So what portion of
"
In a warming world, we should expect each year to be warmer than the last.
In an El -Nino year we should expect it to be much warmer."
Do you think is inaccurate?
I think very few people would disagree that the average temperature of Earth has increased over the last century,
so Earth is warming regardless of cause, and we would expect to see a series of ongoing warmer years.
Not all years will be warmer, but over a decade or two the baseline will increase.
In the world of signal processing there is something called Delta Code Modulation, which is a fancy way of looking at
how many integer units something moves from one time interval to the next.
In the case of temperature from a source like the GISS, it shows when El Nino events happen.

So if we start at May of 2023, it was 8 units higher than May of 2022,
June +15 units
July +24 units
Aug +24 units
Sept +58 units
Oct +37 units
Nov +70 units
Dec +55 units
Jan 2024 +34 units
We can see the El Nino Build and began to wane.
The other El Nino Years show similar results, but they are very much larger than the annual unit increases during non El Nino years.
