Global warming exists. There is no point in denying it, all you're doing by doing so is admitting a lack of willingness or knowledge of dealing with the issue. No matter which way you look at it, the world's population has never even been anywhere nearly as close to what it is right now. The farting from all those people and the animals that are used to feed them, coupled with the declining forests of the world, is probably enough by itself to cause problems. People who deny the effects of civilian and industrial emissions are either too intimidated by the size of the problem or simply have no grasp of it. Shifts in global climates have occured before, but none have caused the pollar ice caps to melt, none bringing about rises in water levels around the world that were nearly as drastic as the ones we are witnessing.

Get real, anyone who says global warming is not true and that it's just something made up by a buch of hippies.
