On a previous post (here), I linked to a recent study positing that variations in Barents Sea ice extent are predictive of Arctic extent for at least 1-2 years later. In other words, they concluded based upon measurements of ice extent and ocean heat transfers: As winter ice extent goes in Barents Sea, so goes annual ice extent across the Arctic ocean. The physical cause is changing fluxes of warm North Atlantic water penetrating through the Barents Sea into the rest of the Arctic. They acknowledge that other factors, especially winds are also in play, but believe that the ocean influx (also affected by winds) makes the largest influence. The full study is here.

Here’s how researchers are connecting the dots:
NAO (North Atlantic Oscillation)► BSO(Heat transport by Atlantic Water (AW) through Barents Sea Opening)► Winter ice extent in Barents Sea► Winter ice extent…
