The Medieval Warming Period Was 3-Degrees Warmer Than 2014

  • “For someone to think that 1998 or 2010, or even 2014 are the warmest years… you have to be smoking something.” ~ RPT [Me]

TheGreatGlobalWarmingSwindle

Here are a few evidences — of the many — that indicate it was much warmer in the past and that 2014 wasn’t even near the warmest year [even assuming this to be true!]. The first piece of evidence to show is a recent studies dealing with giant clams.

CLAMS

Clams hold pearls and insights to Earth’s climate history. Two recent studies examining clams and coral samples in the South China Sea suggest the climate was warmer during the Medieval period than during modern times.

Two studies out of the Chinese Academy of Sciences found that the climate was warmer in the Roman and Medieval warm periods than today, despite much lower atmospheric concentrations of carbon dioxide.

“This new paper adds further material to the substantial body of real-world proxy evidence establishing that today’s global temperature is within natural ranges of past changes,” Dr. Hong Yan with the Institute of Earth Environment at the Chinese Academy of Sciences.

Studying giant clams and coral reefs, scientists were able to reconstruct sea surface temperature changes going back 2,500 years. What the clam and coral data show is the Roman and Medieval warming periods impacted East Asia and the western Pacific. The study provides further evidence against the theory that there was little global temperature variation until the 20th century.

Both Chinese studies provide evidence for what is called the Medieval Warm Period, which took place during the late Roman Empire and Middle Ages. The period preceded a time of cooling known as the Little Ice Age…..

More from the Chinese Academy of Sciences via Watts Up With That:

Two recent papers, one is in Earth-Science Reviews and the other is in Chinese Science Bulletin, have studied key chemical contents in micro-drilled giant clams shells and coral samples to demonstrate that in the South China Sea the warm period of the Middle Ages was warmer than the present.

The scientists examined surveys of the ratio of strontium to calcium content and heavy oxygen isotopes, both are sensitive recorders of sea surface temperatures past and present. The aragonite bicarbonate of the Tridacna gigas clam-shell is so fine-grained that daily growth-lines are exposed by micro-drilling with an exceptionally fine drill-bit, allowing an exceptionally detailed time-series of sea-temperature changes to be compiled – a feat of detection worthy of Sherlock Holmes himself.

By using overlaps between successive generations of giant clams and corals, the three scientists – Hong Yan of the Institute of Earth Environment, Chinese Academy of Sciences, Willie Soon of the Harvard-Smithsonian Center for Astrophysics and Yuhong Wang of Fudan University, Shanghai – reconstructed a record of sea-surface temperature changes going back 2500 years.

The Roman and Mediaeval Warm Periods both showed up prominently in the western Pacific and East Asia. Sea surface temperatures varied considerably over the 2500-year period.

Changing patterns of winter and summer temperature variation were also detected, disproving the notion that until the warming of the 20th century there had been little change in global temperatures for at least 1000 years, and confirming that – at least in the South China Sea – there is nothing exceptional about today’s temperatures.

Dr. Yan said: “This new paper adds further material to the substantial body of real-world proxy evidence establishing that today’s global temperature is within natural ranges of past changes.”  Dr. Soon added: “The UN’s climate panel should never have trusted the claim that the medieval warm period was mainly a European phenomenon. It was clearly warm in South China Sea too.”

NORTHWEST PASSAGE

Another example is that in the the 1500’s till the late 1800’s passages that are now iced over allowed for what is termed as the Northwest PassageExxon or cars weren’t around then?

“If you are like me and bit foggy on the Northwest Passage, here is a five cent refresher. The British coined the term Northwest Passage for the potential northern oceanic pass that would allow vessels to move between the Atlantic and Pacific Oceans. The earliest explorations for the fabled passage were by Cortes in 1539. The late 1500’s were marked by British explorers, Martin Frobisher, Humphrey Gilbert, and John Davis. Several expeditions followed, all with little success of finding the passage but tempered by the acquisition of new lands. Some attempts lead to deaths of entire crews. Notable of these is the Sir John Franklin expedition in which all of the crew members were lost to starvation, scurvy, cannibalism, and lead poisoning from food sealed in tins. The first to transverse the Northwest Passage was Sir Robert McClure using a combination of both sledge and ship. Ironically this was done during the search for Franklin’s team in which McClure’s own ship became trapped in the ice for three winters. The passage was finally conquered entirely by sea by the Norwegian Amundsen in 1906.”


UPDATE

New York Times Mentions by Mistake


(WESTERN JOURNAL) The New York Times ran an editorial Saturday about the effect climate change had on discovering the Northwest Passage that appears to contradict claims the Arctic ice is melting at cataclysmic rates.

Global warming would have helped famed fur trader Alexander Mackenzie discover a Northwest Passage connecting North America to China, according to a NYT editorial from author Brian Castner.

His piece contains one significant caveat: Mackenzie’s 1789 trip happened during an era of above normal ice packed in the North that occurred before widespread fossil fuel use.

“Mackenzie paddled during the Little Ice Age, a few centuries of below-normal cold,” Castner wrote before noting Mackenzie’s failed attempt probably would have been successful had temperatures been at normal ranges.

“If he had undertaken his trip during average conditions, or at our current global temperatures, he would not have been stopped by ice,” he added.

“If the ocean hadn’t been icebound, would the fur trade have followed him down the river to China?

Would a summer Deh Cho have been Canada’s own Mississippi River? Would settlers have wagoned in, a northern Oregon Trail?”

VIKINGS

Another hint are the Vikings and how they flourished.

