Trump’s National Climate Assessment: No funding and all authors cut loose
The assessment is required by law, but the administration is not noted for caring.

As part of the Global Change Research Act of 1990, Congress mandated that every four years, the government must produce a National Climate Assessment. This document is intended to provide an overview of the changing state of our knowledge about the process itself and its impact on our environment. Past versions have been comprehensive and involved the work of hundreds of scientists, all coordinated by the US's Global Change Research Program.
It's not clear what the next report will look like. Two weeks after cutting funding for the organization that coordinates the report's production, the Trump administration has apparently informed all the authors working on it that their services are no longer needed.
The National Climate Assessment has typically been like a somewhat smaller-scale version of the IPCC reports, with a greater focus on impacts in the US. It is a very detailed look at the state of climate science, the impacts warming is having on the US, and our efforts to limit warming and deal with those impacts. Various agencies and local governments have used it to help plan for the expected impacts of our warming climate.
