It is widely acknowledged that climate justice has steadily grown as a field of academic engagement and is now an identifiable strand of enquiry within a number of academic traditions and arenas. While this development is a common part of the academic narrative around climate justice, there has been less interrogation of the public dimensions of this activity. What theoretical and practical challenges and opportunities does public scholarship on climate change and justice present for academics and for the communities with which they work? For roughly a decade I have purposefully sought to develop a public scholarship approach focused on the intersections of climate change and justice in my academic practice. In this chapter I use these experiences as a lens to reflect upon several of the core complexities integral to public scholarship in this arena. Specifically, I will discuss the challenges and opportunities presented by the breadth and multidimensionality of the issue; the complexity of solidarity in this multifaceted and multiscalar context; and the moral weight of climate injustice.
