Current scientific consensus is that contrails are a net contributor to warming (they trap more heat from escaping the atmosphere than they prevent from entering overall) - but it's a complex phenomena that's difficult to model, so studies vary a lot in estimating the magnitude of this effect - from being a fraction of airplane CO2 emissions, to being several time that.

There are both cooling and warming contrails.
