You don't seem to understand what you are talking about. The Earth has gone through many diffrent cycles in it's existance. Warming and cooling such as Ice Ages and so on are normal climate cycles that happen to the Earth over thousands or even millions of years.
Man made global warming is causing the changes to happen far too fast. Meaning something that should have taken hundreds or even thousands of years is happening in 50 years.
