One proposed solution to the problem of global warming involves the seeding of the atmosphere with metallic particles. One technique proposed to seed the metallic particles was to add the tiny particles to the fuel of jet airliners, so that the particles would be emitted from the jet engine exhaust while the airliner was at its cruising altitude. While this method would increase the reflection of visible light incident from space, the metallic particles would trap the long wavelength blackbody radiation released from the earth. This could result in net increase in global warming.

Such materials can include the class of materials known as Welsbach materials. The oxides of metal, e.g., aluminum oxide, are also suitable for the purpose.

Well that certainly sounds familiar... I had year-round cold symptoms when I lived in Arkansas, and we had plenty of that yellow stuff on everything. I just assumed it was pollen from the trees. I wasn't the only one who was effected by it either. Sometimes I'd be up all night coughing so hard that I'd cough blood. I'm glad I don't live there anymore.

A question to others, I see three planes leaving trails, but in front and between the two front ones, there is also another shape flying in the same direction at the same speed. What is it? Is it another plane at higher altitude, is it a flying disk (I don't call them UFO's as they are mainly no longer Unidentified) or something else? My vision is not 20/20, and I don't have great software to zoom into infinity etc. so other peoples findings will be greatly appreciated.

Chemtrails are controversial. Investigators have collected samples of chemtrails for analysis, which U.S. government agencies such as the EPA have refused to test. James told us that a member of U.S. Congress recently tried opening an investigation of them, and was advised by a high-ranking military official that if she valued her career and her family’s health, she should cease her investigation (which she did). If chemtrails are a genuine covert action phenomenon, I doubt the motivation behind chemtrails is benevolent. The military and related attention to the Mount Adams area likely has nothing to do with the “threat” that UFOs pose to humanity, but the “threat” that they pose to the world’s power structure. All the attacks and other games are most likely not to keep humans safe from ETs, but to keep ETs from openly interacting with humans, in alignment with the Brookings Institute’s advice to NASA many years ago. James has endured great harassment from the people trying to remove UFOs from public awareness.

Quite simply the whole chemtrail paranoia thing comes - in my opinion - from bad science, people refusing to understand the physics of it all and making assumptions about things they clearly have no, or very little knowledge about. They look up and see lines in the sky and automatically assume the sky is falling on their head and it isn't.

Yes. However, for this to be effective it would need to be done on a massive scale, there would be no reason for secrecy, and it would have be be carried out at an altitude at which persistent contrails will not form, otherwise it's counter-productive - persistent contrails add to global warming.
So, we'd know all about it and we wouldn't see any visible signs of it being done.

Meanwhile, it never ceases to amaze me how many people believe in chemtrails without having any knowledge of persistent contrails nor the efforts being carried out around the world to better understand their impact on climate and ways of reducing them. But maybe there's a reason for that? Maybe the info in the following links is what the chemtrail believers don't want you to know:-
www.epa.gov...
www.grida.no...
www.ozone-sec.ch.cam.ac.uk...
www-pm.larc.nasa.gov...
After all, if you knew the truth, you just might start thinking the chemtrail believers were a bit silly
(Note: I do not exclude the possiblity that some limited scale chmeical spraying of populated areas may have been carried out in the past by the military, and may even still be carried out. However, such spraying would be at low level - it would not result in the formation of high level cirrus clouds as chemtrailers claim )

Are you seriously arguing with a patent that spells it out for you?
And can you please source your information
Also, how do you explain planes flying in the same vacinity where one plane has a normal contrail and another plane has a chemtrail????
Take, oh I don't, THE FIRST VIDEO IN THIS THREAD!?!?!?!
Thanks for the links, but each one that mentions "persistant contrails" also mentions that it takes metal particles to form these
which is consistent with the patent I quoted.
Also, I am certain that they are studying these "persistant contrails" as it pertains to global warming which only makes sense and is again consistant with the patent I quoted.
I think you are a bit silly, and I don't appreciate you calling me silly since you are the one who has not done their research.
Nice little disclaimer after you just got done insulting my intelligence.

The Aerosol Crimes video points out some interesting facts regarding how natural contrails do not last hours on end in the sky...
Contrails generally last one to two hours, but can last as long as six
"We know from satellite imagery that clusters of contrails can last for two days. If carried by the upper jet stream through the troposphere, they can travel hundreds of kilometres."
'Worse is when the contrails last for hours.'
The main products of hydrocarbon fuel combustion are carbon dioxide and water vapor. At high altitudes this water vapor emerges into a cold environment, and the local increase in water vapor can push the water content of the air past saturation point. The vapor then condenses into tiny water droplets and/or desublimates into ice. These millions of tiny water droplets and/or ice crystals form the contrails. The energy drop (and therefore, time and distance) the vapor needs to condense accounts for the contrail forming some way behind the aircraft's engines. The majority of the cloud content comes from water trapped in the surrounding air.[citation needed] At high altitudes, supercooled water vapor requires a trigger to encourage desublimation. The exhaust particles in the aircraft's exhaust act as this trigger, causing the trapped vapor to rapidly turn to ice crystals. Exhaust contrails usually occur at above 26,000 feet. where the temperature is below -40°C (-40°F).[1]

First i want to highlight the obvious difference between a contrail and a chemtrail - notice how the contrail dissapates very quickly and then notice how the chemtrail expands and lingers.
