Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aim ....Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aims to apply novel observational methods, complimented by numerical modelling, to quantify the drivers of recent change. This project expects to transform our ability to predict how ocean temperature and sea level will change in the future.Read moreRead less
Evaluating the weather in climate models - the relationship of dynamics and rainfall over Australia in current and future climates. Climate change will be experienced by society as a change in the day-to-day weather. This project will investigate the capabilities of modern climate models in simulating the weather with a particular focus on rainfall, and will provide guidance to the use of these models in projections of the future of Australia's climate.
Reconstructing pre-20th century rainfall, temperature and pressure for south-eastern Australia using palaeoclimate, documentary and early weather station data. South-eastern Australia is in the grip of a severe water crisis due to the worst drought in recorded history and increasing temperatures.

South-eastern Australia is in the grip of a severe water crisis due to the worst drought in recorded history and increasing temperatures. This landmark project brings together a team of Australia's leading climate scientists, water managers and historians with the common goal of reconstructing south-eastern Australia's climate history. The greatly extended record of annual rainfall and temperature variability will allow better planning for water storage and use, and improved testing of climate model simulations. Improving our understanding of the historical impacts of climate extremes on society will assist with planning for life in a hotter and drier future.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

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.

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

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
Quantifying the El Niño-Indian Ocean Dipole system using high-resolution coral palaeoclimate archives. The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown.

The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown. To address this issue, this project will provide the first major geochemical investigation of recently discovered ancient corals in Indonesia using state-of-the-art microanalytical techniques. Outcomes from these palaeoclimate records will advance our understanding of global climate change, rainfall variability related to the El Nino - Indian Ocean Dipole system, and Australian drought.Read moreRead less
