The warming effects of aircraft vapor trails could be eased with fewer night flights, especially during winter, the report says.

Nicola Stuber, first author of the study, to be published in tomorrow’s edition of the journal Nature, suggests that contrails’ overall impact on climate change is similar in scope to that of aircrafts’ carbon dioxide (CO2) emissions over a hundred-year period.
Aircraft are believed to be responsible for 2 to 3 percent of human CO2 emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet.
However, they also trap energy in Earth’s atmosphere and boost the warming effect, the study says. […]
Contrails are artificial clouds that form around the tiny aerosol particles in airplane exhaust.
They appear only in moist, very cold (less than 40ºF/4ºC) air—usually at altitudes of 5 miles (8 kilometers) or higher.
Some contrails can…
