The National Climate Assessment (NCA) is a mandated quadrennial assessment of the risks posed by climate change to our nation and how we can respond to minimize those risks. As part of the Sustained Assessment process, the fourth such assessment, NCA4, is currently in development under the auspices of the US Global Change Research Program (USGCRP). In this listening session, you’ll hear about the NCA4 process, progress to date, and how you can contribute. We’re particularly interested in hearing from stakeholders about how NCA4 can best reflect the impacts you are seeing, the risks posed to the things you care about, and specific case studies worth sharing with the nation.
