Prohibit Geoengineering.

SB 485 prohibits the intentional release of weather-altering techniques like stratospheric aerosol injection (SAI), cloud seeding, or electromagnetic emissions within North Carolina to change temperature, weather, or sunlight. It directly affects entities or individuals conducting such activities within the state, excluding licensed pesticide applications via aircraft. The bill defines "atmospheric modification" broadly to cover these methods and adds a specific prohibition against their intentional use for altering weather or climate. The Environmental Management Commission must create implementing rules, and the law becomes effective upon enactment.
