You can go on the internet just about any day and see conspiracy theories about chemtrails. There are those who believe governments are poisoning the population by spraying chemicals out of airplanes. One scientist decided to do a peer-reviewed study after searching the internet for scientific facts about chemtrails and finding none.
Together with a group of other scientists, they produced a peer-reviewed study in Environmental Research Letters that debunks chemtrails. The 77 scientists concluded that chemtrails are actually water vapor known as contrails. Contrails are condensation trails produced at high altitudes as water vapor passes through jet engine propellers, condenses and freezes.
