Climate security is a political and policy framework that looks at the impacts of climate on security. Climate security often refers to the national and international security risks induced, directly or indirectly, by changes in climate patterns. It is a concept that summons the idea that climate-related change amplifies existing risks in society that endangers the security of humans, ecosystems, economy, infrastructure and societies. Climate-related security risks have far-reaching implications for the way the world manages peace and security. Climate actions to adapt and mitigate impacts can also have a negative effect on human security if mishandled.
The term climate security was initially promoted by national security analysts in the US and later Europe, but has since been adopted by a wide variety of actors including the United Nations, low and middle income states, civil society organizations and academia. The term is used in fields such as politics, diplomacy, environment and security with increasing frequency.
