im not saying the earth isnt getting warmer, but al gore wants you to believe that its all man kinds fault. there is not evidence to prove that. do the research and you will find out that the evidence isnt conclusive to say that it is all man kinds fault. we, as humans, may have contribuated to some degree but not the way al gore would want you to believe. for every scientist that says its mans fault their is another that says it isnt and this is just a natural cycle in earth existance and that earth has gone through cylces like this before.
before you take any political talking heads word on this subject, especially al gore of all people, just do some research into the subject from all sides.
