Well, as the article kind of tries to explain, some of the heat might actually hide down at the bottom of the Pacific over the next few years (La Niña). So, in terms of what we measure and what effects the temperature has on us directly, we might actually see some slightly cooler years coming up.

Basically, if you look at this diagram:

...you see that red years are peaks and blue years are troughs. We just came out of a red year, so we expect blue years to follow.

But yes, this is only a short breather. In a few years, the La Niñas will surpass this El Niño, and the next El Niño will be worse.
