Contrails have been observed for more than 80 years, since the start of jet powered aircraft. There are photos of contrails from the 1940’s https://nzhistory.govt.nz/media/photo/aircraft-contrails-after-dogfight There may be an increased number of persistent contrails due to higher altitude flights to safe fuel https://www.cbsnews.com/amp/news/aircrafts-contrails-climate-change/
