In the aftermath of deadly flash floods that swept through Texas Hill Country in July 2025, some people online suggested the storms may have been manufactured through a weather modification technique called cloud seeding.

First reported by the Houston Chronicle, cloud seeding involves releasing silver iodide into clouds to increase rainfall under specific conditions. According to the Texas Department of Licensing and Regulation, it is used in select areas of West and South Texas, typically during dry seasons to enhance precipitation.

No person, company, entity, or government should ever be allowed to modify our weather by any means possible!!” Greene tweeted.
