Against the backdrop of a surge in pure disasters worldwide, a Turkish environmentalist has launched into a analysis research lately spotlighting the results of El Nino, a climatic phenomenon infamous for elevating temperatures throughout the globe and inflicting a cascade of pure disasters by altering precipitation patterns, air temperatures and wind currents.
Professor Hasan Tatlı, a lecturer within the Department of Geography at Çanakkale 18 Mart University (ÇOMÜ) Faculty of Humanities and Social Sciences, revealed that El Nino, a Spanish time period which means “the son,” started to manifest its affect throughout this yr’s summer time season. This phenomenon, originating within the Pacific Ocean, initially impacts coastal areas earlier than inducing vital climatic shifts on a world scale.
Discussing the ramifications of El Nino, Tatlı informed Anadolu Agency (AA) that the polar jet stream winds within the northern United States usually deliver precipitation to their efficient areas. However, throughout an El Nino occasion, these winds veer southward, lose their vigor over beforehand rain-soaked areas, and finally set off droughts that may result in devastating forest fires. Tatlı underscored that there isn’t a scientific proof suggesting El Nino straight impacts Türkiye and its environment; as an alternative, its major impression is felt in Central Asia, the Horn of Africa and northeastern Australia.
El Nino not solely elevates sea floor temperatures within the jap Pacific Ocean but additionally results in local weather change worldwide, Tatlı famous. He defined: “El Nino raises temperatures more than the norm because it reverses the cycle, creating what we call a temperature anomaly. Warming water and increased evaporation in one region do not guarantee precipitation there. There exists a phenomenon known as horizontal transport, where water vapor capable of generating precipitation can be transported to other regions, leading to rainfall there.”
Tatlı emphasised that areas equivalent to Australia and Indonesia, which generally expertise wet seasons, might encounter drought circumstances throughout El Nino intervals. He clarified that for precipitation to happen, an upward motion within the environment is required. However, throughout El Nino occasions, a counterproductive downward movement happens, leading to rainfall deficits. Furthermore, El Nino can stimulate tropical cyclone exercise, probably intensifying hurricane seasons within the Atlantic Ocean.
Under regular local weather circumstances, commerce winds transport heat seawater from South America to Asia, resulting in the upwelling of nutrient-rich deep ocean waters. Tatlı cautioned that El Nino can disrupt this delicate stability, inflicting a lack of vitamins and biodiversity. Rising sea temperatures also can render sure marine organisms unable to face up to the warmth, resulting in mortality or migration.
Tatlı highlighted the potential impression on aquatic species’ feeding habits, noting that some organisms might battle to entry meals sources, probably resulting in adjustments in species variety. Additionally, he warned that coral reefs, extremely delicate to sea temperature fluctuations, are susceptible to dying because of rising temperatures, extreme rainfall or drought. These adjustments can impression agriculture, leading to diminished water sources, crop losses and soil erosion.
The pressing must curb greenhouse fuel emissions and local weather change administration was underscored by Tatlı, who emphasised the significance of decreasing fossil gasoline utilization, transitioning to scrub vitality sources and enhancing vitality effectivity. With drought rating because the main pure catastrophe globally, and earthquakes taking priority in Türkiye, every area faces distinctive challenges. Tatlı pressured the significance of creating early warning programs to observe and predict El Nino occasions, permitting communities to arrange for potential impacts equivalent to drought, floods and excessive warmth.
