Abstract Anthropogenic greenhouse gas emissions change earth’s climate by altering the planet’s radiative balance. An important first step in mitigation of climate change is to reduce annual increases in these emissions. However, the many suggested means of limiting emissions rates have led to few actual changes in policy or behavior. This disconnection can be attributed in part to the difficulty of convening groups of stakeholders with diverse values, the polarizing nature of current political systems, poor communication across disciplines, and a lack of clear, usable information about emission mitigation strategies. Here, electronically facilitated ethical deliberation, a method of determining courses of action on common goals by collaborative discussion, is used to evaluate Pacala and Socolow’s climate change stabilization strategies based on economic, technological, social, and ecological impacts across a wide range of spatial and temporal scales. Few previous analyses of climate mitigation strategies include all of these factors; rather, short-term technological feasibility studies and economic cost–benefit analyses predominate. After accounting for tradeoffs among disparate criteria, strategies involving end-user efficiency (e.g., efficient buildings and vehicles), wind, and solar power rank highest, while carbon capture and storage, hydrogen fuel cells, and biofuels options rank lowest. This electronically facilitated deliberation method offers an alternative to oppositional debate or cost–benefit analysis for assessing strategies where both quantitative and qualitative factors are important, information from disparate disciplines is relevant, and stakeholders are geographically dispersed.

The Impact

Every aspect of human operations faces a wide range of risks, some of which can cause serious consequences. By the start of 21st century, mankind has recognized a new class of risks posed by climate change. It is obvious, that the global climate is changing, and will continue to change, in ways that affect the planning and day to day operations of businesses, government agencies and other organizations and institutions. The manifestations of climate change include but not limited to rising sea levels, increasing temperature, flooding, melting polar sea ice, adverse weather events (e.g. heatwaves, drought, and storms) and a rise in related problems (e.g. health and environmental). Assessing and managing climate risks represent one of the most challenging issues of today and for the future. The purpose of the risk modeling system discussed in this paper is to provide a framework and methodology to quantify risks caused by climate change, to facilitate estimates of the impact of climate change on various spheres of human activities and to compare eventual adaptation and risk mitigation strategies. The system integrates both physical climate system and economic models together with knowledge-based subsystem, which can help support proactive risk management. System structure and its main components are considered. Special attention is paid to climate risk assessment, management and hedging in the Arctic coastal areas.

Climate change means that buildings must greatly reduce their energy consumption. It is however paradoxical that climate mitigation in Denmark has created negative energy and indoor climate problems in housing that may be made worse by climate change. A literature review has been carried out of housing schemes where climate mitigation was sought through reduced space heating demand, and it is shown that extensive problems with overheating exist. A theoretical study of regulative and design strategies for climate mitigation in new build housing has therefore been carried out, and it is shown that reducing space heating with high levels of thermal insulation and passive solar energy results in overheating and a growing demand for cooling. Climate change is expected to reduce space heating and increase cooling demand in housing. An analysis of new build housing using passive solar energy as a climate mitigation strategy has therefore been carried out in relation to future climate change scenarios. It is shown that severe indoor comfort problems can occur, questioning the relevance of passive solar energy as a climate mitigation strategy. In conclusion, a theoretical study of the interplay between climate adaptation and mitigation strategies is carried out, with a cross-disciplinary focus on users, passive design and active technologies. It is shown that the cumulative use of these strategies can create an adaptation buffer, thus eliminating problems with overheating and reducing energy consumption. New build housing should therefore be designed in relation to both current and future climate scenarios to show that the climate mitigation strategies ensure climate adaptation.

Abstract. While climate change mitigation targets necessarily concern maximum mean state change, understanding impacts and developing adaptation strategies will be largely contingent on how climate variability responds to increasing anthropogenic perturbations. Thus far Earth system modeling efforts have primarily focused on projected mean state changes and the sensitivity of specific modes of climate variability, such as the El Niño-Southern Oscillation. However, our knowledge of forced changes in the overall spectrum of climate variability and higher order statistics is relatively limited. Here we present a new 100-member large ensemble of climate change projections conducted with the Community Earth System Model version 2 to examine the sensitivity of internal climate fluctuations to greenhouse warming. Our unprecedented simulations reveal that changes in variability, considered broadly in terms of probability, distribution, amplitude, frequency, phasing, and patterns, are ubiquitous and span a wide range of physical and ecosystem variables across many spatial and temporal scales. Greenhouse warming will in particular alter variance spectra of Earth system variables that are characterized by non-Gaussian probability distributions, such as rainfall, primary production, or fire occurrence. Our modeling results have important implications for climate adaptation efforts, resource management, seasonal predictions, and for assessing potential stressors for terrestrial and marine ecosystems.

