There is a great deal of debate over the existence of chemtrails. Critics claim that the hazy lines in the skies over Denver are merely the remnants of contrails, or water vapors and crystals. Conspiracy theorists, as they are commonly referred to, believe that chemical trails, or chemtrails, left by high-altitude planes, are filled with harmful ingredients that pollute the air, water and soil, as well as cause major medical conditions.

To, hopefully, clear up the misconception between the harmless contrails one may see overhead, and the noxious chemtrails that crisscross the sky like a tic-tac-toe board on an almost daily basis, readers should give careful thought to the facts below.

What are contrails?

A contrail, short for condensation trail, is a trail of condensed water from an aircraft or rocket at high altitude, seen as a white streak against the sky. After a few minutes of appearing behind a jet, it will dissipate.

They form due to the water vapor from the engines of aircrafts. However, contrails can appear when air pressure changes over the entire surface of the plane’s wings. As with any other cloud, contrails are made purely of water that take the form of the suspension of billions of drops of liquid or ice crystals.

Temperature and humidity at certain altitudes determines how much vapor is left behind. Some contrails are only visible for a few seconds or may be seen for several hours. Most contrails, however, vanish rapidly behind an aircraft. It is quite rare to see these vapor clouds last more than a few minutes.

Contrails resemble natural cirrus, cirrocumulus and cirrostratus clouds. According to a paper written by Patrick Minnis for the Atmospheric Sciences, NASA Langley Research Center in Hampton, Virg., contrails are often referred to as cirrus aviaticus. Mr. Minnis states that, “Rising global air traffic and its associated contrails have the potential for affecting climate via radiative forcing. Current estimates of contrail climate effects are based on coverage by linear contrails that do not account for spreading and, therefore, represent the minimum impact.”

Contrails that linger for hours at a time and spread over miles in the sky, are more often than not, called chemtrails.

What are chemtrails?

There are strong proponents who claim that chemtrails are very different from contrails. It’s noted that a chemtrail is a trail of “cloud” that lasts for several hours and spreads as it’s emitted from the airplanes. The theory is that there are natural and unnatural chemicals and minerals being dispelled from high-flying jet engines. In 2007 KSLA news in Shreveport, Louisiana conducted an investigation in which they tested the substances that were emitted from one of these chemtrail planes and found high levels of Barium (about 6.8 parts per million) and Lead (about 8.2 parts per million), along with trace amounts of arsenic, chromium, cadmium, selenium and silver. This very well could have been an isolated area for testing, but the theorists believe these chemicals and minerals are spraying the sky for the purpose of releasing toxins into the skies above Denver and other cities across the U.S.

Other chemtrail theories suggest that the jets are conducting weather modifications to offset global warming. The government, however, has neither denied nor confirmed the existence of these so-called chemtrail planes.

So, if you look up at the sky and see a crisscross pattern of clouds, you have two options to guess from. Are they mere vapor trails from a plane flying at a high altitude or are they chemicals being sprayed for weather modification, or worse, depopulation?
