Wonder if it's the sea ice melt that's pushed the Jet Stream further south
than normal this summer

There are still a few weeks of melting before the autumn freeze starts.


Any idea why the measurement of the area of ice is so different as that
at
NSIDC - 5.26? They both agree it's a record but can't agree on the value.
NSIDC tends to overestimate the amount of ice - it still shows ice in
Hudson Bay and Siberian rivers, for example - but I don't see this as
being
enough to account for the difference.

I can only think they are measuring different percentages of ice cover.
Do
you have a ready to hand link to what you are seeing at NSIDC, as I find
that site particularly hard to navigate?
