Achieving a sustainable climate may not be possible without well-considered intervention strategies, including Solar Radiation Management and Carbon Dioxide Removal strategies, coupled with aggressive mitigation, adaptation and restoration measures. This complex problem requires an integrated, unified response from a multitude of research communities. Following three successful sessions at the AGU Fall 2020 meeting (GC048, GC049 and GC039), we propose this as a continuing session for the Fall 2021 meeting. This session will continue the interdisciplinary effort by convening experts from the variety of fields involved in developing portfolios of climate intervention solutions and their consequences. We invite a range of abstracts on possible climate intervention strategies, interdisciplinary research design, scenario development for combined intervention strategies, Earth System and process modeling, including observational analogues, and assessments of ecological and societal impacts. We also invite papers that consider a pluralistic portfolio of solutions, discuss values-informed climate research, and the social sciences.
