The important debate on global warming sponsored by the United Nations provides only a partial picture of climate change over the devastating impact of emissions of greenhouse gases in the ozone layer , the world's climate can now be changed as part of a new generation of sophisticated "non-lethal weapons" (non-lethal-weapons). Both the Americans and the Russians have developed capabilities to manipulate the world's climate. In the U.S., the technology has been developed within the program "High-frequency Active Aural Research" (HAARP) as part of the Strategic Defense Initiative. Recent scientific evidence suggests that HAARP is fully operational and has the potential to cause floods, droughts, hurricanes and earthquakes.
