The Latest Data on El Niño Is a Looming Nightmare

NOAA data suggests sea surface temperatures could climb to about 4.5°F above normal by November.

That raises the chance of a rare, unusually powerful El Niño event, possibly a "super" El Niño.

A stronger El Niño can worsen heat waves, flooding, drought, and other extreme weather worldwide.

The impacts could strain food supplies, infrastructure, public health, and national economies.
