Researchers from the Institute for Health Metrics and Evaluation (IHME) and 34 other leaders have released a landmark report in The Lancet identifying 17 “catastrophic threats” to global health and wellbeing for the remainder of the 21st century. The commission, chaired by Dr. Christopher Murray of the University of Washington and former UN Population Fund executive Dr. Natalia Kanem, warns that without coordinated action, these threats could erase tens of billions of years of good health worldwide.
Key threats and projected impact
The report groups the dangers into three categories: health conditions and behaviors (such as obesity, high blood pressure, smoking and mental‑health disorders), broader socioeconomic and environmental forces, and technology and conflict. Among the 17, two pose an extinction‑level risk: nuclear conflict and the malicious use of artificial intelligence.
Using IHME’s Global Burden of Disease data, the commission estimates that the cumulative loss of healthy life years from all 17 threats could reach “tens of billions” by the end of the century if current trends continue. Malicious AI alone could account for about 10.4 billion years of lost health, a figure comparable to the impact of natural pandemics and the worldwide obesity epidemic.
Why AI matters
Recent statements from AI developers, including an IPO filing by Anthropic, have warned that advanced AI systems could present a “catastrophic or existential risk to humanity.” While the commission notes that no global‑scale AI disaster has yet occurred, the theoretical risk is significant enough to merit inclusion alongside nuclear war.
Forecasters consulted by the report acknowledge wide divergence in estimating AI‑related catastrophe, reflecting the uncertainty inherent in modeling a technology still in rapid evolution. Nonetheless, the commission stresses that the potential for rapid, destabilizing events underscores the need for pre‑emptive governance.
Obesity and other behavioral risks
Unlike AI, the health impacts of obesity are grounded in extensive empirical data. The commission cites rising rates of overweight and obesity in every country, projecting that by 2050 as many as 60 % of adults and one‑third of children could be affected. This surge drives a cascade of related conditions—cardiovascular disease, diabetes, certain cancers—and contributes substantially to the overall burden of lost healthy years.
Call to action for leaders
Dr. Murray emphasizes that “humanity still has the agency to act.” He urges world leaders to treat the commission’s findings as a roadmap for targeted interventions, noting that delaying action will simply shift costs to future generations. The report highlights seven additional factors that will shape societal response, including trust, collaborative global leadership, resilient food systems and equitable societies.
“Public health is full of examples in which potential threats were known, and protection plans were in place, yet effective action failed,” the commission writes. It argues that meaningful progress will require not only technical solutions but also robust institutional foundations that foster collaboration and accountability.
Implications for policy and communities
The commission’s authors stress that the greatest burden of these threats falls on the most vulnerable communities. By focusing on trust‑building, equitable resource distribution and coordinated policy, governments can mitigate the disproportionate impact on low‑income families and rural areas.
While the report does not prescribe specific legislation, it calls on national, regional and local authorities to develop comprehensive strategies that address each threat’s unique drivers. In the words of Dr. Kanem, “Governments and communities must act decisively starting today, to protect health and build a fairer, more peaceful and more secure future for the coming generations.”
