This should be some interesting reading for you if you haven't read it already: Some scientists believe that from the days after 9/11 (when everybody was grounded) that planes and their pollutants actually have a cooling effect on the planet; they reflect sunlight more into space.

I did read that at the time, and it is interesting. But as James Lovelock says - one of the first people to alert us about rising co2 - smoke or soot is the only countermeasure we have now, but it is a very short term fix and the other gases mixed with it lead to rapid longer term warming.

Water vapour from planes (contrails) have a complex effect and is not yet fully understood see:
