Arctic Sea Ice 2022-2023
Posted: Tue 22 Mar 2022, 10:57:34
By what can only be called a coincidence data from NSIDC shows that the Arctic Sea Ice Maximum for 2022 was on 2/25/2022 the same day of the Antarctic new record minimum.
In the Arctic case this years max is just above the trend line for 2011-2020 so is well within the statistical noise of the recent past. It is higher, but not anywhere near a record high with satellite measurement showing 14,875,000 km^2 extent.

Using the same chart the all time Satellite extent record was set on 3/2/1979 and clocked in with 16,593,000 km^2 sea ice. At this point there is no significant down trend yet in evidence so guessing a minimum for 2022 would be pure speculation.
