Detailed report on the use of solar geoengineering

A San Francisco nonprofit called Reflective has released a detailed road map outlining the research, experiments, and infrastructure needed to make informed decisions about stratospheric aerosol injection (SAI), a proposed solar geoengineering technique involving releasing reflective particles into the stratosphere to combat climate change. The coordinated research effort could take about a decade and cost $370 million, though it would take longer and cost significantly more if uncoordinated. However, the proposal remains controversial, with hundreds of academics calling for a ban on outdoor experiments and raising fundamental questions about who would control such a planet-altering technology.