Human Rights Due Diligence

Climate change has been described as one of the greatest threats to people and the planet. Its impacts affect virtually the entire spectrum of internationally recognised human rights as well as the environment in and of itself. In relation to human rights, there is a growing consensus that companies should exercise human rights due diligence in order to identify and prevent their actual and potential adverse impacts. However, the relevance and implications of the concept of the due diligence have not yet fully been analysed in relation to climate change. In this paper, we explore the concept of risk-based due diligence, which builds on the concept of human rights due diligence but extends it to other areas such as the environment. Through a review of recent regulatory developments as well as case-law and other grievances, we analyse the three facets of risk-based due diligence for climate change—prevention, mitigation and remediation. We consider both the short term as well as the longer-term human rights and environmental implications of companies’ climate-related impacts, as well as those resulting from the company’s contributions to the green transition. We argue that risk-based due diligence offers an under-explored but important dual function: providing the operational means through which companies can identify and address the climate-related human rights and environmental impacts with which they may be involved, whilst also taking into consideration the human rights implications of their climate mitigation strategies and contributions to the just transition.

AbstractA large body of research has explored opportunities to mitigate climate change in agricultural systems; however, less research has explored opportunities across the food system. Here we expand the existing research with a review of potential mitigation opportunities across the entire food system, including in pre-production, production, processing, transport, consumption and loss and waste. We detail and synthesize recent research on the topic, and explore the applicability of different climate mitigation strategies in varying country contexts with different economic and agricultural systems. Further, we highlight some potential adaptation co-benefits of food system mitigation strategies and explore the potential implications of such strategies on food systems as a whole. We suggest that a food systems research approach is greatly needed to capture such potential synergies, and highlight key areas of additional research including a greater focus on low- and middle-income countries in particular. We conclude by discussing the policy and finance opportunities needed to advance mitigation strategies in food systems.

AbstractGlobal biodiversity is projected to further decline under a wide range of future socio-economic development pathways, even in sustainability oriented scenarios. This raises the question how biodiversity can be put on a path to recovery, the core challenge for the CBD post-2020 global biodiversity framework. We designed two contrasting, ambitious global conservation strategies, ‘Half Earth’ (HE) and ‘Sharing the Planet’ (SP), and evaluated their ability to restore terrestrial and freshwater biodiversity and to provide ecosystem services while also mitigating climate change and ensuring food security. We applied the integrated assessment framework IMAGE with the GLOBIO biodiversity model, using the ‘Middle of the Road’ Shared Socio-economic Pathway (SSP2) with its projected human population growth as baseline.We found that both conservation strategies result in a reduction in the loss of biodiversity and ecosystem services globally, but without additional measures to achieve effective climate mitigation they will be insufficient to restore biodiversity. The HE strategy performs better for terrestrial biodiversity protection (biodiversity intactness (MSA), Red List Index, geometric mean abundance) in currently still natural regions, reflecting global conservation priorities. The SP strategy yields more improvements for biodiversity in human-used areas, aquatic biodiversity and for regulating ecosystem services (pest control, pollination, erosion control), reflecting regional priorities. However, ‘conservation only’ scenarios show a considerable increase in food security risks (especially in Sub-Saharan Africa) compared to the baseline and limited reduction of global temperature increase. Only when conservation strategies are combined with climate change mitigation efforts and additional actions especially in the agricultural and energy system into a portfolio of ‘integrated sustainability measures’, both conservation strategies result in restoring biodiversity to current values or even some improvement, while keeping global warming below two degrees and keeping food security risks below baseline. Minimizing food wastes and reducing consumption of animal products will be crucial.

