Geoengineering; prohibit certain weather and temperature modification.

HB 1083 prohibits intentionally releasing chemicals into Mississippi's atmosphere to alter weather, temperature, or sunlight intensity. It directly affects public infrastructure operators (like airports) and any individuals or entities conducting such "geoengineering" activities. Key provisions require public infrastructure operators to report aircraft equipped for atmospheric modification starting in 2026, impose felony penalties (up to $100,000 fines or 5 years in prison), and establish a reporting system for violations. The bill also references existing air pollution laws to clarify enforcement but does not create new environmental standards.
