-normal levels since the middle 1990’s at which time there was a long-term phase shift from cold-to-warm in the North Atlantic Ocean sea surface temperature pattern. In recent years, however, the Arctic sea ice has actually shown great resiliency and is currently at higher levels for this time of year when compared to all but two years going back to 2005.
