I suppose the silver lining is if you look at what the Europeans and Canadians have done on global warming it is remarkably little, just enough to get some good press, but not enough to do serious damage to their economies. If you look at what they do and not what they say, they don't buy the bull much more than we do.
Even if the next Pres mouths a lot of words about international cooperation and fighting climate change and all, little will change. Nobody is meeting their quotas. Nobody will. Costs will rise as usual, but the megacorporations will survive that. Marginal companies will be out of business, which is what is happening anyway. Overall, little change.
