Over the past 10 days, the rate of sea ice extent loss in the Arctic has slowed down somewhat. And as a result sea ice extent measures, though maintaining in record low ranges, are much closer now to the 2012 line. Low pressure systems have come to dominate the Arctic Ocean zone. And the outwardly expanding counter-clockwise winds from these systems have tended to cause the ice to spread out and to thin. In the past, such events were seen as an ice preserving feature.
