This paper explores the concept of hope within the context of global climate change in the Nordic countries, based on a forthcoming essay for a Handbook anthology. It builds upon two systematic reviews (Aldrin 2024; Aldrin forthcoming) examining theoretical and empirical studies related to climate anxiety and actionable hope among youth. Integrating climate change issues remains complex in current educational practices – regardless of them being confessional or non-confessional. While climate change has been addressed within natural sciences and civic studies, its psychological, ethical, and existential dimensions are largely neglected. Religious communities and their leaders, alongside Nordic scholars, advocate for incorporating religious perspectives into climate change education. This paper also introduces the Collaborative Network for Climate Change in Religious Education (CORE), established in 2024 with over 40 members from Europe, Africa, and America. The network serves as a platform promoting interdisciplinary collaboration between researchers, educators, and religious practitioners. By bridging theological insights with practical engagement, the network aims to empower communities to address climate-related powerlessness through ethical reflection and practical action. This study argues that Practical Theology and Religious Education, particularly through initiatives like CORE, can effectively promote resilience and transformative hope in response to ecological and social crises.
