Because the incoming and the outgoing flows, warm and cold respectively, lie side ‐ by ‐ side between Greenland and Scandinavia, an asymmetry is induced in the distribution of ice - cover on the Arctic Ocean; this is generally dense to the west of Fram Strait while, to the east of Spitzbergen, much of the Barents Sea — at similar latitudes — remains ice ‐ free even in winter due the eastward flow of warm Atlantic water.

The point to be made regarding that paper is similar to the one I made above: there is evidence that internal variability (to the extent it can be equated with the AMO) has affected the rate at which anthropogenic forcing has warmed the surface, but most of the warming must have been forced, with the observed positive ocean heat uptake data excluding more than a very minor role for internal variability in the warming itself with very high confidence.
