Consumers’ knowledge about climate change 总被引：2，自引：2，他引：0
Several studies have unveiled various misconceptions about climate change that the public holds, for instance, confusion about climate change and ozone depletion. However, so far, there has been no uniform and standardized way to measure climate-related knowledge, which complicates comparisons between different countries or samples. To develop an extensive knowledge scale, we therefore examined the Swiss public??s understanding of climate change in a mail survey and related this scale to attitudes toward climate change. We thereby aimed to consider a broad range of climate-related knowledge, namely physical knowledge about CO2 and the greenhouse effect, knowledge about climate change and its causes, knowledge about the expected consequences of climate change, and action-related knowledge. The questionnaire included items of different degrees of difficulty, ranging from knowledge that is covered by newspapers to experts?? knowledge. Our findings indicate that people still hold several misconceptions, although people??s knowledge related to CO2 seems to have increased compared to previous studies. Of all knowledge subscales, knowledge about climate change and causes was most strongly related to attitudes toward climate change. 相似文献

This introduction to a special issue of Climatic Change argues that it is timely and welcome to intensify historical research into climate change and climate as factors of history. This is also already an ongoing trend in many disciplines. The article identifies two main strands in historical work on climate change, both multi-disciplinary: one that looks for it as a driver of historical change in human societies, the other that analyzes the intellectual and scientific roots of the climate system and its changes. In presenting the five papers in this special issue the introduction argues that it is becoming increasingly important to also situate “historicizing climate change” within the history of thought and practice in wider fields, as a matter of intellectual, political, and social history and theory. The five papers all serve as examples of intellectual, political, and social responses to climate-related phenomena and their consequences (ones that have manifested themselves relatively recently and are predominantly attributable to anthropogenic climate change). The historicizing work that these papers perform lies in the analysis of issues that are rising in societies related to climate change in its modern anthropogenic version. The history here is not so much about past climates, although climate change itself is always directly or indirectly present in the story, but rather about history as the social space where encounters take place and where new conditions for humans and societies and their companion species and their life worlds in natures and environments are unfolding and negotiated. With climate change as a growing phenomenon historicizing climate change in this version will become increasingly relevant. 相似文献

Although climate change is an urgent problem, behavioural and policy responses have not yet been sufficient to either reduce the volume of greenhouse gas emissions or adapt to a disrupted climate system. Significant efforts have been made to raise public awareness of the dangers posed by climate change. One reason why these efforts might not be sufficient is rooted in people’s need to feel efficacy to solve complex problems; the belief that climate change is unstoppable might thwart action even among the concerned. This paper tests for the effect of fatalistic beliefs on behavioural change and willingness to pay to address climate change using two cross-national surveys representing over 50,000 people in 48 nations.
Key policy insights
The perception that climate change poses a risk or danger increases the likelihood of behavioural change and willingness to pay to address climate change.
The belief that climate change is unstoppable reduces the behavioural and policy response to climate change and moderates risk perception.
Communicators and policy leaders should carefully frame climate change as a difficult, yet solvable, problem to circumvent fatalistic beliefs.

Human systems will have to adapt to climate change. Understanding of the magnitude of the adaptation challenge at a global scale, however, is incomplete, constrained by a limited understanding of if and how adaptation is taking place. Here we develop and apply a methodology to track and characterize adaptation action; we apply these methods to the peer-reviewed, English-language literature. Our results challenge a number of common assumptions about adaptation while supporting others: (1) Considerable research on adaptation has been conducted yet the majority of studies report on vulnerability assessments and natural systems (or intentions to act), not adaptation actions. (2) Climate change is rarely the sole or primary motivator for adaptation action. (3) Extreme events are important adaptation stimuli across regions. (4) Proactive adaptation is the most commonly reported adaptive response, particularly in developed nations. (5) Adaptation action is more frequently reported in developed nations, with middle income countries underrepresented and low-income regions dominated by reports from a small number of countries. (6) There is limited reporting on adaptations being developed to take advantage of climate change or focusing on women, elderly, or children. 相似文献

Social marketing is the systematic application of marketing concepts and techniques to achieve specific behavioural goals relevant to the social good. Social marketing approaches are becoming increasingly popular among governmental and non-governmental actors seeking to engage the public on climate change. The effectiveness of social marketing in achieving specific behavioural goals is empirically well-supported. However, in the first systematic critique of social marketing as a strategy for engaging the public on climate change, we present evidence that social marketing alone is insufficient to build support for the more ambitious policy changes and interventions that constitute a proportional response to climate change. In some circumstances, social marketing approaches may even be counterproductive. We describe some alternative approaches for engaging the public, which may provide governmental and non-governmental actors with additional or preferable tools for promoting public engagement with climate change. Given the scale of the challenge, it seems critical that those seeking to engage the public are equipped with the most effective strategies available - a goal that this paper seeks to contribute to. We conclude that acknowledging the limitations of social marketing - and exploring alternative methods of engaging the public - is an urgent task for climate change communication researchers and practitioners. 相似文献

