Current credible scientific study deals with hurricane, tornado and flood mitigation.5 China is the current lead investor in weather modification and control technology, investing nearly 40 million dollars annually.6 The Chinese
efforts were put on display for the world during the 2008 Summer Olympics.7 The efforts of the Chinese to reduce the amount of rain (by inducing precipitation elsewhere) seemed to work, but
as is a current issue with weather modification, there is not indisputable proof. The military uses of controlling the weather are vast, and future technology will enable more specific control of theweather – actually creating, not modifying the weather."
