Shoot! If only we had signed Kyoto...
But then we would really be in trouble because the ice age would be come even faster. As citizens of the world, we have a patriotic and environmental duty to create as much carbon dioxide as possible to increase global warming and to forestall the coming ice age. Just close your eyes, click your heels together 3 times, fart twice (methane is a greenhouse gas), and repeat to yourself out loud over and over, "humans CAN control the weather, humans CAN control the weather, ...."! By talking out loud, your carbon dioxide output will be greatly enhanced.
