The contribution of global aviation to anthropogenic climate forcing for 2000 to 2018

Strongly over the past decades in terms of activity, with revenue passenger kilometers increasing from 109 to 8269 billion km yr -1 , and in terms of climate change impacts, with CO 2 emissions increasing by a factor of 6.8 to 1034 Tg CO 2 yr -1 . Over the period 2013-2018, the growth rates in both terms show a marked increase. Here, we present a new comprehensive and quantitative approach for evaluating aviation climate forcing terms. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000-2018. Contrail cirrus, consisting of linear contrails and the cirrus cloudiness arising from them, yields the largest positive net (warming) ERF term followed…
