Show Summary
On this episode, Nate is joined by climate and policy scientist Roger Pielke Jr. to discuss the progression of climate research and modeling. The climate activist community is based around projections of what a future might look like given the actions of society - an important tool in the push for urgent climate action. Yet, just like with any other model, the assumptions and parameters can greatly shape the outcomes. How has climate science been shaped by previous models and public perception? How did 2Cº come to be our common climate goal post? Are we anticipating the future within the most likely range of possibilities, or are we polarizing ourselves to the extremes of climate denial and climate doom?
About Roger Pielke Jr.
Dr. Roger Pielke Jr. is a professor at the University of Colorado where he teaches environmental science and policy. A lifetime scholar with many interests, Roger researches and writes on subjects from understanding the politicization of science to decision making under uncertainty to policy education for scientists in areas such as climate change, disaster mitigation, and world trade. His most recent book, The Rightful Place of Science: Disasters and Climate Change takes a deeper look at the IPCC and climate science and how it is being interpreted in the media. Roger also oversees a popular Substack - The Honest Broker - where he is experimenting with a new approach to research, writing and public engagement.
