Feathery white lines of condensation left behind airplanes, known as contrails, add to warming the planet. A new study suggests artificial intelligence could dramatically reduce them.

But this comes at a cost: the higher-flying aircraft are creating more contrails that last longer, worsening the industry's impact on climate change, a new study found.

Condensation trails, or contrails, are long, thin clouds that can form behind airplanes at cruising altitude. They are created by jet engines.

Modern aircraft create "longer-lived planet-warming contrails" than older planes, a new study found.

While contrails are not to be confused with the chemtrail conspiracy theory — which posits that exhaust from airplanes is laced with additives used to control the population — they are ...

A new study allays fears that rerouting flights to avoid forming climate-warming contrails could result in inadvertently making climate warming worse.

Why airplanes leave white streaks in the sky Contrails are a problem, but not how you might think. Lauren Leffer Sep 12, 2024 9:00 AM EDT ...

It would be easy to assume that the commercial aviation industry’s fuel consumption was its biggest impact on the environment. For example, a Boeing 737-800 burns about 5,000 pounds of fuel an ...

The water vapor then condenses and freezes around the soot particles, creating a contrail. Sometimes contrails are short-lived and evaporate quickly behind a plane, or there are none.

American Airlines and Google were able to cut contrails made by jets by more than half during a small trial, a move that could significantly reduce the global-warming footprint of the travel ...

The water vapor then condenses and freezes around the soot particles, creating a contrail. Sometimes contrails are short-lived and evaporate quickly behind a plane, or there are none.

Chemtrails do not exist. An expert told USA TODAY that airplane contrails would not be effective at mitigating climate change.
