"Extreme weather is contributing to undocumented migration and return between Mexico and the United States, suggesting that more migrants could risk their lives crossing the border as climate change fuels droughts, storms and other hardships, according to a new study.
People from agricultural areas in Mexico were more likely to cross the border illegally after droughts and were less likely to return to their original communities when extreme weather continued, according to research this week in the journal Proceedings of the National Academy of Sciences.
Across the globe, climate change — caused by burning fossil fuels such as coal and natural gas — is exacerbating extreme weather. Droughts are longer and drier, heat is deadlier and storms are rapidly intensifying and dumping record-breaking rain.
In Mexico, a country of nearly 130 million people, drought has drained reservoirs dry, created severe water shortages and drastically reduced corn production, threatening livelihoods."
