The challenge of addressing aviation’s non-carbon dioxide emissions is receiving greater attention, with the climatic impact associated with tell-tale signs in the sky coming under increased study.

Sometimes contrails can be seen, and sometimes they can't. The reality of why this is the case is actually simpler than it ...

The National Academy of Sciences, Engineering, and Medicine will convene a committee to develop a national research agenda to understand better, quantify, and support the development of technical and ...

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 ...

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 ...
