Please see below website for information on humidity at different altitudes and the quote below the link from that website. FYI I searched for humidity levels at different altitudes and just picked this link as it looked valid and matched others.

I read through about half of this thread but realized the same argument was basically being repeated again and .......FYI I searched for humidity levels at different altitudes and just picked this link as it looked valid and matched others.

"Lowering the air temperature increases its relative humidity for the same partial pressure of water vapor. In general, the relative humidity of a parcel of air will increase as the air rises, because the temperature effect outweighs the vapor pressure effect."
Assuming that is true the video provided should not be possible, water vapor or humidity should be higher the higher altitude and that is the trail that should be hanging around. What we see is the opposite, the only conclusion I can see is something besides water vapor is causing the lower contrail or "chemtrail" to hang around.
That does not mean, however, that if a parcel of air at 80% humidity at sea level were lifted to 5,000 feet its relative humidity would remain at 80%. First of all, its total pressure would drop, so the partial pressure of water vapor would be less than at sea level for exactly the same mixture of air and water! Additionally, the temperature would drop as well, because the air parcel will expand, and the energy of expanding comes at the expense of thermal energy. (Another way to think of this is that the potential energy of the air increases when it rises, so conservation of energy requires that its kinetic - that is, thermal - energy decreases by the same amount.) Lowering the air temperature increases its relative humidity for the same partial pressure of water vapor. In general, the relative humidity of a parcel of air will increase as the air rises, because the temperature effect outweighs the vapor pressure effect.
It still takes a little bit of a leap to come to the conclusion Korg provided but not without reason. It would be nice if someone could confirm if those quoted documents from snowden are valid.

Contrails do indeed exist... They dissipate and do not form cloud cover...
Why do you believe this to be correct information?
Only under certain conditions do Contrails expand into cloud cover... Please read further into the thread where this has been discussed.

The arrogance and certainty of the OP's responses to criticism is a small annoyance in this thread. I seem to be siding with the critics here despite being indecisive over the whole chemtrail conspiracy. OP's sources are weak and seems to often base claims mainly on his own and others observations.
Again, I'd like to reiterate I am neutral, albeit somewhat interested, regarding the chemtrail conspiracy. Certainly plausible in theory and I wouldn't put it past our ailing government to resort to such evils... but again, this sort of thing requires WAY more credible evidence to even gain traction to becoming fact. Too much speculation & observation without representation imo.edit on 2-10-2013 by SNX928 because: Rephrasing of a sentence.

So first they don't, then they do, sometimes?
If you accept that they can and do expand into cloud cover (under conditions of suitably high RHI) then how can you tell when, or even if, you are looking at a chemtrail?
That appears to be self defeating at the most basic level.

There's no ergo about it, simply rewording the statement of acknowledgement I included in the question, as a point of clarity, does not constitute an answer.
How do you know the conditions 7 miles up are not conducive to persistent contrails and lead you to conclude you are looking at a chemtrail?

If you want to believe that all contrails are natural

That's what our transatlantic cousins call an epic fail.
Seriously chap, believe what the hell you want, but don't go around pretending you are more enlightened than everyone else and if you cannot answer a question, just admit it.
Chemtrails expand into clouds under all conditions and can be seen all over the place....

Why would chemtrails expand into clouds under ALL conditions?
Do chemtrails not require moisture to expand as contrails do?
