evidence: He said: "The amount of energy involved in ionospheric heaters such as HAARP is many orders of magnitude smaller than that involved in solar heating of the earth’s surface and is constrained to a minuscule area. To have any effect on the weather there would need to be some physical phenomena that transferred the energy to the lower atmosphere in a highly non-linear fashion (ie magnify it enormously)." Prof Ward said claims that ionospheric heaters such as HAARP can modulate the weather are "being pushed by people who have no understanding whatsoever of the physics involved in atmospheric circulation and weather systems". [...] The claim that the HAARP facility can control the earth’s weather is false. The facility only interacts with particles in the earth’s ionosphere, well above the range where weather formations occur.
