New research reveals a potential drastic temperature drop in northern Europe if the Atlantic Meridional Overturning Circulation (AMOC) collapses. Even with global warming, a weakened AMOC could lead to significantly colder winters, with London potentially experiencing -20°C and Oslo -48°C. The study, using climate models, explores scenarios where AMOC collapses under varying levels of warming. While acknowledging model limitations, researchers highlight the need for societal adaptation to such extreme cold, emphasizing the potential for dramatic temperature swings and increased winter storms.
