A significant decline in the AMOC could lead to drastic changes in global weather patterns, including cooling in the Northern Hemisphere and shifts in rainfall. These changes would directly impact agriculture, with global yields of staple crops like wheat, maize, and rice potentially decreasing by an average of 5.3%. However, the effects would vary by region, with some areas experiencing much sharper declines. For instance, countries like Germany and Ukraine could see cereal yields drop by up to 19%, while Canada might face a 12% reduction.
