Antarctica was warmer one thousand years ago — and life was OK

Remember when polar amplification was the rage? So much for that theory

Antarctica is twice the size of the US or Australia. Buried 2 km deep under domes of snow, it holds 58 meters of global sea level to ransom. The IPCC have been predicting its demise-by-climate-change for a decade or two.

A new paper looks at 60 sites across Antarctica, considering everything from ice, lake and marine cores to peat and seal skins. They were particularly interested in the Medieval Warm Period, and researched back to 600AD.  During medieval times (1000-1200 AD) they estimate Antarctica as a whole was hotter than it is today.  Antarctica was even warmer still  — during the dark ages circa 700AD.

Feast your eyes on the decidedly not unprecedented modern tiny spike:

Luning, 2019, Graph, Antarctica Temperatures, AD 0 - 2000, MWP, LIA.

….

The little jaggy down after 2000 AD is real. While there was rapid warming across Antarctica from 1950-2000, in the last twenty years, that warming has stalled. Just another 14 million square kilometers that the models didn’t predict.

We already knew the Medieval Warm Period was a global phenomenon, thanks to hundreds of proxies, and 6,000 boreholes. But this new paper is a great addition.

With an awesome dedication to detail, the team put all the big oceanic and other factors into one big graph. It is nice to see them side by side so we can see the connections between them.

Main drivers of the multi-centennial scale climate variability appear to be the Southern Annular Mode (SAM) and El Niño-Southern Oscillation (ENSO) which are linked to solar activity changes by nonlinear dynamics. The MCA forms the final part of a long warm phase that dominated the first millennium CE

 

Looking at different parts of Antarctica some parts cooled while other parts warmed. Many of these “sea-sawing” pairs appear to be flexing as a dipole.

Somewhere is all this data are some answers that might help us figure out the climate.

A B S T R A C T
The Medieval Climate Anomaly (MCA) is a well-recognized climate perturbation in many parts of the world, with a core period of  1000–1200 CE. Here we are mapping the MCA across the Antarctic region based on the analysis of published palaeotemperature proxy data from 60 sites. In addition to the conventionally used ice core data, we are integrating temperature proxy records from marine and terrestrial sediment cores as well as radiocarbon ages of glacier moraines and elephant seal colonies. A generally warm MCA compared to the subsequent Little Ice Age (LIA) was found for the Subantarctic Islands south of the Antarctic Convergence, the Antarctic  Peninsula, Victoria Land and central West Antarctica. A somewhat less clear MCA warm signal was detected for the majority of East Antarctica. MCA cooling occurred in the Ross Ice Shelf region, and probably in the Weddell Sea and on Filchner-Ronne Ice Shelf.  Spatial distribution of MCA cooling and warming  follows modern dipole patterns, as reflected by areas of opposing temperature trends. Main drivers of the multi-centennial scale climate variability appear to be the Southern Annular Mode (SAM) and El Niño-Southern Oscillation (ENSO) which are linked to solar activity changes by nonlinear dynamics.

      Well yes, because Antarctica was not where it is now always! I have long held the (totally unproven) theory that penguins (or at least the distant ancestors) stayed with Antarctica as it moved southwards and evolved as it did so. That’s why some have such bonkers breeding grounds, because that’s where they were going millions of years before, when Antarctica was warm.

    Antarctic ice has been around for well over a million years through a dozen inter glacial periods whose temperatures were the same or higher as they are now. Even the worst case scenarios imagined by the IPCC/UNFCCC wouldn’t make a dent in the Antarctic ice.

      There is some discussion about the time that there has been an ice cap in Antarctica, with some claiming it has only been there for the last 25 million years. Other estimates run all the way back to 38 million years.
      In any case I think that it will still be there for a few years yet, and long after this nonsense about man-made global warming has been dismissed.

        Run with c. 38 million YA, Graeme. It’s more accurate.
        Antarctica and Australia were packed in more or less side by side into Gondwanaland, the southern half of Pangea. When they separated, Australia headed north (where it’s still going and rather quickly too), and Antarctica headed south. It would have been growing ice and snow on its southern flanks around then. It settled in and set about building its ice cap c. 33MYA.

