New Document Reveals Military Mystery's Powers

Since its inception, there's been a huge range of opinion on what HAARP actually does: everything from a giant mind control facility to a space nuke countermeasure to a weather controller to an ionosphere-boiling mad science experiment to the mother of all pork projects has been suggested. But now that the program is actually up an running, military managers say the electronics array has much more benign use. "HAARP's main job is to produce radio waves to probe the ionosphere," an Air Force Research Laboratory officer said in October.

Weather Warfare: Beware the US military’s experiments with climatic warfare

Environmental modification techniques have been applied by the US military for more than half a century. US mathematician John von Neumann, in liaison with the US Department of Defense, started his research on weather modification in the late 1940s at the height of the Cold War and foresaw ‘forms of climatic warfare as yet unimagined’. During the Vietnam war, cloud-seeding techniques were used, starting in 1967 under Project Popeye, the objective of which was to prolong the monsoon season and block enemy supply routes along the Ho Chi Minh Trail.

The US military has developed advanced capabilities that enable it selectively to alter weather patterns. The technology, which is being perfected under the High-frequency Active Auroral Research Program (HAARP), is an appendage of the Strategic Defense Initiative – ‘Star Wars’. From a military standpoint, HAARP is a weapon of mass destruction, operating from the outer atmosphere and capable of destabilising agricultural and ecological systems around the world.
