    And those clouds, being too thin to reflect sunlight but able to trap heat, form a kind of blanket around earth, greatly contributing to global warming.

    If I understand it correctly, you could magic away the exhaust and have perfectly clean contrails, and they would still warm the planet.

      Close, the visible parts do reflect sunlight, but what gets through still gets trapped by the greenhouse gasses. You can see the effect in the aftermath of the mass grounding of aircraft on 9/11. There were crystal clear skies and a relatively large jump in temperature compared to just before and after the grounding.
