Notwithstanding data errors - which could always be the case and will
only come out in the wash, there has been an exceptional acceleration
of melting in the Arctic over the last few days. The ijis figures show
that over 40,000km2 of ice was lost in 3 days from 2nd to 5th July. I
can't see an ice loss of that magnitude, in that short a timespan,
anywhere in the sequence. The ice loss will show on the various sites'
graphs shortly, I would think.

I think it is more likely to be down to synoptics rather than anything
else, but it is interesting, nevertheless. Parts of the Arctic have
some very warm uppers at the moment and a large area of high pressure
is stretched across the North pole, more than likely giving strong
sunshine (for the Arctic, albeit with a low sun, of course) 24 hours a
day.
