Aeroplanes emit two different types of ‘trails’: contrails and chemtrails.
Contrails:
Spread out then slowly disappear altogether in a few minutes.
They are made of water vapour from burning jet fuel in the engines.
Chemtrails:
Spread out but keep spreading and don’t disappear, leaving white lines many miles long.
Block out the sun - it feels cold in their shadow when they pass overhead.
At best it's geoengineering - trying to manipulate the weather - see the Weather Modification Association below.
The planes do not appear on Flightradar24.com, so are presumably military flights.
The planes are spraying in Europe and the USA, but not it seems in the Southern Hemisphere or the Far East. If it was against the alleged 'climate change', it would be logical to have a worldwide operation.
The true purpose is hidden.
Without knowing what chemicals are sprayed, anything else is conjecture.
