On January 23, 2025, the New Hampshire Legislature introduced House Bill 764-FN, also known as "The Clean Atmosphere Preservation Act." This legislative proposal aims to prohibit the intentional release of polluting emissions, specifically targeting geoengineering practices such as cloud seeding, weather modification, and the release of excessive electromagnetic radio frequency and microwave radiation. The bill also establishes penalties for violations of this prohibition.

The primary objective of HB 764 is to safeguard public health, the environment, and the state's economy from the potential harms associated with atmospheric manipulation. The bill outlines that activities like stratospheric aerosol injection (SAI) and solar radiation modification (SRM) can adversely affect human health, agriculture, wildlife, aviation, and state security. Notably, the bill does allow for cloud seeding during catastrophic drought conditions, indicating a measured approach to environmental management.

The bill is sponsored by a bipartisan group of representatives, including Rep. Potenza and Rep. J. Aron, among others, and has been assigned to the Committee on Science, Technology and Energy for further consideration. As discussions progress, the committee will likely address potential amendments and the implications of the bill on existing environmental policies.

Debate surrounding HB 764 may center on the balance between environmental protection and the need for innovative solutions to climate-related challenges. Proponents argue that the bill is essential for preserving New Hampshire's natural resources and public health, while opponents may raise concerns about the limitations it places on scientific research and emergency response strategies.

The introduction of this bill reflects a growing trend among states to regulate geoengineering practices amid increasing public awareness of environmental issues. If passed, HB 764 could set a precedent for similar legislation in other states, potentially influencing national discussions on climate intervention strategies.

As the legislative session unfolds, stakeholders will be closely monitoring the bill's progress, with implications for both environmental policy and the broader discourse on climate change adaptation strategies in New Hampshire and beyond.
