| HB2042 | Solar radiation management; prohibition; enforcement | 24 Jul 2026 | Introduced | |
| Arizona HB 2042 prohibits solar radiation management activities and establishes a citizen complaint system requiring the Attorney General to investigate "credible" allegations, with enforcement limited to civil injunctive relief rather than criminal penalties or monetary fines—a notably restrained approach compared to other states' weather modification legislation. |

| 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. |

|
||||
| Graphic | ||||
| HB1618 | Prohibiting solar radiation modification, weather modification, and other polluting atmospheric interventions. | 1 Jan 2027 | Introduced | |
| New Hampshire's HB1618 creates an aggressive enforcement regime against atmospheric interventions involving pollutants, establishing a citizen deputy system where county sheriffs must deputise volunteers to help enforce felony prohibitions carrying minimum $500,000 fines, while simultaneously empowering the Air National Guard to interdict aircraft and imposing strict electromagnetic radiation limits on communications facilities—making artificial intelligence entities themselves subject to criminal prosecution. |

| HB1128 | Restricting the use of weather modification technologies to declared emergencies. | 60 days | Introduced | |
| Rather than prohibiting weather modification outright, New Hampshire's HB 1128 takes a permissive, emergency-only approach, allowing cloud seeding during declared catastrophic droughts, subject to environmental review and extensive public disclosure of chemicals and impacts—a regulatory framework that contrasts with the complete bans pursued in other states. |

| Graphic | ||||
| A05476 | Prohibits the intentional injection, release or dispersion, by any means, of chemicals, chemical compounds, substances or apparatus within the borders of this state into the atmosphere with the express purpose of affecting temperature, weather or the intensity of sunlight. | Immediately | Introduced | |
| New York's A.5476 takes a minimalist approach to geoengineering prohibition, establishing a ban on intentional atmospheric releases designed to affect temperature, weather, or sunlight intensity but providing no enforcement mechanism whatsoever—not even a penalty structure for violations. |
Last update Wed 7 Jan 2026 |

| S08529 | Prohibits the intentional injection, release or dispersion, by any means, of chemicals, chemical compounds, substances or apparatus within the borders of this state into the atmosphere with the express purpose of affecting temperature, weather or the intensity of sunlight; provides the department will establish a reporting process for violations; provides penalties for such violations. | Immediately | Introduced | |
| New York's S.8529-A goes far beyond simple prohibition by establishing a dual surveillance system requiring mandatory monthly aircraft monitoring by all public infrastructure operators and a citizen reporting portal, backed by class E felony charges that expose corporate officers to up to 5 years' imprisonment. |

Ohio (2025-2026 Regular Session)
Session Adjourn Thu 31 Dec 2026
|
||||
| Graphic | ||||
| HB290 | Enact the Atmosphere Protection Act | 90 days | Introduced | |
| Ohio's "Atmosphere Protection Act" imposes some of the harshest penalties in state weather modification legislation—a mandatory 3-year prison term and a minimum $500,000 fine under strict liability, meaning prosecutors need not prove intent. The Legislative Service Commission's own analysis notes uncertainty about what the undefined term "sunlight reflection methods" actually prohibits. |

|||
| Status: Held in Natural Resources since May 2025 | ||||
| HB272 | Regards food dyes, PFAS, fluoride, and certain substance releases | 90 days | Introduced | |
| Ohio's HB 272 buries a straightforward prohibition on weather modification within an omnibus consumer protection bill covering PFAS chemicals, food dyes, and water fluoridation. The atmospheric release provision is notably modest compared to Ohio's other pending weather modification bill (HB 290), imposing misdemeanour penalties rather than felony charges, suggesting different legislative philosophies on enforcement severity even within the same chamber. |

| SB430 | Environment; prohibiting intentional injection, release, or dispersion of chemicals, chemical compounds, substances, or apparatus in this state; repealing the Oklahoma Weather Modification Act. Effective date. | 1 Nov 2025 (invalid) | Introduced | |
| Oklahoma's SB430 is a companion bill to SB1021, using the same prohibition language but taking a conventional criminal penalty approach with misdemeanour charges and a $10,000 fine, rather than SB1021's Air National Guard interdiction authority. |

||||
| Graphic | ||||
| S0110 | Air Quality | Immediately | Introduced | |
| South Carolina's S. 110 is the Senate companion to the minimalist House approach, creating a bare-bones weather modification prohibition without penalties or exemptions—but its referral to the Medical Affairs Committee rather than environmental or agriculture committees signals a unique legislative focus on public health impacts. |
Last update Tue 14 Jan 2025 |
|||
| Status: Held in the Committee on Medical Affairs since Jan 2025 | ||||
| H3083 | Air Quality | Immediately | Introduced | |

| H3915 | South Carolina Clean Air Act | Immediately | Introduced | |
| South Carolina's H. 3915 establishes a mid-tier enforcement approach to weather modification, combining federal-level felony penalties with whistleblower protections for citizens suing the government, while notably omitting the more aggressive airport employee prosecution and bounty provisions found in companion bill H. 4624. |

| H4010 | South Carolina Clean Air Act | Immediately | Introduced | |
| South Carolina's H. 4010 represents the most agriculture-friendly version of the state's weather modification bills, explicitly exempting both cloud seeding and crop dusting operations while notably omitting any criminal penalties or enforcement mechanisms for violations—essentially creating a prohibition without teeth. |
Last update Thu 13 Feb 2025 |

| Tennessee's HB 1112 creates one of the more aggressive enforcement frameworks among state weather modification bills, combining criminal misdemeanour charges with a substantial $100,000-per-violation administrative fine and extending liability up the supply chain to anyone providing materials with knowledge of their intended use.

| SB0723 | AN ACT to amend Tennessee Code Annotated, Title 47, Chapter 18 and Title 68, Chapter 201, relative to weather modification. | 1 Jul 2025 | Introduced | |
| Tennessee's bill takes an unusual enforcement approach by routing weather modification violations through consumer protection law rather than creating direct criminal prohibitions, treating cloud seeding as essentially a form of commercial fraud. The narrow application only to "weather-related companies" makes a significant gap—the same activities would remain legal if conducted by entities outside this defined category. |
