Rachel, you'll have to do some serious fact-checking on this dude. What's he talking about, denying that a consensus of the world's scientific community agrees global warming is real?! The frightening thing about it is, if you google the term you'll get hundreds, if not thousands, of junk science climate change denialist sites with misleading headings. The breadth and scope of this assault on the science is mind-bending. They're consistently spotty on facts and science but highly politicized sites that attack the messenger.
One example are efforts to debunk the National Academy of Science (NAS) report, which found that 98% of scientists believe global warming is real. These sites don't attack the science, rather they challenge the credentials of the report's authors. But as far as most scientists are concerned, the question is no longer in dispute. And if you still don't believe the NAS, Take your pick of 18 scientific associations, compiled by the Union of Concerned Scientists.
