Solar radiation management (SRM) could quickly offset global warming caused by anthropogenic greenhouse gas emissions. Because SRM would have global side effects, it raises not only technological but also political and social concerns. Therefore, SRM research should be accompanied by a global...

Solar geoengineering appears able to reduce climate-change risks but raises controversy, the leading cause of which is the concern that its research, development, or use might inappropriately obstruct efforts to cut greenhouse-gas emissions (“mitigation”). Describing how policies could...

Solar geoengineering (SGE) can combat climate change by directly reducing temperatures. Both SGE and the climate itself are surrounded by great uncertainties. Implementing SGE affects learning about these uncertainties. We model endogenous learning over two uncertainties: the sensitivity of...
