US meteorologists declared the onset of El Niño, a climate phenomenon that raises global temperatures. The event is expected to intensify weather extremes worldwide.
The Declaration
The US National Oceanic and Atmospheric Administration (NOAA) announced the arrival of El Niño conditions in the Pacific Ocean. The agency noted that sea surface temperatures have risen 0.5°C above the threshold. This marks the first El Niño since 2019.
Global Temperature Impact
El Niño typically adds 0.1-0.2°C to global average temperatures, compounding long-term warming. The World Meteorological Organization (WMO) warned that 2024 could become the hottest year on record. Previous El Niño events have triggered droughts in Southeast Asia and floods in South America.
What's Next
NOAA will monitor the phenomenon's strength over the coming months. It remains unclear whether this El Niño will be moderate or severe, and how quickly its effects will unfold.
