Rapid adaptation is necessary to maintain, let alone expand, access to reliable, safe drinking water in the face of climate change. Existing research focuses largely on the role, priorities, and incentives of local managers to pursue adaptation strategies while mostly neglecting the role of the broader public, despite the strong public support required to fund and implement many climate adaptation plans. In this paper, we interrogate the relationship between personal experiences of household water supply impacts from extreme weather events and hazard exposure with individual concern about future supply reliability among a statewide representative sample of California households. We find that more than one-third of Californians report experiencing impacts of climate change on their household water supplies and show that these reported impacts differently influence residents’ concern about future water supply reliability, depending on the type of event experienced. In contrast, residents’ concern about future water supplies is not significantly associated with hazard exposure. These findings emphasize the importance of local managers’ attending to not only how climate change is projected to affect their water resources, but how, and whether, residents perceive these risks. The critical role of personal experience in increasing concern highlights that post-extreme events with water supply impacts may offer a critical window to advance solutions. Managers should not assume, however, that all extreme events will promote concern in the same way or to the same degree. [ABSTRACT FROM AUTHOR]

The Arctic region is one of the most exposed to the global climate change. Russia accounts for more than a half of the whole Arctic territory and population and allocates most of the economic activity of the region. From the Soviet time till now, the Arctic region also accounts for a substantial share of Russia’s wealth. The article analyzes often ambiguous knowledge on climate change implications for the long-term economic development of the Russian Arctic. Based on the review of the key policy documents issued in Russia and ongoing and planned development programs, the study aspires to contribute more clarity on Russia’s standing in the Arctic region. We aim to analyze the convergence of Russian climate and Arctic policies boosting the synergies between each other. The paper discovers, among other issues, the climate change adaptation priorities in policy areas aimed at minimizing net costs of climate change. While policies rhetorically aim at contributing to resilient and sustainable growth in the Russian North, they remain under-developed in accounting for multiple climate-related risks. Our analysis suggests that a comprehensive framework of Arctic policy measures should be centered around climate change as a core factor underlying the future of the region and should encompass two main policy dimensions: (a) strengthening the knowledge base on climate change, the adjunct risks, and emerging opportunities in the region and (b) developing the system for climate change risk management and resilience building ensuring that regional diversity and climatic and socioeconomic features of various locations are taken into serious account.

With high certainty, extreme weather events will intensify in their impact within the next 10 years due to climate change-induced increases in hazard probability of occurrence and simultaneous increases in socio-economic vulnerability. Data from previous mega-disasters show that losses from disruptions of critical services surpass the value of direct damages in the exposed areas because critical infrastructures [CI] are increasingly (inter-) dependent. Local events may have global impacts. Systemic criticality, which describes the relevance of a critical infrastructure due to its positioning within the system, needs to be addressed to reduce the likelihood of cascading effects. This paper presents novel approaches to operationalise and assess systemic criticality. Firstly, the paper introduces systemic cascade potential as a measurement of systemic criticality. It takes the relevance of a sector and the relevance of its interdependencies into account to generate a relative value of systemic importance for a CI sector. Secondly, an exemplary sectoral assessment of the road network allows reflecting the spatial manifestation of the first level of cascading effects. It analyses the impact of traffic interruptions on the accessibility of critical facilities to point out the systemically most critical segments of the municipal road network. To further operationalise the spatial dimension of criticality, a normative assertion determining the worthiness of protection of system components is required. A nationwide spatial flood protection plan incorporates this aspect in Germany for the first time. Its formal approval process was initiated in February 2020. [ABSTRACT FROM AUTHOR]

Water extraction is fundamentally altering many of the world's rivers, floodplains and wetlands, while drying trends intensify competition for water resources. Climate change is challenging integrated water resource management policies that aim to balance human and environmental water needs. This paper explores the challenges of managing natural resources in a regime of climate change. It examines Australia's Murray-Darling Basin, where national water law requires a Basin Plan based on best available science. However, proactively responding to climate risks is institutionally and politically complex, even though understanding of the Basin's hydro-climate system has improved. Despite decades of research consistently warning of a drying climate, the Basin Plan relied on historical hydrological data to determine future water resource availability. The paper uses the heuristic of the science-policy interface to examine why there were no significant adjustments to account for climate change. This analysis finds that the science-policy interface is highly politicised, with different risk cultures in the scientific, governmental, political and commercial sectors constraining adaptation planning. These constraints need to be overcome because the changing nature of the Anthropocene's rivers means adaptive policy and institutional frameworks are needed that can navigate the complexities, uncertainties and indeterminacies of a changing climate.

There is increasing concern that climate change poses an existential risk to humanity. Understanding these worst-case scenarios is essential for good risk management. However, our knowledge of the causal pathways through which climate change could cause societal collapse is underdeveloped. This paper aims to identify and structure an empirical evidence base of the climate change, food insecurity and societal collapse pathway. We first review the societal collapse and existential risk literature and define a set of determinants of societal collapse. We develop an original methodology, using these determinants as societal collapse proxies, to identify an empirical evidence base of climate change, food insecurity and societal collapse in contemporary society and then structure it using a novel-format causal loop diagram (CLD) defined at global scale and national granularity. The resulting evidence base varies in temporal and spatial distribution of study and in the type of data-driven methods used. The resulting CLD documents the spread of the evidence base, using line thickness and colour to depict density and type of data-driven method respectively. It enables exploration of how the effects of climate change may undermine agricultural systems and disrupt food supply, which can lead to economic shocks, socio-political instability as well as starvation, migration and conflict. Suggestions are made for future work that could build on this paper to further develop our qualitative understanding of, and quantitative complex systems modelling capabilities for analysing, the causal pathways between climate change and societal collapse.

Cities in the USA and around the world have begun to take an active role in responding to climate change. A central requirement for effective urban climate strategies is the capacity to understand and measure how the climate is changing, the physical, environmental, and social impacts of the changes, and whether adaptation and resiliency policies and programs put in place in response are working. The objective of this paper is to review and assess how urban climate change and resiliency efforts can be measured and to define what might serve as meaningful indicator and monitoring protocols. The New York City Panel on Climate Change (NPCC) is used as a case study along with a reviews of the emerging literature of urban climate change indicators to analyze the requirements and processes needed for a successful urban climate resiliency indicator and monitoring (I and M) system. In the paper, the basic requirements of a proposed Urban Climate Resilience Indicators and Monitoring System are presented. A specific illustration of an I and M system for tracking the urban heat island highlights challenges as well as potential solutions embedded within such systems. Discussions how these protocols can be translated to other locales and settings, as well as the relationship to the US National Climate Assessment indicator process, are presented.

