Effects Of Climate Change On Resilience Of Fire Prone Eucalypt Communities, Harriet Marie Simpson-Southward

University of Wollongong Thesis Collection 2017+

Changes in climate and fire regimes, modified by topography, may lead to eucalypts evolving protective bark traits, reducing their likelihood of becoming fire-scarred. This may in turn influence eucalypt mortality rates and distribution patterns. For my thesis, I aimed to provide an insight into how climate, fire and topography may be related to current eucalypt species protective bark traits and fire scarring to infer how eucalypt species may evolve over time and be distributed in the future. I conducted field and laboratory studies in dry sclerophyll forests and a study on dry and wet sclerophyll forests using primary and secondary …

Comparative Effects Of Logging And Wildfire On Carbon And Fire Dynamics In Resprouting And Non-Resprouting Eucalypt Forests, Nicholas Wilson

University of Wollongong Thesis Collection 2017+

The tall (>30 m) eucalypt forests of south-eastern Australia are valued for their carbon storage and sequestration. However, they may also act as a carbon source given that they are prone to large wildfires and subject to commercial logging. Logging may reduce carbon stocks, but the relative losses compared to wildfire have not been quantified in many types of these forests. There is also growing evidence that logging may make carbon stocks in affected forests less resistant to fire and increase the risk of wildfire. These dynamics may also vary between eucalypt forest types. Carbon and fire dynamics in …

Resprouting Into The Future: Implications For Eucalyptus Forests In A Changing Climate, Eli Ryan Bendall

University of Wollongong Thesis Collection 2017+

Intensified disturbance regimes, associated with climate change, will place selective pressure on forests via the survival of individual trees. Elevated atmospheric [CO2] (eCO2) will complicate responses, potentially enhancing growth and post-disturbance recovery under future climates. My thesis aimed to build an understanding of the drivers of mortality and regeneration in forests, such as drought, fire and eCO2, combining descriptive field studies, a glasshouse experiment and a remote sensing study. I focused on the disturbance-prone Eucalyptus forests of southern Australia, comparing responses between forest types, e.g. wet versus dry. I asked whether increases in drought and fire increased mortality of both …

It Is Hot In The Sun: Antarctic Mosses Have High Temperature Optima For Photosynthesis Despite Cold Climate, Alicia V. Perera-Castro, Melinda J. Waterman, Johanna Turnbull, Michael B.

The terrestrial flora of Antarctica’s frozen continent is restricted to sparse ice-free areas and dominated by lichens and bryophytes. These plants frequently battle sub-zero temperatures, extreme winds and reduced water availability; all influencing their ability to survive and grow. Antarctic mosses, however, can have canopy temperatures well above air temperature. At midday, canopy temperatures can exceed 15°C, depending on moss turf water content. In this study, the optimum temperature of photosynthesis was determined for six Antarctic moss species: Bryum pseudotriquetrum, Ceratodon purpureus, Chorisodontium aciphyllum, Polytrichastrum alpinum, Sanionia uncinata, and Schistidium antarctici collected from King George Island (maritime Antarctica) and/or the …

Satellite retrievals of column-averaged dry-air mole fractions of carbon dioxide (CO2) and methane (CH4), denoted XCO2 and XCH4, respectively, have been used in recent years to obtain information on natural and anthropogenic sources and sinks and for other applications such as comparisons with climate models. Here we present new data sets based on merging several individual satellite data products in order to generate consistent long-term climate data records (CDRs) of these two Essential Climate Variables (ECVs). These ECV CDRs, which cover the time period 2003-2018, have been generated using an ensemble of data products from the satellite sensors SCIAMACHY/ENVISAT and …

The IPCC (Intergovernmental Panel on Climate Change) "Special Report on Global Warming of 1.5°C" presented the ambitious target of needing to achieve zero net emissions by 2050 in order to meet the goals of the Paris Agreement (IPCC, 2018). This report led some governments and jurisdictions to declare a climate emergency (Climate Emergency Declaration, 2019) and prompted the rise of movements of activism and civil disobedience such as the School Strike for the Climate and Extinction Rebellion. The reach of these civil actions extends beyond those directly involved, potentially increasing wider public awareness of climate change. Here, we examine trends …

