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 ...

A new study allays fears that rerouting flights to avoid forming climate-warming contrails could result in inadvertently making climate warming worse. Researchers from Sorbonne Universite and the ...

Airplanes sometimes leave white lines in the sky, called contrails. But what's the science behind why they form, and are they good for the environment?

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 ...