Streambeds are among the important components of stream ecosystems and support several critical ecosystem services such as transformation of organic matter and nutrients and provide habitat for aquatic organisms. Increasing anthropogenic influence introduces multiple stressors to the stream networks resulting in pollution of streambeds, which in turn, could have detrimental effects on overall stream ecosystem health. However, there are gaps in the current understanding of the impacts of streambed pollution and the mitigation strategies lack holistic approach. In this review, we first present a global inventory to highlight the status of streambed pollution around the globe. Next, we synthesize the state-of-art knowledge of conventional and emerging forms of contaminants, their overall impacts on stream ecosystem functions, and finally present future directions to comprehend the problem of streambed pollution. We highlight that fine sediments and plastics (found especially in urban streambeds) are among the major physical pollutants of streambed pollution and the chemical pollutants generally comprise of hydrophobic compounds including various legacy contaminants such as polychlorinated biphenyl (PCB), dichlorodiphenyltrichloroethane (DDT), a wide range of pesticides and a variety of heavy metals. Further, in recent years, highly polar and hydrophilic emerging contaminants such as micro-plastics, pharmaceutical waste and personal care products have been identified in rivers around the world. We stress that the impacts of streambed pollution have been largely studied with discipline-driven perspectives amongst which the ecological impacts have received a lot of attention in the past. To present a comprehensive outlook, this review also synthesizes the hydrological, geomorphological and biochemical impacts of different forms of streambed pollutants. In the end, we endorse the positive and negative aspects of the current impact assessment methodologies and also highlight various physical, chemical and biological remediation measures that could be applied to alleviate streambed pollution.

This paper provides one of the few assessments of the economic implications of climate change policies in the important region of Eastern Europe and post-Soviet states. We use an integrated assessment model to evaluate the consequences of implementing climate policies consistent with the targets proposed by the Major Economies Forum by mid-century. We decompose the economic impacts in terms of domestic abatement costs, of oil trading and of international emission permit trading for a variety of scenarios, and show that these could be substantial for this region. The results point towards innovation and economic diversification as key complementary measures to be implemented in preparation of climate mitigation strategies.

Purpose This paper aims to clarify the relationship between climate change, its negative impacts on human health and its role in catalysing public engagement for climate policies. It aims to increase public support for climate-mitigation strategies by showing the medical case for negative climate-induced health impacts, the economic burden it entails and the public response to climate change that may be expected when health frames are used. Design/methodology/approach The paper reviews medical, economic and behavioural studies focusing on climate-induced health impacts, its economic costs and its potential for catalysing public engagement for climate policy. Findings The paper provides empirical insights about the various direct and indirect effects of climate change on human health which includes both physical impacts (infectious and non-infectious diseases) and non-physical impacts (mental disorders and reduced labour productivity). Extreme events such as storms, floods and droughts further seriously affect the health of many people, as they restrict food production and water supply. Economic damage costs of climate-induced health impacts are underestimated. Together, natural science, medical and economic studies warrant giving more attention to health in public debates on climate change. The more so as evidence of behavioural studies suggests that the use of health frames reinforces public concern for climate issues. Originality/value This paper argues that climate-induced health impacts and their economic costs should be given more serious attention in discussions about climate-mitigation strategies. They can augment public support for climate policy.

<p>This thesis investigates the Takeo community’s perception of climate change risks and their response strategies. It examines risks occurring in the regions and their impacts on the community. The thesis also explores how the perception of risks frames the community’s adaptation and mitigation strategies as well as how those perceptions influence climate change policies. This research draws on a range of risk perception theories. Employing a qualitative approach, this study uses semi-structured interviews, document analysis and participant observation as its research methods. Interviews were conducted individually with agricultural practitioners, mothers, community leaders, a local government officer and a government official from the Ministry of Environment.   The thesis found that the Takeo’s community has a good perception of the issue and its impacts on their community. Droughts are the major concern for the majority of respondents, because these have become more severe and have the most direct impact on farmers’ lives, livelihoods and food security. The study reflects the view maintained by past and current theory, that individual perceptions of risks vary, and the perception of risk is influenced by media and peers. This study adds that farmers’ direct experience of climate change affects their consideration of such risks as an issue of great personal concern.   Perception of climate change influences the community’s responses. Farmers employ a wide range of adaptation strategies such as increasing water storage and improving agricultural techniques. However, adaptation approaches are not enough to provide a long-term solution to the fast changing climate, because the community has limited knowledge of adaptation strategies, resources, and limited support from the government. The community, thus, needs to improve its water management by building more dams and sufficient irrigation that can store enough water for consumption and agriculture in the prolonged dry season. The government should provide more support and services to poor rural communities that rely on agriculture.</p>
