IGOs and Global Climate Security Challenges: Implications for Academic Research and Policymaking

Climate change poses a new class of security challenges that is confronting societies worldwide. Increased risk of famine, destroyed infrastructure, houses and shelter, and violent conflicts might all be consequences of climate change through gradual changes to ecosystems and extreme weather events. As a way to mitigate these challenges, states have delegated increased power to intergovernmental organizations (IGOs).

This Fact Sheet summarizes the key findings of the first systematic review of research on IGOs and climate security, and the implications of existing studies for the theory and practice of global climate security governance.
