In this paper, we employ Deleuzian philosophy to explore the complex challenges confronting teachers and education systems posed by the climate emergency and the implications of the resulting posthumanist turn. Self-identified climate-activist teachers working in schools in Aotearoa New Zealand were asked to draw Deleuzian assemblages of their educational realities and of themselves while contemplating the climate emergency. Their thought-provoking drawings were used as semiotic artefacts during unstructured Zoom interviews, leading to rich conversations. Through this process, the drawings channel affect within the research assemblage, entangling the reader actively into the research process. Insights gained from the participants problematise the perspectives of teachers in response to the climate emergency and lead us to conceptualise the potential of teachers as Deleuze's nomadic change makers toward posthuman futures.