        See this graph: note Antarctic glaciation and Antarctica melting …
        http://jonova.s3.amazonaws.com/graphs/lappi/65_Myr_Climate_Change_Rev.jpg

        A map of the Milky Way. Spiral Arm and Solar System rotation is clockwise. The Solar System takes c. 250 MY to orbit the Galactic Centre. Click on it to enlarge it (follow the mouse cursor to magnify a particular area more). Locate the solar system (to the left of SUN) You will note it’s on the outer trailing edge of the Orion Spur. That’s why it’s cold. Like: it’s the Quaternary Ice Age. Read Shaviv’s paper on Ice-Ages. It started when we crossed into the Orion Spur.

        The Sun and its Solar System is about 2.5 MY into Gould’s Belt where Cosmic Rays are fairly intense, hence the Quaternary Ice Age. We have at best guesstimate, about another 15 – 20 MY to cross the Orion Spur in. The far side of the spiral arm will have high levels of Cosmic Rays so we will probably ice over again then.

        Here’s a map of the Milky Way Galaxy. We’re looking at roughly 60 – 63 MY to cover each quadrant. While we are in Gould Belt, Antarctica is not going to melt. It will stay cold. Planet Earth is not going to warm much. If you look at the milky way galaxy again, to the right and up, you will see the Scutum – Centaurus Arm which the Solar System crossed during the Cretaceous. Yes, the Cretaceous had an ice age: that’s when the Dinosuars and Theropods invented feathers. Below the word ‘Arm’ there’s a clear area of space just before the Solar System entered the Sagittarius Arm. That corresponds nicely with the PETM – no Cosmic Rays, very sunny and very warm.

        The entry into the Sagittarius Arm caused cooling and there was lots more of that on the leading edge of the Sagittarius Arm as it the Solar System exited the arm and met the concentrated Cosmic Rays on its leading edge. About 30 MY to transit the Sagittarius arm. That was when Antarctica became King of the Underworld and really got to work building its Ice Cap.

        Cosmic Rays end up grouped by galactic magnetic fields — they run in streams and rivers. They do not form any amorphous bunch of atmosphere. So you will get warming — when GCRs go down a bit — and cooling as they rise. Antarctica is not going to melt any while we’re in Cosmic Ray rich territory. Yes, temps will go up and down just a bit but that’s noise. You could say, it’s going to be variably cool to cold for a while yet. However the idiots will run around like headless chooks and declare Klimate Krises.

        Light Entertainment:
        Supposedly there are alien spacecraft and alien bases hidden under the Antarctica Ice Cap..
        Yeah. Right.
        Have fun hunting for them … :-)

        Going back a little further, our leap into the Holocene may have been a reversal. Where is Sophocles?

        ‘Sites from Ecuador recorded two stable oblique reverse records with a large fluctuation far from the present GMF at ∼10.5 ka BP. The transitional virtual geomagnetic poles generally agree with those registered during the possible Pleistocene-Holocene excursion observed in other places of the planet.’

          The bipolar seesaw is related to D-O Events (glacial) and Bond Events (interglacial). Apparently it takes a couple of hundred years for Northern Hemisphere ocean waters to reach Antartica, a reflection of the Roman Warm Period perhaps.

              Judith Curry (Climate Etc) did a post on ocean heat transport and strolling through the comments I found this from Javier.

              ‘When summer insolation in the northern hemisphere decreased enough, about 6000 years ago, the seasonal insolation gradient changed, the Inter-Tropical Convergence Zone (ITCZ, the Earth’s climate equator) moved South, and the entire climate pattern of the planet got altered in what is known as the Mid-Holocene Transition.

              ‘Monsoons moved South and the northern 30° band dried up ending the African Humid Period and creating the Sahara desert. The planet moved from the Holocene Climatic Optimum to the Neoglaciation.’

          If the Younger Dryas cold snap was caused by a Big Rock from Space, then it could have had a short magnetic reversal. Ben Davidson documents it as a short one and the Mega Fauna Extinction could have been because of it.

          Plants don’t grow at all well when there is thick cloud (Svensmark effect) and lots of cold from lack of sunlight from masking by lots of dust and ejecta in the atmosphere. Plants die and the first flash of lightning sets off the fires. Starvation from lack of food and there’s a lot of life gone. Clovis man was no exception.

