Comment Pacific Decadal Oscillation (PDO) (Score 4, Informative) 235
The real story is a lot more complicated that TFA indicates. The new el nino is just starting and it's six months out of phase with the usual timing. So instead of starting six months late, it could just as well be seen as starting 6 months early in the next cycle. And more importantly, it is now combined with a phase change in the Pacific Decadal Oscillation (PDO). The two cycles combine to produce a much stronger warming effect. The negative PDO was responsible for the impression that warming had slowed. Now that it has reversed the warming will not just return to pre-1998 levels but will be much stronger. This could last for the next 10 to 15 years. Hopefully by then people with short attention spans will have realized that the planet is irrevocably getting hotter.
