Stuff They Don't Want You To Know CLASSIC: Stratospheric Aerosol Injections: Saving the World with Chemtrails
Oct 22, 2025
Exploring the contentious topic of chemtrails, hosts discuss how stratospheric aerosol injections (SAI) could combat climate change. They dive into the science behind SAI, its potential benefits, and the technological hurdles it faces. The conversation touches on the ethical implications of prioritizing global benefits over regional harms. Concerns about governance, equity, and the longevity of aerosol effects are also examined. Could SAI really be a step toward saving the planet, or is it merely a temporary fix?

Episode notes
Volcanoes As A Model For Cooling
- Stratospheric aerosol injection (SAI) proposes mimicking volcanic aerosols to cool Earth by reflecting sunlight.
- Models and past volcanic eruptions show this could lower surface and ocean temperatures quickly if implemented correctly.
Feasibility And Cost Are Lower Than Expected
- SAI is technically feasible with existing platforms but needs specialized delivery systems to reach ~60,000 feet.
- Cost estimates suggest deployment could be billions, not trillions, making it financially accessible to wealthy actors or states.
SAI Requires Continuous Commitment
- Aerosol particles in the stratosphere are short-lived and require continuous replenishment.
- That implies an indefinite, sustained program rather than a one-off fix.
