Rainmaker CEO Augustus Doricko: cloud seeding had nothing to do with the Texas floods

Summary

Augustus Doricko, CEO and founder of Rainmaker, is pushing back hard against claims that cloud seeding contributed to the catastrophic Texas flooding that began in the early hours of July 4th. The flooding, driven by remnants of Tropical Storm Barry converging with large mesoscale weather systems, produced an estimated 4 trillion gallons of precipitation over just a few days in an area already designated as flash flood alley. The National Weather Service issued a flash flood warning at 1:00 a.m. on July 4th and declared a life-threatening emergency by 4:00 a.m.

Rainmaker had suspended all Texas cloud seeding operations more than two days before the flooding, both voluntarily and under Texas Department of Licensing and Regulation criteria that require grounding operations when severe weather warnings are issued or soil saturation thresholds are exceeded. The company's last operation before the event was a 19-minute flight on July 2nd, dispersing approximately 70 grams of silver iodide and 500 grams of table salt at 1,600 feet above ground level into two clouds that dissipated within two hours. Doricko argues the quantity of material dispersed is physically incapable of inducing precipitation at anything approaching the scale observed.

All operational records are filed with the TDLR and are publicly accessible, a point Doricko is using to counter viral misinformation that included social media accounts posting commercial airline flight logs as supposed evidence of weather modification activity.

The Legislative Threat

Rep. Marjorie Taylor Greene is proposing federal legislation that would ban all forms of weather modification, including cloud seeding, solar radiation management, and what proponents of the bill characterize as chemtrails. Doricko describes the proposal as conflating a scientifically grounded agricultural technology with baseless conspiracy theories, and argues it would be both disrespectful to flood victims and damaging to U.S. national interests.

Cloud seeding clients in Texas are primarily public municipal entities operating through associations such as the South Texas Weather Modification Association and the West Texas Weather Modification Association, coalitions of counties and farms that use the service to irrigate crops, fill reservoirs, and recharge aquifers including the severely depleted Ogallala. Funding is largely public money directed at drought mitigation.

Sen. Ted Cruz has publicly stated cloud seeding had nothing to do with the floods, putting him in direct opposition to Greene on the issue.

The China Dimension

Doricko frames a federal ban as a strategic mistake given Chinese investment in the sector. China's weather modification budget has risen from $300 million annually to $1.4 billion as of 2025. Beijing is planning to install 100,000 ground-based aerosol generators on the Tibetan Plateau, supplemented by military drones including the Wingong 2, with the stated goal of creating a large-scale snowpack reservoir to feed agricultural basins in southern and eastern China. Doricko argues that banning American operators while China scales aggressively creates a meaningful capability gap.

Scientific Context and Regulatory Gaps

Physical attribution of cloud seeding effects was not scientifically demonstrated until 2017, when advances in dual-polarization radar made it possible to observe cloud microphysics changing in real time during seeding operations. Prior to that, including during Operation Popeye in the Vietnam War, a U.S. military cloud seeding program targeting the Ho Chi Minh Trail supply chain, the effectiveness of deliberate weather modification was largely unmeasurable.

The current federal reporting framework is the Weather Modification Reporting Act of 1972, a 50-year-old statute Doricko considers inadequate. The Government Accountability Office issued a report earlier in 2025 recommending more stringent federal oversight. Doricko's policy position is that the correct response to the Texas controversy is tighter federal regulation, clearer suspension criteria at the national level, and mandatory public data access, not an outright ban.

On the question of defensive applications, Rainmaker does not currently offer severe weather mitigation. The U.S. government previously funded Project Storm Fury, a series of attempts to reduce Atlantic hurricane intensity before landfall, but it was limited by the atmospheric science and sensing technology available at the time. Doricko believes future investment in NOAA, the National Weather Service, and atmospheric research could eventually enable meaningful severe weather mitigation, and that a blanket ban would foreclose that possibility entirely.

For independent verification, Doricko points to NOAA, the National Weather Service, and the National Center for Atmospheric Research as credible third-party reviewers, adding a pointed caveat that their continued funding is a prerequisite for that oversight capacity to function.
