The unprecedented 2021 Heat Dome caused wide-ranging and long-lasting impacts in western Canada, including 619 confirmed heat-related deaths in British Columbia, a doubling of emergency medical calls, increased hospitalisations, infrastructure failures and stress on plants and animals. However, such varied socio-economic consequences of extreme heat can be challenging to capture using a single post-event analysis method. Therefore, there is a need to explore alternative approaches and data sources. Using the 2021 Heat Dome as a case study, a post-event analysis using online news media articles (n = 2909) from 5 subscription news databases and a grey literature search was conducted to identify the socio-economic impacts of the extreme heat event in Canada. The articles reported a wide range of effects to the natural environment (n = 1366), social infrastructure and services (n = 1121), human health (n = 1074), critical infrastructure (n = 988) and the private sector (n = 165). The media-based post-event analysis captured various impacts, some of which have not been identified through other data sources and approaches. Overall, we show that media analysis can complement traditional post-event analysis methods and provide additional perspectives to governments and public health and safety officials.
史无前例的2021年热穹顶事件在加拿大西部造成了广泛而持久的影响，包括不列颠哥伦比亚省619例经确认的与高温相关的死亡病例、紧急医疗呼叫数量翻倍、住院人数增加、基础设施故障以及对动植物造成的压力。然而，使用单一的事后分析方法来捕捉极端高温如此多样的社会经济后果可能具有挑战性。因此，有必要探索替代方法和数据来源。以2021年热穹顶事件为例，利用来自5个订阅新闻数据库的在线新闻媒体文章（n = 2909）进行事后分析，并进行灰色文献搜索，以确定加拿大极端高温事件的社会经济影响。这些文章报道了对自然环境（n = 1366）、社会基础设施和服务（n = 1121）、人类健康（n = 1074）、关键基础设施（n = 988）和私营部门（n = 165）的广泛影响。基于媒体的事后分析捕捉到了各种影响，其中一些影响尚未通过其他数据来源和方法得以识别。总体而言，我们表明媒体分析可以补充传统的事后分析方法，并为政府以及公共卫生和安全官员提供额外的视角。
