Agreed on geoengineering. But given that AC is a non-trivial fraction of current energy use [1] and that there are ~2B low-energy consumers in the tropics who would enormously benefit from AC, the in-principle impact on GHG output here is substantial. Install to cool the earth: no. Install to cool human-occupied spaces: yes. [1] https://energy.gov/energysaver/air-conditioning https://energy.gov/energysaver/air-conditioning
