  1. Nuclear winter

    Nuclear winter is a severe and prolonged global climatic cooling effect that is hypothesized to occur after widespread firestorms following a large-scale nuclear war. The hypothesis is based on the fact that such fires can inject soot into the stratosphere, where it can block some direct sunlight from reaching the surface of the Earth. It is speculated that the resulting cooling would lead to widespread crop failure and famine. When developing computer models of nuclear-winter scenarios, researchers use the conventional bombing of Hamburg, and the Hiroshima firestorm in World War II as example cases where soot might have been injected into the stratosphere, alongside modern observations of natural, large-area wildfire-firestorms.


  1. nuclear winter

    Nuclear winter is a theoretical environmental condition that scientists predict could occur after a large-scale nuclear war. It is described as a severe and prolonged temperature drop on Earth due to the damage caused to the atmosphere by the smoke and soot rising from the firestorms following nuclear explosions. This condition could destroy most of Earth's vegetation, lead to mass extinction, and make the planet uninhabitable.


  1. Nuclear winter

    Nuclear winter is a hypothetical climatic effect of countervalue nuclear war. Models suggest that detonating nuclear weapons could have a profound and severe effect on the climate causing cold weather and reduced sunlight for a period of months or even years if the nuclear weapon strikes are on cities, comparable to Hiroshima, where it is modelled that large amounts of smoke and soot would be ejected into the Earth's stratosphere. Similar climatic effects can be caused by comets or an asteroid impact, also sometimes termed an impact winter, or by a supervolcano eruption, known as a volcanic winter.
