Climate change consensus: From 2,500 to a few dozen

From the National Post (via Jim Hoft), we get the admission by a leading IPCC R4 author that the much vaunted consensus on climate change didn't include 2,500 scientists, but actually only a handful: The IPCC consensus on climate change was phoney, says IPCC insider
The UN’s Intergovernmental Panel on Climate Change misled the press and public into believing that thousands of scientists backed its claims on manmade global warming, according to Mike Hulme, a prominent climate scientist and IPCC insider. The actual number of scientists who backed that claim was “only a few dozen experts,” he states in a paper for Progress in Physical Geography, co-authored with student Martin Mahony.

“Claims such as ‘2,500 of the world’s leading scientists have reached a consensus that human activities are having a significant influence on the climate’ are disingenuous,” the paper states unambiguously, adding that they rendered “the IPCC vulnerable to outside criticism.”
The paper mentioned in the article can be found here (pdf). On page 10-11 of that paper we find the following snippet:
Without a careful explanation about what it means, this drive for consensus can leave the IPCC vulnerable to outside criticism. Claims such as ‘2,500 of the world’s leading scientists have reached a consensus that human activities are having a significant influence on the climate’ are disingenuous. That particular consensus judgement, as are many others in the IPCC reports, is reached by only a few dozen experts in the specific field of detection and attribution studies; other IPCC authors are experts in other fields.
It's a little late, but I am glad to see the truth finally coming out!
