Modern fuel-efficient jets can cause more warming than older planes | News World

The findings could help airlines work out which routes to fly to minimise contrails, says Edward Gryspeerdt at Imperial College London. “If we could predict the contrail-forming regions of the atmosphere well enough, you could route aircraft around them, which would reduce this effect.”

In some conditions, the soot particles emitted by jet engines can seed the formation of ice particles in the wake of aircraft, forming clouds known as contrails that have…
