What's think of the climatic changes?

Some of it is probably from global warming but it could easily be just changes in the earth as well. Do some research on the earth and you'll find out that it has changed countless times. You know how it used to be Pangea, or how the Sierra Desert used to be a wonderful land full of life. Utopias turn to deserts and deserts turn back to utopias all over the span of thousands of years, sometimes even quicker. You can't always believe everything the scientists or media says because they don't know everything. And alot of times it's just estimated or best guesses. I still don't believe we evolved from apes and they still can't prove it :P.
