Discussion of the Effects of Nuclear War

Against a backdrop of increased tension among the world’s major powers,

the risks and effects of nuclear war have received growing interest in
recent years. These topics were discussed at the highest political and
scientific levels during the Cold War. They are now back front and center,
even though the world and the type of nuclear risks it faces have changed
in many ways since. Last year, the US National Academies of Sciences,
Engineering, and Medicine published its long-awaited report on the
environmental impacts of nuclear war. The last time it did such a
comprehensive study was in … 1985. Also, an independent scientific panel
mandated by the United Nations is preparing to submit a report on the
effects of nuclear war to the UN General Assembly next year. The UN never
had a scientific panel dedicated to the issue. Meanwhile, new research
based on the most advanced climate models is bringing new insights into the
understanding of the global effects of nuclear war. And nuclear war
scenarios are evolving, beyond the all-out nuclear exchange between the two
Cold War superpowers to include more complex scenarios of limited nuclear
exchange involving smaller arsenals—but with the inherent risk of
escalation.
