If it is geoengineering, you shouldn't be referring to contrails in your complaints. I've been observing persistent and non-persistent contrails for the past 70 years and that is all we have. (Plus, I am an aeronautical engineer and it is my business to know about them.)

I will make you a prediction: for any state that outlaws "geoengineering," there will be no cessation of contrails, and no indictments for geoengineering. But I will drop the argument. Do not be too surprised if the subject fails to gain ground.

I am not in favor of geoengineering, by the way. It is ill-advised and futile. For any such enterprise to have a significant effect, it would need a massive program. Nature is big. Human impact is small. I hope we can agree that cloud-seeding for rain stimulation is benign (it leaves no trails and sometimes we need the rain).

Just as a friendly aside, have you had an opportunity to view the meteor crater near Barringer? It is truly a spectacle. One feels like an ant on the rim of a teacup.
