Cool dudes: The denial of climate change among conservative white males in the United States

We examine whether conservative white males are more likely than are other adults in the U.S. general public to endorse climate change denial. We draw theoretical and analytical guidance from the identity-protective cognition thesis explaining the white male effect and from recent political psychology scholarship documenting the heightened system-justification tendencies of political conservatives. We utilize public opinion data from ten Gallup surveys from 2001 to 2010, focusing specifically on five indicators of climate change denial. We find that conservative white males are significantly more likely than are other Americans to endorse denialist views on all five items, and that these differences are even greater for those conservative white males who self-report understanding global warming very well. Furthermore, the results of our multivariate logistic regression models reveal that the conservative white male effect remains significant when controlling for the direct effects of political ideology, race, and gender as well as the effects of nine control variables. We thus conclude that the unique views of conservative white males contribute significantly to the high level of climate change denial in the United States.     

Lights, camera … action? Altered attitudes and behaviour in response to the climate change film The Age of Stupid

The film The Age of Stupid depicts the world in 2055 devastated by climate change, combining this with documentary footage which illustrates many facets of the problems of climate change and fossil-fuel dependency. This study investigates the effects of the film on UK viewers’ attitudes and behaviour through a three-stage survey. Analysis of changes in attitudes focussed particularly on respondents’ concern about climate change, motivation to act, fear about the potential for catastrophe, beliefs about responsibility for action, and sense of agency. The film increased concern about climate change, motivation to act, and viewers’ sense of agency, although these effects had not persisted 10-14 weeks after seeing it. It was also successful in promoting some mitigation actions and behavioural change, although respondents reported barriers to further action, such as limited options for improving home energy efficiency among those in rented accommodation. However, filmgoers were atypical of the general public in that they exhibited very high levels of concern about climate change, knowledge about how to reduce their carbon emissions, and contact with organisations campaigning about climate change, before they saw the film. The paper considers how these factors may have enabled viewers to respond to the film as they did, as well as policy implications for those seeking to develop effective climate change communications.     

Public engagement with carbon and climate change: To what extent is the public ‘carbon capable’?

The relevance of climate change for society seems indisputable: scientific evidence points to a significant human contribution in causing climate change, and impacts which will increasingly affect human welfare. In order to meet national and international greenhouse gas (GHG) emissions reduction targets, there is an urgent need to understand and enable societal engagement in mitigation. Yet recent research indicates that this involvement is currently limited: although awareness of climate change is widespread, understanding and behavioral engagement are far lower. Proposals for mitigative ‘personal carbon budgets’ imply a need for public understanding of the causes and consequences of carbon emissions, as well as the ability to reduce emissions. However, little has been done to consider the situated meanings of carbon and energy in everyday life and decisions. This paper builds on the concept of ‘carbon capability’, a term which captures the contextual meanings associated with carbon and individuals’ abilities and motivations to reduce emissions. We present empirical findings from a UK survey of public engagement with climate change and carbon capability, focusing on both individual and institutional dimensions. These findings highlight the diverse public understandings about ‘carbon’, encompassing technical, social, and moral discourses; and provide further evidence for the environmental value-action gap in relation to adoption of low-carbon lifestyles. Implications of these findings for promoting public engagement with climate change and carbon capability are discussed.

Rethinking graduated citizenship: Contemporary public housing in Singapore

The ways in which citizenship and housing are implicated in states’ global city aspirations demonstrate significant path dependency and local contingency. This paper serves to broaden the literature that has been dominated by the Western neoliberal context. First, I argue that The Pinnacle@Duxton – a one-of-a-kind public housing project in Singapore – represents the developmental state’s attempt to graduate its homogeneous public housing landscape, providing for and subsidizing the aspirations of a segment of its increasingly affluent middle class to buy into the ideology of the global city. Second, I show how the graduation of public housing coupled with the exaggerated demand for such exclusive projects validates consumer preference pricing in contemporary public housing. This results in a geographical graduation of citizenship, where the bulk of the population is relegated to lesser options on the edges on the island, unable to fulfil their aspirations for global living. In so doing, I make two contributions to extant literature on housing and citizenship in the global city. One, graduating citizenship is not always a case of states realigning their relationship with their citizens to fit the terms of the market. Two, the denial of citizenship to the global city does not always manifest in terms of substantive rights. Appreciating the unique histories and ideologies underpinning housing policies in global cities is instrumental if the variegated meanings of global cities and the citizenships within are to be elucidated.     

In the name of Development: Power,profit and the datafication of the global South

We examine the current ‘datafication’ process underway in low- and middle-income countries (LMICs), and the power shifts it is creating in the field of international development. The use of new communications and database technologies in LMICs is generating ‘big data’ (for example from the use of mobile phones, mobile-based financial services and the internet) which is collected and processed by corporations. When shared, these data are also becoming a potentially valuable resource for development research and policy. With these new sources of data, new power structures are emerging within the field of development. We identify two trends in particular, illustrating them with examples: first, the empowerment of public–private partnerships around datafication in LMICs and the consequently growing agency of corporations as development actors. Second, the way commercially generated big data is becoming the foundation for country-level ‘data doubles’, i.e. digital representations of social phenomena and/or territories that are created in parallel with, and sometimes in lieu of, national data and statistics. We explore the resulting shift from legibility (Scott, 1998) to visibility, and the implications of seeing development interventions as a byproduct of larger-scale processes of informational capitalism.     

The role and limits of strategic framing for promoting sustainable consumption and policy

Strategic issue framing is widely regarded as an effective communication strategy to alter public opinion and citizens’ policy support. However, it is unclear to what extent strategic framing can increase support for ambitious demand-side actions and policies that make the cost of mitigation perceptible in citizens’ everyday lives. Taking an exploratory approach, we conducted qualitative interviews and a comparative framing experiment with 9,750 survey respondents from China, Germany, and the United States. We analyzed strategic issue framing effects in two areas known to be key for increasing the sustainability of consumption: meat/fish consumption, and fossil-fuel car usage. Employing both classical linear regressions and advanced Bayesian sparse estimations, we show that in all three countries widespread arguments in favor of reduced meat/fish consumption and car use are unlikely to substantially alter citizens’ concern, willingness to pay, behavioral intentions and policy support for demand-side action. Our findings suggest that in the absence of a broader behavioral change campaign, strategic issue framing alone is unlikely to be effective in changing entrenched attitudes and behaviors. On its own, it is also unlikely to substantially increase public support for demand-side policies to reduce consumption. More careful research is needed to help policymakers understand the role and limits of different strategic framing techniques.
