Quantitative reconstructions of Australian climates since the last Interglacial. A crucial test of the models used to project future climate is how well they reproduce past climates. The project will reconstruct Australian regional climates, from vegetation, fire and runoff records, and use these for climate-model evaluation - helping to provide a more solid basis for management of Australian resources in the future.
Climate and health benefits of restoring tropical peat swamp forests. This project aims to investigate the climate and health benefits of restoring the tropical peat swamp forests. The project will integrate novel, field-based paleo-reconstruction of the historical conditions, satellite observations of temperature and rainfall, and high-resolution modelling of the regional climate processes under different restoration scenarios. It will use this information to determine how restoration activitie ....Climate and health benefits of restoring tropical peat swamp forests. This project aims to investigate the climate and health benefits of restoring the tropical peat swamp forests. The project will integrate novel, field-based paleo-reconstruction of the historical conditions, satellite observations of temperature and rainfall, and high-resolution modelling of the regional climate processes under different restoration scenarios. It will use this information to determine how restoration activities affect the regional climate, how changes in climate affect peatland fires and regional smoke haze, and how changes to regional climate and smoke haze affect human respiratory health and heat stress.Read moreRead less
Quantifying and mitigating changes in Australia’s rainfall belts. This project aims to understand how past climate changes affected Australia’s rainfall belts, and to reverse recent changes in rainfall belts. Australia’s climate belts are moving, but it is unclear if the effects on tropical and temperate rainfall will be permanent. This project will use past climate records and palaeoclimate databases to assess how natural and human-induced changes during the past millennium affected Australia’s ....Quantifying and mitigating changes in Australia’s rainfall belts. This project aims to understand how past climate changes affected Australia’s rainfall belts, and to reverse recent changes in rainfall belts. Australia’s climate belts are moving, but it is unclear if the effects on tropical and temperate rainfall will be permanent. This project will use past climate records and palaeoclimate databases to assess how natural and human-induced changes during the past millennium affected Australia’s rainfall zones, and specialised climate model simulations to determine whether greenhouse gas reduction could mitigate future rainfall changes. The outcomes are expected to inform policy and mitigation strategies to secure Australia’s precious water resources.Read moreRead less

Summary
An Australian fluid-inclusion facility for climate-change science. Understanding past temperature and rainfall changes is essential for improving climate projections. The proposed facility will generate new palaeotemperature and palaeorainfall information from cave deposits, leading to a better understanding of natural climate variability and change.
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.

This project will generate the fundamental science outputs required to extend historical records of change and understand the complex linkages between Australian and global atmospheric, terrestrial and marine processes in the climate system, thereby assisting in: (i) identifying the mechanisms of past and future climate variability; (ii) developing and validating methodologies for improved climate reconstruction and robust chronological frameworks; (iii) predicting the response of Australian ecosystems to future climate change; and (iv) communicating the research outputs to the general public and state, national and international decision makers, helping scientific understanding and aiding resource management.Read moreRead less
The evolution of the El Niño-Southern Oscillation in southeast Australia. El Niño events starve southeast Australia of rainfall, resulting in droughts and wildfires. El Niño activity is projected to amplify as global temperatures rise, heralding a serious threat to Australia's water security and the incidence and magnitude of wildfires. The key to understanding the potential effects of future changes in El Niño activity lies in the past. El Niño activity has varied substantially over the last 12 ....The evolution of the El Niño-Southern Oscillation in southeast Australia.

The key to understanding the potential effects of future changes in El Niño activity lies in the past. El Niño activity has varied substantially over the last 12,000 years. This project will reconstruct the response of southeast Australian climate, vegetation and fire activity to changes in El Niño activity over this period using lake sediments located in El Niño sensitive locations in Tasmania.Read moreRead less

This project aims to address fundamental questions about the causes of Australia’s rainfall variability, providing crucial information about how changing climates affect the water cycle. Bringing together earth system data from ground-based and satellite observations, palaeoclimate reconstructions and climate model simulations, it plans to analyse the processes that cause change in Australia’s rainfall. The project aims to integrate these datasets using the novel analysis of water isotopes, an important diagnostic of the water cycle. This approach is expected to help evaluate how Australia’s rainfall responds to natural and anthropogenic drivers and identify the processes behind recently observed rainfall extremes.Read moreRead less
Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings.

This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Australia, the project will extend hydroclimatic records by several centuries, to identify the frequency and extent of extreme droughts across the continent. Outcomes are expected to provide appropriate context for evaluating and adapting to climate change, allowing climate modellers, agricultural producers and other industries to improve forecasts of likely change for risk management.Read moreRead less
