Successfully addressing climate change requires collective action. People need to adjust their behaviors, for example, by changing mobility patterns and dietary habits. These decisions are taken within a broader social context in which social norms and attitudes toward climate change play an important role. Social values also crucially shape the design of climate policies, in particular with regard to the distribution of their costs and benefits. Social change tends to occur gradually through discursive processes that are reflected in the media as well as culture and the arts. Manifestations of social change include rising awareness of climate issues around the globe and a growing willingness of people to actively address it, for example, by changing their lifestyle or getting involved in political action. In addition, citizens are increasingly adopting more climate-friendly investment behaviors and civil society organizations are resorting to climate litigation to push for more ambitious climate policies and to hold companies attempting to delay climate action accountable.
