and is mirrored by the lack of progress made by salient political summits (Rogelj et al., 2010). Perhaps as a response to this, scholarly journals and articles that are focused on climate change are growing. Natural scientists tell us that we know what needs to be done to avert dangerous climate change (IPCC, 2014), and economists tell us that delaying action in the short term will lead to much greater costs in the long term (Stern, 2007). Understanding public responses to climate change and developing solutions to catalyse action is a critical challenge for the social sciences, and we propose that the development and elaboration of a social psychology of climate change would be a cornerstone of such an approach.We do not make the claim that social psychology has all the answers but rather that the theories, models and research methods of social psychology can provide a powerful arsenal to complement the approaches of other disciplines. Researchers have already begun to apply social psychological theory and methods to the issue of climate change, and we highlight in the following sections examples of the insights that have flowed from this. We cannot assume, though, that our theories and findings will automatically generalise to the climate change context. As Moser (2010) has noted, there are unique dimensions to climate change that make it distinct from other environmental, risk and health issues: The causes of climate change are invisible to humans, the impacts are distal and it is complex and riddled with uncertainties. Modern urban humans are to some extent insulated from their physical environment, and the lags between the climate and social systems make it difficult for people to understand their role in influencing climate.These factors suggest the importance of developing a social psychology of climate change, empirically testing, integrating and refining existing theories and models to develop new frameworks. The notion that psychology can play a role in understanding and addressing climate change is not a new one. The American Psychological Association's Task Force on the interface between psychology and global climate change comprehensively detailed the ways in which psychological research can help to understand people's perceptions of the risks of climate change, the contribution of human behaviour to climate change, the psychosocial impacts of climate change, the ways in which people can adapt and cope with climate change and the psychological barriers that could limit climate change action (Swim et al., 2009.It is also not a new idea that social psychology can play an important role in understanding and addressing environmental problems and solutions (Clayton & Brook, 2005). Social psychology, specifically, has a long tradition of theory and research that is relevant to addressing key climate change questions. Attitudes, social cognition, persuasion and attitude change, social influence, and intragroup and intergroup behaviour, for instance, are fundamental foci for social psychology and have direc...
