Little Ice Age — Climate Trend Milestone?

The Little Ice Age (LIA) received much attention by those who were affected by it.  Much was written about it, and most of that was forgotten again.


The IPCC (Intergovernmental Panel for Climate Change) discussed the Medieval Warm Period (from about 950 to about 1250) and the subsequent Little Ice Age (from about 1300 to about 1850) in section 7 of the IPCC 1 [1990] climate report, from which a Figure 7c became a somewhat-less-than-commonly-used image, at times presented as evidence of that both the Medieval Warm Period and the Little Ice Age had occurred.  The image does not quite match current standards for graphic presentations of data, is often not attributed to a specific author but was frequently attributed to Hubert H. Lamb,  Ph,D. (22 September 1913 – 28 June 1997), who had founded the Climatic Research Unit in 1972 in the School of Environmental Sciences at the University of East Anglia.  Hubert H. Lamb is considered by many to have been the father (or at least one of the fathers) of modern climate science.

Birth of the Climate Hockey-Stick Graph

The Medieval Warm Period and Little Ice Age regained prominence once more, lately, when Michael E. Mann produced a graph which showed a global temperature trend that glared by the absence of all evidence of not only the Little Ice Age but also of the Medieval Warm Period (MWP).

Michael E. Mann’s “Hockey-Stick Graph,” as it became known, caused many people in global-warming circles to love it, and many others — skeptics of the theory of catastrophic anthropogenic global warming (CAGW) — to write much about it, thereby to enable Michael E. Mann to acquire much infamy.  For instance, Michael E. Mann took Tim Ball, a venerable, retired Canadian Climate scientist, to court for making an off-hand, humorous remark about Michael E. Mann, for having stated that the latter should not be at Penn State (University) but in the state pen.  Michael E. Mann, for similar reasons, also sued Mark Steyn, an internationally renowned conservative journalist.  Mark Steyn was nevertheless not deterred by that.  Between court hearings of Michael E, Mann’s lawsuit against him, he penned a well-selling book about the affair of Michael E. Mann’s Hockey Stick graph.

The Medieval Warm Period had made all of the then known civilization thrive.  Amongst other things, it helped the emergence of a construction boom in Gothic cathedrals in Europe, motivated the Vikings to settle in Greenland, and it caused the emergence of a burgeoning sector of agriculture, involving vineyards, the growing and harvesting of grapes, and a wine production in England rivaling that of France.  Olive trees were cultivated in Germany, as stated in this,

Grapes were grown in England several hundred kilometers
north of their current limits of growth, and subtropical
flora such as fig trees and olive trees grew in regions
of Europe (northern Italy and parts of Germany) well
north of their current range. Geological evidence indicates
that mountain glaciers throughout Europe retreated
substantially at this time, relative to the glacial advances of
later centuries (Grove and Switsur, 1994)

Michael E. Mann deliberately obscured, in reports he produced later, that the Medieval Warm Period and Little Ice Age were of global significance, ignoring all evidence to the contrary and argued that they were merely local phenomena that had affected only Europe.

Debunking the Climate Hockey-Stick Graph

Steve McIntyre and Ross McKitrick, Ph,D, debunked the claims by Michael E, Mann that his arguments against the Medieval Warm Period and Little Ice Age had any scientific validity.  They demonstrated, furthermore, that Michael E. Mann had used dubious means for constructing the blade for his Hockey Stick Graph.  He had tacked late modern temperature readings to the shaft of his hockey stick that was based on calculations of temperature values constructed from estimates of temperature proxies such as the measurements of tree rings.  It is a scientific “no-no” to mix different sources of data in that manner, but that was not all.

Steve McIntyre and Ross McKitrick  analyzed all of it and published their findings in this:

Ross McKitrick

The data set of proxies of past climate used in Mann, Bradley and Hughes (1998, “MBH98” hereafter) for the estimation of temperatures from 1400 to 1980 contains collation errors, unjustifiable truncation or extrapolation of source data, obsolete data, geographical location errors, incorrect calculation of principal components and other quality control defects. We detail these errors and defects. We then apply MBH98 methodology to the construction of a Northern Hemisphere average temperature index for the 1400-1980 period, using corrected and updated source data. The major finding is that the values in the early 15th century exceed any values in the 20th century. The particular “hockey stick” shape derived in the MBH98 proxy construction – a temperature index that decreases slightly between the early 15th century and early 20th century and then increases dramatically up to 1980 — is primarily an artefact of poor data handling, obsolete data and incorrect calculation of principal components.

