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.[2]
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.
There are also critics of the term who argue that the term encourages a militarized response to the climate crisis, and ignores issues of maldistribution and inequity that underpin both the climate crisis and vulnerability to its impacts.[3]
Those who look at the national and international security risks argue that climate change has the potential to exacerbate existing tensions or create new ones – serving as a threat multiplier.[4] For example, climate change is seen as a threat to military operations and national security, as the rise in sea level can affect military bases or extreme heat events can undermine the operability of armies. Climate change is also seen as a catalyst for violent conflict and a threat to international security, although the causality of climate and conflict is also debated.[5][6] Due to the growing importance of climate security on the agendas of many governments, international organizations, and other bodies some now run programs which are designed to mitigate the effects of climate change on conflict. These practices are known as climate security practices. These practices stem from a variety of actors with different motivations in the sphere of development, diplomacy and defense; both NATO and the UN Security Council are involved in these practices.
