Highlights

•

It is uncertain whether Stratospheric Aerosol Injection(SAI) research is justifiable, but a tentative case be made for security-focused research.

•

SAI would eliminate the arguable environmental existential risks of climate change (<1% – 3.5%).

•

It is extremely unclear whether SAI would reduce willingness to mitigate, and extensive efforts should be made to reduce the risk of mitigation obstruction.

•

Termination shock risk is overstated.

•

The risk of unilateral deployment is overstated, but SAI introduces other serious security risks.
