The Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM) of Colombia has officially declared the El Niño climate phenomenon in progress [1].
This declaration serves as a critical warning for global agriculture and disaster management. Because El Niño alters precipitation and temperature patterns, it can trigger severe droughts in some regions while causing catastrophic flooding in others.
IDEAM said that the necessary conditions in the atmosphere and the Pacific Ocean have been met [1]. The agency expects the phenomenon to intensify toward the end of the year, potentially reaching a very strong phase [1].
Experts said that the impacts of El Niño are not uniform across the globe. The specific effects on any given region depend on the interaction between the warming of the central-eastern Pacific and various atmospheric circulation patterns [2]. These interactions ensure that different zones experience the phenomenon in distinct ways [2].
While the current phase began in 2024 [1], other meteorological projections suggest the phenomenon could return in 2026 [3]. Some forecasts indicate that these conditions could extend through 2027 [3].
There are further concerns regarding the magnitude of these events. Some reports suggest the possibility of a "super El Niño," which could potentially be the strongest such event seen in a century [4].
“The phenomenon could intensify toward the end of the year, potentially reaching a very strong phase.”
The official declaration by IDEAM highlights a volatile period for global climate stability. The contradiction between the 2024 start date and projections for a 2026 return suggests either a prolonged cycle or a series of rapid oscillations. If a 'super El Niño' occurs, the resulting disruption to food security and water availability could exceed the capacity of current regional mitigation strategies.
