Understanding Global Effects of Nuclear Weapons

About the image


In today’s interconnected world, understanding the cascading global effects of nuclear weapons use is more urgent than ever.

Challenge

Global effects of nuclear weapons use are not well understood and disconnected from nuclear policymaking.

Action

Raise awareness and support novel research on the wide-ranging climatic, economic, humanitarian, and societal effects of nuclear weapons use

Results

Inform nuclear policies and decision making with updated and comprehensive analysis of nuclear effects and promote debate on how effects should be considered in today’s world

The devastating effects caused by a nuclear explosion—light, heat, blast, and radiation—have been known since the Second World War and the bombings of Hiroshima and Nagasaki. However, today’s interconnected world demands updated research and analysis into the global effects of nuclear weapons use, how these effects should inform nuclear policies and postures, and how they should be considered in today’s world.

Global systems have become complex and deeply intertwined, creating new vulnerabilities and increasing the risk of cascading failures with potentially far-reaching consequences for the environment, economy, and modern society. Despite these transformative shifts nuclear policy and decision-making remain largely disconnected from the consequences of nuclear weapons use.

NTI is fostering a global interdisciplinary dialogue to reframe how the effects of nuclear weapons are – and should be – considered in today’s nuclear policy landscape.
