A study that looked at aviation’s contribution to climate change between 2000 and 2018 concluded that contrails create 57% of the sector’s warming impact, significantly more than the CO2 emissions from burning fuel. #stopaviationgrowth https://t.co/Z09xc
"Les émissions équivalentes en CO2 basées sur les potentiels de réchauffement planétaire indiquent que les émissions de l'aviation réchauffent actuellement le climat à environ trois fois la vitesse associée aux seules émissions de CO2 de l'aviation."

@FrederickGuy4 There is a lot of uncertainty around it so it depends on the estimate. This study says "Non-CO2 terms sum to yield a net positive (warming) ERF that accounts for more than half (66%) of the aviation net ERF in 2018." so it's more like triple
