Frequency of contrail formation outpaced increase in airtraffic

Are we to believe that contrails are just a natural occurence?

I don't believe it, and have to question anyone that accepts
that statement.

Interestingly, notes Carleton, since the 1970s the frequency of contrail formation has outpaced the increase of air traffic in these areas. If this trend continues, he says, it could further decrease daily temperature ranges and even evaporation for those regions, a change that could be detrimental to certain trees, plants or insects sensitive to temperature and moisture changes.

Returning to the fact that only 10% to 20% of the country’s airspace is conducive to forming contrails at any given time,

The simulations show that even in areas
suitable for contrail formation, only a small fraction of all flights produce persistent
contrails that are detectable by satellite.

The next statement will show that if the conditions for a contrail to form exists, the aircraft should be worrying about de-icing.

if T > -40°C, RH > 100%
-need activated ice nucleus, pattern for the crystal
- aircraft icing: plane is a big nucleus

It is my regret to inform you that contrails are not normal occurences, and therefore what we are calling persistent contrails are actually CHEMTRAILS and your governments and meteorologist are telling us outright lies, to cover for some sort of sinister weather modification.

Believe it!
