HB1083 Died for lack of action

Geoengineering; prohibit certain weather and temperature modification.

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.

Last action
HB1086 Died for lack of action

Geoengineering and weather modification; prohibit certain acts related to.

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.

Last action
HB1087 Died for lack of action

Weather modification and geo engineering; prohibit.

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.

Last action
HB1406 Died for lack of action

Geoengineering; prohibit certain weather and temperature modification.

This bill assigns enforcement to the Department of Transportation rather than environmental or health agencies, creates an unusual public reporting system for "chemtrail-equipped" aircraft at airports, and uses funding leverage rather than direct criminal penalties to ensure airport compliance with monthly surveillance requirements.

Last action
HB552 Died for lack of action

Mississippi geoengineering ban; enact.

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.

Last action
SB2254 Died for lack of action

Mississippi geoengineering ban; enact.

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.

Last action
SB2418 Failed

Environmental protection; prohibit geoengineering.

Mississippi's bill takes the regulatory integration approach, embedding a prohibition on geoengineering within the state's existing Air and Water Pollution Control Law and delegating rulemaking authority to the environmental commission, rather than creating standalone prohibition language. The minimum penalties—$500,000 fine and two years imprisonment per day of violation—rank among the most severe proposed in any state.

Last action
SB2666 Died for lack of action

Environmental protection; prohibit chemtrails.

Mississippi's SB 2666 embeds a geoengineering prohibition directly into the state's existing pollution control framework, giving the Commission on Environmental Quality explicit regulatory authority rather than creating a standalone enforcement mechanism. The $500,000 minimum fine and mandatory 2-year minimum imprisonment rank among the harshest proposed penalties nationwide.
