Arctic extent (cyan) is currently close to 2019, 2017, 2016, etc., but well above that of the record 2012. The next two weeks should see the minimum achieved, and barring any major fluctuation between now and then it's currently looking like it will similar to or slightly below 2019.

A few days from the annual minimum extent and this year is the lowest since the 2012 low benchmark. Unlikely to go lower than that record.

Interesting that it got this low after the bumper winter with much higher than recent years of ice cover.

After a delayed start the arctic temperatures have projected downwards rapidly in recent days - this bodes well for a sooner start to ice growth once more.

Today's ice figures are 3.59m Km2 which is the same extent as yesterday. [https://ads.nipr.ac.jp/vishop/#/extent]

Will we see an uptick in figures tomorrow? Or is there some further loss to be had?

Arctic sea ice extent minimum reached 3.55 million km2 on September 13th and has since commenced it's usual winter re-growth.

Yesterday, arctic sea ice gained a massive 105,000 km2 which is quite notable for a gain this size so soon after the minimum extent date. An average gain on this date would be roughly only 2,000 km2.

Here is the updated minima dataset including the 2020 value. The past decade has been relatively consistent with a linear trend of about -18,000 km² per annum.
