El Niño and Atlantic hurricanes

El Niño helps prevent hurricanes by creating stronger vertical wind shear. But it’s changing:

“It’s as if you had a big aquarium, with a Bunsen burner below it,” [Webster] says. “The heat causes a rising and sinking motion in the water. If you shift the position of the burner, you shift the motion of the water too.” The El Niño Modokis also result in reduced vertical wind shear, which promotes the creation of hurricanes.

This means more hurricanes.
