C'mon people, I know your all a bit more intelligent than that. Don't just take global warming on because a few well intentioned greenies with whacky computer models tell you it's true as gospel. here's some facts to ponder, there is no true evidence that the earths atmosphere is warmer today than it was 100 years ago, melting of sea ice will REDUCE the volume of sea levels not increase them as water expands when it freezes and contracts as it thaws (yes land locked ice can contribute but is offset by the amount of sea ice melting), man can not make carbon, it already exists, by burning it we are only moving it from underground to above ground, is Man not a natural inhabitant of this planet? If so then what we do IS natural.
