I guess it’s unintuitive because the contrails only last a few hours, so how could they have any long term effect? But aviation is continuous, so they get replaced quickly, so there’s probably a constant contribution to warming. I’m not sure how the contrail effect interacts with Earth’s increasing cloudiness.
