热浪是气候引起的死亡的主要原因之一。我们以欧洲、美国和亚洲最近发生的热浪为例，说明仅基于温度图来传达危险状况如何会导致社会对健康风险的认识不足。将每日最高温度值与考虑温度和湿度影响的生理热应激指数进行比较，说明了这些近期事件期间各自峰值的地理范围和时间存在显着差异。这表明需要重新审视如何传达气象热浪及其预期影响。气候和医学界需要密切合作，选择最佳的热应激指标，建立可操作的指标，并向公众介绍。
Heatwaves are one of the leading causes of climate-induced mortality. Using the examples of recent heatwaves in Europe, the United States and Asia, we illustrate how the communication of dangerous conditions based on temperature maps alone can lead to insufficient societal perception of health risks. Comparison of maximum daily values of temperature with physiological heat stress indices accounting for impacts of both temperature and humidity, illustrates substantial differences in geographical extent and timing of their respective peak values during these recent events. This signals the need to revisit how meteorological heatwaves and their expected impacts are communicated. Close collaboration between climate and medical communities is needed to select the best heat stress indicators, establish them operationally, and introduce them to the public.
