ScienceDaily (Oct. 27, 2011) — Governments around the world must be prepared for mass migrations caused by rising global temperatures or face the possibility of calamitous results, say University of Florida scientists on a research team reporting in the Oct. 28 edition of Science.

If global temperatures increase by only a few of degrees by 2100, as predicted by the U.N. Intergovernmental Panel on Climate Change, people around the world will be forced to migrate. But transplanting populations from one location to another is a complicated proposition that has left millions of people impoverished in recent years. The researchers say that a word of caution is in order and that governments should take care to understand the ramifications of forced migration.

Wasted resources and the costs of malnutrition, declining health, infant and elder mortality, and the destruction of families and social networks should be included in the total cost of a failed resettlement, he said.
