The book provides a critical analysis of the nexus between climate change, security and politics, especially in relation to the role and impact of societal agencies such as states, corporations, military, financial institutions and community organizations in framing and responding to climate change using various forms of social, economic or political leverage. Climate change is a major existential security threat to the planet and humanity, yet there is continuing debate as to how it should be approached.
