Geopolitics and global climate change have become interrelated topics in the last decade. Global warming affects state power dynamics, resources, and political stability around the world. Countries most affected by climate change are often in a weak position, exacerbating tensions between countries and fueling conflict. One of the direct implications of climate change is population movement. Sea level rise, drought, and natural disasters result in mass migration. Regions such as Southeast Asia and parts of Africa are particularly vulnerable to climate change, which could trigger large numbers of refugees, creating challenges for neighboring countries that must receive them. This can exacerbate social and political tensions in recipient countries. On the other hand, countries with abundant natural resources, such as fresh water and fertile land, may gain more power in geopolitical negotiations. For example, potential conflicts over water access could increase in drought-stricken areas. Major rivers in the Middle East and Africa can become flashpoints for tensions, with countries fighting for control of increasingly scarce resources. Renewable energy, as a solution to climate change, also has geopolitical implications. The transition from fossil fuels to clean energy can change the global power map. Countries that quickly adapt to green technologies may increase their influence internationally, while countries dependent on oil and gas production may experience a decline in economic power. Climate change also affects global agriculture. Rising temperatures and erratic rainfall patterns could affect agricultural yields, potentially leading to a food crisis. Countries that rely on food exports may face new challenges in meeting their domestic needs and in international markets. The reduction in biodiversity due to climate change also has an impact on species and ecosystems, which has an impact on human life. Countries that depend on certain ecosystems for income and livelihoods face greater risks. International cooperation is crucial in facing this challenge. Agreements such as the Paris Agreement demonstrate global efforts to address climate change, but their implementation is often influenced by political interests. Countries with strong economies may be less likely to meet global commitments, exacerbating disparities between developed and developing countries. This crisis also creates new opportunities for sustainable business and innovation. The green technology sector and sustainability initiatives are gaining more support, giving rise to new leaders in global geopolitics. Collaboration between countries in clean energy research and development can create stronger networks to address shared problems. In the context of national security, countries increasingly view climate change as a threat. Military strategies now often include climate risk analysis as an important consideration for maintaining stability. Changes in climate can result in potential conflict, making this issue a major concern for policymakers around the world. Climate change, then, is not only an environmental problem, but also a very deep issue in global geopolitics. Countries must prepare and adapt to these challenges to ensure their future security and prosperity.
