Climate-change projections suggest that European summer heatwaves will become more frequent and severe during this century1–4, consistent with the observed trend of the past decades5,6. The most severe impacts arise from multi-day heatwaves, associated with warm night-time temperatures and high relative humidity. Here we analyse a set of highresolution regional climate simulations and show that...

As the frequency and intensity of heatwaves are growing in Australia, strategies to combat heat are becoming more vital. Cities are exposed to urban heat islands (UHIs) due to excess urbanisation. In this study, a definition of urban heatwave (UHW) is conceptualised to investigate the combined impacts of heatwaves and UHIs. To quantify the negative impacts of UHW, indicators—such as excess morb...

STUDY OBJECTIVE This study investigated the relation between heat and mortality in London to determine the temperature threshold at which death rates increase and to quantify the effect of extreme temperatures on mortality. DESIGN Daily data on all cause mortality and temperature were obtained for a 21 year period and the relation between them investigated both graphically and by using non-pa...

Background: Previous studies have shown that heatwaves are associated with increased mortality. However, it remains unclear whether the associations between heatwaves and mortality are modified by the environmental quality. Methods: We used the United States (US) Environmental Protection Agency's Environmental Quality Index (EQI) and its five domain indices (air, water, land, built, and sociode...

Results Syndromic surveillance reporting Routine weekly surveillance bulletins are produced from each syndromic system: these reports present the current indicator trends and encapsulate the main summary findings from the weeks surveillance, providing a number of key messages for health professionals.1 Heatwave surveillance Syndromic surveillance plays an important part in assessing the health ...

BACKGROUND Heatwave warning systems aim to assist in reducing health effects during extreme heat. Evaluations of such systems have been limited. This study explored the effect of a heatwave warning programme on morbidity and mortality in Adelaide, South Australia, by comparing extreme events in 2009 and 2014, the latter with exposure to the preventive programme. METHODS The health outcomes du...

OBJECTIVES To assess the heterogeneity of heatwave-related impacts on mortality across different cities. DESIGN A multicity time series study. SETTING 3 largest Australian cities: Brisbane, Melbourne and Sydney. PARTICIPANTS All residents living in these cities. MAIN OUTCOME MEASURES Non-external causes mortality data by gender and two age groups (ie, 0-75 and 75+) for these cities duri...
