Turns Out We Might Need to Worry About Airplane Contrails - But Not For Those Reasons

sciencealert.com
  • Carbon isn't the only environmentally harmful airplane emission - turns out that condensation trails forming in the sky during flight have a warming effect as well.
  • Contrail cirusses, frozen clouds of ice crystals created from jet exhaust moisture, have larger radiative forcing than airplane carbon emissions.
  • New study forecasts that the way air travel is growing, the warming effects of contrails might triple by 2050.
  • However, long-term warming effects of contrails last shorter compared to carbon - a few decades compared to thousands of years.
  • It still shows that there are more aspects to the harm that air travel does to the environment, and they are worth investigating.
