Contrails trap heat in the atmosphere, which in turn warms the planet. Private jets, already heavily scrutinized for high carbon emissions, represent a big part of the contrail problem.

It says that persistent contrail clouds disturb the atmosphere’s energy balance by preventing heat from escaping back into space. To address this, Google has joined forces with American Airlines in a ...

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 ...

All Nippon Airways Boeing 787 Dreamliner aircraft as seen flying to Paris CDG airport in France in the blue sky over Europe at 40.000 feet leaving the chemtrails or contrails behind, a vapor ...

Look up into the sky on any given day, and you may see one or two contrails—white lines formed when a hot jet engine meets ...

Jet contrails are usually produced at altitudes greater than five miles. However, if conditions during the Winter are extremely cold, they can be produced at lower altitudes.

Contrails form the easiest at altitudes where planes fly the most efficiently because the air is thin. But whether or not a plane makes contrails depends on a variety of factors, including ...

Contrails — those lines of wispy white clouds that follow some jets — may not be so harmless. Airlines and scientists are coming to a consensus that the water vapor trails created by airplanes ...

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 block sunlight, but they also trap heat — even in the dark 2.2 percent of flights create 80% of contrail-related warming — takeoffs in late afternoon and early evening that leave ...
