In this paper, I will lay out some useful conceptual/theoretical markets that will help us to understand, and resolve, significant political challenges to ‘action’ on climate change migration. Thus, while this paper is concerned with climate change and migration responses, it is also concerned with understanding how we understand migration in the context of climate change, and how climate change forces a radical shift in such understandings. To do so, I pick up on the work of Robert W. Cox and push it in a different direction. In particular, I am interested in his work on civilizations, and how this civilizational account of world politics opens up space for thinking about climate change broadly, and climate change migration specifically. I argue that Cox’s account of ‘inter-civilizational’ politics helps us to solve a pressing analytical problem: how to rethink the coordinates of contemporary cosmopolitics in the ‘Anthropocene’, and reconsider the frames of analysis that we adopt to understand and respond to climate change migration. I demonstrate this by considering two distinctly different ‘civilizational’ accounts of migration and mobility in the Asia-Pacific/Oceania region (one territorial and the other maritime), and consider how these might reveal an important source of future change. By sketching out this approach, my intention is to mobilize the resources offered by Cox in order to further his project of envisaging alternative world orders, and post-hegemonic political relations therein.
