2010 Case Study 2 – Extreme Heat Events
This case study provides an analysis of historic and projected changes in extreme heat events on community health. It identifies an historical trend of increasing frequency and intensity of extreme heat events, and projects that this trend will continue.
This case study provides an analysis of historic and projected changes in key temperature variables and extreme heat related indices to improve understanding of the potential impacts of climate change on community health (heat impacts) in the Hunter, Central and Lower North Coast region of NSW.
It identifies existing and projected increasing trends in extreme heat days (>37oC) and yearly worst 3-day heat events. This information has underpinned a broad scale risk assessment process that has identified the following extreme and high rated risks for the region:
- Heat related morbidity and mortality
- Increase in production of photochemical smog and particulate pollution from bushfires
- Reduced access to emergency services and facilities
- Injury, trauma and related effects as a result of violence and trauma
- Disruptions to essential services (eg. electricity & water supplies)
- Reduced access to transport services.
