That's what they did after 1998, when we had an especially strong El Niño. Records were broken, and I saw a lot of graphs pointing out downward temperature trends. Those graphs never started in 1997 or 1999 or any other year, but always 1998.
In fact, I was already starting to see similar graphs starting at the last El Niño from 2019, and noting that 2022 was merely the sixth warmest year ever. By that time 1998 had dropped out of the top 10.
That cherry was no longer available for picking, but as long as the temperature doesn't monotonically go up, there will always be some other year to be "no warming since..." All they have to do is get through this year, probably with the line "weather isn't the same as climate".
So I appreciate the experts' new warning, but I wish I knew what to do with that information. All reasonable tactics of persuasion have long since failed. Maybe we'll get lucky: the heat dome this year just happens to cover a lot of people with an ideological predisposition to doubt climate change, and might just change a few minds even though it really is due to weather than climate.
