Solar Geoengineering and Misinformation

The Center for International Environmental Law (CIEL) explicitly rejects the 'chemtrails' conspiracy theory, stating that aircraft vapor trails are composed of water vapor and are not related to weather modification or solar geoengineering.

• The 'chemtrails' conspiracy theory incorrectly links aircraft vapor trails to solar geoengineering research and weather modification to gain credibility, despite the theory being unfounded.
• Weather modification, such as cloud seeding to alter rainfall, has existed since the mid-20th century, whereas solar geoengineering consists of speculative technologies intended to address climate change on a planetary scale, with only a few small-scale experiments using ships or balloons.
• CIEL denies any connection to or endorsement of misinformation that associates solar geoengineering or weather modification with aircraft vapor trails, which are actually formed by water vapor from aircraft exhaust.
