Methods for establishing cumulative CO2 emission budgets for Australia. Limiting global warming requires curbing cumulative carbon emissions. However, we do not know how the quasi-linear relationship between cumulative carbon dioxide emissions and maximal warming is modulated by other climate-relevant gases (for example, sulphur oxide or Methane) nor have we quantified the relationship in sufficient detail for aligning national and international policy strategies.

However, we do not know how the quasi-linear relationship between cumulative carbon dioxide emissions and maximal warming is modulated by other climate-relevant gases (for example, sulphur oxide or Methane) nor have we quantified the relationship in sufficient detail for aligning national and international policy strategies. This project will develop new methods to establish global emission budgets for various climate targets and likelihoods. Options for Australia’s share will be quantified on the basis of effort-sharing proposals. This research is vital for Australian policy makers, the energy sector, and the public in order to plan for coming decades.Read moreRead less
Quantifying the flux of fugitive greenhouse gasses associated with coal seam gas and calibrating it to natural baseline and anthropogenic sources. Recent studies show that fugitive methane emissions associated with coal seam gas extraction pose a source of greenhouse gasses. In addition to the possible environmental impacts of methane emissions, quantifying the magnitude of emissions has potentially significant implications for future tax liabilities that could change the economics of the unconv ....Quantifying the flux of fugitive greenhouse gasses associated with coal seam gas and calibrating it to natural baseline and anthropogenic sources. Recent studies show that fugitive methane emissions associated with coal seam gas extraction pose a source of greenhouse gasses. In addition to the possible environmental impacts of methane emissions, quantifying the magnitude of emissions has potentially significant implications for future tax liabilities that could change the economics of the unconventional energy boom in Australia. The proposed research by an interdisciplinary team representing regulators, industry, and university researchers would establish a methodology for quantifying the flux of methane from gas fields. It would establish the range of natural baselines and determine the major sources of methane emissions using newly available highly sensitive instruments.Read moreRead less
Quantitative reconstructions of Australian climates since the last Interglacial. A crucial test of the models used to project future climate is how well they reproduce past climates. The project will reconstruct Australian regional climates, from vegetation, fire and runoff records, and use these for climate-model evaluation - helping to provide a more solid basis for management of Australian resources in the future.
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.
Representing low-frequency variability in hydro-climatic simulations for water resources planning and management in a changing climate. Simulating local hydro-climatology under likely climate change allows risk assessment of existing and future water infrastructure, along with the planning protocols needed to adapt to the changes ahead. This study aims to develop the tools needed to simulate local hydro-climatology, providing a basis for securing water for the generations to come.

Coral reefs, climate change and land-based pollution: past, present and future impacts on coral reef development. Major threats to the Great Barrier Reef (GBR) include climate change and deteriorating water quality. Environmental histories in the skeletons of reef building organisms will be used to determine how past, present and future environmental threats influence the growth and development of the GBR. Findings will help set national water quality targets.

By integrating a highly skilled team with new approaches and breakthrough technologies, the program anticipates discovery science, enhanced environmental forecasting and optimised decision-making to advance Australia’s position as an influential Antarctic nation.
Expected outcomes include better environmental management, unparalleled strategic decision-support for an effective Antarctic Treaty, and new minds to address Antarctica’s new challenges.
Anticipated benefits are the means to transform environmental forecasting and management in the Antarctic, for Australia, and to the advantage of global security.Read moreRead less
Past climate and environmental impacts on Great Barrier Reef paleoecology. This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death event ....Past climate and environmental impacts on Great Barrier Reef paleoecology. This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death events to establish which environmental stressors and paleoclimate variations are most critical for reef health. The outcomes will better constrain long term coral reef dynamics and provide significant benefits to those who manage reefs globally, since the Great Barrier Reef covers the full range of reef environments.Read moreRead less
The evolution of the El Niño-Southern Oscillation in southeast Australia. El Niño events starve southeast Australia of rainfall, resulting in droughts and wildfires. El Niño activity is projected to amplify as global temperatures rise, heralding a serious threat to Australia's water security and the incidence and magnitude of wildfires. The key to understanding the potential effects of future changes in El Niño activity lies in the past. El Niño activity has varied substantially over the last 12 ....The evolution of the El Niño-Southern Oscillation in southeast Australia.

El Niño activity is projected to amplify as global temperatures rise, heralding a serious threat to Australia's water security and the incidence and magnitude of wildfires. The key to understanding the potential effects of future changes in El Niño activity lies in the past. El Niño activity has varied substantially over the last 12,000 years. This project will reconstruct the response of southeast Australian climate, vegetation and fire activity to changes in El Niño activity over this period using lake sediments located in El Niño sensitive locations in Tasmania.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.
