Question

The term 'Nuclear Winter' is associated with:
A. Nuclear war
B. Nuclear disarmament
C. Nuclear weapon testing
D. After effect of a nuclear explosion

Answer 1

The catastrophe, the environmental devastation that certain scientists contend would probably result from the many nuclear explosions during a nuclear war.

Complete answer:
-Nuclear winter may be a severe and prolonged global climatic cooling effect hypothesized to occur after widespread firestorms following a nuclear war.
-The hypothesis is predicated on the very fact that such fires can inject soot into the stratosphere, where it can block some direct sunlight from reaching the surface of the world.
-The extreme cold, high radiation levels, and therefore the widespread destruction of commercial, medical, and transportation infrastructures alongside food supplies and crops would trigger a huge price from starvation, exposure, and disease.
So, the correct option is (D).
Additional information:-
The basic explanation for catastrophe, as hypothesized by researchers, would be the various and immense fireballs caused by exploding nuclear warheads. These fireballs would ignite huge uncontrolled fires (firestorms) over any and everyone city and forests that were within range of them. Great plumes of smoke, soot, and mud would be sent aloft from these fires, lifted by their own heating to high altitudes where they might drift for weeks before dropping back or being washed out of the atmosphere onto the bottom. A number of scientists have disputed the results of the first calculations, and, though such a nuclear war would undoubtedly be devastating, the degree of injury to life on Earth remains controversial.

Note: A study published within the Journal of Geophysical Research in July 2007, [140] titled "Nuclear winter revisited with a contemporary climate model and current nuclear arsenals: Still catastrophic consequences", [141] used current climate models to seem at the results of a worldwide nuclear war involving most or all of the world's current nuclear arsenals (which the authors judged to be one almost like the dimensions of the world's arsenals twenty years earlier).
