This may seem like an innocuous statement, but this all actually encapsulates the Climate Bullshit perfectly. First, the government's statement:
The National Oceanic and Atmospheric Administration (NOAA) confirmed in a new report that the average temperature during this summer for the contiguous U.S. was hotter than the Dust Bowl in the 1930s.
The meteorological summer between June 1 to Sept. 1 averaged 74F for the U.S., or 2.6 degrees warmer than the long-term average. NOAA said, "this technically exceeds the record heat of the 1936 Dust Bowl Summer, but the difference is extremely small (less than 0.01 of a degree F)."
Remember the Dust Bowl? John Steinbeck and Henry Fonda sort of made it memorable:
1936 is the year of record heat in the United States. There's a reason that the midwest dried up and blew away that summer:
You want to see a real heat wave? Look at July 1936. Eleven States set high temperature records that stand to this day. That Wikipedia page is a little shifty on this, trying to hide the decline in record temperatures. You'll see an asterisk next to South Dakota, which the Wiki page says means Also on earlier date or dates in that state. So what was that earlier date for South Dakota? July 1936.
Oh, and three more States set high temperature records the next month, August 1936. That makes 14 out of the 50 States suffered record high temperatures in the summer of 1936. That's almost 30% of the States.
NOAA (the Fed.Gov's weather bureau) said that this summer was hotter than that. Oooooh kaaaaay. So riddle me this, WeatherMan: how many States set temperature records this summer? One. Washington State set a record high on June 29.
Not fourteen.
So how does NOAA get off saying that 2021 was hotter than 1936? Data adjustments:
The data have two components: the raw measurements themselves, and a set of adjustments.
Adjustments are made for a bunch of reasons: time of observation adjustments (you didn't take a reading at exactly the same time each day), environmental changes, weather station site relocations, urbanization, etc.
An interesting question is how much of the 20th century's temperature change is due to adjustments? As it turns out, the answer is all of it.
This chart shows the before-adjustment and after-adjustment temperatures for the 20th century, super imposed. All of the warming is due to adjustments, rather than raw data. Almost all of the adjustments are for readings after 1970.

Take a look at the blue (unadjusted) line in the middle of the chart. You know, at the peak. That's the Dust Bowl heat wave of 1936. Now look at the far right, how the data shift down (unadjusted) and up (adjusted).
How do you make 2021 hotter than 1936? Change the data. Older temperatures are adjusted downwards, and newer temperatures are adjusted upwards. Presto - Global Warming Climate Change Climate Emergency!
Now all of this is no doubt full of Science
® and all that, but if you get a whiff of bullshit, you're not the only one. You know what data don't get adjusted? Records. 1936 set 14 records, 2021 set only a single one.
That's some righteous Science
®, right there. But hey, no doubt Climate Scientists are well compensated for their work, if they produce the Approved Results.
