摘要

史无前例的 2021 年 "热穹 "对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 例经证实的热致死病例、紧急医疗呼叫翻倍、住院人数增加、基础设施故障以及动植物压力。然而,使用单一的事件后分析方法很难捕捉到极端高温所造成的如此多样的社会经济后果。因此,有必要探索其他方法和数据来源。我们以 2021 年的 "热穹 "事件为案例,利用 5 个订阅新闻数据库中的在线新闻媒体文章(n = 2909)和灰色文献检索进行了事件后分析,以确定极端高温事件对加拿大社会经济的影响。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,其中一些影响是其他数据来源和方法无法识别的。总之,我们表明媒体分析可以补充传统的事后分析方法,并为政府和公共卫生与安全官员提供额外的视角。

Media-Based Post-Event Impact Analysis of the 2021 Heat Dome in Canada.

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.
