Part of the dramatic rise occurring after the 1970s is a direct response to the clean air / pollution legislation that started getting passed in western countries. Pollution seeds the air with potent cloud condensation nuclei, creating a higher average cloud cover, and reflecting more shortwave solar radiation. We've got cleaner healthier air, but less cloudy.

I believe there was also a noticeable effect from the pollution decrease when global shipping dropped during covid, you had less cloud cover from ship trails, and more solar radiation reaching the surface.

Not surprisingly, deliberately polluting it again is a proposed method of reducing global warming. https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio...

Yeah, I mean, wasn't the worst year to be alive some year after a volcano eruption? So, let’s geo engineer this against global warming and hope our calculations pan out…

This mitigation strategy is so obvious I'm surprised that this isn't implemented already.
