Cool. Back when I lived in Texas I remember having enjoyed cool water in the Summer and hot water in the Winter. Right now it is 54.3 F and the sky is clear and sunny.

The weather here looks like this

Or at least it did yesterday eveining.

Perhaps you weather experts can tell me how a cloud like this develops as it was far too low to be an airplane contrail and didnt fade away, just sort of stayed there until it spread out.

And anyway, why would it abruptly end just where the city suberbs end and the countryside starts?

Dont tell me Chemtrails have come to England!

Those are Contrails and the consist of water mainly, and CO2.

I thought contrails occurred at high altitude where the cold air feezes the water vapour in the Jet exhaust?, the picture dont do justice to how low these this trail was, and on a warm eveining.
And why did the trail end so abruptly?, the other end of it continued thick and stong as far as the horizon.

Yeah, that is still water along with CO2 although the CO2 isn't visible.

Any combustion reaction has:

Fuel + O2 --> H2O + CO2

Yes N2 uses the activation energy of the jet and becomes NO2 and NO3, so there is some pollution too, but after the oil is used use there won't be anymore being put in the air.

Weather here in Minnesota is 70 F and overcast.
