A conspiracy theory about aircraft vapour trails takes hold on clear summer mornings.
The word "chemtrails" has trended on sunny mornings this summer - but what's the truth behind the conspiracy theory?They are made up mostly of water and are called contrails or vapour trails, but a growing number of people falsely believe they are evidence of something sinister going on.
A surge in conspiratorial thinking following the Covid pandemic along with the summer travel season and clear skies mean the once obscure chemtrails theory is now being promoted by major influencers.Contrails are formed when water vapour and fine soot particulates from burning jet fuel freeze into ice crystals. In low air humidity, the crystals just dissipate. In higher humidity, they persist, and end up creating visible vapour trails over large areas of sky.
High humidity means that vapour trails can last for long periods and become thin layers of cirrus clouds, Met Office meteorologist Aidan McGivern told the BBC. Cirrus clouds are short, detached and hair-like and are found at high altitudes. It is unlikely that any of these purported chemicals in the clouds would even reach ground level because they are at such high altitudes, he said.
