This work package aims to identify and evaluate observable quantities that govern transient climate response (TCR), the standard measure of transient climate sensitivity (TCS) in earth system models. In this regard, we will move towards a new paradigm in which the model-derived range of plausible TCR values is increasingly based on models that are sound with respect to these key observables.
