Climate change is real. It has been going on since the beginning of time. But the assertion that human activity is playing a role in climate change is nonsense.
People who do not understand science need to at least know who to believe. Christie has been all over the place in his quest of who to believe.
Scientists who do not have a vested interest in man caused global warming are the ones from whom to seek advice, not the AGW crowd, a very large group. AGW is an acronym for Anthropogenic Global Warming, or man caused global warming.
I believe Christie is correct that human activity does/can impact global climate change just by virtue of being part of the Eco system. However, if Christie meant to imply that human activity is in any way a major or even significant contributor/cause to the climate change he was really off base and not even in in the ball park. He needs to clarify his position on this with creditable references. He also should explain his acceptance of Muslim friendship.
