Ok, so why not just be specific? “On record” usually means since we started recording history , at least 5k years ago.
And have you looked into the records? satellite surface temps and high resolution recording have not been around for very long. 1880 methods were very crude and narrowly scoped.
and scientists edit the historical temperatures because of, and i hope you can see my eyeroll here "anomalous readings" - but they're overwhelmingly erroneous in only one direction. that's strange.

I'm a journalist who has published "highest/lowest on record" statistics tens, if not hundreds of times, and I've never heard of anyone thinking it means "since Herodotus" or anything like that.
