Mississippi's legislature has recently seen a surge of bills to ban "geoengineering," also known as atmospheric chemical spraying. This issue highlights new political strategies, populist motivations, and the challenges of lawmaking in a divided statehouse.

Bad Strategy and Worse Timing

In 2025, lawmakers introduced three bills (HB788, SB2005, and SB2013) to ban geoengineering. All of them failed in committee on February 4, 2025, without reaching a floor vote. Their failure stemmed from clashes over legislative strategy during a session marked by political turmoil. To understand this breakdown, it's essential to examine the divergent approaches legislators took.

The 2025 bills followed two different and conflicting approaches:

• The "Regulatory Creep" Approach (HB788): Rep. Carolyn Crawford sponsored this House bill that sought to add a geoengineering ban to Mississippi's Air and Water Pollution Control Law. This approach used existing civil penalties of up to $25,000 per day, treating violations as permit issues instead of serious crimes.
• The "Criminalization" Approach (SB2005 & SB2013): These Senate bills, sponsored by Sen. Angela Burks Hill, Sen. Andy Berry, and Sen. Neil Whaley, took a much tougher stance. They created a new felony with strict penalties: a fine of at least $500,000 and a minimum two-year prison sentence. Interestingly, one co-sponsor, Senator Berry, is both a cattle farmer and the Executive Vice President of the Mississippi Cattlemen's Association – roles that could be affected by a total ban on weather modification.

The committee never got to debate the competing strategies. The 2025 legislative session stalled due to what many called a "catastrophic failure of governance," caused by a significant budget standoff between House Speaker Jason White and Lieutenant Governor Delbert Hosemann. With basic state funding at risk, the leadership set aside the less urgent policy ideas. The bills also went to Conservation and Environment committees, which usually handle hunting and water issues, not complex science topics. As efforts to pass a ban stalled, supporters began rethinking their approach for the following year.

The New Strategy Isn't About the Environment

For the 2026 session, supporters have started a new push, including House Bill 552 from Rep. Kimberly Remak. While the committee's strategy is now unified, the bills propose varying penalties, indicating the approach is not fully aligned. The main shift is framing geoengineering as a "bodily integrity" rather than just an environmental issue.

This new framing links the legislation to the larger post-COVID "Medical Freedom" movement. As World Economic Magazine reported, vaccine sceptics and conspiracy theorists are increasingly aligning themselves with anti-geoengineering efforts, with groups that previously fought vaccine mandates now pushing for geoengineering bans. The underlying message connects government overreach on vaccines to perceived atmospheric manipulation.

The clearest sign of this new strategy is in the bills' committee assignments. Unlike the 2025 bills, the 2026 House bills (HB552, HB1083, HB1086, and HB1087) were all sent to two committees: first to Public Health and Human Services, then to Accountability, Efficiency, and Transparency. This move shifts the debate from conservation to personal health, complicating the bills' progress.

The New Bills Are Aggressive, But They Seem Built to Fail

Even with the new framing, a closer look at the 2026 bills shows they are weak in process and seem likely to fail.

• The 2026 bills outline different penalty structures. HB552 and its Senate version, SB2254, maintain the severe penalties from the 2025 Senate bills, requiring at least a $500,000 fine and a minimum two-year prison sentence. In contrast, HB1083 and HB1086 propose softer penalties: fines up to $100,000 and up to five years in prison. The contrast reveals that the House bills suggest lower fines but potentially longer sentences than the Senate versions. The harsher penalties in SB2254 and HB552 function as a 'poison pill' that deters practical lawmakers, underscoring ongoing disagreement over the strictness of the ban.
• The "Double Referral" Trap: Sending the bill to the Accountability, Efficiency, and Transparency Committee is essential because, in the Mississippi House, this step can stop a bill from moving forward. House rules require that a bill pass every committee to which the Speaker refers it, making it much harder for the bill to reach a vote. House leaders use this leverage to let supporters discuss the bill without risking a full chamber vote.

The Ban Would Make Helping Farmers a Felony

A significant and potentially fatal problem is the bills' broad wording. By banning the release of any substance meant to affect the weather, the bills also ban "cloud seeding."

Cloud seeding is a standard weather modification method used in farming to boost rainfall. States like Texas and North Dakota use it to help crops and fight drought. The Mississippi bills do not include any exceptions for agriculture. This mistake puts the bills at odds with powerful farm groups, such as the Mississippi Farm Bureau. The contradiction is evident, especially since one of the prominent supporters of the felony penalty, Senator Andy Berry, is a cattle farmer who might need this technology in the future.

To make things more complicated, scientific models show that some forms of solar geoengineering could help protect crops from the harms of global warming. This finding means a total ban could actually hurt the farmers it is supposed to help.

More Than Just the Weather

The 2026 geoengineering bills are likely to fail due to their harsh penalties and the challenges posed by the double referral process. Still, their introduction and changes show that a rising populist movement is learning how to work within the legislative system.

This debate is about more than atmospheric science. It stands in for broader issues, such as concerns about state rights, distrust of federal agencies, and strong beliefs in personal freedom. The push to ban "chemtrails" is now part of the culture war, mixing doubts about the environment with medical freedom politics. What might this mean for future debates on public health and environmental policy in state legislatures across the country?
