Many pedagogies that seek to address the climate and nature emergency (CNE) promise hope and solutions for an idealized future. In this article, we suggest these pedagogies are rooted in the same modern/colonial system that created the CNE and other 'wicked' socio-ecological challenges in the first place, and thus they are not well-suited for preparing students to navigate these challenges. We also ask what kind of climate education could invite students to interrupt the reproduction of colonial futures, and deepen their sense of social and ecological responsibility in the present. As one possible response to this question, we offer an outline for "climate education otherwise," which seeks to prepare students with the stamina and the intellectual, affective, and relational capacities that could enable more justice-oriented coordinated responses to current and coming challenges.
