Global Climate Change, Carbon Dioxide (CO2), and the Evolution of Life in the Palaeozoic and Early Mesozoic. A critically important problem directly affecting our society is the effects of climate change on our life support systems and environment. But the impacts of climate change and increasing carbon dioxide (CO2) on the Earth's biosphere are not well understood, so much can be learnt from examining past events that have shaped its evolution.

A critically important problem directly affecting our society is the effects of climate change on our life support systems and environment. But the impacts of climate change and increasing carbon dioxide (CO2) on the Earth's biosphere are not well understood, so much can be learnt from examining past events that have shaped its evolution. Our research will provide important new insights into how life evolved and survived periods of major environmental upheaval in Earth history, especially its responses to large shifts in global temperatures and atmospheric CO2. These outcomes will provide valuable input to help project how future global warming and rapidly increasing carbon dioxide levels will likely impact our modern biosphere.Read moreRead less
Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critica ....Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critical threshold limits of CO2 emissions for sustainable calcification in both shallow tropical and deep-water marine ecosystems of the Southern Oceans.Read moreRead less
Water availability, evaporative demand and climate change. Water availability is the balance between supply (i.e., rainfall) and evaporative demand. Rainfall is well studied but evaporative demand is not. The scientifically useful measure of evaporative demand is the rate of evaporation of water from a metal pan - called pan evaporation. Worldwide measurements show decreasing pan evaporation rate over the last 30-50 years. This project will for the first time make a detailed study of that phenom ....Water availability, evaporative demand and climate change. Water availability is the balance between supply (i.e., rainfall) and evaporative demand. Rainfall is well studied but evaporative demand is not. The scientifically useful measure of evaporative demand is the rate of evaporation of water from a metal pan - called pan evaporation. Worldwide measurements show decreasing pan evaporation rate over the last 30-50 years. This project will for the first time make a detailed study of that phenomenon using a new purpose-built evaporation pan. This will result in better information and policy advice about changes in water availability with climate change.Read moreRead less

Molecular fossils, the evolution of Earth's early oceans and the origin of the oldest oil. Australia retains undiscovered oil reserves. We believe that a change in primitive marine life forms may have fundamentally changed the chemistry of the Earth's oceans and is responsible for the world's oldest oil reserves. While these reserves have been found, and successfully commercialised, overseas, similar reservoirs in Australia remain elusive. The project will develop and apply technologies based on ....Molecular fossils, the evolution of Earth's early oceans and the origin of the oldest oil. Australia retains undiscovered oil reserves. We believe that a change in primitive marine life forms may have fundamentally changed the chemistry of the Earth's oceans and is responsible for the world's oldest oil reserves. While these reserves have been found, and successfully commercialised, overseas, similar reservoirs in Australia remain elusive. The project will develop and apply technologies based on hydrocarbon biomarkers to help determine the oil-producing rock types of Precambrian sedimentary rocks. This allows us to estimate the oil's age and predict where petroleum reservoirs may be hidden. PhD students involved in the project will gain valuable knowledge about the link between changes in ecology and the carbon cycle.Read moreRead less
Lifetime Affordable Housing in Australia: Integrating environmental performance and affordability. Existing dwellings and the locations of suburban housing with respect to employment centres result in significant greenhouse gas emissions. Water and other environmental issues are also important in housing performance, and there is currently a perceived trade-off between these factors and the affordability of housing. For the first time in Australia, this study will focus on overcoming this appare ....Lifetime Affordable Housing in Australia: Integrating environmental performance and affordability. Existing dwellings and the locations of suburban housing with respect to employment centres result in significant greenhouse gas emissions. Water and other environmental issues are also important in housing performance, and there is currently a perceived trade-off between these factors and the affordability of housing. For the first time in Australia, this study will focus on overcoming this apparent policy dilemma. The research will inform future housing policy in strengthening Australia's economic and social fabric, while contributing towards Australia's National Research Priority 1 'Environmentally Sustainable Australia'. Outcomes will provide significant national economic, social, water use and greenhouse gas benefits for Australia.Read moreRead less

Carbon uptake and water use by plants: is there pre-stomatal control? Society relies on mathematical descriptions of climate change, weather forecasting, crop performance, and other processes in which the control of carbon uptake and water loss by plants forms a basic element. Scientists also use the same element in ascribing sources and sinks of carbon dioxide (CO2), describing vegetation, hydrological and ecological processes. A key physiological assumption in this element is now in doubt and ....Carbon uptake and water use by plants: is there pre-stomatal control? Society relies on mathematical descriptions of climate change, weather forecasting, crop performance, and other processes in which the control of carbon uptake and water loss by plants forms a basic element. Scientists also use the same element in ascribing sources and sinks of carbon dioxide (CO2), describing vegetation, hydrological and ecological processes. A key physiological assumption in this element is now in doubt and we will test it rigorously and if necessary provide a robust alternative. We will do this by developing a novel 'window' on intact leaf functioning that will reveal the concentration of water vapour and other gases inside leaves.Read moreRead less
