Healthcare contributes to environmental harm. Trainee-led Research and Audit in Anaesthesia for Sustainable Healthcare (TRA2SH) is an Australasian network focused on sustainable anaesthesia practice. TRA2SH hypothesised that trainee-led audits alongside education presented on a scheduled national day, called Operation Clean Up, can improve engagement with sustainability initiatives. This paper aims to describe the first two years of Operation Clean Up in terms of goals, achievements and data collected so far. Environmental themes for Operation Clean Up were chosen based on available evidence (life cycle analyses and observational studies). The first Operation Clean Up (OCU 2020) focused on reducing the unnecessary use of single-use disposable absorbent pads (known as 'blueys' in Australia, 'greenies' in New Zealand). OCU 2021 included: refuse desflurane, reduce bluey use, reuse drug trays, and recycle paper and cardboard. TRA2SH provided an information pack to trainees who presented educational material to their department and fed back procurement figures to quantify each item. Descriptive statistics were used to analyse de-identified pooled data submitted to a centralised database. Eight departments submitted data for OCU 2020 and six provided follow-up data. Bluey use was reduced from a median of 37 to 34 blueys per ten surgical encounters. Fifteen departments submitted pre-campaign data for OCU 2021 with follow-up data to be collected during OCU 2022. Baseline data showed a median bluey use of 31 per ten surgical encounters. Volatile-related emissions were calculated; desflurane's proportion was 70% of these emissions yet was 11% of volatile procurement. Two participating departments removed desflurane from their formulary following OCU 2021. Operation Clean Up is a practical model for implementing sustainability initiatives using trainees as eco-leaders. [ABSTRACT FROM AUTHOR]

The three challenges with the greatest bearing on Australia's security and prosperity each came to a head in 2020, viz. climate change; a novel coronavirus pandemic; and China. The world has become poorer, more dangerous and more disorderly. As we emerge from this crisis year, Australia's ability to project itself globally will start with its strength and vitality at home. Its favourable geography gives it the potential to become a leader in renewables. Given our geopolitical challenges, this is a strategic imperative. Yet, for now, the gap between reality and expectations has never been greater. [ABSTRACT FROM AUTHOR]

Since the beginning of the 19th century, the natural environment of the planet has been placed under the dire threat of climate change. This has been caused by greenhouse gas (GHG) emissions from the burning of fossil fuels. GHG emissions threaten to alter the planet's ecosystems disastrously and permanently. Statistics reveal that Australian individuals are among the highest GHG emitters on the planet, and that the transport sector contributes nearly one-fifth of the nation's GHG emissions. It is suggested that significant reductions in Australian GHG emissions are urgently required, and it is considered that those reductions might be helped by a transition to electric vehicles (EVs) in the transport sector. This paper looks at the consumption of motor vehicle fuels in Australia's transport sector and suggests how a reduction in GHG emissions might be achieved. It suggests that the electrification of Australian motor vehicles could eliminate up to 20 per cent of existing Australian GHG emissions. The paper presents further findings from a case study that was conducted on a Mitsubishi Outlander Plug-in Electric Hybrid Vehicle (PHEV) in remote Western Australia from 2016-17. That study is updated and extended in this paper to October 2021. The paper uses published statistical data from the Organisation for Economic Co-operation and Development (OECD) and Australian government agencies to support its findings, conclusions and suggestions for further research. It looks at the rate of transition to electric vehicles and concludes that, while the transport sector's growing contribution to Australia's overall GHG emissions could be significantly reduced by the transition to electric vehicles, there is some way to go. The paper suggests that there are significant economic factors inhibiting the adoption of electric vehicles in Australia. However, rising fuel prices could encourage the transition away from vehicles powered by environmentally damaging internal combustion engines towards electric vehicles in Australia.

Heat stress, resulting from elevated heat and absolute humidity associated with climate change, will increasingly occur in the tropics and parts of the mid-latitudes and could threaten the liveability and viability of many regions. Concomitant with predictions of increased heat stress in northern Australia, the Australian Government seeks to boost the population in northern Australia substantially. This paper assesses the heat stress-related wet-bulb temperatures the largest northern centres could experience under Representative Concentration Pathways 4.5 and 8.5 by 2080. The paper finds that substantial population growth could place significant future urban populations at risk from heat stress-related health issues. [ABSTRACT FROM AUTHOR]

Background: The climate crisis is a significant risk to the health and wellbeing of children, young people, and future generations. While there are calls for children and young people's engagement in climate decision making, current power structures limit their participation. This paper aimed to understand children's perspectives about the impact of the climate crisis on their futures, their ability to influence climate decisions, and strategies and mechanisms to facilitate their greater engagement in decisions made about the climate crisis. Methods: Online in-depth interviews were conducted with n = 28 children (aged 12–16 years) across Australia. Photo elicitation techniques were used to prompt discussion about how the climate crisis impacted their futures, their ability to influence climate decisions, and strategies and mechanisms to engage them in climate decision making. A reflexive approach to thematic analysis was used to construct three themes from data. Images were analysed for ascribed meanings. Results: First, participants stated that they and future generations will inherit the climate crisis from older generations, specifically decision makers. Second, they described a need to address a range of age-related barriers that limit children and young people's engagement in climate decision making, including perceptions about their capabilities. Finally, they discussed strategies and mechanisms to embed children and young people's perspectives within climate decision making, including at civic and political levels. Conclusions: Children and young people have the right to be involved in decisions made about the climate crisis which significantly impact their futures, including their health and wellbeing. They argue for structural changes to embed their views in climate decision making, and describe a range of engagement strategies and mechanisms to structure their perspectives and knowledge with decision making processes. Furthermore, genuine involvement of children and young people in climate discussions must avoid youthwashing and tokenistic participation. The public health community can help address barriers to youth participation in climate action and should actively engage and collaborate with children and young people to facilitate their political and democratic influence over the climate crisis. This involves making room and creating an accessible seat at the decision making table to ensure their perspectives are embedded in climate decisions. [ABSTRACT FROM AUTHOR]

Nurses, the largest healthcare workforce, are well placed to provide leadership in initiatives that promote planetary health. Yet, few practical examples of nurse leadership in the health sector's response to climate change are evident in the scholarly literature. The aim of this discussion paper is to profile Australian nurses who are leading initiatives designed to champion planetary health and promote sustainable practice. The paper presents a series of case studies derived from interviews conducted in October and November 2023. The nurses' experiences and insights, along with the challenges they have encountered, are presented as evidence of Kouzes and Posner's five practices of exemplary leadership. The case studies demonstrate that appointment of more nurses with climate and sustainability expertise will accelerate the implementation of responsive strategies that target waste management, emissions reduction and climate resilience across healthcare organisations.

