It is unusual wind conditions expanding ice extents into the Bering Sea.
The Arctic Ice freezes from the top, and melts from the bottom. Right now it is still below the freezing point of sea water in the far north. The wind is pushing pack ice from the north south into the Bering Sea (where it is melting). New ice is freezing in the colder northern regions where the pack ice came from giving the appearance of an increase in ice extent (in the sense of winter record keeping).
The new ice is thin, and will melt quickly this summer. There is no ice volume to accompany this late season increase in ice extent.
The total amount of Arctic ice is declining. Observation satellites are simply noting that the ice is thinner spread over a larger area.
