Passenger aircraft contribute significantly to global warming, primarily due to the large amounts of carbon dioxide (CO2) ...

Condensation trails left by higher-flying, lower-carbon aircraft are proving to be disruptive across North America.

Administrator Lee Zeldin said Thursday that Americans have “legitimate questions” about airplane contrails as his agency launches webpages aimed at combatting misinformation on the topic. Contrails, ...

You've definitely seen them in the sky before, but have you ever wondered how plane contrails form? Typically it's a fairly simple process of condensation from jet engines, but sometimes it's just the ...

A coordinated approach to contrails research and technology development in the U.S. could help enhance scientific understanding, reduce climate-warming contrails, and ensure the nation’s commercial ...

Reducing contrails alone won’t solve aviation’s climate-change problem. Air travel is responsible for about 3.5 percent of human-caused warming , according to the National Oceanic and ...

Contrails warm the atmosphere, said study lead author Lisa Bock, a researcher at the German Aerospace Center, since they can linger in the sky as cirrus clouds that trap heat inside the Earth ...

Clouds formed by the water vapour in the exhaust from jet planes have a small but significant effect on daily temperatures, a new study confirms.

You might not imagine that contrails could have much of an impact on the planet, but science says otherwise. The trails themselves are made up of water vapor that quickly freezes, ...

Contrails, the white trails of cloud that some planes leave in their wake, is one area of great uncertainty. Whether or not they form depends on atmospheric conditions, ...

Contrails—those cloudy tracks laid across the sky by jet planes—have a noteworthy effect on the local climate below, new research shows. A study recently published in the International Journal of ...
