Fact vs. Fiction: Did Rep. Marjorie Taylor Greene Propose a Bill Criminalizing Weather Modification?

Claim via Social Media

In July 2025, social media users shared screenshots of a post allegedly made by U.S. Rep. Marjorie Taylor Greene stating she would introduce a bill to ban weather modification and geoengineering, making it a felony offense.

Explanation

On July 5, 2025, Greene posted on her verified X account that she was introducing a bill to ban “the injection, release, or dispersion of chemicals or substances into the atmosphere” to alter weather, temperature, climate, or sunlight intensity. She stated the bill would mirror Florida’s Senate Bill 56, which Governor Ron DeSantis signed into law in June 2025, banning geoengineering practices such as cloud seeding.

Greene’s position echoes long-standing “chemtrail” conspiracy theories, which claim governments use airplanes to spray chemicals into the sky. In reality, the trails behind jets — called contrails — are water vapor and soot. Claims that severe weather can be manufactured through geoengineering are debunked by scientists and agencies like the National Oceanic and Atmospheric Administration (NOAA).

The only widely used weather modification method is cloud seeding, which involves dispersing substances like silver iodide to encourage rainfall. It’s used to alleviate drought in places like Dubai and Pakistan, but experts agree its effects are modest and not capable of inducing extreme flooding.

Greene has previously promoted fringe theories — including suggesting “Jewish space lasers” caused wildfires — and has claimed Democrats can “control the weather.”

Conclusion

Fact or Fiction? Fact. Greene did propose legislation to criminalize weather modification and geoengineering, referencing a new Florida law as its model.
