UN IPCC Expert Reviewer Dr. Vincent Gray’s Comments to the IPCC WG1 AR5 Second Draft: ‘You have failed once more to show that the climate is influenced in any way by changes in emissions of trace gases’
Gray to IPCC: 'Globally averaged near surface temperature" What nonsense! Nobody has ever measured such a quantity. It would require simultaneous measurements of thermometers situated randomly over the entire earth's surface, including the oceans.' - 'Detection' and 'Attribution' are mechanisms of organised guesswork They provide only speculation, not evidence of cause and effect'
