Hydrological changes in Australia and the South Pacific. This project plans to use stalagmites from the South–West Pacific to generate continuous rainfall records for the last 2000 years. Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in ....Hydrological changes in Australia and the South Pacific.

Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in the Pacific. This knowledge would increase our scientific understanding and enable better predictions of the recurrence of droughts and wet events in Australia.Read moreRead less
Integrating past ice sheet dynamics with palaeoclimate in the Weddell Sea sector to evaluate current and future change in Antarctica. This project will extend historical records of change and understand the complex linkages between Antarctic climate and ice sheet dynamics, thereby assisting in: (i) identifying the mechanisms of past and future ice sheet stability, and (ii) communicating the research outputs to the general public, helping scientific understanding.
Reconstructing changes in atmospheric circulation over the mid-latitudes of the Southern Hemisphere during the past 3000 years. The climate of the mid-latitudes of the southern hemisphere is of global significance and yet past changes have proved difficult to reconstruct due to the dearth of records. Working across the Southern Ocean region using tree rings, lake sediments and ice cores, the project will produce the first comprehensive reconstruction spanning the last 3000 years.

This project will generate the fundamental science outputs required to extend historical records of change and understand the complex linkages between Australian and global atmospheric, terrestrial and marine processes in the climate system, thereby assisting in: (i) identifying the mechanisms of past and future climate variability; (ii) developing and validating methodologies for improved climate reconstruction and robust chronological frameworks; (iii) predicting the response of Australian ecosystems to future climate change; and (iv) communicating the research outputs to the general public and state, national and international decision makers, helping scientific understanding and aiding resource management.Read moreRead less
Shaping a sunburnt country: fire, climate and the Australian landscape. Fire shapes Australia’s landscape, biodiversity and resources. This project aims to quantify the recent history of fire intensity and severity using several novel proxies in the fire-prone landscapes of south-eastern Australia. Calibration of these new proxies to recent wildfires will be used for a better characterisation of fire regimes. This research will be applied to sedimentary archives to investigate how fire regimes h ....Shaping a sunburnt country: fire, climate and the Australian landscape. Fire shapes Australia’s landscape, biodiversity and resources. This project aims to quantify the recent history of fire intensity and severity using several novel proxies in the fire-prone landscapes of south-eastern Australia. Calibration of these new proxies to recent wildfires will be used for a better characterisation of fire regimes. This research will be applied to sedimentary archives to investigate how fire regimes have evolved over the past 100 years. The outcomes will inform debates about the relationship between climatic variability and fire severity, and this will contribute to increase the preparedness of natural resource management to potential future climate and land-use scenarios.Read moreRead less
Understanding the drivers and impacts of long-term Antarctic ice sheet change. This project will extend historical records of change and develop an understanding of the complex linkages between the climate and Antarctic ice sheet dynamics. The results will thereby assist in identifying the mechanisms of the past and future ice sheet stability and be communicated to the general public by enhancing scientific understanding.
Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Austra ....Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Australian-led international project aims to determine the mechanisms and impacts of past interglacial Antarctic warming up to 2°C (relative to pre-industrial). Innovative techniques integrating horizontal ice cores and high resolution marine records will help identify polar tipping points and better plan for impacts in Australia.Read moreRead less
Mega spatial-scale, multi time-scale, ensemble assessment of climate change driven coastal change in South Eastern Australia. Climate change driven variations in mean sea level, storm surges, and waves will change the world's coastline. This project will, for the first time, develop innovative modelling methods to quantify the integrated impact of these climate drivers on coastal erosion along Australia's most developed and populated coastline: Sydney to Brisbane.
Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve ....Working with recovery: Future proofing our rivers against floods & droughts. It's happening! Rivers in coastal NSW are showing signs of recovery. 25 years of improved management has increased the structural and vegetative roughness of river channels. Getting the ‘fibre’ back into rivers has impacted most positively on flood hydrology, but less so on riparian vegetation quality. This project aims to understand how river recovery occurs, its impact on flood flows and test new techniques to improve vegetation quality. It will investigate where corridors of recovery are, where to prioritise rehabilitation and the cost:benefit of working with recovery. This will benefit public policy, improve flood and drought risk analysis, and change decision-making and rehabilitation practice - essentially future proofing our rivers.Read moreRead less
The last glaciation maximum climate conundrum and environmental responses of the Australian continent to altered climate states. This project will show how climate systems in south east Australia responded to large scale global change the last time this happened, which was about 21,000 years ago. By determining the climate response in Australia to this change, this project will help predict future response in rainfall and temperature to human-induced and natural climate change.
