It seems possible, given the sort of year it has been. This plot from DMI shows what appears to be the classic “end of melt season” turn in sea ice extent, a good 2-3 weeks before it usually occurs. Whether this is just a wiggle that may be followed by a downturn remains to be seen, but it certainly is interesting.
JAXA reports a turn as well:
So does NANSEN:
If this is truly a turn in the melt season, it will be the earliest one in the satellite record and will mean that the average sea ice extent for September will be well above 6 million square kilometers.
That will put a real twist in the ARCUS sea-ice forecasting contest.
For those who would hold up the NSIDC chart and say “see, not turning!”:
I’ll point out that the NSIDC graph displays a 5 day running average, and like the Titanic, is slow to turn before collisions with near real-time data like we see with JAXA, NANSEN, and DMI.
This may be nothing more than a shift in wind pattern, changing sea ice concentration, only to shift pattern again in a few days, sending the curve downward again. But the air temperature is below freezing, according to DMI:
Mean Temperature above 80°N:
We will find out in a few days if this is really the end of melt season, or just a curious blip. Watch the WUWT sea ice page.
