This strange spot in the Atlantic is resisting global warming. Scientists think they know why.

August 7, 2017

mysterious “warming hole” in the North Atlantic Ocean, an anomalous zone of cooling temperatures which has fascinated and puzzled scientists for the past few years, may be evidence of more troubling processes at work.

new study, just out in the journal Nature Climate Change, has joined a growing body of literature suggesting the cold patch is evidence that a major ocean current system — which transports heat and influences climate and weather patterns around the world — may be slowing down. What’s more, the melting of Arctic sea ice could be to blame.

“I think the main thing about our paper that we show is that the Arctic sea ice loss can play an active role in climate change and ocean change as well,” said Alexey Fedorov, an ocean and geophysics expert at Yale University and one of the new study’s authors.
