Atlantic current shutdown unlikely this century, study finds

A new study suggests that the collapse of Atlantic Ocean currents, which could drastically affect Europe's climate, is unlikely this century. Researchers used 34 computer models and found no total shutdown of the Atlantic Meridional Overturning Circulation (AMOC) before 2100. The study indicates that a second mechanism in the Southern Ocean may help maintain the AMOC, despite climate change. While the AMOC is expected to weaken, it is not predicted to stop completely, reducing the likelihood of extreme weather scenarios like a deep freeze in Europe. Current measurements show the AMOC is weakening, but definitions of a "shutdown" vary among scientists. Some models indicate significant weakening, which could still lead to serious climate impacts, even if the AMOC does not fully collapse.
