Why geoengineering is not a solution to the climate problem

This briefing addresses grave scientific concerns in relation to proposed geoengineering techniques such as solar radiation management (SRM). “Geoengineering” as used here does not refer to negative emissions technologies that remove CO2 from the atmosphere (carbon dioxide removal or CDR) as part of the energy system or through ecosystem restoration and afforestation or reforestation. Here we specifically address the risks posed by SRM.
