if you are right it is not what it looks like.
That is correct. It LOOKS LIKE planes are "spraying" something, but it's not that at all. It's water vapor from combustion of the fuel they use. This is much like it sorta LOOKS LIKE the sun orbits the Earth every day, but that isn't what is really happening.
I have asked you twice, now, by what mechanism you think the trails planes make can cause storms. You have no answer? How can you claim it's happening if you can't explain HOW?
