Pennsylvania State University, USADespite overwhelming consensus among scientists about thereality of anthropogenic climate change (Bray, 2010; Oreskes,2004), there remains significant reluctance on the part ofcitizens and politicians to take the action needed to addressit. This resistance has been repeatedly identified in socialresearch (Leiserowitz & Maibach, 2010; Leviston, Leitch,Greenhill, Leonard, & Walker, 2011; Lorenzoni & Pidgeon,2006; McCright & Dunlap, 2011; Reser, Bradley, Glendon,Ellul, & Callaghan, 2012) and is mirrored by the lack of prog-ress made by salient political summits (Rogelj et al., 2010).Perhaps as a response to this, scholarly journals and articlesthat are focused on climate change are growing. Naturalscientists tell us that we know what needs to be done to avertdangerous climate change (IPCC, 2014), and economists tellus that delaying action in the short term will lead to muchgreater costs in the long term (Stern, 2007). Understandingpublic responses to climate change and developing solutionsto catalyse action is a critical challenge for the social sciences,and we propose that the development and elaboration of asocial psychology of climate change would be a cornerstoneof such an approach.We do not make the claim that social psychology has all theanswers but rather that the theories, models and researchmethods of social psychology can provide a powerful arsenalto complement the approaches of other disciplines. Re-searchers have already begun to apply social psychologicaltheory and methods to the issue of climate change, and wehighlight in the following sections examples of the insightsthat have flowed from this. We cannot assume, though, thatour theories and findings will automatically generalise to theclimate change context. As Moser (2010) has noted, thereare unique dimensions to climate change that make it distinctfrom other environmental, risk and health issues: The causesof climate change are invisible to humans, the impacts are dis-tal and it is complex and riddled with uncertainties. Modernurban humans are to some extent insulated from their physicalenvironment, and the lags between the climate and social sys-tems make it difficult for people to understand their role ininfluencing climate.These factors suggest the importance of developing a socialpsychology of climate change, empirically testing, integratingand refining existing theories and models to develop newframeworks. The notion that psychology can play a role inunderstanding and addressing climate change is not a newone. The American Psychological Association’s Task Forceon the interface between psychology and global climatechange comprehensively detailed the ways in which psycho-logical research can help to understand people’s perceptionsof the risks of climate change, the contribution of human be-haviour to climate change, the psychosocial impacts of climatechange, the ways in which people can adapt and cope withclimate change and the psychological barriers that could limitclimate change action (Swim et al., 2009, 2011).It is also not a new idea that social psychology can play animportant role in understanding and addressing environmentalproblems and solutions (Clayton & Brook, 2005). Social psy-chology, specifically, has a long tradition oftheory andresearchthat is relevant to addressing key climate change questions.Attitudes, social cognition, persuasion and attitude change, so-cial influence, and intragroup and intergroup behaviour, forinstance, are fundamental foci for social psychology and havedirect relevance for understanding the human and social dimen-sionsofclimatechange.Thetimeisripetounderstandtherangeof research that has been developing in social psychology onattitudes, beliefs and actions, to build upon these insights, andintegrate them with knowledge from other sciences to developmodels and theories indigenous to the climate change context.In the following section, we provide a brief overview of re-cent social psychological research that addresses three broadthemes relevant to understanding and responding to climatechange. These themes are as follows: (i) social psychologicalinfluences on climate change attitudes and beliefs; (ii) facilita-tors and barriers to climate change action; and (iii) changingclimate change attitudes and behaviour. Although there issome overlap in these themes, as an organising principle theyintuitively map on to key questions that arise in relation to cli-mate change. Our aim is to highlight recent examples of socialpsychological research that provide interesting and importantinsights in relation to these themes. Swim, Markowitz, andBloodhart (2012) have noted that much of the social psycho-logical research on climate change has emerged since 2006;we focus in on the most recent of this research that has beenpublished since 2010. We also outline how the studies in thespecial issue relate to these themes. We recognise that theseare not the only areas where social psychological researchand theory can make important contributions but they never-theless relate to key questions that need to be addressed. Weconclude the introduction by proposing considerations thatsocial psychologists could take into account in their futureresearch on climate change.European Journal of Social Psychology, Eur. J. Soc.
