    Without you reminding us what went before, we’d all be running in circles screaming, The sky is falling! Seriously.

    The cold this last week produced some record low min and record low max temps. Pretty healthy shot of brutally cold weather that was almost as bad as late Jan/early Feb of 1996. Now comes the snow for the coming week here in N MN.

    Overview Summary from Duluth, MN NWS.
    In late January 2019, a historic arctic outbreak brought bitterly cold wind chills and record-breaking cold temperatures to the Midwest. Many schools and some businesses and government offices were closed for three days, with USPS mail delivery even suspended on Wednesday, January 30th due to extremely dangerous wind chills. The coldest temperatures occurred on the morning on January 31st when Cotton, MN recorded a low of -56, approaching the Minnesota state record low of -60 set back in 1996. The low of -56 at Cotton, MN was the coldest temperature recorded in the Lower 48 for this entire period of cold weather!

    I don’t think I’ve seen snow last as long in the shade and north slopes in Colorado as has happened this year. The summers and winters in the mid-west are essentially the same as the coldest periods of my youth. This equivalence of weather over so many years shows the folly of the warming belief.

    Where are the sources for these graphs?

  5. Fischbeck says:

    “All time record minimum temperatures in the US peaked around 1990” … 1890?

    Am I missing something?

    That’s interesting. during a cold AMO phase there are higher minimum’s and lower maximum’s, giving reduced variability. With cold AMO phase associated with stronger solar wind states, and the warm AMO phase with weaker solar wind:

    Considering that a reliable thermometer was not invented until after 1724 by physicist Daniel Gabriel Fahrenheit, who actually formulated the scale some countries still use, how can it be said that these figures are “all time” records? There are, to my knowledge, NO actual records of temperature before the Fahrenheit thermometer came into general use, probably in the early 1800s. Also, considering the constant changes in orbit of the Earth around the Sun, and changes in the inclination of the Earth to the Sun due to it’s wobble around the poles, the period of which is, according to Milankovitch around 10 to 15 thousand years, no one on Earth could possibly know, due to lack of writing ability and thermometers in those days, just what figures are available to make records from. Any records quoted now are of very little to no use!
