Staying on the safe side at this point given the high degree of uncertainty related to these effects.

Lee (et al, 2020) state about that particular uncertainty:

"Uncertainty distributions (5%, 95%) show that non-CO2 forcing terms contribute about 8 times more than CO2 to the uncertainty in the aviation net ERF in 2018".
