Unprecedented Heatwaves Of 1911

January and February. 1911 brought record heat to the Southeast US.

May, 1911 brought precedent 100 degree temperatures to Maine and Quebec. May 22, 1911 brought the hottest May temperatures ever recorded in Maine, Vermont and New Hampshire.

This was followed by the hottest July 4th on record in the US, during a two week heatwave which killed thousands of people in New England. July 3rd, 1911 was the hottest day on record in New Hampshire.  July 4th, 1911 was the hottest day on record in Massachusetts and Vermont, and July 10, 1911 was the hottest day on record in Maine.

And Europe had a seventy day long heatwave which killed tens of thousands of people.

If climate science was an actual science, academics would want to understand the heat of 1911 – rather than try to make it disappear.

    In 1911 the CO2 proportion in the atmosphere was less than 300 parts per million – but it had risen by about 20 parts per million since the steady state 278ppm preindustrial level. Obviously that 22 ppm change made the climate gods angry so they decided to punish the evil people of the northern hemisphere by cursing them with heat. This was at a time when the AMO was largely negative but the PDO was positive. Is there anything causal in these correlations? Who can say?

    What is clear, though, is that such temperatures are not occurring now and have not in my lifetime – all while the proportion of CO2 has increased to above 400 parts per million. If one was actually going by observations – one might conclude that increased CO2 proportion might be decreasing the intensity of heat waves – likely through increases in vegetation and retention of water by plants. But that would imply that the grand poobahs of science might be barking up the wrong tree with regard to claims of impending climate doom — and that level of dissent is blasphemous.

      Preindustrial CO2 levels were cherrypicked.

      The notion of low pre-industrial CO2 atmospheric level, based on such poor knowledge, became a widely accepted Holy Grail of climate warming models. The modelers ignored the evidence from direct measurements of CO2 in atmospheric air indicating that in 19th century its average concentration was 335 ppmv (Figure 2). In Figure 2 encircled values show a biased selection of data used to demonstrate that in 19th century atmosphere the CO2 level was 292 ppmv. A study of stomatal frequency in fossil leaves from Holocene lake deposits in Denmark, showing that 9400 years ago CO2 atmospheric level was 333 ppmv, and 9600 years ago 348 ppmv, falsify the concept of stabilized and low CO2 air concentration until the advent of industrial revolution.

      I tried to post a graph in my first attempt at this post, and was blocked. If this comment posts, I will try again.

        The original notebooks and calculations by G.S. Callendar are in the Univeristy of East Anglia library. Reevaluating how 19th C CO2 levels were estimated may be a good historical research project for someone.

      Prof. Tim Ball and Prof. Zbigniew Jaworowski are heretics.

      Thank you.

    • Klaus Berger says:

      Wow! This is a very interesting study of 90.000 real measurements of CO2 from 1812 to 1960 using chemical methods. Not proxy data! Very few people know this. So happy that you and Tim Ball knows this!

    • Robertv says:

      “The average level for the ice core 2000-year record shown is approximately 265 ppm, while it is at least 300 ppm for the stomata record.”

      It must have been much higher, because otherwise agriculture and big (tropical)forests would not have been possible.
      The colder oceans during the little age age also absorbed large quantities so nature must have been producing vast amounts to compensate.

    The warming must be very severe now because as someone living in New England, I can attest to the fact that very many people up here are insane.
