Your argument is a typically conservative one and merely a shallow justification for selfish behavior and disregard for environmental stewardship and the quality of life that future generations will inherit.
Granting that global warming is happening (which indeed is supported by the evidence), the question of what to do about it remains a complex one influenced by many social, political enconomic,and technological factors. This sort of demonization of positions other than your own hardly constitutes a constructive contribution to the discussion.
Let me say this. If you want to see something 'economy-crippling' just watch us stay the present course, because the American economy won't just be crippled by the consequences of global warming, it will eventually collapse to a mere shadow of its former self.
Plese provide empirical evidence that this scenario is certain or highly probable.
