Cheap Fix Floated For Plane Vapor's Climate Damage

Cheap Fix Floated For Plane Vapor's Climate Damage
AmiMoJo writes: The climate-damaging vapors left behind by jet planes could be easily tackled, aviation experts say, with a new study suggesting they could be eliminated for a few pounds per flight. Jet condensation trails, or contrails, have spawned wild conspiracy theories alleging mind control and the spreading of disease, but scientists say the real problem is their warming effect.

'They create an artificial layer of clouds, which traps the heat from the Earth that's trying to escape to outer space,' said Carlos Lopez de la Osa, from the Transport & Environment campaign group, which has carried out a new study on the solutions to contrails. 'The scale of the warming that's associated with them is roughly having a similar impact to that of aviation carbon emissions.'

Tweaking the flight paths of a handful of aircraft could reduce contrail warming by more than half by 2040, at a cost of less than $5.1 per flight. Geography and a flight's latitude have a strong influence on whether a contrail is warming. Time of day also influences the climate effects of contrails. Those formed by evening and night flights have the largest warming contribution. Seasonality is also important -- the most warming contrails tend to occur in winter. 'Planes are already flying around thunderstorms and turbulence areas,' Mr Lopez de la Osa said. 'We will need to add one more constraint to flight planning, which is avoiding areas of contrail formation.'
