AMOC Could Weaken by 50% by 2100, French Study Warns
A new study published in the journal Science Advances by a French research team presents a concerning scenario regarding the Atlantic Meridional Overturning Circulation (AMOC). The research suggests that this critical ocean current system, which regulates global climate by redistributing heat from the tropics to the Northern Hemisphere, could weaken by up to 50 percent by the end of the century. This projection marks a significant upward revision compared to previous climate model estimates. The AMOC, often described as a marine conveyor belt including the Gulf Stream, transports vast amounts of warm surface water northward, where it cools and sinks. Its potential collapse or severe weakening is a subject of intense debate among climatologists due to its essential role in maintaining global temperature stability. The study highlights that the system, driven by water temperature and salinity, is facing stronger-than-expected disruptions. This finding underscores the urgent need to reassess climate risks associated with oceanic circulation changes, which could have profound impacts on weather patterns and ecosystems worldwide. The article emphasizes the scientific community's growing alarm over the accelerating slowdown of this vital planetary heat pump.
