"Is Stratospheric Aerosol Injection Currently Feasible?

"Stratospheric Aerosol Injection is feasible with existing technologies. It could also be implemented in a very short period of time and at a relatively low cost. Because stratospheric aerosols naturally fall out of the atmosphere, the benefits/effects of this approach are temporary, generally lasting between 1 to 2 years. It is considered relatively safe for the environment because volcanoes have been injecting sulfate aerosols into the stratosphere for eons and the biosphere naturally processes sulfates using multiple pathways in the sulfur biogeochemical cycle.Besides sulfate, other reflective aerosols that arebeing consideredfor this solar radiation management approach. Theseaerosols include black carbon, metallic aluminum, aluminum oxide and barium titanate(Effiong and Neitzel, 2016).

"What are the Dangers Associated with it?

"Unfortunately, there are dangers associated with stratospheric aerosol injection. This approach may reduce rainfall in some areas of the world.Loss of crops and access to fresh water due to reduced rainfall could lead to starvation and suffering. If this approach were used, it would be important to develop and implement measures to protect people and save lives and livelihoods.Despitethe potentialproblemswith this method, thebenefits could exponentially outweigh its downsides."
