Prohibiting unauthorized atmospheric geoengineering.

Bill Details
A JOINT RESOLUTION requesting Congress prohibit unauthorized atmospheric geoengineering and weather modification in the state of Wyoming.
GeoLawWatch Bill Summary
This joint resolution is not a law, but instead expresses the Wyoming Legislature’s position on the issue. It requests that Congress consider taking action.
The resolution does not establish new rules or penalties, but suggests the development and potential passage of future laws that would:
- Propose prohibiting the intentional release of chemical, biological, or radiological substances into the air for weather modification, solar radiation management, or environmental engineering unless the state of Wyoming provides explicit consent.
- Suggest restricting the use of unmarked aircraft, drones, balloons, or space-based platforms for geoengineering activities over Wyoming.
- Recommend classifying unauthorised atmospheric geoengineering as a felony, with fines and criminal penalties for each violation. Enforcement would involve cooperation between federal law enforcement and the Wyoming Department of Environmental Quality or other state agencies.
- Officially oppose any federal, international, or foreign-sponsored geoengineering programs over Wyoming airspace if they lack full disclosure, state approval, and public transparency.
Include an exception clarifying that the resolution does not propose banning ground-based or aerosol cloud seeding.
The resolution directs the Wyoming Secretary of State to distribute copies to the President, the President of the Senate, the Speaker of the House, and Wyoming’s Congressional Delegation.
History
HJ0001 was assigned a bill number on December 1, 2025, and is sponsored by the Joint Agriculture, State and Public Lands & Water Resources Interim Committee. Wyoming's 2026 regular session is scheduled to begin February 9, 2026, with introduction deadlines of February 13, 2026, for both the House and the Senate. The bill was prefiled well in advance of the session start, which is common for committee-sponsored measures.
As a joint resolution, HJ0001 expresses the Legislature's position and requests Congressional action rather than creating an enforceable Wyoming law. If passed by both chambers, it will be transmitted to federal officials, but it does not require the governor's signature. The resolution serves as a formal statement of legislative intent supporting future statutory legislation that would actually create the prohibitions and penalties described in the measure.

A JOINT RESOLUTION
for
A JOINT RESOLUTION requesting Congress prohibit unauthorized atmospheric geoengineering and weather modification in the state of Wyoming.
WHEREAS, it is documented that federal agencies, military contractors or private entities acting on behalf of or at the request of the federal government may be engaging in geoengineering experiments, including but not limited to solar radiation management, stratospheric aerosol injection and weather modification by dispersing chemicals or particulates into the atmosphere without public knowledge or consent; and
WHEREAS, such activities are currently allowed without oversight in Wyoming's airspace and may involve substances such as aluminum oxide, barium, stratospheric sulfates or other compounds, with unknown or unreported impacts on human health, livestock, crops, ecosystems and weather stability; and
WHEREAS, the Wyoming department of environmental quality (DEQ) is charged with protecting the safety and quality of the state's air, water and soil, and must be empowered to investigate and stop unauthorized atmospheric contamination within Wyoming's jurisdiction; and
WHEREAS, it is the constitutional duty of state government to safeguard public health, defend private property, protect agricultural integrity and assert state sovereignty over activities conducted within its borders and above its skies under the tenth amendment of the United States constitution; and
WHEREAS, multiple states, including Tennessee and Florida, have now enacted legislation prohibiting geoengineering modifications, and dozens more are considering similar laws to preserve natural climate systems and ensure transparency in all atmospheric activity.
NOW, THEREFORE, BE IT RESOLVED BY THE MEMBERS OF THE LEGISLATURE OF THE STATE OF WYOMING:
Section 1. That the Wyoming Legislature supports the drafting and passage of legislation to:
(a) Prohibit the intentional injection, dispersion or release of chemical, biological or radiological substances into the atmosphere for the purpose of weather modification, solar radiation management or environmental engineering without the express approval of the state of Wyoming;
(b) Ban the use of unmarked aircraft, drones, balloons or space-based platforms to conduct geoengineering modifications over the state of Wyoming;
(c) Make such unauthorized acts a felony offense, encouraging partnerships between the relevant federal law enforcement agencies and the Wyoming DEQ or relevant state law enforcement entities to enforce such felonies, with substantial fines and criminal penalties per violation; and
(d) Formally reject any federal, international or foreign-sponsored geoengineering programs conducted over Wyoming airspace without full disclosure, state consent and public transparency.
Section 2.
(a) That the Wyoming Legislature urges all elected officials, agencies and candidates to support legislation that preserves Wyoming's natural skies, defends individual and agricultural health and asserts constitutional control over state airspace; and
(b) That the Wyoming Legislature does not support the banning of ground-based and aerosol cloud seeding in Wyoming.
Section 3. That the Secretary of State of Wyoming transmit copies of this resolution to the President of the United States, to the President of the Senate and the Speaker of the House of Representatives of the United States Congress and to the Wyoming Congressional Delegation.
