This bill makes nearly all deliberate attempts to alter the atmosphere a federal crime and a civil violation, and it removes existing federal authorizations for those activities. It defines "weather modification" broadly to cover cloud seeding, marine cloud brightening, stratospheric aerosol injection, solar‑radiation management, and similar interventions, then criminalizes the knowing authorization or conduct of such acts under circumstances tied to interstate or international commerce.
Beyond criminal penalties, the bill directs the EPA and FAA to build public reporting systems, gives EPA investigatory authority with interagency coordination and mandatory referral to the Department of Justice, and explicitly bars federal agencies and any recipients of federal funds from authorizing or conducting research or experimentation that constitutes weather modification. The measure therefore collapses commercial, research, and regulatory pathways for geoengineering within U.S. jurisdiction.
At a Glance
What It Does
The bill criminalizes knowingly authorizing or conducting ‘‘weather modification’’ in the United States and treats each injection, release, emission, or dispersal as a separate violation. It assigns civil enforcement to the EPA (in coordination with the FAA), requires FAA aircraft‑reporting and public posting, establishes an EPA public reporting and investigation process, and repeals any federal statute, regulation, or executive order that authorizes weather modification.
Who It Affects
Air carriers operating aircraft equipped with devices that could support atmospheric interventions, academic and private researchers who receive federal funding, companies developing geoengineering technologies, and federal agencies that currently sponsor or permit related research. States and localities that host field experiments will also be affected indirectly by the federal ban and reporting regime.
Why It Matters
The bill would effectively end federally authorized geoengineering activities and federally funded experiments in U.S. territory, shifting a previously technical regulatory question into criminal law. For compliance officers, research administrators, and aviation operators, it creates new reporting obligations, potential criminal exposure, and immediate legal uncertainty for programs already underway or planned.

What This Bill Actually Does
The bill creates a broad federal prohibition on ‘‘weather modification’’ defined to include cloud seeding, geoengineering, marine cloud brightening, stratospheric aerosol injection, and solar‑radiation management. A person who knowingly authorizes or conducts such activities ‘‘in any circumstance described’’ — language that ties liability to interstate or foreign commerce, the use of interstate commerce facilities, transmissions across state lines, U.S. territorial jurisdiction, or conduct that otherwise affects interstate commerce — is subject to the penalties set out in the statute.
Penalties mix criminal and civil exposure. Criminal sanctions reach up to $100,000 per violation, up to five years imprisonment, or both; civil penalties up to $10,000 per violation are available to the EPA in coordination with the FAA.
The bill treats each injection, release, emission, or dispersal as a separate violation and extends liability to entities and to officers, directors, or employees who knowingly authorize or commit violations.On monitoring and enforcement, the FAA must establish a public system for air carriers to report the location and movement of aircraft equipped with components that ‘‘may be used to support weather modification,’’ and post those reports online. The EPA must establish a public reporting portal for suspected violations, investigate reports that warrant review, coordinate with multiple federal agencies to verify activities, and refer confirmed violations to the Department of Justice for prosecution.
That creates a public complaint stream and an interagency investigatory pathway linked directly to criminal enforcement.The bill also repeals any federal statutory, regulatory, or executive‑order authority that authorizes weather modification and expressly bars federal departments, agencies, and any recipient of federal funds from authorizing or conducting research, testing, or experimentation that constitutes weather modification inside the United States and its territories. A set of technical definitions anchors the prohibition, and the law becomes effective 90 days after enactment.
The Five Things You Need to Know
The bill makes ‘‘weather modification’’ a federal crime: up to $100,000 fine and/or up to 5 years imprisonment for each violation.
The EPA may impose civil penalties up to $10,000 per violation and must coordinate civil enforcement with the FAA.
The FAA must establish a system requiring air carriers to report aircraft equipped with components that could support weather modification and publish those reports on its website.
Section 4 repeals any federal statute, regulation, or executive order that authorizes weather modification — a blanket nullification of prior federal authorizations.
Section 5 bans federal agencies and any recipient of federal funds from authorizing or conducting research, testing, or experimentation that constitutes weather modification within U.S. territory.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the statute’s citation as the "Air Quality Act." This is a formal element but signals the legislative intent to frame weather modification as an air quality and public‑health matter rather than a purely research or defense activity.
Prohibition and scope
Makes it unlawful to knowingly authorize or conduct ‘‘weather modification’’ and ties criminal jurisdiction to ordinary federal commerce‑jurisdictional hooks: travel in interstate or foreign commerce, use of interstate commerce facilities, interstate transmissions, activities within U.S. special jurisdiction (including aircraft), or conduct that otherwise affects interstate commerce. Practically, that means operations using interstate transport, cross‑border communications, or U.S. airspace fall squarely within the ban; the subsection’s reach is designed to capture both domestic and many cross‑border activities that interact with U.S. commerce.
