PragerU post by Happer uses flawed reasoning to claim that climate models always fail
"climate models that attempt to predict the future temperature of the planet...don’t work. They haven’t worked in the past. They don’t work now."; "the number of factors that influence climate—the sun, the earth’s orbital properties, oceans, clouds, and, yes, industrial man—is huge and enormously variable"; "CO2 is a minor contributor to the warming of the earth"

Climate sensitivity estimate given in Heartland Institute’s report is misleading
Doubling the concentration of atmospheric CO2 from its pre-industrial level, in the absence of other forcings and feedbacks, would likely cause a warming of ~0.3°C to 1.1°C
