Ep. 028: No Computer Models for Global Warming

Guest: Dr. Ken Green, Fraser Institute

"Computer models never predicted an 18 year temperature pause."

That is the claim from Dr. Ken Green, author of "Global Warming: Understanding the Debate" and the Senior Director at the Centre for Natural Resources at the Fraser Institute.

Green says, “When you enter the land of climate modelling, you are no longer doing normative science. I’m deeply skeptical of computer models of any type, climate or economic. Who, six months ago, would have predicted the current price of oil?”

He agrees the climate is changing and that human generated greenhouses gases are affecting it. However, he says, “It’s the assumptions that lead to the higher estimates of warming that are placed in the computer models, that I don’t regard in the same category as normative science.”
