Global dimming; Gespenster; All you have to do is look up into the skies and see the jets that streak those skies with "X" and parallel line patterns of long-lasting, dispersing clouds that transform the skies into a hazy, yellowish gray by late afternoon, often most concentrated in the horizon of the setting sun. It is already taking place in *addition* to man-made pollution and much of it seems to be deliberate. This is accomplished by lacing the contrails of jets with barium and aluminum salts, polymer fibers, thorium, or silicon carbide, this is documented. The addition of these compounds to the water-vapor/jet exhaust discourages water droplet aggregation, leaving smaller water droplet nuclei that are lighter and able to persist longer, allowing a prolonged dissipation and dispersion, effectively forming a "filter" between the sun and the earth. This has the effect of decreasing the amount of UV radiation reaching the earth's surface, hence a cooling phenomenon occurs near the surface and results in lower surface temperatures. There has long been speculated effects on the weather that result from this phenomena in the form of drought and decreased precipitation. It would follow that it would be possible through a concerted effort to create artificial cloud cover that could inhibit natural events like hurricanes for instance, by the manipulation of surface temperatures, where less warm surface air would be able to mix with atmospheric cooler air, discouraging storm cloud formation. This takes place all over the Northern hemisphere with the exception of China which has *not* signed on the the "Open Skies" treaty which entered into force on January 1, 2002, and currently has 34 states parties. It allows unmanned aircraft from neighboring nations to enter surrounding countries airspace with prior notification in a cooperative effort to reduce global warming amongst other controversial objectives. The natural consequence and perhaps the *most* compelling reason that such an effort has been undertaken by many countries of the northern hemisphere would be to counter the effects of global warming. Other reasons include experimentation by using facilities such as HAARP, The High Frequency Active Auroral Research Program (HAARP) which is an investigation project jointly funded by the United States Air Force, the United States Navy, the University of Alaska, and the Defense Advanced Research Projects Agency. Although widely argued, in essence this project is capable of "ionizing" portions of the atmosphere (e.g. Ionosphere) for military applications.
