Climatologists warn of a new El Niño, which could cause global temperatures to reach record levels similar to those in 2024.

Climatologists have detected strong signals of the approaching El Niño phenomenon, after record gusts of wind from the western Pacific have pushed warm water eastward. This phenomenon is part of the El Niño-Southern Oscillation, a major factor in climate variability.

The last El Niño contributed to making 2024 the hottest year ever recorded, and models suggest a new event by the summer of 2026. El Niño releases oceanic heat into the atmosphere, raising global temperatures and affecting ecosystems. Its effects could peak in 2027, coinciding with the intensification of global warming, which could lead to record temperatures. Kevin Trenberth, a climate expert, emphasizes that each El Niño phenomenon amplifies the effects of global warming, having a significant impact on the planet's climate.
