Temperature check: greening Australia's warming cities

Australia has always been a country with extreme weather events. This report presents evidence that strong action to increase urban vegetation will become imperative in our three largest cities to reduce serious heatwave impacts by 2060–2080, even with strong climate action.

Urban heat island and overheating characteristics in Sydney, Australia. An analysis of multiyear measurements

It has become increasingly important to study the urban heat island phenomenon due to the adverse effects on summertime cooling energy demand, air and water quality and most importantly, heat-related illness and mortality. The present article analyses the magnitude and the characteristics of the urban...

Mitigating urban heat with green spaces

As cities grapple with the impacts of heatwaves, exacerbated by the urban heat island effect and amplified by climate change impacts, green spaces can cool urban areas, as well as provide health and wellbeing benefits to city dwellers and habitat for biodiversity.
Conference paper

Assessment of heatwave impacts

The frequency and intensity of urban heatwaves (UHWs) have been growing worldwide due to climate change and the exacerbating effects of urban heat islands (UHIEs). UHWs have many negative impacts, including excess negative health outcomes (e.g. morbidity), energy (consumption and peak demand) and water consumption...

Heatwaves and health: guidance on warning-system development

FOREWORD Heatwaves are among the most dangerous of natural hazards, but rarely receive adequate attention. They often lack the spectacular and sudden violence of other hazards, such as tropical cyclones or flash floods. Even the related death tolls are not always immediately obvious. For example...
