The Atlantic Meridional Overturning Circulation (AMOC) is at its weakest in 1,600 years, posing an imminent threat due to climate change. Recent studies show a 70% chance of collapse if carbon emissions continue rising, with serious repercussions for global weather patterns and sea levels. The AMOC acts as a critical climate regulator, transporting warm water from tropics to the North Atlantic, crucial for maintaining milder conditions in Europe.
Research indicates that potential turning points for AMOC shutdown could arise in the next few decades, with the actual collapse occurring 50-100 years later. The study highlights a need for urgent reduction in greenhouse gas emissions to avoid irreversible damage. Consequences of the collapse would include drastic shifts in precipitation patterns, disruption of agriculture, extreme weather in Europe, and rising sea levels, threatening coastal communities and ecosystems.
The findings stress the urgency for immediate global action to reduce carbon footprints, as even a 10% risk of AMOC failure is deemed unacceptable. Ongoing observations and model predictions indicate a shrinking window for effective action against climate disruption.
