How Clouds Form
Molecules of water vapor will bounce around like molecules of other gases unless you give them a reason to stick together. Cooling the vapor slows the molecules down, so they have less kinetic energy and more time to interact with each other. How do you cool the vapor? When you squeeze the bottle, you compress the gas and increase its temperature. Releasing the container lets the gas expand, which causes its temperature to go down. Real clouds form as warm air rises. As air gets higher, its pressure is reduced. The air expands, which causes it to cool. As it cools below the dew point, water vapor forms the droplets we see as clouds. Smoke acts the same in the atmosphere as it does in the bottle. Other nucleation particles include dust, pollution, dirt, and even bacteria.
Several scientific studies have suggested that aviation may contribute to detrimental chemical changes in the atmosphere (particularly ozone content), as well as possible climate modification.
With in the next 10 years it will become very clear how real chemtrails are

Yes, contrails are manmade clouds. But the "History" channel got it wrong, or you did and it isn't a new episode. It aired in March of last year.
I believe what they were talking about was a study of temperatures in the the three days following 911. What that study found was that with no contrails, both nighttime and daytime temperatures increased. The opposite of what you have said.

Contrails disappear, Chemtrails do not.

There are no such things as "chemtrails". NO airplanes that "spray" them at over 30,000 feet. NO equipment for "spraying, NO tanks to contain a "chemical", and NO facilities on the ground for loading and delivery of the alleged "chemicals".
