Development of the Fifth National Climate Assessment (NCA5) is currently underway, with anticipated delivery in 2023. This content will be updated as new information becomes available.
The U.S. Global Change Research Program (USGCRP) was established by Presidential initiative in 1989 and mandated by Congress in the Global Change Research Act (GCRA) of 1990. Its mandate is to develop and coordinate “a comprehensive and integrated United States research program which will assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change.”
NCA5 will assess current and future risks posed by climate change to each of NCA’s 10 regions, illustrated below.
