The autumn freeze is under way in the Arctic and
analysis of the summer melt is getting under way. You'll recall that the ice
area didn't beat 2007's startling minimum, coming a mere second-worst-since-humans-evolved.
Yay.
It's not all roses though (if that qualifies as roses, and frankly, if that does qualify as roses then I want what you're taking).
This NSIDC map shows the ice age at the melt minimum. Red is first-year ice, stuff that froze in the winter of 2007-8. Orange is two-year ice, yellow is three years or older (white is where there isn't enough ice to tell - patchy, grobbly stuff the satellite can't get a bead on).
The North Pole is just about where the old ice that's shoved up against Greenland ends and the one-year ice in the middle of the 2008 picture begins.
New ice is thin, old ice is thick. So while the
area isn't less, the
volume of ice in the Arctic is less: like the NSIDC boffins say, "no recovery at all" and it "strongly reinforces the downward trend".
