Provisional Arctic Sea Ice Minimum

By Paul Homewood | Not A Lot Of People Know That | September 16, 2017

It’s now looking pretty certain that Arctic sea ice extent has passed its minimum this year. Since Tuesday, it has climbed over three days by 75,000 sq km, according to NSIDC figures:

2017 9 1 4.758
2017 9 2 4.791
2017 9 3 4.801
2017 9 4 4.782
2017 9 5 4.723
2017 9 6 4.643
2017 9 7 4.635
2017 9 8 4.697
2017 9 9 4.641
2017 9 10 4.628
2017 9 11 4.646
2017 9 12 4.611
2017 9 13 4.651
2017 9 14 4.651
2017 9 15 4.686

Provisionally that would make it the 4th highest since 2007.

The ice does not appear to be thin and slushy, as we are often told. According to DMI, much of it is 2 meters or more thick.

Pen Hadow’s abortive sailing expedition, now safely back in harbour in Nome, certainly ran up against unexpectedly thick and extensive ice 600 miles from the Pole, before being forced to turn tail.

It is far too soon to draw any conclusions about what this means for Arctic sea ice in future years.

But there is certainly nothing to support the wild claims of an Arctic death spiral, that we have been fed over the years.

The climate clown, Prof Peter Wadhams, seems to have kept his head down this year after his own succession of ludicrous claims, like this one last year.
