Most of us first spot them as children—the white lines in the blue sky that are the telltale sign of a flight overhead. Contrails are an instant visual reminder of air travel, and a source of much ...

Sometimes contrails can be seen, and sometimes they can't. The reality of why this is the case is actually simpler than it ...

The contrail clouds formed by jet engines contribute to global warming. In-flight measurements of the particles emitted and contrails produced by a passenger jet show that contrails are formed through ...

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 ...

Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found. The result means that although modern planes emit less ...

Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails ...

Aviation is responsible for about 2.5 percent of global CO2 emissions, but its overall contribution to climate change is higher because of non-CO2 impacts such as contrails. New aircraft may be ...

ALBANY, N.Y. (April 14, 2026) — Fangqun Yu, a senior research faculty member at the University at Albany’s Atmospheric Sciences Research Center, has been studying the microphysics of contrail ...

Altering the altitudes of less than 2% of flights could reduce contrail-linked climate change by 59%, says a new study. Aircraft contrails -- the white streaks aircraft leave in the sky -- could be as ...
