“In discussing the state of the atmosphere following a nuclear exchange, we point especially to the effects of the many fires that would be ignited by the thousands of nuclear explosions in cities, forests, agricultural fields, and oil and gas fields. As a result of these fires, the loading of the atmosphere with strongly light absorbing particles in the submicron size range (1 micron = 10-6 m) would increase so much that at noon solar radiation at the ground would be reduced by at least a factor of two and possibly a factor of greater than one hundred.”

Source Report: Nuclear Winter Study, 1980s

Massive fires from nuclear detonations would fill the sky with tiny, light‑blocking particles, cutting sunlight at the surface by half or more, potentially to a hundred‑fold reduction.

In simple terms: Nuclear fires would darken the world, cutting sunlight drastically.
