I have heard the theory a few times that aircraft are responsible for the change in weather patterns of the last decades.
Yet another conspiracy theory?
it’s not an easy theory to test as no one is going to stop all flights just to see if the weather changes. Except that that has happened. After the World Trade Centre attacks, all aircraft in the States were grounded for three days, and indeed there was an anomalous change in the weather cycle.
Depending on where you live, you may or may not be aware of aircraft. I am not near any of the regular air corridors so aircraft are not that common in the skies here. The lack of aircraft would tend to disprove the theory about aircraft forming clouds, but then that is only in my little neck of the woods, and clouds do have a habit of straying in from neighbouring areas.
I was idly messing around this morning when I went into one of my regular sites. Flightradar24 gives a live image of aircraft in the air at any time. It is an impressive site, as it gives details of all aircraft, such as type, call-sign, point of departure, destination and everything apart from what meal is being served.
I took a snapshot of the Atlantic –
Each of those little yellow/orange blips is an aircraft in the sky.
That is one hell of a lot of aircraft, and all of them creating contrails?
It would make you wonder if there is something to the theory after all?
