Well, a “21st century version” of the 1957 pattern is theoretically possible if the stout -NPMM and warm EPAC/+SPMM continues unabated.
But it’s been decades since we’ve seen anything like that during a developing niño, so yeah, I’m always skeptical we will return to that until I see it happen.
The closest we came was 2012, actually. Lots of false alarms since the mid 1970s climate shift.
