Climate Central's analysis of 239 major U.S. cities from 1970 to 2025 found that 95% of these cities experienced an increase in 'mosquito disease days'—days with temperatures suitable for West Nile virus transmission. On average, these cities saw an increase of 18 days per year. The largest increases occurred in the Southeast, Northeast, and Northwest regions, with San Francisco, CA, seeing the highest increase of 52 days. The report also notes that while West Nile virus is the most common mosquito-borne disease in the U.S., warming is expanding the risk and range of other viruses like dengue and Zika, particularly along the Gulf Coast and into the Ohio Valley and Upper Midwest by 2050.

The study analyzes the Uruguayan industrial fishery sector from 1960 to 2013, identifying four phases: development, expansion, stabilization/diversification, and declining yields/market contraction. While the sector initially grew through the Argentine hake fishery and maintained a role as a net exporter, it currently faces a crisis characterized by decreasing yields of main target species and a rise in seafood imports, which now account for a third of domestic consumption. The findings suggest that a lack of a clear management framework and increasing fishing pressure have undermined the sector's resilience, necessitating a shift in the exploitation model.
