Geoengineering Watch

Geoengineering Watch is a website and activist organization founded by Dane Wigington that promotes theories about large-scale atmospheric manipulation programs allegedly conducted by governments and military organizations. The organization claims these programs involve the deliberate spraying of toxic aerosols into the atmosphere for weather modification and population control purposes.

Established in the early 2010s, Geoengineering Watch serves as a central hub for chemtrail conspiracy theories, which assert that normal aircraft contrails are actually chemical or biological agents being dispersed for nefarious purposes. Wigington and his organization claim these operations are causing environmental destruction, human health problems, and climate disruption.

The organization's website features extensive collections of photographs showing aircraft contrails, atmospheric phenomena, and weather patterns that Wigington interprets as evidence of ongoing geoengineering programs. Geoengineering Watch also produces documentary films, most notably "The Dimming" (2021), which attempts to present scientific evidence for large-scale atmospheric manipulation.

Wigington frequently cites legitimate atmospheric science research about solar radiation management and other theoretical geoengineering proposals as proof that such programs are already being implemented covertly. However, the scientific community has consistently rejected claims that commercial aircraft are being used to spray chemicals into the atmosphere for weather modification or population control.

Atmospheric scientists explain that aircraft contrails form naturally when hot jet exhaust meets cold air at high altitudes, and that their persistence and spread depend on atmospheric humidity and temperature conditions. The visible trails that conspiracy theorists identify as "chemtrails" are composed primarily of water vapor and carbon dioxide, the normal byproducts of jet fuel combustion.

Despite repeated debunking by meteorologists and atmospheric scientists, Geoengineering Watch continues to promote its theories through social media, conferences, and documentary productions, contributing to broader public distrust of atmospheric science and climate research.
