But Bill Gates, the smartest man on the earth, says it will work...

Even assuming that an experiment is done for, say, twenty years, I don't know how accurately we can forecast longer- term changes (over a scale of centuries) from this move. Heck, making these forecasts without the sun being blocked out is hard enough.

Completely agree. My statement was made in jest (I don't know how else to deal with this completely bonkers situation, except with humor). It terrifies me how the same individuals who claim/promise to want to save humanity are also the ones locking up our shared inheritance. [1]

Totally! As a different commenter noted, it seems that people will consider any technological solution to warming except politically unpalatable ones.

The spectre of job losses and so on are frequently raised when it comes to transitioning away from fossil fuels --- as though the economic catastrophe from continued global warming would be lower.
