Arctic ice cover in decline
 
One site I regularly visit is that of Alastair McDonald. He has a page
(based on a NOAA site) that allows a comparison between now and four/eight
years ago, though other dates may be entered. This summer is showing a
very marked decline since four years ago, with virtually no ice on the
coasts of Siberia.

Here is the page:

Interesting site - I'll add that to my favourites. The
decline is quite marked but there seems little difference in the
maxima (Feb/Mar). This would seem to indicate that the ice is
shallower.

I returned to this site again today and the melting in less than two weeks
is amazing. You are quite right in suggesting the ice is thinner. The
colours clearly indicate that. Anyone doubting the existence of GW will
surely be convinced by this.

One thing I thought interesting was the 'increase' of ice down the
eastern side of Greenland. My personal explanation for this is that it
must be due to the position of the jet stream for most of this summer.
Normally the jet would take Atlantic depressions up there when, as we
all know, it has stayed south allowing a large pool of cold air to sit
in the region much of this summer.

Never underestimate the ability of GW-doubters to deny all evidence.

The following site shows that the decline is occurring in maxima as well as
minima. It's also accelerating.

which shows high pressure in the Greenland/Iceland region, and
a positive anomaly centre of +5mbar over eastern Greenland.

The ice east of Greenland is fed by ice from the Arctic Ocean moving SW in
the Greenland Current. Maybe that has been assisted by more northerlies
(or fewer SWlies) east of Greenland, associated with the anomaly you refer
to?

grr why do I keep typing Artic when I mean Arctic:-)

Isn't the ice being melted from below - by a warming Atlantic Ocean
feeding energy into the Arctic Ocean?

No. There is only one layer of ocean. Any further questions from you
along this line, will get the thought police out in vans. YOU HAVE
BEEN WARNED.
