Rain, rain, go away. Is this current El Nino temporary, or part of the larger global climate change? Are El Ninos the new norm?

El Nino events happen in cycles with one occurring every 3 to 7 years. This is just another normal oscillation of the El Nino Southern Oscillation. There is some evidence to suggest that El Nino events have been occurring more frequently due to global warming, however the pattern is still that one occurs about every 5 years. All El Ninos so far have been temporary, and there is nothing to suggest that this one will be any different. In fact this El Nino has already begun to weaken.

As you can see from the above picture, the El Nino peaked in January and is now starting to return to normal. (Time is the y axis with the top being the oldest and the bottom being the newest measurments.)
