Summary
How will Pacific climate variability impact Australia in a warming world? Temperature variability in the Pacific Ocean is characterised by El Niño and La Niña (year-to-year variations) and the Interdecadal Pacific Oscillation (decadal variations). These phenomena are primary drivers of Australian temperature and rainfall. Leveraging new tools and methods, including Single Model Initial-Condition Large Ensembles, this project will investigate drivers of these phenomena, and their impacts on Austr ....How will Pacific climate variability impact Australia in a warming world? Temperature variability in the Pacific Ocean is characterised by El Niño and La Niña (year-to-year variations) and the Interdecadal Pacific Oscillation (decadal variations). These phenomena are primary drivers of Australian temperature and rainfall. Leveraging new tools and methods, including Single Model Initial-Condition Large Ensembles, this project will investigate drivers of these phenomena, and their impacts on Australia in a warming world. Outcomes include the quantification of how these climate phenomena modulate extreme weather events, and an understanding of how Indian and Atlantic Ocean warming affects the Pacific region. This will improve the prediction of extreme events, which is critical for preparation for their impacts.Read moreRead less
How do humans affect the nature and impacts of Australian heatwaves? This project aims to provide more accurate information on the human signal behind heatwaves and their impacts, by deriving a comprehensive approach of the detection and attribution of climate extremes. The project expects to generate robust estimates of the human signal behind high-impact events, and an innovative, versatile methodology that can be applied to any extreme event and its impacts. With the specific application to A ....How do humans affect the nature and impacts of Australian heatwaves? This project aims to provide more accurate information on the human signal behind heatwaves and their impacts, by deriving a comprehensive approach of the detection and attribution of climate extremes. The project expects to generate robust estimates of the human signal behind high-impact events, and an innovative, versatile methodology that can be applied to any extreme event and its impacts. With the specific application to Australian heatwave impacts on human health, key knowledge should support more targeted and accurate mitigation policies, minimising the strain on resources when future heatwaves occur. This should help in safeguarding future generations from deadly impacts of heatwaves.Read moreRead less

Summary
A comprehensive understanding of Australian heat waves: past, present and future. The frequency and duration of Australian heat waves is increasing. Existing theories include natural and human influences, however the relative roles of specific heat wave drivers are undefined. Using an ensemble of contemporary climate models, this project will determine the individual and combined roles of anthropogenic activities, natural forcings and internal variability that shape heat wave manifestation.

Existing theories include natural and human influences, however the relative roles of specific heat wave drivers are undefined. Using an ensemble of contemporary climate models, this project will determine the individual and combined roles of anthropogenic activities, natural forcings and internal variability that shape heat wave manifestation. Using the ability of models to simulate the appropriate mechanistic connections, plausible future projections of heat waves will be ascertained. This will be the first comprehensive analysis of changes in heat waves, providing essential resources for the adaptation, mitigation and preparedness towards future events.Read moreRead less
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

Summary
Future risks associated with ocean surface warming: impacts on climate, rainfall, carbon, and circulation. Climate change is already affecting Australia, with harsh drought, more intense bushfire seasons, increased monsoon rains, heatwaves, and warmer temperatures all a feature of the past few decades. Climate change is expected to accelerate in the future, warming the oceans at an increased rate. This will affect ocean circulation, carbon uptake and ocean-atmosphere modes, such as El Nino, with ....Future risks associated with ocean surface warming: impacts on climate, rainfall, carbon, and circulation. Climate change is already affecting Australia, with harsh drought, more intense bushfire seasons, increased monsoon rains, heatwaves, and warmer temperatures all a feature of the past few decades. Climate change is expected to accelerate in the future, warming the oceans at an increased rate. This will affect ocean circulation, carbon uptake and ocean-atmosphere modes, such as El Nino, with unknown intensity. This project will improve our preparedness for climate change by better quantifying the risks that ocean warming will transform Australia's climate, rainfall, and sea level; as well as the ocean's uptake of carbon and the global ocean circulation. This will benefit sectors including agriculture, water management, fisheries, and tourism.Read moreRead less
How will climate change affect sub-daily precipitation? This project will examine changes in sub-daily precipitation due to climate change. It will improve our understanding of the mechanisms that cause the changes at regional and local scales. Regional climate change projections produced will be freely available, and at a spatial and temporal scales suitable for impacts and adaptation studies.
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.

Summary
Dynamics, variability and change in Southern Ocean abyssal flows. Changes in the Southern Ocean abyssal circulation are linked with dramatic climate events, yet the associated dynamics are poorly understood. This project aims to determine the fundamental dynamic processes driving abyssal flows, and diagnose impacts of recent and projected climate change. The project also aims to bridge the large gap between conceptual and observational understanding of this vital limb of the ocean's overturning ....Dynamics, variability and change in Southern Ocean abyssal flows. Changes in the Southern Ocean abyssal circulation are linked with dramatic climate events, yet the associated dynamics are poorly understood. This project aims to determine the fundamental dynamic processes driving abyssal flows, and diagnose impacts of recent and projected climate change. The project also aims to bridge the large gap between conceptual and observational understanding of this vital limb of the ocean's overturning circulation. A significant innovation is that it will be the first study of the Southern Ocean abyss using realistic global-scale models capable of simulating all the key dynamic processes. Results will guide Southern Ocean observation programs, explain observed changes, and reduce uncertainties in climate projections.Read moreRead less
