Disinformation around a “weather weapon” and cloud seeding is being widely promoted by everyone from anti-government extremists to GOP influencers—leading to real-world consequences.

Republicans, including Georgia Rep. Marjorie Taylor Greene, have accused the scientific practice of being used to harm and kill, with Greene proposing a bill on Saturday that would make weather modification, also called cloud seeding, a felony.

Along a similar vein, conspiracy theories maligning Doppler weather radars as “weather weapons” have heightened in the wake of flash floods in central Texas. Forecasters use the radar system to detect precipitation, and now have to worry about vigilantes vandalizing them at times when people rely on those forecasts to stay safe.
