Between 1900 and 2022, there have been 35 El Nino warming events recorded. An examination of the temperature rise caused by those events has shown that they occurred within the range of 0.029 – 0.54 Deg. C, with those of longer duration generally having the higher temperatures. Their median maximum temperature value was 0.29 Deg. C, and their average value was 0.26 Deg. C.
In all but four instances, they were ended because of the injection of cooling volcanic Sulfur Dioxide (SO2) aerosols into the stratosphere by a VEI4, or larger, volcanic eruption. The exceptions were due to increased levels of industrial SO2 aerosol emissions.
This information can be used to judge whether future El Ninos fall within the normal range, or not, etc.