This article is part of a Special Issue on "National Indicators of Climate Changes, Impacts, and Vulnerability" edited by Anthony C. Janetos and Melissa A. Kenney Introduction Climate assessment efforts in the USA are a legally required and important process to share the state of knowledge about status and projected trends of climate changes and impacts and are used to support risk management decisions and policies (Jacobs et al. [11]). Contributions to this special issue The first paper in this special issue is I A framework for national climate indicators i (Kenney et al. [19]). In the first topical paper, I Toward an integrated system of climate change and human health indicators: a conceptual framework i (Liu et al. in preparation), the human health implications of climate change were explored to identify indicators. In I Indicators of climate change in agricultural systems i (Hatfield et al. [10]), the authors develop a conceptual framework that links the climate system to crop and livestock productivity as well as the impacts of land on other grassland and forest systems.

Previous studies have projected a significant role for bioenergy in decarbonizing the global economy and helping realize international climate goals such as limiting global average warming to 2 ˚C or 1.5 ˚C. However, with substantial variability in bioenergy results and significant concerns about potential environmental and social implications, greater transparency and dedicated assessment of the underlying modeling and results and more detailed understanding of the potential role of bioenergy are needed. Stanford University's Energy Modeling Forum (EMF) initiated a 33rd study (EMF-33) to explore the viability of large-scale bioenergy as part of a comprehensive climate management strategy. This special issue presents the papers of the EMF-33 study—a multi-year inter-model comparison project designed to understand and assess global, long-run biomass supply and bioenergy deployment potentials and related uncertainties. Using a novel scenario design with independent biomass supply and bioenergy demand protocols, EMF-33 separately elucidates and explores the modeling of biomass feedstock supplies and bioenergy technologies and their deployment—revealing, comparing, and assessing the modeling that is suggesting that bioenergy could be a key climate containment strategy. This introduction provides an overview of the EMF-33 study design and the overview, thematic, and individual modeling team papers and types of insights that make up this special issue. By providing enhanced transparency and new detailed insights, we hope to inform policy dialogue about the potential role of bioenergy and facilitate new research. [ABSTRACT FROM AUTHOR]

This paper explores the potential role of bioenergy coupled to carbon dioxide (CO2) capture and storage (BECCS) in long-term global scenarios. We first validate past insights regarding the potential use of BECCS in achieving climate goals based on results from 11 integrated assessment models (IAMs) that participated in the 33rd study of the Stanford Energy Modeling Forum (EMF-33). As found in previous studies, our results consistently project large-scale cost-effective BECCS deployment. However, we also find a strong synergistic nexus between CCS and biomass, with bioenergy the preferred fuel for CCS as the climate constraint increases. Specifically, the share of bioenergy that is coupled to CCS technologies increases since CCS effectively enhances the emissions mitigation capacity of bioenergy. For the models that include BECCS technologies across multiple sectors, there is significant deployment in conjunction with liquid fuel or hydrogen production to decarbonize the transportation sector. Using a wide set of scenarios, we find carbon removal to be crucial to achieving goals consistent with 1.5 °C warming. However, we find earlier BECCS deployment but not necessarily greater use in the long-term since ultimately deployment is limited by economic competition with other carbon-free technologies, especially in the electricity sector, by land-use competition (especially with food) affecting biomass feedstock availability and price, and by carbon storage limitations. The extent of BECCS deployment varies based on model assumptions, with BECCS deployment competitive in some models below carbon prices of 100 US$/tCO2. Without carbon removal, 2 °C is infeasible in some models, while those that solve find similar levels of bioenergy use but substantially greater mitigation costs. Overall, the paper provides needed transparency regarding BECCS' role, and results highlight a strong nexus between bioenergy and CCS, and a large reliance on not-yet-commercial BECCS technologies for achieving climate goals.

This paper assesses the potential role of the implementation of the best available technologies to reduce the economic consequences of outdoor air pollution in the coming decades. The paper focuses on market impacts related with additional health expenditures, changes in labour productivity and crop yield losses and also presents results on non-market costs, i.e. welfare losses from avoided premature deaths. The results show that technological improvements can potentially reduce concentrations of air pollutants to levels compatible with the WHO guidelines in most countries. However, technology measures can only reduce part of the economic costs relative with the market impacts. While those are efficient in reducing the direct costs of air pollution, there are still large indirect costs associated with current and remaining pollution levels. Policies that aim directly at avoiding economic impacts need to be implemented to further reduce air pollution damages, especially in the regions where technologies are not sufficient to reduce concentrations or where economic consequences persist despite reduced concentration levels.

This paper assesses the options that developing countries have in ensuring food security in an environment where key climate parameters are changing rapidly. Based on a case study of Lesotho, the paper utilizes the Global Climate Model ensemble to determine future precipitation and temperature projections using data from Climate Explorer. The results indicate that in Lesotho, maximum temperature is likely to continue to increase. Coupled with a significant increase in precipitation under both Representative Concentration Pathway (RCP) 4.5 (p = 0.0008) and RCP 8.5 (p = 0.0001) scenarios and a significant increase of evaporation under the two scenarios for RCP 4.5 (p = 0.0008) and RCP 8.5 (p = 0.0103), the country's preparedness for hazards arising from climate change is rendered uncertain. Despite this reality, we suggest that uncertainty could be reduced by reinforcing existing innovative measures that could improve the productive capacity of subsistence farmers, so that they meet their own food requirements, while preventing further environmental deterioration. While some measures will be based on the intensification of government-led social support mechanisms, others will depend on the support rendered to "tried and tested" traditional practices such as machobane and fato-fato, which have a long tradition in the country. However, on their own, these measures are insufficient to cope with rapidly changing climatic conditions, unless they are coupled with national research development initiatives, improved early warning systems, and enhancement of environmental monitoring capabilities, the implementation of which requires careful land use planning.

Adaptation needs in high mountain communities are increasingly well documented, yet most efforts to address these needs continue to befall mountain people who have contributed little to the problem of climate change. This situation represents a contravention of accepted norms of climate justice and calls attention to the need for better understanding of prospects for externally resourced adaptation initiatives in high mountain areas. In response, this paper examines the architecture of formal adaptation support mechanisms organized through the United Nations Framework Convention on Climate Change (UNFCCC) and how such mechanisms might help to meet adaptation needs in high mountain communities. It outlines key global adaptation initiatives organized through the UNFCCC, clarifies idealized linkages between these global adaptation initiatives and meeting local adaptation needs, and evaluates actual progress in connecting such support with discrete adaptation needs in the upper Manaslu region of Nepal. The paper then critically examines observed shortcomings in matching adaptation support organized through the UNFCCC with local adaptation needs, including complications stemming from the bureaucratic nature of formal adaptation support mechanisms, the intervening role of the state in delivering aid, and the ways in which these complexities intersect with the specific socio-cultural contexts of mountain communities. It concludes by highlighting several prospects for increasing the quantity and quality of adaptation support to mountain communities. These opportunities are considered alongside several salient concerns about formal adaptation support mechanisms in an effort to provide a well-rounded assessment of the prospects for planned adaptations in high mountain communities.

