Climate change could trigger tropical evacuations, researchers advise

Global warming by just 2 degrees Celsius is likely to force some tropical plant, animal and human populations to relocate hundreds of miles from their current homes this century, according to research published today in the journal Scientific Reports.

Solomon Hsiang, Chancellor’s Associate Professor of Public Policy at the University of California, Berkeley, and Adam Sobel, a professor of applied physics and math at Columbia University, foresee dramatic population declines in Mexico, Central America, Africa, India and other tropical locales if ecosystems or humans move due to .

In their analysis, the pair used a model to demonstrate how  dynamics in the tropics can dramatically magnify the consequences of climate change as it is experienced on the ground. This means even small climate changes can have dramatic impacts.
