This monograph presents a contemporary examination of climate anxiety within schools. Featuring contributions from experts across Canada, Austria, Australia, New Zealand, the United Kingdom, Italy, and Finland, the book underscores the prevalence of climate anxiety, a phenomenon often overlooked in discussions about climate change and education. The monograph is divided into two sections. The first section begins by outlining how climate anxiety manifests in schools, examining the theoretical underpinnings of climate change education and its psychological impact on students and teachers. The second section presents innovative and practical strategies for mitigating climate anxiety in the classroom, highlighting the importance of cohesive learning environments and cross-curricular approaches. Readers will benefit from the book's international perspective and its blend of theory and practice, gaining valuable insights into how to address climate anxiety and foster resilience in educational contexts. An international, empirical, and ethnographic evidence-based perspective of climate anxiety in classroom, this book will appeal to scholars, researchers, postgraduate students, and educators with interests in climate change education, sustainability education, policy and administration, mental health, and pedagogy.
