The predicted climate condition resulting from a large scale
nuclear war. The explosions would launch enormous amounts of particles of dust and
soot into the
stratosphere, and the ashes could remain there for weeks to years. The sunlight would be blocked, and the combination of darkness, cold, radiation, and destruction of world infrastructure by the nuclear bombs could easily wipe out much plant life, including necessary crops. This would in turn cause starvation up through the food chain, eventually causing a massive exctinction of all life on the planet.
North Korea, America, Pakistan, India, Russia, and
China all launched nuclear bombs to counter
the enemy's nuclear bombs, causing a
nuclear winter in just two days. Eight weeks later, every human was dead.
