Excluding the orb, what is wrong in the picture ?? Umm.. Since when have engines been placed under the tail wings of a jet plane..That is where the trails are coming from, in my, dont know anything about airplains or atmospheric properties opinion..

How can it be coming from the tail if they start in front of it?
And have you noticed that the trails line up parallel to the engines?
ot
Why do you think this is?

I know where you are coming from, with the distance part.. but them trails are coming out of the arse end of the tail and if that is the case it proves, they (who ever they are, are spraying something)
And your link dont work..
.....I do know that I do not remember seeing them when I was younger like I see them now a days....

And just to demonstrate how that works, on the left is an A-340 with relatively modern high bypass ratio engines, on the right a B707 with older technology low bypass ratio:
The paper that looks at this is here for a fuller explanation.
Edit: The difference is, IIRC, that newer engines will create contrails at altitudes a few hundred feet lower than old engines - so it is quite marginal, but with millions of flights around the world each year even a small % change can equal quite a large number.

On this page is a very clear explanation of why contrails have changed over the years. Stop wasting your lives and move on

So, are you saying, in a somewhat sarcastic manner, that you don't want anyone to "deny ignorance" regarding this nonsense?
Why would that be?
