New climate migration modelling puts a human face on climate impacts

New climate migration modeling work projects increased numbers of people moving within their countries in the developing world—as many as 216 million internal migrants by 2050. The modeling completes work for the World Bank that was released in 2018 as volume 1 of Groundswell. The Climate School's Center for International Earth Science Information Network (CIESIN) has once again partnered with the Bank, the CUNY Institute for Demographic Research, and the Potsdam Institute for Climate Impacts Research to model the remaining World Bank Regions. The completed work, now released in Groundswell Part II, focuses on three new regions—North Africa, Central America, and the Lower Mekong—and includes reviews of climate migration issues for small island developing states (SIDS) and the Middle East. The projected total of "climate migrants" by 2050 in the countries featured in Map 1 is between 48 million (at the low end of the climate friendly scenario) and 216 million (at the high end of the pessimistic scenario).
