Climate security intelligence is the capacity to warn national and sub-national security organizations of the physical effects of climate change that can have a negative societal effect on nations, governments, and their populations. This book discusses the uniqueness of climate security intelligence, the maturity of its development as a knowledge domain, and its possible future. Written by an intelligence analyst with over forty years of experience, this book centers upon the challenges that organizations may face when analysts, their managers, and their organizations are given the task of warning policymakers and decision-makers about threats to climate security. Taking a necessarily transdisciplinary approach, this book will be of interest to a wide audience of students, researchers, practitioners, and policy-makers concerned with how the impacts of climate change affect the social, cultural, political, and economic stability of national interests.
