Finally, a way to make conservatives think about the profound societal impacts of global warming:
Continued climate change will drive Mexican farm workers to migrate to the United States in greater numbers, environmental experts predicted on Monday.
For every 10 percent of lost crop yields, 2 percent more Mexicans will leave and most will try to come to the United States, Michael Oppenheimer of Princeton University in New Jersey and colleagues predicted.
Oppenheimer’s team looked at Mexican census data from 1995 to 2005, along with statistics on crop production and climate data. “We lined up the climate changes, the crop production changes … with the census data, which allowed us to infer the emigration rate,” he said.
“Climate change is expected to cause mass human migration, including immigration across international borders,” Oppenheimer and his team wrote in the Proceedings of the National Academy of Sciences.
Conservatives may be willing to shrug off the possibility of rising sea levels, desertification and mass extinctions, but can they live with the risk of more Mexicans crossing the border to breathe their precious American air?
On the other hand, they might just be grateful for another excuse to turn the U.S.-Mexico border into a giant moat full of sharks with frickin’ laser beams on their heads.
