The impact of climate change on global security is becoming an increasingly pressing issue. Extreme weather phenomena, rising sea levels and changes in rainfall patterns can threaten political and social stability in various parts of the world. One of the most significant impacts is an increased risk of conflict. Increasingly scarce natural resources, such as clean water and fertile land, can trigger tensions between groups within countries and between countries. Climate change is also playing a role in increasing forced migration. Severely affected areas, such as coastal areas and agricultural zones, encourage residents to move in search of safer places. This mass migration can cause pressure on infrastructure and public services in destination areas, potentially leading to social instability. Destination countries are often unprepared for sudden population surges, leading to tensions between communities. Furthermore, conflicts fueled by climate change often occur in already vulnerable areas. For example, in Sub-Saharan Africa, the phenomenon of prolonged drought has increased tensions between farmers and herders, leading to armed confrontations. Climate change functions as a “threat multiplier,” exacerbating existing conflict situations. This impact is not limited to developing countries. Developed countries also face security challenges related to climate change. A striking example is the increasing risk of natural disasters that disrupt domestic security, such as forest fires, storms and floods. Climate change has the potential to reduce economic competitiveness, which in turn can disrupt political stability. In an international context, climate change could trigger a race for control of increasingly scarce resources. The scope of these disputes could include access rights to water, renewable energy and mineral resources. For example, the Arctic region, experiencing melting ice, promises access to new shipping routes and valuable mineral deposits. International tensions may increase as countries attempt to claim these territories and resources. To overcome the impact of climate change on global security, international cooperation is very important. Handling climate change requires a multilateral approach that includes mitigation and adaptation strategies. International platforms such as the Paris Agreement provide a framework for global collaboration, although implementation is often hampered by domestic politics. Efforts to reduce greenhouse gas emissions and invest in green infrastructure are key to reducing more severe impacts in the future. Education also plays an important role in preparing society to face climate change. Awareness of environmental issues and their impact on daily life can help increase social resilience. This awareness can build solidarity and dialogue between communities to reduce the risk of conflict. The importance of research and development in environmentally friendly technology cannot be ignored. Investments in low-emission technologies and nature-based solutions will help society adapt to the changes that are already occurring. Collaboration between governments, companies and the scientific community is needed to create sustainable innovation. With proactive steps, the negative impacts of climate change can be minimized. All parties, including individuals, organizations, governments and international institutions, must play an active role in formulating long-term solutions to face today’s challenges. Future global security depends critically on our ability to unite and act to address the threats posed by climate change.
