Legislation based around “chemtrail” conspiracy theories was killed by lawmakers, although there’s still a narrowing window for it to resurface. Meanwhile, state funding for cloud seeding, which is at the root of the conspiracies, is moving forward. On the first day of the Legislature’s budget session, lawmakers reviewed dozens of bills. Some didn’t make the cut, including HB 12 Clean Air and Geoengineering Prohibition Act. After being introduced to the House floor Feb. 9 by Rep. Mike Schmid (R-La Barge), the bill failed 24 to 38. … The chemtrail conspiracy theory gained momentum in the Wyoming Legislature during the 2025 session. Several lawmakers, including Schmid, sponsored similar bills that also failed. But they successfully ended Wyoming’s aerial cloud seeding and nixed state funding for ground operations, leaving other Colorado River states to largely foot the bill. … This year’s Omnibus water bill-construction, SF 70, would reinstate some of that funding.
