The High Frequency Active Auroral Research Program (HAARP) is a research program in Alaska that uses radio waves to study the atmosphere. The remote facility comprises 180 antenna masts and was originally set up by the US military. Today it is operated as an independent research station by the University of Alaska. Howev- er, conspiracy theorists believe that this is just a cover. In reality, so they say, the electromagnetic signals are used to trigger droughts, storms, floods and hurricanes in hostile states and to control the minds of the world‘s population.

What makes these claims quite implausible is the fact that HAARP is not very secret for a covert facility. Moreover, its signals are far too weak to have any effect on the brain or even the weather.