Here are some great excerpts from a book[s] on the subject that include Icelandic and Greenlandic Vikings:

  • The warm climate during the MWP [Medieval Warming Period] allowed this great migration to flourish. Drift ice posed the greatest hazard to sailors but reports of drift ice in old records do not appear until the thirteenth century (Bryson, 1977.)
  • The Norse peoples traveled to Iceland for a variety of reasons including a search for more land and resources to satisfy a growing population and to escape raiders and harsh rulers. One force behind the movement to Iceland in the ninth century was the ruthlessness of Harald Fairhair, a Norwegian King (Bryson, 1977.)
  • Vikings travelling to Iceland from Norway during the MWP were probably encouraged by the sight of pastures with sedges and grasses and dwarf woodlands of birch and willow resembling those at home.
  • Animal bones and other materials collected from archaeological sites reveal Icelandic Vikings had large farmsteads with dairy cattle (a source of meat), pigs, and sheep and goats (for wool, hair, milk, and meat.) Farmsteads also had ample pastures and fields of barley used for the making of beer and these farms were located near bird cliffs (providing meat, eggs, and eiderdown) and inshore fishing grounds. Fishing was primarily done with hand lines or from small boats that did not venture across the horizon (McGovern and Perdikaris, 2000.)
  • The Greenland Vikings lived mostly on dairy produce and meat, primarily from cows. The vegetable diet of Greenlanders included berries, edible grasses, and seaweed, but these were inadequate even during the best harvests. During the MWP, Greenland’s climate was so cold that cattle breeding and dairy farming could only be carried on in the sheltered fiords. The growing season in Greenland even then was very short. Frost typically occurred in August and the fiords froze in October. Before the year 1300, ships regularly sailed from Norway and other European countries to Greenland bringing with them timber, iron, corn, salt, and other needed items. Trade was by barter. Greenlanders offered butter, cheese, wool, and their frieze cloths, which were greatly sough after in Europe, as well as white and blue fox furs, polar bear skins, walrus and narwhal tusks, and walrus skins. In fact, two Greenland items in particular were prized by Europeans: white bears and the white falcon. These items were given as royal gifts. For instance, the King of Norway-Denmark sent a number of Greenland falcons as a gift to the King of Portugal, and received in return the gift of a cargo of wine (Stefansson, 1966.) Because of the shortage of adequate vegetables and cereal grains, and a shortage of timber to make ships, the trade link to Iceland and Europe was vital (Hermann, 1954.)

THE SUN

To support the sun being involved, here is another short video:

Another example of this warming comes from the production of wine and the trading boom and crop and animal growth and productivity during this medieval warming period in the Roman Empire. Vineyards on the Salisbury Plains, and other parts on England that wopuld be impossible today:

Farmers and peasants in medieval England launched a thriving wine industry south of Manchester. Good wines demand warm springs free of frosts, substantial summer warmth and sunshine without too much rain, and sunny days in the fall. Winters cannot be too cold — not below zero Fahrenheit for any significant period. The northern limit for grapes during the Middle Ages was about 300 miles above the current commercial wine areas in France and Germany. These wines were not simply marginal supplies, but of sufficient quality and quantity that, after the Norman conquest, the French monarchy tried to prohibit British wine production.

TREES

And my final example, one I used in a more layman way with high school students at West Ranch High School was the following. I have wanted to get this copied and up for a long time, and I have the time now. But for the tree lovers, the following will be new information to them surely… and note how the 1990 IPCC graph at the top of this post matches the Chinese one below. This much warmer weather/climate (by three[+] degrees) allowed for higher tree lines in the past:

3-Degrees Warmer

Tree rings can be counted to date the time of an event, and their summertime width is greater under good growing conditions (warmth, rainfall) than during poor growing seasons (cold, dry). They are limited by the distance back in time researchers can find live trees, dead trees, or buried wood from an earlier time which can be accurately dated to its growth period.

In mountainous northwestern Pakistan, more than 200,000 tree-ring measurements were assembled from 384 long-lived trees that grew on more than twenty individual sites. The 1,300-year temperature proxy shows the warmest decades occurred between 800 and 1000, and the coldest periods between 1500 and 1700.128

Mountain tree line elevations are another sensitive and highly accurate proxy for temperature change. A number of studies of European tree lines testify to the fact that tree lines, farming, and villages moved upslope during the Medieval Warming and back with the Little Ice Age.

A recent study of tree line dynamics in Western Siberia showed that advances in tree lines during the warmer weather of the 20th century were “part of a long-term reforestation of tundra environments.” Two Swiss scientists, Jan Esper and Fritz-Hans Schweingruber, note that “stumps and logs of Larix sibirica can be preserved for hundreds of years” and that “above the tree line in the Polar Urals such relict material from large, upright trees were sampled and dated, confirming the existence, around A.D. 1000, of a forest tree line 30 meters above the late 20th century limit.” They also note, “this previous forest limit receded around 1350, perhaps caused by a general cooling trend.” Thus, the Siberian tree lines testify to the Medieval Warming and the Little Ice Age well outside of Europe.129

Lisa J. Graumlich of Montana State University combined both tree rings and tree lines to assess past climate changes in California’s Sierra Nevada. The trees in the mountains’ upper tree lines are preserved in place, living and dead, for up to 3,000 years. Graumlich says:

A relatively dense forest grew above the current tree line from the beginning of our records to around 100 B.C., and again from A.D. 400 to 1000, when temperatures were warm. Abundance of trees and elevation of tree line declined very rapidly from A.D. 1000 to 1400, the period of severe, multi-decadal droughts. Tree lines declined more slowly from 1500 to 1900 under the cool temperatures of the Little Ice Age, reaching current elevations around 1900.130

Graumlich’s tree evidence confirms both of the last two 1,500-year cycles: the Roman Warming/Dark Ages climate cycle and the Medieval Warming/Little Ice Age. Severe drought, which has been documented in California during the latter part of the Medieval Warming, obscured the timing of the shift from the Medieval Warming to the Little Ice Age. However, both events were clearly evident.

