Scientists Detect Huge Structure Under Ocean Fueling the Deadly Upcoming El Niño

Scientists detected a large warm Kelvin wave moving across the Pacific, with ocean temperatures far above average.

The warming could fuel a major El Niño, potentially approaching the severity of the 1997 event or other extreme episodes.

NOAA forecasters say the scale of this Pacific heat anomaly will be key to tracking climate risks in the months ahead.

A strong El Niño can worsen droughts, floods, and disease outbreaks, making the forecast important for public health and planning.
