Climate-Induced Migration and the Remedial Responsibilities of the Global North: A Millerian Framework for Ethical Policy Reform

Apparently, the global north’s long-held environmental invulnerability is being called into question as climate-related calamities like flooding, sea level rise, wildfires, and heatwaves worsen and result in increased migratory pressures. These climate-related hazards have multiple implications that often lead to the migration of people from areas that are already at risk, particularly from the global south, where environmental deterioration is displacing people. This problem in particular informed this study into examining the growing tension between climate vulnerabilities and the ethical duties of powerful states. In addressing the above problem, this paper adopts Miller’s theory of remedial responsibility. In a system of global interdependence, his theory serves as a normative framework that strikes a balance between the rights and obligations of sovereign states. He argues that states that have caused the most damage, and in this case, environmental damage, have a moral obligation to help and make accommodations for those affected. By adopting the method of critical analysis, this paper uses Miller’s ideas on cooperative activities and like-minded groups to support immigration policy based on reciprocity, fairness, and solidarity. It contends that while states have the presumption right to exclude, they are also obligated by justice principles to acknowledge the validity of environmental displacement and incorporate moral concerns into official policy. Accordingly, this requires Global North states to revise restrictive migration systems in light of climate-related harms. It proposes that Global North migration policy has to change in order to take into account both national interests and international justice, supporting frameworks that address climatic realities and safeguard the rights and dignity of displaced people. This paper concludes that integrating Miller’s framework strengthens both the ethical justification and practical direction for future climate-responsive migration policies.
