| SSB3010 | A bill for an act relating to the prohibition of geoengineering activities, providing penalties, and including effective date provisions. | Immediately | Introduced | |
| Iowa's SSB 3010 proposes felony penalties for weather modification activities, with the Department of Public Safety empowered to issue cease-and-desist orders carrying court-enforceable authority. The bill's unusually broad definition of prohibited activities extends beyond typical geoengineering bans to include electromagnetic fields, sound waves, and light pollution when conducted with the intent to alter weather. |
