Creates the "Clear Skies Act" prohibiting geoengineering, cloud seeding and other atmospheric interventions, authorizing DNR to investigate violations, and includes penalty provisions

2025 1st Special Session

1 bill · Adjourned sine die
SB15 Sine die

Prohibits any form of environmental manipulation

Senator Moon strips the environmental manipulation ban from his repeatedly-failed "Freedom to Farm Act" and reintroduces it as a standalone two-page bill during a special session - identical definitional language, identical civil-only enforcement, but without the agricultural deregulation baggage that may have doomed previous attempts.

Special session adjourned on Wednesday, June 11, 2025.

2025 Regular Session

2 bills · Adjourned 15 May 2025
HB78 Sine die

Grants the air conservation commission the authority to create standards and guidelines

A minimalist atmospheric modification ban that prohibits intentional weather and climate intervention but punts all enforcement details to the Air Conservation Commission through rulemaking - a sharp contrast to Missouri's sprawling "Freedom to Farm Act" attempts that bundle weather modification bans with agricultural deregulation.

2025 session adjourned 15th May 2025, remained in Emerging Issues committee

SB297 Sine die

Establishes the Freedom to Farm Act and modifies provisions relating to the Governor's emergency powers and agricultural operations as nuisances

Senator Moon's third consecutive attempt at the "Freedom to Farm Act," now entering the 103rd General Assembly with only a date change from its two failed predecessors. The persistent reintroduction suggests either strong constituent interest or the sponsor's personal commitment, but the lack of any substantive amendments after two committee deaths raises questions about prospects for breakthrough.

2024 Regular Session

1 bill · Adjourned sine die
SB1318 Died in committee

Establishes the Freedom to Farm Act and modifies provisions relating to the Governor's emergency powers and agricultural operations as nuisances

A near-verbatim reintroduction of the previous session's failed "Freedom to Farm Act," now sponsored by Senator Moon instead of Senator Carter, with only the licensing cutoff date updated from 2023 to 2024. The weather modification ban remains buried within a broader agricultural deregulation package.

2023 Regular Session

1 bill · Adjourned sine die
SB84 Died in committee

Establishes the Freedom to Farm Act and modifies provisions relating to the Governor's emergency powers and agricultural operations as nuisances

A sprawling "Freedom to Farm" bill that bans weather modification while simultaneously stripping the governor of emergency food control powers and immunising farmers from nuisance suits and product liability claims. The environmental manipulation ban is almost incidental to the bill's broader agenda of insulating agricultural operations from government oversight.
