Contrails are trails of water vapor left by passing planes and have existed since jets have existed. They are more common than they used to be because commercial jet flights have quadrupled since 1980 and doubled since 2000. https://www.iea.org/data-and-statistics/charts/world-air-passenger-traffic-evolution-1980-2020 https://www.weather.gov/fgz/CloudsContrails https://earthobservatory.nasa.gov/images/78154/the-evolution-of-a-contrail https://www.spartan.edu/news/trails-in-the-sky-all-about-contrails/ https://www.space.com/what-are-contrails
