Atlantic Current Collapse Risk Now Elevated, Study Confirms
Recent research indicates that the collapse of the Atlantic meridional overturning circulation (Amoc) is no longer a low-likelihood event, potentially occurring within decades. The study analyzed climate models extending to the years 2300 and 2500, revealing that under high-emission scenarios, Amoc collapse occurred in 70% of the models. Even with low emissions, a shutdown was still seen in 25% of the models, underscoring the urgency of reducing fossil fuel emissions. The researchers found that the tipping point where an Amoc shutdown becomes inevitable is likely to be passed in the next 10 to 20 years.
