This guide to transformative skills for climate action expands climate literacy to encompass those inner skills, qualities and capacities that help translate scientific understanding into transformative shifts in the way we do things, individually and collectively. The hope is that this guide will help educators, communicators and practitioners equip the whole of society with these essential resources. This guide introduces a table of 23 inner skills that are helpful for collective action to reduce environmental harm and adapt to a changing climate. These skills, including complexity awareness, appreciation and creativity, are intended to be broad and transferable to multiple contexts. They can be cultivated in K-12 education, higher education, professional development, community learning, faith groups, families, and other learning environments.
