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.
If it is reducing in January, surely that isn't directly related to the
temperature, it should be well below freezing up there now. It is not
something to do with the synoptics, maybe storminess leading to breakup
and advection of sea ice (I haven't checked this out so am just
speculating)?
