The theory of 'nuclear winter goes back much more' than 2 decades ago: the recently deceased astronomer Carl Sagan and four colleagues developed the theory of ' nuclear winter, calculating in 1983 the possible effects of a total nuclear attack between the United States and the former Soviet Union.
Now that the nuclear arsenal of the superpowers and 'was reduced considerably after the end of the Cold War "(think that all French nuclear power plants run on uranium dismantled Soviet - source reel oral, oral ie' not I have the link but heard live by its chairman) and is' the issue reconsidered in the face of a possible conflict "regional" in October, North Korea announced that it had tested a nuclear bomb. Even Iran is pursuing nuclear weapons development. Other members or alleged members of the "nuclear club" includes India, Pakistan and Israel.
The study, presented the '11/12 to a meeting of the American Geophysical Union in San Francisco, and' was described as the first detailed document on the climatic effects of nuclear war on a regional scale.
were studied the consequences of two nations who throw themselves at each other a 50-ina-type bombs of Hiroshima over the big cities'. By analyzing population data and distance from the explosion, scientists have predicted that a regional nuclear war would kill 3 million people in Israel up to 17 million people in China. The U.S. would have 4 million deaths due to explosions.
Using modern climate models, researchers say the black pall that would raise the fires would remain in the atmosphere, blocking sunlight and causing a lowering of about 2 degrees Fahrenheit (a little 'more' than 1 degree Celsius) temperatures medium on the surface of the earth in the first three years. Although 'the planet rivedrebbe a gradual warming within a decade, it would still be more' cold as it was previously, scientists say. This cooling
shorten the season suitable for agriculture for about a month in parts of North America, Europe and Asia. Normal cycles of rain as summer monsoons in Africa and Southeast Asia would be affected, causing severe reductions in crop and further poverty '.
