PIOMAS shows that Arctic ice has gained only 25 cm (10 inches) thickness since October. That number is absurd, after four months of temperatures far below freezing. Particularly since essentially all of the new ice is greater than 50 cm thick.
I derived these numbers by dividing PIOMAS volume by UIUC ice area.
Is there anyone who can calculate how thick the ice would be if we had the same temperature but no wind and no moving water? The ice is insulating the sea water from the cold air .

My favorite ice fishing hole has 18″ of ice and has been frozen for 6 weeks. I know it has not been as cold as the arctic.
Ahh but the warmanistas tell us that the new GLO-BULL warming ice is rotten … so rotten it can melt at temperatures below freezing 😉
