Curb night flights to preserve climate

RESTRICTING the number of night-time aircraft flights could help to fight global warming as well as make life easier for people living near airports.

A study has shown that the condensation trails, or 'contrails', left by aircraft engines' exhausts can exacerbate global warming more when they are produced at night than during the day.

The scientists behind the study, which was published in the journal Nature, said the results suggested that rescheduling flights for the daytime could help to minimise the impact of aviation on climate change. The scientists at Reading University used computer models of contrail data to show that, even though only one in four flights over Britain occurred at night, the night-time flights were responsible for about 60pc of the climate warming associated with the contrails.

Burning jet fuel produces large amounts of carbon dioxide. I don't think think 'contrails' are a significant factor.

Cutting down on the number of flights would help reduce global warming. Moving flights from night time to day time would have very little effect, IMHO.

Most night flights are cargo haulers (UPS, DHL, FedEx, etc)...and there are a LOT of them.

Push those flights to daytime hours and you'll see air traffic delays that will make sitting on a taxiway a Newark for an hour look like a picnic.
