On July 5, 2025, purported screenshots of an X post in which U.S. Rep. Marjorie Taylor Greene allegedly said she would introduce a bill prohibiting "weather modification and geoengineering" spread online. Greene allegedly made the post as heavy downpours caused flooding in Texas, leaving hundreds of people stranded.
Per the screenshots, Greene wrote:
I am introducing a bill that prohibits the injection, release, or dispersion of chemicals or substances into the atmosphere for the express purpose of altering weather, temperature, climate, or sunlight intensity. It will be a felony offense.
I have been researching weather modification and working with the legislative counsel for months writing this bill.
It will be similar to Florida's Senate Bill 56.
We must end the dangerous and deadly practice of weather modification and geoengineering.
The screenshots were real. On July 5, 2025, Greene posted the above on her verified X account. As such, we rate this as a correct attribution.
Greene's post can be seen archived here.
In a follow-up post, Greene wrote: "This is not normal. I want clean air, clean skies, clean rain water, clean ground water, and sunshine just like God created it!! No person, company, entity, or government should ever be allowed to modify our weather by any means possible!!"
It is not clear what exact methods of "geoengineering" Greene is referring to from her post alone but it ties into the popular "chemtrails" conspiracy theory, in which many online think puffy white trails or "contrails" behind airplanes are evidence of various agencies spraying the population with dangerous chemicals. This theory has been widely debunked. The white trails in the sky are made up of water vapor and soot particles from burning jet fuel.
Technology that can severely modify rainfall to create floods currently does not exist. The federal agency National Oceanic and Atmospheric Administration also debunked claims that any scientific invention existed to create and steer hurricanes.
The only weather modification being used by private companies in different states is "cloud seeding," a technique that improves a cloud's ability to produce rain or snow by artificially adding condensation nuclei to the atmosphere, like silver iodide.
We have previously reported that cloud seeding is a well-documented effort to counteract droughts and pollution. It has been utilized around the world, including in Dubai and Pakistan. Cloud seeding has also been erroneously blamed for contributing to flooding in the U.S. and Dubai. Experts agree that its impact on increasing rainfall by large amounts has been overstated while mostly natural causes as well as climate change contribute to flooding.
Greene said her effort was aligned with a Florida bill signed into law in June 2025. The Florida bill makes it illegal for anyone to practice geoengineering and weather modification and imposes a $100,000 fine and a five-year prison sentence. The Florida bill would also target cloud seeding.
Greene herself has previously suggested Democrats can "control the weather." She has also speculated that laser beams from space may have started the 2018 California wildfires, and among the entities behind this conspiracy were former California Gov. Jerry Brown, Pacific Gas & Electric, and Rothschild Inc., an investment firm frequently targeted by antisemitic conspiracy theorists.
