Influence of high-latitude atmospheric circulation changes on summertime Arctic sea ice

by Q. Ding et al., March 13, 2017, Nature Climate Change


The Arctic has seen rapid sea-ice decline in the past three decades, whilst warming at about twice the global average rate. Yet the relationship between Arctic warming and sea-ice loss is not well understood. Here, we present evidence that trends in summertime atmospheric circulation may have contributed as much as 60% to the September sea-ice extent decline since 1979.
