Roger Pielke Jr. is a political scientist who writes on a diverse range of policy and governance issues related to science, technology, environment, innovation and sports. He is most famous (or infamous?) for his work on climate change. We cover his Iron Law of climate policy, his views on the problems with business-as-usual climate scenarios, and the challenges of attributing extreme weather. We also touch on the extent of his relationships with climate change skeptics and the efforts to discredit him, including the congressional investigation into his funding.

Roger is a Professor at the Department of Environmental Studies at the University of Colorado in Boulder. He is the author of The Climate Fix: What Scientists and Politicians Won’t Tell you About Global Warming, The Honest Broker: Making Sense of Science in Policy and Politics, and The Rightful Place of Science: Disasters & Climate Change .
