Dismissing the global warming skeptics

Despite the fact that the evidence for climate change is now overwhelming some people still don't want to believe. They would prefer to think it is some kind of conspiracy, hoax or scam. George Monbiot suggests four questions for the skeptics.

1. Does the atmosphere contain carbon dioxide?
2. Does atmospheric carbon dioxide influence global temperatures?
3. Will that influence be enhanced by the addition of more carbon dioxide?
4. Have human activities led to a net emission of carbon dioxide?

He also has debunks some of the junk science put forward. In this case the ridiculous claims of David Bellamy. Paradoxically a Google search for junk science brings up JunkScience.com as the first result. This website actually tries to prove that global warming is a hoax. I would like to ask them to produce a single refereed article from a reputable scientific journal proving it.
