HF2310 Died for lack of action

Prior law prohibiting weather modification reenacted, and criminal penalties provided.

Minnesota’s HF 2310 prohibits all weather modification activities and asserts the state’s sovereign claim over its airspace, treating each day of violation as a separate misdemeanor offense. Notably described as “reenacting prior law,” this suggests Minnesota is reviving a previously repealed or expired weather modification ban.

HF4687 Died for lack of action

Harmful atmospheric activity prohibited, and penalties provided.

Minnesota's HF 4687 goes far beyond typical weather modification bans by establishing a felony offence with $500,000 fines, mandating an elaborate citizen reporting system with 2-hour emergency response requirements, setting specific limits on electromagnetic radiation, and asserting Tenth Amendment authority to override federal approvals for atmospheric activities. The bill uniquely requires officials to actively encourage public monitoring and grants immediate cease-and-desist powers with National Guard enforcement authority.
