Summary
Sea level change and climate sensitivity. This project will aim to improve understanding of climate and sea-level change on timescales relevant to longer-term planning, by characterising the relationship between past sea-level/ice-volume change and other key climate factors such as temperature and greenhouse gases, and by quantifying how rapidly sea level may adjust to climate change.
Understanding total long-term sea-level consequences. This project addresses the urgency in long-term infrastructure planning to understand the long-term "equilibrium" sea-level-change consequences from today’s exceptionally rapid climate change. Understanding this requires detailed sea-level reconstructions back to warm periods with similar CO2 levels to today (~3.5 million years ago), but these remain insufficiently defined. To advance, the project will deliver a next-generation, multi-million ....Understanding total long-term sea-level consequences. This project addresses the urgency in long-term infrastructure planning to understand the long-term "equilibrium" sea-level-change consequences from today’s exceptionally rapid climate change. Understanding this requires detailed sea-level reconstructions back to warm periods with similar CO2 levels to today (~3.5 million years ago), but these remain insufficiently defined. To advance, the project will deliver a next-generation, multi-million-year sea-level reconstruction that includes dynamically evolving (time-dependent) interactions between critical climate factors. This will then be applied with other palaeoclimate data to reconstruct equilibrium relationships between sea level, temperature, and CO2 at currently unattainable precision. 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

This project aims to bring the next generation of ocean-sea ice models to Australia and configure the models for our local priorities. The ultimate goal is to create a new coupled ocean-sea ice model for Australia that includes surface waves and biogeochemistry. The model will be optimised and evaluated on Australian facilities, and released for community use. These developments underpin future ocean state forecasts, sea ice forecasts, wave forecasts, decadal climate prediction and climate process studies. The project will benefit search and rescue, Defence and shipping operations, and will enhance future climate projections.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.
How topography brakes the Antarctic Circumpolar Current. This project aims to observe and simulate the mechanisms that slow the Antarctic Circumpolar Current. The Southern Ocean winds have increased over the last two decades while the transport of the world’s largest current remains steady or slightly decreasing. A possible explanation is negative feedback mechanisms between the winds and transport of the Antarctic Circumpolar Current. This project will observe how eddies carry momentum from the ....How topography brakes the Antarctic Circumpolar Current. This project aims to observe and simulate the mechanisms that slow the Antarctic Circumpolar Current. The Southern Ocean winds have increased over the last two decades while the transport of the world’s largest current remains steady or slightly decreasing. A possible explanation is negative feedback mechanisms between the winds and transport of the Antarctic Circumpolar Current. This project will observe how eddies carry momentum from the wind down to the sea floor and accelerate the deep currents that drag against the rough bottom to put the brakes on this current. Since this current affects Australian rainfall patterns and agricultural output, findings could inform public policy.Read moreRead less
Australia's variable rainfall - how dry or wet can it really get? Australia’s rainfall is extremely variable, which means existing weather records are too short to calculate the true risk posed by droughts and floods. This project aims to quantify how naturally variable the rainfall coming from the Indo-Pacific mid-latitudes is, allowing recent rainfall extremes and future projections to be assessed in a long-term context. This project expects to produce new estimates of atmospheric moisture bud ....Australia's variable rainfall - how dry or wet can it really get? Australia’s rainfall is extremely variable, which means existing weather records are too short to calculate the true risk posed by droughts and floods. This project aims to quantify how naturally variable the rainfall coming from the Indo-Pacific mid-latitudes is, allowing recent rainfall extremes and future projections to be assessed in a long-term context. This project expects to produce new estimates of atmospheric moisture budgets between Australia and Antarctica based on a novel, 1000-year length reconstruction of moisture-bearing southern Indian Ocean storms. This new information is critically needed by water managers so that they can properly calculate (and ultimately prepare for) the worst of Australia’s rainfall-related risks.Read moreRead less
Equator to Pole: Reconstructing tropical and Antarctic climate variability over the last millennium and their impacts on southern Australian rainfall. Water resource management is one of the greatest challenges facing sustainable agriculture and urban populations across southern Australia.

Water resource management is one of the greatest challenges facing sustainable agriculture and urban populations across southern Australia. Key players driving catastrophic droughts in southern Australia are the tropical Indian Ocean Dipole and polar Southern Annual Mode climate systems, which affect moisture availability and transport pathways. This collaborative research project draws together a uniquely-skilled research team to develop targeted coral, ice and cave reconstructions of these climate systems and their impacts on Australian rainfall through the last millennium. This fundamental new knowledge of the drivers of Australian rainfall variability will aid improved predictability of future changes in our valuable water resources. Read moreRead less
Climate and natural hazards in Australasia: a comprehensive impact analysis of prehistoric droughts, great earthquakes, and the Toba super-eruption. Climate change, great earthquakes, and volcanic disasters pose untold risks for environmental, economic, and social harm in rapidly developing Australasia. This project's ground-breaking natural hazard risk analysis will showcase Australasia's research strengths and provide fundamental knowledge for visionary leadership in sustainable development.
Dynamics of the Southern Ocean. The Southern Ocean is critically important to future global climate: it controls the natural global carbon cycle and the distribution of heat and nutrients around the ocean. This project will investigate key uncertainties in the Southern Ocean's response to climate change, and thereby improve our capacity to predict future climate.
