Northern Russia Summers 2.5 to 7.0C Warmer 7000 Years Ago

By Paul Homewood



More evidence of a much warmer climate during the mid Holocene in the Arctic:

    There you go again Homewood insisting on using data and facts. My climate scientist friends say they have a feeling that it was much colder then and they have a model and one tree ring to prove it!.

    ‘Northern Russia Summers 2.5 to 7.0C Warmer 7000 Years Ago’

    That is a huge range.

    Too many authors, too, giving me doubts as to its veracity, though there isn’t much there to screw up. “There were trees here in 7000 BC.” Hard to get that wrong.

    Date shown above is May 2000. Cambridge published 2017.

    Do we have anything more recent? Mr Paul, what triggered you to post a 21 year old article?

      Is there any reason why it is less accurate now?

      I doubt whether anybody is aware of it now

        Sky certainly isn’t – their latest climate hysteria section tonight (18.45?) showed Russians crying over the melting of the permafrost exposing mammoth bones and supposedly releasing vast amounts of “carbon”. Of course the permafrost was, well, permanent before AGW.

        You could have coupled that research paper with this more recent one.
        A Review of Abisko Case Study: Recent and Past Trees an Climates at the Arctic/Alpine Margin in Swedish Lapland
        Leif Kullman1*
        DOI: 10.9734/bpi/ciees/v2/7576D

        The conclusion contains this line …

        • According to megafossil records, mixed stands of birch and pine existed near 600 m above current treeline during the early Holocene. This implies 3.6°C warmer than present, in contrast to often advocated opinions that summer temperatures peaked in the middle Holocene. Adjusted for glacio-isostatic land uplift by c. 100 m since about 9500 cal. yr BP, the above figure has to be reduced by 0.6°C.

        About the author of this paper
        Leif Kullman
        Department of Ecology and Environmental Science, Umeå University, SE 901 87 Umeå, Sweden.

        He was born in 1948. He is a professor emeritus in physical geography and plant ecology at Umeå University, Sweden. His main scientific focus has been on climate-related landscape change on different temporal scales in high-mountain regions. Important achievements have concerned treeline responses to present century climate warming. In addititon, his results provide a fundamentally new view and paradigm shift of postglacial tree performance during early postglacial time

    Meanwhile, Putin is restricting the flow of gas to Europe, to pressure them to approve the Nordstream 2 pipeline:
    “Vladimir Putin is playing geopolitical hardball. He is quietly orchestrating a European gas supply crisis by restricting pipeline flows.

    The Kremlin-controlled group Gazprom has curtailed the summer supplies needed each year to rebuild depleted strategic inventories.”
    No one, but no one could possibly have seen this coming.

    It’s really weird that the Holocene Climatic Optimum is called a Climatic Optimum. It’s almost like the dreadful heat was, well, optimal or something.

    Data adjusters haven’t got round to that one yet.

    And before that the Eemian:

    “The prevailing Eemian climate was, on average, around 1 to 2 degrees Celsius (1.8 to 3.6 Fahrenheit) warmer than that of the Holocene. During the Eemian, the proportion of CO2 in the atmosphere was about 280 parts per million.”

    True interglacial are much warmer than now. We are still in recovery.
