The provided text outlines the concept of nuclear winter, detailing how a nuclear exchange could lead to a severe, long-lasting climatic disruption. It explains that the catastrophe is not primarily from the blasts themselves, but from the immense fires ignited in urban areas, which would inject vast quantities of soot into the atmosphere. This soot would then block sunlight, causing a global temperature drop, agricultural collapse, and subsequent famine, with impacts lasting decades to millennia. The sources emphasize that modern scientific models consistently show the global and catastrophic nature of these indirect effects, even from a regional conflict, reinforcing the argument for the prevention of nuclear war.
