What to do about it is easy.
We have to replace coal fired power plants with nuclear ones. All other technological options are not ready to start solving the problem (at the scales needed) right now.
I am actually frustrated that there is not a nuclear plant being built now near my city. I live in a very sparsely populated area that is geologically stable. We already have much of the power infrastructure in place for windmills and a natural gas power plant. Nuclear would be a sensible addition and expansion.
If you say you want to solve global warming and you say that we can't build nuclear power plants, you're a hypocrite.
Ironically the same people the argue with "deniers" about the problem argue against nuclear as part of the solution. So switching to working on the solution actually doesn't end the argument, it just creates a reactionary hypocrisy that makes your head hurt.
