Russotto, Rick D.; Ackerman, Thomas P. (2018): Changes in clouds and thermodynamics under solar geoengineering and implications for required solar reduction. In Atmos. Chem. Phys. Discuss., pp. 1–32. DOI: 10.5194/acp-2018-345.

"The amount of solar constant reduction required to offset the global warming from an increase in atmospheric CO2 concentration is an interesting question with implications for assessing the feasibility of solar geoengineering scenarios and for improving our theoretical understanding of Earth's climate response to greenhouse gas and solar forcings. This study investigates this question by analyzing the results of 11 coupled atmosphere-ocean global climate models running Experiment G1 of the Geoengineering Model Intercomparison Project, in which CO2 concentrations are abruptly quadrupled and the solar constant is simultaneously reduced by an amount tuned to maintain top of atmosphere energy balance and preindustrial global mean temperature."
