In the Anthropocene, humans are drastically impacting the Earth system. Though the numbers are disputed, millions of climate refugees might soon appear worldwide due to, for example, rising sea levels. To better tackle these intertwined ecological and migrational crises, I expand on Seyla Benhabib’s theoretical legacy by discerning within it a multidimensional framework containing mutually intersecting moral, legal, and political dimensions. Within this framework, I argue, Benhabib approaches the issue of climate refugees from three different yet supplementary discourses. From her (...) engagement with discourses on cosmopolitanism and global justice, she endorses reforming the Refugee Convention to include climate refugees. From her contribution to discourses on human rights and human dignity, Benhabib opens the door for a human right to the environment to better protect climate refugees. Against the backdrop of her longstanding work to reformulate a feminist and critical-theoretical discourse ethics, I argue, Benhabib puts forward an ecocentric planetary ethics that embraces climate refugees and the rest of nature. In all, I conclude that Benhabib’s legacy demonstrates the need for a multidimensional approach to climate refugees in times of ecocrisis. (shrink)
