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.

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 ...

Nudging aircraft onto slightly different paths to avoid contrail formation could slash climate warming due to aviation over the next 25 years almost in half, according to a new study. The analysis ...

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 ...

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

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 ...
