When the people screaming about global warming the loudest adjust their personal lives as if it were important on their own, without waiting for government to FORCE them, and everyone else, to do so, then I will give them a listen. Do we really need global warming, i mean, climate change, conferences at exotic destinations all around the globe where people travel to in CO2 spewing jets just to castigate the sheeple because they like to drive Chargers instead of Priuses? Teleconference, sell your private jet, take commercial air if you must. Stop the limos, downsize your house, without being forced to by governent actions, then I will listen.
besides, it may end up being cheaper to just use our technology and resources to learn to adapt to the change instead of thinking that we can somehow change it 'back'.
