Why do we fear carbon emissions? Because climate change will make swaths of planet uninhabitable and/or underwater, forcing people there to move.
Don't tell me your solution is preventively moving half billion people. Isn't that the result you wanted to avoid? What's the principial difference anyway between land becoming uninhabitably hot and land becoming uninhabitably cold (due to lack of heating)? You lose land either way and have to move people from it, worsening situation everywhere else.
Your solution is basically shooting yourself in the foot to avoid gangrene, and the amount of faith you have in such solution is disturbing. Your position is one big reason why climate change deniers exist: because you scare people with your misdirected zeal.
