One solution, which I admit is out there, is what if we actively cook the earth? While yes, it would be an engineering challenge, I think it is quite reasonable to create an “adjustable solar shade”. Basically build up enough reflectors at the Lagrange point to selectively “cool” parts of earth. Yes, it would be a massive undertaking, but could potentially be done mostly autonomously. If our timeline is 30 years, this may be more achievable than alternatives. Elevator pitch: use materials from asteroids to build huge reflectors in space. Side benefit is it would enable large scale mining of the sky.
