Title
ECS > 5 K; a tale of two models

Abstract
E3SMv1 and CESM2 are close cousins. Perhaps not surprisingly, both models share a high climate sensitivity (ECS > 5 K). Despite this similarity, these two models behave differently in idealized CO2 forcing simulations (abrupt-4xCO2, 1pctCO2) as well as historical simulations. In particular, we explore possible reasons why one model (CESM2) simulates the evolution of the global mean surface temperature over the historical record significantly more accurately than the other (E3SMv1).
