The study, published in Science Advances, underscores the potential for severe global impacts, including shifts in tropical rain belts and harsher European winters. While the decline's direct link to human-induced climate change remains unconfirmed, the weakening trend poses significant risks to global weather patterns and sea levels. The consequences of a weaker AMOC extend beyond sea-level rise, affecting marine ecosystems and disrupting food chains. Coastal communities are particularly vulnerable due to increased flooding and erosion.
