“Rahmstorf, who has studied the Amoc for 35 years, has said a collapse must be avoided ‘at all costs.’ ‘I argued this when we thought the chance of an Amoc shutdown was maybe 5%, and even then we were saying that risk is too high, given the massive impacts. Now it looks like it’s more than 50%.’”

Critical Atlantic current significantly more likely to collapse than thought
Scientists say finding is ‘very concerning’ as collapse would be catastrophic for Europe, Africa and the Americas
The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding “very concerning” as a collapse would have catastrophic consequences for Europe, Africa and the Americas.
The Atlantic meridional overturning circulation (Amoc) is a major part of the global climate system and was already known to be at its weakest for 1,600 years as a result of the climate crisis. Scientists spotted warning signs of a tipping point in 2021 and know that the Amoc has collapsed in the Earth’s past. Continue reading...
