I used to believe this too and thought it was a crackpot idea. Until now, they’re openly saying they cloud seed and it’s no longer a conspiracy theory. It was the specific reason for the rain and flooding in Dubai.

Cloud seeding isn't new and it isn't a secret. It also isn't happening all over the place. It's an experimental process for increasing rainfall in areas where drought is negatively impacting crop harvests. It also doesn't generate the contrails that chemtrail conspiracy theorists insist are really the government spraying chemicals into the population. You're conflating two completely things.
You do realize there are many examples of the government directly spraying the populace, right?

I can list many others. It’s not a stretch of the imagination to suggest further malice, such as chemtrails.
Just stop. You're doing what every conspiracy theorist does. You're starting with your preferred reality, and fishing for nuggets of unrelated truth to disingenuously support the conspiracy theory. The fact that the government did something that partially reflects aspects of your conspiracy theory back in the 50s does not mean there is a mass government program involving thousands of planes on a daily basis going back decades to unendingly spray the population with "chemicals".
Also, the flooding in Dubai was largely the result of atmospheric warming following the general trend of warming. While cloud seeding was employed in Dubai, its effect on water retention in the clouds would have very minor, and not able to cause a flood. This is another case of people who don't understand what they're talking about taking a story containing a nugget of truth, and exaggerating its impact while conflating it with a conspiracy theory they're looking to prove. Chemtrails aren't real, and cloud seeding doesn't have anything to do with it.
