Geoengineering and weather modification; prohibit certain acts related to.

HB 1086 prohibits intentionally using chemicals within Mississippi to alter weather, temperature, or sunlight intensity through methods like injection, release, or dispersion. Violations carry felony penalties, including fines up to $100,000 or up to five years in prison for most individuals or businesses, with reduced penalties for aircraft operators. The bill requires public infrastructure operators (like airports) to report on aircraft equipped for such activities starting October 2026, and mandates public reporting mechanisms for observed violations. It also references existing air and water pollution laws (Mississippi Code Sections 49-17-5 et seq.) for potential future updates.
