Global warming and extreme heat are behind many of the phenomena linked to climate change. Hotter weather also has an impact on migration and on migrants, ranging from destinations such as the Middle East to parts of the United States. In recent years, there has been more attention paid to cases of migrant workers dying from the heat. In this episode of our Changing Climate, Changing Migration podcast, we speak with Tord Kjellstrom, a physician and researcher who has closely studied the relationship between extreme heat and population health, about what extreme heat means for migrants.
