That's already a problem. Developing nations are consuming an ever expanding amount of fossil fuels. And they're sure as hell not going to stop, because the advantage to their citizens of developing their infrastructure towards Western standards of living far outweighs projected threats of climate change. Developed countries are already making okish strides on decarbonizing, but how can we in the first world effectively decree that the developing world must halt or slow progress towards the lifestyles that we enjoy. That reeks of a new kind of colonialism, and simply won't go over well without the threat of global violence. The only way we'll actually make strides on decarbonization is with some kind of global carbon tax. I'm not going to pretend I know how we accomplish that, but if we can't, we're not going to mitigate climate change in any reasonable way.
