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.

A vast opening in Antarctic sea ice, roughly the size of Portugal, has drawn scientific attention, with researchers pointing to climate change as a likely driver. The phenomenon, known as a polynya, is prompting discussion about warming oceans, shifting winds and what the hole reveals about changes underway in the Southern Ocean around Antarctica.

A massive open-water hole, or polynya, nearly the size of Portugal opened in Antarctica's winter sea ice, and scientists now say they understand its cause. Researchers point to a combination of ocean circulation and storm activity lifting warm deep water to the surface, keeping the area ice-free even in freezing conditions.