This paper explores stakeholder perspectives on the drought discourse in the UK, where climate change is predicted to increase drought risk. This study took a co-productive, mixed-methods approach to investigate drought risk communication issues through repeated engagements with local advisory groups in seven catchments across Britain and a national stakeholder competency group. These data were enriched by in-depth interviews with 17 statutory and non-statutory stakeholders working in a variety of capacities from water supply to habitat management. Codes were divided into contextual factors (cultural or drought specific factors) and individual factors (individual attributes relating to the person receiving the communication or factors within the control of communicators). The paper considers the implications of these contextual and personal factors for approaches to, and the framing of, drought risk communication (DRC). We conclude by proposing a framework for thinking about DRC in maritime climates where drought risk may not be readily perceived by some publics. This framework explores the role of heuristics in risk perception, and proposes a way of conceptualising publics that may more readily engage with DRC. In proposing the framework, we seek to stimulate new ways of thinking about DRC. [ABSTRACT FROM AUTHOR]

The tangible progress to address climatic change remains painfully slow. As a result, practices to deliberately manipulate the Earth's carbon and energy cycles to counteract climate change have gained traction and they are increasingly incorporated into mainstream debate. This paper examines one of the less documented examples of climate geoengineering, namely the creation of 'super low carbon cows'. Driven by the public's desire for a low carbon pint of milk or beef burger, I show how a combination of bioengineering, technological fixes and management practices have resulted in, and are informing, everyday changes to the way in which animals are bred, cared for and eaten—and in turn, how it affects the food that we consume. Thus, the role of the cow within the Anthropocene now extends from meat machine and sentient being to climate change saviour. I seek to show that super low carbon cows represent part of a wider climate 'responsibilisation' in which business interests and corporate storytelling are governing and enacting everyday mundane practices of climate engineering as part of the corporate carbon economy. Yet, as with other climate 'fixes', this paper shows that the super low carbon cow provides, at best, an imperfect correction. Critical gaps in the evidence of the efficiency of the solutions being advanced remain whilst manipulating an animal to be more climate friendly evokes unease when considering the wider sustainability and ethical impacts. Perhaps most critically, reliance on climate engineering to provide cheap and easy ways to control our climate fails to question, far less address, the ever-increasing demand, production and wastage of food. It also potentially undermines the already weak political will for other essential and more radical responses to climate change. In doing so, I contrast the extensive efforts to change the everyday behaviours of a cow with the limited attempts to meaningfully challenge the everyday practices, consumption lifestyles and dietary choices of the general public.

There is now no doubt that current global production-consumption-disposal systems are threatening the fundamental conditions of existence on this planet. In response, the pressing need for total system transformation has gained civic and political traction, feeding into long-standing debates and interventions that are aimed at recalibrating prevailing economic and social practices. One such debate and intervention is that of the circular economy (CE). Here, advocates argue that current linear resource and energy use systems must be reconfigured into loops of re-use, repair, refurbishment, and recycling, displacing primary production and lessening greenhouse gas emissions in the process. This agenda has potentially profound implications for aspects of daily social practices. Yet, to date, little attention has been paid (politically and in research) to how the CE does and will interact with everyday habits, norms, and meanings. In response, this paper explores some of the conceptual assumptions underlying the CE 'consumer'. It argues that mainstream CE debates are underscored by an impoverished view of our relationships with complex material cultures, which in turn is creating barriers to transformation. Drawing on empirical research into responses to the CE in the UK and the Netherlands, this paper contrasts the challenges of inciting consumers to take up new, resource-efficient business models in contexts of hyper-consumerism, with a more hopeful 'small story' of overt, small-scale circular spaces, that nevertheless embed the CE and its underlying impetuses more clearly into the everyday.

Greenhouse gas removal (GGR) techniques appear to offer hopes of balancing limited global carbon budgets by removing substantial amounts of greenhouse gases from the atmosphere later this century. This hope rests on an assumption that GGR will largely supplement emissions reduction. The paper reviews the expectations of GGR implied by integrated assessment modelling, categorizes ways in which delivery or promises of GGR might instead deter or delay emissions reduction, and offers a preliminary estimate of the possible extent of three such forms of 'mitigation deterrence'. Type 1 is described as 'substitution and failure': an estimated 50–229 Gt-C (or 70% of expected GGR) may substitute for emissions otherwise reduced, yet may not be delivered (as a result of political, economic or technical shortcomings, or subsequent leakage or diversion of captured carbon into short-term utilization). Type 2, described as 'rebounds', encompasses rebounds, multipliers, and side-effects, such as those arising from land-use change, or use of captured CO2 in enhanced oil recovery. A partial estimate suggests that this could add 25–134 Gt-C to unabated emissions. Type 3, described as 'imagined offsets', is estimated to affect 17–27% of the emissions reductions required, reducing abatement by a further 182–297 Gt-C. The combined effect of these unanticipated net additions of CO2 to the atmosphere is equivalent to an additional temperature rise of up to 1.4 °C. The paper concludes that such a risk merits further deeper analysis and serious consideration of measures which might limit the occurrence and extent of mitigation deterrence. [ABSTRACT FROM AUTHOR]

In 2013, the Arctic Athabaskan Council representing the Arctic Athabaskan peoples filed a petition to the Inter-American Commission on Human Rights. The Council sought relief for violations of their rights resulting from rapid Arctic warming and melting caused by emissions of black carbon by Canada. The aim of the paper is to show legal complaints and arguments of a particular indigenous people, Arctic Athabaskans—arguments intended to enforce Canada's obligation to reduce or eliminate black carbon emissions, which negatively affect numerous rights of indigenous Athabaskans. Additionally, the article will point to the new legal developments and potential success of those arguments and litigation itself. The article analyses issues at the intersection of human rights, indigenous peoples and climate change. The concluding remarks attempt to answer the research questions and offer some reflections on the potential to protect indigenous peoples' rights offered by this type of advocacy strategy and, more specifically, the petition in particular. The research method adopted is that of legal-institutional analysis as well as content analysis of relevant literature (analysis of the discourse). This paper moves forward existing climate litigation literature which focuses on human rights. As Osofsky and Peel (2018) highlight, human rights-based climate litigation is a new development in the field, and this paper expands it further. [ABSTRACT FROM AUTHOR]

