Asking tough questions about the science, technology, and politics of climate change, two climate researchers challenge leading experts on one of the defining issues of our age. Every two weeks, they explore how we can fight global warming by cutting greenhouse gas emissions, carbon removal, adaptation and solar geoengineering. Dr. Jesse Reynolds and Dr. Pete Irvine consider the roles of computer models and persuasive narratives, economics and public policy, and renewable energy and national security in the climate debate, and look beyond to issues such as biotechnology and international development.
