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.
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
Eddy-resolving global ocean-sea ice modelling. 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.

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
ARC Centres of Excellence for Climate System Science. 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.

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
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.
Remote forcing of Pacific Ocean variability and impacts on global climate. Variability in the Pacific Ocean has a profound impact on global climate. Recent unprecedented decadal variability in the Pacific has been linked to global temperature trends and extremes, yet little is known about what drives this variability or its impact on regional climate. This project will combine observations, advanced coupled climate models and ocean-atmosphere dynamical theory to quantify remote drivers of Pacifi ....Remote forcing of Pacific Ocean variability and impacts on global climate. Variability in the Pacific Ocean has a profound impact on global climate. Recent unprecedented decadal variability in the Pacific has been linked to global temperature trends and extremes, yet little is known about what drives this variability or its impact on regional climate. This project will combine observations, advanced coupled climate models and ocean-atmosphere dynamical theory to quantify remote drivers of Pacific Ocean variability on interannual-decadal time-scales. This project aims to enhance our understanding of the modes of variability operating in this region and their impact on global and Australian climate. This will have significant benefits for the many sectors of society reliant on interseasonal-decadal climate prediction.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.
