[Admin: tread split off and retitled from https://www.metabunk.org/showthread.php?p=25705#post25705 ] I think others feel she is the Chemtrail poster girl for whatever reason . . . they tell me she is endorsing several videos about chemtrails on her FaceBook, etc. so seems the discussion is relatively moot. My primary point was . . . she now has been given alternative info contradicting the info from the CT Advocates . . . give her time to assimilate the information and see if she changes her spots. I don't know you training or education but mine is not geophysical science; I have been researching contrails for over two years and find it confusing, obscure, and difficult to pin down precise explanations detailing the interactions and dynamics of contrail formation, persistence and cirrus cloud formation and propagation and the precise way it effects micro and macro climates . . . the early research regarding the simple Appleman Chart is no longer adequate with the new engine efficiencies and effects of increased air traffic . . . effects of global warming, etc.
