This bill establishes a legal framework to prohibit geoengineering activities, specifically targeting practices such as cloud seeding and other forms of weather engineering. It defines key terms related to these activities, including "polluting atmospheric activity" and "weather engineering," and outlines that engaging in such practices is classified as a class D felony. The penalties for violating these prohibitions include a cease and desist order issued by the Department of Public Safety (DPS), which carries the weight of a court order, and each day of violation counts as a separate offense, potentially leading to significant fines and imprisonment.

Furthermore, the bill mandates that federal government and armed forces projects must comply with these restrictions. If any federally approved activity is found to violate the law, the DPS is required to notify the relevant federal agency that the activity is unlawful within the state. The DPS also has the authority to refer potential violations to the Iowa Air National Guard if deemed necessary. The bill is effective immediately upon enactment.
