Global temps peaked in 1998 in that stretch. They didn't cleanly surpass 1998 levels until 2005, well after the demise of the Niña event. 1999 and 2000 were each about 0.2C colder globally than 1998, though still slightly warmer than 1996. The only significant Niño year in the last 50 years that has coincided with a colder global temperature anomaly was 1992, and that was probably entirely due to Pinatubo.

I think the excess death tally from the 2021 event was around 1400.

Nice run per the ECMWF... consistent warmth rather heat spikes and then big crashes. Also lovely day at home with scenic sky of high clouds. Looks like nice weather continues after we get home.

Luckily for you, but not so much for the West. Some of us rather enjoyed the -PDO/-ENSO stretch.

Kind of figured we were going to pay for the warm spring at some point. Hopefully there is some more consistent warmth by the second part of May. I forgot how cool last May was. I do recall having a low in the 30s at the beginning of June.
