"Climate change increases resource-constrained international immobility." Nat. Clim. Chang. 12, no. 7 (2022): 634-641. DOI: 10.1038/s41558-022-01401-w1758-678X1758-6798https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37376721Migration is a widely used adaptation strategy to climate change impacts. Yet resource constraints caused by such impacts may limit the ability to migrate, thereby leading to immobility. Here, we provide a quantitative, global analysis of reduced international mobility due to resource deprivation caused by climate change. We incorporate both migration dynamics and within-region income distributions in an Integrated Assessment Model. We show that climate change induces decreases in emigration of lowest income levels by over 10% in 2100 for medium development and climate scenarios compared to no climate change, and by up to 35% for more pessimistic scenarios including catastrophic damages. This effect would leave resource-constrained populations extremely vulnerable to both subsequent climate change impacts and increased poverty.en-USSocial Sciences (miscellaneous)Environmental Science (miscellaneous)Journal Article2023-08-0910.1038/s41558-022-01401-w