          The two Hiawatha Glacier craters need to be dated to set them in their place: either as cause or not.
          Then more evidence can be gathered. It’s not thorough enough yet so there are lots of doubting Thomases throwing ice water everywhere.

    “radiocarbon ages of glacier moraines”.

    Really, all scientists know about radio carbon dating. Old CO2 has no radioactive C14. Modern CO2 has a near constant level at one atom in a million million. C14 decays and when trapped the % left gives the age. Do you can date carbon atoms in bulk.

    Why don’t the same scientist apply this to the CO2 in the air and even CH4, methane? The total fossil carbon is under 5% and in 1956 was 2.1% even after two world wars, more than half way through the 20th century. Except the IPCC disagrees, without any proof.

    There is this continual suggestion without proof that CO2 and CH4 accumulate in the air

    In fact there is little fossil Carbon in in the air but that would be the end of the man made story, the end of man made Global Warming, the end of man made Climate Change, the end of windmills.

    I have written to Dr. Ed Berry suggesting the world needs a live % fossil CO2 meter. Any laboratory could maintain this with authority.
    Even the same for methane (CH4) a new attack by the Green blob. Then the ordinary person would understand instantly that there isn’t a man made problem.
    Then if there really is a Climate Emergency, what do they propose we do about it? Move the sun?

    As for Michael Mann’s Hockey Stick and his elimination of the Middle Ages warming, how does he live with himself when others are analysing what his graphs said didn’t happen. Nor the Little Ice Age which followed.

      True TdeF, ‘ radio carbon dating’ is used on biota which takes in carbon untill it dies, is the usual application.

      ‘Except the IPCC disagrees, without any proof’. Nothing that scamming organization says has any proof. When they have hijacked the ALL the world govts into the scam, which is looking like they have done a reasonable job at so far, then we will all have to watch out. Sooner the IPCC is abolished the better for humanity.

      “Even the same for methane (CH4) a new attack by the Green blob…”

      MCA: local or global?

      TdeF #6: As for Michael Mann’s Hockey Stick and his elimination of the Middle Ages warming, how does he live with himself when others are analysing what his graphs said didn’t happen. Nor the Little Ice Age which followed.

      I was wondering when someone might raise that point. The above authors, Lüning, Gałka, and Vahrenholt state in the opening sentence of their abstract: The Medieval Climate Anomaly (MCA) is a well-recognized climate perturbation in many parts of the world, with a core period of 1000–1200 CE. They dodge the global MCA, sticking to the line of settled politics, ‘local’ MCAs … (ironically not unlike global warming today, local not global).

      Taken one step further by the usual spin meisters of climatism: ‘Medieval Warm Period’ Wasn’t Global or Even All That Warm, Study Says, (Glacier maxima in Baffin Bay during the Medieval Warm Period coeval with Norse settlement) , the spine meisters chant (truncated):

      The tenth to thirteenth centuries, when temperatures in Europe were unusually warm, was also a time of relative cold in the western North Atlantic, according to a study published Friday in the journal Science Advances.

      The findings further undermine the notion of a global Medieval Warm Period that climate change denialists often hold up to support the false idea that today’s global warming is a result of natural, non-manmade causes. It also further debunks the belief that early Norse settlements in Greenland flourished and later folded because of changes in the region’s climate. “The Medieval Warm Period was certainly not a global event and probably didn’t even span the entire North Atlantic region,” said Nicolás Young, a glacial geologist at Columbia University who was the lead author of the study.

      “These glaciers were almost just as big during the Medieval Warm Period as they were during the Little Ice Age in the Baffin Bay and Labrador Sea region,” Young said. “It probably wasn’t all that warm during the Medieval Warm Period.”

      “If anyone is interested in the actual evidence this is going to be one more nail in the coffin of the Medieval Warm Period,” said Gifford Miller, a paleo climatologist at the University of Colorado.

      The findings, however, aren’t entirely new. They add to the results of numerous studies over the past two decades, including the conclusions of the United Nations Intergovernmental Panel on Climate Change.

      The previous work established that there was no globally uniform Medieval Warm Period, said Michael Mann, a climate scientist at Penn State University, in an email.

        That comment about the MCA being global caught my interest also. In recent comments about the Antartctic sea ice in The Australian, somebody claimed that the MWP wasn’t global. I responded saying that there are at least 200 reports from all around the would indicating that the MWP was global. The AGW crowd are trying very hard now to minimise the MWP as they have no answer to it being a natural event.

