A warming climate could see millions of adult Mexicans migrate to the US as rising temperatures cause a drop in crop yields, according to a study by researchers at Princeton University.

The research draws a clear connection between climate change and immigration – two heavily debated issues in the US.

It says warming may bring between 1.4m and 6.7m Mexicans to the US by 2080.
