a Spatial distribution of temperature difference resulting from baseline CO2 level (450 ppm) above pre-industrial condition, calculated as the temperature difference between the baseline equilibrium state and the pre-industrial temperature. c Temperature change due to AMOC collapse at 450 ppm (ΔTAMOC), determined by subtracting the baseline equilibrium temperatures from the final state after AMOC collapse. e Total temperature response to the AMOC collapse at 450 ppm baseline experiment, calculated as the difference between the final equilibrium state after AMOC collapse and the pre-industrial state. Changes in mean surface air temperature due to AMOC collapse for the full coupled model setup under various baseline CO2 levels during hosing experiments (computed as the difference from each experiment’s initial value): (b) global mean surface air temperature anomaly (ΔGMTAMOC), (d) mean surface temperature change over 60∘N − 90∘ N, and (f) mean surface temperature change over 60∘S − 90∘S.
