Absolutely, take for example the effect of contrails. However, the scientific support for the other effects is qualified by the EU as moderate to weak and the margins of uncertainty are large. According to some, the effect is small, according to others, the effect is a doubling of the impact of the CO2-emissions. A few additional remarks though. If you include other effects for aviation, you must of course do the same for other sources. But, more importantly, even if there were a doubling, this would not affect the choice between modes of transport for intercontinental distances. The only alternative for these routes is passenger ships and these use seven times as much energy per passenger as aircraft do. For continental distances, the alternative is High-Speed Rail. But in most cases HSR uses at least as much energy per passenger as aircraft do and at those distances the relative effect of contrails, for example, is very limited because of the relatively short time that an aircraft flies at the altitude at which contrails can arise in certain circumstances.
