EMPIRICAL PROVE OF RISING GLOBAL TEMPERATURES
(Revised on August 19, 2026)


For a few years, I have been using several instruments to measure temperatures. And two of them store the highest and the lowest temperatures of each day. And I have been writing down that data for a few years. Therefore, I am showing here, empirical evidence, that average temperatures are rising every year. And that is a fact.

NOTE: My temperature readings are not like the ones you see in the news, because I am next to the everglades,  about 20 miles from the coast line. And my outdoor temperature sensors are not on top of a building, nor near the coast line, where a gentle breeze from the ocean will lower the temperature readings.
 
Here is a comparison between the average high and average low temperatures of July 2019 and July 2023 :
(NOTE: all temperature values are in degrees Fahrenheit, because the USA and Liberia are the only two countries in the world that have not, officially, adopted the metric system of measurement).
 
                       Average         Average        Total
                     Low Temp     High Temp   Average
July 2023       78.5                105.2               91.85
July 2019       75.8                100.2               88
                     ---------               ---------            -----------
 Difference     2.7                     5                   3.85      Increase in 4 years

The data clearly shows that in 4 years (2019-2023):
Average LOW Temperature has increased by 2.7 degrees.
Average HIGH Temperature has increased by 5 degrees.
Total Average Temperature has increased by 3.85 degrees.
 
The daily temperatures, used to compute the above averages, were measured in the same place (about 20 miles from the Florida coast line), by the same instruments, and can be seen in spread sheet format in the following links:

JULY 2019 TEMPERATURES
JULY 2023 TEMPERATURES

Sometimes, when the temperature is so high, I take a photograph of one of the temperature readers, so I can have empirical data (prove) that such temperature was measured.
Here is a sample of such photos:



So, I have, empirically and rationally, proved that temperatures ARE rising. 

UPDATE:
This year (2026), I noticed that 2023 had the highest average temperatures and the highest temperature recorded.
Here is the latest temperature data, in spread sheet format, for June, July, and August of 2019, 2023, 2025, and 2026 (August 2026 is not over yet, I will add that data once available).

 

The chart bellow, shows how the high temperature records are increasing while the cold temperature records are decreasing.



Anyone who, by now, does not believe that global temperatures are rising, is neither a rationalist nor an empiricist. He, or she, must be in denial or very gullible about the misinformation and/or disinformation spread by those who are hiding the truth about global warming and climate change.
