A new study in the Proceedings of the National Academy of Sciences examining the effects on immigration of decreased crop yields due to climate change finds that by 2080 millions of Mexican farmers could be forced to migrate north into the United States. The study shows that for every 10% decline in crop yields, 2% of Mexicans are likely to leave the country.

In terms of specific numbers, there is a wide range, depending on which global warming scenario is run: Between 2% and 10% of the current population of Mexico aged 15-65 could become climate change refugees. That's 1.4-6.4 million people. (BBC News)
