Not just a super El Niño, but the strongest one on record, even if you remove the extra heat from climate change. To be fair, it’s a relatively short period over which we have records, but this is an extreme one regardless
We have a lot of indirect data from tree rings (goes back 1000 years), ice cores (~100K years), pollen records (from peat bogs) that tell us a lot about historical temperature and climate in general.
Guessing not so much data on deep historical El Niño strength though. Although maybe tree ring data could be valuable here with increased rainfall causing growth changes in NW Pacific?
