Climate Change Will Trigger 140m Migrants By 2050

The climate-change effects most likely to force migration will be drought, crop failure, sea level rise, and increased storms.

But a new report released by the World Bank on Monday honed in on the problem of internal displacement, finding that as many as 140 million people in three densely-populated, developing regions might be forced by climate change to migrate within their countries' borders by 2050.

Preparing for Internal Climate Migration, is the first and most comprehensive study of its kind to focus on the nexus between slow-onset climate change impacts, internal migration patterns and development in three developing regions of the world- Sub-Saharan Africa, South Asia and Latin America.

The report - titled Groundswell - Preparing for Internal Climate Migration - said the three regions represent 55 percent of the developing world's population.

Gilbert Houngbo, the president of the International Fund for Agricultural Development (IFAD), a United Nations agency based in Rome, said that the problem of migration was likely to increase among small farmers exposed to global warming.

The report shows that with strong global efforts to cut greenhouse gas emissions and good development planning in each country, the number of climate migrants could be reduced dramatically - from a projected 140 million people to 40 million people by 2050.

World Bank's chief executive officer, Kristalina Georgieva said the new research provides a wake-up call to countries and development institutions.

U.S. District Judge William Alsup is inviting oil and gas companies and climate scientists to present the best available knowledge on climate change in his courtroom, according to a new report by the New York Post.

The research team, led by World Bank Lead Environmental Specialist Kanta Kumari Rigaud, include researchers and modellers from CIESIN Columbia University, CUNY Institute of Demographic Research, and the Potsdam Institute for Climate Impact Research.

The mass migration is likely to spur millions of people in poor, rural areas to flock to major cities, which need to start ramping up their infrastructure, social services and employment opportunities now. "While internal climate migration is becoming a reality, it won't be a crisis if we plan for it now".

The researchers say that regional climate variability, such as differences in atmospheric circulation, precipitation, and existence of green spaces affect when human-caused climate change will become the primary driver of extreme heat events.
