The National Climate Assessment summarizes the impacts of climate change on the United States, now and in the future.

Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. Global climate change has already resulted in a wide range of impacts across every region of the country and many sectors of the economy that are expected to grow in the coming decades.
USGCRP’s Third National Climate Assessment (NCA) was informed by extensive public input gathered through town hall meetings, public comment periods, technical workshops, and other participatory opportunities across the country. The NCA engagement strategy leveraged science and assessment capacity across the country while working to ensure that the process and outcomes were accessible and useful to stakeholders. The information below documents stakeholder engagement around the Third NCA.
