"140m people in three regions expected to migrate before 2050 unless environment is improved"
"Climate change will result in a massive movement of people inside countries and across borders, creating “hotspots” where tens of millions pour into already crowded slums, according to the World Bank.
More than 140 million people in just three regions of the developing world are likely to migrate within their native countries between now and 2050, the first report on the subject has found.
The World Bank examined three regions, which between them account for 55% of the developing world’s population. In sub-Saharan Africa, 86 million are expected to be internally displaced over the period; in south Asia, about 40 million; and in Latin America, 17 million."