Simple Summary: Invasive alien species, such as Carpomya vesuviana Costa (Diptera: Tephritidae), threaten global biodiversity, agriculture, and public health. This study used advanced modelling techniques to predict the potential distribution of C. vesuviana and understand its environmental impacts. The findings suggest that climate change is driving the geographic expansion of C. vesuviana, primarily in Asia, Africa, and Australia. The species is projected to shift poleward by the 2090s, as the species will have shifted to the polar regions under the influence of climate change. Effective management strategies are crucial to mitigate the environmental and health impacts of its expansion. Invasive alien species (IAS) significantly affect global native biodiversity, agriculture, industry, and human health. Carpomya vesuviana Costa, 1854 (Diptera: Tephritidae), a significant global IAS, affects various date species, leading to substantial economic losses and adverse effects on human health and the environment. This study employed biomod2 ensemble models, multivariate environmental similarity surface and most dissimilar variable analyses, and ecological niche dynamics based on environmental and species data to predict the potential distribution of C. vesuviana and explore the environmental variables affecting observed patterns and impacts. Compared to native ranges, ecological niche shifts at invaded sites increased the invasion risk of C. vesuviana globally. The potential geographical distribution was primarily in Asia, Africa, and Australia, with a gradual increase in suitability with time and radiation levels. The potential geographic distribution centre of C. vesuviana is likely to shift poleward between the present and the 2090s. We also show that precipitation is a key factor influencing the likely future distribution of this species. In conclusion, climate change has facilitated the expansion of the geographic range and ecological niche of C. vesuviana, requiring effective transnational management strategies to mitigate its impacts on the natural environment and public health during the Anthropocene. This study aims to assess the potential threat of C. vesuviana to date palms globally through quantitative analytical methods. By modelling and analysing its potential geographic distribution, ecological niche, and environmental similarities, this paper predicts the pest's dispersal potential and possible transfer trends in geographic centres of mass in order to provide prevention and control strategies for the global date palm industry.

Increasing the adoption of energy-efficiency measures (EEM) by households is one of the practical strategies to increase energy efficiency and reduce greenhouse gas emissions. For the 3.24 million low-income households in Australia, partly due to their potentially disproportionately large waste of usable energy, there is a gap between the potential for energy efficiency through existing EEM and the actual energy-efficiency level. Many measures increase energy efficiency in buildings; however, barriers persist for such households to adopt these measures, of which limited research has yet to be conducted. In response, this study examines the relationships involved by a questionnaire survey of 212 low-income households in Australia, showing that financial barriers have the greatest influence followed by split incentive barriers, with the provision of information having no significant role to play. This paper contributes to filling the gap of limited energy-efficiency research involving low-income households, revealing the effect of energy-efficiency barriers on their adoption of EEM.

This paper presents a method to analyze and improve the set of equations constituting a rainfall‐runoff model structure based on a combination of a data assimilation algorithm and polynomial updates to the state equations. The method, which we have called "Data Assimilation Informed model Structure Improvement" (DAISI) is generic, modular, and demonstrated with an application to the GR2M model and 201 catchments in South‐East Australia. Our results show that the updated model generated with DAISI generally performed better for all metrics considered included Kling‐Gupta Efficiency, NSE on log transform flow and flow duration curve bias. In addition, the elasticity of modeled runoff to rainfall is higher in the updated model, which suggests that the structural changes could have a significant impact on climate change simulations. Finally, the DAISI diagnostic identified a reduced number of update configurations in the GR2M structure with distinct regional patterns in three sub‐regions of the modeling domain (Western Victoria, central region, and Northern New South Wales). These configurations correspond to specific polynomials of the state variables that could be used to improve equations in a revised model. Several potential improvements of DAISI are proposed including the use of additional observed variables such as actual evapotranspiration to better constrain internal model fluxes. Plain Language Summary: This paper presents a data‐driven method to improve rainfall‐runoff models used to generate future water resources scenario in climate change studies. The method, which we have called "Data Assimilation Informed model Structure Improvement" (DAISI) is generic, modular, and demonstrated with an application to monthly streamflow simulations over a large data set of catchments in South‐East Australia. Our results show that DAISI improves model performance for a wide range of metrics and increases the sensitivity of the model to climate inputs, which is critical in climate change scenarios. Finally, the improvements identified by DAISI take a simple mathematical form with distinct regional patterns in three sub‐regions of the study domain (Western Victoria, central region, and Northern New South Wales). Several improvements of DAISI are discussed including the inclusion of additional observed variables such as evapotranspiration to better constrain model simulations. Key Points: Data Assimilation Informed model Structure Improvement method diagnoses hydrological model structures by combining data assimilation with a polynomial update of state equationsThe method was applied to the GR2M rainfall‐runoff model with significantly improved streamflow simulations in 201 Australian catchmentsThe method identified updates to state equations with marked regional characteristics that could guide future improvement of GR2M [ABSTRACT FROM AUTHOR]

The overall condition of biodiversity in many parts of Australia is poor and declining, despite the establishment of national parks and other reserves, and the adoption of conservation activities on private land. The impacts of climate change add further challenges to sustaining biodiversity. In response to these issues, in December 2009, the State Government of Victoria released a major policy statement that aimed to provide the framework and directions to secure the health of Victoria's biodiversity and associated land and water resources over the next 50 years. Given Victoria's reputation for environmental policy reform and innovation, the question arises as to whether the Victorian approach will provide a model for other Australian jurisdictions to adopt or adapt. Drawing on insights from environmental policy, discourse theory, and ecological theory, this article provides a critique of Victoria's approach, focusing on the way in which biodiversity is conceptualised and governed.

