This paper briefly describes the basic configuration and experimental design of the CAS-ESM2.0 for G1ext, which involves a sudden reduction in solar irradiance to counterbalance the radiative forcing of an abrupt quadrupling of atmospheric CO2 concentration, running for 100 years. Preliminary results show that this model can reproduce well the compensatory effect of a uniform decrease in global solar radiation on the radiative forcing resulting from an abrupt quadrupling of CO2 concentration. Like other Earth system models, CAS-ESM2.0 reasonably captures variations in radiative adjustments, surface air temperature, and precipitation patterns, both globally and locally, under the G1ext scenario. The generated datasets have been released on the Earth System Grid Federation data server, providing insight into the potential efficacy and impact of solar geoengineering strategies. *Source: Springer Nature Link * -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
