No.
While the Arizona Senate did advance a bill that would prohibit solar radiation management, a type of geoengineering, there is no link between this practice and a persistent conspiracy theory involving “chemtrails.” The theory—which has been repeatedly and extensively debunked—posits that plane contrails, caused by freezing water vapor, are actually plumes of toxic chemicals or radiation released to control the weather or humans.
Geoengineering and weather modification are scientific fields that explore the use of technology or chemicals to alter weather or atmospheric conditions, typically for agricultural purposes or to combat risks posed by climate change. Arizona law already requires licenses for weather modification projects.
Another bill introduced in the state House this session aims to broadly ban the study or use of weather modification technologies, despite such interventions remaining largely theoretical. The legislation, backed by Arizonans who believe in chemtrails, would require the state to investigate any reports of geoengineering activity.
