The Migration Information Source is devoting a special series of articles to addressing how a changing climate is affecting international and internal migration now and what its effects might be in the future. The impact of climate change on human movement across the globe is likely to be profound—though perhaps in significantly different ways than are perceived today. This special issue, with articles from leading scholars, examines the connection between climate change and migration through historical, scientific, and legal overviews as well as with localized case studies from the Asia Pacific, Central America, and East Africa. The special issue is accompanied by a podcast, Changing Climate, Changing Migration, hosted by Migration Information Source Editor Julian Hattem, which you can find on this website or wherever you listen to your podcasts.
