NOAA has officially confirmed the start of El Niño, which is set to worsen global warming from the burning of fossil fuels.

U.S. meteorologists say an El Nino has formed. That's the natural warming of parts of the Pacific that changes weather around the globe.

El Niño has officially begun, and it is forecast to intensify into a very strong or “Super” El Niño with major shifts in global weather patterns.
