One Hundred Degree Days Are A Thing Of The Past …

This year (so far) is only the third year since 1895 to post no 100 degree temperatures in the Midwest.  The other two were 1928 and 1992 (after the eruption of Mt. Pinatubo.) The likelihood of 100 degree weather has plummeted over the past century.

The Midwest has had 26,461 100°F degree temperature on 2,629 days since 1895, but only thirty-four 100°F readings on fifteen days in the past seven years. There has been a massive decline in hot weather in the Midwest over the past century.

Meanwhile, climate alarmists say the exact opposite, because they have no interest in the truth and no shame about lying for money and power.

    Very interesting, Tony. What do the colors in the graph represent?

    • tonyheller says:

      Each color represents a different station. This is a huge amount of data, and making a legend for the 193 stations is not practical.

  2. David Reich says:

    Even Energy Sec Rick Perry is caving toward the alarmist view. Suggest you send him this and your other wonderful analytics.

  3. Steven Fraser says:

    Wow, Tony.. beautiful representations. They communicate your ponts very well.
    Congrats on the new tools.

    Each time alarmists propagate the “CAGW causes extrem events” scam in the media, fact checking shows that they are talking nonsense.

    Thanks Tony to systematically show the alarmism nonsense with very clear diagrams.

    The basic fact is that CO2 + WV mixture, as active gases in the mid to far infrared, helps transfer heat from warmer to colder areas of the atmosphere by radiative heat transfer, even if this heat transfer is weak (vertical heat transfer resulting in about 1 K cooling per day in the very lower atmosphere according to [Kondratyev 1969]).

    This is due to the emissivity of CO2 + WP which depends on temperature (and btw, also on total pressure, CO2 and WV partial pressures) :
    – higher emissivity with higher temperatures.

    The CO2 contribution to this radiative heat transfer is of about 3%, according to [Kondratyev 1969], perhaps a little more nowadays at 410 ppm.

    Thus, all other things being equal (solar activity, jet stream pattern, WV concentration, …), heatwaves would be more intense (higher temperatures) and would last more with less CO2.

    See for example :
    [Kondratyev 1969] : Radiation in the atmosphere,
    [Modest 2003] : Radiative heat transfer (second edition).
