No one knows anything that they think they know about "Global Warming"....That being said the Earth is around 3.5 to 4.6 billion years old. BILLIONS!!! Of years, the "Expert Scientests" can get wonderful data from the glaciers and all but thats only Hundreds of thousands of years of data( NOT EVEN CLOSE TO THE 3.5 - 4.6 BILLION THAT THE EARTH HAS BEEN HERE) and there are still more billions of year to look at after that. So knowing that how can anyone in there rite mind say that they have the answer to this question of global warming. Everything is speculation. I mean, shit, its priddy fucking obvious that theres a fucking pattern of co2 build up and what not but, we are just making what we think is an educated guess about the situation. Theres no way that one can think they have the real answer to our problem( UNLESS THEY LEAVE OUT EVIDENCE THAT IS AGAINST THEIR ARGUMENT )
Because there is simply no know way to figure out if it ever happend before(global warming) or not.

So I say just like with religion, we are( as a world ) making up answers for what we do not know about.
