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.

It certainly fits in with the mean monthly sea-level pressure pattern
which shows high pressure in the Greenland/Iceland region, and
a positive anomaly centre of +5mbar over eastern Greenland.
(I'll provide a link in my synoptic review when I've uploaded the
relevant pages).

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:-)
