Arctic Ice Extents have roughly doubled since the Sept. minimum and are now up to 10M km2. The last 1/3 of maximum will take until March, principally because several basins are frozen over and cannot add coverage. To date, Beaufort and CAA (Canadian Archipelago) are full, as are Laptev and East Siberian on the Russian side. Kara is 3/4 covered and the Central Arctic wil add only 3% from here.
During the first half of November we can see at the bottom Beaufort and East Siberian filling in, leaving only Chukchi with open water. On the right, Both Baffin and Hudson bays are now growing more strongly. At the top Kara ice extent has reached 75% of its March maximum.
The graph compares extents over the first 17 days of November.
2017 has reached 9.9M km2, 2007 nearly the same, and both are close to…
