Geopolitics and climate change are two issues that are interrelated and influence political, economic and social dimensions throughout the world. Climate change, caused by human activities, such as greenhouse gas emissions, poses a serious threat to global geopolitical stability. Countries with abundant natural resources, such as oil and gas, are experiencing new challenges in maintaining the security of their resources as extreme weather and natural disasters become more frequent. Climate change is worsening living conditions in many countries, especially in vulnerable regions such as Africa and Southeast Asia. In these areas, natural disasters often cause mass migration, triggering prolonged social and political conflicts. For example, a prolonged drought in Somalia has resulted in a wave of refugees, increasing tensions with neighboring countries and adding complexity to the region’s geopolitics. The link between geopolitics and climate change is also visible in the development of energy policy. Countries that rely on fossil fuels face pressure to switch to renewable energy to reduce carbon emissions. This transition not only requires large investments, but is also capable of disrupting established geopolitical forces. For example, the shift to renewable energy in Europe, such as the increased use of wind and solar power, is affecting relations with oil-producing countries such as Russia, which are concerned about falling demand for fossil energy. Not only that, climate change creates opportunities and challenges in the field of national security. Countries such as the Arctic, which are affected by melting sea ice, face the risk of increased territorial tensions. Access to new sea routes and open mineral resources became a source of intense competition, with countries such as Russia, Canada, and the United States increasing their military presence in the region. Regarding food security, climate change causes uncertainty in agricultural production. Rising temperatures and erratic rainfall patterns are impacting crop yields, triggering food shortages in several countries. This can exacerbate poverty and increase the likelihood of conflict. Food importing countries, such as many countries in the Middle East and North Africa, are becoming more vulnerable to global food price fluctuations influenced by climate change. Climate change is also encouraging international collaboration, with countries seeking to work together through agreements such as the Paris Agreement. However, there are still significant differences between developed and developing countries in terms of responsibility and capacity to adapt to climate change. Developing countries often feel left out of global policy, which often favors developed countries. In facing these challenges, an approach based on strengthening cooperation between countries, both bilaterally and multilaterally, is very necessary. Climate diplomacy, by involving various stakeholders, including the private sector and civil society, can be the key to ensuring sustainability and responding to the challenges faced by global society due to climate change.
