Worth noting some things about the melt season in the Arctic. The
season is characterised by acceleration and slowing down of the rate
of melt. The recent slowing down was probably due to some fairly
intense low pressures that had been affecting the Arctic Basin. These
storms can lead to a slowing of the melt and storms in August of 2006
were the reason why that summer didn't achieve a record low (2007 then
went on to stun all Arctic scientists, of course, with a quite
incredible ice low!).

As you can see from the wetterzentrale N. Hemisphere maps below, those
storms have been replaced by a large area of high pressure, which was
well forecast and has built over the last few days. It is presently
centred on the North Pole and is forecast to persist, drifting over
the Chuckchi Sea and the East Siberian Sea during the next week. The
increased insolation this will bring ought to kick start the melt in
the Arctic Basin and begin a rapid melt of the very vulnerable first-
year ice in the two other areas I've mentioned, as well as other
adjoining areas. Watch the rate of Arctic ice-loss over the next 7-10
days. I'd expect it to accelerate and we could well see a period of
very fast melt over the solstice and to the end of June.

Now let me get this straight: When it doesn't melt it's weather and when it
does its AGW LOL
