Back in the early 90’s after the slickster got in office. I worked for a major airline. We were instructed to move the weather stations from field between the airfreight facility and the flight kitchen and to relocate them near the jet bridges that had southern exposures. They had to be closer to the ground as well. Now going from a grassy lot to concrete next to where the biggest aircraft were, that had the hottest APU outlets and exhausts. within a few hours we noticed significantly higher temp changes and less humidity. But they paid us a lot of money to maintain them.

There is absolutely no proof that jet engines, with temperatures over 1000 degrees, heat up the air causing a 'warming' of the atmosphere.
