The planetary crisis facing humanity makes essential the incorporation of learning about climate change and sustainability in the university curriculum. Yet the ooting of climate change in values, knowledge systems and societal structures means that this incorporation must be more than just addition of knowledge content into a pre-existing curricular template. This article argues that the shifts required in a deep treatment of the climate crisis serve a broader purpose in driving positive change in university teaching and learning. Even within the confines of existing disciplinary divisions and mainstream epistemologies, possibilities exist for deepening critical reflection, pushing boundaries and opening imagination. The article explores this potential through an assessment of three spheres of enquiry: the ontological, epistemological and axiological. The teaching of these areas should be underpinned by the complimentary pedagogical foundations of critical questioning and deliberation, leading to a virtuous cycle of deepening of understanding and connection.