Cave stalagmite cores confirm the global nature of the 1,500-year cycle found in ice cores, seabed sediments, and trees. Their carbon and oxygen isotopes and their trace element content vary with temperature. Moreover, the stalagmites go back further in time than the tree evidence. One German stalagmite goes back more than 17,000 years. Cave stalagmites have been found in Ireland, Germany, Oman, and South Africa whose layers all show the Little Ice Age, the Medieval Warming, the Dark Ages, and the Roman Warming.131 A number of the stalagmites also show the unnamed cold period that preceded the Roman Warming.

In southern Ontario, pollen shows that the warmth-loving beech trees of the Medieval Warming gradually gave way to cold tolerant oaks as the Little Ice Age came on—and then the forest became dominated by pine trees. The oak trees have been making a comeback in Ontario since 1850 and the beech trees can be expected to resurge as the Modern Warming continues in the centuries ahead.132

Remains of prehistoric villages in Argentina were analyzed by Marcela A. Cioccale of the National University of Cordoba to determine where Argentina’s native peoples lived over the past 1,400 years. Using carbon-14 dating, she found that the inhabitants clustered in the lower valleys during the Dark Ages period, and then moved higher up the slopes as the Medieval Warming brought “a marked increase of environmental suitability, under a relatively homogeneous climate.”133 Habitation moved up as high as 4,300 meters in the Central Peruvian Andes around 1000 as the Medieval Warming not only raised temperatures but created more stable conditions for farming. After 1320, people migrated back down the slopes as the colder, less stable climate of the Little Ice Age set in.

Yang Bao of the Chinese Academy of Sciences reconstructed China’s temperature history for the last 2,000 years from ice cores, lake sediments, peat bogs, tree rings, and the historic documents that date back farther in China than in any other country. He found China had its highest temperature during the second and third centuries, toward the end of the Roman Warming. China’s climate was also warm from 800 to 1400, cold from 1400 to 1920, and then began to warm again after 1920.134 (See Figure 4.1.)

MISC. EVIDENCES

The idea of a medieval warm period  was formulated for the first time in 1965 by the English climatologist Hubert H. Lamb[1].  Lamb, who founded the UK Climate Research Unit (CRU) in 1971, saw the peak of the warming period from 1000 to 1300, i.e. in the High Middle Ages. He estimated that temperatures then were 1-2 ° C above the normal period of  1931-1960. In the high North, it was even up to 4 degrees warmer. The regular voyages of the Vikings between Iceland and Greenland were rarely hindered by ice, and many burial places of the Vikings in Greenland still lie in the permafrost.

Glaciers were smaller than today

Also the global retreat of glaciers that occurred in the period between about 900 to 1300[2] speaks for the existence of the Medieval Warm Period. An interesting detail is that many glaciers pulling back since 1850 reveal plant remnants from the Middle Ages, which is a clear proof that the extent of the glaciers at that time was lower than today[3].

Furthermore, historical traditions show evidence of unusual warmth at this time. Years around 1180 brought the warmest winter decade ever known. In January 1186/87, the trees were in bloom near Strasbourg. And even earlier you come across a longer heat phase, roughly between 1021 and 1040. The summer of 1130 was so dry that you could wade through the river Rhine. In 1135, the Danube flow was so low that people could cross it on foot. This fact has been exploited to create foundation stones for the bridge in  Regensburg this year[4].

Clear evidence of the warm phase of the Middle Ages can also be found in the limits of crop cultivation. The treeline in the Alps climbed to 2000 meters, higher than current levels are[5]. Winery was possible in Germany at the Rhine and Mosel up to 200 meters above the present limits, in Pomerania, East Prussia, England and southern Scotland, and in southern Norway, therefore, much farther north than is the case today[6]. On the basis of pollen record there is evidence that during the Middle Ages, right up to Trondheim in Norway, wheat was grown and until nearly the 70th parallel/latitude barley was cultivated[4]. In many parts of the UK arable land reached heights that were never reached again later.

Also in Asia historical sources report that the margin of cultivation of citrus fruits was never as far north as in  the 13th century. Accordingly, it must have been warmer at the time about 1 ° C than today[7].

Archeology and history confirm interglacial

Insects can also be used as historical markers for climate. The cold sensitive beetle Heterogaster urticae was detected during the Roman Optimum and during the Norman High Middle Age in York. Despite the warming of the 20th century, this beetle is found today only in sunny locations in the south of England[8].

During the medieval climate optimum, the population of Europe reached hitherto unknown highs. Many cities were founded at this very time with high-altitude valleys, high pastures and cultivated areas, which were at the beginning of the Little Ice Age again largely abandoned[9].

The Middle Ages was the era of high culture of the Vikings. In this period their expansion occurred into present-day Russia and the settlement of Iceland, Greenland and parts of Canada and Newfoundland. In Greenland even cereals were grown about this time.. With the end of the Medieval Warm Period the heyday of the Vikings ended. The settlements in Greenland had to be abandoned as well as in the home country of Norway, during this time, many northern communities located at higher altitudes[10]. The history of the Vikings also corresponds very well to the temperature reconstructions from Greenland, which were carried out using ice cores. According to the reconstructions, Greenland was  at the time of the Vikings at least one degree warmer than in the modern warming period[11].