In this paper, a systematic literature review was conducted to synthesize understanding on farmers' perception on climate change. Farmers' perception of climate change is conceptualized as comprising of three dimensions—first, as farmers' "awareness"; second, "conceptual understanding"; and third, the "experience" of climate change. The review included 162 papers published during the period January 2000 to July 2019. The highest number of studies was conducted in Africa, followed by Asia. A large majority of farmers report being aware of climate change. However, only a few studies elicit the difference between climate variability and climate change from farmers. A negligible number of studies attempt to identify the role of agricultural activities in greenhouse gas emissions and climate change. Furthermore, authors compare farmers' perception with meteorological evidence, which is more aligned in terms of change in "temperature" rather than "precipitation." The insights from the review provide guidance on conceptualization and operationalization of the variable "farmers' perception of climate change" for future studies. [ABSTRACT FROM AUTHOR]

The cranberry, a commodity of social, cultural, and economic importance to New England, is under threat due to climatic change in this region of the United States. Yet, previous research reveals that cranberry growers have mixed attitudes about the anthropogenic roots of climate change, with many being skeptical. Building on the researchers' analysis of the personal and ecological conditions that affect climate change attitudes among cranberry growers, this paper examines the effect that key actors in the growers' social networks have on those attitudes. Through statistical analysis of survey data and content analysis of two important cranberry newsletters, the paper finds that cranberry growers' perceived importance of two key cranberry growing institutions, the "sociopolitically focused" Cape Cod Cranberry Growers' Association and the "technically focused" University of Massachusetts Cranberry Station, as well as connections to other cranberry growers, is associated in nuanced ways with growers' climate change attitudes. Drawing on the sociological theory of "social capital," the paper examines how these social ties to key actors/institutions may result in greater threat perception or worry about climate change. It then considers how "green ties," if harnessed and supported by these important actors in the cranberry grower network, might significantly mitigate climate change in the future.

Effective strategies to learn about and engage with climate change play an important role in addressing this challenge. There is a growing recognition that education needs to change in order to address climate change, yet the question remains "how?" How does one engage young people with a topic that is perceived as abstract, distant, and complex, and which at the same time is contributing to growing feelings of sadness, hopelessness, and anxiety among them? In this paper, I argue that although the important contributions that the arts and humanities can make to this challenge are widely discussed, they remain an untapped or underutilized potential. I then present a novel framework and demonstrate its use in schools. Findings from a high school in Portugal point to the central place that art can play in climate change education and engagement more general, with avenues for greater depth of learning and transformative potential. The paper provides guidance for involvement in, with, and through art and makes suggestions to create links between disciplines to support meaning-making, create new images, and metaphors and bring in a wider solution space for climate change. Going beyond the stereotypes of art as communication and mainstream climate change education, it offers teachers, facilitators, and researchers a wider portfolio for climate change engagement that makes use of the multiple potentials of the arts.

Climate change loss and damage (L&D) presents an existential threat to the Fiji Islands. This case study examines how rural Indo-Fijian sugarcane farming communities face challenges in minimising, averting, and addressing L&D from cyclones. In-depth semi-structured interviews (n = 68) were conducted with 40 sugarcane farmers in two Indo-Fijian sugarcane communities, Barotu and Toko settlements in Western Viti Levu, Fiji, and with 28 key stakeholders from government ministries, academia, and climate change response services. Despite implementing climate change adaptation measures, Fiji’s sugar industry has faced devastating L&D from frequent and severe cyclones. Much of the climate change L&D to crops, property, and income was irreversible and unavoidable. Non-economic loss and damage (NELD) was found insurmountable in both field sites, including the loss of homes and places of worship, cascading and flow-on effects as well as the heightening of uncertainty, fear, and trauma. Evidence suggests that L&D, including NELD, is highly context specific, and UNFCCC’s broad NELD categories do not fully capture L&D at the local level. The systematic documentation of L&D within vulnerable communities would improve understanding of L&D, including NELD, and assist to facilitate the mobilisation of immediate support and action to address L&D in countries that lack the capacities to respond independently. This paper recommends crucial policy interventions such as livelihood diversification, integration of disaster risk reduction and climate change adaptation, land tenure policy reforms, and the operationalisation of the Santiago Network for Loss and Damage.

Negative emission technologies (NETs) for the removal and long-term storage of atmospheric carbon are increasingly essential to meeting climate targets. In order to meet the need for large-scale and durable removals with low land and water footprints, scientists and engineers are exploring systems that directly capture CO2 from the air and store it underground or under the seabed. Often, the social acceptability of these systems is presumed unlikely given the sheer complexity of their components, governance arrangements, perceived advantages and disadvantages, and the different moral and value positions at play. This paper explores public perceptions of a proposed direct air carbon capture with storage (DACCS) system that includes renewable-powered direct air capture of CO2 paired with sub-seafloor injection and CO2 storage as rock via mineralization). Using a representative survey of n=2120 US and Canadian residents located near to a proposed system pilot, analysis reveals two very different profiles of perceivers, pro and con. Rejection of the system as a whole is driven by concern regarding storage or below-sea components, physical risks (e.g., leakage), and belief that such a system constitutes a moral hazard, enabling continued fossil fuel dependence. Conversely, those who support such a system perceive it as economically, climatically, and ethically beneficial now and for future generations, express a strong sense of climate severity and urgency, and see themselves as responsible for natural systems. We close with cautions as to the social licence for negative emission technologies, the implications of these findings, and the fragility of hope as these possibilities unfold.

Pacific Island countries are vulnerable to climate variability and change. Developing strategies for adaptation and planning processes in the Pacific requires new knowledge and updated information on climate science. In this paper, we review key climatic processes and drivers that operate in the Pacific, how they may change in the future and what the impact of these changes might be. In particular, our emphasis is on the two major atmospheric circulation patterns, namely the Hadley and Walker circulations. We also examine climatic features such as the South Pacific Convergence Zone and Intertropical Convergence Zone, as well as factors that modulate natural climate variability on different timescales. It is anticipated that our review of the main climate processes and drivers that operate in the Pacific, as well as how these processes and drivers are likely to change in the future under anthropogenic global warming, can help relevant national agencies (such as Meteorological Services and National Disaster Management Offices) clearly communicate new information to sector-specific stakeholders and the wider community through awareness raising.

Climate change is likely to have significant impacts on the forestry sector in New Zealand. However, an understanding of how forest growers are reducing their risks from climate change impacts is still in its infancy. This paper applies the protection motivation theory to identify socio-psychological factors influencing forest growers' adaptation to climate change. This study presents the survey results from 60 forest growers who have the combined responsibility for managing more than 70% of New Zealand's plantation forests. We investigated whether their perceived response efficacy, self-efficacy and their understanding of response costs are predictors of their protective or adaptive measures. Based on our survey, risk reduction and risk spreading are the two types of protective measure frequently reported by the respondents to deal with climate risks. Consistent with the protection motivation theory, our findings show that respondents who are more likely to implement protective or adaptive measures if they perceive the threat severity to be high have high self-efficacy and resource efficacy, and exhibit low maladaptive responses such as evading and postponing behaviours. Furthermore, our findings also suggest that there is a low self-efficacy belief with strong maladaptive behaviour among the respondents that negatively influence their motivation to implement adaptation measures. This result provides guidance to policy makers, researchers and forest companies on how to make climate change adaptation efforts effective by considering the forest growers motivation to adapt to climate change.

