This chart is a little ahead of the NSIDC one and you can see from it
that the Arctic sea ice has begun to melt again.

If the amount of Arctic sea ice is reducing in JANUARY, even if it turns
out to be only for a day or two, that seems remarkable and really brings
it home just how far global warming has gone.
It happened in 2012.

The sea ice etc. is chaotic, which makes it very difficult to predict.
It is very difficult to work out what it is going to do until it has
done it :-)
I can see that its chaotic nature would make it likely that in any
particular region it would reduce from time to time even in midwinter.
But it still seems remarkable to me that, taken over the Arctic as a
whole, the areas where the extent was reducing should be sufficient to
outweigh the areas where it was increasing, even for a brief period.
