About the author, Robert
Christian and economist, Chief Economist at infineo, and Senior Fellow with the Mises Institute.
Listening to Bob read the NPR article, I thought to myself “I recognize the spirit behind that”. So I checked up on the name of the author – and I was right.
Who was it?
Very interesting and informative. I particularly liked the discussions on Null Hypothesis, Confidence Intervals, and Sensitivity Analysis, which seem to be forgotten when discussing Stochastic Simulations of Climate Change. The lack of rigor drives me crazy.
One question:
If the variable associated with Carbon Doubling is so important, and in dispute, then why isn’t it modeled as a distribution rather than a single value?
Given the relative speed of conducting Simulations (when I started modeling in the late 80’s it’d take 8 hours to do a single simulation run; in the 2015’s I could do 10,000 passes in 5 minutes) I don’t understand how applying a deterministic value to what is clearly a disputed variable can pass muster.