Based on the government's historical records and personal documents of the pre-modern Chosŏn Dynasty, this paper examines the socio-economic impacts in Korea in response to climatic variability from 1809 until 1819 that may have been influenced to some degree by the eruption of the "unknown volcano" (1809) and the Tambora eruption (1815). In the early 1800s, when volcanic eruptions occurred successively, the Korean Peninsula experienced a temporal precipitation variation—drought, abundant rainfall, and normalcy—twice. The precipitation variation in this period had a heavy impact on the yields of rice, major crop on the peninsula. In the phase of drought in 1809 and extreme climatic anomalies in 1814, the country suffered record poor harvests, and in the abundant rainfall phase in 1810 and 1816–1817, it had bumper crops. For this reason, 1816–1817 were the halcyon years for Korea, unlike the case of Europe and the northeastern USA which suffered from extreme climatic anomalies in those years. This case of the Korean Peninsula indicates that the climate change and natural disasters of the 1810s were influenced by not only of the single event of the Tambora eruption but of the successive eruptions of volcanoes in the 7 years from 1809 to 1815, which also affected other areas on the globe for 11 years (1809–1819).

This paper deals with the earliest meteorological observations in Florence after the Medici Network (1654–1670), i.e., from mid-seventeenth to mid-eighteenth century, and puts them in the context of the history of meteorology in Florence. After the gap caused by the Inquisition, observations started again in the eighteenth century, made by Cipriano Antonino Targioni (1728–1748), Giovanni Targioni-Tozzetti (1737–1740), Pietro Gaetano Grifoni (1751–1766), Leonardo Ximenes (1752), and Luca Martini (1756–1772). The first two records were lost, and this paper considers those by Grifoni and Ximenes. The latter is affected by severe bias; the former is of good quality and has been recovered and analyzed. Both the observers made only one reading a day and the metadata are scarce. The paper discusses several issues: the conversion from the apparent solar time to the Central Europe Time; the transformation from a single reading to a daily average; the identification of the thermometric liquid and the scale; the test made with the snow benchmark; the comparison with the contemporary series in Bologna. The comparison of the reconstructed series with other periods, i.e., 1654–1670, 1881–1910, 1961–1990, and 1991–2017, reveals that in mid-eighteenth century the temperature reached the lowest levels, especially in summer, and showed a sudden warming in the most recent decades.

An important and under-quantified facet of the risks associated with human-induced climate change emerges through extreme weather. In this paper, we present an initial attempt to quantify recent costs related to extreme weather due to human interference in the climate system, focusing on economic costs arising from droughts and floods in New Zealand during the decade 2007–2017. We calculate these using previously collected information about the damages and losses associated with past floods and droughts, and estimates of the "fraction of attributable risk" that characterizes each event. The estimates we obtain are not comprehensive, and almost certainly represent an underestimate of the full economic costs of climate change, notably chronic costs associated with long-term trends. However, the paper shows the potential for developing a new stream of information that is relevant to a range of stakeholders and research communities, especially those with an interest in the aggregation of the costs of climate change or the identification of specific costs associated with potential liability.

Long instrumental records are fundamental to study climate changes, but their reliability and quality have to be checked before any statistical research. Moreover, when metadata are used to solve some problems, data interpretation may change and require further work to refine the series. A thorough revision of the three-century precipitation series in Padua (1713–2018) shows that the results of previous analyses were affected by serious biases. This paper clarifies key features concerning early instruments, exposure, relocation and observational protocols. The daily analysis pointed out a number of problems, bias, irregular sampling and underestimations that have passed unobserved so far. A comparison with the parallel series of Bologna and Venice made it possible to distinguish bias from the climate signal or to reconstruct missing data. The instrumental threshold was recognized to be fundamental to determine the frequency of precipitation, but less important with respect to its amount. This paper provides a methodological example to test the goodness of long instrumental series, in particular to identify problems related to metadata and observations, which is the preliminary step to perform a sound correction and obtain a reliable series. It also includes the set of original raw data, transformed into modern units. [ABSTRACT FROM AUTHOR]

Developing country case studies have thus far been under-represented in conceptual models attempting to theorize energy transitions. This paper explores the role of climate finance in the process of Madagascar's planned transition to renewable energy sources as envisioned in the country's New Energy Policy in order to demonstrate the different experience in developing countries when compared to hegemonic transition narratives. Drawing upon qualitative interviews with energy finance providers and focus groups in recently electrified rural communities, this paper reveals that Madagascar's transition is dependent on the financial resources mobilized by the government's technical and financial partners. Climate finance emerges as a critical lever to implement environmental legislation. The interview findings were correlated with census data to evaluate how current financing strategies are directly connected to energy justice issues, namely the equality in access to affordable and clean energy. Through an analysis of projected energy finance flows and key financiers' financing strategies, this paper exposes a shift from grant-based climate finance to financial instruments with clear return profiles, such as concessional loans and private capital, and finds that the choice of financial instrument impacts the provision of complementary social services in rural electrification schemes. Grants are linked to higher investments into complementary social services, while private financiers focus on innovation and scale. Purely private financed electrification projects were found to negatively impact social cohesion by increasing the inequality in access to energy. This study concludes that if only commercially viable energy projects were to be financed going forward, up to 19 million Madagascans might be excluded from future electrification efforts. Consequently, this paper urges researchers to consider social justice implications when evaluating climate finance strategies. [ABSTRACT FROM AUTHOR]

Despite the economic importance of the tourism sector and its close relationship to the environment and climate, substantial gaps remain in the investigation of climate change (CC) impacts on tourism. Unlike the increasing body of literature focusing on the variation in the climatic suitability of tourism destinations, this paper focuses on the impacts of CC on the provision of natural resources affecting the attractiveness of destinations. More specifically, the paper provides an economic measurement of climate-induced environmental changes on the coast of Mallorca (Spain), one of the Mediterranean's leading sun-and-beach destinations. A choice experiment is used to elicit the willingness to pay (WTP) of tourists for the introduction of policies aimed at reducing three climate-induced environmental changes. The estimated results show the positive WTP of tourists to reduce CC impacts and provide evidence of preference heterogeneity among individuals with different socioeconomic and travel characteristics.

