According to a report at Climate Depot, Ivy League geologist Robert Giegengack, former chairman of Department of Earth and Environmental Science at the University of Pennsylvania, said he was “appalled” at Gore’s work in his original 2006 film, citing either Gore’s lack of understanding or knowing misrepresentation. “It was irresponsible of Al Gore,” he said.
Lindzen & Happer: "Crusaders will continue to retort that “the science is settled; it is time to act!” But real science is never settled, nor is scientific truth determined by consensus or political diktats. Agreement with observations is the measure of scientific truth." ... "The frenzy over climate resembles the medieval crusades against foreign infidels and home-grown heretics. There is even a children’s climate crusade." ...
"We are both scientists who can attest that the research literature does not support the claim of a climate emergency. Nor will there be one. None of the lurid predictions — dangerously accelerating sea-level rise, increasingly extreme weather, more deadly forest fires, unprecedented warming, etc. — are any more accurate than the fire-and-brimstone sermons used to stoke fanaticism in medieval crusaders." ...
"So far, climate crusaders have refrained from vilifying water vapor and clouds, which make the largest contribution to greenhouse warming of the earth. Carbon dioxide, demonized as “carbon pollution,” is an improbable villain." ... "More carbon dioxide is likely to cause some surface warming. But the warming would be small and benign. In fact, history shows that warmings of a few degrees Celsius — which extended growing seasons — have been good for humanity. The golden age of classical Roman civilization occurred during a warm period. Cooling periods, which were accompanied by barbarian invasions, famines, and plagues, have been bad. Neither contemporary observations nor the geological record support computer-based claims that CO2 is the “control knob” for the earth’s climate."
Analyst Vijay Jayaraj commented: "Where is the climate disorder? What parameters are we talking about? Which Index is he referring to? Is it agriculture success? cumulative increase in Freshwater access? is it poverty reduction? And May I know when the climate was in order? or static?"
Green energy author Rupert Darwall: "Climate disorder ... that's a good one from Macron. Any notable weather event can now be ascribed as evidence of climate disorder, as if once upon a time, the climate was orderly."
