Programs like cloud seeding exist, but large-scale weather control is unproven. Weather modification has been researched and tested for decades. One known method is cloud seeding, where planes release substances like silver iodide into clouds to encourage rainfall. This technique has been used in various countries, including the U.S., to increase water supply or reduce hail damage. However, cloud seeding only influences existing clouds and does not allow full control over weather patterns.
There have been claims and conspiracy theories suggesting that the U.S. government has secretly experimented with large-scale weather control. One often-cited program is Project Stormfury, a government effort from the 1960s-80s that attempted to weaken hurricanes by seeding them with chemicals. The project was eventually discontinued due to inconsistent results.
Another point of speculation is HAARP (High-Frequency Active Auroral Research Program), a scientific facility in Alaska that studies the ionosphere. Some theorists claim it was designed to manipulate weather, but scientists explain that HAARP’s radio waves cannot affect large-scale atmospheric conditions.
While weather modification is a real field of study, there is no verified evidence that the U.S. government—or any other—has developed secret technology to control weather on a large scale. Most known efforts remain limited in scope and effectiveness.
