A state legislative committee failed to pass a bill draft last week that would have placed a 10-year moratorium on all cloud seeding activities in the state. During the moratorium, the Wyoming Department of Environmental Quality would have been tasked with completing a study of cloud seeding impacts compared to baseline conditions, according to the initial bill proposal – but University of Wyoming Atmospheric Science Department Head Jeff French said that plan wouldn’t be “scientifically sound.” … “The only way I could see us actually being able to measure the effectiveness of cloud seeding is by doing a focused study that includes cloud seeding.”
