Extreme temperatures over 100F or below 0F are both on the decline in the US
In 1936, more than 8% of temperature readings were either over 100F or below 0F, Recent years have been closer to 3%
Thank you for this intriguing report on climate changes over my own lifetime.
I suspect mankind’s selfishness and unwillingness to admit total powerlessness over the fountain of energy Copernicus discovered at the gravitational center of the solar system almost 500 years ago is the root of most social insanity.
I don’t understand the difference between the first two graphs. They are titled identically but have different values plotted on them.
I don’t know but I suspect the red line in the top one plots the mean while that in the lower plots the trend?
Read the titles again.
The first is summer days over 100F. The second is winter days below 0F.
All 3 graphs have different titles. First one is “above 100F” second is “below 0F” third is either “above 100F or below 0F”.
When you analyze the Tmin and Tmax on a seasonal basis, it is obvious that the rise in Tavg last century was largely due the urban heat islands. The pause is the result of the depletion of UHI warming in the land station record.
Off topic, but I just put a max/min thermometer out on my balcony, a nice north (no sunshine) exposure in Greenbelt, MD (about 10 miles NE of downtown Washington DC) on the 10th floor. Today National Airport had a max of 82 degrees. The other local airports, Dulles and BWI were 77. That is a ludicrous difference on a windy day, party cloudy, homogenous airmass. The difference in normal high temperatures is less than one degree.
My thermometer never got to 75. So what does that mean? National cheating big time and the others cheating small time? You simply cannot trust NWS temperature records.
Beware. It wouldn’t surprise me if the climate getting less extreme were cited as proof of “climate change”. Already, Ronald Bailey (of Reason Magazine) has found such proof in the supposed fact that the temperature difference between day and night is narrowing.
Children won’t know what hurricanes are.
The UN has instructed its propaganda team,
All the usual bad weather is now called ‘extreme’

Even the ultra-alarmist EPA’s data shows the 1930’s was the hottest decade with the most exteme heatwaves on record.

I would love to do a similar study with max and min daily dew points. Higher humidity moderates temperature extremes. Unfortunately historical dew point data is spotty.
Hifast check with Frank Lanser. He has the original lab books for many areas.
Also in the USA as of 1918 Willis Isbister Milham mentionin his text book Meteorology: A Text-book on the Weather, the Causes of Its Changes, and Weather Forecasting
there are 180 to 200 ‘regular weather stations ordinarily in the larger cities, 3600 to 4000 coop stations and 300 to 500 special stations. “The observations of temperature taken at a regular station are the real air temperature at 8am and 8pm, the highest and lowest temperatures of the preceding 12 hours, and a continuous thermograph record….” (Richard Freres thermograph) as well as other data.