Heavy rainfall and precipitation play a massive role in shaping the socio-agricultural landscape of a country. Being one of the key indicators of climate change, natural disasters, and of the general topology of a region, rainfall prediction is a gift of estimation that can be used for multiple beneficial causes. Machine learning has an impressive repertoire in aiding prediction and estimation of rainfall. This paper aims to find the effect of ensemble learning, a subset of machine learning, on a rainfall prediction dataset, to increase the predictability of the models used. The classification models used in this paper were tested once individually, and then with applied ensemble techniques like bagging and boosting, on a rainfall dataset based in Australia. The objective of this paper is to demonstrate a reduction in bias and variance via ensemble learning techniques while also analyzing the increase or decrease in the aforementioned metrics. The study shows an overall reduction in bias by an average of 6% using boosting, and an average reduction in variance by 13.6%. Model performance was observed to become more generalized by lowering the false negative rate by an average of more than 20%. The techniques explored in this paper can be further utilized to improve model performance even further via hyper-parameter tuning. [ABSTRACT FROM AUTHOR]

Purpose: This paper explores the economic and social effects of human capital investment in the 20th century. As well as drawing on census data and statistical yearbooks in Australia and Aoteoroa/New Zealand, the paper develops its argument by an intersection of scholarly work in sociology, economics and the history of education to consider the effects of increased human capital investment on economic growth but also on the experiences of childhood, work discipline and the present climate crisis. Design/methodology/approach: This paper considers the implications of what economic historian Claudia Goldin has described as the "human capital century" for the history of school and university education. By reconsidering education in the settler colonies, especially Australia and Aoteoroa/New Zealand, as "stimulus", this helps explain key aspects of contemporary human capital investment, which the paper argues should be understood as constituted by children's and young people's free labour at school, university and across the economy. Findings: This research argues that children's and young people's free labour, performed in educational institutions, constitutes a large portion of Australia and Aoteoroa/New Zealand's national investment in human capital. At key points, this investment has acted as an economic stimulus, promoting surges of profitability. The effects were not confined to young people. Systematised, educational expansion also became the foundation of environmental degradation, labour market exploitation and a relentless increase in service-sector productivity that is worn on professional bodies. Productivity increases have been associated with reduced professional autonomy as a managerial class coerced professionals into working harder, though often under the guise of working "smarter" – a fiction that encouraged or coerced even greater personal investment in collective human capital. This investment of personal time, effort and selfhood by children and the professionals they grew into can thus be seen, in Marxian terms, as a crucial vector of capitalist exploitation in the 20th century. Practical implications: The paper concludes by suggesting that a reduction of managerial influence in educational settings would improve learner and professional autonomy with improved labour and environmental conditions. Originality/value: The paper makes a unique contribution to the history of education by exploring education as stimulus as a key component of education's role in 20th and 21st century capitalism. It interrogates exploitative aspects of human capital investment, especially in the midst of environmental catastrophe and the recent COVID crisis. [ABSTRACT FROM AUTHOR]

Climate change and associated processes can increase the occurrence of some natural hazards and threaten business operations. Therefore, it is widely recommended businesses respond to climate change and implement climate change adaptation. Worldwide, businesses make efforts towards climate change adaptation, but investigation on such efforts is still required. To partially fill this research gap, the paper explores businesses adaptation efforts in the Hunter Valley, Australia. The paper collects primary data from open-ended interviews to 10 representatives of local businesses and supporting organizations. The paper reveals that businesses interpret climate change in different ways. While some businesses are sceptical about climate change, others are aware of it and its impacts on everyday operations. Businesses therefore implement adaptation by integrating climate change into everyday operations and continuity planning. The paper also shows diverse interactions occurring between businesses and other local stakeholders such as governments and communities. Usually, higher government levels offer vague and limited support to businesses and inhibit their adaptive efforts. Meanwhile, interactions between businesses and City Councils can be both collaborative and fragmented. Some businesses also interact with local communities by disclosing information about their operations and response to climate change. The paper discusses these findings and provides conclusions under the form of recommendations for policy and research on Australian businesses and climate change adaptation. [ABSTRACT FROM AUTHOR]

This paper uses a 30 m record of valley alluviation in the Lockyer Creek, a major tributary of the mid-Brisbane River in Southeast Queensland, to document the timing and nature of Quaternary fluvial response. A combination of radiocarbon and optically stimulated luminescence dating reveals a sequence of major cut and fill episodes. The earliest aggradation phase is represented by a basal gravel unit, dating to ~220 ka (marine isotope sub-stage 7d), and although little evidence supports higher fluvial discharges during MIS 5, a MIS 3 fluvial episode characterised by incision and aggradation dates to ~60 ka. A penultimate phase of incision to a depth of 30 m prior to ~14 ka saw the lower Lockyer occupy its current position within the valley floor. The Lockyer Creek shows evidence of only minor fluvial activity during MIS 2, suggesting a drier LGM climate. The appearance of alternating fine- and coarse-grained units at about 2 ka is notable and may represent higher-energy flood conditions associated with a strengthening of El Niño Southern Oscillation activity as observed in the flood of 2011. The aggradation rate for this Holocene floodplain unit is ~11 times higher than the long-term rate. [ABSTRACT FROM AUTHOR]

Rehabilitation of post-mining sites in semi-arid/subtropical environments of eastern Australia have a general objective to establish specific types of native vegetation communities as defined in mine closure plans and in relation to the specific biotic and abiotic requirements of such communities. Critical for the success of rehabilitation is the availability of water and hence the climatic characteristic of this geographical region which is defined by a number of weather-bound factors (e.g. potentially erratic rainfall and periods of drought and flooding). However, specific estimates of climate suitability are seldom incorporated into current mined land rehabilitation design. To address this, our analysis combined various broad-scale climatic parameters (i.e. primarily relating to rainfall) to assess bioregional suitability-susceptibility within the context of plant early-establishment in the objective of informing rehabilitation schemes as to the inherent environmental challenges influencing both short- and long-term ecological development. Following our survey of available climate data, we derived site suitability-susceptibility indexes (that are otherwise currently not available within rehabilitation schemes) and compared the performance of 9 mine site locations in which our Centre has been engaged in environmental monitoring (Weipa, Mt. Isa, Ernest Henry, Eromanga, Kidston, Curragh, Tarong, North Stradbroke Island, and Newnes Plateau). More specifically, the sites were ranked from most-to-least suitable and compared with natural vegetation patterns (as estimated by the mean NDVI). Overall, it was determined that regular rainfall and relatively short periods of water-deficit are key characteristics of climate suitability (as found among the relatively more temperate coastal-hinterland sites), whereas high rainfall variability and (or) prolonged seasonal drought are primary characteristics of unsuitability (as found among the arid central-inland sites). Conceptual and practical considerations are provided which could inform rehabilitation schemes as to the inherent environmental challenges influencing both short- and long-term ecological development.

Herein, Professor Barrie updates his 2016 presentation to the Institute on the national security implications of climate change. He notes that, despite a 2017 Senate inquiry urging urgent action, the Commonwealth Government has not yet responded other than by acknowledging the issue in a 2016 Defence white paper and a 2020 strategic update. The latest scientific research indicates that, in the worst case, Earth may reach a climate tipping point within 18 months which would pose an existential threat to humankind. Short of an existential threat, no other country on the planet will be as affected by the consequences of climate change as Australia. Time is running out for Australia to act!.

