Policy Exchange: The US Can’t Go It Alone on Solar Geoengineering

"Smaller democracies should take a role in shaping solar geoengineering research and governance, say David Keith and Peter Irvine. Without them the challenges that solar geoengineering poses will be harder to tackle and the risks of mistrust and misuse will be greater."

SilverLining: The U.S. National Academy Of Sciences Report Recommends A Federal Research Program On Climate Intervention Strategies That Reflect Sunlight To Cool Earth: What Does It Mean?

"SilverLining is a longtime advocate for research on near-term climate risks and interventions to protect people and natural systems while society transitions to a sustainable future. For the past several years, we have been a driving force behind efforts to launch a U.S. National Academy of Sciences (NAS) study to develop an agenda and governance for research on climate interventions that increase the reflection of sunlight from the atmosphere to cool climate, or "solar climate intervention" (SCI)."

Advanced Science News: Does responsible climate leadership include research into solar geoengineering?

"Very little is known about the effects of solar geoengineering interventions, and many researchers agree that research as well as deployment should be carefully governed."

Lee, Walker Raymond; et al. (2021): High‐latitude stratospheric aerosol geoengineering can be more effective if injection is limited to spring

Lee, Walker Raymond; MacMartin, Douglas G.; Visioni, Daniele; Kravitz, Ben (2021): High‐latitude stratospheric aerosol geoengineering can be more effective if injection is limited to spring. In Geophysical Research Letters. DOI: 10.1029/2021GL092696.

"We demonstrate that spring injection produces approximately twice as much summer AOD as year‐round injection and restores approximately twice as much September sea ice, resulting in less increase in stratospheric sulfur burden, stratospheric heating, and stratospheric ozone depletion per unit of sea ice restored. We also find that differences in AOD between different seasonal injection strategies are small compared to the difference between annual and spring injection."

China Dialogue: Who should govern solar geoengineering?

"Solar geoengineering is increasingly being touted as a potential treatment for global warming, but its use also poses major risks to people around the world, especially if left ungoverned."

Zarnetske, Phoebe L.; et al. (2021): Potential ecological impacts of climate intervention by reflecting sunlight to cool Earth

Zarnetske, Phoebe L.; Gurevitch, Jessica; Franklin, Janet; Groffman, Peter M.; Harrison, Cheryl S.; Hellmann, Jessica J. et al. (2021): Potential ecological impacts of climate intervention by reflecting sunlight to cool Earth. In PNAS 118 (15), e1921854118. DOI: 10.1073/pnas.1921854118.

"We focus here on stratospheric aerosol intervention (SAI), a well-studied and relatively feasible SRM scheme that is likely to have a large impact on Earth’s surface temperature. We outline current gaps in knowledge about both helpful and harmful predicted effects of SAI on ecological systems."

Independent: Geoengineering atmosphere to reflect Sun’s heat ‘no better than shot in the dark’, scientists warn

"Research shows reductions in burning greenhouse gases, not attempts to reflect the sun, are the best way to mitigate the climate crisis, writes Harry Cockburn."
