Hot Times In Bathurst During The 19th Century

The Bathurst, NSW gaol kept temperature records from 1858 to 1983. Temperatures declined steadily during that period, as did the frequency of 100 degree days – which used to be quite common.

    I don’t imagine old thermometers are popular items among the ‘elite’ halls of academia.

    But, but… Those figures can’t be accurate, because they are based on measurements from mercury thermometers and not abstract modeling! You could at least used tree rings to give a little wiggle room in the figures.

    Although I find tree rings a bit dubious, I do find this paper on the bloom date for Kyoto cherry blossoms ( which have been tracked since the 9th century) pretty interesting. Note that it was written in 2008, so the paper is a bit dated in looking at the immediate declining trend.

      …The calibration and verification of March mean temperatures deduced from the phenological data in the instrumental period showed high accuracy (RMSE within 0.1 ° C) for estimation on the basis of normal climatic conditions, when smoothing was applied by local linear regression over 31-year time spans. The reconstructed March temperature series at Kyoto revealed some cold periods with temperatures of 4–5 ° C; ?3 ° C lower than present temperatures. These temperature declines coincided with periods of low activity in the long-term solar cycle, namely, the Wolf, Spoerer, Maunder, and Dalton minima. For the 18th and 19th centuries, the reconstructed temperature showed a climatic response delay of about 15 years in relation to the short-term sunspot cycle, which has a periodicity of about 11 years.…..

      HMMMMmmmm …A 15 year delay…. The Notch-Delay Solar Theory

        Or use the search on http://onlinelibrary.wiley.com/ for joc.1594.
        And yes, a darn good correlation to Dr. Evans’ The Notch-Delay Solar Theory

        Are you going to believe in primative thermometers read by even more primative humans or the wonderful models produced by leading climate scientists and computers that can do trillions of calculations in a second? I would go with the primative humans every time!

    How does the Bathurst temperature record compare to that of Sydney? It would be interesting to see how much UHI and fiddling has affected the “official” temperature record.

  4. Eliza says:

    Thats why ONLY rural records should be used to estimate global averages (surface anyway)

    • Gail Combs says:

      The problem is the definition of “rural” As in all Progressive definitions the word meaning morphs to fit the PC agenda.

    OT but snowing like crazy at Fernie Alpine resort … webcam here http://www.skifernie.com/conditions/mountain-cam-detail.aspx?image=2

    This is obviously the result of GLO-BULL warming and children just won’t know what this think of the past is /sarc/

      I’m thinking that tomorrow, when we look west from Calgary the mountains will be white….of course that will be adjusted…

    A tad cool around my neck of the woods. Where is spring?… please !!

    Bring on Summer, bring on the warming ! 🙂
