Despite the fact that the video you "found" has been posted elsewhere on ATS already (cannot recall exactly where, perhaps someone else remembers?),
did you actually listen to what John Chancellor said, or just jump at the title added to the video by the person who posted it to YouTube?
At merely the first :20 seconds or so, Mr. Chancellor mentions the *theory* that the contrails might "...be changing our weather for the
So, why the "fuss" and "dire predictions" in the Opening Post?
Oh, and be sure to jump to at least point 1:00, and listen very, very carefully there, too.
Finally, of course, this video (from 1980, recall) completely destroys the silly "chemtrail" meme, doesn't it??
Paraphrasing a quote: "Contrails are water vapor...." Technically not accurate.....when one wishes o be too pedantic RE: their definition. But,
water vapor is the genesis
of a contrail.....and the primary original component. The water vapor has frozen into water ice crystals, of
varying sizes, and this is what becomes visible (since *everyone* already knows that water vapor is an invisible gas, correct?).
By the way, *others* will attempt to 'argue' that the turbine engine exhaust contains other components besides water vapor....which is true. BUT,
this fact is the situation at ALL times when the turbine engine is running, and burning its fuel! In fact, the turbine engine pollutes the most when
on the ground, and during takeoff and early climb, at lower altitudes....and when arriving to land.
The modern engine is most efficient, and cleaner burning, when at high power settings, at high altitudes, in normal cruise flight regimes....which,
ironically, it the only place that contrails will form!!!
