Rapid Warming Could Tip the AMOC at Just 2°C — Slow the Pace and It May Survive Beyond 5°C

A recent modeling study finds that the Atlantic Meridional Overturning Circulation (AMOC) has no fixed global-temperature tipping threshold; its stability depends strongly on the rate of warming. Rapid CO₂-driven warming (near today’s pace) can trigger collapse near ~2°C above pre-industrial levels, while much slower warming can keep it stable well past 5°C.
