I think this man made climate change BS is just a method to control emerging markets (China, India others). FACT; Earth is 4.3 billion yrs old their has always been climate changes, todays deserts were under water millions of yrs ago and their wasnt a man insight to change earth climate. More understanding has to be explained by scientists to convince myself, Al Gore noble is not a starter, why cant scientists provide us with the research focusing on natural climate changes, and a comparison of how mankind effected this trend, what do u think? are u skeptical like myself,or do u have logical facts? thanx
