I'm sure you're right. Until very recently the NCODA chart had all the ice
area "blanked out", ie it only showed the greenish colour for no anomaly.
Now, large areas of ice covered sea are showing dark blue. That would be OK
if this indicated ice that should have melted by now, but I suspect actually
we are no longer comparing "like with like".

A better tell-tale is surely the the fringe of bright red and orange colours
where open water several degrees above the nominal -2C for freezing seawater
is present where climatologically ice should be. From the ice concentration
images, it looks like the NE passage will very soon be open, and the NW
passage is also thawing quickly. And, once again, the Labrador Current has
been partly cut off and sea surface temperatures around Nova Scotia are
several degrees above normal.

I suspect another low sea-ice year is in prospect, especially after reports
that some fjords in Svalbard (Spitzbergen) which normally freeze over at
least partially have remained open this last winter.
