And since the NSIDC's update on the 6th Feb, Arctic Sea ice has decreased and a very early melt appears to have started in the Barents and in the Bering seas. The Kara sea is already losing ice too. The western coast of Svarlbad appears to be almost free of ice. Could Arctic Sea ice have actually peaked in the first week of Feb? I very much doubt that, but nothing like the low current ice extent has ever been observed before. Warm times in what should be a cold Arctic.

Unlikely to be the start of the Spring melt, as the Polar night still continues. The melt must be due to anomolous airflow into the region, and there is likely to be a counterbalancing freeze occuring elsewhere.

It's due to anomalously high temperatures, for sure. The NSIDC update pointed to that, but the spring melt begins when the peak freezing has been reached. There is no counterbalancing freeze in the Arctic margins, as yet - though I accept it is likely, still.

As I say, I doubt peak ice has happened, but it's only about 4 weeks until the peak ice average date. A cooling will have to happen for the graph line to rise again. I think it is likely, but it has to happen.

For followers of this sort of thing. At current trends, then in about 3
days time, the global Arctic+Antarctic summed sea-ice extent on-this-day
record will be under-exceeded or whatever the term is.

It is interesting to note that the record Arctic Ice low, recorded in 2012, was preceded, in April, by a much higher extent that now. Indeed, it was at the 1981-2010 Median (we are well outside the -2SD range currently).

Whereas last year, which was nowhere near a record, ice extent was pretty much the same last April as it is currently.

As I say every year; a new record Arctic ice extent low will come and will be succeeded by many more over the years, but in an individual year, the spring ice extent has little influence. The September low is mainly down to the weather over the melt period.

I can no longer access the number data, Charctic site, but it looks like
another on-this-day record low Antarctic + Arctic global sea-ice extent from

Default [CC] Global Sea Ice at record low

30 April 2018, record lowest ever global (Arctic+Antarctic) sea-ice
extent on this 30th day of April of any year of the satellite era (NSIDC
algorithm), less than 2017 and less than 1980.
30 April 2017 20.366 million sq km
30 April 2018 20.341 million sq km

Default [CC] Global Sea Ice at record low

From Charctic NSIDC
Record low on any 08 Sep of the satellite era , for Artctic + Antarctic
sea-ice.
Previous record was 2017 at 22,630 sq km
08 Sep 2018 was 22,584 sq km

So is this global metric racing away?
For 12 Sep 2017 22.707 x10^6 sq km arctic+antarctic, via Charctic
2018 22.326
so 381,000 sq km less this 12 Sep than any 12 Sep of the satellite record
