Some contrails can contribute to global warming. Contrails—pure ice clouds (“cirrus”) that form from aircraft exhaust under specific cold conditions—can trap heat in the atmosphere, sometimes creating ...

Contrails are visible lines in the sky behind aircraft that occur when warm jet engine exhaust meets the colder surrounding atmosphere, forming small ice crystals. Most contrails dissipate within ...

Those white vapor trails crisscrossing the sky carry a hidden climate price tag comparable to the damage from jet fuel itself. Research from Chalmers University of Technology reveals that aviation ...

Contrails conjure a sense of something overwhelming and ineffable, as terrifying as it is beautiful. By Kate Folk I spend most days working from home, in my apartment in San Francisco’s Richmond ...

Aviation's climate impact is partly due to contrails—condensation that a plane streaks across the sky when it flies through icy and humid layers of the atmosphere. Contrails trap heat that radiates ...

Since the dawn of commercial jet travel, the uninformed masses have looked up at the skies and assumed the vapor trailing off of airliners was the government covertly spraying chemicals over the ...

Four research figures show how contrails appear in two satellite views (left) and two photographs taken from the MIT Green Building. Aviation’s climate impact is partly due to contrails — condensation ...
