He says, for instance that, "This week's Niño3.4 SST anomaly of +1.0°C is at the threshold of a moderate-strength event. Another 0.5°C would push the event into the strong range, which was last observed in late 2009..." That conflates a present fact with pure speculation, because there is no assurance whatever that "[a]nother 0.5°C" is going to happen. He also hyperventilates about the "strong range" having been last seen in 2009-2010, but it should be pointed out that California's drought remained in full force during those years, which tends to debunk that said "strong range" produced much in the way of any effective El Nino weather pattern.
Yes, an El Nino pattern is beginning to show up, but lets save the cheerleading for the rainy season when something actually happens, if it does. In any case, I have a bit of a suspicion that global climate change is tossing all of the historical patterns out the window anyway.
