One of the major tenets of the anthropogenic hypothesis of global warming is that the number of extremely hot days would increase, potentially causing catastrophic loss of life.
Such occurrences are the expected climate change manifestations from increasing CO2 emissions predicted by consensus experts and climate models.
But do these manifestations occur currently in a non-urban area with greater frequency than in years prior to modern global warming fears?
If CO2-driven global warming and climate change are as truly powerful and to be feared as many suggest, then the evidence of a greater frequency in the number of extreme hot days should be obvious.
As this article explains, there is a non-urban Japanese island (Hachijō Island) lying about 180 miles south of Tokyo in the Philippine Sea provides a long-term climate record of hot-day occurrences. (The island is administered by Tokyo.)
As in many countries, Japan uses the 30°C (86°F) minimum to designate an extreme 'hot day'.
The adjacent chart for the island identifies the number of 'hot and furious' periods going back to 1926 based on the 30°C criteria. For the 21st century specifically, including year 2000, there has been an average of 22.7 extreme hot days per year through 2017.
That's pretty high, especially when compared to the 1970's. But is that 22.7 number for the last 18 years unprecedented? Turns out the answer is 'no'.
The following 18-year periods, including 1929-1946, 1930-1947, 1931-1948, 1932-1949, 1933-1950, 1934-1951, 1935-1952, 1936-1953, 1937-1954, 1938-1955, 1939-1956, 1940-1957, 1941-1958, 1942-1959, 1943-1960, 1944-1961, and 1945-1962, had a higher average of hot days versus the 18-year period ending in 2017.
The 18-year span ending in 1958 had the absolute highest average count of extreme hot days - 25.8 days - per year.
What one can hypothesize from the above data and chart is that the huge growth of CO2 emissions has not produced the greater frequency of extreme hot days expected by experts. And also surmise that natural climate processes, for both the past and the present, are the responsible driver for periods with extreme hot weather events.
It should be noted that the modern count of extreme hot-day years has also been shown to be less in the modern U.S. era of high CO2 emissions when compared to the past.
This actual empirical evidence does refute the expert prediction that the frequency of extremely hot days across the globe would be a direct result of higher atmospheric CO2 levels. And although there certainly may well be regional areas of the world that have experienced a greater frequency - especially concrete/steel highly urbanized areas - there are indeed other areas of the world that have not.
