evidence: WSD authors conclude that "neither the rate nor the magnitude of the reported late twentieth century surface warming (1979-2000) lay outside normal natural variability, nor was it in any way unusual compared to earlier episodes in Earth’s climatic history" (p. 84). This statement is an example of cherry picking data that conveniently fails to account for the increase in temperatures over the last 19 years. At what point would temperatures and climate changes be labeled as unusual or beyond the parameters of natural variability? There is no mention of a benchmark to indicate that threshold. WSD authors write, "Though the range of natural variation has yet to be fully described, evidence is lacking for any recent changes in global ocean circulation that lie outside natural variation or were forced by human CO2 emissions" (p. 92). How can one claim natural variability without being able to define it?
