Scientists say there is a high chance that key Atlantic Ocean currents will weaken over the coming decades due to climate change — but whether they have already slowed is hotly debated. Now, a new study finds that Atlantic circulation has remained stable since the 1960s, suggesting the system may be more resilient to warming than scientists thought.
But the results are controversial. Previous studies show mixed results, with some papers concluding that the Atlantic Meridional Overturning Circulation (AMOC) is weaker now than at any point in the past millennium, and others finding little to no evidence for a decline in current strength.
