Today's guest is Bob Murphy of Texas Tech University. We discuss his work on climate change and the social cost of carbon. Bob started working on issues related to climate change when he started working with the Institute for Energy Research. We discuss the implications of the Integrated Assessment Models (IAMs) used to evaluate the impact of climate change, the pivotal role played by discount rates in evaluating any kind of climate policy, the pitfalls of carbon taxation, and the opportunities presented by geo-engineering technologies. Here are some links to articles we mentioned in the episode: William Nordhaus versus the United Nations on Climate Change Economics The Case Against a U.S. Carbon Tax The Benefits of Procrastination: The Economics of Geo-engineering
