May I suggest butcherboy that you read some of the information criticising the ipcc, much of it coming from the scientists (there were a few amongst the bureaucrats). Here's an excerpt from one of the links I provided above, only a few words
"The IPCC is not and never has been an organisation that examines all aspects of climate change in a neutral and impartial manner. Its internal procedures reinforce that bias; it makes no attempts to clarify its misleading and ambiguous statements. It is very selective about the material included in its reports; its fundamental claims lack evidence. And most importantly, its actions have skewed the entire field of climate science."
