Claims by sources that include the EPA, NOAA, FAA and NASA that contrails, or water vapor trails, may persist for extended periods under conditions of higher relative humidity are taken to task in this Carnicom work. Working from a foundation Carnicom calls the “Relative Humidity Thought Experiment”, Carnicom develops the reality that the rate of evaporation of the contrails is inversely proportional to the humidity in the atmosphere. Carnicom develops a mathematical model to test this idea, and shows that even at high levels of relative humidity, the effect on the evaporation times is generally insignificant and minor. The truth now includes overwhelming evidence that the populace has been systematically subjected to a covert, extensive and sustained project of aircraft aerosol dissemination without their consent.
The United States National Climatic Data Center, National Oceanic and Atmospheric Administration, changed their visibility reporting methods, as well as data results, from a maximum 40 miles to a limit of 10 miles. It is of question why this change was made, and whether it is related to the increasing numbers of aerosol observations. Graphs are shown for the period January 1994 to March 2001 for Santa Fe, New Mexico, showing not only the changes to the reporting standards, but also if is seen that the number of days of visibility under 10 miles is substantially increased.