Drought And Climate Change Were The Kindling, And Now The East Coast Is Ablaze, Ross A. Bradstock, Rachael H. Nolan

Faculty of Science, Medicine and Health - Papers: Part B

Last week saw an unprecedented outbreak of large, intense fires stretching from the mid-north coast of New South Wales into central Queensland. The most tragic losses are concentrated in northern NSW, where 970,000 hectares have been burned, three people have died, and at least 150 homes have been destroyed. A catastrophic fire warning for Tuesday has been issued for the Greater Sydney, Greater Hunter, Shoalhaven and Illawarra areas. It is the first time Sydney has received a catastrophic rating since the rating system was developed in 2009.

Changes in stratospheric ozone and climate over the past 40-plus years have altered the solar ultraviolet (UV) radiation conditions at the Earth's surface. Ozone depletion has also contributed to climate change across the Southern Hemisphere. These changes are interacting in complex ways to affect human health, food and water security, and ecosystem services. Many adverse effects of high UV exposure have been avoided thanks to the Montreal Protocol with its Amendments and Adjustments, which have effectively controlled the production and use of ozone-depleting substances. This international treaty has also played an important role in mitigating climate change. Climate change is …

Linkages Between Stratospheric Ozone, Uv Radiation And Climate Change And Their Implications For Terrestrial Ecosystems, Janet F. Bornman, Paul W. Barnes, T Matthew Robson, Sharon A. Robinson, Marcel A.K Jansen, Carlos L. Ballare, Stephan D. Flint

Faculty of Science, Medicine and Health - Papers: Part B

Exposure of plants and animals to ultraviolet-B radiation (UV-B; 280-315 nm) is modified by stratospheric ozone dynamics and climate change. Even though stabilisation and projected recovery of stratospheric ozone is expected to curtail future increases in UV-B radiation at the Earth's surface, on-going changes in climate are increasingly exposing plants and animals to novel combinations of UV-B radiation and other climate change factors (e.g., ultraviolet-A and visible radiation, water availability, temperature and elevated carbon dioxide). Climate change is also shifting vegetation cover, geographic ranges of species, and seasonal timing of development, which further modifies exposure to UV-B radiation. Since our …

Secondary Students' Ideas About Scientific Concepts Underlying Climate Change, Lorna E. Jarrett, George J. Takacs

Faculty of Engineering and Information Sciences - Papers: Part B

We present ideas about concepts underlying climate change, held by students in years 9 and 10. Misconceptions about climate change are common among students, and may be due to misconceptions about underlying concepts. To investigate this, we developed the Climate Change Concept Inventory (CCCI), and trialed it with 229 students; corroborating findings through focus group interviews. Our interview method and data analysis methods are described. Findings included overestimation of human contributions to atmospheric carbon inputs, ultra violet radiation in sunlight, and greenhouse gases in the atmosphere. Students were unaware that CO2 dissolves in water, and of the role of oceans …

Performance Simulation And Evaluation Of Net Zero Energy Buildings In An Australian Coastal Climate, Joel Anderson, Duane A. Robinson, Zhenjun Ma

Faculty of Engineering and Information Sciences - Papers: Part B

Net zero energy buildings (NZEB) are becoming more common, and as new energy saving designs and technologies become available, the ability to estimate overall energy use and understand the impact on operation of building appliances will become important. This paper outlines simulation results of performance improvements achieved by modifying various components (glazing, lighting, thermal comfort settings) of two tertiary education NZEBs and a typical modern commercial building. The DesignBuilder models' thermal performance and energy consumption were validated using real data from case study buildings. The work shows validating models of smaller, less conven-tional, buildings is more difficult than for larger …

Citizen Social Science For More Integrative And Effective Climate Action: A Science-Policy Perspective, Andrew Kythreotis, Chrystal Mantyka-Pringle, Theresa Mercer, Lorraine Whitmarsh, Adam Corner, Jouni Paavola, Christopher D. Chambers, Byron Miller, Noel Castree

Faculty of Social Sciences - Papers (Archive)