This paper presents a review of the methodology applied for generating the regional climate change scenarios utilized in important National Documents of Mexico, such as the Fourth National Communication to the United Nations Framework Convention on Climate Change, the Fourth National Report to the Convention on Biological Diversity and The Economics of Climate Change in Mexico. It is shown that these regional climate change scenarios, which are one of the main inputs to support the assessments presented in these documents, are an example of the erroneous use of statistical downscaling techniques. The arguments presented here imply that the work based on such scenarios should be revised and therefore, these documents are inadequate for supporting national decision- making. 相似文献

Feeling affected by climate change related disasters has the potential to mobilize belief in climate change, concern about the issue, and support for mitigation policies – even when accounting for the effects of physically living through a disaster. In this study we use a two-wave survey design where respondents in the United States were interviewed before and after Hurricane Florence to better understand who feels affected by such disasters. First, we find that being worried about climate change increases the feeling of being affected by the hurricane among those who regularly discuss climate change. Second, we find that those who are high in perspective taking are more likely to feel affected. However, those who are high in empathic concern, but feel obligated to help victims of disasters, are less likely to feel affected. This suggests that hurricanes may cause a collapse of compassion, where those who are especially sensitive to the suffering of others down-regulate their emotional response to costly disasters. 相似文献

With poverty alleviation and sustainable development as key imperatives for a developing economy like India, what drives the resource-constrained state governments to prioritize actions that address climate change impacts? We examine this question and argue that without access to additional earmarked financial resources, climate action would get overshadowed by developmental priorities and effective mainstreaming might not be possible. A systematic literature review was carried out to draw insights from the current state of implementation of adaptation projects, programmes and schemes at the subnational levels, along with barriers to mainstreaming climate change adaptation. The findings from a literature review were supplemented with lessons emerging from the implementation of India’s National Adaptation Fund on Climate Change (NAFCC). The results of this study underscore the scheme’s relevance.Key policy insights
Experience with NAFCC implementation reveals that states require sustained ‘handholding’ in terms of financial, technical and capacity support until climate change issues are fully understood and embedded in the policy landscape.
Domestic sources of finance are critically important in the absence of predictable and adequate adaptation finance from international sources.
The dedicated window for climate finance fosters a spirit of competitive federalism among states and encourages enhanced climate action.
Enhanced budgetary allocation to NAFCC to strengthen the state-level adaptation response and create capacity to mainstream climate change concerns in state planning frames, is urgently needed.

Abstract The UNFCCC has set the objective of preventing ‘dangerous’ climate change. The concept of climate change being ‘dangerous’ has generally been interpreted to mean that there are thresholds below which the planet is ‘safe’ and above which it is in danger. This creates the fiction that danger can be averted, when that is largely a matter of perspective. Policies based on fictions can succeed if the major parties are willing to go along with them, but this is not the case at present. It is dangerous to try and motivate the public on the basis of a patent fiction, since that obscures policy-critical ignorance and may ultimately create more brittle political frameworks. An alternative to maintaining the fiction is to acknowledge at the outset the arbitrary and conditional nature of any specific choice or definition of what is ‘dangerous’ climate change and what is not. Although our choices are somewhat arbitrary, they can be informed by a range of analytical perspectives, and the decisions we reach have real import. In this setting, we need a way to provide order to (arbitrary) choices that draws on what is known, but still acknowledges the conditional nature of the choices. It is argued here that the aesthetic realm may be suited to this need. 相似文献

The world is generally becoming less violent, but the debate on climate change raises the specter of a new source of instability and conflict. In this field, the policy debate is running well ahead of its academic foundation—and sometimes even contrary to the best evidence. Although comparative research on security implications of climate change is rapidly expanding, major gaps in knowledge still exist. Taken together, extant studies provide mostly inconclusive insights, with contradictory or weak demonstrated effects of climate variability and change on armed conflict. This article reviews the empirical literature on short-term climate/environmental change and intrastate conflict, with special attention to possible insecurity consequences of precipitation and temperature anomalies and weather-related natural disasters. Based on this assessment, it outlines priorities for future research in this area. 相似文献