D’Souza Stumps Student on Climate Change Challenge

This comment below (left on my YouTube channel) is in response to the above video:

  • I can see that the earth is warming, and I’m an atheist. The first thing that made me start to worry was the burning of Yellowstone in 1988. Dinesh’s argument may have worked ten years ago, but he apparently isn’t in contact with nature like many more of us are. He probably has his nose stuck in books and data, and is rushing around at the same time denying to anyone willing to listen that the we have had five or more record breaking temperature years all in this century. As Jesus said, according to Thomas, the truth is there if you want to see it. It pays the get rich quick corporations not to want to see Global Warming. I wonder how much this guy makes and who is paying him?

The following is my expanded response to it:

Continuing…

First, my wife works for a large corporation, and they do nothing but kowtow to the idea man is causing global warming. Spending many millions on the environment, and working side-by-side (paying off) a few well-known environment groups. Second, stations with the longest “over 90-degree” and stations with the “over 100-degree” were much more plentiful in the past when there was MUCH less man-produced CO2 —

COMPARED TO AUSUST 1ST

COMPARED TO BROADER PAST:

In fact, leaving the U.S., the longest/hottest heat wave (THE MARBLE BAR HEATWAVE) was when CO2 WAS AT 305ppm. And fourthly, note that…

  1. The Mean Global Temperature has been stable since 1997, despite a continuous increase of the CO2 content of the air: how could one say that the increase of the CO2 content of the air is the cause of the increase of the temperature?
  2. 57% of the cumulative anthropic emissions since the beginning of the Industrial revolution have been emitted since 1997, but the temperature has been stable. How to uphold that anthropic CO2 emissions (or anthropic cumulative emissions) cause an increase of the Mean Global Temperature?

<<< The EXACT opposite of the paradigm.

Not only that, but lastly, a just published study in THE OPEN ATMOSPHERIC SCIENCE JOURNAL says that global cooling will occur over the next 50-years… and we are above 400ppms! (Note: I can give hundreds of studies on this

Run, the sky is falling!

Which is why many smart people say stuff like this:

  • “Doubling CO2 involves a 2% perturbation to this budget. So do minor changes in clouds and other features, and such changes are common. In this complex multifactor system, what is the likelihood of the climate (which, itself, consists in many variables and not just globally averaged temperature anomaly) is controlled by this 2% perturbation in a single variable? BELIEVING THIS IS PRETTY CLOSE TO BELIEVING IN MAGIC. Instead, you are told that it is believing in ‘science.’ Such a claim should be a tip-off that something is amiss. After all, science is a mode of inquiry rather than a belief structure….. The accumulation of false and/or misleading claims is often referred to as the ‘overwhelming evidence’ for forthcoming catastrophe. Without these claims, one might legitimately ask whether there is any evidence at all.” — MIT Climate Scientist Dr. Richard Lindzen (emphasis added)

(Above) The Paris Climate Agreement will cost at least $1 trillion per year, and climate activists say it will save the planet. The truth? It won’t do anything for the planet, but it will make everyone poorer–except politicians and environmentalists. Bjorn Lomborg explains.

CLIMATE CHANGE: WHAT’S SO ALARMING? || Are droughts, hurricanes, floods and other natural disasters getting stronger and more frequent? Are carbon dioxide emissions, global temperatures and sea levels putting us on a path for climate catastrophe? Bjorn Lomborg, Director of the Copenhagen Consensus Center, breaks down the facts about the environment and shows why the reality of climate change may be very different from what you hear in the media.

DO 97% OF CLIMATE SCIENTISTS REALLY AGREE? || Is it true that 97% of climate scientists agree that climate change is real? Where does the 97% figure come from? And if it is true, do they agree on both the severity of and the solution to climate change? New York Times bestselling author Alex Epstein, founder of the Center for Industrial Progress, reveals the origins of the “97%” figure and explains how to think more clearly about climate change.

FOSSIL FUELS: THE GREENEST ENERGY ||  To make earth cleaner, greener and safer, which energy sources should humanity rely on? Alex Epstein of the Center for Industrial Progress explains how modern societies have cleaned up our water, air and streets using the very energy sources you may not have expected–oil, coal and natural gas.

CLIMATE CHANGE: WHAT DO SCIENTISTS SAY? || Climate change is an urgent topic of discussion among politicians, journalists and celebrities…but what do scientists say about climate change? Does the data validate those who say humans are causing the earth to catastrophically warm? Richard Lindzen, an MIT atmospheric physicist and one of the world’s leading climatologists, summarizes the science behind climate change.

ARE ELECTRIC CARS REALLY GREEN? || Are electric cars greener than conventional gasoline cars? If so, how much greener? What about the CO2 emissions produced during electric cars’ production? And where does the electricity that powers electric cars come from? Environmental economist Bjorn Lomborg, director of the Copenhagen Consensus Center, examines how environmentally friendly electric cars really are.

IS CLIMATE CHANGE OUR BIGGEST PROBLEM? || Is man-made climate change our biggest problem? Are the wildfires, droughts and hurricanes we see on the news an omen of even worse things to come? The United Nations and many political leaders think so and want to spend trillions of tax dollars to reverse the warming trend. Are they right? Will the enormous cost justify the gain? Economist Bjorn Lomborg, director of the Copenhagen Consensus Center, explains the key issues and reaches some sobering conclusions.

CAN WE RELY ON WIND AND SOLAR ENERGY? || Is green energy, particularly wind and solar energy, the solution to our climate and energy problems? Or should we be relying on things like natural gas, nuclear energy, and even coal for our energy needs and environmental obligations? Alex Epstein of the Center for Industrial Progress explains. Learn about Alex Epstein’s book, The Moral Case for Fossil Fuels.

WHY I LEFT GREENPEACE || Patrick Moore explains why he helped to create Greenpeace, and why he decided to leave it. What began as a mission to improve the environment for the sake of humanity became a political movement in which humanity became the villain and hard science a non-issue.

