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.

Wildfires destroying homes in the Midlands and Shropshire crews moving between fire and flood show why sustainable construction must now treat climate resilience as a core design requirement. Sustainable building design, low carbon design and eco-design for buildings need to account for overheating, fire risk, drainage capacity, defensible space and durable fabric performance.
Whole life carbon, embodied carbon and life cycle cost are becoming inseparable from safety, insurability and asset value, making whole life carbon assessment and lifecycle assessment essential tools for developers, councils and investors.
Karachi’s mangrove loss reinforces the construction value of green infrastructure and nature-based flood protection. Tidal creeks, mangrove belts and resilient coastal landscapes can reduce erosion, store carbon and protect communities, supporting environmental sustainability in construction without relying solely on hard engineering. For sustainable urban development, green construction and eco-friendly construction must prioritise site planning, biodiversity and building lifecycle performance alongside energy-efficient buildings and net zero carbon buildings.
Plans for a wind-turbine recycling facility in the Scottish Highlands point to a more mature circular economy in construction. Renewable infrastructure must address end-of-life reuse in construction, resource efficiency in construction and the embodied carbon in materials, especially composite blades and complex low carbon construction materials. The shift supports circular construction strategies, low embodied carbon materials and net zero whole life carbon targets, aligning with BREEAM, BREEAM v7 and wider expectations for environmental product declarations (EPDs). The strongest signal for decarbonising the built environment is clear: sustainable building practices must measure the carbon footprint of construction across design, use, maintenance and decommissioning.
