Nuclear Winter
Nuclear winter (also known as atomic winter) is a hypothetical climatic effect, most often considered a potential threat following a countervalue, or city-targeted, nuclear war. Climate models suggest that the ignition of 100 firestorms that are comparable in intensity to that observed in Hiroshima in 1945 would produce a small nuclear winter. The burning of these firestorms would result in the injection of soot(specifically Black carbon) into the Earth's stratosphere, producing an anti-greenhouse effect, that lowers the Earth's surface temperature. With the models concluding that the size of this effect, from the cumulative products of 100 of these firestorms, would unmistakably cool the global climate by approximately 1 °C for two to three years; with which the authors speculate, but do not model, would have global agricultural losses as a consequence. source: Wikipedia