WHAT THEY HAVEN’T TOLD YOU ABOUT CLIMATE CHANGE || Since time immemorial, our climate has been and will always be changing. Patrick Moore explains why “climate change,” far from being a recent human-caused disaster, is, for a myriad of complex reasons, a fact of life on Planet Earth.

THE TRUTH ABOUT CO2 || Global Warming activists will tell you that CO2 is bad and dangerous. The EPA has even classified it as a pollutant. But is it? Patrick Moore provides some surprising facts about the benefits of CO2 that you won’t hear in the current debate.

TREES ARE THE ANSWER || Everybody loves trees, so why are they so controversial? Patrick Moore untangles the knotty issue of “deforestation” and shows how, from a purely environmental perspective, it is possible and desirable to grow more trees and use more wood products.

WHY YOU SHOULD LOVE FOSSIL FUEL || Every year on Earth Day we learn how bad humanity’s economic development is for the health of the planet. But maybe this is the wrong message. Maybe we should instead reflect on how human progress, even use of fossil fuels, has made our environment cleaner and healthier. Alex Epstein of the Center for Industrial Progress explains.

IS ORGANIC FOOD WORTH THE COST? || Are organic foods really healthier than non-organic foods? Are they better for animals? Are they better for the environment? Bjorn Lomborg, president of the Copenhagen Consensus Center, explains.

CAN A DESERT NATION SOLVE THE WORLD’S WATER SHORTAGE? || From California to Africa, we are facing a global water shortage. But one tiny country, in the middle of a desert, has found remarkable solutions. Which country? And can we replicate its success?

Nobel Laureate Ivar Giaever Deconstructs Global Warming

Nobel laureate Ivar Giaever’s speech at the Nobel Laureates meeting 1st July 2015. Ivar points out the mistakes which Obama makes in his speeches about global warming, and shares other not-well known facts about the state of the climate.

Professor Ivar Giaever, the 1973 Nobel Prizewinner for Physics trashes the global warming/climate change/extreme weather pseudoscientific clap-trap and tells Obama he is “Dead Wrong”. This was the 2012 meeting of Nobel Laureates.

The “Expert” Fallacy ~ Global Warming

A great response to a mushy response to AGW skeptics, here is the typical charge:

Imagine your doctor tells you that you have dangerously high cholesterol and blocked arteries. She says you may drop dead soon. [Note: Based on comments/questions, I should clarify here. By “doctor”, I mean the entire medical establishment. So imagine you got not just a “second opinion,” but 100 opinions…and 97 say the same thing].You might have four basic reactions based on two dimensions, belief (or doubt) in the basic facts/science, and whether you commit to action or delay.

Here are some of the responses — in part — from WATTS UP WITH THAT:

1. A medical doctor is a highly-qualified professional.  Medical doctors must successfully complete a medical school, spend 3-7 years in residency actually treating patients, and be licensed by a state medical board composed mostly of proven doctors.

In contrast, anybody can call him- or herself a scientist and speak on behalf of science.  There are no licensing or certification requirements….

[….]

2. A medical doctor is accountable.  A doctor would lose patients or be fired if his or her advice isn’t sound.  A doctor can also be sued by a dissatisfied patient.  In a number of cases, doctors have been indicted.

A putative climate scientist can hardly even be criticized….

3. Patients have direct bidirectional communication with their doctor.  “Direct” means that the patient usually speaks face-to-face with the doctor.  “Bi-directional” means the patient can ask the doctor questions and get answers.  Very few accept TV personalities’ talk as real medical advice.

The so-called “climate science” is usually communicated to the public in third person point of view like “The scientists say that …”, “Majority of peer-reviewed articles conclude …”, and even “Models show that …” These used to be typical introductory clauses before statements about alleged climate dangers…..

[….]

4. One takes initiative to seek a doctor, rather than the other way around. Any unsolicited email offering a medical procedure or a wonder pill is sent straight to the spam folder.

But climate alarmism promoters always come unsolicited! …

[….]

5. Doctors do not demand patients to trust them.  They earn their trust.

Climate alarmists demand trust because they have earned mistrust.

I would like to finish by paraphrasing Edmund Burke:

  • Alleged science looks for defense from Washington when it fails in the real world.

Ann McElhinney Destroys SJW

YOUNG CONSERVATIVES HAT-TIP:

Temple University Students for Intellectual Freedom (TUSIF) hosted Ann McElhinney, the Irish documentary film maker behind the documentary film “Not Evil, Just Wrong”, which debunks myths surrounding global warming. Also speaking on the panel were Jennifer Stefano, Director of Energy and Labor Policy, AFP-PA; and Tom Pyle, President, American Energy Alliance. The event concluded with an always-entertaining, outrageous Q&A session. Entertainment provided by the Temple U. Socialists-Feminists, radical leftists. AFP chose to tour Pennsylvania due to the state’s history in the energy field and their vast resources of shale, crude oil, and coal. This is an opportunity for students to learn about how the left’s radical environmentalist agenda is harming America.

Stevin Koonin ~ Former Energy Dept. Undersecretary (Updated)

(Above video description) Former Energy Department Undersecretary Steven Koonin on how bureaucrats spin scientific data.

Former Energy Department Undersecretary Steven Koonin told The Wall Street Journal Monday that bureaucrats within former President Barack Obama’s administration spun scientific data to manipulate public opinion.

“What you saw coming out of the press releases about climate data, climate analysis, was, I’d say, misleading, sometimes just wrong,” Koonin said, referring to elements within the Obama administration he said were responsible for manipulating climate data.

He pointed to a National Climate Assessment in 2014 showing hurricane activity has increased from 1980 as an illustration of how federal agencies fudged climate data. Koonin said the NCA’s assessment was technically incorrect.

