Will a hotter climate mean more immigration? In some places, yes, that's quite possible. Earlier this week, a team of researchers led by Princeton's Michael Oppenheimer published a study suggesting that as global warming causes agricultural yields in Mexico to decline, an additional 1.4 million to 6.7 million Mexicans could migrate to the United States by 2080. (The team analyzed data on emigration, crop yields, and climate from 1995 to 2005 in order to make their forecasts.) As always, caveats abound. The social consequences of global warming are always the hardest things to predict.

The brief, three-page climate accord that came out of Copenhagen last December was, you'll recall, incredibly vague. There was some happy talk in the document about reducing emissions and sending aid to poorer countries, but few actual details. So, as Lisa Friedman reports in ClimateWire today, the task for lawyers and bureaucrats in the coming months will be to figure out what all those amorphous directives actually mean: The first real test of the accord comes Jan. 31, the deadline for both rich and poor countries to submit their economywide emission targets to the United Nations.
