Conspiracy Theorists and Vaccine Skeptics Have a New Target: Geoengineering | Around the country, people with a deep distrust of government want to preemptively ban the use of aerosols to reduce heat
Agreed geoengineering is bad science/engineering IMO. You can't know what the long term effects would be until after its been deployed. The safest bet would be to just ditch fossil fuels but that's not as sexy.
Also, we already have examples of tech bros creating a business where companies pay them to offset their carbon footprint by shooting unknown chemicals of unknown quantities into the upper atmosphere.
