This video has a bit more substance to it, but makes the claim the earths weather patterns have been destroyed and all weather is man-made. I have no proof to absolutely say this is completely false. Yet these videos claim this is all fact but don't show any facts on how any of there theories could actually be mathematically possible.
Lets at least build some legs for this theory to stand on before such drastic claims are made. These 2 videos seem more like CNN videos that try and take the worst ideas someone could come up with to scare people for ratings.

Start with some theoretical math showing how much vapor some of these power plants and WSAC can produce along with the amount of energy needed. Here is a starting point. http://www.ctcombustion.com/oxc/sources/06-WaterVaporImpactsFinal2.pdf

Next show some studies for the claim that Doppler radar/Nexrad can steer clouds.
Lets at least quantify some of these ideas. Then you we begin to see if this theory even holds any merit.

I think the bold claims don't have merit at this point. I think there is much more merit in that humans contribute to a small amount of added water to the total rain fall. This is a very complicated subject by itself to prove let alone for these videos to claim humans control the entire earths weather.
