Have you watched the skies the past couple of years?
Aerosoling has been going on big time
Criss cross applesauce plumes of fuzz that linger for hours and spread into a white haze over our former blue sky
Sometimes they even get creative and do spiral plumes
“ contrails’ my patoot
Even plumes being laid in parallel tracks at night
I was wondering how they were going to get Trump to keep paying for this
I think we’ve seen the gambit

Haven't listened to Art Bell in a long time, but I remember one of the shows on this "topic".

Basically, it boiled down to who owned the patent on it (TRW, iirc), and oh, btw, why not simply require it as an additive to jet fuel, and let the airlines do all the work?

That is, if you believe this stuff.

I tend to go with that Mother Nature is more responsible than specifically humans, but YMMV.

Contrails have been around ever since we had jets.

The number of jets have been increasing for decades.
