Five Millions Tons of Smoke in the Stratosphere | Nuclear Darkness & Nuclear Famine
"Following a war between India and Pakistan, in which 100 Hiroshima-size (15 kiloton) nuclear weapons are detonated in the large cities of these nations, 5 million tons of smoke is lofted high into the stratosphere and is quickly spread around the world.
"A smoke layer forms around both Hemispheres which will remain in place for many years to block sunlight from reaching the surface of the Earth.
"One year after the smoke injection there would be temperature drops of several degrees C within the grain-growing interiors of Eurasia and North America.
"There would be a corresponding shortening of growing seasons by up to 30 days and a 10% reduction in average global precipitation."
