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.

So what we are saying is that even with exceptional, and as Philip says
similar conditions to 2007 the ice trend is still according to the jaxa
data smack in the middle of the 2002-2008 levels. I see.

It has decreased by over 1,000,000 sq km in the last 12 days. *If it
keeps melting at that rate, in sixty days time it will reach 4,000,000
sq km, an all time low.

Cheers, Alastair.

But Alastair the melt rate isn't linear every recor has ups and downs as
opposed to a stedy delcline or rise. We still have July, August *and
September to go and that rate if weather conditions permitting could slow
thus. The gobal temps taken by the most accurate methods show notemperature
increse for the planet for nearlt ten years so how can the arctic ice melt
clang the death knell for our planet? Especially when the ice at the
opposite end is around record levels for 79-2008.

It's weather and as people like to keep saying weather isn't climate.

Lawrence,

Don't exaggerate. It's not the death knell for our planet, just
mankind.

Cheers, Alastair.
