A major goal of current climate research is to reduce uncertainty in metrics of large-scale forced climate responses, such as the Equilibrium Climate Sensitivity (ECS), the eventual warming in response to doubled atmospheric CO2. The ECS is estimated at 1.5—4.5 K, a range largely due to clouds and other moist processes. These processes are deeply intertwined and are linked to changes in societally important factors such as precipitation. This session explores recent advances in understanding large-scale climate response to climate forcings. We welcome submissions on theory, observations and modelling studies of climate feedbacks, climate sensitivity, and climate responses of precipitation and large-scale dynamics, especially those exploring novel evaluation techniques such as emergent constraints, and new ways of thinking about processes that govern climate's response to external forcing.