Although existing economic research is informative with regard to the importance of including potential ‘catastrophic’ climate change impacts in the analysis of GHG mitigation benefits, the generic and abstract form of the ‘catastrophe’ implemented has led to a lack of specific policy implications. This article provides an important starting point for a discussion of how to improve economic modelling of potential large-scale impacts of climate change. It considers how the term ‘abrupt climate change’ has been used in the scientific literature to describe changes in the climate system and carefully reviews the characteristics of the events that have been discussed in this context. The findings are compared to the way in which the economic literature has modelled potential economic and human welfare impacts of these ‘catastrophic’ events. In general, the economics literature is found to have modelled such impacts in a uniform way that fails to account for differences in relevant end points and timescales. The result is policy recommendations based on events that do not resemble those of concern. Better treatment of these events in integrated assessment modelling would help ensure that future research efforts can serve as meaningful policy input. 相似文献

The capelin is a small pelagic fish that performs long distance migrations. It is a key species in the Barents Sea ecosystem
and its distribution is highly climate dependent. Here we use an individual based model to investigate consequences of global
warming on capelin distribution and population dynamics. The model relies on input on physics and plankton from a biophysical
ocean model, and the entire life cycle of capelin including spawning of eggs, larval drift and adult movement is simulated.
Spawning day and adult movement strategies are adapted by a genetic algorithm. Spawning has to take place in designated near-shore
spawning areas. The output generated by the model is capelin migration/distribution and population dynamics. We present simulations
with present day climate and a future climate scenario. For the present climate the model evolves a spatial distribution resembling
typical spatial dynamics of capelin with the coasts of Northern Norway and Murman as the main spawning areas. For the climate
change simulation, the capelin is predicted to shift spawning eastwards and also utilize new spawning areas along Novaya Zemlya.
There is also a shift in the adult distribution towards the north eastern part of the Barents Sea and earlier spawning associated
with the warming. 相似文献

Adapting California’s water management to climate change 总被引：1，自引：0，他引：1
California faces significant water management challenges from climate change, affecting water supply, aquatic ecosystems,
and flood risks. Fortunately, the state also possesses adaptation tools and institutional capabilities that can limit vulnerability
to changing conditions. Water supply managers have begun using underground storage, water transfers, conservation, recycling,
and desalination to meet changing demands. These same tools are promising options for responding to a wide range of climate
changes. Likewise, many staples of flood management—including reservoir operations, levees, bypasses, insurance, and land-use
regulation—are available for the challenges of increased floods. Yet actions are also needed to improve response capacity.
For water supply, a central issue is the management of the Sacramento-San Joaquin Delta, where new conveyance, habitat investments,
and regulations are needed to sustain water supplies and protect endangered fish species. For flood management, among the
least-examined aspects of water management with climate change, needed reforms include forward-looking reservoir operation
planning and floodplain mapping, less restrictive rules for raising local funds, and improved public information on flood
risks. For water quality, an urgent priority is better science. Although local agencies are central players, adaptation will
require strong-willed state leadership to shape institutions, incentives, and regulations capable of responding to change.
Federal cooperation often will be essential. 相似文献

The 2m temperature (T2m) and precipitation from five regional climate models (RCMs), which participated in the ENSEMBLES project and were integrated at a 25-km horizontal resolution, are compared with observed climatological data from 13 stations located in the Croatian coastal zone. The twentieth century climate was simulated by forcing RCMs with identical boundary conditions from the ERA-40 reanalysis and the ECHAM5/MPI-OM global climate model (GCM); climate change in the twenty-first century is based on the A1B scenario and assessed from the GCM-forced RCMs’ integrations. When forced by ERA-40, most RCMs exhibit cold bias in winter which contributes to an overestimation of the T2m annual cycle amplitude and the errors in interannual variability are in all RCMs smaller than those in the climatological mean. All models underestimate observed warming trends in the period 1951–2010. The largest precipitation biases coincide with locations/seasons with small observed amounts but large precipitation amounts near high orography are relatively well reproduced. When forced by the same GCM all RCMs exhibit a warming in the cold half-year and a cooling (or weak warming) in the warm period, implying a strong impact of GCM boundary forcing. The future eastern Adriatic climate is characterised by a warming, up to +5 °C towards the end of the twenty-first century; for precipitation, no clear signal is evident in the first half of the twenty-first century, but a reduction in precipitation during summer prevails in the second half. It is argued that land-sea contrast and complex coastal configuration of the Croatian coast, i.e. multitude of island and well indented coastline, have a major impact on small-scale variability. Orography plays important role only at small number of coastal locations. We hypothesise that the parameterisations related to land surface processes and soil hydrology have relatively stronger impact on variability than orography at those locations that include a relatively large fraction of land (most coastal stations), but affecting less strongly locations at the Adriatic islands. 相似文献

