Nuclear winter (also known as atomic winter) is a hypothetical climatic effect of nuclear war. It is theorized that detonating large numbers of nuclear weapons has a profound and severe effect on the climate causing cold weather and reduced sunlight for a period of months or even years, especially over flammable targets such as cities, where 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.

Famous quotes containing the words nuclear and/or winter:
“The emotional security and political stability in this country entitle us to be a nuclear power.”

“When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter ... decent weeds, at least, which widowed Nature wears.”
—Henry David Thoreau (1817–1862)
