Enacting the Kansas geoengineering and weather modification prohibition act, prohibiting geoengieering and weather modification activities, providing criminal penalties for violations of the act and assigning enforcement and reporting authority to the department of health and environment.

HB 2439 prohibits any activity within Kansas that injects, releases, or disperses chemicals, substances, or devices into the atmosphere for the purpose of altering weather, climate, or sunlight intensity. It directly affects individuals, companies, and airport operators who conduct such activities, imposing criminal penalties including fines up to $100,000 for violations. Key mechanisms include requiring public-use airport operators to report suspicious aircraft monthly to the Department of Transportation (which then forwards reports to the Department of Health and Environment), and granting the Department of Health and Environment enforcement authority. The bill repeals Kansas' previous weather modification laws (K.S.A. 82a-1401 through 82a-1425) and takes effect in 2026.
