In recent years climate change has increasingly been considered as a threat to international peace and security. This thesis examines how the framing and agenda setting of climate change as a threat has changed in Sweden after the Cold war. By using an explanatory model and focusing on external factors, such as international events and Swedish international identity, the thesis seeks to develop a greater understanding of how external factors effect national framing and agenda setting of climate change. The thesis concludes that military threats does not prevent climate change for being considered a security threat, and that a greater European identity may cause less focus on military insecurity and more focus on alternative threats.
