Weakened Atlantic overturning circulation may recover if global temperatures fall
New Scientist reports that achieving the modeled cooling through carbon removal would require more than current technology can deliver.
TLDR
New Scientist reports a climate model in which the Atlantic Meridional Overturning Circulation (AMOC) weakens under warming but starts to recover within decades of global cooling. Cooling by 0.2°C per decade through carbon removal would require 45 petagrams annually, equivalent to current total yearly emissions and beyond today's technological capacity. The model did not show a complete shutdown and may overestimate AMOC stability.
