Inconvienent Truth

I do not agree with Al Gore's position in Inconvienent Truth. I understand his point of view in that he is concerned with the future of the earth and longevity of the environment but personally through my own research and study ( I wrote a paper on Global Warming earlier in the semester) I believe that Co2 emissions have a minimal role in the earth's slight temperature rise. On the contrary I think the earth is going through a natural warming trend as research has shown it has multiple times in the past.
