This is a talk I gave to students at Vrije Universiteit in Amsterdam yesterday--where Richard Tol has a fractional appointment. It's probably the most impassioned speech I have given on this topic to date.
The more I delve into mainstream climate change economics, the more ludicrous attempts I find to reach a pre-ordained view that climate change is no big deal. One of my patrons put this very well: "Tol and Nordhaus, in my view, quite obviously reasoned backwards from a minimalist conclusion and sewed up their data to make it fit. The IPCC did the same thing to create their risk evaluations."
