The Arctic is rapidly losing sea ice, even during winter months, when temperatures are below freezing and ice should be recovering from the summer melt. Now, a new study in the journal Nature Climate Change has found that powerful storm systems called atmospheric rivers are partly responsible; the study finds they are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline.
“Arctic sea ice decline is among the most obvious eviden...
