Climate change – seen through the structural concerns of a globalized world, its effects on sovereignty and its relationship to the security dilemma. Environmental Security - A Post-Cold War Concept - reconsiders the subject matter of security (in international relations), from state-based thinking, to a council's human security agenda. Although the scope of security has changed, it is still applied in the field of security studies through engaging the dominant themes of traditional security ideals. It is with this assumption that this essay aims to address the key concepts of Environmental Security through climate change. By looking at how climate change influences the behavior of states, we can see that it can both exacerbate existing tensions and create new ones in the international system. The question of scarcity and its challenges to claims of sovereignty and security, whether environmental threats have the potential for war, and how intact environments loom large over these discussions. The aim is to criticize political reasoning, to reveal the implications of climate change, through the manifestation of its potential consequences. To evaluate climate change from a security perspective it is necessary to consider its potential future implications as well as their magnitude for different countries. States and groups. It is clear that everyone will suffer the effects of climate change, even if the effects will be uneven and disproportionately distributed. States with lower adaptive capacity, which can be determined by levels of “human health and food security, self-confidence, government capacity and poverty/development,” intensify their vulnerability to the effects of climate change. The manifestations of climate change in the future but…… middle of paper … function of the purpose of a state as its responsibility towards its citizens. Ultimately – Environmental security aims to increase the capacity of the state, community and individual to cope with limited natural resources and risks, conflicts and changes due to environmental factors. What is most concerning to anyone looking at these issues from a security perspective is not a single concern, but the totality of the growing impact of disruptions caused by faulty modern industrial systems and its reach across all parts of the biosphere. Competition for resources and territory, decreasing access to food and water, and threats to sovereignty have brought changes in military planning and foreign policy, as well as adaptations in the international legal system, with climate change and security environmental issues that profoundly shape 21st century nature.
