Nicholas Stern was on the BBC's Hardtalk show, being grilled by Zeinab Badawi about his recent report.
For a BBC journalist, Badawi did not too bad a job of taking potshots at Stern, with ammunition apparently sourced from Richard Tol. I was amused when she called Stern a "climate lobbyist", before correcting herself.
Stern himself was deeply unimpressive, with the mannerisms and delivery of a minor council official rather than a great academic sage and, as Pielke Jr notes on Twitter, constantly resorting to namedropping rather than rational argument. I was struck also by his allegation that Tol builds his conclusions into his economic models. This struck me as quite a strong thing to say.
