Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 3.5°F (1.94°C) per 1,000 feet (304 m) of altitude.
I have a feeling that 11thHour is a pilot, Don. You bantering with me is all fun and games, but I think you're going to find that you're way out of your league if you choose to take him on.
Seems you demand others answer your questions when in over 700 posts you have refused to answer theirs.
And you expect people to respect you?
I already said I will answer anyone's questions except for you and swagger because if you read back in these posts anyone can see you two have been disingenuous.
Contrails are all made of the same materials and are formed in the same way, but exist for different lengths of time. Because of the differences in contrail "life-spans", contrails can be divided into three groups: short-lived, persistent (non-spreading), and persistent spreading. See the Contrail Formation Guide for more information on how contrails form.
Short-lived contrails look like short white lines following along behind the plane, disappearing almost as fast as the airplane goes across the sky, perhaps lasting only a few minutes or less. The air that the airplane is passing through is somewhat moist, and there is only a small amount of water vapor available to form a contrail. The ice particles that do form quickly return again to a vapor state.
Persistent (non-spreading) contrails look like long white lines that remain visible after the airplane has disappeared. This shows that the air where the airplane is flying is quite humid, and there is a large amount of water vapor available to form a contrail. Persistent contrails can be further divided into two classes: those that spread and those that don't. Persistent contrails look like long, narrow white pencil-lines across the sky.
Persistent spreading contrails look like long, broad, fuzzy white lines. This is the type most likely to affect climate because they cover a larger area and last longer than short-lived or persistent contrails.
Contrail cousins are things that look like contrails but actually arise from a different physical process. For example, under the right conditions you will see vapor trails form from the wingtips of a jet on takeoff or landing. This phenomenon results from a decrease in pressure and temperature in the wingtip vortex. If conditions are right, liquid water drops form inside the vortex and make it visible. These evaporate very quickly after they form.
Contrails can be found over most of the planet. Now that jet plane traffic, both civilian and military, can be at anyplace over the globe at anytime, contrails are becoming more and more common. This picture was taken by the NOAA-12 satellite as it passed over portions of Europe in 1995. It is very obvious from this color enhanced satellite image that the atmosphere was very conducive to the development of contrails on this date (5 April 1995) and that these contrails were long-lived enough to accumulate with many criss-cross patterns over the same heavily travelled portion of air space.
Contrails have been recorded throughout the history of jet plane travel. Many reports exist from World War II of situations where the accumulations of contrails was so extensive that pilots were unable to keep visual contact with neighbor or enemy planes during combat. Contrails have been recorded from the Sahara Desert to the South Pole indicating that contrails are not constrained to only populated regions of the Earth.

No, not really. I never said what my profession is.
So your not going to give me a temperature you feel comfortable with?

Disingenuous?
I asked you in post #747 to point out to me a contrail over a thousand miles long... Did you answer? NO
Why? because you couldn't, there were no contrails over a thousand miles long.
The last photo over Europe? chemtrails? <errr> wrong again....
So in your mind if you call someone disingenuous that means you can sprout any BS you want and not be called out...
Gotta admit, in over 700 posts your spots have not changed, BS through and through..

Disingenuous means you are not interested in the effort here to discuss and collaborate in the subject matter. We have answered your questions but you don't consider or honestly argue the content, you just throw it aside and continue your quest to sidetrack true discussion. You just want us to stop discussing the subject and you try anything you can to accomplish that goal. This is typical Troll actions.
As far as getting traction on the subject and the truth I think we are progressing well despite you and swagger's attempts to derail the thread. I think we have presented some very good evidence and theories. I'm more convinced now that geo-engineering is real, the alleged contrails are chemtrails ... and the world governments are operating this secret covert program.
