In an age of climate disruption, economic insecurity, technological acceleration, political fracture, and intensifying great-power rivalry, crises no longer arrive one at a time.Global Polycrisisoffers a clear and compelling guide to the defining condition of our century: the convergence of multiple large-scale disruptions that interact, amplify one another, and defy conventional solutions.Organized around eight interlocking domains-energy, economy, technology, Earth systems, food, ideology, mental health, and geopolitics-the book shows how ecological overshoot, precarity, social fragmentation, and militarized competition are not separate problems but expressions of a deeper systemic disorder. Each chapter pairs rigorous analysis with an experiential project that moves learning beyond abstraction, inviting readers to connect planetary-scale forces to everyday institutions, and personal lifestyle choices.Ideal for upper-level undergraduate and graduate courses in global studies, leadership, environmental studies, political economy, and related fields, this book also speaks to educators, practitioners, and serious readers seeking an accessible, ethically grounded framework for understanding a turbulent world.
