If you are jetting off for an exotic holiday this summer, spare a thought for those you leave behind.
Because it seems that sun-seekers are responsible for leaving the rest of us languishing under grey skies – thanks to the emissions from aircraft engines.
These vapour trails create clouds which, experts claim, can block out sunlight for millions. This is the reason that our skies appeared unusually blue when the Icelandic volcano Eyjafjallajokull was erupting, and all flights over Britain were banned.
Vapour trails create clouds which, experts claim, can block out sunlight for millions
The phenomenon occurs when aircraft fly above 25,000ft, where the air temperature is around minus 30C. This causes water vapour emitted by the engines to crystallise and form the familiar white streaks across the sky, known as contrails.
These can be short-lived. But if there is already a significant amount of moisture in the atmosphere they can linger for hours, as the excess water vapour from the engines tips the surrounding air past its saturation point.
This acts as a catalyst to speed up the natural process of cloud formation. Cirrus clouds – the wisp-like formations seen at high altitude – begin to form around the contrails.
Scientists say these grow into thin layers of cloud and can cover up to an astonishing 20,000 square miles of sky – or about a fifth of the UK.
The level of moisture in the air at high altitudes is unrelated to weather conditions at ground level, which is why it is possible to see contrails on a clear day.
Reading University’s Professor Keith Shine, an expert in clouds, said that those formed by aircraft fumes could linger ‘for hours’, depriving those areas under busy flight paths, such as London and the Home Counties, of summer sunshine.

...BUT, in the comments section, readers are quick to point out the criminal errors -
Mr Oliver Tree , will you please write another article about chemical trails , this time with some good information ?
Also in Italy we have heard about your misleading article. Please try again.
People would like to read SOME TRUTH.
Grazie.These chemtrails will not go away. I phoned the environment agency and the CAA about these 'chemtrails'. Nobody knew anything about them, unusual for a Govmt. agency, that! Geezer at CAA gave me the usual bull about contrails and then asked me if I had any evidence. I told him 20,000,000 internet sites can't all be wrong. Anyone who has young children will be aware of the so-called, 'vomiting sickness' affecting their chidren in the last couple of years, there was none of this when we were young. Article in the Mail a couple of weeks ago spoke of and I quote " THE ANNUAL SICKNESS BUG ". When, in the name of the Lord, did it become annual.
Has anyone noticed that everybody they meet has got a niggling cough that won't go away? Good news for the pharmaceutical companies. Has anyone noticed that they are forgetting things that happened in the last week? has anyone noticed that they are feeling lethargic and in a state of ennui? Has anyone noticed that their Planet is being
...EPIC FAIL!...
