Feds could end Wyoming’s controversial cloud seeding program for good
A new federal effort could end Wyoming’s cloud seeding program. Congresswoman Marjorie Taylor Greene, R-Georgia, announced Saturday her intention to introduce a bill criminalizing cloud seeding and other “dangerous” weather modification techniques. Cloud seeding involves releasing the chemical silver iodide into clouds. The compound causes ice crystals to form from liquid water within the clouds, in turn leading to rain or snow. The Wyoming Water Development Office began winter cloud seeding programs in 2014 after studying it for several years. The office’s first project was a ground-based effort in the Wind River Range. The office began aerial operations in the Medicine Bow and Sierra Madre ranges in 2018. … Silver iodide is toxic enough to be regulated by the Clean Water Act. However, the effects of the chemical haven’t been scientifically proven, according to the Bulletin of Atomic Scientists. Some studies show the amount of silver iodide to be harmless while others claim there could be effects on marine life from accumulation over time.
