It’s that time of the year again!
Unfortunately Peter Wadhams is wrong yet again:

Ice extent is a bit lower than recent years this September, but it is still well above both 2007 and 2012.
DMI, of course, like to show a highly misleading graph, showing an ongoing declining trend, along with cut off y-axis.
In reality however, the decline stopped in 2007, and there has been no trend since, merely year to year variation.

Is the choice of 2007 a cherry pick? Not really, because a lot of the thick multi-year ice was swept out through the Fram strait in that and the following year. Subsequently the thinner ice replacing it has been more prone to melt.
In other words, 2007 cannot be statistically regarded as an outlier, but integrally connected to following years.
As we can see, temperatures around the Arctic have been normal all summer:

Sea ice is also thicker this year than in 2008 across the central Arctic. Most of the thickest ice then was off the north coast of Greenland, soon to be swept away.

All the indicators therefore suggest that Arctic sea ice extent is currently stable..
Meanwhile, down under Antarctic sea ice extent has been very close to average during September, when it is at its highest:
