Sunlight reflection methods

Sunlight reflection methods (SRM) are hypothetical approaches to lower global temperatures by increasing the amount of sunlight reflected to space.

Sunlight

Stratospheric aerosol

injection (SAI)

Tiny particles released in the stratosphere would directly reflect a small fraction of sunlight.

Marine cloud brightening (MCB)

Sea salt particles would be sprayed from ships to enhance the reflectivity of low-lying clouds
