In its reports published in 2019, the Intergovernmental Panel on Climate Change (IPCC) identified climate change as a potential accelerator or intensifier of security risks in the world. The link between climate and security has also been highlighted by both American and European research centers, particularly in publications financed by the defense sector since the early 2010s. These teams of experts have indeed published a growing number of reports studying the impact of climate change on armed forces’ missions. Yet, these experts have recently gone beyond the initial requests of national militaries and have decided to join new international networks on climate security. As shown in this article, these networks thus participate in current international negotiations taking place in several forums on climate and security, with the goal of highlighting a security and military perspective on climate change. We will focus on the case of the International Military Council on Climate and Security (IMCCS) and its involvement in two international negotiation forums (the Planetary Security Initiative and the Munich Security Conference). This contribution builds on a series of interviews conducted in Paris, Washington, and The Hague with both American and European experts, and on an analysis of institutional archives.
