I didn't know every cloud produced rain.
Do they need to make it rain, or just block out the sun or perhaps, do both??? hmmmmmmm.....
Ok then, from now on, we'll call them "contrails mixed with chemicals". lol And, in case you didn't know, salt is a chemical compound; and so is water.
You need to put down the raid can. lol

That's not entirely true. There's plenty of documented evidence in favor of, than against. Contrails don't extend for miles and miles. That's ridiculous. And, let's clear up the misconceptions about "cloud seeding". Clouds are not required. Not sure why certain people insist, clouds are needed. The same CHEMICALS found in clouds, can be found in our atmosphere, at all times, so why the heck do they need a cloud?
There's not much of a debate because the other side is too busy saying, "that's not true".
In order to get the search results you're seeking answers to, you must first get the words right.Try this ---> Cloud Seeding; not "clouseeding". Let me know how it goes.
Do you actually understand how clouseeding works?
Will you stop the silliness, if i do?
Please show us how cloudseeding can make clouds out of thin air?
You would have known that, if you actually READ any of the information i've already posted; that you're so quick to chime in; ALL THE TIME. Are you done playing games now???
The concept of cloud condensation nuclei has led to the idea of cloud seeding, that tries to encourage rainfall by seeding the air with condensation nuclei. It has further been suggested that creating such nuclei could be used for marine cloud brightening, a geoengineering technique.

CON-trail comments made by CON-artists.
And in trying to have normal ADULT conversations about this topic tends to go in this direction.
It's sad, but when no proof exists, I guess the mentality must be dropped to this level.
In above freezing temperatures the air would have to be supersaturated to around 400% before the droplets could form.

Clouds are not required.
When was the last time you saw it rain without clouds?
You do understand what the word cloud stands for in cloudseeding don't you?
in case you didn't know, salt is a chemical compound; and so is water.
People need to understand, this stuff is happening on a molecular level; which is smaller than this dot ---> .

You can't win a debate based on facts; and you KNOW IT!
The trails that aircraft leave in the sky are called “contrails”, which is short for “condensation trails”. They are formed by the condensation of the water vapor in the aircraft exhaust.
When you breath out on a cold day, you see a little cloud of condensation form from your breath. This is the same kind of thing, your damp warm lungs add moisture to the air, and when you breath out, you get condensation.
But the condensation from your breath quickly evaporates, usually in less than a second. Condensation trails from a jet can last for many minutes, even for hours sometimes. So why is there this difference? Why do jet contrails sometime persist, but your breath condensation quickly evaporates?
The difference is because a contrail freezes.
It’s really that simple. Contrails form at -40 degrees Fahrenheit (which is also -40 Celsius), or colder. At that temperature the tiny drops of condensed water will instantly freeze. Once frozen they can not evaporate. They also can’t melt, as it’s -40. They can however fade away through a process known as “sublimation” – where a solid turns into a gas.
You’ve seen sublimation before. Dry Ice is frozen carbon dioxide. It does not melt, it just sublimes directly into the gas. If you take a bit of dry ice, and just leave it in the sun, it will just kind of fade away. That’s what happens to the ice in a contrail.
Ice will only sublime if the humidity (at that altitude) is lower than around 60% to 70%. So if it’s a bit higher then the contrail can last for a long time, just like clouds do sometimes. If the humidity is low, then the sublimation happens very fast, and the contrail only lasts a minute or so. If the humidity is high (above 70%) then you get reverse sublimation (also called desublimation or deposition, where water vapor turns directly to ice, but only when in contact with ice), and even more ice will form on the frozen condensation, the ice crystals will get bigger, and sink faster, causing the trail to spread out as it sinks through altitudes with different wind speeds.
Apparently, they're not. I found the answer, you still can't find. lol Keep searching tho'. Eventually, you'll get it. lmfao
It doesn't matter how you spell it the results are the same.

"Cloud seeding exists, it's just not geo-engineering." Yaaaaawn.
WonderBoi
Note to add: BTW...when i breathe, in the cold air, it freezes; and the cloud lingers in the air, all day. lol

An engineer from Charlotte,
I doubt he is a engineer, as a engineer would know that all he videotaped were normal contrails....

Admit it, the word "chemical" confuses you. lol
