If El Nino is a difference between average ocean temperatures and the SST at particular place/time, then as ocean temperatures rise in response to global warming the absolute temperature/ heat content bar for calling an El Nino must rise. And, a moderate El Nino of today reflects more ocean basin heat than a moderate El Nino of 40 years ago? If, on an absolute basis, modern El Ninos are driven by larger heat pools then El Ninos of the past, do modern El Ninos have more effect on the global climate? Or, is everything relative, and they have no more effect because everything else is warmer. Or, do the non-linear effects of water vapor dominate, and more water vapor in the air changes everything?
