How confident are you in that data and why?
I told you why.
Notice that several independent agencies came up with data that very closely agree.
In science, that's very strong confirmation.
I'm confident in what I posted because I know the location of the station and note the data for each day in two databases: Microsoft Access for work and LibreOffice Base for myself. And it's not following what we are told is happening.
Data has to be accurate. And it has to actually measure what you propose to measure. Your graph doesn't measure average world temperature. It appears to be a graph of the number of over-100 degree days in the United States. But it's not identified.
It's like you noticing that your house is getting warmer and warmer, but someone says that the back bedroom has more moments when it's much cooler.
So that's two data sets that disagreeing with what we're told.
Like your back bedroom disagreeing with the observation that the house as a whole is getting warmer. HVAC guys can tell you that there are a number of reasons for this. I had one room like that myself. It's important to make sure that your measurements are accurate
and that they measure that which you want to measure. BTW, here's the graph of average temperature in the United States, using presumably the same stations you're mentioning:
What area, exactly, does your graph represent?
It's been a relatively cool summer here in the Seattle area.
I have two sons living there. Both say it's been unusually hot last month.
Something's not lining up.
Yeah. First, your graph doesn't measure average temperature. And second, it appears to be for a local area. Can you show us the source, so we can check that out?
You can, of course, dismiss the data I've cited as not global mean
Not measuring the thing you propose to measure will produce errors, yes.
But then there's the problem of explaining why it's not following what we are told is a global trend, especially since we're dealing with more than one site.
Let's look at your measurements for the United States:
- The frequency of extremely hot days has increased since 1970 in 195 U.S. locations analyzed by Climate Central.
- About 71% (139) of these locations now experience at least 7 additional extremely hot days each year than in 1970.
Extremely hot days have become more frequent in 195 U.S. cities since 1970—putting health at risk more often.

Which is very significant.
We'll know that when we see the source and verify what area is measured. Even by your criteria, the U.S. is hotter than it was in the past.
