Despite the substantial research into the peculiar political and legal status of climate migrants, there is comparatively little exploration of the particular forms of loss such migrants might face or how efforts might mitigate such loss. This paper aims to begin filling that void by characterizing such loss, using the framework of the UNFCC’s Warsaw Mechanism, as agential harm. Using existing models for thinking about the preservation of values and links with the past, I aim to use this idea of (...) a threat to agency to discuss how migration could occur to better preserve the agential control of displaced populations.
