On September 10, Antarctic sea ice likely reached its annual maximum extent of 16.96 million square kilometers (6.55 million square miles).
This is the lowest sea ice maximum in the 1979 to 2023 sea ice record by a wide margin.

Please note that this is a preliminary announcement. Changing winds or late-season growth could still increase the Antarctic ice extent.
NSIDC scientists will release a full analysis of the Antarctic and Arctic September conditions in early October.

blustnmtn,

Quite agree it is difficult to believe.
Notice that the image is still showing a net LOSS of ice in Greenland.
However, the mass balance seems to be heading towards a net GAIN

Carbon Brief shows a similar graph from 1986 to 2022

www.carbonbrief.org/guest-post-how-the-greenland-ice-sheet-fared-in-2022/

scroll down to "components of mass balance"
I have tried to include a copy of the Carbon Brief image but it doesn't seem to work.
Carbon brief explain that "The chart highlights that the only way for the ice sheet to gain ice is via the Snow Mass Balance – that is, through snowfall."

Strange? If you right click this placeholder and select 'Open image in a new tab', it seems to work. Why it doesn't display in the usual way is a mystery.

A reality check on arctic sea ice:

It will be no great surprise to see a similar situation evolve at the southern pole which certainly has a long periodic change in ice volume exceeding the satellite record and the dominant hysteria of our time. (Sorry for the long sentence 😵‍💫)
