Solar geoengineering has the potential to reduce global warming, but with uneven regional impacts on temperature, precipitation, and other climate variables. We will use climate modeling to evaluate various proposed geoengineering schemes using both the generation of stratospheric aerosol clouds and the brightening of marine boundary layer clouds, in terms of their impacts on agriculture and ecosystems. We will investigate whether certain combinations of stratospheric and marine geoengineering can reduce negative regional impacts. And we will examine adaptation strategies to minimize the negative impacts of geoengineering.
