Environmental modification techniques (ENMOD) for military use constitute, in the present context of global warfare, the ultimate weapon of mass destruction.

Rarely acknowledged in the debate on global climate change, the world’s weather can now be modified as part of a new generation of sophisticated electromagnetic weapons. Both the US and Russia have developed capabilities to manipulate the climate for military use.

Environmental modification techniques have been applied by the US military for more than half a century. US mathematician John von Neumann, in liaison with the US Department of Defense, started his research on weather modification in the late 1940s at the height of the Cold War and foresaw ‘forms of climatic warfare as yet unimagined’.
