Climate skeptics are not necessarily denying that there is global warming -- the climate has always changed.
The point is that the science is not done properly. The data and methods the IPCC based its reports on are not open to scrutiny and review. On this flawed data climate models are based, and on these models governments base their policies in turn.
The strawman fallacy comparing climate skeptics with creationists does not hold. Creationists take holy scripture as a start and try to shoehorn everthing to it; Climate skeptics have no such holy scripture.
Bzzt! Wrong.
The IPCC based its reports in a lot of data open to scrutiny, not only East Anglia's. And even the problems with East Anglia data have been hugelly exagerated. The IPCC meetings were also open to a lot of dissent, particularly from Middle East oil producing countries (guess why)?
And GW deniers do have a basic belief: "you can regulate my energy from my cold dead hands".
