Is man really causing Global warming? Or is it a normal cycle our climate is going through. No doubt the air we breathe is better when we watch what we put into it, but are we all some kind of "rain men", that can change the weather patterns on this planet?

There have been ice ages following by warming trends followed by ice ages throughout the earth's history. In that respect it is cyclic. But never ever before has the impact of man been added into the equation until now. The burning of fossil fuels which dumps huge amounts of CO2 into the atmosphere coupled with the massive destruction of forests which convert CO2 into oxygen is just pushing the limits. The earth may reach a critical point and never recover.
