Climate Sensitivity and Feedback Factors

This lecture covers the concept of climate sensitivity, focusing on the equilibrium climate sensitivity (ECS) and the feedback factors influencing it. It discusses the role of various feedback mechanisms such as cloud feedback, water vapor feedback, and lapse rate feedback in determining the Earth's response to radiative forcing, as well as the evolution of climate models in estimating ECS. The lecture also explores how emergent constraints and paleoclimate records are used to constrain ECS estimates and reduce uncertainties in climate projections.
