US Air Force Admits They Can Control the Weather
From the article:
All they need to do is twist a button to change the frequency to microwave range and increase the frequency modulated [FM] transmission power enough to reach and heat up the atmosphere above the target.
The technology is covered under US Patent 4,686,605 on the 'Method and Apparatus for Altering a Region in the Earth's Atmosphere, Ionosphere, and/or Magnetosphere.'
... Walker said this is 'not an area that we have any need for in the future' and it would not be a good use of Air Force research funds to keep HAARP going. 'We're moving on to other ways of managing the ionosphere, which the HAARP was really designed to do,' he said. 'To inject energy into the ionosphere to be able to actually control it. But that work has been completed.'
