Committee adopts amendment and reports bill restricting weather‑modification activities upward to state enforcement

The House Natural Resources Committee on May 14 adopted an amendment and reported House Bill 608 favorable. The bill’s sponsor, Rep. Tanner Coats, said the measure is designed to clarify and limit weather‑modification activities — including cloud seeding and experimental solar‑radiation work — over Louisiana.

Under the amendment the committee adopted, criminal penalties were removed and the Department of Agriculture and Forestry was named to administer civil enforcement; the committee also eliminated language placing enforcement with the State Police. The changed language makes violations subject to civil fines and administrative enforcement rather than criminal prosecution.

Rep. Coats said she introduced the bill after constituent concern about “research” and modifications performed overhead and noted federal research and patents on geoengineering and stratospheric aerosol injection. The sponsor cited a 2005 Office of Science and Technology Policy directive and a 2021 National Academies report as evidence that federal agencies have discussed solar‑radiation modification research and governance.

Several members of the public testified in favor of a statewide prohibition or moratorium. Rafael O’Neil and other members of civic groups urged legislators to bar atmospheric experiments without public consent; they described perceived risks ranging from changes in precipitation patterns to long‑term environmental and health effects. Evangelical and civic group witnesses said federal guidance on research governance does not substitute for state limits and called for clear notice and consent rules.

Opposition testimony included representatives of several industry and business groups that filed cards but did not speak on the record. Representatives of the Nature Conservancy and Louisiana Wildlife Federation had been present at earlier river‑related hearings and were not primary participants in this item. Committee members noted this is a complex area that touches federal research programs, international law and local environmental statutes.

Why it matters: Weather‑modification work — and the more speculative concept of solar‑radiation interventions — are increasingly discussed in federal and academic circles as possible climate‑mitigation tools. Louisiana’s coastline and agricultural production make it sensitive to precipitation and coastal changes, and some citizens told the committee they want explicit state safeguards.

What’s next: The committee adopted the civil‑enforcement amendment and reported the bill favorable. Sponsors said they will work with Agriculture and with technical experts on drafting refinements before floor action and on whether additional cross‑references to DEQ or NOAA authorization are needed.
