The briefing addresses the recent heatwaves in Europe during May and June, focusing on the number of deaths attributed to these extreme temperatures and the methods used to calculate them. It explains that heat-related mortality is often estimated by analyzing excess deaths—comparing observed fatalities during the heatwave period to expected deaths based on historical data. This approach captures both direct heatstroke cases and indirect deaths, such as those caused by exacerbated cardiovascular or respiratory conditions. The briefing highlights variations in reporting across European countries due to differences in data collection, timing, and criteria for attributing deaths to heat. It also discusses challenges in real-time mortality assessments, including delays in death registration and distinguishing heat-related deaths from other causes. Overall, the briefing emphasizes the importance of consistent methodologies for accurately assessing the human toll of heatwaves, which is critical for public health planning and climate adaptation strategies.
