Geo-engineering should be an absolute last resort and should not be considered viable until we are on the brink of destruction. We need to cut emissions not spray more chemicals into the sky because we're too fucking greedy to actually fix the problem.
Power generation is only one part of the problem, so I have questions for you. Do you support zoning reform? Do you support bike infrastructure and public transportation? Do you support spending billions on rail projects to curb plane use?
We can't techbro ourselves out of this problem, society needs to fundamentally change in order to solve climate change. Are you willing to change your way of life?
