I get the Hadley Cell expansion....its real..not debating it. But you only seem to mention the past three ENSO events that have not really acted as expected. The weak el nino event of 2014-2015 went about as expected..so didn't the 2017-2018 weak la nina. I don't think the 2016-2017 event was that out of the ordinary either. We still have modest ENSO events that do in fact behave in a traditional manner....
