    Airplane contrails are a tricky, and surprising, contributor to global warming

    I was referring to the heating effects but thanks for the other part. I've been wondering about cumulative heat (or whatever the scientific term is). When the planet heats up, it will radiate more heat back out into space but I'm sure that it's more complex then just the temperature...

    The heating effects occur mostly at night when there is no sunlight to reflect.
