We are out of the safe zone. Transformative Adaptation (TrAd) helps us to transform our civilisation to be in readiness for the future and makes life worth living. Impacts beyond 1.5 degrees C, the agreed maximum limit-target for global overheating, are already here. In this context, adaptation, preparedness and resilience-building are no longer optional. They become central, pivotal to whether we survive, let alone flourish. The struggle to define adaptation will be the defining struggle of the coming decade. TrAd is adaptation that works with, not against nature. It reduces greenhouse gas emissions in the same breath as it guards us against the impacts of those emissions. This book sets out TrAd as a theory and a practice, a community and an attitude. Creating a flourishing future even in the jaws of adversity requires us first to imagine it together. Thrutopias are TrAd boldly and concretely imagined. Thrutopian stories show how we can get through by adapting to what is coming at us by transforming our systems. This book unpacks the theory of thrutopias and offers existing practical examples. Transformative Adaptation is the quintessential idea whose time has come. AUTHORS: Rupert Read is co-director of the Climate Majority Project and Emeritus Professor of Philosophy at the University of East Anglia. He is the author of several books, developed the concept of Transformative Adaptation and also invented the term 'Thrutopia'; an act of imagining the actual mechanics of how we transition from this broken, collapsing world to one that is in a process of transformation and healing on all levels. Since then he has been building Thrutopianism into his creative and scenarios work, including his viral internet short Out of the Ashes. Morgan Phillips is Global Action Plan's Director of Education and Youth Engagement, and a former co-director of climate change adaptation charity, The Glacier Trust, with whom he continues to volunteer. Morgan has worked internationally in the environmental sector for over 20 years. Having returned home to west Wales in 2022, Morgan is now governor at his local primary school and a member of the education committee at Black Mountains College. Morgan's 2021 book Great Adaptations - In the shadow of a climate crisis was published by Arkbound UK and has since been published in Japanese.
