Sustainability, one of the Core Values of Librarianship, is spurring libraries to lead the way in guiding their communities towards climate action. However, because people’s lives are affected every day by the increasing frequency and intensity of natural disasters, engaging with the impacts of climate change can be an isolating and difficult experience for adults and youth alike. This hands-on guide offers a solution to cool down eco-anxiety by transforming it into a force for engagement and hope. Through programming that centers agency and belonging, librarians and educators can reframe the negative impacts of eco-anxiety into positive goals designed to inspire young people towards climate action.  Presenting 60 research-based ideas and supporting resources designed to promote collaboration and partnership, the authors walk readers through concrete, adaptable steps to impactfully integrate climate action into programming regardless of a library's size or budget. This book grounds its approach in the “triple bottom line” framework of sustainability used by ALA and the Sustainable Libraries Initiative (SLI) while also aligning with the six Shared Foundations of the AASL Standards;  directly addresses the emotional realities of eco-anxiety such as apathy, fear, and isolation by offering strategies that foster connection and resilience; shows librarians and educators how to help K-12 learners develop the mindset, skills, and knowledge required to become climate-actionable; provides primary and secondary school library lessons, children and young adult public library programs, and collaborative programs for all ages that are geared towards curiosity, agency, community, and real-world impact; and includes book lists, information about activists and organizations, and links to additional resources.
