I am more inclined to believe man is having an impact on climate change. The majority of scientists do believe this. There are those who don't but I have found that some of those have ties to the oil industry, political think tanks or some other organization who will gain from skepticism on this. The email scandal in the UK, called ClimateGate, did not actually indicate a conspiracy. It just gave the skeptics something to run with. We seem to have a propensity to believe what is convenient and also to distrust the so called experts and I believe that is what is going on, here.