“What they forgot to tell you, and you don’t know until you read all the way into the fine print is that it actually decreased in the decades before that,” he said.

Here is Mark Levin on the above interview:

  • “We are very far from the knowledge needed to make good climate policy,” writes leading scientist Steven E. Koonin

Via The Wall Street Journal:

The idea that “Climate science is settled” runs through today’s popular and policy discussions. Unfortunately, that claim is misguided. It has not only distorted our public and policy debates on issues related to energy, greenhouse-gas emissions and the environment. But it also has inhibited the scientific and policy discussions that we need to have about our climate future.

My training as a computational physicist—together with a 40-year career of scientific research, advising and management in academia, government and the private sector—has afforded me an extended, up-close perspective on climate science. Detailed technical discussions during the past year with leading climate scientists have given me an even better sense of what we know, and don’t know, about climate. I have come to appreciate the daunting scientific challenge of answering the questions that policy makers and the public are asking.

The crucial scientific question for policy isn’t whether the climate is changing. That is a settled matter: The climate has always changed and always will. Geological and historical records show the occurrence of major climate shifts, sometimes over only a few decades. We know, for instance, that during the 20th century the Earth’s global average surface temperature rose 1.4 degrees Fahrenheit.

Nor is the crucial question whether humans are influencing the climate. That is no hoax: There is little doubt in the scientific community that continually growing amounts of greenhouse gases in the atmosphere, due largely to carbon-dioxide emissions from the conventional use of fossil fuels, are influencing the climate. There is also little doubt that the carbon dioxide will persist in the atmosphere for several centuries. The impact today of human activity appears to be comparable to the intrinsic, natural variability of the climate system itself.

Rather, the crucial, unsettled scientific question for policy is, “How will the climate change over the next century under both natural and human influences?” Answers to that question at the global and regional levels, as well as to equally complex questions of how ecosystems and human activities will be affected, should inform our choices about energy and infrastructure.

But—here’s the catch—those questions are the hardest ones to answer. They challenge, in a fundamental way, what science can tell us about future climates.

Even though human influences could have serious consequences for the climate, they are physically small in relation to the climate system as a whole. For example, human additions to carbon dioxide in the atmosphere by the middle of the 21st century are expected to directly shift the atmosphere’s natural greenhouse effect by only 1% to 2%. Since the climate system is highly variable on its own, that smallness sets a very high bar for confidently projecting the consequences of human influences.

[….]

We often hear that there is a “scientific consensus” about climate change. But as far as the computer models go, there isn’t a useful consensus at the level of detail relevant to assessing human influences.

[….]

Any serious discussion of the changing climate must begin by acknowledging not only the scientific certainties but also the uncertainties, especially in projecting the future. Recognizing those limits, rather than ignoring them, will lead to a more sober and ultimately more productive discussion of climate change and climate policies. To do otherwise is a great disservice to climate science itself.

The Great Flood of 1862 – California’s Counter Hysterical History

I Call B.S. for ALL the people that say this Oroville dam thingy is proof in some way of Climate Disruption (previously Climate Change, and Global Warming before that)! They are right though, Jerry Brown and the Democrats have spent sick money on dumb stuff rather than California’s infrastructure. Governor Brown — contrary to the excerpt from the article — didn’t follow his own advice:

  • “This matter needs to be investigated from top to bottom,” Alpert said. He said he finds it astounding that even as Gov. Jerry Brown has repeatedly touted preparedness for climate change, officials who manage the dam and other pieces of the state’s water system have “essentially ignored what the governor said was critical for the state of California – and they were allowed to do it.” — THE DESERT SUN

We have had 200-year long droughts, and worse rain (below)… when BIG-OIL didn’t exist. Are “warmists” this dumb? (Yes… the answer is yes.) How bout California — via the Democrats — stop spending money on dumb shite and prepare for what man is not causing… weather:

This event is known as “The Great Flood of 1862,” and can happen again… the above is a picture from Sacramento in 1862.

The Great Flood of 1862 was the largest flood in the recorded history of Oregon, Nevada, and California, occurring from December 1861 to January 1862. It was preceded by weeks of continuous rains and snows in the very high elevations that began in Oregon in November 1861 and continued into January 1862. This was followed by a record amount of rain from January 9–12, and contributed to a flood that extended from the Columbia River southward in western Oregon, and through California to San Diego, and extended as far inland as Idaho in the Washington Territory, Nevada and Utah in the Utah Territory, and Arizona in the western New Mexico Territory. Immense snowfalls in the mountains of the far western United States caused more flooding in Idaho, Arizona, New Mexico, and Sonora, Mexico the following spring and summer as the snow melted.

The event was capped by a warm intense storm that melted the high snow load. The resulting snow-melt flooded valleys, inundated or swept away towns, mills, dams, flumes, houses, fences, and domestic animals, and ruined fields.

WATTS UP WITH THAT has a story on this historical period in our past with the article starting out thus:

Summary: To boost our fear, activists and journalists report the weather with amnesia about the past. Ten year records become astonishing events; weather catastrophes of 50 or 100 years ago are forgotten. It makes for good clickbait but cripples our ability to prepare for the inevitable. California’s history of floods and droughts gives a fine example — if we listen to the US Geological Survey’s reminder of past megafloods, and their warning of the coming ARkStorm.

  • “A 43-day storm that began in December 1861 put central and southern California underwater for up to six months, and it could happen again.”

There are maps of the flooded areas included in what was flooded in the 1800s and what could be flooded again with a coming storm of similar size:

No Certain Doom – Climate Model Failure

(H-T WUWT) Scott Adams, author of the famous Dilbert Cartoon, has challenged readers to find a qualified scientist who thinks climate models do a good job of predicting the future.

