Crop Yields Could Force Up to An Extra 100,000 Mexicans Per Year to U.S.
"A reduction in crop yields caused by global warming could mean up to 6.7 million additional Mexicans will emigrate to the United States by 2080, says a study by Princeton University researchers," the Christian Science Monitor reports. The study itself, by Alan Kruger and two other professors at Princeton, focuses on agricultural yields by studying the 1995 - 2005 period, to determine the impact of an expected decline in yield from warming over the next 80 years. The study's appendix has more information about how the calculations were done. The total calculated "extra" migration is an estimate, although most media reports picked the high number of 6.7 million and not the lower 1.4 million.
