Climate change has become a deep and complex global issue, having implications for various aspects of human life, including world security. Phenomena such as rising temperatures, extreme weather and rising sea levels are creating new challenges that affect political and social stability around the world. The impact of climate change on world security can be seen in several aspects. First, climate change contributes to the intensification of resource conflicts. In many cases, the scarcity of clean water and fertile land leads to disputes between communities and states. In already vulnerable regions such as the Middle East and Sub-Saharan Africa, climate change is exacerbating existing tensions, forcing communities to compete to meet basic needs. For example, in the Lake Chad Region, reductions in water and fertile land result in mass migration, which often leads to conflict. Second, mass migration as a result of climate change can create tensions in destination countries. As tens of thousands of people move in search of safer homes, countries with weak infrastructure are often ill-equipped to accommodate this migration flow. This can trigger xenophobia, social instability and conflict between migrants and local residents. European countries, for example, face major immigration challenges due to environmental factors, which influence their political and social policies. Third, climate change also has an impact on global food security. Rising temperatures and changes in rainfall patterns can disrupt agricultural production. This leads to rising food prices and potential famine, especially in countries that rely heavily on agriculture. Food insecurity can trigger social unrest and increase tensions between communities. Scientists warn that without effective mitigation measures, countries with low food security could experience collapse due to a food crisis. Fourth, climate change can damage critical infrastructure, including energy and transportation resources. Increasingly frequent natural disasters can destroy communication and transportation links, disrupt aid distribution, and hinder disaster response. This delay in response not only threatens human lives but can also create space for extremist groups who take advantage of the resulting chaos. Finally, climate change has implications for international cooperation. Countries in the world are faced with the challenge of working together to overcome environmental impacts that know no borders. Climate diplomacy is important to prevent new tensions from emerging. However, when countries prioritize their national interests, this cooperation is often hindered, creating the potential for future conflict. In the face of the increasingly real impacts of climate change, it is important for countries to collaborate in sharing technology, knowledge and resources. Only with an integrated approach can global security be optimized in the face of growing climate challenges.
