The burden of heat-related mortality attributable to recent human-induced climate change
Open accessAbstract
Climate change affects human health; however, there have been no large-scale, systematic efforts to quantify the heat-related human health impacts that have already occurred due to climate change. Here, we use empirical data from 732 locations in 43 countries to estimate the mortality burdens associated with the additional heat exposure that has resulted from recent human-induced warming, during the period 1991–2018. Across all study countries, we find that 37.0% (range 20.5–76.3%) of warm-season heat-related deaths can be attributed to anthropogenic climate change and that increased mortality is evident on every continent. Burdens varied geographically but were of the order of dozens to hundreds of deaths per year in many locations. Our findings support the urgent need for more ambitious mitigation and adaptation strategies to minimize the public health impacts of climate change. Current and future climate change is expected to impact human health, both indirectly and directly, through increasing temperatures. Climate change has already had an impact and is responsible for 37% of warm-season heat-related deaths between 1991 and 2018, with increases in mortality observed globally.

“These studies are often conducted in the climate science disciplines and rarely take the additional step of estimating associated human health impacts9–11.”

The Abstract (Background; page not provided) says there have been limited efforts to conduct detection and attribution analyses in health. The Background on Detection and Attribution Methods (page not provided) contrasts this with the long history of such studies in climate science, supporting the claim that they rarely extend to estimating human health impacts.

The Abstract says previous studies attributed the heatwave to human influence on climate or examined its health effects separately, and describes this study as the first to quantify both together in an event-attribution framework. The Introduction likewise describes tracing anthropogenic influence through to human mortality. This supports the claim that attribution studies rarely take the additional health-impact step.

- Checkable: passes — It can be checked against evidence.
- Load-bearing: fails — The paper’s conclusions may not depend on it.
- Based: passes — The paper gives a reason why it holds.
Probably not a substantial claim. The paper’s conclusions may not depend on it.

No large-scale, systematic studies had already quantified the heat-related health impacts of climate change.
“there have been no large-scale, systematic efforts to quantify the heat-related human health impacts that have already occurred due to climate change.”
The authors state this as an assumption.
The counterfactual climate simulations, driven only by natural forcings, approximate a world without human-induced climate change.
“a counterfactual scenario where climate simulations are driven by natural forcings only, thus approximating the climate that would have occurred in a world without human-induced or anthropogenic climate change16.”
The paper relies on this without support.
The exposure-response functions estimated from observed data apply to the modelled temperature series under both scenarios.
“we used the estimated exposure-response functions to compute the heat-related mortality burden between 1991 and 2018 for each location under two scenarios”
The authors state this as an assumption.
The difference in heat-related mortality between factual and counterfactual scenarios represents the proportion of warm-season deaths attributable to human-induced climate change.
“The difference between the factual and counterfactual scenarios is interpretable as the proportion of total deaths during the warm season attributable to human-induced climate change.”
The paper relies on this without support.
The study is the largest attribution study so far on climate change health impacts.
“To our knowledge, this is the largest attribution study to date on the health impacts of climate change.”
The paper relies on this without support.
The MCC database is the largest consortium of weather and health data assembled so far.
“The observed temperature and mortality data were collected through the Multi-Country Multi-City (MCC) Collaborative Research Network, the largest weather and health data consortium to date (https://mccstudy.lshtm.ac.uk).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
