21 April 2026 | ZEROGeoengineering.com | Report published by California Department of Water Resources recommends continuing cloud seeding programs which have been ongoing since the 1950’s. Recommended strategy includes support of research experimentation on new seeding agents and “cloud physics and cloud modeling being done by the NOAA labs and academic institutions.” Acknowledged is the FACT that scientific validation of increased water supply due to cloud seeding is unconfirmed. According to the document, silver iodide is the active seeding agent, supplemented by dry ice for aerial seeding. NOTE: dry ice is solid carbon dioxide (CO2). 

“…provide mechanisms for funding, and collaborate with the federal partners to conduct additional research and development in California…”

“The State should support research on potential new seeding agents…”
