Abstract Recent studies show that global mean surface temperature exhibits a transient hysteresis during CO2 ${mathrm{C}mathrm{O} }{2}$ removal, where temperatures remain elevated after CO2 ${mathrm{C}mathrm{O} }{2}$ concentrations return to pre‐industrial levels. This is largely attributed to ocean thermal inertia rather than an irreversible climate response; however, the role of radiative feedbacks remains unclear. Here, using a fully coupled Earth System Model, we find that radiative feedbacks are nearly identical for CO2 ${mathrm{C}mathrm{O} }{2}$ increase and subsequent removal up to 3 times pre‐industrial CO2 ${mathrm{C}mathrm{O} }{2}$ concentrations. However, at 4× CO2 ${mathrm{C}mathrm{O} }{2}$ and higher forcings, feedbacks become more stabilizing during CO2 ${mathrm{C}mathrm{O} }{2}$ removal. Through a hierarchy of experiments we show that this is driven by low‐level clouds in the North Atlantic, linked to warmer sea‐surface temperatures from an overshoot of Atlantic Meridional Overturning Circulation (AMOC) strength during CO2 ${mathrm{C}mathrm{O} }{2}$ removal. These results suggest that AMOC‐mediated feedbacks contribute to the transient temperature hysteresis in future CO2 ${mathrm{C}mathrm{O} }{2}$ removal scenarios by keeping the removal phase warmer.