Penalties and corporate liability
Sets a dual enforcement model: criminal fines and imprisonment for individuals and civil penalties administered by EPA (with FAA coordination). It treats each injection, release, emission, or dispersal as a separate offense and extends liability to entities and corporate officers who knowingly authorize violations, increasing exposure for organizations running or overseeing atmospheric projects.
Reporting and investigation framework
Requires the FAA to create an air‑carrier reporting system for aircraft fitted with components that could be used for weather modification and to publish those reports; requires the EPA to create a public portal for suspected violations and to investigate reports it deems worthy of review. The EPA may coordinate with a long list of agencies (USDA, DOI, FAA, NASA, NOAA, and others) to verify reports and must refer confirmed violations to DOJ. That design centralizes front‑end detection in public reporting and places prosecutorial decisions with DOJ, while obligating interagency fact‑finding.
Repeal and nullification of prior federal authorizations
Effectively vacates any existing federal statutory authorization, regulation, or executive order that permits weather modification, including licensing or permitting frameworks. This sweeping repeal raises immediate questions about the status of previously issued permits, ongoing contracts, and programs — the text purports to nullify them rather than grandfather or unwind them gradually.
Ban on federally funded research and experimentation
Prohibits any federal department or agency, and any recipient of federal funds, from authorizing or conducting research, testing, or experimentation that would constitute weather modification. The ban reaches both direct agency activity and third‑party work funded by government grants or contracts, effectively cutting federal financial pathways for in‑country geoengineering research.
Definitions and effective date
Provides broad, operational definitions for terms such as cloud seeding, geoengineering, marine cloud brightening, stratospheric aerosol injection, and ‘‘weather modification’’ (which covers injections, releases, emissions, or dispersals that change atmospheric composition or behavior). The statute becomes effective 90 days after enactment, giving a short compliance window for entities and agencies to adjust.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Communities and localities concerned about unregulated atmospheric interventions — the ban reduces the legal pathway for deliberate large‑scale interventions that could produce transboundary impacts. Because the law treats each dispersal as a separate violation and requires public reporting, affected communities gain transparency and potential legal recourse.
- Environmental and climate advocacy organizations that oppose geoengineering will gain a clear legal mechanism to prevent federal sponsorship or authorization of atmospheric alteration, reducing the risk of state‑sanctioned deployment without broad consensus.
- Competitor industries and insurers potentially exposed to liability from novel atmospheric interventions—the repeal of federal authorizations reduces regulatory ambiguity and may limit market entry by firms planning to offer geoengineering services in the U.S.
Who Bears the Cost
- Academic institutions, national laboratories, and private research entities that receive federal funding will lose the ability to pursue in‑country experimental work classified as weather modification; research administrators must withdraw, reconfigure, or relocate projects to avoid violating the ban.
- Companies developing geoengineering technologies and suppliers of related hardware will face immediate commercial disruption; the loss of federal permitting and research contracts narrows viable U.S. markets and raises stranded‑asset risk.
- Air carriers and the FAA must implement new reporting systems and disclosure processes, creating operational, compliance, and potential proprietary‑data challenges; airlines may also field increased public scrutiny and legal exposure if crews or aircraft are implicated.
- Federal agencies (EPA, FAA, NOAA, NASA, USDA, DOI) inherit new investigative duties and interagency coordination responsibilities without dedicated appropriations specified in the bill, creating potential resource and prioritization tensions.
Key Issues
The Core Tension
The bill resolves one policy concern by decisively banning atmospheric interventions — protecting against risky, unilateral geoengineering deployments — but it does so by criminalizing a broad set of activities and forbidding federally funded study, creating a trade‑off between preventing harm and preserving the scientific, emergency‑response, and regulatory capacity to understand or responsibly test those same interventions. Reasonable stakeholders will disagree over whether eliminating the research pathway reduces future risks or forecloses necessary knowledge and tools for climate emergencies.
The bill’s operational effectiveness depends on a few unsettled points. The statutory definition of ‘‘weather modification’’ is deliberately broad and could sweep in activities that are not traditionally thought of as deliberate atmospheric engineering — for example, some types of aerosol releases, agricultural spraying that affects local microclimates, or experimental field work that disperses trace materials.
That breadth gives prosecutors discretion but increases legal uncertainty for researchers and operators trying to interpret whether routine or ancillary activities are now criminal.
Implementation also raises pragmatic problems. Publishing reports of aircraft equipped with components that ‘‘may be used to support weather modification’’ creates transparency but risks exposing sensitive operational data (proprietary retrofits, flight tracks) and could generate a high volume of nuisance reports that strain EPA and FAA resources.
The blanket repeal of authorizations and the prohibition on federally funded research removes formal pathways for regulated experimentation and state or academic collaborations, but it does not address extraterritorial research conducted by U.S. entities or foreign projects that affect U.S. airspace — enforcement against those activities could be legally and practically difficult. Finally, the bill centralizes enforcement in criminal law and DOJ referrals, which may deter beneficial observational research or rapid emergency responses by states or private actors because of fear of criminal exposure.
