A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid\u002Dcentury, according to a new study, and scientists…
In recent decades, researchers have both raised and downplayed the specter of Atlantic current collapse. It even prompted a movie that strayed far from the science. Two years ago the United Nations Intergovernmental Panel on Climate Change said any such catastrophe is unlikely this century. But the new study published in Nature Communications suggests it might not be as far away and unlikely as mainstream science says.
In the new study, Peter and Susanne Ditlevsen, two researchers from Denmark, analyzed sea surface temperatures in the North Atlantic between 1870 and 2020 as a proxy, meaning a way of assessing, this circulation. They found the system could collapse as soon as 2025 and as late as 2095, given current global greenhouse gas emissions. This diverges from the prediction made by the Intergovernmental Panel of Climate Change in 2021, which said the collapse isn’t likely to occur this century.
