The U.S. Global Change Research Program (USGCRP) is pleased to announce the release of the Fifth National Climate Assessment (NCA5). Led by USGCRP and its 14 member agencies, NCA5 draws on the expertise of nearly 500 authors and 250 contributors from every state, as well as Guam, Puerto Rico, and the U.S. Virgin Islands. NCA5 is the most up-to-date and comprehensive assessment of climate change in the United States, providing authoritative, decision-relevant information on how people across the country are experiencing climate change, the risks we face now and in the future, and actions underway to reduce greenhouse gas emissions and build resilience. USGCRP is providing a series of webinars led by the authors of key chapters of this report. These chapter webinars are an opportunity for you to hear about the findings of a particular chapter from the authors themselves. Each virtual one-hour event is expected to include some time for Q&A.
