Shame on The IPCC: Climate Change Consensus Was Phoney – Climate Gate Continues

The IPCC consensus on climate change was phoney, says IPCC insider


Claims that 2500 scientists agreed were "disingenuous"

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.”

Hulme, Professor of Climate Change in the School of Environmental Sciences at the University of East Anglia –  the university of Climategate fame is the founding Director of the Tyndall Centre for Climate Change Research and one of the UK’s most prominent climate scientists. Among his many roles in the climate change establishment, Hulme was the IPCC’s co-ordinating Lead Author for its chapter on ‘Climate scenario development’ for its Third Assessment Report and a contributing author of several other chapters.

Hulme’s depiction of IPCC’s exaggeration of the number of scientists who backed its claim about man-made climate change can be found on pages 10 and 11 of his paper, found here.

Additional quotes taken from his paper:

Consensus and Uncertainty

Understanding consensus as a process of ‘truth creation’ (or the more nuanced ‘knowledge production’) which marginalizes dissenting voices – as has frequently been portrayed by some of the IPCC’s critics does not do justice to the process {the process of scientific investigation} ….

Consensus-building in fact serves several different goals. As Horst and Irwin have explained, seeking consensus can be as much about building a community identity – what Haas refers to as an epistemic community – as it is about seeking the ‘truth’.

Pielke and Sarewitz agree that the IPCC has failed in its role as an ‘honest-broker’ and has moved towards being an ‘issue advocate’ in Pielke’s terminology, or even on some occasions a ‘stealth issue advocate’.

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. { –adjective lacking in frankness, candor, or sincerity; falsely or hypocritically ingenuous; insincere: Her excuse was rather disingenuous}.

That particular consensus judgment, as are many others in the IPCC reports, is reached by only a few dozen experts ….. questions about the status of climate change knowledge synthesized by the IPCC remain less widely investigated, questions which emerge from the agendas raised by the new geographers of science ……….knowledge that is claimed by its producers to have universal authority is received and interpreted very differently in different settings. …………
