We obviously will not agree and the evidence is there that you will not or cannot hear, fine.
I have consistently asked for scientific results, that's all. I won't say you're stupid, I won't say they don't exist. I need irrefutable
evidence and so far the "evidence" presented is not irrefutable.
Certainly your grandmother noticed changes in contrails because much has changed. Flight paths, flight traffic, flight altitude, engine technology,
fuel technology, accumulation of atmosperic contaminants, overall air temperatures, amongst other things have all changed
. It should be of no
surprise that contrail behavior will exhibit changes as well. Change alone is not evidence of anything conspiratorial.
