Hi Albert, Thanks for finding that picture. Where did you find it?
The weakening is extremely worrying, considering the sun must still be low (<25 degrees?) at its noon elevation, north of 80 degrees latitude. I usually follow this report: http://nsidc.org/arcticseaicenews/ It is interesting to look at the temperature anomaly picture, which shows unusual cold over the Arctic. Presumably the trend of polar amplification continues by general warming of land mass and sea volume, while the air temperature fluctuates wildly. Is that right? Could it be the underlying sea temperature which is causing that weakening around the pole of inaccessibility, coupled with the sea ice being single-year perhaps? It is difficult to reconcile the weakening with a cold temperature anomaly. Could cloud cover be an important factor? When the air temperature is cold, there may be little cloud, so the sun gets through to melt the ice.
