Somethings completely different with this image. All the arctic SST
anomalies are negative (blue), the last few years we have been seeing
nothing but reds and yellows. Is something going on up there?

Looks a load of rubbish. How can they come up with a negative anomaly for an
ice-covered area which is normally ice-covered such as the Canadian Arctic?
They've either got a problem with their normals, their data, their program
logic, or the lot. The blue area in the Barents Sea, where it's ice-free
and normally ice-covered is almost as stupid. Perhaps they don't apply
values of -2C to ice-covered areas where they have no SST measurements.
