The piece foregrounds a climate justice frame, noting the Global North’s historical responsibility and that climate finance, including a Loss and Damage Fund, fell short of commitments by wealthy nations as of 2025.

Policy recommendations call for addressing internal displacement in vulnerable countries, ensuring responsibility from historically polluting nations, and developing safe, regular pathways for climate-related migration.

Recent legal developments include a July 2025 ICJ advisory opinion sparked by the Vanuatu ICJ Initiative, declaring the climate crisis an urgent existential threat and urging state cooperation and ambitious climate action.

Key players cited encompass UN agencies, climate justice movements, academics, and activists pushing for stronger legal recognition and protection of climate migrants.

Climate change is driving mass displacement, with projections of up to 1 billion climate refugees by 2050 and extensive internal displacement, poverty, and instability.

The author critiques the notion that expanding the Refugee Convention to cover climate displacement is a cure-all, arguing such expansions have historically served capital interests over refugees.

Efforts to expand protections include discussions on temporary protection, humanitarian visas, and broader frameworks like the Guiding Principles on Internal Displacement, the Global Compact for Migration, and the UNFCCC, though none provide binding international protection for climate migrants.

Climate refugees currently lack legal protection under international law, since the Refugee Convention covers persecution and violence, leaving many displaced by environmental factors in legal limbo.

The overall tone advocates preventive measures, fair treatment of refugees, and a new comprehensive legal framework to safeguard vulnerable populations amid climate displacement.
