What is extreme? Advancing insights into Australia’s variable rainfall. 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.

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
Are proposed land-based sinks for greenhouse gases resilient to climate change and natural variability? One strategy to reduce the scale of future climate change is to enhance the storage of carbon in vegetation and soils. Evidence suggests carbon stored in vegetation and soils is itself vulnerable to climate change, placing this stored carbon at risk; this project will assess this risk to advise on the reliability of using terrestrial systems as carbon sinks.
The changing relationship between the South Asian and Australian Monsoon in a warming world. The success or failure of the Australian and South Asian Monsoons can mean the difference between prosperity and severe hardship in the affected regions. This project will help to understand the causes of the monsoon variability, both natural and human-induced, and what the future might have in store.
Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water c ....Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water cycles and reconstruct past climates. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for use by paleoclimatologists, plant scientists and to constrain global carbon cycles and develop accurate models of leaf water isotopes to reduce uncertainty in climate models.Read moreRead less

Summary
Fast Disk Storage to Enable Big Data Science in Weather, Oceans and Climate. This project aims to expand Australia's capacity to do high-impact innovative climate, weather and oceanographic science. Science of this kind relies on massive data coupled to computationally highly intensive and complex analysis. Therefore, the project will purchase fast disk storage and install it at the National Computing Infrastructure. It is anticipated that the project will benefit the nation through better under ....Fast Disk Storage to Enable Big Data Science in Weather, Oceans and Climate. This project aims to expand Australia's capacity to do high-impact innovative climate, weather and oceanographic science. Science of this kind relies on massive data coupled to computationally highly intensive and complex analysis. Therefore, the project will purchase fast disk storage and install it at the National Computing Infrastructure. It is anticipated that the project will benefit the nation through better understanding of the climate system, including extremes; improvements in our capacity to make predictions; and through applications of the science to forecasting, the management of resources among other many other things.Read moreRead less

Eddy-resolving global ocean-sea ice modelling. This project aims to develop a world-class global ocean-sea ice model framework through a nationwide consortium. The resulting high resolution models are expected to provide the foundation for the next decade of Australian ocean-sea ice modelling capacity. This research should lead to improved ocean and sea ice prediction, ocean reanalyses, and climate projections, enhancing Australia's capacity to predict the ocean state on timescales of days to decades. This is expected to yield efficiencies in shipping, marine search and rescue and naval operations, and increase the accuracy of projected future changes in climate, sea level, ocean ecosystems and the cryosphere.Read moreRead less

Our capacity to assess the threat of climate change is undermined by an unacceptable level of uncertainty in the understanding and modelling of regional climates. The Centre will undertake world-class research targeting identified weaknesses in the physical, chemical and biological components of the climate system. We will engage and nurture graduate students and postdoctoral follows through a program of graduate training and mentoring to permanently transform our understanding of climate systems science particularly for the Australian region. The key outcome will be a dramatic enhancement in national capacity to understand and project the scale of future regional climate change.Read moreRead less

Summary
Tracking the response of the Australian climate to abrupt climate change. This project will use cutting-edge climate proxy analyses to reconstruct the response of the Australian climate system to global climate change over the last 2,000 years. The results will provide significant insight in to how future global climate change will impact on social, biological and physical systems in Australia.

The Great Barrier Reef (GBR) and how it will respond to future global climate changes is of fundamental importance to the nation. The project will address this challenge by investigating the submerged fossil coral reefs in the GBR. This will lead to a better understanding of the natural rates, range and forcing mechanisms that control global sea-level and climate variability (ie. paleo-ENSO), and geo-biological changes affecting the GBR over the last 20,000 years. This project will provide unique insights into the response of the GBR to past environmental stress and improve predictions about the vulnerability of GBR to future global climate changes.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.
