National Academies of Sciences, Engineering, and Medicine (2021): Reflecting Sunlight: Recommendations for Solar Geoengineering Research and Research Governance

National Academies of Sciences, Engineering, and Medicine (2021): Reflecting Sunlight: Recommendations for Solar Geoengineering Research and Research Governance. Washington, DC: The National Academies Press. https://doi.org/10.17226/25762.

"While efforts to reduce emissions and adapt to climate impacts are the first line of defense, researchers are exploring other options to reduce warming. Solar geoengineering strategies are designed to cool Earth either by adding small reflective particles to the upper atmosphere, by increasing reflective cloud cover in the lower atmosphere, or by thinning high-altitude clouds that can absorb heat. While such strategies have the potential to reduce global temperatures, they could also introduce an array of unknown or negative consequences."

C2G Guest Post: Stratospheric aerosol injection could be a painkiller, but not a cure – and more research is needed

"It has to be clear that at best SAI would be a complement to emission reductions, which have to be the absolute priority, and probably carbon dioxide removal. SAI could reduce climate change impacts, but it would not contribute to the ‘solution’."
