Finding the right "dose" for solar geoengineering
One of the key misconceptions about solar geoengineering — putting aerosols into the atmosphere to reflect sunlight and reduce global warming — is that it could be used as a fix-all to reverse global
Solar geoengineering seems like the crackbrained scheme of a mad scientist, and cannot solve climate change without massive reduction in CO2 emissions. But my colleague David Keith shows that moderate amounts could help, and without adverse local effects.
New research in
shows that solar geoengineering could halve global temperature increases without making climate change worse
