El Nino Could Break Records: Strong and Global Impact Expected

The El Nino weather event has strengthened significantly in the last month, and it appears highly likely to be among the largest events recorded as it peaks between October and December. According to a statement from the Amerikan iklim tahmin merkezinden, the probability of experiencing a very strong El Nino during this period is calculated at 81 percent. The definition of a very strong El Nino is made as temperature increases of 2.0 degrees Celsius or above a specific index value. If such a scenario occurs, it will be among the greatest climate events in historical records dating back to 1950. Additionally, the probability of the event continuing until the first months of 2027 is estimated at 97 percent.

El Nino expert Tim Stockdale from the Avrupa Orta Vadeli Hava Tahminleri Merkezi stated that it would be a huge surprise if this event did not break a record. El Nino increases surface temperatures in the central and eastern parts of the equatorial Pasifik Okyanusu, triggering changes in atmospheric pressure and wind regimes worldwide. This situation leads to a rise in global average temperatures and causes unusual weather conditions in many regions. Experts warn that the effects of this year's event could be much more severe compared to the past. This situation poses serious risks, particularly in terms of agriculture and water resources.

Typical global effects of the El Nino event include a tendency for drought and desertification in Avustralya, and wetter winter seasons in Doğu Afrika and the southern Amerika Birleşik Devletleri. Climate scientist Isla Simpson from the Amerikan Ulusal Atmosfer Araştırmaları Merkezi stated that there is evidence from models that global warming has increased the variability of El Nino events. This raises the likelihood of seeing both larger El Nino and more severe La Nina events in the future. La Nina is known as the cooling phase of the El Nino-Güney Salınımı cycle, and it is thought that both phases of this cycle are becoming increasingly stronger. This dynamic structure makes seasonal weather forecasts more complex worldwide.

Within the Amerika Birleşik Devletleri, El Nino events generally have a drought-mitigating effect in certain regions like Kaliforniya, while causing drought in other regions. Although connections with the Avrupa continent are less clear and more uncertain, there is some evidence that El Nino could increase the likelihood of cold conditions emerging in Kuzey Avrupa during the later parts of the winter season. Simpson emphasized that while the expected classic El Nino impacts are likely to be seen, the situation could deviate from these due to random uncertainties in every event. This unpredictability creates challenges, particularly in sensitive sectors such as energy demand and agricultural production planning. Therefore, local governments need to prepare flexible and comprehensive emergency plans against such variable scenarios.

As the world prepares for a potentially record-breaking El Nino event, experts are urging governments and local communities to take urgent measures against possible impacts. Taking proactive steps in critical areas such as the agricultural sector, water reserves, and public health is of great importance to minimize potential losses. Early warning systems must be activated regarding issues such as food supply, drinking water security, and the spread of infectious diseases. Experts argue that resilience against such extreme weather events is the most fundamental way to cope with the increasingly evident impacts of climate change. Enhancing global cooperation and knowledge sharing will play a vital role in managing this process.