Governments are struggling to limit global temperatures below the 2°C Paris target with existing climate change policy approaches. This is because conventional climate policies have been predominantly (inter)nationally top-down, which limits citizen agency in driving policy change and influencing citizen behavior. Here we propose elevating Citizen Social Science (CSS) to a new level across governments as an advanced collaborative approach of accelerating climate action and policies that moves beyond conventional citizen science and participatory approaches. Moving beyond the traditional science-policy model of the democratization of science in enabling more inclusive climate policy change, we present examples of how CSS can …

The Interactive Effects Of Stratospheric Ozone Depletion, Uv Radiation, And Climate Change On Aquatic Ecosystems, Craig E. Williamson, Patrick Neale, Samuel Hylander, Kevin C. Rose, Felix L. Figueroa, Sharon A. Robinson, Donat -P Hader, Sten-Ake Wangberg, Robert Worrest

Faculty of Science, Medicine and Health - Papers: Part B

This assessment summarises the current state of knowledge on the interactive effects of ozone depletion and climate change on aquatic ecosystems, focusing on how these affect exposures to UV radiation in both inland and oceanic waters. The ways in which stratospheric ozone depletion is directly altering climate in the southern hemisphere and the consequent extensive effects on aquatic ecosystems are also addressed. The primary objective is to synthesise novel findings over the past four years in the context of the existing understanding of ecosystem response to UV radiation and the interactive effects of climate change. If it were not for …

Executive Summary: Thirty-four years ago, an unprecedented thinning of stratospheric ozone was reported over Antarctica.The risk of a consequent increase in exposure to solar UV-B radiation (UV-B; wavelengths 280-315 nm) raised concerns about potentially disastrous effects on human health and the Earth's environment. In response, the international community mobilised and worked together to understand the causes and find a solution to this dramatic change in the Earth's atmosphere. In 1985, the Vienna Convention for the Protection of the Ozone Layer was signed, which provided the framework for the Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987. …

Impact Of Climate Change And Human Activity On Soil Landscapes Over The Past 12,300 Years, Leo Rothacker, Anthony Dosseto, Alexander Francke, Allan Chivas, Nathalie Vigier, Anna M. Kotarba-Morley, Davide Menozzi

Faculty of Science, Medicine and Health - Papers: part A

Soils are key to ecosystems and human societies, and their critical importance requires a better understanding of how they evolve through time. However, identifying the role of natural climate change versus human activity (e.g. agriculture) on soil evolution is difficult. Here we show that for most of the past 12,300 years soil erosion and development were impacted differently by natural climate variability, as recorded by sediments deposited in Lake Dojran (Macedonia/Greece): short-lived ( < 1,000 years) climatic shifts had no effect on soil development but impacted soil erosion. This decoupling disappeared between 3,500 and 3,100 years ago, when the sedimentary record suggests an unprecedented erosion event associated with the development of agriculture in the region. Our results show unambiguously how differently soils evolved under natural climate variability (between 12,300 and 3,500 years ago) and later in response to intensifying human impact. The transition from natural to anthropogenic landscape started just before, or at, the onset of the Greek 'Dark Ages' (~3,200 cal yr BP). This could represent the earliest recorded sign of a negative feedback between civilization and environmental impact, where the development of agriculture impacted soil resources, which in turn resulted in a slowdown of civilization expansion.

A Meta-Ethnography To Synthesise Household Cultural Research For Climate Change Response, Lesley M. Head, Christopher R. Gibson, Nicholas J. Gill, Chontel A. Carr, Gordon R. Waitt

Faculty of Social Sciences - Papers (Archive)

Cultural change is critical to climate change responses, but the in-depth qualitative research that investigates culture is necessarily conducted at scales difficult to integrate with policy. A focus of climate change mitigation and adaptation is affluent developed world households. Adapting methods used elsewhere in social science, we report and assess a meta-ethnography of household sustainability research, scaling up findings from 12 studies encompassing 276 Australian households. Seven themes are dominant: family concerns are central to household practice; adaptiveness is contingent but more pervasive than often assumed; households make sense of climate change not through abstract arguments, but through physical resources …

