Writer provides a series of facts to inform the public and policymakers of the catastrophic consequences of a thermo-nuclear war. The most severe among these consequences is a drastic drop in the world’s temperature. Based on their extensive research, Sagan and his fellow scientists came up with the phenomenon of Nuclear Winter. According to them, heated particles after the nuclear explosion will rise up to form a layer around the earth that will absorb incoming sunlight. Earth, deprived of sunlight, will experience a sharp fall in temperature. This will interrupt photosynthesis and kill livestock that will result in a worldwide shortage of food.

Hence, the article served its purpose in spreading awareness across public and policy makers.