Here is Scott’s Tweet:

Inconvenient Truths for FactCheck.org

(See a Christmas Conversation from 2014)

This may come as a shocker to some, but scientists are not always right — especially when under intense public pressure for answers.

Researchers with the IUCN Polar Bear Specialist Group (PBSG) recently admitted to experienced zoologist and polar bear specialist Susan Crockford that the estimate given for the total number of polar bars in the Arctic was “simply a qualified guess given to satisfy public demand.”

Crockford has been critical of official polar bear population estimates because they fail to include five large subpopulations of polar bears. Due to the uncertainty of the populations in these areas, PBSG did not include them in their official estimate — but the polar bear group did include other subpopulation estimates.

PBSG has for years said that global polar bear populations were between 20,000 and 25,000, but these estimates are likely much lower than how many polar bears are actually living in the world.

“Based on previous PBSG estimates and other research reports, it appears there are probably at least another 6,000 or so bears living in these regions and perhaps as many as 9,000 (or more) that are not included in any PBSG ‘global population estimate,’” Crockford wrote on her blog.

[….]

PBSG disclosed this information to Crockford ahead of the release of their Circumpolar Polar Bear Action Plan in which they intend to put a footnote explaining why their global population estimate is flawed.

“As part of past status reports, the PBSG has traditionally estimated a range for the total number of polar bears in the circumpolar Arctic,” PBSG says in its proposed footnote. “Since 2005, this range has been 20-25,000. It is important to realize that this range never has been an estimate of total abundance in a scientific sense, but simply a qualified guess given to satisfy public demand.”

“It is also important to note that even though we have scientifically valid estimates for a majority of the subpopulations, some are dated,” PBSG continues. “Furthermore, there are no abundance estimates for the Arctic Basin, East Greenland, and the Russian subpopulations.”

“Consequently, there is either no, or only rudimentary, knowledge to support guesses about the possible abundance of polar bears in approximately half the areas they occupy,” says PBSG. “Thus, the range given for total global population should be viewed with great caution as it cannot be used to assess population trend over the long term.”

PBSG’s admission also comes after academics and government regulators have touted their polar bear population estimates to show that polar bear numbers have grown since the 1960s. PBSG estimates have also been used to show that polar bear populations have stabilized over the last 30 years.

Polar bear populations became the centerpiece of the effort to fight global warming due to claims that melting polar ice caps would cause the bears to become endangered in the near future. Years ago, some scientists predicted the Arctic would be virtually ice free by now.

Polar bears became the first species listed under the Endangered Species Act because they could potentially be harmed by global warming. But some recent studies have found that some polar bear subpopulations have actually flourished in recent years.

“So, the global estimates were… ‘simply a qualified guess given to satisfy public demand’ and according to this statement, were never meant to be considered scientific estimates, despite what they were called, the scientific group that issued them, and how they were used,” Crockford said….

al-bear-gore

A polar-bear expert (researcher and zoologist) refutes FactCheck.org’s article continuing to tell the lie that polar bears are endangered. The article is titled over at Climate Depot as, “Polar Bear Expert refutes warmist Factcheck.org’s claims on on polar bears.” The actual article title is: Challenging Alaska polar bear research sound bites and bewildering ESA status.

It’s easy to take polar bear research papers at face value but it’s not very scientific. The snappy sound bites provided for the benefit of the media – whether they’re embedded in press releases or in published abstracts – don’t cut it with trained scientists. Trained scientists read the whole report, critically examine the evidence it contains and assess that evidence within the context of previous knowledge. That’s what they are trained to do.

I challenge the superficial summary on the status of Alaskan polar bear populations provided by FactCheck.org journalist Vanessa Schipani.  Schipani disputed a comment made by Alaska Senator Lisa Murkowski that, according to the latest research Alaskan polar bear population numbers are strong and healthy. I’m not especially interested in the political context of the statement, only Schipani’s bald claim that Murkowski’s declaration is false.

[….]

Insisting that because the ESA and the IUCN Red List consider polar bears threatened with extinction means polar bear populations currently must be population deficient is false and misleading – the statuses of ‘threatened’ and ‘vulnerable’ for polar bears are based on concerns of possible future declines only.

It is factually correct to say that present populations of polar bears in Alaska are healthy. Scientific studies on polar bears – when all of the data is taken into account and considered in the context of all research on these bears – indicates this statement is true.

All of the evidence suggests Southern Beaufort Sea polar bears have recovered from a known and predictable decline in numbers in the mid-2000s due to natural causes – designating “critical habitat” along the Alaska coast will not protect the bears from repeats of this natural hazard in the future – and Chukchi Sea bears have all the indicators of a stable or increasing population. Those are the scientific facts.

(read it all if you dare!)

Here are 5 or the 10 failed predictions regarding Polar Bears via What’s Up With That?

Prediction 1. Western Hudson Bay (WHB) polar bear numbers will continue to declinebeyond 2004 due to ever-earlier breakup and ever-later freeze-up of sea ice.

FAIL – An aerial survey conducted by Seth Stapleton and colleagues (2014) in 2011 produced an estimate of about 1030 bears and their report stated:

This figure is similar to a 2004 mark–recapture estimate but higher than projections indicating declining abundance since then.”

This 1030 figure is the one being used by the IUCN PBSG and Environment Canada for WHB, as a limited mark-recapture studyconducted the same year (Lunn and colleagues 2014) did not survey the entire WHB region and therefore not comparable to the 2004 count.

Prediction 2. Breakup of sea ice in Western Hudson Bay (WHB) will come progressively earlier and freeze-up dates progressively later (after 1999), as CO2 levels from burning fossil fuel increase global temperatures.