The retreat of urban populations as an adaptation strategy has the potential to protect people, businesses, and infrastructure from the severe impacts of climate change. However, it can also lead to the unjust dislocation of the urban poor whose contributions to climate change are negligible but whose exposure to climatic risk is high. These groups of people also have little say in the decision-making about whether to retreat, when and how, thus raising concerns about equity and justice. In this paper, I examine the policy and practice of managed retreat and its environmental justice dimensions in Manila (Philippines) and Lagos (Nigeria) from 2010 to 2018. Expert interviews, focus group discussions, and policy documents were collected and analyzed for both cities. Findings reveal a complex picture of contradictions. In Lagos, retreat was stated in climate change policy but in practice only the urban poor were forcibly removed from waterfront areas and in their place new urban development projects are being constructed. In Manila, retreat was not mentioned in policy but evidence indicates informal settlers and national government offices were the target of planned retreat. Unlike Lagos, the urban poor in Manila were offered a mortgaged pathway to homeownership outside the city. However, the lack of livelihood opportunities in relocation sites engendered a cycle of retreat and return. This study further discusses how climatic uncertainties, property values, government distrust, utopian imaginaries, and environmental injustices served as barriers to managed retreat in both cities. The paper concludes with a call for an environmentally and socially just approach to retreat. It argues that the rights of the urban poor to the city must be taken into consideration even under complex climatic and socio-ecological disruptions. [ABSTRACT FROM AUTHOR]

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]

With recent growth in funding and research on "resilience building", interest in climate services has risen dramatically. Included in this trend is an increased emphasis on the use of climate and weather information for a range of purposes across multiple scales. Non-governmental organisations (NGOs) and other non-state actors across Africa have responded accordingly, and are increasingly acting as brokers, and sometimes producers, of climate services as part of their activities. Drawing on research from Burkina Faso and Ethiopia as part of the Building Resilience and Adaptation to Climate Extremes and Disasters (BRACED) programme, this paper critically examines the evolving climate services landscape and raises questions about what the future holds for climate services in sub-Saharan Africa. We ask two questions: How have national climate services in these countries evolved since the early 2000s when they first came to prominence? And how have NGO contributions to these services evolved over time? Our findings highlight a considerable evolution in the aims and capacities of climate service systems over this period. NGOs have contributed to this progress on multiple fronts, but we note that important opportunities for innovation remain. We also raise concerns about how the current financing and governance models may influence priority setting and the sustainability of "projectised" services. Accordingly, we call for a better understanding how power and politics shape the development and deployment of climate services. This paper provides insight on the evolving landscape of climate services, actors involved in its provision and implications for the future. [ABSTRACT FROM AUTHOR]

Climate information and agro-advisory services are crucial in helping smallholder farmers and pastoralists in East Africa manage climate-related risks and adapt to climate change. However, significant gaps exist in provision of climate information that effectively addresses the needs of farmers and pastoralists. Most farmers and pastoralists, therefore, rely on indigenous knowledge (IK), where local indicators and experiences are used to observe and forecast weather conditions. While IK-based forecasting is inbuilt and established in many communities in East Africa, coordinated research and systematic documentation of IK for weather forecasting, including accuracy and reliability of IK is largely lacking. This paper documents and synthesizes existing IK for weather forecasting in East Africa using case studies from Ethiopia, Tanzania, and Uganda. The results show that farmers and pastoralists use a combination of meteorological, biological, and astrological indicators to forecast local weather conditions. IK weather forecasting is, therefore, crucial in supporting efforts to improve access to climate information in East Africa, especially in resource-poor and vulnerable communities. The paper draws valuable lessons on how farmers and pastoralists in East Africa use IK weather forecasts for making crop and livestock production decisions and demonstrates that the trust and willingness to apply scientific forecasts by farmers and pastoralists is likely to increase when integrated with IK. Therefore, a systematic documentation of IK, and a framework for integrating IK and scientific weather forecasting from national meteorological agencies can improve accuracy, uptake, and use of weather forecasts.

This paper describes five sets of regions intended for use in summarizing extreme weather over Earth’s land areas from a climate perspective. The sets differ in terms of their target size: ∼10 Mm2, ∼5 Mm2, ∼2 Mm2, ∼0.5 Mm2, and ∼0.1 Mm2 (where 1 Mm2= 1 million km2). The regions are based on political/economic divisions, and hence are intended to be primarily aligned with geographical domains of decision-making and disaster response rather than other factors such as climatological homogeneity. This paper describes the method for defining these sets of regions; provides the final definitions of the regions; and performs some comparisons across the five sets and other available regional definitions with global land coverage, according to climatological and non-climatological properties.

Climate change is increasingly acknowledged as a fundamental risk to the stability of the financial system. The linkage between residential mortgage lending and local heatwave projections has hitherto received little attention in the climate finance discourse despite recognition of the detrimental effects of extreme heat on economic output measures. Through economic, demographic and other channels, future climate conditions can affect the housing market and, thus, the residential mortgage market. Moreover, the potential for contagion is high considering US residential mortgages’ key role in financial cycles and cross-border effects. First, our paper furthers conceptual and empirical understandings of the nexus between future extreme heat and lenders’ credit risk. Second, for the contiguous US states, we show that interest rates are higher and loan terms are shorter in areas forecast to experience a larger increase in the number of hot days over the coming decades after controlling for a range of factors. Rate spreads are higher still in areas where the number of hot days is projected to be extreme. It is lending from non-banks, rather than banks, that appears sensitive to the changing climate.

Integrated assessment models are tools largely used to investigate the benefit of reducing polluting emissions and limiting the anthropogenic mean temperature rise. However, they have been often criticized for their underlying assumptions, often leading to low levels of abatement. Countries and regions that are generally the actors in these models are usually depicted as having standard concave utility functions in consumption. This, however, disregards a potentially important aspect of environmental negotiations, namely its distributive implications. The present paper tries to fill this gap assuming that countries/regions have Fehr and Schmidt (The Quarterly Journal of Economics 114(3):817–868, 1999) (F&S) utility functions, specifically tailored for including inequality aversion. By adopting the RICE model, we compare its standard results with the ones obtained introducing F&S utility functions, showing that, under optimal cooperation, the level of temperature rise is lower in the last scenario. In particular, the peak temperature, reached in 2155 under standard assumptions and one or two decades later under F&S preferences with, respectively, heterogeneous and homogeneous F&S inequality aversion parameters (α and β), is of 2.86 ∘C in the former scenario and of 2.65 ∘C and 2.67 ∘C in the latter two. Furthermore, it is shown that potentially stable coalitions are easier to be achieved when F&S preferences are assumed. However, potentially stable coalitions are far from reaching environmental targets close to limiting the mean temperature rise below 2 ∘C despite the adoption of F&S utility functions. The 2 ∘C target is almost achieved in all scenarios when the payoffs in the F&S utility function are given by the per-capita consumption rather than utility of consumption, with F&S preferences and heterogeneous F&S inequality aversion parameters leading to a peak temperature rise of 2.04 ∘C.

