Georgia representative Marjorie Taylor Greene has announced she is introducing a new bill which would tackle “weather modification.”

Writing on X, the Republican politician said she was creating legislation that would make “the injection, release, or dispersion of chemicals or substances into the atmosphere for the express purpose of altering weather, temperature, climate, or sunlight intensity” a felony.

Why It Matters

Some conspiracy theorists claim that the government or secretive organizations are using commercial or military aircraft to release chemicals or metals into the atmosphere, visible in so-called “chemtrails” —the white lines aircraft leave behind in the sky. People have claimed these are used for a range of things from weather modification to mind control.

According to the U.S. Environmental Protection Agency (EPA), the white lines observed behind aircraft are contrails—condensation trails—that form when hot exhaust from jets meets cold air at high altitudes. The EPA states these are a natural result of flight and pose no risk.

Federal agencies, including the National Oceanic and Atmospheric Administration (NOAA), have publicly denied undertaking or planning any weather modification experiments such as those described by chemtrail conspiracy theorists.

In 2024, after Hurricane Helene killed at least 227 people, Greene made several conspiratorial comments and seemed to suggest the then-Democrat controlled U.S. government could control the weather.

In Florida, a new law makes unapproved cloud seeding and other similar activities a third-degree felony, punishable by up to five years in prison or significantly raised fines of up to $100,000. It came into effect on July 1.

Writing on X, Greene said she had “been researching weather modification” and working on a bill, which she said would be similar to the one in Florida that was signed into law by Florida Governor Ron DeSantis in June 2025.

“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,” she wrote. “It will be a felony offense.”

She added: “We must end the dangerous and deadly practice of weather modification and geoengineering.”

In another post she said that Tennessee representative Tim Burchett was a cosponsor.

“No person, company, entity, or government should ever be allowed to modify our weather by any means possible!!” she wrote

What People Are Saying

Writing on X, Florida Democrat Jared Moskowitz mocked Greene, writing: “I’m introducing a bill that prohibits the injection, release or dispersion of stupidity into Congress.”