More at Steve McIntyre’s blog, and far more yet can be accessed through the linked index there.

Critics of Michael E. Mann and MBH98 were and are not so much upset by that proxies were used and that the interval was arbitrarily truncated, but that unreliable proxies were used wrongly and had tacked to them values calculated from actual temperature readings for the late 20th century, that it was not the result of a scientifically correct and trustworthy effort, and that it uses selected data and weighted it preferentially and unacceptably to strengthen the desired argument.  Moreover, it was noted by critics that data that did not fit the argument made by the report had been discarded or given less weight than preferred data.

Temperature measurements via thermometers was not done, globally and reliably, until after reliable thermometers and methods to use them spread, globally.  Proxies exist and are ever more often discovered and examined to yield data from which trustworthy estimates of what temperature trends were in ever more locations all over Earth, for when no thermometers existed. A collection of indicators of such studies can be examined at the website of CO2 Science, for example, identifying proxies that show evidence of the Medieval Warm Period and the Little Ice Age being found all over the Earth, in this:

Aftermath (added 2018 01 05):

Climate Hockey-Graph vs. objective science

Michael E. Mann on the left, Tim Ball on the right

Penn State climate scientist, Michael ‘hockey stick’ Mann commits contempt of court in the ‘climate science trial of the century.’ Prominent alarmist shockingly defies judge and refuses to surrender data for open court examination. Only possible outcome: Mann’s humiliation, defeat and likely criminal investigation in the U.S.

The defendant in the libel trial, the 79-year-old Canadian climatologist, Dr Tim Ball (above, right) is expected to instruct his British Columbia attorneys to trigger mandatory punitive court sanctions, including a ruling that Mann did act with criminal intent when using public funds to commit climate data fraud. Mann’s imminent defeat is set to send shock waves worldwide within the climate science community as the outcome will be both a legal and scientific vindication of U.S. President Donald Trump’s claims that climate scare stories are a “hoax.”….

Anyone who reads through the Chronology will be left with the firm impression that it is not so much warmth and warmer weather that kill, but that cold and cold climates are absolutely deadly and far more dangerous to human health, life and civilization.

A Cold Spell (2017 12 17 – 2018 01 2) and how it fits into the Scientific Climate Record Trend

Our severe cold spell (it is not really all that bad, as far as cold spells go) began 2017 12 17 and received first attention by the media and others on about Christmas Eve, when temperatures had fallen so low that no one could avoid noticing that it had become bitter cold and would remain so for some days in all or most of North America.  I summarized some of the comments I had posted on Facebook about that, elaborated on them and published that summary in the form of a blog posting (2017 12 29) at dads&things.

The Little Ice Age was merely one of the latest of such events (the current Modern Climate Optimum is neither all that remarkable nor optimal) in a very long string of similar ones that had contributed to a very gradual cooling of our globe during the last 9,000 years or so.  No one in the world knows why the long-term global cooling trend should stop now, reverse and turn colder (or much warmer yet), any time soon or at all.  We have not experienced statistically significant global warming for close to 30 years now. No one graduating from high school and entering college has ever seen or experienced any of it.

The Little Ice Age in the greater context — It cannot be erased.

The Little Ice Age in the greater context — It cannot be erased. There are simply too many places where the erasing would have to be done. The truth cannot remain hidden.

In the much longer term of the life of our globe, for the last 4.5 billion years, neither the Medieval Warm Period nor the Little Ice Age mean much, nor can they even be noticed in any graph of the long-term trends of either temperatures or atmospheric CO2 content, but it is unavoidable to notice that it not atmospheric CO2 content that drove the climate history of Earth.

P.S. A the time of writing this, 2017 12 31 13:40 hrs, the current temperature had warmed up considerably.  It was a relatively balmy -22.3°C, the sky cloudless and a bright blue, and the wind was very slight.  It was comfortable inside.   Let’s hope that the price of natural gas will not rise too much (ostensibly to cure us from being addicted to keeping our homes warm and comfortable, so as to allegedly have us help to pay for mitigating measures that will keep the globe from burning us to cinders).

