By reviewing recent observational, numerical, and theoretical studies, progress in understanding the physics of climate change feedbacks is achieved as well as some of the reasons for the intermodel differences. Intermodel differences in cloud feedbacks have been confirmed as the primary source of climate-sensitivity uncertainty, and recent studies suggest that these differences stem primarily from the response of low-level clouds. New methodologies of model-data comparison and of decomposition of the global cloud feedbacks into dynamical and thermodynamical components should help to determine which of the model cloud feedbacks seem more reliable.
