The return of the El Niño phenomenon, often referred to as "the troublemaker of the Pacific," has been linked to unusual wind patterns and the movement of warm water in the Pacific Ocean. Experts believe this year's El Niño could be the strongest on record, earning it nicknames such as "Super El Niño" or "El Niño Godzilla." This event typically begins in spring, intensifies in autumn, and reaches its peak in December. Already, it has been connected to wildfires in Indonesia and the lack of fish for Peruvian fishermen. El Niño is a natural phenomenon that originates in the Pacific and is not directly linked to climate change, according to Myriam Khodri, a research director at the Laboratory of Oceanography and Climate. It is characterized by a temperature anomaly in a region of the central Pacific, occurring roughly every two to seven years. Normally, trade winds in the equatorial Pacific blow from east to west, pushing warm water toward Indonesia and Australia while bringing up cold, nutrient-rich water from the coasts of South America. During an El Niño event, this pattern weakens, causing warm water to accumulate in the central Pacific where it is usually cold. Several indicators suggest this year's El Niño will be particularly strong. Temperature anomalies in the central Pacific are 2.5°C above normal, and along the Peruvian coast, they are already 3°C higher. Heat is building up in the top 150 meters of the ocean, suggesting further warming in the coming months. Precipitation patterns also show that warm waters typically found in the western Pacific are now in the central region, increasing evaporation and rainfall. These temperature anomalies are significant, surpassing those seen during the strongest El Niño events since 1950 in the central Pacific. The consequences for countries near the Pacific include extreme rainfall and flooding on the Peruvian coast, a region that is usually a desert and highly vulnerable to such events. These are often developing countries with infrastructure that is not well-equipped to handle such extreme weather. In the coming months, the entire atmospheric circulation is expected to be disrupted by powerful convective columns in the central Pacific, which could affect weather patterns in Europe and the southern hemisphere. Europe is not the region where the direct effects of El Niño will be the strongest, as winter weather is more influenced by the Atlantic and the North Atlantic oscillation. However, due to the unusual nature of this event, there is increased vigilance and monitoring of forecasts. Europe is already 1.4°C warmer than the pre-industrial period, and while the impact on the European climate is uncertain, indirect effects are expected, particularly through the influence of climate change on global agricultural production. In Asia, issues with rice harvests are anticipated, and in West Africa, which relies heavily on rice imports, this could be problematic. In the Peruvian region, disruptions to fish stocks may also occur, indirectly affecting food security through global freight and transport disruptions. While El Niño is a natural phenomenon that has occurred throughout history, with very strong events recorded in the past, the current global warming linked to greenhouse gas emissions adds complexity. Although 2027 is expected to be a very hot year, it is not guaranteed. Research is ongoing about whether global warming will increase the intensity or frequency of El Niño events, and there is currently no consensus on this matter.
