The reports are still available buried in the NOAA archives. NCA5 is here: repository.library.noaa.gov/view/noaa/61...

Working on the NCA5 was amazing. It was genuinely moving to be surrounded by so much dedication and sheer scientific and administrative *excellence*. I think we’ve forgotten how to believe in good things, but this was one of them.
I was honored to work on the 5th National Climate Assessment in 2022-23. One of my most inspiring moments in climate was sitting in a hotel ballroom with hundreds of experts, scientists, and civil servants, all working to inform Americans about our possible futures. www.nytimes.com/2025/04/28/c...
