This bill prohibits governmental entities in Texas from engaging in geoengineering, weather modification, and cloud-seeding operations. The bill defines geoengineering as the intentional injection, release, or dispersion of chemicals, chemical compounds, substances, or apparatus into the atmosphere with the express purpose of affecting temperature, weather, or sunlight intensity. The legislation modifies the Agriculture Code to remove previous provisions that allowed governmental entities to conduct or cooperate in weather modification activities. It also narrows exemptions from licensing and permit requirements to focus on private institutions, higher learning institutions, and nonprofit research organizations, removing references to state and federal agencies. The bill repeals several sections of the Agriculture Code related to weather modification and specifies that the changes will only apply to contracts entered into on or after the effective date, which is September 1, 2025. This appears to be a measure aimed at preventing government intervention in weather and climate through technological means, potentially reflecting concerns about the potential environmental or ethical implications of such activities.
