Now I haven't been formally trained in weather science, but if you'd care to explain why people funded by this organisation would lie about how
meteorology works (because it forms a fairly large part of this book), please tell me.
Once upon a time, in WWII, there were massive aircraft maneuvers which included dog fights, flak, smoke etc. in winter skies over europe. Contrails,
true contrails, were in evidence and were unwanted because the enemy could easily spot your plane even at altitude. Since that time, in the 1940's,
over 60 years ago, technology has been developed to eliminate the contrail. Contrails, in those days, persisted for, perhaps, 15 minutes at the
Fast forward to 2012. Today, what is being called a contrail, persists for hours, eventually turning into fake cirrus (called cirrus aviaticus) and,
on a daily basis, causing a blue sky to become completely overcast. These are chemtrails. The deliberate manipulation of the atmosphere.
Further, this persistence takes place at altitudes and temperatures and particle saturation levels not previously conducive to contrail formation. It
takes place without weather fronts.
Forecasting haze, caused by aircraft, is not a weather forecast. In order to forecast haze, caused by aircraft, one needs to know about the dispatch
of chemtrailing craft: how many, where, when.
Excellent post, very straight forward and readable to anyone here.
Star for that.
And yet entirely false. Particularly "Contrails, in those days, persisted for, perhaps, 15 minutes at the outside."
Contrails are ice clouds formed by a momentary increase in humidity. They last as long as other ice clouds do - up to several hours. That's just
physics, and it has always been thus. See this 1970 article for example:
Airborne Observations of Contrail Effects on the Thermal Radiation
The spreading of jet contrails into extensive cirrus sheets is a familiar sight. Often, when persistent contrails exist from 25,000 to 40,000 ft,
several long contrails increase in number and gradually merge into an almost solid interlaced sheet.
Contrail development and spreading begins in the morning hours with the start of heavy jet traffic and may extend from horizon to horizon as the air
traffic peaks. Fig. 1 is a typical example of midmorning contrails that occured on 17 December 1969 northwest of Boulder. By midafternoon, sky
conditions had developed into those shown in Fig. 2 an almost solid contrail sheet reported to average 500 m in depth.
