Longer flights ‘could curb impact of vapour trails’
By Matt McGrath
Large condensation trails in the sky caused by aircraft could be eliminated by re-routing flight paths, say scientists.
Researchers are concerned about the climate change potential of these wispy, man-made clouds.
But a new study suggests that making changes to existing flight routes could curb their warming impact.
Avoiding a major contrail on a flight to New York from London would only add 22km to the journey, experts say.
Contrails are formed when planes fly through very cold, moist air and the exhausts from their engines condense into a visible vapour.
Double-edged cloud
These can be very large in size: they can be up to 150km in length and can last up to 24 hours.
Scientists have been arguing about the climate impact of contrails for many years, as the clouds that they form impact both cooling and warming.
Contrails reflect sunlight back into space and cool the Earth but they also trap infrared energy in the atmosphere, adding to warming. Researchers believe that the warming effect is more significant than the cooling.
Now scientists at the University of Reading have tried to work out how this impact could be reduced by altering the flight paths of long and short haul aircraft.
Previous work has suggested that planes could fly at lower altitudes to limit the trails, but this means burning significantly more fuel and adding to CO2 emissions.
The Reading study attempted to see if the benefits of curbing contrails would outweigh the extra fuel burned if flights were re-routed at the optimum flying altitude.
“You think that you have to do some really huge distance to avoid these contrails,” lead author Dr Emma Irvine told BBC News.
“But because of the way the Earth curves you can actually have quite small extra distances added onto the flight to avoid some really large contrails.”
Flexible flying
The researchers found that short haul aircraft are more fuel efficient and can add up to 10 times the length of the contrail to their journeys and still reduce overall warming potential.
So if a flight from the UK to Spain is predicted to create a 20km long contrail, as long as the plane flew less than 200km extra to avoid it, the overall warming impact would be reduced.
For large planes on longer routes, this reduces to three times the contrail length.
But longer routes over oceans and unpopulated areas, offer more flexibility to minimally alter flight paths.

The researchers looked at large scale contrails that can last for 24 hours
The researchers found that large contrails could be avoided on flights between London and New York by adding just an extra 22km to the route.
“The key things you need to know are the temperature of the air and how moist it is, these are things we forecast at the moment, so the information is already in there,” said Dr Irvine.
“Whether the forecasts are accurate enough to do this is another question.”
On average, 7% of the total distance flown by aircraft is in the type of air where long lasting contrails form. But at present, calculations on the impact of aviation on global warming don’t include them.
The European Union has attempted to include flights in its emissions trading scheme with limited success.
Long haul flights originating or arriving in the EU will be subject to carbon restrictions from 2017. But the Reading team say that these efforts will still miss out on a significant source of warming from aviation.
“The mitigation targets currently adopted by governments all around the world do not yet address the important non-CO2 climate impacts of aviation, such as contrails, which may cause a climate impact as large, or even larger, than the climate impact of aviation CO2 emissions,” said Dr Irvine.
“We believe it is important for scientists to assess the overall impact of aviation and the robustness of any proposed mitigation measures in order to inform policy decisions. Our work is one step along this road.”
The research has been published in the journal Environmental Research Letters.

First of all lets get one thing perfectly clear and that is that the paedophile lair known as the British Broadcasting Corporation is not independent and is in fact the mouthpieces in Britain for MI5 and internationally for MI6 working on behalf of the interests of the City of London and Westminster. This is no different to the Cable News Network being one of the mouthpieces for the Central Intelligence Agency and the U.S. Army.
Now the picture presented within this article is not of a contrail/vapour trail. This picture shows a cloud full of metallic particles such as aluminium, titanium along with barium and a host of other chemicals and foreign bodies. In fact this picture is of a cross SAG where by these are used by military satellites for targeting reasons including scalar feathering.
Real contrails cannot spread and create clouds lasting for twenty four hours only man-made metallic particle aerosoling can achieve this. This program is known as the Stratospheric Aerosol Geoengineering programme run under the U.S. Air Force utilizing the both civil and military versions of the Open Skies treaty. A real contrail would only last around twenty minutes at the most. If you are of the age of thirty years old or higher you should remember this from watching the skies before this aerosol program started. The contrail would be behind an aircraft but the end of the contrail would soon clear and follow the craft. No contrail stays around for hours and forms fake clouds.
Do not believe either that these aerosols are solely to geoengineer the planet Earth. This type of thinking is what they would want you to think if you finally woke up to the facts of what is happening above your head on a daily basis. There is a lot more to all this including covert biological warfare, 3D mapping VTPRE, surveillance and even body & mind manipulation in conjunction with miniature GWEN microwave antennas veiled as cell phone towers. Have you not wondered why these have the capability to pull 50 kilowatts of juice when cell phone towers and their ranges used need no more than 300 watts? What is the extra 49700 watts waiting for? Even for behaviour manipulation you need no more than 2000 watts! There is even talk of some of these having power supplies cable of pulling a whooping 400,000 watts. How strange when all you really need is between 10-20 watts only!
This article by the BBC propaganda deception paedophile network is an attempt to alter your mindset so you think you understand something when you do not. All at a time when more and more are finding out the truth about this evil program. So now the intelligence networks have to get false stories out to cover their backsides knowing the first information given someone is usually the one that sticks especially if its from a source they believe is an expert. The only thing the BBC is expert at is lying through their teeth and pushing propaganda to suit the fascist state.
By the way the majority of these aerosols are sprayed from military controlled aircraft flying illegal flight paths. If commercial aircraft followed those flight paths they would be grounded. Commercial aircraft also now spray these compounds but still the majority are military controlled. Since they’ve been up in the sky we have had weather warfare actions as well as dimming of the sunlight leading to bacteria, fungus and virus issues not to mention the crop damage from over alkalized soils and a 40% drop in solar panel output. Then we have the impact on health with an expected one billion people as collateral damage according to the World Health Organization so that is a whopping one seventh of the world’s supposed population.
