Banning coal is a complete no-brainer at this point. Has been for quite a while. Never mind climate change, it's horribly polluting. The only reason it's still remotely economically viable is because the people who burn coal don't bear the costs of their pollution. If they actually had to compensate people for all the cancer, lung disease, poisoned ground water, contaminated seafood, and other such problems they cause, coal would vanish.

It's already to the point where the ridiculous coal fans who infest our government are forcing coal power plants to remain open when their operators want to close them because they're no longer profitable to operate.
