Marjorie Greene Files Bill on 'Weather Modification': Truth Behind The Conspiracy's Alleged Claims

US Representative Marjorie Taylor Greene has announced plans to introduce federal legislation making weather modification activities a felony offence, despite scientific consensus that large-scale weather control technology does not exist.

The Georgia Republican revealed on 5 July that she intends to prohibit 'the injection, release, or dispersion of chemicals or substances into the atmosphere for the express purpose of altering weather, temperature, climate, or sunlight intensity,' with violations carrying felony charges.

Florida's Senate Bill 56, which served as Greene's template, became law on 1st July 2025, making Florida the second US state after Tennessee to ban weather modification activities.

The Bill, which was signed into law by Governor Ron DeSantis, imposes penalties of up to £73,506 ($100,000) in fines and five years' imprisonment for weather modification activities.

The claim, which weather experts have highly refuted for many years, is part of the Congresswoman's claims to 'dismantle the Democrat-funded weather modification systems' in place.

What is the Bill About?

In a post on X (Twitter), Greene said that through this bill, she aims to 'end the dangerous and deadly practice of weather modification and geoengineering.'

She also stated that her bill is similar to Florida's Senate Bill 56, which was filed by Republican Senator Ileana Garcia, focusing on geoengineering and weather modification activities.

'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 offence,' she posted.

As reported by The Hill, the proposed law would make it a criminal offence for anyone to engage in geoengineering or weather modification, carrying a penalty of up to a $100,000 fine and a five-year prison term.

This punishment would encompass practices such as cloud seeding—an 80-year-old method that involves dispersing small particles, typically silver iodide crystals, into clouds to stimulate rainfall or snowfall, according to the Government Accountability Office.

Inside the 'Weather Modification' Conspiracy

Conspiracy theories about 'weather modification' have claimed that governments or powerful groups secretly control storms, droughts, and other extreme weather events.

Prominent figures like Greene have amplified these claims, suggesting hurricanes can be weaponised to target political regions.

An infamous instance of this was back in October 2024, amidst the onslaught of Hurricane Helene that affected Florida, a predominantly Republican state. In a post on X (Twitter), she claimed that the US government was capable of controlling weather, and that the path of the hurricane was geo-engineered to suppress GOP votes–a claim that has been debunked by experts as well.

'Yes, they can control the weather. It's ridiculous for anyone to lie and say it can't be done,' she posted. As of this writing, the post has already been community noted by X users.

She also previously shared patents from the 19th century and NOAA's' weather modification' database, asserting these prove active manipulation programs, which have been disproven by multiple scientific experts as 'silly, frivolous patents' during that era.

Experts Debunk Weather Conspiracy

The National Oceanic and Atmospheric Administration (NOAA) has repeatedly stated that there is no technology capable of creating or steering hurricanes, emphasising that cloud seeding can only slightly increase rainfall in localised areas.

'No technology exists that can create, destroy, modify, strengthen or steer hurricanes in any way, shape or form. All hurricanes, including Helene and Milton, are natural phenomena that form on their own due to aligning conditions of the ocean and atmosphere,' they stated in a 2023 FAQ post about debunking weather modification claims.

Moreover, climate scientists warn that promoting false narratives about geoengineering erodes trust in legitimate science and emergency forecasts. Meteorologists have also faced threats and harassment as conspiracy theories spread online.

Meanwhile, fact-checkers, including Reuters and PolitiFact, have debunked Greene's references to old patents, noting they do not prove large-scale weather manipulation. Experts stress that misinformation during severe storms poses a significant risk to lives.

Striking Turn of Making Conspiracy to Legislation?

Marjorie Taylor Greene's decision to file a bill criminalising weather modification marks a striking turn in how conspiracy theories can shape real legislation. While the proposed penalties target geoengineering and cloud seeding, scientists warn that such sweeping bans risk stifling legitimate research into climate intervention methods that could help combat droughts or mitigate climate change.

As misinformation gains traction in policymaking, the future of evidence-based climate solutions in the US may face unnecessary roadblocks, complicating efforts to address real environmental challenges with credible science.

Greene's bill represents a striking example of how conspiracy theories can translate into proposed federal legislation, potentially impacting legitimate scientific research whilst addressing non-existent threats.

The proposal faces significant hurdles in Congress, where it would need substantial support to advance through committee review and floor votes, though Greene's ability to generate media attention for controversial legislation has proven formidable in previous sessions.
