2026年夏季成为欧洲有记录以来最炎热的季节，打破2003年的历史记录1。这一记录由哥白尼气候变化服务确认1。德国经历了"前所未有"的高温天数，平均约有22个气温超过30摄氏度的高温日和约5个超过35摄氏度的极热日1。
高温导致严重的人员伤亡。截至8月底，至少16300人因热相关原因死亡1。专家指出，这些死亡主要由潜在健康状况因热浪加重所引发1。慕尼黑亥姆霍兹中心气象学家Alexandra Schneider认为部分死者本可活得更久，这不仅仅是"收割效应"1。
除了极端气温本身，持续的热浪与夜间温度难以下降的现象加重了热应激。弗赖堡大学教授Andreas Matzarakis指出："不仅高温重要，持续时间长且夜间温度难以下降也很关键"1。睡眠不足进一步加重了热应激影响。弱势群体因其居住和工作条件较差，在此次热浪中更易遭受伤害1。数据显示，德国平均周温度达到或超过20摄氏度时，热相关死亡风险会增加，而6月22日至28日期间，周平均温度已经超过26摄氏度1。
Europe's summer of 2026 became the warmest season on record, surpassing the previous benchmark set in 2003, according to the Copernicus Climate Change Service 1. The exceptional heat brought devastating consequences, with at least 16,300 heat-related deaths recorded by the end of August, primarily resulting from existing health conditions exacerbated by the extreme temperatures 1.
Germany experienced particularly severe conditions, with an unprecedented number of hot days—averaging approximately 22 days exceeding 30°C and around 5 days surpassing 35°C 1. The danger extended beyond daytime peaks; persistently elevated nighttime temperatures prevented adequate cooling during sleep, intensifying heat stress across the population 1. This continuous thermal strain proved especially harmful to vulnerable populations, whose inadequate housing and working conditions left them disproportionately exposed to the hazard 1.
Andreas Matzarakis, a professor at Freiburg University, emphasized that the threat extended beyond temperature peaks alone: "Not only high temperatures matter, but also their prolonged duration and the difficulty of nighttime temperature decline" 1. Alexandra Schneider, a meteorologist at Munich's Helmholtz Center, offered additional perspective on the mortality toll, suggesting that some deaths represented genuine excess mortality rather than merely accelerated mortality among the already frail—indicating that some victims could have lived longer absent the extreme heat 1.
