Contrails – short for condensation trails – are linear clouds made up of ice crystals that form behind jet aircraft at high ...

The challenge of addressing aviation’s non-carbon dioxide emissions is receiving greater attention, with the climatic impact associated with tell-tale signs in the sky coming under increased study.

An e-mail from Jose asks about the term ``contrail'' and wonders if these have any effect on our weather. The word contrail is really just a contraction for condensation trail, which is that cloud ...

Four research figures show how contrails appear in two satellite views (left) and two photographs taken from the MIT Green Building. Aviation’s climate impact is partly due to contrails — condensation ...

Airbus is calling for more research into the impact of non-CO2 emissions and how to abate them, as preliminary results from a contrail-reduction study have revealed positive results from flight ...

Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found. Modern commercial aircraft flying at high altitudes create ...

Contrail avoidance could help aviation reduce its climate impact. As Europe’s aviation industry looks toward changes in climate policy, experts hope that detailed analysis of contrail effects will ...

Contrails form when hot exhaust gas from an aircraft’s engine mixes with the cold air at an altitude of about 10 kilometres. In dry air, most contrails dissipate quickly. In cold, humid air, however, ...

In the skies over Hampton Roads it is common to see contrails, cloud-like strips of condensed water left behind by aircrafts at high altitude. Some dissipate within minutes, but depending on the ...

Contrails will likely contribute more than 0.1C to global temperature rise by 2050 unless mitigation measures are taken, researchers warn. Credit: Guy Norris/AW&ST Aviation still has an opportunity to ...
