In this chapter we explore the emotional processes underpinning and shaping global climate activism. We understand the global sphere as a social sphere that transcends and operates at degrees of autonomy from the national, regional or local level (e.g. Scholte 2005, see also Chapter 1). At the same time, while the emotional bases of activism are widely recognized in research, little has been done to clarify the formation of activist emotions under conditions of globality. “Research on transnational movements is scarce and little has been done on emotions across borders” (Flam 2013a: 326). This is especially true for the global perspective we adopt here (see Flam 2005, 2013a, 2015a). 1