The article presents a research which investigates the proposed framework for downscaling coarse climate change projections for oceans in the Australian region. It explores significance of the downscaling model in projecting marine impacts of climate change. The restoration of the ocean feedback on the air-sea fluxes to surface temperature and salinity is explored. It notes that the framework offers an attractive way to explore the impact of climate change on mesoscale ocean environment.

Antarctica is a crucial regulator of the world's climate, and as environmental security permeates global security, using Antarctic science to better understand climate is becoming increasingly pressing. Although the Australian Government has recognised that climate change poses 'a current and existential national security' threat and has acknowledged Antarctica's importance regarding the earth's global climate system, the focus of Australia's intelligence community pertaining to Antarctica currently remains restricted to upholding the military-security and diplomatic goals of the Antarctic Treaty System (ATS). This current focus aims to hedge against the possibility of conflict on, or over, the frozen continent via 'working the ATS', however, this paper argues that Antarctic climate science holds a greater capacity to deliver security outcomes for Australia. Antarctic climate science offers opportunities regarding intelligence for Antarctica, that is, securing Australia's Antarctic interests, as well as regarding intelligence from Antarctica; by enhancing natural disaster preparedness, bolstering broader strategic planning, as well as furthering diplomacy and the legitimisation of Australia's leadership on, and over, the frozen continent. It is recommended that the Commonwealth Government establish a climate intelligence working group to ensure the utility of climate science to security and intelligence is realised.

This paper starts from the point that our current political‐economic‐climate conjuncture demands new engagements at the dynamic interface of climate capitalism. Using two cases of climate capitalist responses to climate challenges, I demonstrate the reparative potentials that emerge from the tensions and ambiguities that typify that conjuncture. In the first case, I examine financialised climate infrastructure in Jakarta, Indonesia, that promises to protect the city from flooding while enriching city elites, but against which diverse social movements and collectives have organised. The second case is about a cooperative energy provider in Australia, operating on the terrain of a neoliberalised electricity market and climate change, and working towards multifaceted repair by collectivising and redistributing surplus and modelling democratic engagement. Those involved in these vastly different cases both pursue repair and reparations through climate capitalist projects by reckoning with historical and present climate debts while constructing forward‐looking programs. As such, they chart the first steps towards reparative climate futures. This paper identifies the political and socioecological potentials from two key climate capitalist projects: flood protection infrastructures in Jakarta and cooperative energy in Australia. From this, it builds a framework of repair and reparations for engaging with climate capitalism and argues that the emerging tensions and ambiguities facilitate steps towards reparative climate futures.

Sustainable food practices are increasingly of interest to scholars and practitioners concerned with the impacts of food production, consumption, and waste in an age of climate change. Attention has been paid to households as actors in addressing sustainability concerns. This paper draws on a national survey of Australian sustainable household practices to offer insights into the ways households are practicing sustainability across three everyday entanglements with food: (1) growing food, (2) consuming food and (3) wasting/disposing of food. The paper explores the types of practices enacted across the three entanglements and provides an understanding of the prevalence and barriers for households adopting sustainable food practices.

Animals on a grand scale are victims of climate change and of natural disaster. With no voice within human cultures, their plight can be silenced and forgotten once an extreme weather event is over and when media coverage of the devastation has ceased. The creative arts have an important role to play in raising public awareness of and empathy for animals impacted by natural disaster. This paper presents a critical discourse analysis of the Australian play Fire by Scott Alderdice (2017), framed by Animal Studies perspectives. The voices of the animals in Fire, as expressed through language -- dialogue and narration -- are the focus of the analysis to determine how the play engages in the concepts of considering other-than-human interests; imagining and representing animals and their significance; personifying species' presence using human speech to offset facelessness; and inspiring humans to take responsibility in this time of climate crisis and natural disaster. Fire provides an exemplar for theatrical expression giving voice to animals in times of crisis. An examination of the narration and dialogue of the animal characters reveals a respectful representation of native Australian animals, who are shown to be sentient and social beings intimately entwined with the environment in which they live. The language use by the animals throughout elicits recognition and empathy and subsequently feelings of grief and of guilt. The play inspires humans to take responsibility by considering animals' perspectives and interests; understanding their significance in the world; and performing our role to protect the natural environment.

South eastern Australia is a global warming hotspot, and is also home to ~70% of Australia's population and one of Australia's largest fisheries—the South East Scalefish and Shark Fishery. This fishery spans shelf to deep waters, subtropical to temperate waters, employs many gears, and interacts with over 100 species. Despite following best practice fisheries management principles, including taking an ecosystem perspective to overall fisheries interactions, management interventions have failed to arrest or recover the decline of some focal species. Using an Atlantis ecosystem model developed for the fishery over the past 20 years, this paper presents simulations that suggest climate change may be a major contributor to the trajectories seen for a number of species—such as jackass morwong (Nemadactylus macropterus), blue warehou (Seriolella brama), and gemfish (Rexea solandri). This kind of climate influence poses many challenges for fisheries management into the future, raising questions about what to do when climate change undermines or overrides fisheries management actions and objectives.

Terrorism and climate change debates are often characterized by worst‐case thinking, cost neglect, probability neglect, and avoidance of the notion of acceptable risk. This is not unexpected when dealing with extreme events. However, it can result in a frightened public, costly policy outcomes, and wasteful expenditures. The paper will describe how risk‐based approaches are well suited to infrastructure decision‐making for extreme events. Risk management concepts will be illustrated with current research of risk‐based assessment of climate adaptation engineering strategies including designing new houses in Australia subject to cyclones and extreme wind events. It will be shown that small improvements to house designs at a one‐off cost of several thousand dollars per house can reduce damage risks by 70%–80% and achieve billions of dollars of net benefit for community resilience—this helps offset some the predicted adverse effects of climate change for a modest cost. The effect of risk perceptions, insurance, and economic incentives is explored for another climate adaption measure. The paper will also highlight that there is much to be optimistic about the future, and in the ability of risk‐based thinking to meet many challenges. [ABSTRACT FROM AUTHOR]

Projections for the number of people displaced by climate change globally are startling and vary from 100 million to 1 billion; however, a widely repeated prediction is for 200 million by the mid-twenty-first century. Although difficult to estimate, some proportion of these people will cross borders and end up in Global North countries. This paper offers a provocation on the implications for Australian cities. It reviews Australia's significant strategic planning policies in light of a possible mid-future surge in environmental migrants and considers how such policies could better prepare Australian cities. The paper concludes that a National Urban Policy could strengthen strategic preparedness for environmental migration. [ABSTRACT FROM AUTHOR]

Summary: We synthesise the findings from 10 years of ecological restoration in the Midlands of Tasmania, Australia, captured in the series of 14 papers in this special issue of Ecological Management and Restoration. The papers illustrate how expertise from disciplines as diverse as law, economics, social sciences, the arts, education, zoology, botany, genetics, climate modelling, agriculture, spatial sciences and fire ecology are necessary to address the complex social, ecological and financial questions that underpin restoration ecology. We highlight the complexity of the task, the multi‐disciplinary and collaborative approach needed, the importance of science to inform restoration practice and the problem of achieving functional connectivity. We also outline steps that need to be taken in the next 10 years. Together, the outcomes and recommendations from these studies provide a template for restoration in similar highly cleared and degraded agricultural landscapes affected by climate change in Australia and internationally.

