What if that was a long term mistake. https://en.wikipedia.org/wiki/Stratospheric_aerosol_injection https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio... > Stratospheric aerosol injection is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming and increased albedo, which occurs naturally from volcanic winter.

I recall a suggestion that jets should "run rich" which would increase the water vapor in the exhaust and create more contrails in combination with eliminating redeye flights so that contrails aren't formed at night (allowing more radiative escape) https://en.wikipedia.org/wiki/Marine_cloud_brightening https://en.wikipedia.org/wiki/Marine_cloud_brightening > Marine cloud brightening also known as marine cloud seeding and marine cloud engineering is a proposed solar radiation management climate engineering technique that would make clouds brighter, reflecting a small fraction of incoming sunlight back into space in order to offset anthropogenic global warming. Along with stratospheric aerosol injection, it is one of the two solar radiation management methods that may most feasibly have a substantial climate impact.
