Climate change has become a profound global concern, affecting many aspects of life, including global security. The impact of this climate shift can be seen in several interrelated dimensions, including social conflict, forced migration, and threats to natural resources. One of the main impacts of climate change on global security is the increased risk of conflict. Extreme changes in temperature and rain patterns can cause damage to agriculture, resulting in food shortages. When societies face scarcity, tensions between groups can increase, creating opportunities for armed conflict. Regions vulnerable to this include sub-Saharan Africa and the Middle East, where disputes over water and land are more common. In addition, the impact of climate change is driving massive migration. When areas become uninhabitable due to rising sea levels, pollution, or natural disasters, many individuals are forced to leave their homes. Scientists estimate that by 2050, up to 200 million people could become climate refugees. This kind of migration often creates tension in the destination country which can create conditions of instability and social unrest. Food security is also a serious concern due to climate change. Temperature fluctuations and water scarcity affect agricultural yields, threatening food security worldwide. Countries that depend on traditional agriculture tend to be more vulnerable to food crises, which in turn can trigger unrest and social instability. Energy crises and public dissatisfaction with the government often arise in response to food shortages. In the energy context, the shift towards renewable energy sources can be a double-edged sword. On the one hand, this transition could reduce carbon emissions, but on the other hand, dependence on resources such as lithium and cobalt for batteries could create new competition for these resources. Countries will seek to secure access to these raw materials, raising the potential risk of new conflicts. The emergence of extremist groups is also a growing concern. In difficult situations, these groups can use population dissatisfaction regarding the impacts of climate change to recruit new members, capitalizing on social unrest arising from economic and environmental hardship. Overall, the impact of climate change on global security is complex and profound. The emergence of new conflicts, mass migration, food crises, and challenges to social stability are some of the aspects that the international community must face. Strengthening international cooperation in dealing with the impacts of climate change and improving adaptation and mitigation policies are important steps in maintaining global security in the future.