Climate models, by accurately forecasting future weather events, can be a critical tool in developing countermeasures to reduce crop loss and decrease adverse effects on animal husbandry and fishing. In this paper, we investigate the efficacy of various regional versions of the climate models, RCMs, and the commonly available weather datasets in Kenya in predicting extreme weather patterns in northern and western Kenya. We identified two models that may be used to predict flood risks and potential drought events in these regions. The combination of artificial neural networks (ANNs) and weather station data was the most effective in predicting future drought occurrences in Turkana and Wajir with accuracies ranging from 78 to 90%. In the case of flood forecasting, isolation forests models using weather station data had the best overall performance. The above models and datasets may form the basis of an early warning system for use in Kenya’s agricultural sector. [ABSTRACT FROM AUTHOR]

Climate change is widely recognized as a major risk to societies and natural ecosystems but the high end of the risk, i.e., where risks become existential, is poorly framed, defined, and analyzed in the scientific literature. This gap is at odds with the fundamental relevance of existential risks for humanity, and it also limits the ability of scientific communities to engage with emerging debates and narratives about the existential dimension of climate change that have recently gained considerable traction. This paper intends to address this gap by scoping and defining existential risks related to climate change. We first review the context of existential risks and climate change, drawing on research in fields on global catastrophic risks, and on key risks and the so-called Reasons for Concern in the reports of the Intergovernmental Panel on Climate Change. We also consider how existential risks are framed in the civil society climate movement as well as what can be learned in this respect from the COVID-19 crisis. To better frame existential risks in the context of climate change, we propose to define them as those risks that threaten the existence of a subject, where this subject can be an individual person, a community, or nation state or humanity. The threat to their existence is defined by two levels of severity: conditions that threaten (1) survival and (2) basic human needs. A third level, well-being, is commonly not part of the space of existential risks. Our definition covers a range of different scales, which leads us into further defining six analytical dimensions: physical and social processes involved, systems affected, magnitude, spatial scale, timing, and probability of occurrence. In conclusion, we suggest that a clearer and more precise definition and framing of existential risks of climate change such as we offer here facilitates scientific analysis as well societal and political discourse and action.

Fossil fuel producers develop too many reserves for combustion due to subsidies for upfront development costs. The conventional wisdom is that downward-sloping tax profiles avoid green paradox outcomes by reducing present extraction. This paper shows that accounting for subsidized reserves development can induce green paradox outcomes for downward-sloping income tax profiles. A theoretical model linking reserves development and extraction with climate change damages is developed to explore conditions for the weak and strong green paradox outcomes of higher present extraction and cumulative damages. We find that the weak green paradox arises under higher and flatter income tax profiles. The strong green paradox is an ambiguous outcome without subsidized reserves development. Quantitative examples demonstrate the effect of downward-sloping tax profiles on crude oil extraction and how the strong green paradox arises when delayed emissions are less relevant for damages.

The objective of this paper is to analyze the impact of climate change adaptation strategies on maize productivity of farms focusing on gender differences. To do so, a selection model generalizing the Heckman (1979) approach and the Oaxaca and Blinder decomposition procedure are specified and estimated. The empirical analysis is based on intra-agricultural household data from the 2018 Harmonized Household Living Conditions Survey (EHCVM) of Togo with a total sample of 8622 maize plots disaggregated by seasonThe results reveal that the average maize productivity of men is about 23.5% higher than that of women. Similarly, the average maize productivity of married women is about 28.5% higher than that of unmarried women. This suggests that married men and women have greater adaptive capacity than their counterparts and are also more likely to improve their productivity. The factors that contribute to the performance of married men and women at the expense of their counterparts are secondary education, producer assets, and climate information. We also find that the use of improved seeds, off-season cropping, and a combination of both strategies are the types of coping strategies adopted by men and married women to increase their productivity. These results have implications for the direction of development policies. These development policies can be more targeted at unmarried women. [ABSTRACT FROM AUTHOR]

Investments in climate-change adaptation will have to be made while the extent of climate change is uncertain. However, some important sources of uncertainty will fall over time as more climate data become available. This paper investigates the effect on optimal investment decision-making of learning that reduces uncertainty. It develops a simple real options method to value options that are found in many climate-change adaptation contexts. This method modifies a binomial tree model frequently applied to climate-change adaptation problems, incorporating gradual learning using a Bayesian updating process driven by new observations of extreme events. It is used to investigate the timing, scale, or upgradable design of an adaptation project. Recognition that we might have more or different information in the future makes flexibility valuable. The amount of value added by flexibility and the ways in which flexibility should be exploited depend on how fast we learn about climate change. When learning will occur quickly, the value of the option to delay investment is high. When learning will occur slowly, the value of the option to build a small low-risk project instead of a large high-risk one is high. For intermediate cases, the option to build a small project that can be expanded in the future is high. The approach in this paper can support efficient decision-making on adaptation projects by anticipating that we gradually learn about climate change by the recurrence of extreme events.

The assessment of the impacts of climate change at different levels of global warming helps inform national and international policy discussion around mitigation targets. This paper provides consistent estimates of global and regional impacts and risks at increases in global mean temperature up to 5 °C above pre-industrial levels, for over 30 indicators representing temperature extremes and heatwaves, hydrological change, floods and droughts and proxies for impacts on crop yields. At the global scale, all the impacts that could plausibly be either adverse or beneficial are adverse, and impacts and risks increase with temperature change. For example, the global average chance of a major heatwave increases from 5% in 1981–2010 to 28% at 1.5 °C and 92% at 4 °C, of an agricultural drought increases from 9 to 24% at 1.5 °C and 61% at 4 °C, and of the 50-year return period river flood increases from 2 to 2.4% at 1.5 °C and 5.4% at 4 °C. The chance of a damaging hot spell for maize increases from 5 to 50% at 4 °C, whilst the chance for rice rises from 27 to 46%. There is considerable uncertainty around these central estimates, and impacts and risks vary between regions. Some impacts—for example heatwaves—increase rapidly as temperature increases, whilst others show more linear responses. The paper presents estimates of the risk of impacts exceeding specific targets and demonstrates that these estimates are sensitive to the thresholds used. [ABSTRACT FROM AUTHOR]

This paper comments on the applicability of the global indicators of climate change adaptation policy drivers contained in Berrang-Ford et al. (2014) (Climatic Change, 124(1–2), 441–450. 10.1007/s10584-014-1078-3) for small island developing states (SIDS). SIDS are a globally recognised 'special' case in terms of environment and sustainable development issues as they are disproportionately vulnerable to the impacts of climate change. While acknowledging that the choice of final indicators in the Berrang-Ford et al. (2014) assessment was primarily the function of the results of bivariate analyses with their Adaptation Initiatives Index and that there is no certainty of statistically significant relationships with any measure of adaptation initiatives, this paper proposes the inclusion of a number of predictor variables for a future SIDS-specific quantitative analysis. By doing this, this commentary helps to contribute a more nuanced understanding of potential national adaptation policy drivers in SIDS. [ABSTRACT FROM AUTHOR]

