Extreme Weather Drives Migration Surge at U.S.-Mexico Border

A new study reveals that climate change-induced weather extremes are increasing undocumented migration between Mexico and the United States.

Research published in the Proceedings of the National Academy of Sciences links extreme weather to higher rates of undocumented migration from Mexico to the U.S.
The study found that people from Mexican agricultural areas are more likely to migrate after droughts and less likely to return when extreme weather persists.
Mexico's rising temperatures and severe droughts have drained reservoirs, caused water shortages, and reduced corn production, threatening rural livelihoods.
The findings highlight that developed countries, which contribute more to climate change, have a responsibility as developing nations bear its impacts.
The study underscores the need for global collaboration on migration and climate resilience, as political climates in the U.S. shift towards stricter immigration policies.
