Climate Sensitivity and Feedbacks: Advances and New Paradigms

Session ID#: 281330

Session Description:
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 to have a very likely range of 2-5 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 responses to climate forcings, including pattern effects. We welcome submissions on theory, observations, and modelling studies including global climate models and high-resolution simulations of climate feedbacks, climate sensitivity, and climate responses of precipitation and large-scale dynamics. We especially encourage submissions that make use of long-term satellite observations and paleoclimate records, and explore new conceptual frameworks for thinking about processes that govern climate's response to external forcing.
