ATLANTIC OCEAN CURRENT TO REMAIN SAFE

The Atlantic meridional overturning circulation, commonly referred to as the “AMOC,” is a system of ocean currents confined to the Atlantic basin that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to the Northern Hemisphere, says Caltech @ Eurekalert.

The AMOC also modulates regional weather, from the mild summers in Europe to the monsoon seasons in Africa and India. Climate models have long predicted that global warming will cause the AMOC to weaken, with some projecting substantial weakening amounting to a near-collapse relative to the AMOC’s strength today.

Such a weakening would have far-reaching consequences, including changes in regional sea level rise and major shifts in regional climate, such as colder conditions in northern Europe and drier weather in parts of the Amazon and West Africa.

However, a new study from Caltech finds that although the AMOC will weaken under global warming, it is likely to do so to a much lesser extent than current projections suggest.
