I have family members hell bent on the Chemtrail conspiracy and aircraft spraying stuff on us.
I’m trying to explain it’s to do with altitude, moisture and temperature.
But I need a bit of help. We’re from Brisbane, Australia and we’re visiting Porto, Portugal. Porto has much longer and larger spread contrails than we have in Brisbane.
So my argument of “You get longer and wider contrails due to more moisture in the air” is failing on me. Brisbane (at sea level) has a lot more humidity than Porto.
So why are the contrails much longer and fatter and longer lasting in a less humid area like Porto - than Brisbane?
I’m guessing maybe the humidity is felt more in Brisbane as the moisture higher up - is lower? And up there - the humidity is somehow less?0