Social Climate Profiles In Adolescent Sports: Associations With Enjoyment And Intention To Continue, Lauren Gardner, Christopher A. Magee, Stewart A. Vella

Faculty of Social Sciences - Papers (Archive)

This study explored whether adolescent sports participants' perceptions of the social climate fall into distinct profiles, and whether these profiles are related to enjoyment and intention to continue. A Latent Profile Analysis using 313 Australian sports participants (M_age = 13.03 years) revealed four distinct profiles: positive social climate (45.1%), diminished social climate (19.8%), positive coach relationship quality (19.8%), and positive friendship quality (15.3%). Individuals within the positive social climate and the positive coach relationship quality profiles reported relatively higher levels of enjoyment and intention to continue than individuals in the diminished social climate and the positive friendship quality …

Broaden Research On The Human Dimensions Of Climate Change, Noel Castree

Faculty of Social Sciences - Papers (Archive)

Human actions are causing global environmental changes that, in turn, have significant human impacts and demand human responses. The magnitude of change, impact and response will only increase in the decades to come. For too long science, technology, engineering and mathematics (STEM) subjects have dominated research into how people are altering the atmosphere, biosphere, cryosphere, hydrosphere and lithosphere. We now urgently need to understand, and seek to alter, human behaviour so that our planet remains a liveable one for all people.

Re-Thinking Climate Change Adaptation And Capacities At The Household Scale, Stephanie Toole, Natascha Klocker, Lesley M. Head

Faculty of Social Sciences - Papers (Archive)

The reality of anthropogenic climate change has rendered adaptive responses at all scales an imperative. Households are an increasing focus of attention, but more in the developing world than the developed world, because of the presumed lesser vulnerabilities and stronger adaptive capacities of the latter. Critiques of such presumptions, and the quantitative, macro-scale focus of much adaptation research are emergent. How relatively affluent households, as complex social assemblages, may adapt to climate change impacts encountered in their day-to-day functioning remains unclear. There is, however, a sizeable body of research on household environmental sustainability in the developed world. That research has …

Geographers And The Discourse Of An Earth Transformed: Influencing The Intellectual Weather Or Changing The Intellectual Climate?, Noel Castree

Faculty of Social Sciences - Papers (Archive)

This article considers how geographers might choose to respond to many geoscientists' claims that we are entering 'the age of humans'. These claims, expressed in the concepts of the Anthropocene, planetary boundaries and global tipping points, make epochal claims about Earth surface change that are also far-reaching claims upon Earth's current inhabitants. The scale and scope of their normative implications are extraordinarily grand. After describing the content and wider context for these claims, the history of some geographers' engagement with global change research is sketched and their current contributions described. Wider alterations in the modus operandi of global change scientists …

Reply To 'Strategies For Changing The Intellectual Climate' And 'Power In Climate Change Research', Noel Castree

Faculty of Social Sciences - Papers (Archive)

Although they challenge some of our claims, Myanna Lahsen and colleagues and Lauren Rickards agree with us that a new intellectual climate ought to prevail in the world of global-change science. We concur with Lahsen et al. that there are other (perhaps better) examples than those that we chose to illustrate the tendency of global change scientists to presume that a 'single, seamless concept of integrated knowledge' is realizable and desirable; Paul Palmer and Matthew Smith provide a recent case in Nature. We apologise if we misrepresented Barnes et al., and applaud the recent efforts of Barnes and Dove to …

Fire, Water And Everyday Life: Bushfire And Household Defence In A Changing Climate, Carrie Wilkinson, Christine Eriksen

Faculty of Social Sciences - Papers (Archive)

This paper examines how the availability or scarcity of water influenced the survival related decisions of households during the October 2013 State Mine Fire in the Blue Mountains, New South Wales, Australia. Narrative analysis of semi-structured interviews with 18 households impacted by the bushfire revealed that drought conditions in the months preceding the bushfire left many households dependent on non-reticulated water supplies vulnerable at the time the fire threat became apparent. Despite considerable preparations for water storage and usage during the fire, "weak links" in planning (e.g., top-ups, failure of pumps, generators and hoses) meant water was not accessible when …

