EL AQUÍ Y AHORA DEL CAMBIO CLIMÁTICO

The briefing highlights how subtle changes in seasonal patterns—such as altered precipitation and temperature shifts—are creating immediate risks in the Americas. It provides case studies from Cuba, Puerto Rico, Brazil, and Argentina to demonstrate how these shifts increase soil erosion, extend the prevalence of dengue fever, and complicate dam management for energy and flood control. The document emphasizes that historical climate patterns are no longer reliable for planning and calls for integrated, flexible management strategies.

• In Cuba's Cuyaguateje mountain basin, a 16% increase in average annual rainfall between the 1960s (1560 mm) and the post-1980s period (1810 mm) has led to a 50% increase in the soil erosion rate, negatively impacting agricultural production and reservoir capacity due to sedimentation.
• Slight increases in precipitation during the dry season in Cuba, Puerto Rico, and southern Brazil have allowed Aedes aegypti mosquito populations to persist year-round, increasing the risk of dengue outbreaks and requiring a shift from annual to twelve-month surveillance.
• In southwest Argentina, rising temperatures during the cold season are increasing winter river flows and reducing snow storage in the Andes, which increases flood risks and challenges the economic management of hydroelectric dams designed based on obsolete seasonal patterns.
