however, the behaviour of chemtrails differ  there is no such thing as chemtrails. its literally as simple as that.  It also makes me wonder why there is just ONE published paper amons 77 atmospheric scientists where one claims the ground contained as much barium as the sky.   Because papers are submitted for peer review before being published. when the chemtrail clowns have anything mildly scientific to talk about it might get looked at. Just because none have ever been published doesnt mean thousands of retarded cunts havent tried to submit it.
