Thin on the right so far
Only 3 of the 25 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
More than 50,000 people are estimated to have died across Europe's cities during the summer heat waves, according to a new analysis. This makes the season the region's deadliest on record for heat-related mortality. The findings, published in the journal Nature Health, suggest that about two-thirds of these deaths, numbering over 32,600, are directly attributed to climate change driven by fossil fuel pollution.
Scientists modelled heat-related deaths between June and August across 854 cities in 30 European countries. They compared temperatures during the summer with those expected in a world without climate change. The death toll is the highest recorded in 26 years and substantially higher than those of previous major European heat waves in 2022 and 2003. While southern and western Europe were most affected, thousands of deaths also occurred in cooler northern regions. The highest death rates were among people aged 85 or older, but thousands of individuals under 65 also died from heat-related reasons.
Disagreement on attribution
While KRDO, citing the study's authors, states that about two-thirds of the deaths are directly attributed to climate change driven by fossil fuel pollution, The Telegraph's digest states that the continent suffered the highest ever heat-related death toll, without specifying the attribution percentage.
What the coverage left out
None of the left, centre, or right-rated digests mention the specific peer-reviewed journal, Nature Health, where the findings were published. The right-rated digest does not specify the proportion of deaths attributed to climate change, unlike the left and centre-rated reports.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
11 rated outlets
- Left-rated reports highlighted the direct link between fossil fuel pollution and the surge in European heat deaths. Inside Climate News stated that "Fossil-Fueled Warming Drives Surge in European Heat Deaths" and that scientists urged governments to expand targeted health measures. The Independent reported that Europe suffered its deadliest summer on record, with several heatwaves occurring. CNN's digest noted that about two-thirds of the deaths could be directly attributed to fossil fuel pollution. The Washington Post's digest mentioned that climate change is responsible for about two-thirds of the additional heat-related deaths, according to researchers. Grist's headline declared Europe's hottest summer was also its deadliest, with researchers attributing most deaths to climate change.

11 rated outlets
- Centre-rated reports focused on the overall death toll and the record-breaking nature of the heat waves. KRDO's headline stated, "‘Worst on record’: Brutal summer heat wave killed more than 50,000 in Europe’s cities," and its full report detailed the estimated deaths, the attribution to climate change, and the age groups most affected. KMIZ's digest echoed KRDO's headline and opening sentences, also noting the attribution of more than 32,600 deaths to climate change. RTÉ's digest reported that over 50,000 people died prematurely due to high temperatures, making it Europe's deadliest summer heat on record.

- The right-rated report from The Telegraph focused on the overall death toll. Its digest stated that the continent suffered the highest ever heat-related death toll, with Italy being the hardest hit.
Questions about this coverage
- How did the left and right cover Europe heat waves killed over 50,000, study estimates?
- Of the 25 outlets on this story carrying a published leaning rating, 44% are rated left, 44% are rated centre, 12% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 30. The sections above set out what each side emphasised, in its own terms.
- Is Europe heat waves killed over 50,000, study estimates left or right?
- Neither side dominates it. Of the 25 rated outlets on this story, 44% are rated left, 44% are rated centre, 12% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of Europe heat waves killed over 50,000, study estimates biased?
- Europe heat waves killed over 50,000, study estimates is one event reported by 30 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Europe heat waves killed over 50,000, study estimates?
- When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered Europe heat waves killed over 50,000, study estimates?
- 30 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- How many people died in Europe's summer heat waves?
- More than 50,000 people are estimated to have died across Europe's cities during the summer heat waves. This figure represents the highest recorded death toll for heat-related mortality in the region over the past 26 years.
- What caused these heat-related deaths?
- About two-thirds of the estimated 50,000-plus deaths are directly attributed to climate change, driven by fossil fuel pollution. Scientists modelled the deaths by comparing temperatures during the summer with those expected in a world without climate change.
- Which age groups were most affected by the heat?
- The highest death rates were observed among people aged 85 or older. However, the analysis also found that thousands of individuals under the age of 65 died from heat-related reasons, highlighting the broad impact of extreme heat.
