The version of the Reference Manual on the NASEM website still has the climate science chapter.
The FJC website has a version without the climate science chapter. There is a note that the chapter was removed on February 6, 2026.
Perhaps the two organizations should talk?
The FJC retraction has been covered by many media outlets, but the failure of NASEM to act has not been reported, as far as I can see.[1]
