The National Climate Assessment (NCA) is a quadrennial assessment mandated by the Global Change Research Act of 1990. The report, led by the U.S. Global Change Research Program, evaluates the current state of the science of global change and analyzes the effects of global change on regions and sectors of the United States. In addition, each NCA is required to analyze trends in global change for the subsequent 25 to 100 years. To date, four NCAs have been released, the most recent in 2018. Work on the fifth assessment, NCA5, is currently underway.

The NCA5 development process includes a number of opportunities for stakeholder engagement, including several requests for public review of drafts, a public call for technical inputs, and a public call for authors. This talk will share the latest updates on NCA5’s structure, process, and next steps. Presentations will be followed by audience discussion, with the goal of gaining feedback regarding scope and direction of NCA5.
