Changing winds could amplify North Atlantic climate anomaly
June 04, 2025
As the planet's oceans are gradually warmed by the effects of climate change, a huge area in the North Atlantic stands out as an unusual zone of relative cooling. A region that stretches roughly from Greenland to Ireland, counterintuitively dubbed the North Atlantic warming hole, is a conspicuous patch of blue on global climate change maps. Researchers say its temperature contrast could intensify in the decades ahead as shifting climate-driven winds amplify the cooling process in the North Atlantic.
