Climate change has become one of the greatest challenges facing global society today. The impact is not only felt in the form of increasing natural disasters, but also encourages large-scale conflicts. Countries that rely heavily on natural resources, such as water and agricultural land, face serious threats to international stability and security. Climate change increases the frequency and intensity of extreme weather phenomena. For example, prolonged floods and droughts can worsen the economic conditions of already vulnerable communities. As resources become scarce, conflicts over access to clean water and fertile land become more common. In this context, Sub-Saharan Africa and South Asia are the regions most vulnerable to tensions due to climate change. Rising global temperatures also contribute to mass migration. Residents who lose their homes due to rising sea levels or natural disasters tend to seek shelter in safer areas. This creates tension between refugees and local residents, which can lead to violence. In Europe, demographic shifts resulting from migration have added to social and political challenges, fueling a resurgence in anti-immigrant sentiment. Additionally, declining biodiversity as a result of climate change threatens the livelihoods of many communities that depend on agriculture and fishing. Significant economic losses cause discontent, which often leads to protests and violence. In this context, it is important for the government to implement effective adaptation policies to mitigate these negative impacts. Climate change is also a triggering factor for geopolitical conflict. Countries that share resources, such as rivers and lakes, may become embroiled in disputes when access to water becomes scarce. An example is the tension between countries in the Middle East and Central Asia regarding the use of limited river water. It is important for the international community to mitigate the risk of conflict due to climate change. Collaboration between countries is essential to overcome this problem. Sustainable development, green technology and wise resource management can help prevent future tensions. International conferences and multilateral agreements are also needed to strengthen global cooperation in facing the challenge of climate change. Through a comprehensive and inclusive approach, we can build community resilience to the impacts of climate change. The involvement of all stakeholders, including governments, non-governmental organizations and civil society is essential in realizing sustainable solutions. An emphasis on education and public awareness regarding the impacts of climate change can also help foster a better response to this crisis. The uncertainty caused by climate change demands immediate action. By understanding the relationship between climate change and international security, we can prepare ourselves for greater impacts in the future. Appropriate policies and actions can help prevent conflicts driven by resource scarcity and ensure greater global stability.
