Congressional Hearing
September 2025"Playing God with the Weather — A Disastrous Forecast"
House Subcommittee hearing with three expert witnesses under sworn testimony. Dr. Pielke testified that weather modification has been practiced for 70 years without knowing if it works.

Full hearing summary →GAO Oversight Report
February 2026GAO-26-108013 — "Weather Modification: NOAA Should Strengthen Oversight"
The government's own auditor found that NOAA's oversight is broken: 78% of filed reports contain errors, 4 of 10 states had unreported activities, reporting forms haven't changed since 1974, and NOAA has never issued a single fine in 50+ years of authority. This report is fuel for every pending state bill.
