Nuclear winter is a severe and prolonged global climatic cooling effect that is hypothesized [1] [2] to occur after widespread firestorms following a large-scale nuclear war. [3] 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.
An impact winter is a hypothesized period of prolonged cold weather due to the impact of a large asteroid or comet on the Earth's surface. If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere , blocking the radiation from the Sun .
Nuclear famine is a hypothesized famine considered a potential threat following global or regional nuclear exchange.It is thought that even subtle cooling effects resulting from a regional nuclear exchange could have a substantial impact on agriculture production, triggering a food crisis amongst the world's survivors.
The Year Without a Summer was an agricultural disaster; historian John D. Post called it "the last great subsistence crisis in the Western world". [4] [5] The climatic aberrations of 1816 had their greatest effect on New England (US), Atlantic Canada, and Western Europe.
Nuclear security remains an essential function, meaning the Department of Energy's National Nuclear Security Administration would continue maintaining nuclear weapons. Do national parks close ...
(Bloomberg) -- Germany’s last few remaining nuclear reactors could keep operating through the winter even though they are poised to close permanently by the end of this year, according to ...
Winter, which is warming faster than any other season for much of the US, seems to be making a comeback for the first time in years; this January was the coldest in the Lower 48 since 1988.
It makes dramatic long-lasting climate predictions of the effect a nuclear winter would have on the Earth, an event that is suggested by the authors to follow both a city countervalue strike during a nuclear war, and especially following strikes on oil refineries and fuel depots.
