The National Science Foundation (NSF) awarded a $601,138 Project Grant under its Geosciences program (CFDA 47.050) to The Johns Hopkins University to conduct research on the nonlinearity and feedbacks in the atmospheric circulation response to increased carbon dioxide (CO2). The research aims to understand the mechanisms driving differences in circulation changes across climate models and the causes of nonlinear responses, such as the rapid weakening of the Atlantic Meridional Overturning Circulation (AMOC) and the CO2-induced changes in stratospheric ozone. The project will analyze model simulations and generate new simulations using the Community Earth System Model (CESM) and the GISS Model E2.2 to address these scientific questions. A sub-award of $23,357.61 was made to the University of Nevada, Reno to support the quantification of the nonlinearity in atmospheric response, the analysis of new CESM2 simulations, and the preparation of peer-reviewed publications. The research is expected to run from June 1, 2024, to May 31, 2027, and has been deemed worthy of support by the NSF based on its intellectual merit and broader societal impacts.
