It is clear that climatic events can have immediate impacts on human security (health, livelihood, food security), but does climate change also constitute a direct threat to peace, security and societal stability? This report discusses three aspects of relevance to the larger debate on the nexus between climate change, violent conflict and security: (i) the evident concentration of armed conflict in environmentally fragile regions; (ii) the scientific evidence base for a causal relationship between adverse climatic changes and armed conflict; and (iii) the role of climate-related security threats in a comparative perspective.
