This week, CSIS Energy Security and Climate Change Program Director Joseph Majkut talks with Dr. Robert Kopp, a climate scientist, and professor at Rutgers University, about the Intergovernmental Panel on Climate Change’s Sixth Assessment Report. The contribution of Working Group 1, which reports the physical science of climate change, was released this past August. Dr. Kopp was the lead author of that report's chapter on sea-level rise. They dive into some of the climate science and modeling that supports the IPCC report and discuss the challenge of communicating the findings of a report of this size and scale.