  3. The Islamic Invasion and Conquest of the Roman Empire — Crime of Opportunity

    It happened when the time was right, after the population of the City of Rome had declined during a relatively short interval of about 500 years from its one million people down to about 70,000, and when the Roman Empire was down on its knees, reeling from the consequences of a climate gone wild after the Roman Warm Period that had helped to make the Roman Empire great was over. The Islamic conquest of the Western Roman Empire and of large parts of the Eastern Roman Empire began in 633 A.D. and took a mere 70 years. By 710 A.D. it was practically over, the Roman Empire was no more, and in 711 A.D. the Islamic Invasion began the conquest of Spain.

    If it is assumed that the temperature reconstruction from Greenland ice cores is representative of global temperature trends, then it appears that the decline of Rome began because of a down-turn in the climate trend shortly after 100 AD and accelerated after 400 AD.Holocene Epoch: Subatlantic Chronozone, last 2500 years

    Rome, City of, population history

    The Barbarian Invasions of the Roman Empire began in 300 AD and took place as follows,

    • The first phase, from 300 AD – 500 AD, put Germanic peoples in control of most areas of what was then the Western Roman Empire;
    • The second phase, from 500 AD – 700 AD saw Slavic tribes settling in central and eastern Europe (notably in eastern Magna Germania), gradually making it predominantly Slavic. Additionally, Turkic tribes such as the Avars became involved in this phase (more at Wikipedia, That was then followed by
    • The Islamic Invasions of the Middle East, Egypt, all of North Africa and eventually much of Europe began after the death of Mohammed (in 632 AD):
    – The first invasion of North Africa, ordered by Abdallah ibn Sa’d, commenced in 647 AD. It involved the conquest and occupation of Egypt, the Byzantine Exarchate of Africa, Tripolitania (in present-day Libya), much of North Africa, Damascus, the consolidation of the Muslim empire from the Aral Sea to the western border of Egypt, neighboring states, and attacks of Sicily and Anatolia (in Asia Minor) in 663 AD. See:
    – The second invasion of North Africa from 665 AD – to 689 AD brought about the founding of the Great Mosque of Kairouan (also known as the Mosque of Uqba) in 670 AD – the oldest and most important mosque in North Africa, in the city of Kairouan, Tunisia, to become the capital of the Islamic province of Ifriqiya, which would cover the coastal regions of today’s western Libya, Tunisia, and eastern Algeria; the establishment of the capitals of Fes and Morocco, and continued to the Atlantic and the Sahara; the conquest of the Maghreb (western North Africa) and the siege of the coastal city of Bugia as well as Tingi or Tangier, overwhelming what had once been the traditional Roman province of Mauretania Tingitana. (See
    – The third Islamic invasion of North Africa began in 692 AD and had by 700 AD bought about the occupation of most of North Africa (divided into three provinces: Egypt, Ifriqiya, and the Maghreb (modern Morocco) with its governor at Tangiers). By 709 AD, all of North Africa was under the control of the Arab caliphate. The next year, 711, Musa directed Tariq to invade Hispania.
    – The Umayyad conquest of Hispania was the initial expansion of the Umayyad Caliphate over Hispania, largely extending from 711 AD to 788 AD. The Islamic occupation of Spain did not end until 1491 AD. See:

    The Mediterranean was the heart and the major part of the circulatory system of the Roman Empire, the City of Rome its brain. The Islamic expansion and invasions put an end to the domination of the trade via the Mediterranean that the Roman Empire had depended on for its wealth and power. It appears that the Islamic conquest was perhaps not so much a struggle for superiority against the mighty Roman Empire as it was a taking of possession and plundering of an empire whose wealth and power had declined due to massive population losses on account of starvation brought on by the climate having changed much to the worse after the Roman Warm period.

    I am not a historian, but trying to understand what had brought the Roman Empire to it knees and made it lose its superiority gave me the impression that its decline happened primarily on account of starvation and disease caused by a climate change that was much to the worse because it turned much colder and brought about many adverse weather events that triggered serious, fatal harvest failures.

    The Barbarian and Islamic invasions occupied an empire whose people had died in large numbers, whose few survivors had fallen on hard times and were starving. Don’t take my word for it, but look for the evidence of that in “A Chronological Listing of Early Weather Events,” 7th Edition, by James A. Marusek.

    Given the accounts in the Chronology of the great suffering that the cooling of the climate had brought, one can only be amazed by the speed with which that decline happened. A warming climate, greater than that brought about by the Medieval Warm Period, and most definitely much greater yet than that which happened during the Modern Climate “Optimum”, had helped to make the Roman Empire great. A rapidly cooling climate motivated northern tribes (the Barbarians) to invade the suffering Roman Empire. Notice that they went South. With respect to what to to about the climate that had turned colder, they did the only thing they could, they voted with their feet and went South, where it was warmer.

