solar radiation management; prohibition; enforcement

Arizona's HB 2042 forbids intentionally injecting, releasing, or dispersing materials within the state for solar radiation management (modifying atmospheric reflectivity to alter sunlight reaching Earth). It also prohibits public entities like universities or private groups receiving public funds from granting money for developing such technologies. Residents can file complaints with the Attorney General about violations, who will investigate and may seek court orders to stop violations and cover legal costs. The bill directly affects anyone conducting or funding solar radiation management activities in Arizona, including researchers and public institutions.
