Atlantic Ocean currents can recover from severe climate weakening, study finds
The study found the current could regain strength if temperatures fall, but warned recovery may take centuries and Greenland melt could still raise seas.
- On Wednesday, a new study by the Danish Meteorological Institute showed the Atlantic Meridional Overturning Circulation could recover if global warming reverses, finding no irreversible tipping point for the current system.
- The AMOC brings warm water from the tropics toward the Arctic, keeping Europe's winters mild; global warming weakens this flow, yet the study indicates it may regain strength if temperatures eventually fall.
- Modeling the AMOC's slowdown, researchers estimated a drop from around 17 million to about 6 million cubic metres of water per second at around 7 degrees Celsius of warming; lead author Chuncheng Guo warned recovery could take several centuries.
- Greenland's ice sheet, which contributes to weakening by pouring cold freshwater into the ocean, cannot be restored even if warming reverses; a disrupted AMOC could destabilize global rainfall patterns and accelerate coastal sea-level rise.
- Climate researchers warn global temperatures may exceed the 1.5 Celsius threshold "within a few years"; Willem Huiskamp at the Potsdam Institute for Climate Impact Research questioned the model's stability, while Guo emphasized that preventing warming is a "much, much safer strategy.
