Chemtrails---The cobwebs in our sky....

I have been aware of chemtrails for several years.  I had heard of them before but did not do the research until I just couldn't deny how weird the sky looked any longer.  It's a tough one to face, but we're going to have to one way or another.  They aren't even trying that hard to cover themselves up. It's that in your face.
The basic documentary to watch on chemtrails is Aerosol Crimes:

WEATHER MODIFICATION

The third project also utilizes the mixture of barium salts in the atmosphere.

Weather control is a project of the U.S. Air Force and utilizes Nikola Tesla concepts of radio frequency radiation against the ionosphere above the earth and to control the jet stream. (CLICK HERE to visit the official HAARP website.)

Fragile life support systems in our environment are being manipulated, tested, and altered by government for military advantage. Air Force documents implied, "the risks are high but the rewards are worth it." The mixture of barium salts, supporting moisture, is encouraged along the weather fronts and manipulated in a control fashion. It is believed microwave energy is also utilized in the weather control program. Weather data is also a required input to the VTRPE program of the RFMP system.

In the broadest sense, weather control can be divided into two major categories: suppression and intensification of weather patterns. In extreme cases, it might involve the creation of completely new weather patterns, attenuation or control of severe storms, or even alteration of global climate on a far-reaching and/or long-lasting scale. In the mildest and least controversial cases it may consist of inducing or suppressing precipitation, clouds, or fog for short times over a region. Other low-intensity applications might include the alteration and/or use of near space as a medium to enhance communications, disrupt active or passive sensing, or other purposes. The primary areas include generation and dissipation of precipitation, clouds, and fog; modification of localized storm systems; and the use of the ionosphere and near space for space control and communications dominance.

There is a ton of good information at this site as well
