Global Alert Issued as El Niño Intensifies and Extreme Weather Threatens Infrastructure

The World Meteorological Organization reports that El Niño is intensifying and is expected to become a strong episode between August and October 2026. This phenomenon involves an abnormal rise in sea surface temperatures in the central and eastern Pacific Ocean, which alters global atmospheric behavior and precipitation patterns. UN Secretary General António Guterres warned that the phenomenon is exacerbating a planet already suffering from heat domes and forest fires, attributing the crisis to the use of fossil fuels. The organization predicts above average temperatures for much of Africa, Southern Europe, the Arabian Peninsula, and large parts of South America.

In Argentina, the anticipation of El Niño has prompted preventive action in the northern zone of the Buenos Aires conurbano. Municipalities including Tigre, San Isidro, and San Fernando are coordinating hydraulic works, cleaning drains, and updating emergency protocols to prepare for potential flooding. Local officials have highlighted the vulnerability of these regions to heavy rains and are focusing on maintaining infrastructure such as storm drains and fire department equipment.

Beyond the Americas, extreme weather is posing risks to critical infrastructure in Europe. In Hungary, experts from the Budapest University of Technology and Economics have noted that extreme heat threatens the electricity grid. They point to the risk of thermal expansion in power lines, which can cause wires to sag and potentially lead to short circuits if vegetation is not properly maintained. This vulnerability was illustrated by a blackout in parts of the Balkans involving Bosnia and Herzegovina, Albania, Montenegro, and Croatia, which was triggered by inadequate vegetation management under power lines.
