Hydrological changes in Australia and the South Pacific. This project plans to use stalagmites from the South–West Pacific to generate continuous rainfall records for the last 2000 years. Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in ....Hydrological changes in Australia and the South Pacific. This project plans to use stalagmites from the South–West Pacific to generate continuous rainfall records for the last 2000 years. Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in the Pacific. This knowledge would increase our scientific understanding and enable better predictions of the recurrence of droughts and wet events in Australia.Read moreRead less
Reconstructing changes in atmospheric circulation over the mid-latitudes of the Southern Hemisphere during the past 3000 years. The climate of the mid-latitudes of the southern hemisphere is of global significance and yet past changes have proved difficult to reconstruct due to the dearth of records. Working across the Southern Ocean region using tree rings, lake sediments and ice cores, the project will produce the first comprehensive reconstruction spanning the last 3000 years.
Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Austra ....Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Australian-led international project aims to determine the mechanisms and impacts of past interglacial Antarctic warming up to 2°C (relative to pre-industrial). Innovative techniques integrating horizontal ice cores and high resolution marine records will help identify polar tipping points and better plan for impacts in Australia.Read moreRead less
Taxation, family policy and pension reform in an uncertain economy. The policies with which this research is concerned are central in determining the well being of millions of Australians in both current and future generations. It is important that these policies be debated and formulated on the basis of the best possible conceptual framework and with the most reliable possible quantitative assessments of their effects. It is also important that the policies concerned be considered jointly rathe ....Taxation, family policy and pension reform in an uncertain economy. The policies with which this research is concerned are central in determining the well being of millions of Australians in both current and future generations. It is important that these policies be debated and formulated on the basis of the best possible conceptual framework and with the most reliable possible quantitative assessments of their effects. It is also important that the policies concerned be considered jointly rather than in isolation from each other. The work will therefore directly assist policy makers in this area. Since it will be at the leading edge of current research, it will also benefit Australia's standing in the international research community.Read moreRead less
Robust Empirical Analysis of Poverty and Inequality in Australia. The project aims to improve our understanding of economic poverty and inequality in Australia, and contribute new method to the field of distributional analysis. The empirical analysis of consumption poverty and inequality will highlight the critical methodological assumptions underlying our perceptions of poverty, and provide an evaluation of the effectiveness of a range of programs targeted to the poor.

The project aims to improve our understanding of economic poverty and inequality in Australia, and contribute new method to the field of distributional analysis. The empirical analysis of consumption poverty and inequality will highlight the critical methodological assumptions underlying our perceptions of poverty, and provide an evaluation of the effectiveness of a range of programs targeted to the poor. The analysis of economic inequality in Australia will determine if recent trends are due to increasing globalisation, and whether national programs were effective in ameliorating international influences. This research will ultimately contribute to more effective poverty alleviation and income support programs.Read moreRead less

First, the collaboration of researchers across institutions, and internationally, will enhance and promote Australian research skills. Second, Australian research will be will be placed at the forefront of an important, international field. Third, the research will make fundamental contributions to the evidence base for the design of public policies to ensure Australians have access to adequate resources in retirement. This is an urgent public policy concern due to the rapid ageing of the Australian population: the fraction aged over 65 years is forecast to double from 10% to 20% over the next 40 years.Read moreRead less
Risks of rapid ocean warming at the Antarctic continental margin. This project aims to comprehensively understand the interconnected processes by which oceanic heat is circulated towards Antarctica. The risk of rapid ocean warming at the Antarctic margin is profound, with change already detected via deep ocean warming, land-ice melt, and ice shelf collapse. Yet this region remains poorly understood, with only limited observations due to both a harsh environment and a lack of standard data stream ....Risks of rapid ocean warming at the Antarctic continental margin. This project aims to comprehensively understand the interconnected processes by which oceanic heat is circulated towards Antarctica. The risk of rapid ocean warming at the Antarctic margin is profound, with change already detected via deep ocean warming, land-ice melt, and ice shelf collapse. Yet this region remains poorly understood, with only limited observations due to both a harsh environment and a lack of standard data streams. This project will use high-resolution global and regional ocean/sea-ice models to examine mechanisms for rapid warming of Antarctic continental shelf waters via both large-scale drivers and fine-scale processes, including mesoscale eddies, tide-topography interactions, and bottom boundary flows. This work will better constrain future rates of ice melt around Antarctica by providing vital knowledge of the ocean processes, dynamics, and feedbacks relating to warm water intrusion onto the Antarctic continental shelf.Read moreRead less

Our research aims to answer fundamental geomorphic questions about the future of coral reefs, focusing on the Great Barrier Reef (GBR). We will develop cutting-edge, fully open-source numerical models to quantify the eco-morphodynamic evolution of the GBR under IPCC climate-change scenarios. Our geomorphic numerical models will consider biotic/abiotic feedbacks including synergistic effects of multiple stressors such as waves, temperature, acidification and sediment transport, at individual reef scales. We will model the future of the GBR’s ecosystem-services, allowing for a quantum leap in the geomorphic knowledge and understanding of coral reef ecosystems. Expected outcomes include a gamechanger tool for future management of the GBR.Read moreRead less
Examining the vulnerability of ocean carbon biogeochemistry in a high CO2 world. Rising CO2 levels in the atmosphere from human activity is changing the biogeochemistry of the ocean, with large potential consequences on future atmospheric CO2. This work will explore these changes and will result in a more complete understanding of how the ocean will either accelerate or delay the increase in atmospheric CO2.
