PROJECT 5.5: Extreme weather hazards in a changing climate
Changes in the intensity and frequency of extreme and hazardous weather events are visible impacts of climate change currently experienced across much of Australia. These events often have important consequences for infrastructure, energy, health and ecosystems. The costs associated with extreme weather hazards and disasters are likely to change in the future as the climate continues to warm.
We’re using observational data, climate models and statistical approaches to improve our understanding of current and future changes to extreme weather hazards and to deliver nationally significant knowledge products on current and future natural hazards. We will focus specifically on tropical cyclones, bush fires, thunderstorms, east coast lows and the extreme weather hazards they can produce.
We’re also consulting directly with stakeholders to ensure our information and knowledge products are incorporated and used to inform effective disaster risk policies and management activities. The improved understanding, information and tools on extreme weather hazards will be provided in formats that are relevant for reducing risks to human health, property and the environment in a changing climate.

This project is contributing to the following climate challenges:
Our research will provide information and tools to inform updated operating and maintenance standards for infrastructure, and reduce the risks to human health, property and the environment.
Our research will provide information and tools for use in decision making in relation to the influence of climate change on extreme weather events and their associated impacts on food security, ecosystems and natural resource management.
Improved information on extreme weather hazards will enhance our ability to provide coastal planners with the information they need to make informed coastal planning and management decisions.
