I dont need to explain myself to you or anyone for that matter.
Ive been here long enough and as far as Im concerned your opinion of me is redundant.
But, feel free to keep embarrassing yourself....
...as to your comment about "they want to make as much cloud cover as possible"?
Do your own studies, and research....and IF you can find some sort of PROOF of your claims of substantially increased cloud cover in recent years, like the last 10-15 (as you so vehemently claim) then by all means, SHOW EVERYONE!!!
But, since your claims are full of hot air, I doubt any of us will be seeing any such "evidence" any time soon....

Random quotes from Wiki with no context are supposed to prove a point?
Well, since you didn't, I'll comment on it. The trouble is, such injections have not been found to be economically, environmentally and technologically viable. Because very little research has been done on the economic, environmental, or technological aspects.
Here's a direct quote from the CFR article aluded to on wiki (I find it useful to go to the source rather than picking out a few choice phrases).
Despite years of speculation and vague talk, peer-reviewed research on geoengineering is remarkably scarce. Nearly the entire community of geoengineering scientists could fit comfortably in a single university seminar room, and the entire scientific literature on the subject could be read during the course of a transatlantic flight. Geoengineering continues to be considered a fringe topic.
Here's the article.
iis-db.stanford.edu...
Please make sure that the quote above is in context with the thrust of the article; that any geoengineering scheme would have to involve extreme caution, openness, and cooperation. And by all means, please look for anything that indicates that any geoengineering activities are already being undertaken.

The burning of hydrocarbons from aircraft and vehicles, emits both dust and water vapour.
The basis behind contrail development is that the water product from aircraft fuels, undergoes a prcoess called sublimation, where water vapour skips the transition to its liquid phase, and is immediately turned into ice. This occurs due to the super cold environment up there.
If the temperature is cold enough, contrails can persist, regardless of humidity. The same can be said for natural cirrus clouds. Its rare for us to get high levels of humidity up there, even if they are present

Good idea. Let's keep the corn belt cooler than everywhere else.
What happens when you do that I wonder. Well cooler air is more dense than warmer air so you get a high pressure area. What happens in a high pressure area? Low level clouds don't form so more sunlight hits the ground so it gets hotter during the day and cool at night. Low level clouds don't form so it doesn't rain. It sounds like you want to turn the corn belt into a desert. Why do you want to do that?
The problem with geoengineering is it's an all or nothing thing, rife with unexpected and unknown consequences.
U.S.
crops currently have a market value slightly less than $100 B/year, and direct and indirect (due to UV-B and –C and
to ozone, respectively) photodamage may be very conservatively estimated to be several percent (corresponding to
a mean ground-level ozone concentration of 50-70 ppb), for a U.S.-only cost of several times $1B/year; world-wide
costs are likely to be at least 12 times larger,or several times $12 B/year, as the U.S. accounts for less than 8% of
global production of primary crops. Skin and crop photodamage thus likely amounts a substantial multiple of $20 B
annually, most of which could be avoided by scattering back into space from the stratosphere the majority of the
incoming solar UV-B and -C irradiation, as well as the ‘hard’ or blue ‘tail’ of the UV-A spectrum
In a few decades, the option of geoengineering could look less ugly for some countries than unchecked changes in the climate. Nor is it impossible that later in the century the planet will experience a climatic disaster that puts ecosystems and human prosperity at risk. It is time to take geoengineering out of the closet -- to better control the risk of unilateral action and also to know the costs and consequences of its use so that the nations of the world can collectively decide whether to raise the shield if they think the planet needs it.
