There's no general will, it's not specifically political will. Emitting less CO2 means doing less things or doing them for much more money due to high taxes to discourage it (and also disproportionately affect poor people). Other than some luddites I've never met anyone that genuinely was willing to sacrifice eating a nice steak or going on vacation unless they are millionaires, and that's only because those people know they can do it as much as they want. You have a huge mass of people getting lifted from poverty that will tell you to fuck off if you tell them that now they are finally out of eating rice and starving they can't have a steak, because of CO2.

All the things silicon valley "caviar communists" say you need to stop doing are basically the dreams of a whole mass of people coming out of poverty. Nice food, traveling, having a car, having A/C, etc.

So we can either find alternatives, or slowly figure out more geoengineering projects like mass absorbing CO2 and the like.
