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 ...

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 ...

Contrary to what some people seem to believe, contrails are not a way for the evil governments of the world use to poison us. They can, however, be harmful to the environment, with some studies ...

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.

If you look up in the sky during a sunny day, you might see long, skinny looking clouds coming from behind planes. Those are contrails, short for ‘condensation trails.’ Airplane engines produce them ...

An e-mail from Jose asks about the term ``contrail'' and wonders if these have any effect on our weather. The word contrail is really just a contraction for condensation trail, which is that cloud ...
