Short summary
Using Earth system model simulations, we show that carbon cycle feedbacks are asymmetric under positive and negative CO2 emissions due to non-linear responses to CO2 and temperature change, and asymmetric ocean circulation changes. These asymmetries propagate onto the asymmetry in the transient climate response to cumulative emissions. Our work emphasizes the need to evaluate climate and carbon metrics under negative emissions rather than applying metrics from positive emissions scenarios.
