Contrails are produced by aircraft when their exhaust gasses mix with the air that forms cirrus clouds that produce phenomena known as radiation forcing. They contribute to the greenhouse effect and this will triple with 205, a study claim (stock)

Aircraft are worse for the environment than we thought experts predict that their contrails will heat the atmosphere THREE TIMES more than they already do by 2050

  • Contrails are produced by aircraft when their exhaust gases mix with the air
  • They form cirrus clouds that perform phenomena known as radiation forcing
  • They reflect very little sunlight and fall like a blanket around the planet in warmth
  • They contribute to the greenhouse effect and this will triple in 2050

Vapor flow from the rear of an aircraft is a common phenomenon that is synonymous with international travel, but the impact on the environment can be disastrous.

Research has shown that the impact of jet contrails will triple in 2050, with Great Britain as the largest contributor.

Air travel is becoming increasingly popular, but the beautiful trails act as a blanket over the world and fall in the heat.

Air traffic will be quadrupled in 2050 and routes that prefer higher altitudes will cause contrails in the tropics.

But the climate impact due to icy clouds will be strongest over Great Britain, the US and the rest of Europe, as they are the busiest air traffic areas in the world.

Contrails arise when the water vapor from the aircraft's outlet mixes with the air outside and condenses and freezes.

They eventually form & # 39; cirrus clouds & # 39; that contribute to the greenhouse effect by reflecting less sunlight and falling more on the surface, in a phenomenon known as & # 39; radiation forcing & # 39 ;.

WHAT ARE CONTRAILS?

This forms a temporary line in the air that seems to come out of the plane.

They eventually form & # 39; cirrus clouds & # 39; that contribute to the greenhouse effect by reflecting less sunlight and falling more on the surface, in a phenomenon known as & # 39; radiation forcing & # 39 ;.

This acts as a blanket over the planet and retains heat, which contributes to the greenhouse effect.

In 2005, air traffic accounted for around five percent of all man-made radiation forcing – with contrails that contributed most to the influence of aviation.

But the threat they pose to the environment has largely been neglected in schemes to compensate for aviation emissions.

This despite the fact that contrails contribute more to the greenhouse effect than all CO2 emitted by aircraft since the start of aviation.

Main author Dr. Lisa Bock from the Institute of Atmospheric Physics, Bavaria, said: & # 39; It is important to recognize the significant impact of non-CO2 emissions, such as contrailcirrus, on the climate and to take these effects into account when setting up emission trading systems or schemes such as the Corsia agreement. & # 39;

The Corsia scheme was set up by the United Nations (UN) to tackle CO2 emissions from the aviation sector.

It hopes to compensate all carbon emissions from 2020, but does not mention the damage caused by contrails.

The study, published in Atmospheric Chemistry and Physics, states that contrails can no longer be ignored.

Dr. Dr. Bock and lab colleague Ulrike Burkhardt predicts that the contrails will rise faster than the increase in CO2 radiation forcing as a result of existing measures to increase fuel efficiency.

But it is unclear exactly how great their effect on surface temperature and possibly on rain and snow as a result of the changes in the clouds is, says Dr. Burkhardt.

Dr. Bock added: & # 39; There are still some uncertainties regarding the overall climate impact of contrailcirrus and in particular their influence on surface temperatures because contrailcirrus itself and their effects on surface are research themes. But it is clear that they heat the atmosphere. & # 39;

A possible way to reduce the impact of condensation tracks is to prevent them in the first place.

This can be done by cutting away the soot that is thrown out of the outlets, thereby stimulating them to form.

But this is unlikely to be effective, the researchers claim, and would not be enough to limit global warming to 2005 levels.

Re-routing flights to avoid regions that are particularly sensitive to the effects of contrail formation have also been suggested.

WHAT IS THE THEORY OF CHEMTRAILS COMPOSITION?

Conspiracy theorists have claimed that the long-term condensation traces, or contrails, aircraft left behind are evidence of a secret large-scale spraying program.

They call these fantasies & # 39; chemtrails & # 39 ;.

Supporters of this conspiracy theory sometimes attribute this alleged spray to the government and sometimes to industry.

The chemtrail theory states that the traces of aircraft consist of chemical or biological agents.

Supporters of this idea believe that chemtrails are intentionally left by the US government to control and change the weather.

Researchers have previously carried out a study of the largest atmospheric scientists in the world, who categorically rejected the existence of a secret spray program.

The survey results show that 76 of the 77 participating scientists said they had not come across any evidence of a secret program.

They agree that the alleged evidence cited by those who feel that atmospheric spraying is occurring can be explained by other factors such as the formation of typical aircraft contrails and poor sampling of data.
