Jake I am sure you know there are plenty of research papers from prestigious universities that question mans contribution to climate change. Here's one -

Plenty more out there.
Sadly there seems to be a group of bullies at the IPCC that like to cause problems for anybody that dares to speak out against them. They have 'denormalised' anybody that does not agree and made out basic scientific questioning to be tin foil hat lunacy. Why would proper scientists with verifiable, repeatable work be like that? If they weren't I would have faith but the credibility is shot for me. The models cannot be used to predict yesterday, they over simplify and miss out little things like water vapour.
Show me a body of papers that have released the raw data like normal science protocol and still withstood all criticism.
31000 American science graduates signed up as sceptics, not deniers just open minded and doubtful. That's just in the USA mind. A Greenpeace poll found 47% of physical sciencists did not agree with AGW theories.
