European Heatwave Highlights Challenges in Estimating Heat-Related Deaths
Europe is currently experiencing an intense heatwave, with countries like Italy, Austria, and France facing extreme temperatures and related challenges. This heatwave has led to health warnings, disruptions in energy and transport systems, and drought-related issues. Scientists are focusing on estimating the human toll of such heatwaves, which is a complex task. Traditional methods rely on 'excess deaths' calculations, comparing death rates during heatwaves to baseline periods. However, this method has limitations, as it cannot distinguish between deaths caused by heat and other factors. An alternative approach uses exposure-response functions, which correlate temperature increases with mortality rates. This method can be applied in real-time and for future scenarios, but requires accurate temperature forecasts.
