Montreal: The white, feathery lines behind airplanes that look like bits of harmless cloud are anything but, warn experts, who say they could have a greater environmental impact than the aviation sector's CO2 emissions.
The condensation trails -- contrails, for short -- are being increasingly studied as scientists work with the industry to find technological solutions to the problem.
Classified as non-CO2 emissions from aircraft, in September they were the subject of a symposium in Montreal organized by the International Civil Aviation Organization, a UN agency.
What are contrails?
Contrails are clouds that form at high altitudes in cold, humid areas called ice supersaturated regions (ISSRs).
