Short summary

We show the results of transient simulations with a coupled climate–ice sheet model over the past 38 million years. The CO₂ forcing of the model is inversely obtained from a benthic δ¹⁸O stack. These simulations enable us to study the influence of ice sheet variability on climate change on long timescales. We find that ice sheet–climate interaction strongly enhances Earth system sensitivity and polar amplification.
