Geoengineering now a criminal offense in Florida as Attorney General issues stern letter to airports outlining strict reporting rules and legal consequences
Florida – Florida Attorney General James Uthmeier has told all public-use airports in the state that they must properly follow a new legislation that bans weather modification activities. Governor Ron DeSantis signed the law on June 20, and it formally went into effect on July 1. It is one of the strictest of its kind in the country.
Senate Bill 56 makes it a crime to intentionally release any chemical or substance into the air to alter the weather, sunshine, or climate. If someone breaks the legislation, they might face fines of up to $100,000 and even prison time.
The law not only bans these kinds of activities all around the state, but it also directly limits airplanes. Florida’s public-use airports now won’t let any planes that are set up to change the weather, such as those employed in cloud seeding operations, land, take off, refuel, or even stop. Beginning on October 1, airport operators must send the Florida Department of Transportation (FDOT) monthly reports that list any aircraft capable of performing weather-related alterations.
Uthmeier made it clear that this strategy is not only for show. He made it plain in his announcement that there will be penalties for not following the rules. He told airport officials that enforcement would be quick and strict, and any airport that broke the rules may lose state money. The Attorney General also said again that the state is committed to working with FDOT, the Florida Department of Environmental Protection, and local law enforcement to enforce the law.
Uthmeier highlighted the risks of geoengineering technologies, saying they may expose people to dangerous particles and contaminate farms. This stems from growing concerns about environmental health and food safety. He also mentioned recent flash floods in Texas as part of a larger warning, but experts have pushed back against claims that cloud seeding might cause such bad weather.

The FDOT’s compliance guideline from July 11 has been sent to airport operators, who have been told to read it and make sure they fully understand the new Florida laws. The Attorney General’s Office has made it clear that Florida will not tolerate any actions, whether deliberate or not, that get in the way of natural weather systems.
This is the full letter:
Dear operators of Florida public-use airports:
On June 20, 2025, Governor Ron DeSantis signed Senate Bill 56 into law, which prohibits geoengineering and weather modification activities within the State of Florida. As Florida’s chief legal officer, I write to ensure you are aware of and comply with your new obligations under this law.
As of July 1, 2025, section 403.411(1), Florida Statutes, prohibits “the injection, release, or dispersion, by any means, of a chemical, a chemical compound, a substance, or an apparatus into the atmosphere within the borders of this state for the express purpose of affecting the temperature, weather, climate, or intensity of sunlight.” Violators of this law are guilty of third-degree felonies and fines as high as $100,000.1
This landmark legislation marks another Florida victory for health, freedom, and environ- mental protection. From farmlands to our waterways, to the very air we breathe-Floridians’ health is under attack from toxic particulates being sprayed into our atmosphere, polluting our water, contaminating agriculture, and destroying human health. Injecting our atmosphere with novel chemical compounds to block the sun is a dangerous path, especially in Florida, where sunshine is our most valuable resource. Furthermore, as our hearts break for the victims of the flash floods in Texas, I can’t help but notice the possibility that weather modification could have played a role in this tragedy. Developing reports show that a weather modification company conducted “cloud seeding” operations just days before the deadly flood.2 Florida’s new law seeks to prevent something like that from ever happening.
In addition to banning these dangerous experiments, section 403.4115, Florida Statutes, goes even further and requires all “public-use airports” to report on geoengineering and weather modification activities. Starting on October 1, 2025, all operators of public-use airports must submit monthly reports to the Florida Department of Transportation (“FDOT”) that include the following: (1) the physical presence of any aircraft on public property, including any public-use airport, equipped with any part, component, device, or the like which may be used to support the intentional emission, injection, release, or dispersion of air contaminants into the atmosphere within the borders of Florida when such emissions occur for the express purpose of affecting temperature, weather, climate, or the intensity of sunlight; and (2) the landing, takeoff, stopover, or refueling of an aircraft equipped with the components outlined in requirement (1) on the physical location of a public-use airport.4 Failing to comply with your new reporting obligation could result in a loss of state funding.5
Because airports are most likely to catch those who seek to weaponize science in order to push their agenda, your compliance with these reporting obligations is essential to keeping our state safe from these harmful chemicals and experiments. We need your help to keep our state free and make sure the skies belong to the people-not to private contractors, corporate experiments, or climate extremists. In Florida, we don’t jeopardize the public health so that we can bend the knee to the climate cult.
My office will work closely with FDOT, the Department of Environmental Protection, and Florida law enforcement to enforce this new law and your obligations to the fullest extent possible. Consequently, you should further familiarize yourself with these laws to ensure compliance and you should look to the FDOT for further guidance on your reporting obligations. To that end, I refer you to the FDOT implementation update you received on July 11, 2025, which provides relevant guidance. We look forward to your compliance and cooperation.