Introduction: It is well-established that heatwaves increase demand for emergency transport in metropolitan areas; however, little is known about the impact of heat events on demand for prehospital retrieval services in rural and remote areas, or how heatwaves are defined in this context.Inclusion Criteria: Papers were eligible for inclusion if they reported on the impact of a heat event on the activity of a prehospital and retrieval service in a rural or remote area.Methods: A search of PubMed, Cochrane, Science Direct, CINAHL, and Google Scholar databases was undertaken on August 18, 2020 using search terms related to emergency medical transport, extreme heat, and rural or remote. Data relevant to the impact of heat on retrieval service activity were extracted, as well as definitions of extreme heat.Results: Two papers were identified, both from Australia. Both found that heat events increased the number of road ambulance call-outs. Both studies used the Excess Heat Factor (EHF) to define heatwave periods of interest.Conclusions: This review found almost no primary literature on demand for prehospital retrieval services in rural and remote areas, and no data specifically related to aeromedical transport. The research did recognize the disproportionate impact of heat-related increase in service demand on Australian rural and regional health services. With the effects of climate change already being felt, there is an urgent need for more research and action in this area. [ABSTRACT FROM AUTHOR]

Global municipal solid waste (MSW) amounts to approximately 1.3 billion tons per year and is expected to increase to approximately 2.2 billion tons per year by 2025. The greenhouse gas (GHG) emissions from landfills contribute to global climate change. Emissions from this sector contribute around 3% of total net emissions in Australia. Although responsible for a minor portion of Australia's emissions, the sector provides the opportunity for low-cost sources of abatement. This research study aimed to identify new opportunities for reducing GHG emissions from the landfill waste stream in public facilities in Blacktown City in New South Wales, Australia. For this purpose, two public facilities of different types were selected, a library and an aquatic center. The results of the study show that removing organic food waste from the landfill stream at 10 public facilities of the Council could reduce GHG emissions compared with landfilling the food waste by about 0.805 tCO2e/year. However, separately transporting that waste would emit 7.13 tCO2e/year. Therefore, the separated food waste would need to be processed on-site, for example, through worm farms. Removing coffee cups from the landfill waste stream could reduce the associated landfill GHG emissions by around 0.275 tCO2e/y for the 10 public facilities. The study also recommended separating plastic bags from the landfill waste stream of these facilities to reduce 1.10 tonnes of plastic bags from landfill each year. Implications: Potential opportunities for general waste reduction and GHG emission mitigation in public facilities has been studied in this paper. Removing coffee cups and organics food from the waste stream are the main potential opportunities for reducing general waste with possible GHG emission reduction of 0.275 tCO2e/y and 0.161 tCO2/y respectively for 10 public facilities. Removing plastic bags from the waste stream would offer another solution for waste reduction by jointing with the large program running in Australia and creating a collection point for them with 1.1 tonne/y mitigation in general waste at 10 studied public facilities.

Although a growing body of literature studies drought impacts, papers providing a comprehensive review of drought's social and economic impacts are scarce. This paper fills this gap by exploring the consequences of drought on societies based on research findings in Australia—a large country used to experiencing severe droughts. To do this, we propose a framework to categorise drought impacts in three dimensions: individuals/households (including health), productive sectors and system (including economic and ecosystem) impacts. The framework then guides a systematic literature review and discussion of studies looking at diverse drought impacts and their related costs. By analysing and discussing the findings from this literature, we emphasise different policy considerations, empirical challenges and research needs to support robust analysis and estimates of the true cost of droughts. We conclude by proposing an expanded framework to identify drought impacts and a discussion of the implications of the review for policy development. [ABSTRACT FROM AUTHOR]

Simple Summary: Existing food production systems and dietary behaviours are not healthy nor sustainable due to the higher environmental footprint of animal-derived foods. Alternative dietary choices could provide better outcomes. We investigated Generation Z (Gen Z)'s alternative food preferences within a planetary health framework which combines human and ecological well-being. The paper is based on data from a 2021 cross-national survey conducted in the main Australian cities, which explored Gen Z's attitudes towards meat consumption in relation to climate change and alternatives to animal-based proteins. Climate change is seen as a result of human activities by 86% of the survey participants. More than a third (38%) of them believe that livestock production and the consumption of animal-sourced foods are contributing significantly to climate change and environmental deterioration. The remaining majority (62%), however, has a low awareness and understanding of the food systems' impacts, disbelieving that diet is a major contributor to climate change. We discuss how these findings will shape Australia's Gen Z, climate change and the future of alternative proteins. Scientific evidence shows that current food systems are impacting the planet in ways that are unsustainable and detrimental to human health. Various technological advances have been made in response, one of them being the development of new food products known as novel alternative proteins, including cultured meat, plant-based meat analogues, algae- and insect-based foods. The future of these alternative proteins to a large extent depends on consumer acceptance from young people. This study investigates the attitudes of Australia's adult Generation Z (Gen Z), born between 1995 and 2003, regarding climate change and more sustainable food choices. Gen Z is a diverse, important and trendsetting group known for organising globally on causes related to climate, social justice and health. The study of Australia's Gen Z is based on a 2021 cross-national survey in the main Australian cities. It shows that, although 86% of the participants perceive climate change as anthropogenic, only 38% believe that livestock-based foods are contributing significantly to global warming and environmental deterioration. The paper discusses the implications for Gen Z and novel alternative proteins given that the majority of Australia's young people has low awareness of the environmental impacts of food systems and dietary choices.

