Just because the contrails are science

I understand that part, doesn't stop them from containing the plane exhaust which is directly contributing to global warming

Well, it's not jet exhaust you're seeing, though.

I did acknowledge that, by the way. Jet fumes certainly contribute to global warming. I wasn't intending to imply they don't. Simply that it's not jet fumes you're seeing in contrails.

I will convolute this conversation further by stating that contrails (like all other clouds consisting of ice crystals) warm up the planet by letting shortwave radiation from the Sun through while being more reflective in longer infrared wavelenghts, thus trapping outgoing longwave radiation. Contrails themselves are also warming the planet up. It's a small contribution in the grand scheme, but far from a trivial one.
