SB449 Enacting the clean air preservation act to prohibit solar radiation modification, geoengineering, weather modification, cloud seeding and other polluting atmospheric experiments or interventions and creating a crime for violation thereof. Sine die
Kansas SB 449 goes beyond standard geoengineering prohibitions by authorising the Air National Guard to intercept violating aircraft and by making artificial intelligence systems criminally liable. The bill also includes unusual limits on radiofrequency signal strength for communications facilities and completely dismantles the state's 50-year-old weather modification regulatory framework.
