Contrails, which heighten the effect of global warming, may account for more than half (57%) of the entire climate impact of aviation. Contrails are water vapour that condenses as ice onto soot ...

From the development of new materials that make airplanes lighter to the exploration of alternative fuels, the aviation ...

Condensation trails or contrails — the white, feathery lines behind airplanes — could have as big an impact on the climate as ...

Explore how contrails (trails left behind jets) impact climate and how sustainable aviation aims to reduce this hidden ...

Whilst contrails have a slightly cooling effect during the day, their warming impact at night is much stronger. Second, contrails can be fairly easily avoided by flying over or under so-called ice ...

Persistent contrails can spread, merge and form aircraft-induced cirrus, which can have a climate-warming effect. Credit: Frank Wagner/Getty Images In an August press release announcing the ...

Contrails and the resulting contrail cirrus only stay in the sky for a few hours. If they have a lower number of ice crystals, their warming effect is lowered immediately. The use of sustainable fuels ...

Contrails that stay in the sky for a few minutes are not very worrisome, he says. "But if they form at night, they'll maybe last a little longer, and at night they can cause a warming effect," he adds ...

with the non-CO2 effects of air travel producing two to four times the impact of carbon emissions, a Greens MEP has said. Clouds forming from condensation trails - known as contrail cirrus ...

These persistent contrails, as they are known, help to reflect solar radiation back to space, which has a cooling effect. But they also block heat from escaping from… Receive a weekly dose of ...
