Despite heightened awareness of climate change, military administrations prioritize national security over human and ecological security, evident in their strategies and actions where national objectives take precedence. The military's discourse on climate security often portrays vulnerable groups in the global south as threats rather than recognizing them as the ones threatened, potentially leading to security measures that harm these populations, such as strict state protection against migrants at external borders. The thesis emphasizes the impact of securitizing actors and unequal power relations on dominating the climate security discourse, advocating for a broader perspective that extends beyond national security to address the needs of vulnerable individuals, communities, and ecosystems.
