Airlines have tamped down on carbon emissions by flying planes at higher altitudes. But this comes at a cost: the higher-flying aircraft are creating more contrails that last longer, worsening the ...

Contrails — the white line-shaped clouds left behind by planes — pose a particular problem as they are able to trap heat. Julian Stratenschulte/dpa Passenger aircraft contribute significantly to ...

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 ...

In the skies over Hampton Roads it is common to see contrails, cloud-like strips of condensed water left behind by aircrafts at high altitude. Some dissipate within minutes, but depending on the ...

Contrails form when hot, moist jet exhaust condenses and freezes into ice crystals upon entering the cold upper atmosphere.

Contrails are human-made clouds. They are streams of condensation left behind from airplanes and rockets. Exhaust leaves water vapor that freezes into tiny crystals in the cold troposphere.

Chemtrails are real and someone is trying to manipulate us. At least that's what hundreds of Louisiana residents have ...

The white trails left by high-flying airplanes may be a pretty sight in a blue sky, but bomber crews dislike them for good reason: an airplane may look from the ground like an almost invisible speck, ...
