Writing about the mainstream climatologists’ attempt to restore their credibility on March 2nd, John Broder of The New York Times all but dismisses the flaws in the United Nations Intergovernmental Panel on Climate Change 2007 report:

No scientific body is under more hostile scrutiny than the United Nations Intergovernmental Panel on Climate Change, which compiles the climate research of hundreds of scientists around the globe into periodic reports intended to be the definitive statement of the science and a guide for policy makers. Critics, citing several relatively minor errors in its most recent report and charges of conflict of interest against its leader, Rajendra K. Pachauri, are calling for the I.P.C.C. to be disbanded or radically reformed.

Several revelations forced the IPCC to retract several part of its most recent report. Although the study says the probability of the Himalayan glaciers will melt by 2035 or sooner is “very high”, the authors acknowledged that those claims were based on speculation. Further, the IPCC’s assessment of reductions in mountain ice in the Andes, Alps and Africa came from two dubious sources. One was from a magazine that discussed anecdotal evidence from mountain climbers and the other came from a student’s dissertation. The IPCC also acknowledged overstating crop loss in Africa, Amazon rain forest depletion, sea level increases in the Netherlands and damage from weather catastrophes.#

Even before these recent gaffes, prolific climatologists questioned the IPCC’s findings. University of Virginia professor Fred Singer recently published an 800-page report entitled, “Climate Change Reconsidered” that questions and debunks many of the conclusions found by the IPCC report and emphasizes that the science behind climate change is not settled.# Richard Lindzen, professor of meteorology at the Massachusetts Institute of Technology notes that IPCC’s models fail to take into account naturally occurring cycles as El Nino, the Pacific Decadal Oscillation, the Atlantic Multidecadal Oscillation and more.#

These errors are anything but minor.
