The Atlantic Ocean can handle more warming than expected — with one big catch
New research suggests that the stability of the Atlantic Meridional Overturning Circulation (AMOC) depends more on the speed of global warming than on a fixed temperature threshold. This indicates that rapid climate change could trigger a collapse even if total warming remains lower than previously feared.
Why it matters
The AMOC is critical for regulating global climate; understanding its tipping points is essential for accurate climate change projections.
For years, climate scientists have warned that the Atlantic Meridional Overturning Circulation (AMOC) could eventually shut down if global temperatures rise too far. New findings from researchers at Utrecht University suggest that temperature alone does not determine the fate of this major ocean circulation system. The speed at which the planet warms also appears to play a critical role in whether the AMOC remains stable. The study was published in the scientific journal Nature Climate Change.
The Atlantic Meridional Overturning Circulation, or AMOC, is a vast network of ocean currents that carries warm water northward from the tropics. By moving heat around the planet, it strongly influences the global climate and helps maintain the relatively mild conditions found in Western Europe.