This paper outlines the benefits of using the framework for an ecosystem approach to fisheries management (EAFM) for dealing with the inevitable yet unclear impacts of climate change and ocean acidification on coastal fisheries. With a focus on the Asia-Pacific region, it summarizes the projected biological and socio-economic effects of increased emissions of carbon dioxide (CO2) for coastal fisheries and illustrates how all the important dimensions of climate change and ocean acidification can be integrated into the steps involved in the EAFM planning process. The activities required to harness the full potential of an EAFM as an adaptation to climate …

Repositioning Urban Governments? Energy Efficiency And Australia's Changing Climate And Energy Governance Regimes, Pauline M. Mcguirk, Robyn Dowling, Harriet Bulkeley

Faculty of Social Sciences - Papers (Archive)

Urban local governments are important players in climate governance, and their roles are evolving. This review traces the changing nexus of Australia's climate policy, energy policy and energy efficiency imperatives and its repositioning of urban local governments. We characterise the ways urban local governments' capacities and capabilities are being mobilised in light of a changing multi-level political opportunity structure around energy efficiency. The shifts we observe not only extend local governments' role in implementing climate change responses but also engage them as partners in conceiving and operationalising new measures, suggesting new ground is being opened in the urban politics of …

We Need To Talk About How We Talk About Climate Change, Sharon Beder

Faculty of Law, Humanities and the Arts - Papers (Archive)

How we talk about climate change has a lot to do with how we feel about it, and what we’re willing to do to act on it. Recent research from the US found that the terms “global warming” and “climate change” evoke different reactions: global warming is perceived as far more threatening.

While there is no similar research in Australia, over the past 25 years we’ve seen debate shift from the greenhouse effect to climate change to climate variability — with a corresponding decrease in action to reduce greenhouse gas emissions.

Global warming, the US research found, is more likely …

Distributed Leadership: Building Capacity For Interdisciplinary Climate Change Teaching At Four Universities, Aidan Davison, Paul Brown, Emma Pharo, Kristin Warr, Helen Mcgregor, Sarah Terkes, Davina Boyd, Pamela Abuodha

Faculty of Science, Medicine and Health - Papers: part A

Purpose - Interdisciplinary approaches to climate change teaching are well justified and arise from the complexity of climate change challenges and the integrated problem-solving responses they demand. These approaches require academic teachers to collaborate across disciplines. Yet, the fragmentation typical of universities impedes collaborative teaching practice. This paper aims to report on the outcomes of a distributed leadership project in four Australian universities aimed at enhancing interdisciplinary climate change teaching. Design/methodology/approach - Communities of teaching practice were established at four Australian universities with participants drawn from a wide range of disciplines. The establishment and operation of these communities relied on …

A Combined Experimental And Simulation Method For Appraising The Energy Performance Of Green Roofs In Ningbo's Chinese Climate, Georgios Kokogiannakis, Jo Darkwa, Kate Yuan

Faculty of Engineering and Information Sciences - Papers: Part A

A passive means of lowering the energy demand of buildings is the application of green roofs. The complexity between heat and moisture exchanges in green roof layers and the large variations of green roof types make the need for experimental or simulation assessments necessary for quantifying the energy benefits from green roofs. The current treatment of green roofs in simulation programs is either over-simplistic, for example by ignoring heat and moisture exchanges such as evapotranspiration, or the more advanced models have limitations and require inputs that are rarely available in practice. In this paper a combination of experimental and modelling …

Integrated Dehumidification And Downdraft Evaporative Cooling System For A Hot-Humid Climate, Sriraj Gokarakonda, Georgios Kokogiannakis

Faculty of Engineering and Information Sciences - Papers: Part A

Unlike in hot-dry climates, in hot-humid climates evaporative cooling techniques are not readily suitable for space cooling. In order to effectively use evaporative cooling in hot-humid climates, dehumidification of ambient air is necessary before it passes over an evaporative medium for cooling. The present study explores the combined process of dehumidification and evaporation and its effect on thermal comfort in a typical small residential building located in a hot humid climate. A novel system has been investigated with the combination of an Earth Tube Ventilation (ETV) (for pre-cooling of air), a rotary wheel desiccant dehumidifier (for dehumidification) along with a …
