El Niño Forming in the Pasifik May Lead to Historical Temperature Increases

The Dünya Meteoroloji Örgütü (WMO) announced that El Niño conditions have officially formed in the Pasifik Okyanusu and the weather event is predicted to turn into a strong event in a short time. WMO Genel Sekreteri Celeste Saulo stated that this development significantly increases the probability of drought and severe precipitation worldwide. Furthermore, it is emphasized that the risk of experiencing terrestrial and marine heat waves has also risen in many regions. According to the organization's Küresel Mevsimsel İklim Değerlendirmesi report, the effects of El Niño will peak between july and september. In the affected regions, sea surface temperature anomalies are expected to exceed 2 Santigrat degrees.

El Niño is a climate event that typically occurs once every two to seven years and is characterized by an abnormal rise in sea water temperatures in the eastern parts of the Pasifik Okyanusu. This oceanic change directly affects not only local weather but also global temperature averages, causing climatic fluctuations worldwide. As a result of increasing global temperatures, the likelihood of facing extreme weather events in many continents, including Avrupa, is significantly increasing. Although more variable weather conditions are expected in Avrupa seasons, the indirect impacts of El Niño on the continent are anticipated to be much broader. In this context, the Hollanda'daki IHE Delft Su Eğitimi Enstitüsü is issuing serious warnings that the event could threaten agriculture in regions from which Avrupa countries import food.

The greatest concern for food security is in tropical regions, where agriculture is already vulnerable to natural disasters. For example, in countries like Nikaragua, areas where staple foods such as corn and beans are grown have a highly fragile structure against adverse climate conditions. Extreme weather events that El Niño can trigger could further exacerbate existing environmental stress in these regions, leading to severe crop losses. This situation not only makes it difficult for the local population to access food but also risks depleting farmers' sources of income. Consequently, a decline in production in these agricultural regions has the potential to directly create pressure on food supply and prices in Avrupa.

The places where the devastating effects of El Niño will be felt first and most severely are the tropical belt. Looking at past El Niño events, it is seen that this period brought severe floods and flash floods in some regions. It has been recorded that the risk of flooding has seriously increased in vast geographies such as Güney Amerika, the southern regions of the Amerika Birleşik Devletleri, Doğu Afrika, and Orta Asya. Similarly, there are other geographies where the event brings drought; prolonged precipitation deficits and severe drought have been observed in large parts of Avustralya, the northern parts of Güney Amerika, and Asian countries like Endonezya. This polarized weather creates an unbalanced and heavy pressure on global ecosystems.

In light of all these data, officials and international organizations emphasize the importance of global preparedness and early warning systems. Developing and agriculture-based economies must put their emergency action plans into effect against potential disasters that El Niño will bring. Without proactive measures in areas such as water management, rural development, and crisis intervention, food insecurity could turn into a global humanitarian crisis. Such extreme weather events, whose frequency and severity increase alongside climate change, necessitate international cooperation and the establishment of resilient infrastructures. Meteorological developments in the coming months will clarify how destructive this global climate wave will be.
