The aeronomy of the atmosphere between 50 and 110 km. Signals of climate change in the 50 to 110 km height region of the atmosphere are becoming more evident. This region shields the surface from extreme UV radiation and so understanding any changes in the region is important for life. We will improve our understanding of the region and look for additional evidence of changes. We will also contribute to improvements in numerical weather prediction models.
The Response of the Middle Atmosphere to Solar and Dynamical Forcing. The region of the atmosphere and ionosphere between 50 and 100 km is difficult to measure directly. We will use a unique array of instruments deployed across Australia to study how this region responds to waves generated in the lower atmosphere and to changes in electromagnetic energy from the sun and particle precipitation from the magnetosphere. Outcomes will help our understanding of how the region is responding to rising l ....The Response of the Middle Atmosphere to Solar and Dynamical Forcing.

We will use a unique array of instruments deployed across Australia to study how this region responds to waves generated in the lower atmosphere and to changes in electromagnetic energy from the sun and particle precipitation from the magnetosphere. Outcomes will help our understanding of how the region is responding to rising levels of greenhouse gas concentrations. Cooling effects are already apparent and our research will look for additional evidence of change.Read moreRead less

A new flood design methodology for a variable and changing climate. The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance. Monte Carlo simulation tech ....A new flood design methodology for a variable and changing climate. The extreme temporal and spatial variability of Australia's rainfall affects the quantity and quality of water resources, the productivity of agricultural systems, and aquatic and terrestrial ecosystems. Given the impact of extreme events such as floods and the massive investment in water-related infrastructure, evaluation of these risks is an issue of national economic and environmental significance. Monte Carlo simulation techniques will quantify the risks associated with current and future climate change, and the combined risks that come from multiple sources, such as from coastal tides and storm runoff. This research will provide a new spatial framework for calculating risk as well as tools to evaluate flood risk.Read moreRead less
Using ancient DNA to understand Australia's past and manage its future. The aim of this program is to establish an ancient DNA research centre for Australia, and use long-term natural records to investigate the genetic responses of animals, plants, and micro-organisms to environmental change.

There is growing international and national concern over the possible environmental, economic and social impacts of global and regional climate change. This project brings together a multi-disciplinary team of internationally recognised research leaders and the resources they command to investigate the environmental impacts of climatic changes in the Nile basin over geologically recent times. The outcome will be a more comprehensive understanding of how a major river system responds to global and regional climate change, and will provide an enhanced conceptual basis for anticipating how drainage systems such as the Murray-Darling could respond to future change.Read moreRead less
Using ancient DNA to investigate the environmental impacts of climate change and humans through time. This project will provide important information about how climate change and human impact have effected our environment over the past 50,000 years, removing many of the large mammals and altering the landscape.

This project will provide important information about how climate change and human impact have effected our environment over the past 50,000 years, removing many of the large mammals and altering the landscape. It is critical that the background to our current environment is properly understood if we are to predict the effects of on-going changes such as global warming. The research will concentrate on the effects of climate change on large mammals in North and South America, New Zealand, Australia and Africa over this time period, and will examine the additional impact of humans in each location.Read moreRead less
Towards Distributed Phased Array Radar for High Resolution Weather Monitoring. Several recent reports on climate change by leading international and national bodies forecast that the rate of weather hazards such as storms and wind-shear, and of weather-associated phenomena such as bush fires will increase over the next 40 years.

Several recent reports on climate change by leading international and national bodies forecast that the rate of weather hazards such as storms and wind-shear, and of weather-associated phenomena such as bush fires will increase over the next 40 years. The current technology for monitoring weather events, and effects like wind-shift, which has a serious impact on dangers associated with bush fires, has significant weaknesses. We will deliver considerable improvements in monitoring capability by developing the technology for using a network of small phased array radars. We aim to place monitoring resources where end-user needs are greatest.Read moreRead less

Summary
A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, an ....A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, and directly measures past temperatures. This will have a profound effect on our understanding of environmental changes on both short and long time scales, and permit a better understanding of the hydrological balances within the landscape.Read moreRead less
Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia.

More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exploitation and habitat alteration by ancient people, and the influence of dramatic climatic shifts on the Australian biota. Information on past biological responses to environmental change is critical to properly contextualising the current impact, and long-term consequences of, threats such as global warming, habitat loss and invasive species.Read moreRead less
