Definition
  1. Noun:
    • A hypothetical, prolonged period of extreme cold, darkness, and environmental devastation predicted to occur following a large-scale nuclear war. The effect would be caused by a global layer of smoke, soot, and dust injected into the atmosphere from firestorms, blocking sunlight and severely disrupting the Earth's climate, potentially leading to the collapse of ecosystems and the perishing of most living organisms.
