Yes, thanks for the news, but I want to clarify one thing, how doe the contrails which are reflecting enough sunlight into space contribute to global warming it be global cooling, please clarify.
Because silver iodide (silver salt) kills the trees, plants, everything eventually.
Take a look at the salt flats for example. The less greenery, the hotter it gets.
Also, the use of liquid carbon dioxide creates a haze that has a blanketing effect.
Combine that with the higher pollution from the extra air traffic, and you can probably figure it out, since your avatar has that fancy satellite (space station) in it.

I saw the on wiki and even it clearly states that only from below it exerts warming effect by trapping the gases.
Feedback effects due to clouds are an area of ongoing research. Seen from below, clouds emit infrared radiation back to the surface, and so exert a warming effect; seen from above, clouds reflect sunlight and emit infrared radiation to space, and so exert a cooling effect. Whether the net effect is warming or cooling depends on details such as the type and altitude of the cloud.
So, you see the reflecting sunlight does not cause global warming it causes cooling that is what I mentioned.

"seen from above..."
we are on the ground(well most of us)
"seen from below...and so exert a warming effect"
straight form your post.
You are confused contrails of aeroplanes dont contain silver iodide which is used in cloud seeding, the contrails contain only the mixture of gases like co2 and cfcs, and they only cause global warming.
This invention relates to the modification of supercooled clouds. The principle of the current large-scale weather modification method, including the technique of rain augmentation seeding, involves artificial generation of ice crystals in supercooled clouds and fogs with a resultant spontaneous phase change.
...
The former works when a portion of the cloud is chilled below -40° C. by a strong coolant.
...
The second category of ice nucleants is called ice (forming) nuclei, and ice forms on the individual particle of the nucleus substance. Silver iodide (AgI) and metaldehyde are examples of artificial ice nucleus substances. AgI, the most widely used nucleus substance for weather modification, is expensive and toxic to small or baby fish, algae and bacteria.
...
Preferred embodiments of the invention are illustrated in the accompanying drawings in which:
FIG. 1 illustrates the flow of air and ice crystals with a cloud seeded according to the invention;
FIG. 2, a liquid carbon dioxide tank and rack arrangement for use in a cloud-seeding aircraft; and
FIG. 3, a diagrammatic depiction of a series of liquid carbon dioxide cylinders showing the arrangement of spray nozzles; and
FIG. 4, plumbing of liquid carbon dioxide spraying system on a seeding aircraft.
...
FIG. 2 shows a design for the LC rack in aircraft use. It satisfies the requirement of being housed in a seeding aircraft and has been approved by the FAA (Federal Aviation Administration).
...
To operate the seeding system, after confirming the existence of a seedable condition in the cloud, all the manual valves of the LC cylinders are kept open from the beginning, and a cylinder solenoid valve will be opened and kept open until the cylinder is empty. The empty condition may be determined by the warming of the seeding nozzle detected by the attached temperature sensor. When the first cylinder has been emptied, the cylinder solenoid valve will be closed and the second cylinder solenoid valve opened for continuing operation. This method will be applied until all the cylinders will have been emptied. In this manner, partially emptying the cylinders can be avoided, making their replacement more efficient.
And since when did aeroplane engines use silver iodide
Silver is relatively expensive how can such huge quantities be bought by the airline company as fuel, the airiline will become bankrupt within a week which is worse than getting bankrupt due to the high fuel costs.
Two experimental cloud seeding experiments over Beulah were conducted by the U.S. Weather
Bureau, National Hurricane Research Laboratory, during Project Stormfury on 23-24 August 1963.
Approximately 800 lbs of silver iodide smoke were dispersed into the clouds surrounding the eye
during these two days.

Scientists will tell you that those long trails left behind aircraft are just water vapor, and you should just go back to watching TV, instead of questioning the "experts"
Contrails form high in the atmosphere when the mixture of water vapor in the aircraft exhaust and the air condenses and freezes.
