Char, the sources sited by the "scientific community" that is running around screaming the sky is falling are basing their assumptions on trace amounts of CO2 and a slight temperature rise. They're nothing but a bunch of chicken littles running around with their pet emergency. After Global Warming, they'll move on to something else. Like cow flatulation or some idiotic stuff like that. By the way, cow flatulation creates more pollution than your average coal plant.
