The negative consequences of climate change are becoming increasingly evident in environmental, economic, social, and political realms day by day, and no country in the world is exempt from these effects. Intergovernmental Panel on Climate Change reports reveal that climate change will be severe, which means that the world can expect more and more conflict. Climate migration and national security problems will emerge due to factors such as natural disasters and resource crises. This article aims to evaluate the relationship between climate change and migration and examine the consequences that may arise in the context of climate security in the world and in Turkey. We conclude that all countries will be affected equally severely, though in different ways, by the risks and consequences that will gradually emerge in the context of climate security in parallel with climate change, and that the number of climate migrants and refugees will increase globally in the coming period. Further, migration to Turkey will not only be from neighboring countries but will increase from wider geography in the future due to Turkey’s geopolitical eminence.
