HJ 1 Wyoming House · 2026 Regular Session

Prohibiting unauthorized atmospheric geoengineering.

This Wyoming legislative resolution requests Congress prohibit unauthorized atmospheric geoengineering (such as weather modification using chemicals or solar radiation management) without state consent. It would ban the release of substances for weather control, unmarked aircraft conducting such activities over Wyoming, and classify violations as felonies with fines. The resolution explicitly excludes ground-based cloud seeding from these restrictions and urges federal action to protect Wyoming's airspace and public health. As a request to Congress, it does not create new state law.
