Jets in the federal climate change puffed their way over Hamilton County on Saturday to lay down their talcum powder-like material that spread across the sky in wispy clouds.
From Hixson at 10:30, dozens of jets were either visible or had just cut off their plume-making. I was delivering a son to another dad for a caving expedition at Books a Million along Highway 153, and saw from that parking lot, and from the Lowe’s parking lot 30 minutes later remarkable evidence of the nature of the program.
The aerial activity is, indeed, a deliberate policy.
The plumes that tattoo the sky and dissipate into clouds are not mere water condensation — or contrails, which are created by superhot jet engines drinking in subzero-degree damp air at 40,000 feet. Water vapor trails are contrails, and generally dissipate rapidly.
I saw both kinds of trails this morning. I even saw one jet, seemingly at equal height to others, making no trail at all. Humidity is not the cause of the trailwork.
As many as 30 plumes were visible at any one time this morning.

The federal program of weather modification diffuses coal fly ash, according to J. Raymond Herndon, who has advanced the weak combat against stratospheric aerosol geoengineering with an important paper. In that paper, which immediately caught academic flak and was retracted, he says his studies of jet leavings over San Diego point the finger…
