Greenland Ice Cores Show Temps Were Much Warmer 4,000 Years Ago

greenland ice core drillingJørgen Peder Steffensen is an ice core research professor at the Niels Bohr Institute at the University of Copenhagen. His team has reconstructed the last 10,000 years of Greenland’s climate history using ice core data.

It bears the fingerprints of climatic conditions of more than 120,000 years. [bold, links added]

When they removed the drill from the ice core, they leave a hole and insert a thermometer in the hole to map out the temperature through the three-kilometer ice sheet.

And that temperature, done within a thousandth-of-a-degree accuracy, the ice has not forgotten how cold or warm it was on the surface at the time the snow fell.

So using those temperatures, they reconstructed the temperatures of the last ten thousand years.

They found that if they go back about 4,000 years ago, they have temperatures that were two-and-a-half degrees warmer on average than today.

    Forwarded Message :

    Dear ScienceDaily Editor,

    I’ve coined a term  to
    explain :

    “CLIMATE Change”

    — Cyclical Solar-Effected Climate Change —

    Precession is an Earth-cycle of about 25,500
    years, which always-recurring Earth-cycle is
    billions of years old, where the tilt of the
    Earth rotates around its axis, causing CLIMATE
    Change—effecting shifts in Climate from
    glaciation-to-warming-and-back-again periods,
    NOT due to manmade pollution ( NOT due to
    “greenhouse gases” ).

    Anyone there know about that Solar-Cycle ?

    Co2 pollution – re IMPACT on CLIMATE – is
    akin to tossing a marble into an olympic-sized
    swimming pool.

    WARMISTS hope to reduce Co2 to ZERO!, even
    though Co2 is food for plants and trees and
    ocean flora !

    If you examine non-WARMIST scientists’ research,
    they gravely WARN us of starvation from a
    coming ( “minimum” ? ) glaciation period.

    It might be coming !

    Find and study the late Robert Felix’s book,
    “Not by Fire but by Ice”—a fine introduction to
    the above paragraphs ( at least, read his last page ).

    If you give it a fair/serious reading, you might be
    prompted to begin to finance Hydroponic Facilities
    across the U.S.

    Curiously, there is one in West Virginia that is
    massive!—and one near my property.

    Why? Do they serve in-the-know military interests ?

    Are you prepared—just in case ?

    -Rick

      Rick, To head off any negative comments on your otherwise important opinions, may i point out that there is a difference between the words affect and effect. I think you mean affect as in “solar-affected” and “affecting shifts”.
