Multiple Cloud Feedbacks in a Global Model From a Single Perturbation Experiment

open access: yesGeophysical Research Letters
We document the wide range of global cloud feedbacks that can be obtained from a global model's single perturbation experiment. The wide range results from combinations of different options of producing cloud subgrid variability, interpreting the ...

How Does Plant CO2 Physiological Forcing Amplify Amazon Warming in CMIP6 Earth System Models?

open access: yesEarth's Future
The physiological response to increasing CO2 concentrations will lead to land surface warming through a redistribution of the energy balance. As the Amazon is one of the most plant‐rich regions, the increase in surface temperature, caused by plant CO2 ...

Cloud feedback overestimated in coupled CESM2 simulations relative to AMIP simulations and satellite observations: importance of the pattern effect and implications for climate sensitivity

open access: yesEnvironmental Research Letters
The community earth system model 2 (CESM2) has a high equilibrium climate sensitivity due to a large cloud feedback. Understanding whether its cloud feedback is realistic is thus of scientific and societal importance.

Enhanced shortwave absorption by water vapor increases effective climate sensitivity via accelerated AMOC recovery

open access: yesnpj Climate and Atmospheric Science
Climate models exhibit substantial inter-model spread in climate sensitivity, typically attributed to uncertainty in cloud feedbacks. In contrast, the influence of clear-sky shortwave absorption (SWA) remains underexplored, despite its substantial ...
