September Arctic Sea Ice Trends

by P. Homewood, Oct 8, 2022 in NotaLotofPeopleKnowThat


We looked at the Arctic sea ice minimum for this year a couple of weeks ago. But the average for September as a whole is much more relevant.

In fact it shows very similar results this year, with average September extent slightly below last year, but otherwise the highest since 2014, and also much greater than in 2007:

Note the grossly misleading trend line, loved by all Arctic alarmists! Their trend cannot conceal the fact that the ice extent stopped declining in 2007.

The ice could remain stable for the next century, but DMI’s overall trend line would still show a long term decline decline.
