SilverLining Commends EPA’s Release of Information to the Public on Geoengineering and Contrails

Released yesterday, Administrator Zeldin guarantees information and transparency for the public on the atmosphere.

Washington, D.C. (July 11, 2025) — Yesterday, the Environmental Protection Agency (EPA) released new online resources to communicate the agency’s knowledge about the latest science, research and other information on contrails and geoengineering.

EPA’s new online resources explain the phenomenon behind contrails – and related facts and myths – and the current state of science, research and understanding of potential negative impacts of approaches to cooling the Earth by reflecting sunlight back to space, sometimes called geoengineering.

EPA’s release of information joins other US government resources on weather modification and reflecting sunlight to cool the Earth system including the National Oceanic and Atmospheric Administration registry of weather modification activities, the Biden Administration's 2023 report to Congress, the Department of Energy and NOAA joint workshop report on Marine Cloud Brightening and NOAA’s Earth’s Radiation Budget and SABRE program websites.

Kelly Wanser, Executive Director of SilverLining, issued the following statement on the EPA release:

“We applaud the efforts of EPA and Administrator Zeldin to support accurate public information, full transparency and public safety on particles and aerosols in the atmosphere and their potential effects and impacts. 

SilverLining supports strong observations, scientific tools and open information to ensure the public, policymakers and other stakeholders are well informed and able to ensure public safety and atmospheric security. We appreciate Administrator Zeldin’s valuable step forward in public access and awareness.”
