Summary

New Information

The Environmental Protection Agency has launched new online resources providing information on contrails and geoengineering amid concerns among some Americans.

Conspiracy theories

The move comes as conspiracy theories about cloud seeding are spreading in the wake of deadly Texas flooding.

Divided reaction

While some hailed the announcement, critics contend it adds to legitimacy to non-factual myths about weather and so-called “chemtrails.”


Full story

The Environmental Protection Agency is working to dispel conspiracy theories about contrails and geoengineering by releasing new online resources on Thursday, July 10. The EPA said the move is to show its commitment to “total transparency” about “legitimate questions” Americans have about the phenomenon.

“Americans have legitimate questions about contrails and geoengineering, and they deserve straight answers.” EPA Administrator Lee Zeldin said. “We’re publishing everything EPA knows about these topics on these websites.”

What information is now available?

The agency published new online information on condensation trails, also known as “contrails.” They describe the science behind them to try to help dispel “myths and misconceptions” about them. The most popular conspiracy theory behind contrails is “chemtrails.” Conspiracy theorists claim the government releases chemicals in contrails to alter the weather, control people’s minds and regulate the population.

The EPA has specifically dedicated a new online tool focusing on solar engineering experiments, which entail cooling the Earth by reflecting sunlight into space through the use of gases such as sulfur dioxide. 

“EPA shares the significant reservations many Americans have when it comes to geoengineering activities,” Zeldin said.

The new online resources explain the science and studies involving geoengineering, including potential drawbacks, such as concerns that it may harm the ozone layer and crops, alter weather patterns and create acid rain.

The EPA’s new tools also offer information on the ongoing efforts of the agency to find and monitor “private actors engaged in such activities.”

The new online pages also provide information on weather modification and cloud seeding, as well as federal and state government efforts.

Announcement receives praise and criticism

Professors who specialize in public policy and reviewed the information called the new EPA resources accurate.

Zeldin also posted the announcement on social media, which drew criticism from some users on X. Many critics on social media said he’s lending credence to conspiracy theorists who have no factual evidence for their claims.

“Some people have ‘questions’ about whether birds are real — will that be your next project? Rep. Don Beyer, D-VA, wrote in a reply on X. “How much taxpayer money will you be spending on this?”

President Donald Trump’s Health and Human Services Secretary Robert F. Kennedy Jr., who has shown support for the chemtrails conspiracy theory, hailed Zeldin’s announcement.

“I’m so proud of my friend Lee Zeldin and President Donald Trump for their commitment to finally shatter the Deep State Omerta regarding the diabolical mass poisoning of our people, our communities, our waterways and farms, and our purple mountains, majesty,” he wrote on X.

The agency’s effort comes as conspiracy theories about the deadly Texas floods continue to spread. One of those claims suggested the mass flooding was caused by cloud seeding, which has been debunked by meteorologists.

Despite not having any evidence that weather manipulation caused the floods, some lawmakers are already proposing legislation to stop it. Georgia Republican Rep. Marjorie Taylor Greene introduced a bill that would ban cloud seeding, citing the floods in Texas as her reason.

Why this story matters

The EPA's release of comprehensive information on contrails and geoengineering addresses public concerns, counters misinformation and reflects ongoing debate over government transparency and scientific communication related to conspiracy theories.

Government transparency

The EPA's publication of all available information is intended to increase openness and address legitimate public questions about atmospheric phenomena.

Science communication

Clear explanations of contrails and geoengineering by the EPA seek to dispel misconceptions and educate the public about established scientific understanding.

Role of conspiracy theories

Persistent conspiracy theories, particularly about chemtrails and weather modification, have prompted both official responses and ongoing public debate, highlighting the challenge of combating misinformation.

Community reaction

Many community reactions appear to focus on skepticism or satire. Some Democrats and social media commentators express frustration or mockery, asking if the EPA’s next project is to investigate whether birds are real. Meanwhile, individuals concerned about chemtrails see the EPA’s effort as overdue, while others accuse the agency of dismissing valid concerns or whitewashing the issue.

Context corner

Historically, weather modification practices like cloud seeding have been used since the 1950s, primarily to enhance precipitation in dry areas. Major government projects such as Project Cirrus and Operation Popeye were conducted decades ago for research or military objectives. Recent efforts to regulate or ban similar practices reflect ongoing public suspicions and state-level legislative activity around weather modification.

Debunking

The EPA's new webpages state that “the federal government is not aware of there ever being a contrail intentionally formed over the United States for the purpose of geoengineering or weather modification,” directly countering widespread claims about “chemtrails.” Scientific consensus described contrails as a normal byproduct of jet engine exhaust in certain atmospheric conditions, with no evidence supporting mass chemical spraying operations.

Bias comparison

  • Media outlets on the left frame EPA Administrator Lee Zeldin’s engagement with geoengineering and contrail theories as legitimizing “crackpot” conspiracies that distract from serious environmental deregulation and public health risks under the Trump-era EPA, employing dismissive language like “chemical nightmare” and “crackpot theories” to evoke skepticism toward right-wing narratives.
  • Not enough unique coverage from media outlets in the center to provide a bias comparison.
  • Media outlets on the right emphasize “total transparency” and laud the EPA’s efforts to “debunk claims” while warning cautiously about geoengineering’s risks, using terms such as “tinker” to inject alarm yet support legislation banning weather modification.
