Our warming world is set to enter an El Niño period as early as May, with a high likelihood of southern North America experiencing supercharged temperatures.
One of the three phases of the natural El Niño-Southern Oscillation (ENSO) cycle in the Pacific Ocean, El Niño events occur every two to seven years, driving up sea surface temperatures across the Pacific Ocean and increasing global temperature. The last El Niño partially explains why 2024 was the hottest year on record.
