SB1432 prohibits geoengineering or climate modification within state borders. Specifically, it bans intentional injection, release, or deployment of any chemicals, substances, or apparatus aimed at altering temperature, weather patterns, or sunlight intensity (e.g., solar-radiation management). The bill also repeals an older chapter on weather modification licensing and reinforces the integrity of Arizona's water resources fund, ensuring collected fees are maintained in trust and used exclusively by the state Department of Water Resources.
The Arizona State Senate passed SB1432 on March 4, 2025 by a vote of 16 to 11. We have assigned pluses to the ayes because this bill affirms state sovereignty and protects public health by banning experimental geoengineering—such as cloud seeding and solar radiation management—within Arizona. These weather-modification practices pose serious risks to ecosystems, climate stability, and individual rights. SB1432 ensures transparency and accountability by prohibiting such activities without public consent, rejecting unconstitutional experimentation promoted by federal and global climate agendas.
