Ending nuclear weapons, before they end us

Introduction: This editorial emphasises the urgent need to confront the serious threat posed by nuclear weapons, focusing on their devastating effects on health, the environment, and human well-being. It discusses the upcoming vote at the World Health Assembly (WHA) to renew the World Health Organisation's (WHO) mandate to study these impacts, along with a new United Nations (UN) scientific panel that will analyse the risks associated with nuclear war. Main Text: Although the number of nuclear weapons has decreased since the Cold War, today’s global stockpile is still dangerously large. Modernisation efforts and ongoing geopolitical tensions increase the chances they might be used. The editorial points out that nuclear conflict could lead to mass extinction, severe climate change, and widespread famine. It criticises the lack of progress in disarmament and calls for immediate steps, such as adopting "no first use" policies and joining the Treaty on the Prohibition of Nuclear Weapons. The authors encourage health professionals to support the renewed WHO mandate and back the UN panel’s work in gathering current evidence to guide policies and inform the public. Conclusion: The piece frames nuclear disarmament as a critical health issue, emphasising the need for strong political leadership to eliminate these weapons. It appeals to health professionals to rally behind evidence-based policies and the upcoming WHA resolution, pointing out that solid research and public advocacy are essential to prevent disaster.
