How will the unprecedented changes to climate, and the economic transitions required to stave off the worst effects of climate change, affect regional and international security dynamics? Physical scientists have been informing us for many decades now that human-induced climate change is a severe threat to the planet and our ability to live on it. Scholars have only more recently begun to grapple seriously with the implications of changing climate on issues of international and regional security. Climate change is a global phenomenon, but its effects on security will play out in different ways around the globe. Regional perspectives are therefore crucial to understanding these issues. We aim to facilitate a dialogue and to begin to build a global community of interdisciplinary scholars, experts, policy-makers, and activists working to understand how climate change will affect regional security dynamics.
