  1. Also even if we are lucky and the Holocene does go long we are not out of the woods.

    “The lesson from the last interglacial “greenhouse” in the Bahamas is that the closing of that interval brought sea-level changes that were rapid and extreme. This has prompted the remark that between the greenhouse and the icehouse lies a climatic “madhouse”! — Neuman and Hearty (1996)


    However the one thing we can be sure of is the climate is NOT going to get ‘catastrophically warm’ for another 65K years.

  2. The earth is certainly not going to warm catastrophically for another 65 kyr. Only one interglacial , MIS-11, since the Mid-Pleistocene Transition has lasted longer than about half a precession cycle. Any hope that the Holocene would go long was shot down by Lisiecki and Raymo in 2005 in their rebuttal of Loutre and Berger, 2003. No more recent papers has rebutted Lisiecki and Raymo in the decade since then. Not that the MSM would bother telling us that.

    NOAA and WIKI ONLY report Berger’s earlier MODELED findings. They leave out Lisiecki & Raymo findings based on the real world.

    A Pliocene-Pleistocene stack of 57 globally distributed benthic D18O records
    Lisiecki & Raymo (2005)
    We present a 5.3-Myr stack (the ‘‘LR04’’ stack) of benthic d18O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm. This is the first benthic d18O stack composed of more than three records to extend beyond 850 ka,…

    Recent research has focused on MIS 11 as a possible analog for the present interglacial [e.g., Loutre and Berger, 2003; EPICA Community Members, 2004] because both occur during times of low eccentricity. The LR04 age model establishes that MIS 11 spans two precession cycles, with d18O values below 3.6% for 20 kyr, from 398 – 418 ka. In comparison, stages 9 and 5 remained below 3.6% for 13 and 12 kyr, respectively, and the Holocene interglacial has lasted 11 kyr so far. In the LR04 age model, the average LSR of 29 sites is the same from 398– 418 ka as from 250–650 ka; consequently, stage 11 is unlikely to be artificially stretched. However, the 21 June insolation minimum at 65°N during MIS 11 is only 489 W/m2, much less pronounced than the present minimum of 474 W/m2. In addition, current insolation values are not predicted to return to the high values of late MIS 11 for another 65 kyr. We propose that this effectively precludes a ‘‘double precession cycle’’ interglacial [e.g., Raymo, 1997] in the Holocene without human influence….

    A newer paper from the fall of 2012 Can we predict the duration of an interglacial? agrees with Lisiecki & Raymo and gives the calculated solar insolation values @ 65N on June 22 for several glacial inceptions:

    Current value – insolation = 479W m−2 (from that paper)

    MIS 7e – insolation = 463 W m−2,
    MIS 11c – insolation = 466 W m−2,
    MIS 13a – insolation = 500 W m−2,
    MIS 15a – insolation = 480 W m−2,
    MIS 17 – insolation = 477 W m−2

    Look at the amount of solar insolation it took to get out of the Wisconsin Ice Age and do not forget the Younger Dryas Cold Event aka The Big Freeze (ca. 12.9–11.6 ka) that flipped the earth back into the Ice Box despite the high insolation values.
    11,000 years ago…………… 523.16 Wm-2 peak insolation
    Wisconsin Ice age- Holocene transition
    12,000 years ago…………… 522.50 Wm-2

    In other words the earth barely made it out of the Ice Box at peak insolation and the earth has dropped an additional 47 Wm-2 since that peak and is now ONLY 12 Wm-2 above the bottom value for the Wisconsin Ice Age

    The Holocene interglacial is now 11,717 years old. That’s two centuries or so beyond half the present precession cycle (or 23,000/2=11,500). (Thank you Grand Solar Maximum) That solar max. was a once in 3,000 years event. SEE: A History of Solar Activity over Millennia

    And Politicians want to REDUCE the CO2 that might just keep us out of the Ice Box? Are they crazy or do they have a death wish!?

  3. If those who believe in Global Warming had a plausible explanation for the “Little Climatic Optimum” or Medieval Warming Epoch, (950-1300AD) I just might start believing them. When they show me evidence of the manmade CO2 emissions from the Vikings exploring the lush green fields of Greenland in their hydrocarbon burning SUVs, I’ll start believing they are on to something. Until then, they are just trying to get their hands into my wallet.

  4. LOL! Exxon performed climate science in the 70s and 80s and found the carbon emissions were causing global warming. Then they lied about it an this moron is repeating the lies.

    Now Exxon admits global warming is a fact and the GOP still can’t get their pointy heads around it.
