The gist

Makes weather modification — including cloud seeding and geoengineering — a federal crime, banning all such activities and research across the United States.

Who wins, who loses

Wins: Anti-geoengineering activists, residents suspicious of 'chemtrails,' communities opposing aerial spraying.

Loses: Climate scientists, drought-stricken farmers using cloud seeding, ski resorts boosting snowfall, geoengineering researchers.

What it does

Sets penalties up to $100,000 and 5 years in prison per violation; Environmental Protection Agency (EPA) adds $10,000 civil fines.

Makes company executives personally liable when their firms violate the ban.

Orders Federal Aviation Administration (FAA) to track aircraft with modification gear; EPA runs a public tip line.

Repeals all existing federal weather-modification permits and bans federally funded research; effective 90 days after enactment.

Why should I care?

Supporters say spraying chemicals into the sky without public consent is dangerous and unaccountable, and a hard ban prevents risky experiments. Critics argue cloud seeding has helped farmers for decades, and blocking geoengineering research removes a possible tool against climate change. An alternative being debated is strict licensing instead of an outright ban. Where do you land? Vote below and use "Tell Your Rep" to make sure your voice reaches Congress.
