Atmospheric science experts agree ‘chemtrails’ is a fantasy

Believers of one conspiracy theory claim that the persistent condensation trails left behind aircraft in the sky—so-called “chemtrails”—are evidence of a covert large-scale spraying operation with sinister intent. A new study aims to debunk that idea by surveying atmospheric chemists who specialize in condensation trails and geochemists working on atmospheric deposition of dust and pollution. Nearly all of them—76 out of 77—said they had not encountered any evidence of secret atmospheric spraying, reports The researchers, who published their findings in Environmental Research Letters, admit they may never convince the most steadfast chemtrail believers, but they wish to build a foundation of objective science to inform the general population so they won’t believe such a “paranoid fantasy.”