The Australian Institute for the Conservation of Cultural Material has published a range of resources that promote environmentally aware collection care and management practices including climate-specific Environmental Guidelines, the Sustainable Collections wiki and the Climate Adaptation resource. The Climate Adaptation resource provides access to 180 maps illustrating potential future climate scenarios for Australia in 2030 and 2090, using the two Representative Concentration Pathways RCP4.5 and RCP8.5. These maps were produced as part of research undertaken in 2019–2020 by Pagliarino and Meredith and supplement those published in volume 41 (issue 1) of the AICCM Bulletin. The release of updated climate change projections in the Sixth Assessment Report from the Intergovernmental Panel on Climate Change (IPCC) – Climate Change 2021: The Physical Science Basis – precipitated a review of the Climate Adaptation resource to confirm the continued veracity of the maps. This paper provides the results of that assessment, which confirmed the resource's ongoing accuracy and currency. In addition, the paper includes discussion of the new IPCC future climate scenarios of Shared Socioeconomic Pathways, which supersede RCP, and a summary of the state of the climate in Australia with warming, humidity, fire, weather and sea level rise investigated in more detail.

Culturally modified trees (CMTs) are a unique form of archaeology and cultural heritage. There are several factors affecting the survival of culturally modified trees in Australia, and these will all likely be exacerbated by climate change. Boab trees (Adansonia gregorii), which are endemic to northwest Australia, have been subject to modification by Indigenous people both prior to and following the settlement of the Kimberley region by European and Anglo-Australians. Many of the potential impacts of climate change on boab tree survival are yet to be determined, but a range of new threats are emerging as potential endangerment. Through the insights of Indigenous knowledge, this paper discusses one particularly significant boab tree in Nyikina Country and how its demise may be linked to erroneous human actions in the recent past. This provides a unique perspective on how the complexities of climate change may be conceptualised through living knowledge and experience. [ABSTRACT FROM AUTHOR]

Convergent environmental crises have triggered scholarly attention towards the question of how great powers understand and engage with the environment, given their role as systemic actors within the international order. Environmental great powers – those that can employ both positive and negative powers to advance or block environmental cooperation – are typically limited to those who have the capability to influence environmental issues, and the responsibility to do so legitimately. Using a constructivist lens, this paper extends this analysis to the role of middle powers, who can influence environmental issues through their support for international cooperation, backed by their actions. We focus on Australia, an oft-cited middle power known for supporting the international rules-based order. By examining Australia's record on two current, interlinked environmental crises, climate change and biodiversity, we show that although it provides legal support for environmental cooperation, it also engages in, and conceals, significant political obstruction to meeting its obligations. Given the need for all states to address the surpassing of safe limits of planetary boundaries, and for its contribution to the destruction of systems upon which humanity depends, we argue that Australia might be deemed an ecocidal middle power.

Wildfires pose a severe threat to the ecosystem and economy, and risk assessment is typically based on fire danger indices such as the McArthur Forest Fire Danger Index (FFDI) used in Australia. Studying the joint tail dependence structure of high-resolution spatial FFDI data is thus crucial for estimating current and future extreme wildfire risk. However, existing likelihood-based inference approaches are computationally prohibitive in high dimensions due to the need to censor observations in the bulk of the distribution. To address this, we construct models for spatial FFDI extremes by leveraging the sparse conditional independence structure of Hüsler–Reiss-type generalized Pareto processes defined on trees. These models allow for a simplified likelihood function that is computationally efficient. Our framework involves a mixture of tree-based multivariate generalized Pareto distributions with randomly generated tree structures, resulting in a flexible model that can capture nonstationary spatial dependence structures. We fit the model to summer FFDI data from different spatial clusters in Mainland Australia and 14 decadal windows between 1999 and 2022 to study local spatiotemporal variability with respect to the magnitude and extent of extreme wildfires. Our proposed method fits the margins and spatial tail dependence structure adequately and is helpful in providing extreme wildfire risk estimates. Our results identify a significant increase in spatially aggregated fire risk across a substantially large portion of Mainland Australia, which raises serious climatic concerns.

The politics of climate change in Australia remains highly fraught, this is despite the country experiencing acute impacts of a changing climate including mega-fires, floods, and severe and prolonged drought. Government inaction has led to limited market signals encouraging producers or consumers to move away from carbon intensive energy production to clean energy. In the absence of regulation, Australian shareholder activists are engaging directly with company boards and executives to reform corporate behaviour. This engagement, environmental, social, and governance (ESG) shareholder activism, has proliferated since 2017, much later than in comparable jurisdictions. Activists have targeted the mining, oil and gas, and finance sectors, due to their contribution to the Australian economy and their direct impact on global emissions. This paper explores the reasons for, and the implications of, the growth in ESG shareholder activism in Australia. It argues that the emergence of this activism in Australia was delayed due to complexities in the country's corporations' law. Regulatory attempts at stymying ESG shareholder activism resulted in the emergence of a duopoly of actors, at the cost of broader investor and civil society engagement. It is concluded that the rise of ESG shareholder activism in Australia is linked to growing tension between societal expectations, regulation, and the behaviour of firms. And, that ESG activists have been successful in leveraging this tension. There is evidence that large corporates have responded to activist claims, rendering this form of activism a potentially effective method for addressing some of the most pressing issues facing society.

This paper summarises key issues from papers included in a special issue about the impacts of climate change on Australian wetlands. The papers covered: the assessment of wetlands under climate change, adaptation and engineering responses to climate change, and restoring wetlands under a changing climate. The key issues from these papers were used to indicate areas where the Ramsar Convention could develop guidance as part of its' Handbooks for the Wise Use of Wetlands. These included: (i) assessing changes in the distribution of species and whether these constitute a change in the ecological character of the wetland; (ii) assessing the usefulness of models of wetland response to climate change; (iii) assessing the value in allocating water to protected sites where restoration would be contingent on reallocation of larger volumes of water; (iv) assessing the efficacy of engineering responses with the potential to deliver more water-efficient environmental outcomes for wetlands and (v) determining if the description of the ecological character of a Ramsar site at the time of listing is a suitable reference for management purposes. With these issues in mind it is recommended that further attention is directed towards determining and responding to the ecological consequences of climate change. [ABSTRACT FROM AUTHOR]

Climate change represents the grandest of challenges facing humanity. In the space of two centuries of industrial development, human civilization has changed the chemistry of the atmosphere and oceans, with devastating consequences. Business organizations are central to this challenge, in that they support the production of escalating greenhouse gas emissions but also offer innovative ways to decarbonize our economies. In this paper, we examine how businesses respond to climate change. Based on five in-depth case studies of major Australian corporations over a 10-year period (2005-2015), we identify three key stages in the corporate translation of climate change: framing, localizing, and normalizing. We develop a grounded model that explains how the revolutionary import of grand challenges is converted into the mundane and comfortable concerns of "business as usual." We find that critique is the major driver of this process by continuously revealing the tensions between the demands of the grand challenge and business imperatives. Our paper contributes to the literature on business and the natural environment by identifying how and why corporate environmental initiatives deteriorate over time. More specifically, we highlight the policy limitations of a reliance on business and market responses to the climate crisis. [ABSTRACT FROM AUTHOR]

