Weird winds to blame for Greenland's huge water patch

Although last winter did see unusually warm temperature spikes in the Arctic, researchers say the cause for the big pool of open water in the middle of the ice—known as a polynya—was strong surface winds triggered by a dramatic warming in Earth’s upper atmosphere, known as a “sudden stratospheric warming.” The region normally has sea ice well into the spring.  https://www.futurity.org/greenland-winds-sea-ice-temperature-1942022-2/
