More than 140 million people in Africa, Latin America and South Asia could move to another part of their country by 2050 to escape the worsening impacts of climate change — unless urgent action is taken to curb global warming and help people adapt, the World Bank said Monday.
Globally, the numbers of people forced to leave home because of water shortages, crop failures, sea-level rise, storm surges and other climate threats are likely to be much higher, researchers said.
But if global warming is effectively kept to limits set in the Paris Agreement on climate change, and people are helped to adapt, then the numbers migrating in the three regions will drop to about 40 million people, the study predicted.
