It has been stated that climate change can take thousands, if not millions of years to come about naturally. The argument is that mankind is speeding up that process. I can sort of understand that thought. However, there is also a caveat inserted into the whole arguement that the world indeed does go through a heating and cooling cycles. Heck we even name periods of time after them, "Ice Age" anyone? These have been proven, time and time again. This is not what people argue about.

The real arguement is whether the amount of "helping along" of this process by mankind is anything to be worried about. I personally think not. But you are welcome to your own observations. It's hard to change people's minds, especially where one is trying to "prove something" that the other person just doesn't care about. Tell a farmer to turn in his dually for a smart car.... ain't going to happen.
