Russia is gonna be awesome in 60+ years. All global warming is going to do to them is give them more decent farmland. They don't give a fuck. And in the meantime, they're just going to go on pumping out oil and gas, undercutting OPEC prices constantly and building up friends in Europe. If they end up reintegrating the Near Abroad, their demographic decline, which has been overstated anyway, will be reversed entirely in a "Greater Russia" of 230 million, stretching from the Ukraine to central Kazakhstan, and even if they don't the population is still growing at a sustainable rate. Sure, they'll fuck up eventually, it's Russia, after all, but in the medium term, they're pretty good.
