The meteorological phenomenon El Niño peaked in December and is one of the five strongest ever recorded, announced today World Meteorological Organization, which predicts above-normal temperatures on land from March to May.

“Higher-than-normal temperatures are predicted in almost all zones of the earth between March and May,” the organization underlines.

El Niño is “gradually weakening, but will continue to have an impact on the global climate in the coming months, fueling heat trapped by human-made greenhouse gases,” clarifies the organization.

El Niño is a natural meteorological phenomenon, which causes a rise in temperature over a large part of the tropical Pacific Ocean, occurs every two to seven years and lasts from nine to 12 months.

This phenomenon changes the circulation of the atmosphere on a planetary scale and warms distant zones and, underlines the World Meteorological Organization, it manifests itself in the context of a climate that has been changed by human activities.

“There is about a 60% chance that El Niño will persist between March and May, and an 80% chance of seeing neutral conditions (neither El Niño nor La Niña) from April to June,” the agency said.

“Every month since June 2023 has set a new monthly temperature record – and 2023 was by far the hottest year on record.” says Celeste Saulo, the new secretary-general of the World Meteorological Organization.

“El Nino contributed to these record temperatures, but greenhouse gases that trap heat are undoubtedly the main culprit,” he said.

“Ocean surface temperatures in the equatorial Pacific clearly reflect El Niño. But sea surface temperatures in other parts of the world have been persistently and unusually high during the last 10 months,” recalls the meteorologist from Argentina, who has been the head of the organization since January.

“Sea surface temperature in January 2024 was by far the warmest January on record. It is worrying and cannot be explained solely by El Niño,” he warned.

The World Meteorological Organization says there is a chance of La Niña – which, unlike El Niño, causes temperatures to drop – to develop “later this year” after neutral conditions (neither) from April to in June.

However, the World Meteorological Organization estimates that the chances are currently too uncertain.
