The Midwest Just Had One Of Its Coolest Summers
Midwestern USHCN stations have recorded 17,772 June/July/August measurements over 100 degrees since 1895, including 2,624 in 1936 alone. This year there were only eight measurements over 100 degrees.
The frequency and intensity of hot summer afternoons in the Midwest have plummeted since the 19th century.
The New York Times claims the exact opposite because their job is to push propaganda – not report the news.
This is the wildly fraudulent New York Times’ graph for Harrisburg, Illinois, purporting to show the number of 90 degrees days.

And this is what the actual thermometer data looks like. The downward trend is the exact opposite of the New York Times’ graph.

Hi Tony,
Maybe it (less 100F days) is caused by modern farming practices. Corn has been discovered to improve the soil texture so there is less runoff. The narrower rows and higher plant density shade the soil so there is less evaporation from the soil. Yes, there is transpiration by the plants but that water has served its purpose and contributes to the the generally significant humidity during summer in the Midwest, so more dew forms during the nighttime. Thus, there is more water in the morning for the solar radiation to evaporate, which we know is a cooling process. And no till farming leaves more light colored plant material on the surface so more solar radiation is scattered, or reflected, back toward space instead of being absorbed by the soil surface.
So, I consider this cooling is man-caused.
Have a good day, Jerry

According to NOAA (Source – http://www.cpc.ncep.noaa.gov/products/tanal/temp_analyses.php ), summer temperatures were above normal for almost all of the country – including the Midwest.

Hi Bill,
You provide an opportunity to add to my previous comment where I forgot to call attention to the most obvious observation which is a result of modern farming methods. At places twice the energy of solar radiation has been converted into food energy as yields corn has increased to 300 bushel per acre relative to the previous 100 bushel per acre.
Now relative to your observation that the ‘average’ temperatures have increased while the number of days with temperatures of 100F have decreased. Maybe subtly, but I did propose that the humidity had increased which increased the amount of dew condensed during the nighttime.
In (https://principia-scientific.com/dr-jerry-l-krause-how-stupid-am-i/m) I drew attention to the observed fact that greater humidity results in warmer nighttime temperatures because the air temperature (which is the temperature to which you are probably referring) can never be lower than the atmosphere’s dew point temperature.
The average temperature of a day is commonly calculated by adding the maximum and minimum temperature of a day and dividing by 2. I believe if you study the maximum temperatures and minimums (actually measured temperatures) you will find that any increase in a day’s average temperature is due to an increase in the minimum temperature and not due to an increase in the maximum temperature. But I cannot refer you to where you might find the maximum temperatures of days during the summer being averaged and the minimum temperatures of days during the summer being averaged.
But I believe this is something which needs to be considered.
Have a good day, Jerry
