One of the most controversial forms of geoengineering is solar radiation management (SRM), which aims to reduce the amount of sunlight reaching the Earth’s surface by reflecting or scattering some of it back to space. SRM could involve spraying aerosols into the stratosphere, creating artificial clouds over the oceans, or launching mirrors or reflectors into orbit.

While SRM might seem like a quick and cheap way to cool the planet, it also poses many risks and uncertainties. For instance, SRM could have unintended consequences that range from damaging…
