Lancet Commission Names 17 Threats to Global Health Through 2100, With Obesity the Largest by Burden
Launched at the World Health Summit in Berlin, the assessment counts avoidable lost healthy life to 2100 and puts nuclear conflict and malicious AI top for extinction risk, but is no ranking.

A new Lancet commission has listed 17 threats that could shape human health to the end of this century, and it puts two of them, nuclear conflict and the malicious use of artificial intelligence, in a category of their own because they carry a non-zero risk of extinction. The Lancet Commission on 21st Century Global Threats to Health was published on 12 October and launched at the World Health Summit in Berlin, News-Medical reported. The co-chairs are Christopher Murray of the Institute for Health Metrics and Evaluation and Natalia Kanem, the former head of the UN Population Fund.
The authors stress that this is not a prediction of extinction and not a league table. They say the list is meant to show where action could help most.
How does the commission measure a threat?
The team looked at hundreds of possible threats across 204 countries and territories and kept 17 that could account for at least one billion disability-adjusted life years by 2100, had enough data to model and could be changed by policy. A DALY is one year of healthy life lost. For each threat they modelled a best and a worst plausible future, and the gap between them is the "amenable" burden, the harm that action could realistically avoid, according to News-Medical.
Health Policy Watch adds that each threat's score reflects the healthy life it would destroy multiplied by the chance it happens, and that the AI and nuclear figures rest on expert judgment and superforecasters rather than historical data.
Which threats come out largest?
Obesity is the biggest by cumulative burden, at about 23 billion amenable DALYs, and the leading threat in 154 of the 204 countries and territories, Health Policy Watch said. Low educational attainment follows at 16.1 billion and income inequality at 13.8 billion, roughly 25 COVID-19 pandemics by News-Medical's comparison. Malicious AI is put at 10.4 billion, with a very wide uncertainty range, and nuclear conflict at 9.35 billion. Preventing nuclear conflict could avert an estimated 133 million deaths by 2100. Climate change is estimated at 1.89 billion, while childhood malnutrition, at just over one billion, sits near the bottom of the list.
On extinction, the commission cites superforecasters at 0.4 per cent for AI-driven extinction by 2100 and AI specialists at 3 per cent. Asteroids and supervolcanoes were left out as too unlikely before 2100.
What do critics and the authors say?
Critics argue the list can mislead. Health Policy Watch quotes Melissa Jimenez Gomez Tagle saying the climate estimate omits tipping points, and the commission itself says the figures should not be read as priorities. Euronews reports the recommendations: build threat-ready health systems, invest in breakthroughs where current tools fall short, and track threats through regular reassessment, with the assessment to be updated annually.
This article is reporting on a published commission, not medical advice. Its figures are modelled projections, and decisions about weight, medication, diet or any treatment belong with a clinician who knows your history.
The next test is whether governments treat the commission as a planning tool. The authors plan an annual update, so the first answer on whether the list moves anyone should come within a year.