The repeated occurrence of natural disasters is impacting communities globally and these effects are expected to worsen as the global temperatures continue to rise. In Australia, communities on the East Coast are now bracing for another dry hot summer along with the accompanying threat of bushfire. In this context, many governments have promoted the idea of building resilient communities in order to try to mitigate the danger and threat to communities. The idea of enhancing resilience is both appealing and problematic: appealing, because it signifies the power of the human spirit to overcome adversity: problematic, because such a term can easily be exploited to support ideological beliefs about independence and self-sufficiency. This paper explores the notion of enhancing resilience in smaller rural communities, specifically in the context of recovery from the fires in 2019/2020. By adopting a case study approach, we argue first, that whilst the idea of resilience has value, it needs to be equalised by a robust understanding of the contextual factors that may increase vulnerability (Solangaarachchi Griffin & Doherty, 2012); with this in mind, we suggest that developing adaptive capacity is more fitting because of the way it draws our attention to the changes that are necessary for responding to the changes in climate. Second, we argue that if communities are to be assisted to adapt in order to survive the effects of climate change, this work will require an increased focus on community development in the medium and long-term stages of recovery, so that communities are assisted, supported and empowered to engage preparedness projects in the event of disasters occurring in the future.

Wildfires affect 40% of the earth's terrestrial biome, but much of our knowledge of wildfire activity is limited to the satellite era. Improved understanding of past fires is necessary to better forecast how fire regimes might change with future climate change, to understand ecosystem resilience to fire, and to improve data-model comparisons. Environmental proxy archives can extend our knowledge of past fire activity. Speleothems, naturally occurring cave formations, are widely used in paleoenvironmental research as they are absolutely dateable, occur on every ice-free continent, and include multiple proxies. Recently, speleothems have been shown to record past fire events (Argiriadis et al., 2019, https://doi.org/10.1021/acs.analchem.9b00767; McDonough et al., 2022, https://doi.org/10.1016/j.gca.2022.03.020; Homann et al., 2022, https://doi. org/10.1038/s41467-022-34950-x). Here we present a review of this emerging application in speleothem paleoenvironmental science. We give a concise overview of fire regimes and common paleofire proxies, describe past attempts to use stalagmites to investigate paleofire, and describe the physical basis through which speleothems can record past fires. We then describe the ideal speleothem sample for paleofire research and offer a summary of applicable laboratory and statistical methods. Finally, we present four case studies from southwest Australia which: (a) explore the geochemistry of ash leachates, (b) detail how sulfate isotopes may be a proxy for post fire ecological recovery, (c) demonstrate how a catastrophic paleofire was linked to changes in climate and land management, and (d) investigate whether deep caves can record past fire events. We conclude the paper by outlining future research directions for paleofire applications. Wildfires are a global hazard, and are likely to become larger, more common, and more intense with climate change. Most of our knowledge about wildfires comes from satellite data, which are not long enough to fully understand past fire behavior. We can use paleoenvironmental data to learn more. Natural cave decorations (speleothems) have recently been found to include information about fire events. As they grow, stalagmite chemistry changes according to the climate and environment, and recent research has shown that elements from wildfire ash can become incorporated into the speleothem archive. Here we review recent advances of this new application in paleofire research. We detail the development of this emerging field, starting with cave dripwater monitoring results, we then give an overview of relevant laboratory and statistical methods, and provide four case studies. The case studies are an investigation of ash geochemistry, an analysis of post-fire changes in sulfate, a study of how intense fires are linked to climate, and an exploration of whether deep cave stalagmites may also record past fires. Longer records of fire activity will help to improve models for forecasting how fire regimes might change with climate change and how ecosystems might respond to those changes.

Societies are now squarely facing the risks of environmental and climatic change, and developed coastlines are ground zero. Climate change will cause damage to, or loss of, coastal property – property that, in most Western societies, is considered a high net value asset. This paper examines cultural ideas about private property and the complexities of using land use planning law as an enabler of climate change adaptation. It reports the findings of qualitative research that explores how residents living in coastal Australia respond to the risks to their property and to the places they live that are posed by sea level rise and other coastal climate change‐related risks. By reporting how residents experience their material coastal environment, and how they relate with and to ideas of "property" in a coastal environmental change context, this paper contributes to both coastal policy and to legal geography scholarship.

Bushfires are a global climate change challenge and a critical disaster issue for Australia. Adaptive governance has emerged as a model to address socio-ecological issues such as disasters. This paper discusses four principles of adaptive governance: polycentric institutions, collaboration, social learning, and reflexivity and examines how these are reflected in the policy and practice of bushfire management in the South West of Australia. Findings demonstrate that current disaster policy discourse, which influences bushfire management, increasingly advocates for principles associated with adaptive governance. However, a case study on the Shire of Augusta-Margaret River found that the extent to which these principles translate into bushfire management practice is largely influenced by interpretive worldview policy frames. The paper suggests that governance for bushfire management could become more adaptive in its approach by incorporating more collaborative management activities, deliberative policy processes and reflexive practice.

There has been a global trend away from delivering 'climate information' towards producing 'climate services' for decision-makers. The rationale for this shift is said to be the demand for timely and actionable climate knowledge, whilst the means of its delivery involves a shift from public good to more privatised forms of climate science. This paper identifies important implications of this shift to climate services by examining the role of consultants, drawing on an in-depth study of adaptation consultants in Australia. The role of consultants is instructive, not just because these private sector experts are engaged in climate services, but also because publicly funded climate science agencies are increasingly encouraged to behave as consulting firms do. Four imperatives of knowledge businesses—to be client-focussed, solutions-oriented, resource-efficient and self-replicating—are described. The paper argues that an emphasis on climate services shifts the incentives for climate science away from the public interest towards the ongoing pursuit of profit. There is a subsequent diversion of effort away from publicly accessible and transparent climate information to private knowledge for discrete clients. Climate services also emphasise knowledge for climate solutions as opposed to the politically charged identification of climate risks. The paper concludes with a warning that the trend towards climate services undermines the knowledge required for societies to adequately respond to the scale, speed and severity of climate change. At the heart of this issue is a climate services paradox: how to achieve customisation without exclusion. [ABSTRACT FROM AUTHOR]

