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)."

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."

The Conversation: Solar geoengineering is worth studying but not a substitute for cutting emissions, study finds

"Solar geoengineering strategies are very controversial within and beyond the climate science community. It is a major step forward to have 16 experts from different disciplines agree that now is the time to establish a research program on this topic."
