Contrails contribute to climate change, but slight changes in aeroplane altitude can reduce their impact siloto/Shutterstock
Aeroplanes could avoid forming planet-warming contrails by adjusting their altitude 鈥 in many cases, by just a few hundred metres. This could be one of the easiest ways to reduce the climate impacts of aviation.
鈥淚gnoring the contrail question would be silly,鈥 says at the Delft University of Technology in the Netherlands.
Aviation makes up a small but growing share of the emissions that drive global warming. As much as comes in the form of 鈥渘on-CO2鈥 emissions from aircraft…
