Global warming drives growing number of Antarctic polynyas
Original: [Science News] # GlobalWarming is leading to the formation of an ever-increasing number of polynyas in # Antarctica . A
Scientists report that global warming is causing an ever-increasing number of polynyas to form in Antarctica. A polynya is a large hole in the sea ice, an area of open seawater surrounded by ice that in winter can reach a surface area roughly the size of Portugal. The trend is raising concern about accelerating ice loss in the region.
Why now: Rising concern about climate change impacts on Antarctic sea ice is drawing attention to these open-water gaps.
