What Migrants Displaced By The Dust Bowl And Climate Events Can Teach Us
The World Bank predicts climate change may displace 143 million people by 2050. Environmental shifts have caused migration on smaller scales throughout the history of North America, historians say.
The World Bank predicts climate change could create as many as 143 million "climate migrants" by 2050. The result would be a mass migration twice as large as the number of refugees in the world today.
Though the size of potential displacement is unprecedented, the relationship between migration and climate has played out on a smaller scale throughout the history of North America, say historians Nathan Connolly and Ed Ayers.
Connolly, a professor at Johns Hopkins University, points to long-lasting droughts from the 12th and 13th centuries that.
