امروز خبری منتشر شده است از گزارشی در رد اثرات مهاجرتی تغییرات اقلیمی. این گزارش که جزییات بیشتری در مورد آن اینجا قابل دسترسی است مدعی شده است که تغییرات اقلیمی باعث بروز مهاجرت انبوه نخواهد شد. این در حالی است که برخی مقالات منتشر شده در سال های گذشته از احتمال قوی وقوع مهاجرت های انبوه داخلی (در درون یک کشور) و خارجی (میان کشورها) به دلیل پیامدهای تغییرات اقلیمی خبر می دهند. این گزارش بر اساس مشاهدات انجام شده در برخی کشورها این ادعا را رد می کند. 

Recent studies in Bolivia, Senegal and Tanzania found no evidence that environmental degradation would result in large flows of international migrants, the IIED report said.

Most displaced people wanted to stay as near to their homes as possible and most stayed within their own borders, study lead author Cecilia Tacoli said.

"Environmental change undoubtedly increases the number of people mobile," she said. "But catastrophe like droughts and floods tend to overlap with social and structural upheaval, like the closure of other sources of local employment that might have protected people against total dependence on the land.

"Of course we need to act on climate change, and rich nations have a moral obligation to help poor people affected by it," Tacoli said. "But it's often easier and quicker to address the socio-economic factors."