    The Islamic invasions finished off and gobbled up what was left of the suffering remnants of the once great Roman Empire. Today we struggle to contemplate how all of that happened and why it happened so fast. There were few people left in the Roman Empire capable of writing it down and passing on to us the details of all of that. There are so few records left of it, that most of the story is guess-work and does little more than scratch the surface.

  4. Walter Schneider says:

    The scope for a discussion thread, anywhere, is set by the introductory posting of a given discussion thread (as it is for the FB discussion thread based on the blog posting above).

    A number of FB comments in the thread stated preferences for the good, old days, with those good, “old” days clearly falling outside of the scope of the Little Ice Age (which generally said to have occurred during the interval from about 1300 A.D. to about 1850 A.D.). Anyone having doubts about that needs to have a look at “A Chronological Listing of Early Weather Events,” 7th Edition, James A. Marusek, from which quotes are shown in the article that are being discussed in the related FB discussion thread. To save anyone the trouble of having to read the article to find those quotes, those quotes can be found directly at James A. Marusek’s Chronology.

    The years following after 1850 are no longer part of the LIA. Some of them are part of the the Modern Climate Optimum that began in about 1950, and we are still experiencing that, although the warming trend during it is slight and has not been statistically significant for the last 20 years. Mind you, the MCO is not as remarkably benign or benevolent as was the Medieval Warm Period (generally considered to have occurred during the interval from about 950 A.D. to about 1250 A.D.) During the MWP it was substantially warmer than it is now. (The second-last graph in the article permits to make an estimate of that temperatures during the MWP were about 1°C warmer than they have been during the Modern Climate Optimum.)

    There is nothing wrong with individuals stating what they perceive to have been “the good, old days,” from their personal perspectives, as long as the participants in the discussion thread do not lose sight of what the scope of this discussion thread is all about. It is about climate trends, not personal preferences that have little or nothing to do with the LIA, and that during lengthy down-turns in those trends the weather turned deadly cold (notwithstanding the odd hot summer and drought during the LIA). Examples of how severely people were affected by the LIA are included in the indicated article that is being discussed here.

    It does not follow that “the good, old days” as perceived through the various personal experiences of the commentors here negate the deadly experiences of the people who perished quite literally by the millions during the LIA.

    The deadly effects of the LIA were not always overlooked by people concerned about population trends (although warmists like Al Gore and cohort never mention, let alone stress, the far greater deadliness of cold climates and instead exaggerate the dangers of climates that warm by statistically insignificant amounts). For instance,

    »”The terrible political consequences of a war can be seen in the Thirty Years’ War. At the beginning of the war, the German people numbered more than 18 million, and by the end barely 3.5 million.[*] The consequences of these bloody losses are still not regained and compensated, for we lost the world-domination to which, at the beginning of the Thirty Years’ War, the German people seemed predestined. The disruption of our states lasted until 1870, that of our populace largely until 1933; the denominational disruption is not alleviated today.” — Martin Bormann, the personal secretary of Adolf Hitler
    [* The German-language original contains a typographical or scanning error that indicates “31/2 million”. Correctly, that must be 3.5 million. — WHS]«

    Martin Bormann was wrong in asserting or even only implying that the massive population losses in Germany during the 30-Years War (1618 to 1648 A.D.) were caused entirely by that war. Besides, Germany was not the only European country that had severe population losses during the time of that war. Some of those losses occured even in countries where there was no war during that time. However, some of those losses occurred on account of extremely cold temperatures. That caused widespread, deadly diseases and much deadly starvation. Still, it does not matter that Martin Bormann was wrong. His perceptions were biased, and that made him put a specific spin on things. Al Gore and his warmist collaborators are biased, too. They put their specific spin on things, and they sweep anything they don’t like under the carpet, Which makes them the more effective propagandists.

    It is of course difficult to estimate how much of the population loss was caused directly through war and how much through starvation and diseases that were the consequences of weather catastrophes (census records for that time are non-existent and at best of poor quality), but Indur M. Goklany, an expert and foremost authority on such issues, published credible statistics on what the population losses were throughout the world on account of natural catastrophes during the 1900 to 2010 interval. His information on that puts, at least in my mind and the minds of many others, all perceptions to rest that “the good, old days” during the last hundred or so years were all that good.