FAIL – Researchers Nick Lunn and colleagues (2014) determined thatthere has been no trend in breakup or freeze-up dates between 2001 and 2010. While no analyses of breakup or freeze-up dates for WHB since 2010 have been published, this pattern seems to havecontinued to at least 2015.

Prediction 3. Chukchi Sea polar bears will be the most harmed by summer sea ice declines because they experience some of the largest sea ice losses of any subpopulation (and thus, the longest open-water season each year).

FAILA recent study of Chukchi bears (2008-2011) found them in better condition than they were in the 1980s when summer open-water seasons were short – indeed, only Foxe Basin bears were fatter than Chukchi bears. They were also reproducing well (Rode et al. 2010, 2013, 2014), with some females raising litters of triplets (see lead photo), a rare sight outside Western Hudson Bay.

Prediction 4. Cannibalism will increase as summer sea ice extent declines worsen.

FAIL – Cannibalism is a natural phenomenon in polar bears and none of the few incidents reported recently have involved obviously thin or starving polar bears(even the most recent example, filmed in mid-August 2015 in Baffin Bay when sea ice levels in the region were high),despite the fact that 2012 recorded the lowest summer ice extent since 1979. Incidents of cannibalism cannot be said to be increasingbecause there is no scientific baseline to which recent occurrences can be compared.

Prediction 5. Drowning deaths of polar bears will increase as summer sea ice continues to decline (driven home by a high-profile incident in 2004).

FAIL – There have been no further confirmed reports of polar bear drowning deathsassociated with extensive open water swimming since that contentious 2004 event, even though the two lowest extents of summer sea ice have occurred since then (2007 and 2012). A more rigorous study of swimming prowess found polar bears, including cubs, are capable of successfully making long-distance swims.  Indeed, challenging open-water swims don’t happen only in summer: in late March 2015, a polar bear swam through open water from the pack ice off Newfoundland to the Hibernia oil platform well offshore.

Survey Results: Svalbard polar bear numbers increased 30 42% over last 11 years

Results of this fall’s Barents Sea population survey have been released by the Norwegian Polar Institute and they are phenomenal: despite several years with poor ice conditions, there are more bears now (~975) than there were in 2004 (~685) around Svalbard (a 30 42% increase) and the bears were in good condition.

July 2016 the Hottest On Record?

  • During the great heatwave of July, 2016 – temperatures in Ada, Minnesota averaged 16 degrees cooler than during July, 1936… Aurora, Illinois was about 13 degrees warmer in 1936… Same story in Bloomington, Indiana. (The Deplorable Climate Science Blog)
Residents of Lincoln, Nebraska spend the night on the lawn of the state capital on July 25, 1936. The temperature that night never fell below 91°, perhaps the warmest night ever recorded anywhere in the United States outside of the desert Southwest.

Residents of Lincoln, Nebraska spend the night on the lawn of the state capital on July 25, 1936. The temperature that night never fell below 91°, perhaps the warmest night ever recorded anywhere in the United States outside of the desert Southwest.

NOAA has found it necessary to monkey with July temperatures by 1,000% in order to note that 2016 is the hottest July on record. (Ditto)

In 1924 the outback Australian town of Marble Bar recorded the longest ever heatwave, setting a record for the most consecutive days above 100F (37.8C). In 1976 the United Kingdom sweltered in temperatures exceeding 90F (32.2C) for 15 consecutive days. A further five days saw temperatures reaching 95F (35C). Parts of the country’s southwest went for 45 days without rain, prompting terrible heath and forest fires that destroyed trees and crops. The heatwave came to a dramatic end in August, with severe thunderstorms rolling across the country.

You can see more on my post about the 1930’s being the hottest, globally

Climate experts say that July 2016 was the hottest month ever.  In the United States, it was one of the least hot months ever.

2015 was also said to be the hottest year… 1936 had the most hot days on record, not 2015. Claims 2015 is the warmest year on record ignore satellite data, which shows 2015 only ranks as the third-warmest year on record (CFACT). May I add to the satellite data being ignored that bad readings from many ground sensors are used to prop up temperatures.

More accurate measurements of the lower troposphere show that July was nowhere near as warm as 1998 and 2010.

This is why REAL SCIENCE notes that for Gavin A. Schmidt (of NASA) to say July is the hottest month on record is this most PROVABLY fraudulent statement yet.

The touting of all these “hottest years” and scare tactics and the U.N. saying rising oceans will threaten the Statue of Liberty, are all power grabs. Period. The EPA says their most strict legislative acts to implement new regulations that will fight global warming, are ALSO A LIE! Like the Arctic for years being prophesied to be ice-free, and in fact setting ice-expansion records during month it was suppose to be ice-free.

The DAILY CALLER notes the EPA Chief’s admission:

Environmental Protection Agency Administrator Gina McCarthy admitted her agency’s signature regulation aimed at tackling global warming was meant to show “leadership” rather than actually curb projected warming.

McCarthy admitted as much after being questioned by West Virginia Republican Rep. David McKinley, who pressed the EPA chief on why the Obama administration was moving forward with economically-damaging regulations that do nothing for the environment.

“I don’t understand,” McKinley said in a Tuesday hearing. “If it doesn’t have an impact on climate change around the world, why are we subjecting our hard working taxpayers and men and women in the coal fields to something that has no benefit?”…

Here is a great presentation showing the EPA to be full of B.S. Former Obama Department of Energy Assistant Secretary Charles McConnell eviscerates the President’s proposed Clean Power Plan regulation to fight global warming in testimony before Congress:

I said out-loud “AMEN” to the line, “I am no lawyer, but I AM a citizen!”
