CopenhagenReviving a collapsed Atlantic current needs carbon removal matching all emissions.
A collapse would bring ice-age winters to Europe and disrupt monsoons in Africa and Asia.
A Danish Meteorological Institute model found the current strengthens within decades of removing carbon, but it is one model that may overstate stability.
“AMOC reversibility does not mean safety,” said Chuncheng Guo of the Danish Meteorological Institute.
Researchers in Germany are rerunning the experiment with 10 climate models to test the result.

- stresses that AMOC collapse may be reversible if cooling follows, testing the reverse-forcing case that earlier tipping studies skipped
