In this webinar, David Easterling (NOAA/National Centers for Environmental Information), Technical Support Unit and a Federal Coordinating lead author on the Fourth National Climate Assessment (NCA4), will summarize the key scientific findings from the NCA4. CLEAN educators will discuss how teachers can use the NCA4 in their classrooms and point to CLEAN resources that support teaching these topics.

The NCA4 fulfills the Global Change Research Act of 1990 mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report (CSSR). Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods.
