Stratospheric Aerosol Injection

What is Stratospheric Aerosol Injection?

Stratospheric aerosol injection is a solar radiation management (srm) geoengineering or climate engineering approach that uses tiny reflective particles or aerosols to reflect sunlight into space in order to cool the planet and reverse or stop Global Warming. The approach involves spraying reflective sulfate aerosol particles into the stratosphere with high altitude airplanes, tethered balloons, high-altitude blimps or artillery.

Stratosphere definition

The stratosphere (see NOAA image below) is a layer of the Earth’s atmosphere that ranges between 7 to 31 miles above the ground between the Troposphere and the Mesophere. The stratosphere is an ideal target for atmospheric geoengineering because it is relatively isolated from human populations, is accessible by planes (and other transport/delivery methods), and doesn’t have weather such as rain that would cause aerosol spray particles to fall quickly to the ground.
