I don't recall reading any claims here of a "super El Niño," just a discussion of the range of possible outcomes, with uncertainty for each outcome. As Emily discussed and as shown here, the probability of a strong (but not necessarily "super") El Niño rises above 50% for next fall and winter, where "strong" is defined as Niño-3.4 index values exceeding 1.5C. For context, the highest seasonal Niño-3.4 index values have reached around 2.5C in the strongest El Niños.
