The study was published in the journal Atmospheric Environment. In the new study, we have analyzed 20 years of aviation emissions, up until and including 2018. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000–2018. Aviation accounts for 3.5%
