On the low-lying islands of the Pacific, the inexorable rise of sea levels is not a dire threat, but a devastating present-day reality. On the other side of the world, in sub-Saharan Africa, farmers are facing expanding deserts where their fields once flourished. These are not isolated incidents, but the interconnected effects of climate-induced displacement that threaten communities and history. This crisis transcends traditional boundaries, our understanding of the environment and human migration itself, as ecological degradation forces unprecedented numbers of people from their homes. While the term "climate refugee" is still finding its place in international legal discourse, this phenomenon is already reshaping the human geography of our planet, which has not only huge environmental and geographic consequences, but also a high human cost of this emerging form of migration.