          To repeat: the above authors of the centre-piece of this thread, Lüning, Gałka, and Vahrenholt state in the opening sentence of their abstract: The Medieval Climate Anomaly (MCA) is a well-recognized climate perturbation in many parts of the world, with a core period of 1000–1200 CE.
          They dodge the global MCA, sticking to the line of settled politics, ‘local’ MCAs … (ironically not unlike global warming today, local not global).

          I made this point and cited a paper that highlighted it, also pointing out the irony that the globalist crowd think of their CAGW as global when in fact the evidence suggests it is local.

          No response from TdeF and a bunch of reflex reds, the proxy ad hom, no better than the usual globalist Left climatism venerating site. It would have been interesting and illuminating to have aired the salient literature, particularly since the centre piece of this post suggests a local MCA. Pretty weak.

    Just who is orchestrating this nonsense?

    Try contacting notable conspiratorial theorist Professor Stephan Lewandowsky over at Bristol University in the UK. He should be well placed to help out. After all, Bristol University has just declared a “climate emergency.”

    In a decision born out of a 500-signature strong petition and a letter to the vice chancellor signed by around 100 academics, the University of Bristol has become the first in the UK to declare a climate change emergency.

    The university made a similar promise back in 2015 and since 2005 they have been successful in reducing their carbon emissions by 27 per cent. This news comes following the Bristol City Council announcing plans for the city to become carbon neutral by 2030.

    Much of the academic World in general and the UK in particular have gone truly fcuk-wit. But then again, they are key doyens of the Lefts corporatist globalism UN Rainbow collective, wherein in all probability the answer you search for resides.

    I did some serious research on Antarctica climate, the article Try us out to help my study about local Antarctic effects of climate change are only part of the problem. Antarctica comprises two geologically distinct regions, East Antarctica and West Antarctica, separated by the great Trans-Antarctic Mountains but joined together by the all-encompassing ice sheet. The presence of the high ice sheet and the polar location make Antarctica a powerful heat sink that strongly affects the climate of the whole Earth. Furthermore, the annual sea ice cover around the continent, which seasonally reaches an area greater than that of the continent itself, modulates exchanges of heat, moisture, and gases between the atmosphere and ocean and, through salt rejection when it freezes, forces the formation of cold oceanic bottom waters that spread out under the world’s oceans. Alterations to this system will affect climate all over the planet.

    This data is not to scale. You can’t compared all these variables with different scales to a community that may not understand what to look for. It does a really good job at showing the that this is not the hottest point in history. Which is what the article wants. And although it’s happened before we are better connected now to report on the damage to wildlife, landscapes and how people living on islands would be affected. They didn’t have that communication back then so how do we know what damages did and didn’t happen?

    When will people realise that any CO2 reduction policy should also be seen in a longer-term context:

    · The modern short pulse of beneficial Global warming stopped 20 years ago and recent global temperatures are now stable or declining.
    · According to reliable Ice Core records the last millennium 1000 – 2000 AD was the coldest of our current Holocene interglacial and the world had already been cooling quite rapidly since before Roman times, in fact since ~1000 BC.
    · At 11,000 years old, our Holocene interglacial, responsible for all man-kind’s advances, from living in caves to microprocessors, is coming to its end.
    · The weather gets worse in colder times.
    · The world will very soon, (on a geological time scale), revert to a true glaciation, again eventually resulting in mile high ice sheets over New York.

    The prospect of even moving in a cooling direction is something to be truly scared about, both for the biosphere and for man-kind.

    Spending any effort, without true cost benefit analysis and full due diligence, let alone at GDP scale costs, trying to stop the UK’s 1% of something that has not been happening for 3 millennia seems monumentally stupid.

    Countless times I have made the observation that if CO2 levels for the last 10.000 years has been stable until just before the onset of the Industrial Revolution but there were periods such as MWP and RWP, then CO2 could not possibly be the driver for those rather wild temperature changes. Every time I said so I was attacked by innumerable commenters saying that this was a regional event only and does not stand for global changes. Now we know that this was horse dung and those warming events were global. This alone is enough to refute the entire Global Warming complex and all its models as garbage.
