Investigating the UN response to the phenomenon of climate change (critical approach)

The phenomenon of climate change or climate change is one of the important issues of international organizations and its member countries. Attention to this phenomenon has been on the serious agenda of the United Nations for the last two decades. In a new approach to security studies, critical school theorists seek to create new meaning for security issues.In this context, the absence of war and military confrontations between countries does not in itself provide international peace and security, and new forms of security threats such as economic, cultural, environmental, etc. have been created.Environmental security has now replaced the threat of nuclear war. Given the importance of the phenomenon of climate change as one of the important dimensions and security concerns in the field of international relations, the question that arises in this paper is why and how the phenomenon of climate change and Has airspace become a security issue at the United Nations? The main hypothesis of the authors is that the phenomenon of climate change with the increase of human security threats, which is beyond the traditional dimensions of security (military, nuclear) has become a new form of cooperation and conflict between countries in the United Nations. Library data collection addresses the effects of climate change on various aspects of UN security and action in this area.
