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.

For whatever reason, many weather conspiracy theories have crawled out of the fringes and into mainstream discussions. Over ...

Contrails are the visible lines left in the sky behind aircraft when warm jet-engine exhaust meets the colder surrounding atmosphere, forming small ice crystals. Most contrails dissipate within about ...

Still, claims of weather-control technology, once confined to relatively fringe circles, have gained some traction in the ...

Condensation trails or contrails — the white, feathery lines behind airplanes — could have as big an impact on the climate as the aviation sector's CO2 emissions. Here's why and what we can do ...

Here's what's actually coming out of the exhaust pipe of a typical gasoline-powered car.

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 ...

Policy Watch: From contrails to e-fuels, how a UK-led coalition is helping plot a flightpath to greener aviation By Angeli Mehta July 8, 202410:20 AM PDTUpdated July 9, 2024 ...

Contrails form when soot in jet exhaust attracts water vapor, cools, and forms long-lasting ice crystals. If there is some wind, the contrails will spread out into cloud-like formations, and if it ...

Compared to using conventional jet fuel, the use of a biofuel blend reduces aircraft engine particle emissions at cruising altitude by about 50–70 per cent. Aviation affects the climate as a ...
