Its 90 degrees here today....
You beat me to it. ^^That^^

How many times must it be pointed out that:
Its 90 degrees here today....
....has absolutely no relevance to contrails?
It is "90 degrees" there (90°F = 32°C). But, that is the temperature at the surface!
It is not difficult at all to find online information about the ambient air temperatures at the altitudes where jets fly, and contrails are formed.
For example, in North America:

Don't waste your time entertaining the deniers here who will glibly take the sight from your eyes and the sense from your judgement.
Why doesn't it happen at night?

This is sickening hundroid, and it seems we are powerless to do anything
about this BS. Don't waste your time entertaining the deniers here who

This is sickening, deadly serious s**t.
All our governments are actively out to harm us!

You know how cold space is? About -454.765 F
It may be a sweltering 100 degrees in LA one day, but at that exact same position 32,000ft up it would still be from -20 to -40 deg.
The closer you get to space the colder it will get exponentially.
I don't have to.... it's obvious.... if you are fooled by a 1-2 page PDF made by NASA then you have no ability to distinguish lies from truth when told by the government.
If you are unwilling to accept that a large portion of people do not give credence to your sources on contrails ....ie... NASA and the Air Force then you should leave the conversation......because I will not stop saying that the science of persisting contrails does not add up. Period.
Nice find, I didn't realize that. I figured it just kept dropping. But still, any commercial flight is in the -deg range at cruising altitude.

Kind of - that's correct up to about the altitude aircraft fly, but at a certain altitude it actually stops cooling, then it starts to get warmer! Then higher up it starts getting cooler again, then warmer, eventually getting way warmer than on the ground, above the boiling point!
When you get into space, there's not actually a measurable temperature, as there is nothing to measure. In fact most of the temperatures in that graph don't really mean much, as there's practically no air there to hold the temperature, so it's not too different to being in a vacuum.
So maybe it is a bit of a hard concept after all
- Taken from: imagine.gsfc.nasa.gov...
If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there.
More than that, you will never accept any evidence that contradicts your position. That is willful ignorance. Be ashamed.
