Know what's really depressing... what may explain record warming this year was phase-out of sulfur fuel used in cargo ships 2020.
Sulfur emissions into the air kept warming lower than it should have been due to thr "global dimming" effect.

So, I guess in a way geoengineering is already occurring... it's just really reckless and unmanaged. Feels bad. 😞
