this is why mitigation of climate change is impossible. China and India are not going to want to give up their newfound economies and infrastructures just to save a few polar bears. They won't want to go back to being less economic developed countries. Who gave us the authority to decide that they should stop industrialising. We did the same thing in the 1750s and now the climate is suffering because of it. Now the Chinese are doing the same thing.they are entitled to do it - just because we now know its damaging the climate doesn't mean that they should stop we didn't.
This is why any mitigation of Co2 we do will have no effect in the long run. The best thing to do is to adapt and prepare for the effects of climate change
