Proposed ‘weather control’ bans surge across US states

WASHINGTON - Fake stories saying that atmospheric experiments are triggering natural disasters have led to US states pushing blanket bans on weather modification, which experts say may jeopardise current local scientific programmes and hinder future research.

From recent deadly flooding in Kentucky to the

monster hurricanes of 2024, Americans have amplified increasingly conspiratorial explanations for extreme weather events – even blaming manufactured clouds blocking sunlight for the devastation.

In response, lawmakers are moving to criminalise legitimate scientific experiments in the atmosphere.

In Kentucky, Republican John Hodgson told AFP he introduced a Bill because his constituents “do not want to allow any government attempts to modify the solar radiation or weather”.

But no such government programme played a role in the state’s weather whiplash.

“None of this is government control,” said Mr Shane Holinde, a meteorologist at the Kentucky Climate Centre.

“It is all Mother Nature,” he told AFP of the “roller coaster of a month”.

The severe weather events claimed 23 lives across the state, according to Democratic Governor Andy Beshear.

The actions in Kentucky and other states highlight how misinformation has become entrenched in political discourse, driving legislative efforts in response to conspiracy theories.

Tennessee is the first and only state to have passed such a law, despite witness testimony citing chemtrails – a conspiracy that claims toxic chemicals are being sprayed from aircraft.

Kentucky Bill co-sponsor Steve Rawlings, a Republican, also alluded to them, telling local media his efforts address constituents’ concerns of “streaks in the skies”.

The efforts reflect general confusion over beneficial, small-scale activities, such as targeted cloud seeding programmes in the arid west, and large-scale geoengineering projects that are still decades away from possible implementation.

For example, the text of the Bill targets stratospheric aerosol injection – a futuristic technique that the public knows little about.

Scientists hope the method might allow them to shift the total energy balance between the Earth and the Sun and reduce some of the most blatant effects of climate change, including supercharged floods and storms, but it is currently only at a research stage.

The Kentucky legislation mirrors Bills that have been advancing in Florida and Arizona since the start of 2025.

Professor Edward Parson, who teaches environmental law at the University of California, Los Angeles, said such Bills often seek “to prohibit something that is not happening”.

He warned that as more states consider these laws, people will be misled to believe they are “a sensible, legitimate” issue.

Blanket bans

As global warming makes weather extremes more likely, each new natural disaster brings further pushback against “weather control” from an increasingly loud crowd, including prominent political figures such as Republican Congresswoman Marjorie Taylor Greene.

Blanket bans also run the risk of hindering projects shown to benefit farmers by managing hyper-local precipitation and reducing crop losses from hail.

“These state legislations feel a little bit like a knee-jerk reaction,” said Professor Deborah Sivas, who teaches environmental law at Stanford University, while cautioning that regulation around larger geoengineering experiments may prove necessary on an international scale.

She added that there is “a bigger conversation to be had about if you can do things to manipulate weather patterns” over the ocean or other large shared areas.

Ms Dana Willbanks of Columbia University’s Climate Science Legal Defence Fund is tracking science-silencing initiatives nationwide.

She pointed to a surge of climate-sceptic discourse and censorship at all levels of government since the start of the second Trump administration, down to city councils and school boards.

“We are going to start seeing more and more outrageous Bills,” she said, like bans on weather control. AFP
