| SB2254 | Mississippi geoengineering ban; enact. | 1 Jul 2026 | Introduced | |
| Mississippi SB 2254 proposes one of the strictest geoengineering penalties in the nation, with a minimum $500,000 fine and mandatory two-year imprisonment for each day of violation, while embedding the prohibition within the state's existing environmental regulatory apparatus rather than creating standalone legislation. |

| HB552 | Mississippi geoengineering ban; enact. | 1 Jul 2026 | Introduced | |
| Mississippi's HB 552 takes an institutional approach to geoengineering prohibition by embedding it within the state's existing environmental regulatory framework under the Department of Environmental Quality. The bill features a notably severe penalty structure with a $500,000 minimum fine and mandatory two-year minimum imprisonment, among the harshest proposed in any state. |

| HB1083 | Geoengineering; prohibit certain weather and temperature modification. | 1 Jul 2026 | Introduced | |
| Mississippi HB1083 criminalises atmospheric modification activities as felonies and creates a public reporting system through the Department of Transportation, but its most distinctive feature is the mandatory monthly airport surveillance requirement compelling all public airports to report the presence of any aircraft equipped with dispersal capability. |

| HB1086 | Geoengineering and weather modification; prohibit certain acts related to. | 1 Jul 2026 | Introduced | |
| Mississippi HB1086 is a textual duplicate of HB1083 filed by a different sponsor, criminalising atmospheric modification as a felony and creating mandatory airport surveillance reporting; the simultaneous introduction of identical bills by Representatives Arnold and Byrd suggests a coordinated legislative strategy to maximise the chances of committee advancement. |

| Status: Referred To Public Health and Human Services;Accountability, Efficiency, Transparency | ||||
| HB1087 | Weather modification and geo engineering; prohibit. | 1 Jul 2026 | Introduced | |
| Mississippi HB1087 is a stripped-down version of the geoengineering prohibition that omits all enforcement mechanisms, criminal penalties, public reporting systems, and airport surveillance requirements found in the companion bills HB1083 and HB1086, effectively creating a symbolic policy statement rather than enforceable law. |
