Geoengineering proof? Scientists link jet trails to changes in local weather patterns

by L.J. Devon, Staff Writer

(NaturalNews) It's not a conspiracy theory that the weather is being manipulated through the use of artificial clouds in the skies above. It's more of a scientific fact now than ever before. Humans can change the weather and the temperature of a region using everyday jet exhaust persistently and at the right atmospheric conditions. When the conditions are right, the jet exhaust can form into cloud-like contrails. According to a team of Penn State geographers, these jet contrails can form into ice cloud trails that mimic normal clouds, reducing Earth's surface temperature.

And now an influx of jet contrails in any region has been linked to reduction in temperature and changes in local weather patterns.

These small changes may explain the apparent rise in climate changes taking place on the earth, from region to region. On a grand scale, if contrails are lowering the surface temperature artificially over time, could this throw the balance of entire ecosystems off? Could this affect how atmospheric gases respond to changes? Could it change how the atmosphere regulates carbon dioxide and oxygen?

Contrails can form elevated ice cloud trails that influence temperatures on the ground

A jet's exhaust doesn't always form into full blown contrails that affect weather and temperature. A contrail forms under certain conditions, and when these conditions are met, contrails basically have the power to artificially cool local regions, potentially causing bizarre weather patterns. Knowing how to create weather manipulating contrails comes down to understanding atmospheric temperatures.

This knowledge of contrail creation could be used to intentionally control or change the weather of a region. To create a contrail, the atmosphere where the jet is traveling through must be cold enough so that the jet exhaust freezes into ice crystals. The moisture level must be just right, too, allowing the newly formed ice crystal contrails to persist in the sky for hours.

"Certain regions of the U.S. have more favorable atmospheric conditions for contrails than others," said Jase Bernhardt, a graduate student in geography.

By understanding these prime conditions for contrail creation, intelligence operations could deploy several jets over a region to change the climate of that region.

Whether intentional or unintentional, these large contrails are sometimes seen crisscrossing through the skies like a spider web. Many people call these wide, descending contrails "chemtrails." They could be better called weather modification-heavy metal trails, since the jet exhaust comes from leaded jet fuel.

Contrails can change ground temperature up to 6F

"Research done regarding September 2001, during the three days (following 9-11) when no commercial jets were in the sky, suggested that contrails had an effect," said Andrew M. Carleton, professor of geography. "But that was only three days. We needed to look longer, while jets were in the air, to determine the real impact of contrails on temperature and in terms of climate."

Taking note of these observations, the Penn State researchers delved in deeper to find out if contrails can change the weather. Carleton and Bernhardt investigated several temperature readings at weather stations sites in the South in January and in the Midwest in April. They meticulously compared daily temperature data from contrail sites and non-contrail sites. Both of the sites covered the same amount of land and had equal soil moisture and air mass conditions from the onset.

By the time the researchers were finished, they found a consistent result. A contrail site was tied to lower daytime and nighttime temperatures than a non-contrail site with the same conditions. Contrails decreased the maximum temperature, bringing the daily high and nightly low down several degrees. In the Midwest, the contrail sites depressed the temperature 5F on average. In the South, the temperature drop reached 6F. Remarkably, after the contrails clear up and the next day arrives, the temperatures return to normal. In a way, the contrails act like clouds.

The report states that the "diurnal temperature range was statistically significantly reduced at outbreak stations versus non-outbreak stations." These unforeseen contrail occurrences help explain why weather forecasters are off on their temperature and rain predictions.

"Weather forecasting of daytime highs and lows do not include contrails," said Carleton. "If they were included in areas of contrail outbreaks, they would improve the temperature forecasts."
