Tracking Arctic sea-ice growth
Chris Norman
From the National Snow and Ice Data Center, December 2017.
Concealed in the “Overview of conditions” the following words:
“Arctic sea ice extent for November 2017 averaged 9.46 million square kilometers……………830,000 square kilometers (321,000 square miles) above the record low November extent recorded in 2016…………………….”

One year later, December 2018 “Arctic sea ice extent for November averaged 9.80 million square kilometers (3.78 million square miles)…………………1.14 million square kilometer
Summary:
Nov 2016 the arctic sea ice extent was 8.66 million square kilometers. Nov 2017 9.46 million. Nov 2018 9.80 million.

Note from editor:
In other words, sea ice extent grew 1,140,000 sq miles from Nov 2016 to Nov 2018.
That’s enough EXTRA ice to entirely cover all six New England states, plus the states of New Jersey, Maryland, New York, Kentucky, Indiana, North Carolina, South Carolina, Virginia and Tennessee.
That ought to be enough ice to make a few polar bears happy.
Looks like a fine recovery.
8.66. 9.46. 9.80. The Arctic ice grows.
Note: The entire United States, including Alaska and Hawaii, covers an area of 9.8 million square km, which matches the Arctic sea-ice extent for November 2018.