The Australian federal government white paper 'Our north, our future' projects that northern Australia's population could reach 5,000,000 by 2060. This represents an almost four-fold increase in population (an additional 3,700,000 people) all within the next 41 years. Given the ambiguities in the White paper about the distribution of this population, this paper ventures three settlement pattern scenarios to explore the issues these may pose. The paper concludes that population growth of the scale projected will require comprehensive, long term planning – without such planning the scale of population growth projected could result in negative environmental and societal consequences. As such, the discipline of planning in Australia should be aware of this emerging situation. [ABSTRACT FROM AUTHOR]

In the 2016 Climate Action Network Europe review of national climate policies, Australia once again was one of the lowest at 57 out of the 61 countries. Australia's policies were critiqued for being "unambitious and uninspired". Numerous studies show that policies are often the key way to address human activity that harmfully warms the climate. Therefore Australia's unambitious policies require re-evaluation. Furthermore, taxes are a predominant way in which emissions can be reduced. Consequently this paper explores some of Australia's environment-related tax policies to determine what has best ameliorated humanity's affect on climate change in Australia. The paper carries out its evaluation of Australian environmental taxes by using the Institute of Fiscal Studies' behavioural economics-based framework (IFS Framework). The IFS Framework represents a formal attempt to integrate behavioural economics into tax policy analysis. Although extensive, in-depth analysis of Australia's environmental tax policies using traditional economic frameworks exists, there is little analysis using ideas from behavioural economics. Therefore the IFS Framework's use of behavioural economics presents an opportunity to evaluate Australia's environmental taxes in a new light. The paper analyses five Australian environment and tax related policy initiatives: the Sydney Harbour Bridge congestion charge (Harbour Bridge Charge); the abolished Emissions Trading Scheme (ETS); the new Emissions Reduction Fund with its safeguard mechanism (Safeguard Mechanism); environmental tax cases; and pro-compliance messaging. The paper's evaluation of these initiatives begins by referring to what insights the IFS Framework says behavioural economics has for that kind of policy initiative. Then the paper explores whether the initiative incorporates those insights. The paper therefore suggests ways that Australia's taxation policy can become more ambitious and inspired with respect to environmental concerns. [ABSTRACT FROM AUTHOR]

Summary: Natural resource management in Australia is beset with 'wicked' problems: diminishing biodiversity, increasing soil erosion, spreading soil salinity and global climate change all impact private landholders across rural Australia. These problems highlight the complexity of biodiversity conservation, and the need for inclusive, respectful approaches that enable the participation of rural communities, private landholders and government agencies to effectively manage biodiversity on public and private lands. To address these problems, some landholders, rural communities and other stakeholders are seeking evidence‐based solutions through directly applicable research. In this paper, we identify current barriers to such research and highlight principles and processes for co‐designing and managing research based on mutual trust, respect, power sharing and acceptance of various knowledge systems, as embodied in the theory of reconciliation ecology. We suggest that a 'community of practice' approach could assist in establishing effective deliberative relations as a basis for active collaboration in natural resource management research to address these complex problems.

This paper presents the provocation that 'unmediatised liveness', or experiences not filtered through digital technology, is vital to performances that promote recovery, resistance, and survival among young people in response to the climate crisis. Our provocation draws from interviews conducted with youth theatre and performance practitioners in Australia whose work addresses the climate crisis holistically across disaster preparedness, first response, disaster recovery, and climate activism. We argue that while mediatised interactions remain a critical element of contemporary youth culture and performance, unmediatised co-presence, artistic collaboration, community action, and activism are crucial in the high-stakes context of Australia's climate crisis.

Climate change is impacting people's lives, with management of water resources and food security being major concerns for the future of many countries. In this paper, future water availability, crop water needs, yields, market costs and returns of current crops in a case study area in Australia are evaluated under future climatic conditions. The predictive methods on which the work is based have the advantage of being robust—they are able to simultaneously consider many climate change models—giving greater confidence in determining what the future will hold in this regard. The results indicate business as usual, in terms of the quantity and types of crops that can be grown presently, will not be sustainable in the medium and long term future. Instead, modelling indicates that changes in production and land use to maximise revenue per megalitre of water will be needed to adapt to future conditions and deliver climate-smart agriculture.

There is a growing body of research documenting Indigenous Peoples and Local Communities' observations of changes in climate. The accuracy, efficacy, and transferability of this research depends on its motives and methods. In this paper, we report on research to produce a working knowledge of changes in climate and its impacts on local biophysical systems in the Tiwi Islands in Northern Australia. Interviews with 52 Tiwi people were combined with diverse forms of aerial data to produce a nuanced understanding of climate change in these remote islands. These data show changes in climate‐sensitive biophysical systems that would otherwise remain undetected by instruments conventionally used for monitoring climate change. These include changes in shorelines, which are causing concerns about damage to buildings that are important for Tiwi well‐being, and changes in the marine environment and wetlands, which are causing concerns about damage to natural heritage. We discuss the implications of these findings, arguing that systematic observations collected by networks of people "on Country" can provide excellent monitoring of climate change impacts, and that Indigenous people's interests in the effects of climate change overlap with those of non‐Indigenous people, as do their rights to support from the State for adaptation. Plain Language Summary: Research that documents Indigenous and local people's observations of changes in the environment is essential to understand the broader implications of climate change. The observations reported in this study in the Tiwi Islands (Northern Territory, Australia) show environmental changes that would otherwise remain undetected by instruments conventionally used for monitoring climate change, particularly changes that affect crucial infrastructure, as well as changes in the marine and coastal environment. Tiwi Islanders observations help monitoring climate change impacts while reaffirming the rights of Indigenous peoples to get support for climate change adaptation from the State. Key Points: Tiwi people observe nuanced changes in the environment that are significant to them, and for understanding the impacts of climate changeTiwi people express concern about the risks of coastal erosion to buildings that are important for their daily lives and livelihoodsIndigenous people's interests in adaptation overlap with those of non‐Indigenous people, as do their rights to support for adaptation [ABSTRACT FROM AUTHOR]

This paper proposes a conceptual framework for climate policy engagement that is focused on building the social conditions conducive to support for climate policy. Despite the ongoing scientific and social cases being made for climate action, social divisions remain in some contexts such as Australia and the United States. The success of climate policies depend in part on the general social support base for that solution, with public polarisation acting as a barrier. Dominant communication models have tended to rely on one-way strategically focused communication to exert influence with the aim of shifting one's attitudes. However, there is a need to extend such approaches to go beyond strategic messaging and instead establish the social conditions necessary for policy support. Drawing on diverse literature and framing theory, a new engagement model for climate policy is proposed which centres around a goal of relationship-building between actors to facilitate productive discussion on climate policy.
