As we learned from Chris Farley, El Niños can boost the odds of extreme weather (droughts, typhoons, heat waves) across much of the planet. But the most important thing about El Niño is that it is predictable, sometimes six months to a year in advance.

That’s an incredibly powerful tool, especially if you are one of the billions who live where El Niño tends to hit hardest—Asia and the Americas. If current forecasts stay on track, El Niño might end up being the biggest global weather story of 2014.
