Weather Warfare is the follow-up book to Jerry E. Smith's HAARP: The Ultimate Weapon and covers the 130-year history of military, scientific and commercial efforts at controlling Mother Nature.
The furor over cloud seeding above the Ho Chi Min Trail during the Viet Nam War lead to a 1978 UN treaty banning the use of all environmental processes (weather, earthquakes, tidal waves, etc.) as weapons of war.
After signing that treaty US research allocations dropped from $140 million a year to zero - did Uncle Sam really abandon this research or did the whole program go "black"?
A lengthy chapter on the High-frequency Active Auroral Research Program (HAARP) contains the most up to date material now available in book form, including how it might have played a role in the destruction of the Space Shuttle Columbia.
Smith spends 100 pages on "chemtrails" focusing on "geoengineering" - a scheme to use particles intentionally released into the upper atmosphere to mitigate global warming.
