You're a very naughty boy! ;-)

Seriously, though, this doesn't look much like weather:

Interests me that the graph for spring has declined faster than the
winter one.

Also, the volume of sea-ice has been below 2007 all year:

I know - but the snapshots are almost enough for a video now ;-))

Still optimistic that this somewhat unusual autumn pattern is the
harbinger of some really cool stuff to come. After all slush and muck in
November has never been proved wrong has it....

That's a shocking decrease indeed!

I've got to ask, about a post concerning Arctic ice cover in mid-
November.........so???

I hope you say that when Larry tries again to give us his snapshots -
but you've never done it before, so I can't see you starting now Will!

I was surprised to read in the book I got on the USS Skate's polar
adventures that, in 1958, scientists were investigating the reported
warming of the Arctic and thinning of the ice cover. But then, I suppose
the 0.3C warming in the first part of the last century must have had
some effect, presumably on ice thickness, though nothing much shows
up on the graphs of ice-extent until the fifties.

Cheers, Alastair.

Arctic ROOS is a shorter data set, has different data sources, often
deviates from NSIDC/Cryosphere and the temporarily (permanently)
defunct IJIS data. I wouldn't use it as a benchmark. I'd stick to
NSIDC/Cryosphere to make comparisons to past years and for quite a few
years yet. You can see the pretty wild variations in Arctic ROOS' data
from your graph.

in addition, (not you Alastair, I know you were just poining to a
different dataset) commenting (on ice cover in the middle of the
freeze, or melt season when it deviates from other years really is
like telling us about the weather. These unusual deviations do occur
and April 2010, when ice cover melted much more slowly than usual. was
a classic example and got Watts and other deniers salivating. It's
almost certainly down to synoptics, or possibly warmer water and it is
highly likely to return to it's recent pattern soon. James has done a
Larry/April 2010 here.
