Alarmists claim that, due to anthropogenic climate change (AGW), the Atlantic Meridional Overturning Circulation (AMOC) is weakening to the point that it’s on the verge of collapsing. It’s claimed this will lead to abrupt cooling and extreme weather in the North Atlantic region.

But the author of a new study points out that changes in sea level trends are a useful proxy for detecting AMOC variability over time.

Interestingly, from one side of the Atlantic to the other, or, specifically, from the coasts of New York to the coasts of France, mean sea level rise has been stable, not accelerating, since 1960.

This affirms the stability of the AMOC and contradicts the narrative that the AMOC is on the cusp of collapse.

“…a negligible difference in absolute sea level rise between these locations [The Battery, New York, and Brest, France] reinforces the stability of the AMOC within the period 1960 to 2024. These findings challenge claims of AMOC weakening.”
