More than 200 million climate refugees by 2050

(Barcelona) Climate change could force more than 200 million people to leave their homes over the next three decades and create massive migration unless urgent action is taken to reduce global greenhouse gas emissions and closing development gaps, according to a World Bank report.

Part two of the Groundswell report released on Monday examined how slow-onset climate change impacts such as water scarcity, declining crop productivity and rising sea levels could lead to millions of people. , describe as “climate migrants” by 2050 under three different scenarios, involving varying degrees of climate action and development.

In the most pessimistic scenario, with a high level of emissions and uneven development, the report predicts that up to 216 million people will move within their own country in the six regions analyzed. These regions are Latin America; North Africa ; Sub-Saharan Africa ; Eastern Europe and Central Asia, South Asia and East Asia and the Pacific.

In the most climate-friendly scenario, with low emissions and inclusive and sustainable development, the world could still see 44 million people forced to leave their homes.

The results “reaffirm the power of climate to drive migration within countries,” said Viviane Wei Chen Clement, senior climate change specialist at the World Bank and one of the report’s editors.
