Towards a climate theory of tropical cyclone formation. In Earth's current climate, about 80 to 90 tropical cyclones form every year around the globe, but the reasons why cyclones form at this rate are unknown. This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence ....Towards a climate theory of tropical cyclone formation.

This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence in our predictions of tropical cyclone incidence in a future, changed climate.Read moreRead less
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.
Re-evaluating the role of tannins in Australian forest ecosystems. As atmospheric CO2 concentrations rise, eucalypts will respond by decreasing the amount of protein in the leaves and increasing the concentrations of toxins called tannins. Together this will have the effect of making the leaves harder for herbivores to eat and slower to break down on the forest floor. We have developed a new way of measuring these effects and will use it to show which eucalypt communities climate change will mo ....Re-evaluating the role of tannins in Australian forest ecosystems. As atmospheric CO2 concentrations rise, eucalypts will respond by decreasing the amount of protein in the leaves and increasing the concentrations of toxins called tannins. Together this will have the effect of making the leaves harder for herbivores to eat and slower to break down on the forest floor. We have developed a new way of measuring these effects and will use it to show which eucalypt communities climate change will most affect and so which forests will become less able to support fauna. Apart from contributing to the better management of Australian forests, this project also enhances the National Carbon Accounting System by measuring how tannins influence litter decomposition and explaining the link with leaf chemistry.Read moreRead less
Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water c ....Understanding leaf water isotope composition. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for paleoclimatologists and plant scientists to constrain global carbon cycles. Leaf water stable isotopes influence the isotope compositions of atmospheric oxygen, carbon dioxide and water vapour, and impart an evaporative signal on the isotope composition of plant organic material. These isotope signals have been used to constrain global carbon and water cycles and reconstruct past climates. This project aims to quantify variation in leaf water isotopes and develop mechanistic models for use by paleoclimatologists, plant scientists and to constrain global carbon cycles and develop accurate models of leaf water isotopes to reduce uncertainty in climate models.Read moreRead less
Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interac ....Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interactions, whilst models do not represent the functional characteristics and adaptions of eucalypts. This project will develop a strong evidence- and process-based understanding to quantify the functional behaviour of drought-adapted Eucalyptus species and leverage this insight to make future model projections.Read moreRead less
Understanding gender inequality in the post-pandemic future of work. This project examines the impact of the COVID-19 pandemic and economic crisis on the working futures of young women and men in three advanced market economies where the pandemic hit with varying degrees of severity. Young people have experienced the greatest upheaval of all workers, and the impact has been gendered. Recovery strategies will have lasting consequences for women’s and men’s working futures. The project will produc ....Understanding gender inequality in the post-pandemic future of work. This project examines the impact of the COVID-19 pandemic and economic crisis on the working futures of young women and men in three advanced market economies where the pandemic hit with varying degrees of severity. Young people have experienced the greatest upheaval of all workers, and the impact has been gendered. Recovery strategies will have lasting consequences for women’s and men’s working futures. The project will produce macro-level mapping of post-pandemic national work/care regimes, and micro-level survey data on young people’s experience of and attitudes to the future of work in Australia, the UK and Japan, to deliver insights on the gendered economic and social impact of the pandemic and inform a more inclusive global recovery.Read moreRead less

Working longer, staying healthy and keeping productive. This project aims to develop a policy suite to respond to an older workforce. By 2060, nearly half of Australians aged 64 or older will be employed. Failure to address their health problems could threaten Australia’s economy, tax base and provision of health and care services. This collaboration between national policy portfolios (employment, social services, workplace health and social equity) and expert scientists in work, health, social equality and policy process intends to reveal the diversity of older workers’ work-health dilemmas and effective ways for national policies to solve them. The policy suite will promote financial independence and meet social goals of equity and healthy ageing.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
