“We Live In The Coldest Period Of The Last 10.000 Years"

Jørgen Peder Steffensen is an Associate Professor at the University of Copenhagen and one of the world’s leading experts on ice cores. Using ice cores from sites in Greenland, he has been able to reconstruct temperatures there for the last 10000 years. So what are his conclusions?

  • Temperatures in Greenland were about 1.5 C warmer 1000 years ago than now.
  • It was perhaps 2.5 C warmer 4000 years ago.
  • The period around 1875, at the lowest point of the Little Ice Age, marked the coldest point in the last 10,000 years.
  • Other evidence from elsewhere in the Northern Hemisphere confirms this picture.

 

His final comment is particularly telling :-

 

I agree totally we have had a global temperature increase in the 20thC – but an increase from what? ..Probably an increase from the lowest point in the last 10,000 years.

We started to observe meteorology at the coldest point in the last 10,000 years.

 

Have a look at this short video of Professor Steffensen’s here.

 

The Professor’s findings are supported by other research such as this study.

    I would love the Prof. to be right, but don’t trawlers on the Dogger Bank regularly dredge up bits of Stone Age settlements? How does that fit into Prof. Steffensen’s theory?

      Sea levels were still much lower in those days as most of the glaciers left behind by the ice age were still slowly melting. Put simply, when the ice age ended, the glaciers did not suddenly melt in one go. It took thousands of years.

      The Neoglacial Advance from about 3000 BC is pretty well documented, e.g. “The most severe part of the best documented neoglacial period, especially in Europe and the North Atlantic, is termed the “Little Ice Age”.

      There’s a good analogy. Take a cube of ice out the freezer and leave it in a glass in a 70 F room for a few minutes.

      What happens? It starts to melt.

      Take the glass into a 60 F room. What happens? It continues to melt.

        It will continue to melt at slower rates even at 34 degree room temperature.
        Ice will ablate at even temperatures lower than freezing when cold dry air flows over the surface.
        While temperature is a reason for ice loss it is not the only one.
        To maintain a certain level of ice there needs to be equal amounts depleted and formed over time.
        The most constant thing we currently know is an atomic clock and ice conditions are extremely erratic compared to that.

    That is how I have understood history for years and the Chicken Little Brigade, with their fairy tales, have not convinced me otherwise.

    “The period around 1875, at the lowest point of the Little Ice Age, marked the coldest point in the last 10,000 years”

    That doesn’t seem to be very accurate, can someone please confirm it?
    I believe that the Maunder Minimum, 1645 – 1715 was the coldest point, by 1875, the LIA had ended.

      In England the Maunder Minimum seems to have marked the coldest episode, but after a warmer interval there several other descents into colder times, notably the 1740’s and 1880’s.

      Alaskan glaciers show the same pattern. 1880’s temps may have been slightly higher than the 17thC in England, but in Greenland they seem to have been a little bit lower.

      Check out this history of the LIA.

      Also the CET graph shows the sudden drop at that time.

      Quibble about dates, but nevertheless, the global temperature is still only just above that level.

      It is still dangerously cold compare to the optimum of earlier in the Holocene.

      Unfortunately the brief “slightly warm modern period” may not last too much longer. :-(

      Note, I suggest we adopt the anachronism “SWMP” for the brief molehill we are on.

      Use it wherever we can, especially on warmist alarmista blogs if you ever get the chance.

    Do you know anyone who has done this experiment, or has the results?
    If you have a tube of CO2 and you fire infrared light through it, what is the resulting blocking of infrared transmission (absorption and reradiation) per molecule or per gram of CO2 inside the tube?
    Then do the same thing with a tube full of CH4. How much more does CH4 absorb-reradiate than CO2? This was done crudely by John Tyndall 1859 with primitive equipment? What is the answer now that we have lot of very sophisticated equipment?
