And anyone who believes the cost would be a mere $50 billion/year is 1) naive and 2) missing the more subtle point that, if the total cost of the "ravages of global warming" is a scant $50 billion, then it's hardly worth worrying about. Of course, were America to give in to this sort of extortion, which would be bad enough, we'd find the cost to be much higher--up to and including the eventual destruction of the American economy.

Which is, of course, the Left's ultimate objective.
