Short summary

NO_x emissions from aircraft affect the climate indirectly, by changing greenhouse gas concentrations. We explore whether the NO_x emissions from aviation would have a different effect in different potential future climate states, i.e. a high pollution and low pollution case. The three models we use show varied responses for how this background state alters the climate effects of the NO_x emissions. This shows the continuing need to improve our understanding of non-CO₂ aviation impacts.
