Artificial Intelligence and Nuclear War Identified as Ultimate Threats to Human Survival
London, Sunday, 11 October 2026.
A global assessment warns that artificial intelligence misuse and nuclear conflict pose potential extinction risks by 2100, though targeted, coordinated action by world leaders can prevent catastrophic outcomes.
Existential Threats Identified for the 21st Century
A newly established commission by The Lancet has released a major assessment identifying 17 catastrophic threats to human health and survival, highlighting the malicious deployment of artificial intelligence and nuclear warfare as leading risks before 2100 [1][2]. The report emphasizes that while these threats pose severe global stability and economic risks, actionable policy frameworks and technological safeguards exist to mitigate each identified danger if world leaders take coordinated action [3]. The findings are being shared on 11 October 2026 at the World Health Summit in Berlin, Germany, marking a critical moment for global health policy [1]. Prof Christopher Murray, commission co-chair and director of the Institute for Health Metrics and Evaluation at the University of Washington, noted that decisions made by leaders today will shape the health and wellbeing of the next generation [1][3].
Quantifying Existential Risk
The commission utilized a disability-adjusted life years (DALYs) metric to rank threats, identifying major catastrophic threats as those exceeding 1 billion cumulative DALYs [1]. Regarding artificial intelligence, the malicious use of AI, including bioweapons, is estimated to cause approximately 10.4 billion years of healthy life lost worldwide by 2100 [3]. In comparison, limiting global heating to 1.8°C rather than 4.4°C could prevent the loss of 1.89 billion years of healthy life, indicating the scale of AI risk is significantly higher than climate mitigation gains alone [1]. The ratio of potential healthy life years lost to malicious AI versus those saved by climate action is 5.503, illustrating the disproportionate impact of technological risks [1][3]. The Lancet editorial board warned that the scale of harm, should these risks be realised, would inflict an apocalypse on humanity [1].
Systemic Vulnerabilities and Aid
Beyond technological and military threats, the assessment identifies 15 other catastrophic threats including air pollution, antimicrobial resistance, and declining overseas aid [1]. A Lancet commission of 35 experts noted that international health aid cuts, seen in the US and UK over the past year, could cause up to 1.5 billion Disability-Adjusted Life Years lost before 2100 [1]. The report argues that recent global shocks, including COVID-19, Ebola Bundibugyo virus disease, and major geopolitical conflict, show how quickly assumptions about stability can be overturned [2][4]. Consequently, governments and multilateral institutions must counter short-termism and localism with systematic, repeatable risk assessment and preparedness planning [2][4].
Pathways to Mitigation
Ibrahim Abubakar, a commission member and professor of infectious disease epidemiology at UCL, stated that the goal is not to scare policymakers but to provide a premise for action where magnitude of difference can be made [1]. The commission advocates that governments must shift away from short-termism toward systematic risk assessment to address threats through 2100 [4]. Dr. Natalia Kanem, former executive director of the United Nations Population Fund and co-chair of the new commission, emphasized that the future is not inevitable and communities must act decisively starting today [3]. The report concludes that achieving meaningful progress will require not only technical solutions but also robust societal and institutional foundations that foster collaboration and accountability [3].
