Oh cool, so we can agree the air composition has changed... then, at this point i shall add this component..

"Barium is used not for modifying the weather, but rather as a tracer for gathering atmospheric data. Barium performs in this capacity because barium can be radioactive. It shows up on radar well. The literature pertaining to weather modification and the atmospheric sciences is full of references to radioactive materials such as barium being used as atmospheric tracers"...

Just cut and paste job with another material showing up in test results.. So here they adit there they they are adding another substance for another cause... so, you see, its not only chem-trails for weather, it serves many purposes.. With what I and many others are noticing about our skies changing so rapidly, more storms, FREAK weather problems.. its tied in to this subject matter.. I have stated that this isn't a conspiracy page/blog .. i have followed the white rabbit long enough, and the more distracted i get, i find this phenomenon winds up right at the heart... please do have a look into the subject.. finding out first hand knowledge kicks second hand to the back.. be your own truth seeker my friend. Please do feel free to message with any findings, as we are all here to learn at the end of the day..
