Denial...It's More Than Just A River In Egypt.

The climate campaign is a movement unable to hide its decline. Skeptics and critics of climate alarmism have long been called “deniers,” with the comparison to Holocaust denial made explicit, but the denier label now more accurately fits the climate campaigners. Their first line of defense was that the acknowledged errors amount to a few isolated and inconsequential points in the report of the IPCC’s Working Group II, which studies the effects of global warming, and not the more important report of the IPCC’s Working Group I, which is about the science of global warming. Working Group I, this argument goes, is where the real action is, as it deals with the computer models and temperature data on which the “consensus” conclusion is based that the Earth has warmed by about 0.8 degrees Celsius over the last century, that human-generated greenhouse gases are overwhelmingly responsible for this rise, and that we may expect up to 4 degrees Celsius of further warming if greenhouse gas emissions aren’t stopped by mid-century. As Gore put it in his February 28 Times article, “the overwhelming consensus on global warming remains unchanged.” I note in passing that the 2007 Working Group I report uses the terms “uncertain” or “uncertainty” more than 1,300 times in its 987 pages, including what it identified as 54 “key uncertainties” limiting our mastery of climate prediction.

This central pillar of the climate campaign is unlikely to survive much longer, and each repetition of the “science-is-settled” mantra inflicts more damage on the credibility of the climate science community. The scientist at the center of the Climategate scandal at East Anglia University, Phil (“hide the decline”) Jones dealt the science-is-settled narrative a huge blow with his candid admission in a BBC interview that his surface temperature data are in such disarray they probably cannot be verified or replicated, that the medieval warm period may have been as warm as today, and that he agrees that there has been no statistically significant global warming for the last 15 years—all three points that climate campaigners have been bitterly contesting.
