I'm all in on this idea. Let's be real climate change is a global problem, not a specific country problem. I don't care how many initiatives and policies the West implements, even if we went 100% greenhouse gas free China alone accounts for a third of global emissions, so what's the point of we give other places a pass to pollute?
And no they should not be given time to catch up on polluting the Earth lol, you think the Earth gives a crap who's polluting and when they started?
So I only see geo engineering as a practical solution to this global problem.
It's actually feasible to cool the Earth back to preindustrial levels by annual releases of aerosols in the stratosphere, and the cost would be something like 20 to 40 billion dollars, a drop in the bucket.
I hope this takes off and we go all in on this.