The topics of climate change and of what to do about it have been the subject of discussion for over two decades. Much of
the focus has been on mitigating greenhouse gas emissions to reduce the rate and magnitude of changes. Adapting to the impacts
of those changes has received much less attention. In recent years, the development assistance community has recognized that
climate change poses a stress on economic and social development in poor countries and has turned its attention to addressing
climate stress. The US Agency for International Development developed a methodology of working with stakeholders to identify
sources of climate related vulnerability and approaches to reducing that vulnerability. The methodology was developed iteratively
with several pilot studies looking at vulnerability and adaptation in different sectors and settings. 相似文献

Global climate change and variability and its influence on Alpine climate — concepts and observations 总被引：1，自引：0，他引：1

Summary The paper discusses annual to decadal climate variability and change in the European Alps by utilizing the procedure of synoptic downscaling, i.e. it investigates the influence of global to continental scale synoptic structures and processes on the regional climate of the Alps. The European Alps lie to the southeast and under the right exit zone of the southwest-northeast oriented axis of the polar front jet over the North Atlantic ocean, in a transition zone between the Azores high and Icelandic low, between oceanic and continental and between Mediterranean and North Atlantic climates. Together with complex topographically induced phenomena like lee cyclogenesis, orographic precipitation, strong downslope winds and thermotopographical circulation systems, this transitional position makes climate studies in the Alps even more interesting. Only a minor correlation can be observed between global climate variability and Alpine climate. In contrast, the Alpine climate is strongly related to processes over the North Atlantic ocean and its sea ice system (e.g. it has a high correlation with the North Atlantic Oscillation and the dynamics and position of the Icelandic low), an area with a rather low climate prediction potential.Since the early 1970's (or just after the Great Salinity Anomaly in the North Atlantic Ocean) the intensification of the wintertime westerly jet over the North Atlantic area led to a noticeable northwest-southeast mass transport in the exit area of the jet over Central Europe, leading to pressure and temperature rises and an increase in the amount of precipitation. There is a question over whether this phenomenon is a consequence of natural climate variability or the beginning of an anthropogenic climate change.With 16 Figures 相似文献

The dominant assumption in economic models of climate policy remains that adaptation will be implemented in an optimal manner. There are, however, several reasons why optimal levels of adaptation may not be attainable. This paper investigates the effects of suboptimal levels of adaptation caused by different types of adaptation restrictions, on the composition and level of climate change costs and on welfare. We find that especially restrictions to the effectiveness of adaptation at more extreme levels of climate change can be very harmful. Furthermore we show that the potential of mitigation to offset suboptimal adaptation varies from being essential in case adaptation becomes ineffective at higher temperature increases, to being largely ineffective in case of short-term inaction. However, in all cases the short-term recommendation is to increase mitigation levels slightly above what is normally recommended, and to keep mitigation policies flexible enough to be able to respond when adaptation restrictions become more prominent. It is clear that by reducing adaptation restrictions, in combination with adjusting the optimal level of mitigation may keep the costs of adaptation restrictions limited, and thus generally it is very harmful to ignore existing restrictions on adaptation when devising (efficient) climate policies. 相似文献

The language of transformational change is increasingly applied to climate policy, and particularly in climate finance. Transformational change in this context is used with respect to low-carbon development futures, with the emphasis on mitigation and GHG metrics. But, for many developing countries, climate policy is embedded in a larger context of sustainable development objectives, defined through a national process. Viewed thus, there is a potential tension between mitigation-focused transformation and nationally driven sustainable development. We explore this tension in the context of operationalizing the Green Climate Fund (GCF), which has to deal with the fundamental tension between country ownership and transformational change. In relation to climate finance, acceptance of diverse interpretations of transformation are essential conditions for avoiding risk of transformational change becoming a conditionality on development. We further draw lessons from climate governance and the development aid literature. The article examines how in the case of both the Clean Development Mechanism and Nationally Appropriate Mitigation Actions, there has been limited success in achieving both development objectives and ‘nationally appropriate’ mitigation. The development aid literature points to process-based approaches as a possible alternative, but there are limitations to this approach.
Policy relevance
The concept of transformational change has gained prominence in climate finance. The conundrum facing the GCF is that it seeks to support transformational change in the climate realm, in a context where countries may have competing priorities. Balancing or even transcending this tension is a fundamental design challenge for the GCF. A primary focus on mitigation, particularly if metrics of performance are tied exclusively to GHG reduction, raise concerns about diluting ownership by recipient countries and evokes concerns of conditionality or worse. The literature on development assistance has explored options notably conditions on process and adequate capacity, and suggests that there are no short cuts to building domestic ownership. Actors on climate change need to avoid the risk that transformational change is perceived as, and becomes, an imposed condition. The risk that transformation change, operationalized in the context of unequal power relations, becomes an imposition on development, needs to be avoided. 相似文献
