Make up of airplane contrails
WebIt's now widely accepted that aircraft contrails are made up of small, droplet-sized liquid droplets, ... As a result, some of those contrails may actually produce a cloud after the aircraft has departed. This is absolute bunk (and a very poor reference). The information that is presented is obviously referencing the weight-of-evidence that. Web1 mei 2024 · Contrails contribute about 67% more to aviation’s global warming effects than carbon dioxide emissions, the second-largest contributor, and more than twice that of nitrogen oxides, which are third on the list. That means cutting contrail formation would have the largest and fastest impact on aviation’s global warming.