In this final paper, the guest editors identify and discuss ten guidelines emerging from the papers in this Special Issue on Decision-Support Tools for Climate Change Adaptation. The guidelines are arranged under three headings: foundational, design and construction, and supporting sustainability in the long term. Under foundational, we address the need for co-operation with end users of decision-support resources, the contribution these resources can make to the formation of thriving communities of practice, and the match between the different types of decision support and user needs. Under design and construction, we point to the risk that policy settings will change over the multiple years required to build and publish complex decision-support resources, reducing the relevance of the final product. We discuss the need for innovative approaches to ensure visibility, credibility and hence uptake. Developers should be mindful of the requirements, resources and capabilities of potential users at all points in the design and build. We also suggest that decision-support resources may be transferable between sectors and locations, but the motivation should be around achieving excellence, and not just cost savings. Under supporting sustainability in the long term, we stress the need for evaluation and comparative studies of performance, leading to carefully documented updating and improvement of decision-support resources. Finally, in the conclusions, we look to the future. Can decision-support resources evolve successfully to meet the information and guidance requirements of the increasingly sophisticated adaptation practitioner community? [ABSTRACT FROM AUTHOR]

Formal structures for evaluating climate change risk are important components of adaptation decision-making. In this paper, we present an accessible, cost-effective and user-tested climate change risk assessment framework which allows organisations to systematically apply a risk management process aligned with international standards to identify and manage their climate change risks. It is delivered through 'CoastAdapt', a resource supporting climate change adaptation in Australia. This three-tier framework offers four benefits to the adaptation process. First, it allows organisations to identify climate change risks and integrate them with their mainstream risk management process. Second, it makes optimal use of an organisation's limited adaptation resources by taking a tiered approach, so allowing an organisation to start from a low knowledge base using minimal resources and, only if required, then move to more complex and resource-intensive risk assessment processes. Third, it introduces a time-dependent vulnerability rating which recognises the particular characteristics of climate change risks—that they are long term and associated with a considerable degree of uncertainty. Finally, it takes into account business inter-dependencies that can exacerbate impacts but be overlooked in a sector-based impacts evaluation. In this paper, we highlight the appropriate context in which to use each risk assessment tier, explore key technical differences among the three tiers, describe performance testing and present one case study of application. We discuss the benefits of this tiered risk assessment approach in the context of broader adaptation planning. [ABSTRACT FROM AUTHOR]

The potential for transferring and translating existing adaptation to climate change decision-support tools for use in different settings provides both opportunities and challenges to those wanting to support such decisions in or for the targeted community/organisation. The opportunities are related to being able to build on an existing credible and tested tool and its supportive resources and foregoing the costs associated with developing such themselves. The challenges relate to taking advantages of the strengths of an existing tool whilst adapting it and its supportive resources such that they are fit for purpose and accepted within the targeted community/organisation. This paper identifies and explores these opportunities and challenges through those revealed as a result of transferring and translating the UKCIP Adaptation Wizard for use within other parts of the world and in different communities and organisations. Whilst drawing on a number of different examples of where the Wizard has been translated, this paper particularly focuses on the transfer and translation for use in Portugal and in Brazil. General lessons learnt related to transferring adaptation decision-support tools are identified and used to develop a practical framework. The intention is to provide insights that have broader implications for those considering transferring similar adaptation decision-support tools, but also for tool developers who want to see their tools being used more broadly.

Since its release in 2014, the Knowledge Portal for Spatial Adaptation has evolved into the central web portal for climate adaptation in the Netherlands, supporting regional and local adaptation efforts. This paper reflects on how co-production shaped the development of the portal and evaluates its use and the usability of the most frequently accessed tool, the 'Climate Adaptation Atlas'. Analysis of evaluation reports and web-statistics revealed a substantial, diverse and regularly returning group of visitors to the portal. For example, municipalities use the atlas to understand how their municipality can be impacted by climate change to support spatial planning. Using the usability criteria of fit, interplay and interaction, the analysis showed that the atlas fits the needs of creating awareness and integrating climate information with other spatial information. However, the interplay of new climate information with other currently used information varies amongst municipalities. Interactions between scientists and users were found at different stages involving different actors. Based on the development and use of the portal, seven lessons have been derived emphasising the importance of a continuous co-production process with users; a modular setup to acknowledge the diversity in approaches; encouraging users by providing showcases of adaptation initiatives and enabling exchange of information amongst users; the need for political support; the ability and will to act even in case of uncertainty; flexibility in project design to incorporate changes in user needs and the beneficial role of boundary organisations in improving mutual understanding. Through this paper, contributions to the understanding of how adaptation web portals can be developed and improved are made. [ABSTRACT FROM AUTHOR]

Resilience has experienced exponential growth in scholarship and practice over the past several decades. We conduct a meta-analysis of recent review papers on resilience from all relevant fields to distill key themes emanating from both research and practice. These themes reflect prevalent debates, trends and insights from the thousands of underlying papers. The seven themes are: 1) the distinction between resilience as a system trait, process, or outcome; 2) the importance of resilience as a strategy for dealing with uncertainty; 3) a shift from understanding resilience to active resilience building; 4) the incorporation of transformation into resilience; 5) the increasingly normative interpretation of resilience; 6) the growing emphasis on measuring and evaluating resilience; and 7) the mounting critiques of the resilience agenda demanding attention. We discuss each in detail and find that they help explain both why resilience has attracted widespread attention, but also why it is an increasingly contested concept. We offer several steps to engage in productive dialogue across differences in resilience interpretations and conclude that this interand transdisciplinary dialogue is the difficult and necessary work that must be done, if resilience scholarship and practice is to advance in productive ways in the future.

Research on using climate information has often focused on the interaction between users and producers and the technical fit of information for real decision-making. However, due to resource and capacity constraints within both user and producer communities, this approach will not always be feasible or indeed necessary depending on the decisions at hand. These contexts have been relatively under-explored by scholars, and this paper provides an original empirical contribution using three case studies of sub-national governments in India, Kenya and Uganda. In the paper, we analyse how social learning supports changing the usability of climate information and the role of intermediary organisations in these processes. Firstly, the paper shows that intermediaries often choose to build the commitment to project aims rather than using climate information as an entry point to working on climate change, and this allows them to instigate challenging learning processes. Secondly, there are barriers to iterative processes and critical reflection with government stakeholders but these processes can gain traction when built into institutional practices such as formal M&E processes. Lastly, social learning can broaden the framing of climate change from a single sector issue to a multi-sectoral one. We conclude by arguing that bringing together scholarship on social learning with that on the usability of climate information can deepen understanding of the dynamic context in which the information becomes usable. The evidence from the case studies shows that learning processes can alter this context across scales. [ABSTRACT FROM AUTHOR]
