Satellite observations provide some of the strongest evidence yet that the Atlantic Meridional Overturning Circulation is slowing. An analysis of how much heat the ocean releases to the atmosphere indicates the crucial current system, which carries warmth toward Europe, has weakened by about 18% over the past 40 years. The finding adds to growing concern that a major ocean circulation could be approaching a tipping point, with significant implications for European climate.

Attention is turning to the Atlantic Meridional Overturning Circulation, the system of ocean currents that includes the Gulf Stream and helps regulate the climate of Europe and North America. The UK House of Commons Library has published an overview asking whether the circulation is weakening, summarising the science behind concerns that freshwater from melting ice could slow it down, with potential consequences for weather patterns and sea levels.

New analysis based on satellite observations provides some of the strongest evidence so far that the Atlantic Meridional Overturning Circulation, the ocean current system that helps regulate the climate of Europe and North America, is weakening. Scientists warn that a significant slowdown could alter weather patterns, raise sea levels on the US east coast and disrupt rainfall, though the pace of any decline remains debated.
