A new climate modelling method developed by researchers at the University of Graz in Austria can reportedly calculate the true impact of human-made climate change on extreme weather, offering a more detailed picture of how global warming is reshaping Europe — and underscoring mounting economic, health and environmental costs, according to scientific and media reports.
The model, described as “groundbreaking,” by Euro News, quantifies multiple aspects of extreme events — including frequency, duration, intensity and spatial extent — enabling attribution of climate damage to emission-intensive actors such as nations and corporations. It provides metrics for calculating how much human-driven warming contributes to heatwaves, droughts and floods beyond natural variability.
"Extremity of heat" has increased tenfold since the fifties
The researchers applied their method to historical temperature datasets from 1961–2024 in Austria and across Europe, defining thresholds for “extreme heat” based on a 1961–1990 baseline.
Their findings show that the total extremity of heat in Austria and most of central and southern Europe has increased roughly tenfold in the period 2010–2024 compared to the mid-20th century — a result they say strongly points to anthropogenic climate change - which could cause millions more temperature-related deaths in Europe by 2099, according to an article on Meteo24news.
The study was published in the peer-reviewed journal Weather and Climate Extremes; a preprint of the methodology and results appears on the open repository arXiv under the title Compound event metrics detect and explain ten-fold increase of extreme heat over Europe.
Mounting Human and Economic Toll
The new modelling coincides with independent research showing that recent temperature extremes have had serious human and economic consequences.
During the extreme summer of 2025, heat across much of Europe climbed toward 40 °C, with thousands of heat-related deaths reported. A separate team of researchers at Imperial College London and the London School of Hygiene & Tropical Medicine estimated that climate change was responsible for about 68 % of an estimated 24,400 heat-related fatalities in 854 European cities, raising temperatures by up to 3.6 °C.
Short-term economic losses from the 2025 extreme weather season have been independently estimated at at least €43 billion, with total costs projected to reach €126 billion by 2029 once secondary and compounding impacts — such as simultaneous drought and heatwaves — are accounted for.
Analyses of longer-term European climate losses show that weather-related extremes cost EU economies hundreds of billions of euros over recent decades. For example, between 1980 and 2020, climate-linked extremes resulted in an estimated €487 billion in losses across the EU.
Economic and Policy Implications
Research published this month in Euronews and related climate policy analyses underscore that delays in climate adaptation and mitigation amplify long-term economic risks. A separate study highlighted by European Parliament economists forecast that unmitigated warming could lead to production losses exceeding €5 trillion by 2050, with droughts, heatwaves and floods affecting growth if current emission trajectories persist.
Experts say tools such as the new model from the University of Graz could be crucial for policymakers and financiers aiming to internalise climate risk in economic planning and corporate accountability. Placing a monetary cost on extreme event attribution is thought to help countries and private sectors better assess liability, adaptation needs, and the urgency of accelerating decarbonisation.

In June 2019, high temperatures were peaking, reaching as high as 39—40°C, with Netherlands, Belgium and Germany recording their highest ever temperatures. Paris reached a sweltering 41°C, breaking its previous record in 1947.
The map has been generated using the Copernicus Sentinel-3’s Sea and Land Surface Temperature Radiometer. Whereas weather forecasts use predicted air temperatures, the satellite measures the real amount of energy radiating from Earth – therefore this map better represents the real temperature of the land surface.
