The Conversation: To meet the Paris climate goals, do we need to engineer the climate?
"Our read is that the Paris agreement will, through time, force closer consideration of so-called “climate engineering” or “geoengineering” schemes. In particular, we foresee increasing attention being paid to solar radiation management (SRM) or albedo modification technologies. This is a class of speculative responses that might cool the planet by reflecting some amount of solar energy back into space before it can trapped by the greenhouse gases in the atmosphere. Leading SRM proposals include depositing reflective sulfate particles into the stratosphere or increasing the reflectivity of marine clouds via the introduction of saltwater droplets."
