Time to travel: climate migration in the course of history

This study examines climate migration as a historically embedded phenomenon and situates contemporary climate-induced mobility within a long-term perspective. It aims to demonstrate that migration driven by environmental change is not an unprecedented crisis, but a recurring adaptive strategy that has shaped human settlement patterns and social transformation across time. Methodologically, the article employs a historical-analytical approach based on an interdisciplinary literature review, integrating insights from environmental history, migration studies, archaeology, and climate science. Through comparative temporal analysis, it traces climate-related mobility from prehistoric periods to the present to identify structural continuities and contextual shifts. The findings indicate that climatic variability has consistently triggered significant population movements. Prehistoric migrations out of Africa were influenced by glacial cycles and desertification. In classical and medieval eras, prolonged droughts and cooling periods contributed to political instability and demographic change. During the early modern period, climate shocks intersected with colonial expansion and global trade. In the contemporary era, anthropogenic climate change has intensified displacement, compounded by border regimes, legal constraints, and socioeconomic inequalities. Theoretically, the study reframes climate migration as a long-standing adaptive response rather than solely a humanitarian crisis. Practically, it highlights the importance of historically informed and equity-based policy frameworks to govern climate-induced mobility more sustainably.
