Donald Trump accuses NASEM of climate fraud in July 2026 statement

On July 22, 2026, former President Donald Trump used his Truth Social platform to allege that the National Academy of Sciences, Engineering, and Medicine (NASEM) had published fraudulent manuals on climate change. He claimed the academy’s reports, including a recent attribution‑science study linking extreme weather to human‑caused climate change, are designed to support multi‑billion‑dollar lawsuits against oil and gas companies and to influence federal judges.

Montana Attorney General Austin Knudsen echoed the criticism, saying the NASEM’s Reference Manual on Scientific Evidence was funded by climate‑litigation groups and authored by academics with limited expertise. Chris Martz of the Committee for a Constructive Tomorrow also described the attribution work as “scientific fraud.” Trump’s post framed the issue as a threat to American energy growth and called for stricter scrutiny of federally funded scientific advice.
