This book examines how climate change is reshaping not just the environment, but also global politics, economies, and societies. Through a systems-level analysis, it demonstrates the link between ecological crises and global capitalism, power struggles, and social movements. The book explains how climate change disproportionately affects the poorest and most vulnerable, particularly in the Global South. Employing world-systems theory and historical analysis, the book explores crucial issues such as fossil fuel dependence, global trade, urbanization, and resistance movements. The book also discusses the roles of Indigenous communities, youth activism, and grassroots efforts in striving for a fairer, more sustainable future. With its case studies and forward-looking insights, this book will appeal to anyone studying or working in the fields of climate justice, sustainability, or global change.
