Testing a new explanation of cloud feedback on global climate. A new analysis suggests that the sensitivity of global climate to greenhouse gases is largely controlled by the upward transport of water vapour in the lower troposphere, but the analysis did not examine clouds, which must be involved for the mechanism to be valid. The aim of the proposed project is to determine whether variations in cloud implied by this new explanation are supported by observations and process models. If the explan ....Testing a new explanation of cloud feedback on global climate. A new analysis suggests that the sensitivity of global climate to greenhouse gases is largely controlled by the upward transport of water vapour in the lower troposphere, but the analysis did not examine clouds, which must be involved for the mechanism to be valid. The aim of the proposed project is to determine whether variations in cloud implied by this new explanation are supported by observations and process models. If the explanation is confirmed, then for the first time in over 30 years of intense research it will be possible to determine the long-term severity of global warming by examining the present-day atmosphere. The expected outcome of this research is to clarify how and why low clouds change in altered climates.Read moreRead less
New insights into abrupt climate change using isotope model-data fusion. There have been several episodes in the past 60,000 years during which carbon dioxide was released into the atmosphere causing significant and rapid warming. This project aims to determine the source of the carbon responsible for these warming events. This project is significant because it will increase our understanding of the processes underlying abrupt past, and potential future changes. These processes are currently und ....New insights into abrupt climate change using isotope model-data fusion. There have been several episodes in the past 60,000 years during which carbon dioxide was released into the atmosphere causing significant and rapid warming. This project aims to determine the source of the carbon responsible for these warming events. This project is significant because it will increase our understanding of the processes underlying abrupt past, and potential future changes. These processes are currently underestimated or missing in climate models. The expected outcomes include a better understanding of the non-linear responses in the climate system. This should provide significant benefits, such as an assessment of whether the smooth climate changes currently projected through to year 2100 are misleading.Read moreRead less

Our econometric analysis will provide new evidence on the short term goals pursed by central banks and improve our understanding their trade-offs. One application of our results will be an improvement in the ability to measure ....Evaluation of targeting rules for implementing monetary policy. Monetary policy plays a primary role in stabilising business cycle fluctuations and in mitigating the effects of large economic shocks. This research deals with key issues in the operation of monetary policy. Our econometric analysis will provide new evidence on the short term goals pursed by central banks and improve our understanding their trade-offs. One application of our results will be an improvement in the ability to measure and evaluate the performance of central banks. Greater evidence on the objectives and constraints of central banks will increase public knowledge and understanding of monetary policy, leading to more effective policy. Read moreRead less

Our project will provide an important, innovative and comprehensive examination of globalization and its economic effects. In addition to making novel theoretical and empirical contributions, it will also facilitate meaningful analyses of policy issues in Australia.Read moreRead less
When the ice melts: a new perspective on the causes of Quaternary glacial terminations. The project will assemble an unprecedented palaeoclimate time series extending back to 1.2 million years ago that will allow marine and ice core records to be placed onto an absolute time scale. This will allow testing of fundamental hypotheses on why the Earth's climate shifts from glacial to interglacial states, with flow-on effects to climate models.
The Demand for Older Workers: Technology, Skill and Employment Opportunities. "Productive ageing" policies are central to Australia's strategies for the governance of population ageing. But little is known about the determinants of firms' demand for older workers. By uncovering the impact that technological change has on firms' hiring and training decisions, this study will critically complement our understanding of older workers' constrained employment opportunities.

"Productive ageing" policies are central to Australia's strategies for the governance of population ageing. But little is known about the determinants of firms' demand for older workers. By uncovering the impact that technological change has on firms' hiring and training decisions, this study will critically complement our understanding of older workers' constrained employment opportunities. In so doing it seeks to inform the long-term policy debate on how best to adjust our economy to the current major demographic and technological development. Its outcomes will be of interest and use to policy makers, industry, advocacy groups, unions and the wider community.

This project will provide improved methods to inform Australia's macroeconomic policies and its strategies for economic development by suggesting the most adequate structural macroeconomic model for the Australian economy. Effective macroeconomic policies, in turn, assure stable economic development, smoothes effects of economic cycles and balances inflation, unemployment, the exchange rate and other macroeconomic indicators. All these indicators are closely linked to the welfare of the Australian people and prosperity of the Australian economy. The importance of an accurate macroeconomic analysis is increased in the current condition of inflationary pressures, fiscal challenges, climate change, and world market instabilities.Read moreRead less
