This book examines the increasingly urgent intersection of climate change, human security, and politics, particularly in light of worsening climate disasters. Climate change has evolved into a political arena shaped by diverse actors including states, corporations, civil society, and indigenous groups, all competing for authority, legitimacy, and power. Through an interdisciplinary and eclectic approach, the book transcends traditional paradigms of mitigation and adaptation, critically examining how climate narratives are used as political capital. It explores the intricate power dynamics, governance challenges, and ethical dilemmas. By exploring region-specific studies across Europe, Latin America, Oceania, and Africa, it challenges readers to rethink climate security not as a fixed concept, but as one shaped by competing interests, uneven vulnerabilities, and global inequalities. The book ultimately seeks to inform and empower stakeholders to better address climate change as both a security crisis and a political struggle.
